Description:
CROSS REFERENCE TO RELATED APPLICATION 
     The present application claims priority from Japanese Patent Application No. 2017-073188, which was filed on Mar. 31, 2017, the disclosure of which is herein incorporated by reference in its entirety. 
     BACKGROUND 
     The following disclosure relates to a printing apparatus configured to perform printing on a medium to create a printed medium, to the medium, and to a non-transitory storage medium storing a plurality of instructions executable by a processor to create the printed medium. 
     There is known a technique for creating a medium wrapped around a cable or a circular cylindrical wrapped member. 
     SUMMARY 
     In the technique, the medium is wrapped around a wrapped member such that the medium does not adhere to the wrapped member. That is, in attachment, after wrapping a portion the medium around the wrapped member, a user sticks a distal end portion of the medium to a portion of the medium which is not wrapped around the wrapped member, whereby a cylindrical member surrounding the wrapped member is formed to attach the medium to the wrapped member. Since the medium is manually attached to the wrapped member, however, there is a possibility of misalignment and skew of the medium. 
     Accordingly, an aspect of the disclosure relates to a printing apparatus, a medium, and a non-transitory storage medium storing a plurality of instructions, which are capable of preventing misalignment and skew in attachment of the medium to a wrapped member. 
     In one aspect of the disclosure, a printing apparatus includes: a conveyor configured to convey a medium including a transparent base layer and a separation layer stacked on each other in a stacking direction, wherein a plurality of regions are defined in the medium along a first direction orthogonal to the stacking direction, and wherein the plurality of regions include (i) a first region in which a portion of the medium which is in contact with the separation layer is stickable, (ii) a second region which is located on one side of the first region in the first direction and in which a portion of the medium which is in contact with the separation layer is non-stickable, and (iii) a third region which is located on the one side of the second region in the first direction and in which at least a part of a portion of the medium which is in contact with the separation layer is stickable; a printer configured to print a character on the medium conveyed by the conveyor; and a controller configured to control the conveyor and the printer. The controller is configured to control the printer to print a first mark on a portion of the medium in one of the first region and a first-region-side portion of the second region and to print a second mark on a portion of the medium in one of the third region and a third-region-side portion of the second region such that the first mark and the second mark are arranged in a line in the first direction, wherein a center of the first-region-side portion of the second region is nearer to the first region than a center of the second region in the first direction, and a center of the third-region-side portion of the second region is nearer to the third region than the center of the second region in the first direction. 
     In another aspect of the disclosure, a printing apparatus includes: a conveyor configured to convey a medium including a transparent base layer and a separation layer stacked on each other in a stacking direction, wherein a plurality of regions are defined in the medium along a first direction orthogonal to the stacking direction, wherein the plurality of regions include (i) a first region in which a portion of the medium which is in contact with the separation layer is stickable, (ii) a second region which is located on one side of the first region in the first direction and in which a portion of the medium which is in contact with the separation layer is non-stickable, and (iii) a third region which is located on the one side of the second region in the first direction and in which at least a part of a portion of the medium which is in contact with the separation layer is stickable, wherein the medium includes a print mark on a portion of the medium in one of the first region and a first-region-side portion of the second region, and wherein a center of the first-region-side portion of the second region is nearer to the first region than a center of the second region in the first direction; a printer configured to print a character on the medium conveyed by the conveyor; and a controller configured to control the conveyor and the printer.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     Hereinafter, there will be described embodiments by reference to the drawings. 
     There will be described a first embodiment with reference to  FIGS. 1-21 . 
     Label Creating Apparatus 
     There will be described a label creating apparatus according to the present embodiment with reference to  FIG. 1 . 
     In  FIG. 1 , a label creating apparatus  1  as one example of a printing apparatus includes: a control circuit  2 ; an operation device  3  configured to accept operations of a user (an operator); a display  4 ; a memory  5  configured to store various kinds of information; a conveying roller  6  as one example of a conveyor; a thermal head  7  as one example of a printer; and cutters  9 . 
     The label creating apparatus  1  includes a cartridge holder  12  having a housing  11 , on which a tape cartridge  10  is mountable removably. The tape cartridge  10  accommodates a tape roll  10 A having a spiral shape. It is noted that  FIG. 1  illustrates the tape roll  10 A in the form of concentric circles for simplicity. The tape roll  10 A is a roll of a print tape To as one example of a tape. Examples of the tape cartridge  10  include: a tape cartridge of a die-cut-label type in which the print tape To having half-cut regions HC (see  FIGS. 2A and 2B  which will be described below) formed by half cut (kiss cut) of the print tape To is rolled; and a tape cartridge of what is called a continuous type (see  FIGS. 10A and 10B  which will be described below) in which the print tape To having no half-cut regions HC is rolled. In the label creating apparatus  1 , any of the types of the tape cartridge  10  can be used. A cartridge sensor CS provided on the cartridge holder  12  detects which type of the tape cartridge  10  is used. The cartridge sensor CS, based on this detection, sends the control circuit a corresponding detection signal as cartridge type information, in other words, information about the type of the print tape To. It is noted that the following explanation is provided assuming that the tape cartridge  10  of the die-cut-label type is used, unless otherwise specified. 
     The control circuit  2  includes a central processing unit (CPU) and a read-only memory (ROM), not illustrated. The control circuit  2  is configured to execute various programs stored in the ROM and control overall operations of the label creating apparatus  1  while using a temporary storage function of a RAM of the memory  5 . 
     The conveying roller  6  is opposed to the thermal head  7 . The print tape To fed from the tape roll  10 A is nipped between the conveying roller  6  and the thermal head  7 . The conveying roller  6  is rotated by control of the control circuit  2  (specifically, a controller  500  which will be described below) so as to convey the print tape To while drawing the print tape To out from the tape roll  10 A. In the following description, the control of the control circuit  2  is similar to control of the controller  500  in meaning. 
     The thermal head  7  is controlled by the control circuit  2  to print a desired print object, such as characters and figures, on each of label portions (which will be described later in detail) of the print tape To conveyed by the conveying roller  6 . 
     In this example, the cutters  9  are controlled by the control circuit  2  to cut a print tape T (which will be described later in detail) on which a plurality of print labels L (each one example of a printed medium) are printed along a conveying direction. It is noted that a cut lever, not illustrated, may be provided so as to be operable by the user to actuate the cutters  9 . It is noted that each of the print tapes To, T is one example of a medium. 
     Print Tape 
       FIG. 2A  illustrates the print tape To.  FIG. 2A  is a plan view of the print tape To in an unprinted state. In  FIG. 2A , the right and left direction coincides with the conveying direction (in other words, the longitudinal direction of the tape), the up and down direction coincides with the widthwise direction of the tape, and the front and back direction of the sheet on which  FIG. 2A  is illustrated coincides with the thickness direction of the tape. In  FIG. 2A , the print tape To has substantially rectangular half-cut regions HC (see  FIG. 3B  which will be described below) formed by cutting a base layer  21  and an adhesive layer  22 . Portions of the print tape To inside the half-cut regions HC are label portions LA, and a portion of the print tape To outside the half-cut regions HC is a non-label portion LB. It is noted that a print tape from which the non-label portion LB is peeled off in advance may be used as the print tape To. The label portions LA are arranged in the longitudinal direction of the tape. Each of the label portions LA includes an adhesive region D 1 , a non-adhesive region D 2   a , a non-adhesive region D 2   b , and a partly-adhesive region D 3  arranged in order toward one side in the widthwise direction of the tape (downward in  FIG. 2A ). These regions will be described below. 
       FIG. 2B  illustrates the print tape T on which character strings R are formed. In this example,  FIG. 2B  is a plan view of the print tape T after the character strings R are respectively printed on printing background layers  25  (which will be described below) in the respective non-adhesive regions D 2   b  of the regions D 1 -D 4 . In this example, as illustrated in  FIG. 2B , text objects as the print objects, i.e., the character strings R (“A01”, “A02”, “A03”, and so on) are formed in order by the thermal head  7  on the respective label portions LA to create the print labels L. Also, marks M 1  are printed on the adhesive regions D 1  by the thermal head  7 , and likewise marks M 2  are printed on the partly-adhesive regions D 3 . It is noted that the print tape T may be configured such that the mark M 1  is formed on the print tape To in advance, and the mark M 2  is printed on the print tape To by the thermal head  7  (see  FIG. 19  which will be described below), for example. Conversely, the print tape T may be configured such that the mark M 2  is formed on the print tape To in advance, and the mark M 1  is printed on the print tape To by the thermal head  7  (not illustrated). 
     Print Label 
     There will be next described the structure of the print label L with reference to  FIGS. 3A and 3B .  FIG. 3A  is plan view of one print label L separated from the non-label portion LB.  FIG. 3B  is a cross-sectional view taken along line IIIB-IIIB in  FIG. 2B . 
     In  FIGS. 3A and 3B , each of the print labels L is constituted by the transparent base layer  21 , the transparent adhesive layer  22 , a transparent non-adhesive layer  23 , and a separation layer  24  which are stacked on one another from the left side toward the right side in  FIG. 3B  (from the front side toward the back side in  FIG. 3A ) in a thickness direction of the print label L (i.e., the depth direction of the sheet in  FIG. 3A  and the right and left direction in  FIG. 3B ). The thickness direction is one example of a stacking direction in which the layers are stacked on one another. It is noted that since each of the print tapes To, T has this stacking structure, each of the print tapes To, T has the base layer  21 , the adhesive layer  22 , the non-adhesive layer  23 , and the separation layer  24  each elongated in the right and left direction in  FIGS. 2A and 2B  (as one example of a second direction orthogonal to each of a first direction and the thickness direction). 
     The printing background layer  25  having a non-transparent color on which the character string R is formed by the thermal head  7  is provided on a portion of a front surface of the base layer  21  (i.e., a left surface thereof in  FIG. 3B  which is a one-side surface thereof in the thickness direction). The non-adhesive layer  23  is provided between a portion of the adhesive layer  22  and a portion of the separation layer  24 . While the adhesive layer  22  is provided on the entire back surface of the base layer  21  (i.e., a right surface in  FIG. 3B  which is an other-side surface thereof in the thickness direction) between the base layer  21  and the separation layer  24  in this example, the adhesive layer  22  may be provided on a portion of the back surface of the base layer  21 . 
     In view of the above, the print label L has the four regions along the direction orthogonal to the thickness direction (i.e., the up and down direction in  FIGS. 3A and 3B , the circumferential direction of a wrapped member  302  which will be described below, and the first direction). The four regions include: the adhesive region D 1  (as one example of a first region in this example) constituting an upper end portion of the print label L in  FIGS. 3A and 3B  in the first direction (noted that the upper side in  FIGS. 3A and 3B  may be referred to as “the other side in the first direction”); the non-adhesive region D 2   a  (as one example of a second region in this example) located contiguous to and under the adhesive region D 1  in  FIGS. 3A and 3B  (noted that the lower side in  FIGS. 3A and 3B  may be referred to as “one side in the first direction”); the non-adhesive region D 2   b  (as another example of the second region in this example) located contiguous to and under the non-adhesive region D 2   a  in  FIGS. 3A and 3B ; and the partly-adhesive region D 3  (as one example of a third region in this example) located contiguous to and under the non-adhesive region D 2   b  in  FIGS. 3A and 3B . 
     In the adhesive region D 1 , the base layer  21 , the adhesive layer  22 , and the separation layer  24  are stacked in order from the one side toward the other side in the thickness direction (from the left side toward the right side in  FIG. 3B ). Thus, the entire portion of the adhesive region D 1  which is in contact with the separation layer  24  has adhesiveness owing to the adhesive layer  22 . The adhesiveness is one example of stickability in this specification. It is noted that the adhesive region D 1  has a length L 1  in the first direction. It is noted that a region in the print label L which is occupied by the adhesive region D 1  extends in the first direction by the length L 1  from an upper end of the print label L in the first direction, and is interposed in the second direction between opposite end portions of the base layer  21  in the second direction in the region extending from the upper end by the length L 1 . 
     In the non-adhesive region D 2   a , the base layer  21 , the adhesive layer  22 , the non-adhesive layer  23 , and the separation layer  24  are stacked in order from the one side toward the other side in the thickness direction (from the left side toward the right side in  FIG. 3B ). Thus, the entire portion of the non-adhesive region D 2   a  which is in contact with the separation layer  24  is not adhesive (non-adhesiveness) because the adhesiveness of the adhesive layer  22  is interrupted by the non-adhesive layer  23 . It is noted that the non-adhesiveness is one example of non-stickability in this specification. It is noted that the non-adhesive region D 2   a  has a length L 2  in the first direction. It is noted that a region in the print label L which is occupied by the non-adhesive region D 2   a  extends in the first direction by the length L 2  from a lower end of the adhesive region D 1 , and is interposed in the second direction between the opposite end portions of the base layer  21  in the second direction in the region extending from the lower end of the adhesive region D 1  by the length L 2 . 
     In the non-adhesive region D 2   b , the printing background layer  25 , the base layer  21 , the adhesive layer  22 , the non-adhesive layer  23 , and the separation layer  24  are stacked in order from the one side toward the other side in the thickness direction (from the left side toward the right side in  FIG. 3B ). Thus, the entire portion of the non-adhesive region D 2   b  which is in contact with the separation layer  24  is not adhesive because the adhesiveness of the adhesive layer  22  is interrupted by the non-adhesive layer  23 . In this example, the printing background layer (ink coated layer)  25  is formed by coating the base layer  21  with ink of an appropriate color, for example. The character string R (the text “A01”) is formed by the thermal head  7  on a portion of the print label L in a character-string print region RA that is set in advance on the printing background layer  25  in the non-adhesive region D 2   b , as a region on which characters are printable by the thermal head  7 . It is noted that right and left end portions of the character-string print region RA in the second direction in  FIG. 3A  are margin regions RS on which no characters are formed by the thermal head  7 . Since the sizes of the margin regions RS are changeable as will be described later in detail, the size of the character-string print region RA is also changeable, which will also be described later. It is noted that the non-adhesive region D 2   b  has a length L 3  in the first direction. It is noted that a region in the print label L which is occupied by the non-adhesive region D 2   b  extends in the first direction by the length L 3  from a lower end of the non-adhesive region D 2   a  and is interposed in the second direction between the opposite end portions of the base layer  21  in the second direction in the region extending from the lower end of the non-adhesive region D 2   a  by the length L 3 . 
     The partly-adhesive region D 3  includes: a non-adhesive region D 3   a  (as one example of a first-portion region in this example) provided contiguous to and under the non-adhesive region D 2   b  in  FIGS. 3A and 3B ; and an adhesive region D 3   b  (as one example of a second-portion region in this example) provided contiguous to and under the non-adhesive region D 3   a  in  FIGS. 3A and 3B  and defines a lower end of the print label L in the first direction in  FIGS. 3A and 3B . 
     In the non-adhesive region D 3   a , the base layer  21 , the adhesive layer  22 , the non-adhesive layer  23 , and the separation layer  24  are stacked in order from the one side toward the other side in the thickness direction (from the left side toward the right side in  FIG. 3B ). Thus, the entire portion of the non-adhesive region D 3   a  which is in contact with the separation layer  24  is not adhesive because the adhesiveness of the adhesive layer  22  is interrupted by the non-adhesive layer  23 . It is noted that the non-adhesive region D 3   a  has a length L 4 A in the first direction. It is noted that a region in the print label L which is occupied by the non-adhesive region D 3   a  extends in the first direction by the length L 4 A from a lower end of the non-adhesive region D 2   b , and is interposed in the second direction between the opposite end portions of the base layer  21  in the second direction in the region extending from the lower end of the non-adhesive region D 2   b  by the length L 4 A. 
     In the adhesive region D 3   b , the base layer  21 , the adhesive layer  22 , and the separation layer  24  are stacked in order from the one side toward the other side in the thickness direction (from the left side toward the right side in  FIG. 3B ). Thus, at least a part of a portion of the adhesive region D 3   b , which portion is in contact with the separation layer  24 , has adhesiveness owing to the adhesive layer  22 . It is noted that the adhesive region D 3   b  has a length L 4 B in the first direction. As a result, the partly-adhesive region D 3  has a length L 4  (=L 4 A+L 4 B) in the first direction, and at least a portion of the partly-adhesive region D 3  is adhesive. A region in the print label L which is occupied by the adhesive region D 3   b  extends in the first direction by the length L 4 B from a lower end of the non-adhesive region D 3   a , and is interposed in the second direction between the opposite end portions of the base layer  21  in the second direction in the region extending from the lower end of the non-adhesive region D 3   a  by the length L 4 B. 
     It is noted that a well-known release processing is applied at least to a surface of the separation layer  24  which is in contact with the adhesive layer  22  in the adhesive region D 1  and to a surface of the separation layer  24  which is in contact with the adhesive layer  22  in a portion of the partly-adhesive region D 3  (e.g., the adhesive region D 3   b ). As a result, when the separation layer  24  is peeled off, the adhesive layer  22  clings to the base layer  21  and is kept unseparated therefrom at least in the adhesive region D 1  and the adhesive region D 3   b . The release processing may not be applied to the surface of the separation layer  24  which is in contact with the adhesive layer  22  in the adhesive region D 1  but be applied to the surface of the base layer  21  which is in contact with the adhesive layer  22  in the adhesive region D 1 . With this structure, when the separation layer  24  is peeled off, the adhesive layer  22  does not remain on the base layer  21  in the adhesive region D 1 . In the region D 3   a , in this case, the base layer  21 , the adhesive layer  22 , and the separation layer  24  need to be stacked in order from the one side toward the other side in the thickness direction, and the release processing needs to be applied to the separation layer  24 . Also, the base layer  21  does not have perforation or slits (except the half-cut regions HC), and the cross-sectional shape of the base layer  21  in the thickness direction is continuous in the first direction. 
     As described above, the two first marks M 1  are printed by the thermal head  7  on the base layer  21  in the adhesive region D 1  (or the non-adhesive region D 2   a ) so as to be arranged in the right and left direction in  FIG. 3A  (i.e., the second direction), and the two second marks M 2  are printed by the thermal head  7  on the base layer  21  in the partly-adhesive region D 3  (specifically, the non-adhesive region D 3   a ) so as to be arranged in the right and left direction in  FIG. 3A  (i.e., the second direction). 
     Positions of each of the first marks M 1  and the second marks M 2  in the first direction and the second direction are determined by control of the control circuit  2  for the thermal head  7  and the conveying roller  6  (see a circumferential-direction mark-position setter  408  and an axial-direction mark-position setter  409  which will be described below, for example). In this example, in particular, the two first marks M 1  and the two second marks M 2  are formed such that each of the two first marks M 1  and a corresponding one of the two second marks M 2  are arranged along the up and down direction in  FIG. 3A  (i.e., the first direction). Specifically, the center of left first mark M 1  in  FIG. 3A  and the center of the left second mark M 2  in  FIG. 3A  are arranged along the up and down direction in  FIG. 3A  (i.e., the first direction), and likewise the center of right first mark M 1  in  FIG. 3A  and the center of the right second mark M 2  in  FIG. 3A  are arranged along the up and down direction in  FIG. 3A  (i.e., the first direction). In this example, the first marks M 1  and the second marks M 2  have the same shape (square in this example). 
     As illustrated in  FIG. 3A , assuming that the print label L is divided into three regions in the second direction, namely, a left end region W 1 , a central region W 2 , and a right end region W 3 , the marks M 1 , M 2  are formed on opposite end portions of the print label L in the second direction, i.e., the left end region W 1  and the right end region W 3 . It is noted that the second marks M 2  may be respectively formed on the opposite end portions of the character-string print region RA in the second direction in the non-adhesive region D 2   b.    
     Procedure of Attachment of Print Label to Wrapped Member 
       FIGS. 4A-4C  illustrate one example of a procedure of attachment of the print labels L to the wrapped member. In this example,  FIGS. 4A-4C  illustrate one example of wrapping the print label L around the wrapped member  302  shaped like a circular cylinder or a cable and having a diameter 2r. 
     As illustrated in  FIG. 4A , the separation layer  24  is first peeled off from the print label L having the above-described structure to expose the non-adhesive layer  23  and so on. While the print label L is constituted by the adhesive region D 1 , the non-adhesive region D 2   a , the non-adhesive region D 2   b , and the partly-adhesive region D 3  arranged in this order, the portions of the print label L in the adhesive region D 1 , the non-adhesive region D 2   a , and the non-adhesive region D 2   b  are then bent in a concave shape such that a portion of the print label L which had been in contact with the separation layer  24  (a right portion of the print label L in  FIG. 4A ) is located on an inner side (not illustrated). 
     As illustrated in  FIG. 4B , the wrapped member  302  is placed on an inner portion of the concave portion of the print label L, and the print label L is wrapped around the wrapped member  302  so as to form a cylindrical member surrounding the wrapped member  302 . Then, the adhesive layer  22  in the adhesive region D 1  as a part of a distal end portion of the print label L (noted that the adhesive layer  22  in the adhesive region D 1  serves as a sticking portion in inner-sides sticking which will be described below) and the non-adhesive layer  23  in the non-adhesive region D 3   a  of the partly-adhesive region D 3  (which serves as a stuck portion in the inner-sides sticking which will be described below) are stuck together. This sticking may be hereinafter referred to as “inner-sides sticking”. This sticking is performed such that each of the two first marks M 1  in the adhesive region D 1  and the corresponding one of the two second marks M 2  in the non-adhesive region D 3   a  are located at the same position when viewed in the right and left direction in  FIG. 4B  (see  FIGS. 4B and 4C ). 
     In this state, the sum of the lengths L 2 , L 3 , L 4 A of the non-adhesive layer  23  in the first direction is at least greater than or equal to the circumference of a circle 2πr of the wrapped member  302 . As a result, the shape of the print label L is fixed by sticking of the portions of the adhesive layer  22 , and the print label L is wrapped around the wrapped member  302  in the non-adhesive region D 2   a  and the non-adhesive region D 2   b  without adhesive, whereby the print label L is rotatably attached to the wrapped member  302 . 
     Thereafter, the rest portion (the adhesive region D 3   b  in this example) of the partly-adhesive region D 3  which is not used for surrounding the wrapped member  302  is wrapped around an outer circumferential portion of the print label L in the regions D 2 , D 3  (see  FIG. 4C ) so as to cover the non-adhesive region D 2   a  and the non-adhesive region D 2   b  constituting the cylindrical member in this order such that the stuck portions of the print label L in the adhesive region D 1  and the non-adhesive region D 3   a  are folded into an inner circumferential side as indicated by arrow G in  FIG. 4B  (such that the adhesive region D 1  as the sticking portion is folded along arrow A and brought into contact with an area B in  FIG. 4B ). The portion of the print label L in the adhesive region D 3   b  of the partly-adhesive region D 3  is stuck to the outer circumferential portion of the print label L in the non-adhesive region D 2   a  and the non-adhesive region D 2   b  using adhesiveness of the adhesive layer  22 , and the attachment of the print label L to the wrapped member  302  is finished. 
     Example of Use of Print Label 
       FIG. 5  illustrates one example of use of the print labels L. In this example, cables used for a switching hub configured to relay information over a wired LAN are used each as the wrapped member  302 . These cables will be hereinafter referred to as “cables  302 ”. As illustrated in  FIG. 5 , a switching hub  300  has sixteen slots  301 , eight of which are formed in an upper portion of the switching hub  300 , and the other eight of which are formed in a lower portion of the switching hub  300 . In the illustrated example, plates PL indicating identification names “A01”-“A08” are provided respectively for the upper eight slots  301  so as to be arranged in this order from the left. Also, plates PL indicating identification names “A09”-“A16” are provided respectively for the lower eight slots  301  so as to be arranged in this order from the left. 
     Each of the cables  302  is connected to a corresponding one of the slots  301 . For easy connection, the print labels L are attached to end portions of the respective cables  302  such that the same character strings R as the respective identification names of the slots  301  are printed on the respective print labels L to indicate the corresponding slots  301 . That is, the print labels L on which the same texts as the identification names of the plates PL are printed are attached to the respective cables  302  to indicate which slot  31  each cable  302  is to be connected to. This configuration clarifies a relationship between the slots  301  and the cables  302 , thereby preventing erroneous connection. 
     Each of  FIGS. 6A and 6B  schematically illustrates a state in which the print label L is attached to the cable  302 .  FIGS. 6A and 6B  also illustrate axes k of the cables  302 . As described above, the print label L is rotatably attached to the cable  302  as the wrapped member. In the state illustrated in  FIG. 6A , for example, the print label L is in a state in which the non-adhesive region D 2   b  in which the character string R representing “A01” is printed is on a front side in  FIG. 6A . It is noted that the transparent adhesive region D 3   b  covers the outer circumferential portion of the non-adhesive region D 2   b  in reality as illustrated in  FIG. 4C , but illustration of the transparent adhesive region D 3   b  is omitted in  FIGS. 6A and 6B  for simplicity. When the print label L is rotated in a direction indicated by the broken-line arrow (i.e., in the circumferential direction) from the state illustrated in  FIG. 6A , for example, the partly-adhesive region D 3  of the print label L is located on the front side as illustrated in  FIG. 6B . In the case where the print label L is fixed to the cable  302  at the position in  FIG. 6B , the viewability of the character string R is low. However, since the print label L is rotatable in this example, the viewability of the character string R is increased by rotating the print label L in a direction reverse to the above-described direction to the position in  FIG. 6A . 
     Another Sticking Manner 
     In the label creating apparatus  1  according to the present embodiment, the print label L may be created in a sticking manner different from the above-described manner.  FIG. 7A  is a plan view of a print label L to be stuck in another sticking manner.  FIG. 7A  corresponds to  FIG. 3A .  FIG. 7B  is a cross-sectional view taken along line VIIB-VIIB in  FIG. 7A .  FIG. 7B  generally corresponds to  FIG. 3B . In this case, the print label L in  FIGS. 7A and 7B  is formed by displacing the printing background layer  25  in advance for a structure of the print label L in the print tapes To, T illustrated in  FIGS. 2A through 3B  (not illustrated). 
     In  FIGS. 7A and 7B , the print label L (in other words, the print tapes To, T) includes the transparent base layer  21 , the transparent adhesive layer  22 , the transparent non-adhesive layer  23 , and the separation layer  24  which are stacked on one another in this order from the left side toward the right side in  FIG. 7B  along the thickness direction of the print label L. 
     As in the above-described structure, the printing background layer  25  is provided on a portion of a front surface of the base layer  21 , and the non-adhesive layer  23  is provided between a portion of the adhesive layer  22  and a portion of the separation layer  24 . 
     In view of the above, the print label L in this example has four regions along the first direction. The four regions include: an adhesive region D 5  (as one example of the first region in this example) constituting an end portion of the print label L in the first direction; a non-adhesive region D 6   a  (as one example of the second region in this example) provided contiguous to and under the adhesive region D 5  in  FIGS. 7A and 7B ; a non-adhesive region D 6   b  (as one example of the second region in this example) provided contiguous to and under the non-adhesive region D 6   a  in  FIGS. 7A and 7B ; and a partly-adhesive region D 7  (as one example of the third region in this example) provided contiguous to and under the non-adhesive region D 6   b  in  FIGS. 7A and 7B . 
     In the adhesive region D 5 , as in the adhesive region D 1 , the base layer  21 , the adhesive layer  22 , and the separation layer  24  are stacked in order from the left side toward the right side in  FIG. 7B . A portion of the adhesive region D 5 , which portion is in contact with the separation layer  24 , has adhesiveness. It is noted that the adhesive region D 5  has a length L 5  in the first direction. It is noted that a region in the print label L which is occupied by the adhesive region D 5  extends in the first direction by the length L 5  from an upper end of the print label L in the first direction, and is interposed in the second direction between the opposite end portions of the base layer  21  in the second direction in the region extending from the upper end by the length L 5 . 
     In the non-adhesive region D 6   a , as in the non-adhesive region D 2   b , the printing background layer  25 , the base layer  21 , the adhesive layer  22 , the non-adhesive layer  23 , and the separation layer  24  are stacked in order from the one side toward the other side in the thickness direction (from the left side toward the right side in  FIG. 7B ). Thus, the entire portion of the non-adhesive region D 6   a  which is in contact with the separation layer  24  is not adhesive because the adhesiveness of the adhesive layer  22  is interrupted by the non-adhesive layer  23 . The printing background layer  25  is an ink coated layer. The character string R (the text “A01”) is formed by the thermal head  7  on the character-string print region RA that is set in advance on the printing background layer  25  in the non-adhesive region D 6   a , as a region on which characters are printable by the thermal head  7 . It is noted that the non-adhesive region D 6   a  has a length L 6  in the first direction. It is noted that a region in the print label L which is occupied by the non-adhesive region D 6   a  extends in the first direction by the length L 6  from a lower end of the adhesive region D 5 , and is interposed in the second direction between the opposite end portions of the base layer  21  in the second direction in the region extending from the lower end of the adhesive region D 5  by the length L 6 . 
     In the non-adhesive region D 6   b , as in the non-adhesive region D 2   a , the base layer  21 , the adhesive layer  22 , the non-adhesive layer  23 , and the separation layer  24  are stacked in order from the one side toward the other side in the thickness direction (from the left side toward the right side in  FIG. 7B ). Thus, the entire portion of the non-adhesive region D 6   b  which is in contact with the separation layer  24  is not adhesive because the adhesiveness of the adhesive layer  22  is interrupted by the non-adhesive layer  23 . It is noted that the non-adhesive region D 6   b  has a length L 7  in the first direction. It is noted that a region in the print label L which is occupied by the non-adhesive region D 6   b  extends in the first direction by the length L 7  from a lower end of the adhesive region D 6   a , and is interposed in the second direction between the opposite end portions of the base layer  21  in the second direction in the region extending from the lower end of the adhesive region D 6   a  by the length L 7 . 
     The partly-adhesive region D 7  includes: a non-adhesive region D 7   a  (as one example of the first-portion region in this example) provided contiguous to and under the non-adhesive region D 6   b  in  FIGS. 7A and 7B ; and an adhesive region D 7   b  (as one example of a second-portion region in this example) provided contiguous to and under the non-adhesive region D 7   a  in  FIGS. 7A and 7B  and defines a lower end of the print label L in the first direction in  FIGS. 7A and 7B . 
     In the non-adhesive region D 7   a , as in the non-adhesive region D 3   a , the base layer  21 , the adhesive layer  22 , the non-adhesive layer  23 , and the separation layer  24  are stacked in order from the one side toward the other side in the thickness direction (from the left side toward the right side in  FIG. 8B ). Thus, the entire portion of the non-adhesive region D 7   a  which is in contact with the separation layer  24  is not adhesive because the adhesiveness of the adhesive layer  22  is interrupted by the non-adhesive layer  23 . It is noted that the non-adhesive region D 7   a  has a length L 8 A in the first direction. A region in the print label L which is occupied by the non-adhesive region D 7   a  extends in the first direction by the length L 8 A from a lower end of the non-adhesive region D 6   b , and is interposed in the second direction between the opposite end portions of the base layer  21  in the second direction in the region extending from the lower end of the non-adhesive region D 6   b  by the length L 8 A. 
     In the adhesive region D 7   b , as in the adhesive region D 3   b , the base layer  21 , the adhesive layer  22 , and the separation layer  24  are stacked in order from the one side toward the other side in the thickness direction (from the left side toward the right side in  FIG. 8B ). Thus, at least a part of a portion of the adhesive region D 7   b , which portion is in contact with the separation layer  24  has adhesiveness owing to the adhesive layer  22 . It is noted that the adhesive region D 7   b  has a length L 8 B in the first direction. As a result, the partly-adhesive region D 7  has a length L 8  (=L 8 A+L 8 B) in the first direction, and at least a portion of the partly-adhesive region D 7  is adhesive. A region in the print label L which is occupied by the adhesive region D 7   b  extends in the first direction by the length L 8 B from a lower end of the non-adhesive region D 7   a , and is interposed in the second direction between the opposite end portions of the base layer  21  in the second direction in the region extending from the lower end of the non-adhesive region D 7   a  by the length L 8 B. 
     It is noted that, as in the above-described structure, the well-known release processing is applied at least to a surface of the separation layer  24  which is in contact with the adhesive layer  22  in the adhesive region D 5  and to a surface of the separation layer  24  which is in contact with the adhesive layer  22  in a portion of the partly-adhesive region D 7  (e.g., the adhesive region D 7   b ). The well-known release processing is also applied at least to a surface of the base layer  21  which is in contact with the adhesive layer  22  (i.e., the other-side surface of the base layer  21  in the thickness direction) in the adhesive region D 5 . As a result, when the separation layer  24  is peeled off, the adhesive layer  22  clings to the base layer  21  and is kept unseparated at least in the adhesive region D 5  and the adhesive region D 7   b . Also, the base layer  21  does not have perforation or slits, and the cross-sectional shape of the base layer  21  in the thickness direction is continuous in the first direction. 
     Also in this case, the two first marks M 1  are printed by the thermal head  7  on the base layer  21  in the adhesive region D 5  (or the non-adhesive region D 2   a ), and the two second marks M 2  are printed by the thermal head  7  on the base layer  21  in the partly-adhesive region D 7 , specifically, the non-adhesive region D 7   a  (or the non-adhesive region D 6   b ). 
     As in the above-described case, positions of each of the first marks M 1  and the second marks M 2  in the first direction and the second direction are determined by control of the control circuit  2  for the thermal head  7  and the conveying roller  6 , and the two first marks M 1  and the two second marks M 2  are formed such that each of the two first marks M 1  and a corresponding one of the two second marks M 2  are arranged along the up and down direction in  FIG. 7A , i.e., the first direction. In this example, the first marks M 1  and the second marks M 2  have the same shape (square in this example). As illustrated in  FIG. 7A , the marks M 1 , M 2  are formed on opposite end portions of the print label L in the second direction, i.e., the left end region W 1  and the right end region W 3 . 
     Procedure of Attachment of Print Label to Wrapped Member 
       FIGS. 8A-9B  illustrate one example of a procedure of attachment of the print label L to the wrapped member in this case.  FIGS. 8A and 8B  illustrate a case of attaching the print label L to the wrapped member  302  having a relatively large diameter.  FIGS. 9A and 9B  illustrate a case of attaching the print label L to the wrapped member  302  having a relatively small diameter. In this example,  FIGS. 8A and 9A  illustrate one example of wrapping the print label L around the wrapped member  302  shaped like a circular cylinder or a cable and having a diameter 2r (or 2r′). 
     As illustrated in  FIGS. 8A and 9A , the separation layer  24  is first peeled off from the print label L having the above-described structure to expose the non-adhesive layer  23  and so on. While the print label L is constituted by the adhesive region D 5 , the non-adhesive region D 6   a , the non-adhesive region D 6   b , and the partly-adhesive region D 7  arranged in this order, the portions of the print label L in the adhesive region D 5 , the non-adhesive region D 6   a , and the non-adhesive region D 6   b  are then bent in a concave shape such that a portion of the print label L which had been in contact with the separation layer  24  (a right portion of the print label L in  FIGS. 8A and 9A ) is located on an inner side (not illustrated). 
     As illustrated in  FIGS. 8B and 9B , the wrapped member  302  is placed on an inner portion of the concave portion of the print label L, and the print label L is wrapped around the wrapped member  302  so as to form a cylindrical member surrounding the wrapped member  302 . Then, the adhesive layer  22  in the adhesive region D 5  as a part of a distal end portion of the print label L (noted that the adhesive layer  22  in the adhesive region D 5  serves as the sticking portion) is stuck to the non-adhesive layer  23  as the stuck portion in the non-adhesive region D 7   a  of the partly-adhesive region D 7  in the case illustrated in  FIG. 8B  and to the non-adhesive layer  23  as the stuck portion in the non-adhesive region D 6   b  and the non-adhesive region D 7   a  in the case illustrated in  FIG. 9B  (that is, the inner-sides sticking is performed). This sticking is performed such that each of the two first marks M 1  in the adhesive region D 5  and the corresponding one of the two second marks M 2  in the non-adhesive region D 7   a  are located at the same position when viewed in the right and left direction in  FIGS. 8B and 9B . In this state, the sum of the lengths L 6 , L 7 , L 8   a  of the non-adhesive layer  23  in the first direction is at least greater than or equal to the circumference of a circle 2πr, 2πr′ of the wrapped member  302 . As a result, the shape of the print label L is fixed by the sticking, and the print label L is wrapped around the wrapped member  302  without adhesive, whereby the print label L is rotatably attached to the wrapped member  302 . 
     Thereafter, the rest portion (the adhesive region D 7   b  in the example in  FIG. 8B  and the partly-adhesive region D 7  in the example in  FIG. 9B ) of the partly-adhesive region D 8  which is not used for surrounding the wrapped member  302  is wrapped around an outer circumferential portion of the print label L (not illustrated) so as to cover the cylindrical member such that the stuck portions of the print label L are folded into an inner circumferential side. The portion of the print label L in the adhesive region D 7   b  of the partly-adhesive region D 7  is stuck to the outer circumferential portion of the cylindrical member using adhesiveness of the adhesive layer  22 , and the attachment of the print label L to the wrapped member  302  is finished. 
     Case where Continuous Length Tape 
     The label creating apparatus  1  is capable of creating the print label L by using the print tape of the continuous type.  FIG. 10A  illustrates a structure of the print tape To of the continuous type. As illustrated in  FIG. 10A , the print tape To in this case does not have the half-cut regions HC as illustrated in  FIG. 2A  and is cut into a predetermined size by the cutters  9  based on control of the control circuit  2  in creation of the print label L. Thus, the print tape To does not have the non-label portion LB. The print tape To is divided into a plurality of label regions Lo (corresponding to the label portions LA in the above-described embodiment) by cut-planned lines CP along which the print tape To is to be cut by the cutters  9 . The label regions Lo are continuous to one another in the longitudinal direction of the print tape To. 
       FIG. 10B  is a plan view of the print tape T after the character strings R are printed on the respective label regions Lo. The character strings R representing “A01”, “A02”, “A03”, and so on are formed in order respectively on the label regions Lo as in the structure illustrated in  FIG. 2B , and the print tape T is cut by the cutters  9  along cutting lines FC (corresponding to the cut-planned lines CP) to create the print labels L. It is noted that  FIG. 10B  illustrates the print labels L in an unseparated state for easy understanding even though the print tape T has already been cut by the cutters  9 . 
     Function of Printing Mark on Portion Other than Opposite End Portions 
     The label creating apparatus  1  according to the present embodiment is capable of setting the number of the marks M 1 , M 2  in accordance with a second-direction dimension W of the print label L (see the axial-direction mark-position setter  409  and a number-of-marks calculator  410  which will be described below).  FIG. 11A  illustrates an example in which the mark M 1  and the mark M 2  are printed on the central region W 2  in addition to the marks M 1  and the marks M 2  printed on the opposite end regions of the print label L (i.e., the left end region W 1  and the right end region W 3 ) as illustrated in  FIG. 3A  by way of example.  FIG. 11B  illustrates a cross-sectional view taken along line XIB-XIB in  FIG. 11A .  FIG. 11B  corresponds to  FIG. 3B . In this case, as illustrated in  FIGS. 11A and 11B , the thermal head  7  and the conveying roller  6  are controlled by the control circuit  2  to print the three marks M 1  and the three marks M 2 . That is, in the case where it is assumed that the adhesive region D 1  is divided into the three regions in the second direction, the first marks M 1  are printed respectively on the left end region W 1  in the adhesive region D 1 , the central region W 2  in the adhesive region D 1 , and the right end region W 3  in the adhesive region D 1  such that a distance between the first mark M 1  in the left end region W 1  in the adhesive region D 1  and the first mark M 1  in the central region W 2  in the adhesive region D 1  is equal to a distance between the first mark M 1  in the central region W 2  in the adhesive region D 1  and the first mark M 1  in the right end region W 3  in the adhesive region D 1 . Likewise, it is assumed that the non-adhesive region D 3   a  is divided into the three regions in the second direction, the second marks M 2  are printed respectively on the left end region W 1  in the non-adhesive region D 3   a , the central region W 2  in the non-adhesive region D 3   a , and the right end region W 3  in the non-adhesive region D 3   a  such that a distance between the second mark M 2  in the left end region W 1  in the non-adhesive region D 3   a  and the second mark M 2  in the central region W 2  in the non-adhesive region D 3   a  is equal to a distance between the second mark M 2  in the central region W 2  in the non-adhesive region D 3   a  and the second mark M 2  in the right end region W 3  in the non-adhesive region D 3   a . As a result, even in the case of the print label L having a relatively large dimension in the second direction, the above-described positioning can be easily performed in the sticking. 
     Control Circuit 
     There will be next explained a configuration and a control procedure of the control circuit  2  for achieving the above-described functions.  FIG. 12  illustrates a functional configuration of the control circuit  2 . As illustrated in  FIG. 12 , the control circuit  2  functionally includes the controller  500 , an information obtainer  400 , a correction-information obtainer  405 , a length obtainer  406 , and a selection receiver  407 . The controller  500  includes a margin determiner  404 , the circumferential-direction mark-position setter  408 , the axial-direction mark-position setter  409 , and the number-of-marks calculator  410 . Functions of these elements will be described later in detail. 
     Control Procedure 
     There will be next explained a control procedure executed by the control circuit  2  (specifically, the CPU) with reference to the flow chart in  FIG. 13 . The flow in  FIG. 13  begins when the label creating apparatus  1  is turned on, for example. 
     At S 1 , the CPU of the control circuit  2  executes a print setting processing (which will be described later in detail) corresponding to print data, created based on the operation of the operation device  3 , for forming the character string R on the print tape To. 
     At S 5 , the CPU of the control circuit  2  outputs a control signal to the conveying roller  6  to draw the print tape To from the tape roll  10 A, that is, the CPU controls the conveying roller  6  to start conveying the print tape To. It is noted that when the CPU outputs a control signal in this specification, the CPU may output the control signal via a drive circuit, not illustrated. 
     The CPU of the control circuit  2  at S 10  determines whether the print tape To is conveyed by a predetermined amount and located at a print starting position. For example, this predetermined amount is a distance required for a distal end of the print tape To in the character-string print region RA to reach a position substantially opposed to the thermal head  7 . When the print tape To is not conveyed by the predetermined amount (S 10 : NO), the CPU repeats this processing. When the print tape To is conveyed by the predetermined amount (S 10 : YES), this flow goes to S 15 . 
     The CPU of the control circuit  2  at S 15  outputs a control signal to the thermal head  7  to start printing the character string R on the portion of the print tape To in the character-string print region RA conveyed by the conveying roller  6  and printing the marks M 1 , M 2  based on the print data, based on the settings (which will be described later in detail) set in the print setting processing at S 1 . As described above, the print tape To becomes the print tape T after this printing. 
     The CPU of the control circuit  2  at S 20  determines whether the printing of the character string R on the portion of the print tape To in the character-string print region RA by the thermal head  7  and the printing of the marks M 1 , M 2  by the thermal head  7  are completed. In other words, the CPU determines whether the print tape T has reached a print end position. When the printing of the character string R and the marks M 1 , M 2  is not completed (S 20 : NO), the CPU repeats this processing. When the printing of the character string R and the marks M 1 , M 2  are completed (S 20 : YES), this flow goes to S 25 . 
     The CPU of the control circuit  2  at S 25  outputs a control signal to the thermal head  7  to stop the printing on the character-string print region (the non-adhesive region D 2   b ) of the print tape To conveyed by the conveying roller  6 . 
     The CPU of the control circuit  2  at S 30  determines the print tape T on which the printing is performed by the thermal head  7  is located at a cuttable position. Specifically, in the case where the print tapes To, T having the structure illustrated in  FIGS. 2A and 2B , for example, the CPU determines whether the cutters  9  are opposed to the non-label portion LB located between the adjacent print labels L. In the print tapes To, T having the structure illustrated in  FIGS. 10A and 10B , for example, the CPU determines whether the cutters  9  are opposed to the cut-planned lines CP located between the adjacent print labels L. When the print tape T has not reached the cuttable position (S 30 : NO), the CPU repeats this processing. When the print tape T has reached the cuttable position, the cuttable position (S 30 : YES), this flow goes to S 35 . 
     The CPU of the control circuit  2  at S 35  outputs a control signal to the conveying roller  6  to stop feeding the print tape To from the tape roll  10 A. That is, the conveyance of the print tape To which is started at S 5  is stopped. 
     The CPU of the control circuit  2  at S 40  outputs a control signal to an actuator, not illustrated, (e.g., a solenoid) for driving the cutters  9  to cut the print tape T (specifically, the non-label portion LB or the cut-planned line CP between the print labels L). It is noted that in the case where the above-described cut lever is provided, this processing is omitted, and the CPU of the control circuit  2  waits for the print tape T to be cut based on the operation of the cutters  9  by the user via the cut lever after the stop of the conveyance at S 35 . This procedure in this flow thereafter ends. 
     Print Setting Processing 
     There will be next explained a detailed procedure of the print setting processing with reference to  FIG. 14 . 
     The procedure in  FIG. 14  begins with S 43  at which the information obtainer  400  of the control circuit  2  obtains outside-diameter relating information on the wrapped member  302  (the outside diameter of the wrapped member  302  or a module number, a type, or the like corresponding to the outside diameter) which is manually input via the operation device  3 , for example. 
     The margin determiner  404  of the control circuit  2  at S 45  executes a right-and-left-margin setting processing to determine the length of each of the margin regions RS in the second direction, based on the outside-diameter relating information obtained at S 43 . The right-and-left-margin setting processing will be described later in detail with reference to  FIG. 15 . 
     The circumferential-direction mark-position setter  408 , the axial-direction mark-position setter  409 , and the number-of-marks calculator  410  of the control circuit  2  at S 46  execute a mark setting processing for the marks M 1 , M 2 . This mark setting processing will be described later in detail with reference to  FIG. 17 . Upon completion of the processing at S 46 , this flow returns to S 5 . 
     Right-and-Left-Margin Setting Processing 
     There will be next explained a detailed procedure of the right-and-left-margin setting processing at S 45  with reference to  FIG. 15 . 
     In the right-and-left-margin setting processing illustrated in  FIG. 15 , the margin determiner  404  of the control circuit  2  at S 47  determines the length of each of the margin regions RS in the second direction, based on the outside-diameter relating information obtained at S 43 . This determination is performed based on a right-and-left-margin table stored in the memory  5  in advance. 
     Right-and-Left-Margin Table 
       FIG. 16  illustrates one example of the right-and-left-margin table. In  FIG. 16 , the dimension of each of the print tapes To, T in the widthwise direction is 50.8 mm by way of example. As illustrated in  FIG. 16 , the right-and-left-margin table stores a relationship between the outside-diameter relating information obtained at S 43  (the outside diameter of the wrapped member  302  in this example) and the length of each of the margin regions RS in the second direction. 
     As illustrated in  FIG. 16 , in the case where the outside diameter of the wrapped member  302  is 9.1 mm, the length of each of the margin regions RS is 1 mm. In the case where the outside diameter of the wrapped member  302  is 8.1 mm, the length of each of the margin regions RS is 1 mm. In the case where the outside diameter of the wrapped member  302  is 7.1 mm, the length of each of the margin regions RS is 1 mm. In the case where the outside diameter of the wrapped member  302  is 6.1 mm, the length of each of the margin regions RS is 1 mm. In the case where the outside diameter of the wrapped member  302  is 5.1 mm, the length of each of the margin regions RS is 2 mm. In the case where the outside diameter of the wrapped member  302  is 4.1 mm, the length of each of the margin regions RS is 2 mm. In this right-and-left-margin table, the length of each of the margin regions RS is greater in the case where the outside diameter of the wrapped member  302  is less than or equal to a predetermined value assumed in advance (6.0 mm in this example) than in the case where the outside diameter of the wrapped member  302  is greater than the predetermined value. 
     Upon completion of the processing at S 47 , this flow returns to S 46 . 
     Mark Setting Processing 
     There will be next explained a detailed procedure of the mark setting processing at S 47  with reference to  FIG. 17 . 
     The procedure of the mark setting processing in  FIG. 17  begins with S 51  at which the selection receiver  407  of the control circuit  2  accepts, via the operation device  3 , user&#39;s selection of whether the first marks M 1  and the second marks M 2  are to be printed. That is, in the present embodiment, the user can select whether the marks M 1 , M 2  are to be formed. 
     Then, the CPU of the control circuit  2  at S 55  determines whether user&#39;s selection of printing the first marks M 1  and the second marks M 2  is accepted at S 51 . When user&#39;s selection of printing the first marks M 1  and the second marks M 2  is accepted (S 55 : YES), this flow goes to S 60 . When user&#39;s selection of not printing the marks M 1 , M 2  is accepted (S 55 : NO), this procedure ends, and the flow returns to S 5  in  FIG. 13 . 
     The length obtainer  406  of the control circuit  2  at S 60  obtains the length of the printed print tape T (i.e., the print label L) in the second direction, which length is input by the user via the operation device  3 , for example. That is, in the present embodiment, in the case where the print tapes To, T illustrated in  FIG. 10  are used, the length of the print label L to be created in the second direction can be selected by the user. It is noted that, in the case where the print tapes To, T illustrated in  FIG. 2  are used, the length of the print label L in the second direction is as described above determined uniquely based on which print tape (To, T) is used (based on the half-cut region HC). Thus, the user inputs the length via the operation device  3  in this case. Alternatively, the CPU of the control circuit  2  may automatically detect the length based on a result of detection of the cartridge sensor CS. 
     The axial-direction mark-position setter  409  and the circumferential-direction mark-position setter  408  of the control circuit  2  at S 65  set positions of the first mark M 1  and the second mark M 2  (in the first direction and in the second direction) in each of the opposite end regions of the print label L, i.e., the left end region W 1  and the right end region W 3 . In the setting of the positions in the first direction, for example, in the case where the outside diameter of the wrapped member  302  is small (in other words, the wrapped member  302  is narrow), the CPU sets the distance between the two marks M 1 , M 2  in the up and down direction to a short distance, and in the case where the outside diameter of the wrapped member  302  is large (in other words, the wrapped member  302  is thick), the CPU sets the distance between the two marks M 1 , M 2  in the up and down direction, to a long distance. 
     The number-of-marks calculator  410  of the control circuit  2  at S 70  calculates the number N of the first marks M 1  and the second marks M 2  in the second direction, based on the length of the print label L obtained by the length obtainer  406  at S 60 . Specifically, in the case where it is assumed that the length of the print label L is defined as LL, and a predetermined set distance used when a mark or marks are printed in addition to the two marks is defined as p, the total number N of the first marks M 1  or the second marks M 2  (including the mark or marks to be added) is calculated by the following expression: N=(LL/p)+2. That is, the number of marks N is increased with increase in the length LL of the print label L, for example. 
     The CPU of the control circuit  2  at S 75  determines whether the total number N of the first marks M 1  (or the second marks M 2 ) which is calculated at S 70  is greater than or equal to three. When the total number N is greater than or equal to three (S 75 : YES), this flow goes to S 80 . When the total number N is less than three (S 75 : NO), this flow goes to S 85 . 
     The axial-direction mark-position setter  409  and the circumferential-direction mark-position setter  408  of the control circuit  2  at S 80  set positions of the added marks M 1 , M 2  (the marks M 1 , M 2  except the two marks whose positions are determined at S 65 ) in the first direction and in the second direction, such that all the three or more first marks M 1  or second marks M 2  are spaced apart evenly in the second direction. 
     The CPU of the control circuit  2  at S 85  outputs a display control signal to the display  4  based on a result of the setting at S 65  (or S 65  and S 80 ) such that the positions of all the marks M 1 , M 2  on the print tape T are previewed on a screen displayed on the display  4 , for example. 
     The correction-information obtainer  405  of the control circuit  2  at S 90  obtains correction information about correction (including no correction) of positions set for all of the marks M 1 , M 2 , which correction is performed by the user via the operation device  3  in response to the preview screen. That is, in the present embodiment, the user can correct a result of the setting at S 65  (or S 65  and S 80 ). 
     The CPU of the control circuit  2  at S 95  determines, based on the result of the obtainment at S 90 , whether the positions of the marks M 1 , M 2  in the first direction and in the second direction are corrected by the user. When the positions are corrected (S 95 : YES), this flow goes to S 100 . When the positions are not corrected (S 95 : NO), this procedure ends, and the flow returns to S 5  in  FIG. 13 . 
     The circumferential-direction mark-position setter  408  and the axial-direction mark-position setter  409  of the control circuit  2  at S 100 , based on the correction information obtained at S 90 , correct the positions of the marks M 1 , M 2  in the first direction and in the second direction, which positions are set at S 65  (or S 65  and S 80 ). Upon completion of this processing, this procedure ends, and the flow returns to S 5  in  FIG. 13 . 
     Effects in First Embodiment 
     In the first embodiment as described above, the control circuit  2  controls the conveying roller  6  and the thermal head  7  to print the first marks M 1  on the adhesive region D 1  (or the non-adhesive region D 2   a ) and print the second marks M 2  on the non-adhesive region D 3   a  of the partly-adhesive region D 3  such that each of the first marks M 1  and a corresponding one of the second marks M 2  are arranged in the first direction. In another structure, as described above, the control circuit  2  controls the conveying roller  6  and the thermal head  7  to print the first marks M 1  on the adhesive region D 5  and the second marks M 2  on the partly-adhesive region D 7  (or the non-adhesive region D 6   b ). With this configuration, this label creating apparatus  1  is capable of creating the print label L on which the first marks M 1  and the second marks M 2  are printed such that each of the first marks M 1  and a corresponding one of the second marks M 2  are arranged in the up and down direction. Also, the portions of the print label L are stuck to each other such that the same kind of marks are aligned as described above (see  FIGS. 4B, 4C, 8B, and 9B ). Accordingly, it is possible to prevent misalignment and skew of the print label L and stick the portions of the print label L to each other in a proper posture. In particular, it is possible to prevent the adhesive from being exposed or lying off the print label L due to the misalignment and skew in the structure having the adhesive layer  22  as described above. This prevents the exposed adhesive from adhering to a hand of the user when the user handles the print label L and prevents the wrapped print label L from adhering to the wrapped member  302  due to the exposed adhesive, which may make it difficult for the wrapped print label L to rotate. 
     In the first embodiment as described above, the print label L is attached to the wrapped member  302  by sticking the portions of the print label L in the adhesive region D 1  and the partly-adhesive region D 3  to each other to form the cylindrical member around the wrapped member  302 . Thus, an additional force such as a twisting of the wrapped member  302  is not applied to the print label L and the wrapped member  302  as in the conventional structure in which the print label L is wrapped around the wrapped member  302  and cut along the perforation. Also, since the misalignment and skew are reduced during attachment, the print label L can be easily rotated around the wrapped member  302 , thereby ensuring viewability from a desired angle. 
     In the present embodiment, the circumferential-direction mark-position setter  408  sets the positions of the marks M 1 , M 2  in the first direction, based on the outside diameter of the wrapped member  302  which is obtained by the information obtainer  400 . In the case where the outside diameter of the wrapped member  302  is small (in other words, the wrapped member  302  is narrow), the cylindrical member having the small diameter corresponding to the small outside diameter of the wrapped member  302  can be shaped by reducing the distance between the two marks M 1 , M 2  in the up and down direction. In the case where the outside diameter of the wrapped member  302  is large (in other words, the wrapped member  302  is thick), increasing the distance between the two marks M 1 , M 2  in the up and down direction can shape the cylindrical member having the large diameter corresponding to the large outside diameter of the wrapped member  302  and form an appropriate space between the cylindrical member and the wrapped member  302 . 
     In the first embodiment, the margin determiner  404  sets the length of each of the margin regions RS in the second direction, based on the outside diameter of the wrapped member  302  which is obtained by the information obtainer  400 . In this setting, as described above, in the case where the outside diameter of the wrapped member  302  is small, the lengths of the margin regions RS in the right and left direction are increased to increase the sizes of the margin regions RS. This configuration prevents the character string R (e.g., “A001”) formed in the character-string print region RA from being hidden by the first marks M 1  and the second marks M 2  during wrapping, thereby preventing reduction of the viewability of the character string R formed in the character-string print region RA. 
     In the first embodiment, the number-of-marks calculator  410  increases the number of the marks M 1 , M 2  with increase in the length of the print label L in the second direction. This configuration facilitates the sticking even in the case of the print label L elongated in the second direction. 
     Modifications of First Embodiment 
     While the first embodiment has been described above, it is to be understood that the disclosure is not limited to the details of the illustrated embodiment, but may be embodied with various changes and modifications, which may occur to those skilled in the art, without departing from the spirit and scope of the disclosure. There will be described modifications of the first embodiment. It is noted that the same reference numerals as used in the first embodiment are used to designate the corresponding elements of the modifications, and an explanation of which is simplified or dispensed with. 
     1.1. Case where First Mark is Printed on Print Tape in Advance 
       FIG. 18  illustrates a general structure of the label creating apparatus  1  according to the present modification.  FIG. 18  corresponds to  FIG. 1 .  FIGS. 19A and 19B  illustrate a structure of a print tape used in the present modification.  FIGS. 19A and 19B  respectively correspond to  FIGS. 2A and 2B . 
     In the present modification, as illustrated in  FIG. 19A , the first marks M 1  (each as one example of a print mark) are printed in advance on the print tape To at the same positions as those in the above-described embodiment. In this label creating apparatus  1 , as illustrated in  FIG. 18 , a well-known mark sensor MS is provided to optically detect positions of the first marks M 1  on the print tape To in the first direction and in the second direction (see broken-line arrows in  FIG. 18 ), for example. The mark sensor M 3  outputs a detection signal to the control circuit  2 . 
       FIG. 20  illustrates a configuration of the control circuit  2  in the present modification.  FIG. 20  corresponds to  FIG. 12 . In the present modification, as illustrated in  FIG. 20 , the controller  500  includes a mark-position detector  411  configured to detect positions of the marks M 1  and receive the detection signal output from the mark sensor M 3 . Based on the positions of the marks M 1  which are detected by the mark-position detector  411  based on the detection signal, the circumferential-direction mark-position setter  408  and the axial-direction mark-position setter  409  set positions of the marks M 2  in the first direction and in the second direction, and the character string R and the marks M 2  are printed as described above. As a result, as illustrated in  FIG. 19B , the print tape T with the second marks M 2  printed at the same positions as those in  FIG. 2B  is created. 
       FIG. 21  illustrates a detail of the mark setting processing executed in the present modification.  FIG. 21  corresponds to  FIG. 17 . In the present modification, as illustrated in  FIG. 21 , a processing at S 57  is provided between S 55  and S 60  in  FIG. 17 . 
     That is, the mark-position detector  411  of the control circuit  2  at S 57  detects the positions of the marks M 1  in the first direction and in the second direction based on a detection signal output from the mark sensor MS. At S 65  and S 80 , positions of the marks M 2  in the first direction and in the second direction are set with respect to the positions of the marks M 1  which are detected at S 57 . Processings other than these processings are substantially the same as those in  FIG. 17 , and an explanation of which is dispensed with. 
     The present modification also achieves the same effects as those in the above-described embodiment. 
     1.2. Case where Second Mark is Printed on Print Tape in Advance 
     The second marks M 2  may be printed on the print tape To in advance. That is, in this case, the second marks M 2  (each as another example of the print mark) are printed in advance on the print tape To at the same positions as those in the above-described embodiment though not illustrated. In this label creating apparatus  1 , as illustrated in  FIG. 18 , the above-described mark sensor MS is provided to output a detection signal to the mark-position detector  411  of the control circuit  2 . Based on the positions of the marks M 1  which are detected by the mark-position detector  411  based on the detection signal, the circumferential-direction mark-position setter  408  and the axial-direction mark-position setter  409  set positions of the marks M 1  in the first direction and in the second direction, and the character string R and the marks M 1  are printed as described above. As a result, as illustrated in  FIG. 19B , the print tape T with the first marks M 1  printed at the same positions as those in  FIG. 2B  is created. 
     The present modification also achieves the same effects as those in the above-described embodiment. 
     1.3. Case where Mark Setting is Performed by Operation Terminal 
     While the present disclosure is applied to the standalone label creating apparatus  1  capable of working alone, but the present disclosure is not limited to this configuration. That is, the above-described processings may be executed on an operation terminal (as one example of a terminal) that is connected to a label creating apparatus similar in configuration to the label creating apparatus described above such that information is transmittable and receivable between the operation terminal and the label creating apparatus. In this case, the operation terminal includes a CPU, an operation device, and a memory configured to store a printed-medium creating program. 
     That is, the CPU first executes a processing similar to the print setting processing at S 1  in  FIG. 13 , according to the printed-medium creating program. 
     The CPU then outputs print data (as one example of a control procedure) containing information about the print setting processing, to the label creating apparatus similar in configuration to the label creating apparatus described above. Upon reception of the output print data, the label creating apparatus executes processings similar to the processings at S 15 -S 40  in  FIG. 13 . These processings enable the CPU of the operation terminal to perform setting on the marks on the print label L which has been explained taking the standalone label creating apparatus  1 . 
     The present modification also achieves the same effects as those in the above-described embodiment. 
     Second Embodiment 
     There will be next explained a second embodiment. It is noted that the same reference numerals as used in the first embodiment and the modifications thereof are used to designate the corresponding elements of the second embodiment, and an explanation of which is simplified or dispensed with. 
     BACKGROUND 
     There will be explained a background of the present embodiment with reference to  FIGS. 22A-25B .  FIGS. 22A and 22B  respectively correspond to  FIGS. 3A and 3B .  FIG. 22A  is a plan view of a print label L.  FIG. 22B  is a cross-sectional view taken along line XXIIB-XXIIB in  FIG. 22A . 
     As illustrated in  FIGS. 22A and 22B , in this example, four lines of the character strings R respectively representing “A01”, “abcdef”, “ghijklm”, and “nopqrs” are formed on the printing background layer  25  in the non-adhesive region D 2   b . When the print label L is attached to a wrapped member, as illustrated in  FIGS. 23A-23C , as described above, the print label L is wrapped around the wrapped member  302  so as to form a cylindrical member surrounding the wrapped member  302 , and then the adhesive layer  22  in the adhesive region D 1  as a distal end portion of the print label L (noted that the adhesive layer  22  in the adhesive region D 1  serves as the sticking portion) is stuck to a portion of the adhesive layer  22  in the non-adhesive region D 3   a  of the partly-adhesive region D 3  (noted that the portion serves as the stuck portion) via the non-adhesive layer  23  (that is, the inner-sides sticking is performed). As a result, as illustrated in  FIG. 23C , the character strings R respectively representing “A01”, “abcdef”, “ghijklm”, and “nopqrs” on the printing background layer  25  are covered with a portion of the print label L in the adhesive region D 3   b  (noted that the enlarged view in  FIG. 23C  illustrates the printing background layer  25  viewed from a position nearest thereto inside the portion of the print label L in the adhesive region D 3   b ). However, since portions of the base layer  21  and the adhesive layer  22  in the adhesive region D 3   b  are transparent, the character strings R are visually recognizable. In  FIG. 23 , the printing background layer  25  and the character strings R are indicated in manners different from that of the other layers for clarification of the layers. Specifically, the printing background layer  25  is indicated by the bold broken line, and the character strings R are indicated by the broken lines. This manner of illustration is used in other figures. 
     Inconvenience in the Case of Wrapped Member of Small Diameter 
       FIGS. 24A and 24B  illustrate one example in which the print label L is attached to the wrapped member  302  having an outside diameter less than that of the wrapped member  302  illustrated in  FIGS. 23A-23C .  FIGS. 24A and 24B  respectively correspond to  FIGS. 23B and 23C . In this case, as a result of the wrapping in the inner-sides sticking (in which the rest portion due to the inner-sides sticking is folded and wrapped around the outer circumferential portion), as illustrated in  FIG. 24B , the folded printing background layer  25  may cover the character strings R so as to make it impossible or difficult to visually recognize the character strings R. In this example, as illustrated in the enlarged view in  FIG. 24B  (noted that the enlarged view in  FIG. 24B  illustrates the printing background layer  25  viewed from a position nearest thereto inside the portion of the print label L in the adhesive region D 3   b ), the character strings R respectively representing “A01” and “abcdef” are not visually recognized due to the printing background layer  25  among the character strings R respectively representing “A01”, “abcdef”, “ghijklm”, and “nopqrs”. 
     Inconvenience in the Case of Wrapped Member of Large Diameter 
       FIGS. 25A and 25B  illustrate one example in which the print label L is attached to the wrapped member  302  having an outside diameter greater than that of the wrapped member  302  illustrated in  FIGS. 23A-23C .  FIGS. 25A and 25B  respectively correspond to  FIGS. 23B and 23C . 
     Ideally, as described in  FIGS. 23A-23C , the character strings R formed on the printing background layer  25  are covered with and protected by the transparent base layer  21  in the adhesive region D 3   b , which is wrapped on an outer circumferential portion of the printing background layer  25 , so as to ensure viewability of the character strings R, thereby preventing the character strings R from being soiled or faded. 
     However, in the case illustrated in  FIGS. 25A and 25B , some of the character strings R (“ghijklm” and “nopqrs” among “A01”, “abcdef”, “ghijklm”, and “nopqrs” in this example) are not covered with the base layer  21  and are exposed (see the enlarged view in  FIG. 25B ). That is, it is impossible to cover this portion with the transparent base layer  21  for protection. 
     Overview of Technique in Present Embodiment 
     To solve this problem, in this second embodiment, in the case where the outside diameter of the wrapped member  302  is small as described above, for example, the character strings R are printed on one-side portion of the print label L in the circumferential direction of the wrapped member  302  (in the direction in which the print label L is wrapped), thereby preventing the character strings R from being covered with the printing background layer  25 , thereby reducing an amount of lowering of the viewability. Specifically, a limitation in the first direction is imposed on the character-string print region RA set on the portion of the printing background layer  25  in the non-adhesive region D 2   b  (for example, a limitation is imposed on the length of the character-string print region RA in the first direction or on positions of upper and lower ends of the character-string print region RA in the first direction), and the thermal head  7  is allowed to form the character strings R on the limited character-string print region RA. In this respect, the character-string print region RA may be hereinafter referred to as “character-string printable region RA”. In the present embodiment, since the margin regions RS are not always set (or set to regions having the fixed width), the following explanation omits illustration and explanation of the margin regions RS. 
     That is, in the example illustrated in  FIGS. 26A and 26B , the character-string printable region RA is set below a center line m extending through a center of the portion of the printing background layer  25  in the first direction in the non-adhesive region D 2   b  in  FIGS. 26A and 26B  if possible. In other words, the character-string printable region RA is set on one side of the center line m in the first direction. That is, the position of the upper end of the character-string printable region RA is located below the center line m in  FIGS. 26A and 26B , which reduces the dimension (height) of the character-string printable region RA in the up and down direction in  FIGS. 26A and 26B  (in the first direction). 
     The maximum values are set for the number of lines and the font size of the character strings R printable on the character-string printable region RA, in other words, the number of lines and the font size are limited. In this example, the font size of the character strings R is made smaller than those in the example in  FIG. 22 , and the number of lines on the character-string printable region RA is reduced from four to two, so that not the four character strings R respectively representing “A01”, “abcdef”, “ghijklm”, and “nopqrs” but only the two character strings R respectively representing “A01” and “abcdef” are printed. 
     As a result, as illustrated in  FIGS. 27A and 27B  respectively corresponding to  FIGS. 24A and 24B , since the character-string printable region RA is displaced as described above even after the print label L is attached to the wrapped member  302 , the printing background layer  25  does not cover all the character strings R (“A01” and “abcdef”), ensuring the viewability. 
     In the case where the outside diameter of the wrapped member  302  is large, on the other hand, the character strings R are printed on the other-side portion of the print label L in the circumferential direction of the wrapped member  302 , whereby the transparent region reliably covers the printing background layer  25 , thereby ensuring the viewability and preventing the character strings R from being soiled or faded. Specifically, as illustrated in  FIGS. 28A and 28B , the character-string printable region RA is set above the center line m extending through the center of the portion of the printing background layer  25  in the first direction in the non-adhesive region D 2   b  in  FIGS. 28A and 28B . In other words, the character-string printable region RA is set on the other side of the center line m in the first direction. That is, the position of the lower end of the character-string printable region RA is located above the center line m in  FIGS. 28A and 28B , which reduces the height of the character-string printable region RA. 
     As in the above-described case, the maximum values are set for the number of lines and the font size of the character strings R printable on the character-string printable region RA, in other words, the number of lines and the font size are limited. In this example, the font size of the character strings R is made smaller than those in the example in  FIG. 22 , and the number of lines on the character-string printable region RA is reduced from four to two, so that not the four character strings R respectively representing “A01”, “abcdef”, “ghijklm”, and “nopqrs” but only the two character strings R respectively representing “A01” and “abcdef” are printed. 
     As a result, as illustrated in  FIGS. 29A and 29B  respectively corresponding to  FIGS. 24A and 24B , since the character-string printable region RA is displaced as described above even after the print label L is attached to the wrapped member  302 , all the character strings R (“A01” and “abcdef”) are covered with the base layer  21 , thereby ensuring the viewability and protecting the character strings R. 
     Center Alignment 
     There will be next explained other examples of the technique in the present embodiment with reference to  FIGS. 30A-31B . In these examples, the center line of the character-string printable region RA in the first direction is aligned with the center line m as in the case in  FIG. 22  (center alignment). 
     In the example illustrated in  FIG. 30 , not the character strings R respectively representing “A01”, “abcdef”, “ghijklm”, and “nopqrs” but only the character strings R respectively representing “A01” and “abcdef” are printed without change of the font size, thereby reducing the height of the character-string printable region RA when compared with the example in  FIG. 22 . In the example illustrated in  FIG. 31 , the font size of each character of the character strings R respectively representing “A01”, “abcdef”, “ghijklm”, and “nopqrs” is made smaller than in the example in  FIG. 22 , thereby reducing the height of the character-string printable region RA when compared with the example in  FIG. 22 . 
     In any of these cases, the positions of the lower and upper ends of the character-string printable region RA are displaced toward one side or the other side in the circumferential direction when compared with the case in  FIG. 22 , thereby achieving the same effects as those described above. 
     Control Circuit 
     There will be next explained a configuration and a control procedure of the control circuit  2  for achieving the above-described functions in the present embodiment.  FIG. 32  illustrates a functional configuration of the control circuit  2 . In the present embodiment, as illustrated in  FIG. 32 , the control circuit  2  functionally includes only the controller  500  and the information obtainer  400 . The controller  500  includes only a region setter  401 . Functions of these elements will be described later in detail. 
     There will be next explained a procedure of the print setting processing executed by the control circuit  2  in the second embodiment. 
     Detailed Procedure of Print Setting Processing 
       FIG. 33  illustrates the print setting processing executed in the present embodiment.  FIG. 33  corresponds to  FIG. 14 . In the present embodiment, as illustrated in  FIG. 33 , a processing at S 44  is provided instead of the processings at S 45  and S 46  in  FIG. 14 . 
     That is, the flow goes to S 44  after the information obtainer  400  obtains the outside-diameter relating information at S 43  as in the first embodiment. 
     The region setter  401  of the control circuit  2  at S 44  executes a character-string-printable-region setting processing for adjustably setting the character-string printable region RA based on the outside-diameter relating information obtained at S 43 . Upon completion of this processing, this procedure ends, and the flow returns to S 5  in  FIG. 13 . 
     Setting of Character-String Printable Region 
     There will be next explained a procedure of the character-string-printable-region setting processing with reference to  FIG. 34 . 
     The procedure in  FIG. 34  begins with S 101  at which the CPU of the control circuit  2  receives alignment reference position information input by the user via the operation device  3 . The alignment reference position information indicates whether setting on the character-string printable region RA is the above-described center alignment (see  FIGS. 30 and 31 ) or another type of alignment (see  FIGS. 26 and 28 ). That is, in the present embodiment, the user is allowed to select the type of alignment to any of the center alignment and the above-described normal alignment. 
     The CPU of the control circuit  2  at S 103  determines whether selection indicating use of the center alignment is received at S 101 . When selection of the center alignment is not received, that is, when selection of the above-described normal alignment is received (S 103 : NO), this flow goes to S 105 . When selection of the center alignment is received (S 103 : YES), this flow goes to S 117 . 
     At S 105 , S 108 , S 111 , and S 114 , the region setter  401  of the control circuit  2  sets, based on the outside-diameter relating information obtained at S 43  (the outside diameter in the above-described example), the position of the lower end of the character-string printable region RA, the height of the character-string printable region RA, the maximum number of lines in the character-string printable region RA, and the maximum character size (font size) in the character-string printable region RA. This setting is performed with reference to the character-string-printable-region table stored in the memory  5  (as one example of a first storage). 
     Character-String-Printable-Region Table 
       FIG. 35  illustrates one example of the character-string-printable-region table. In  FIG. 35 , the dimension of each of the print tapes To, T in the widthwise direction is 50.8 mm by way of example. As illustrated in  FIG. 35 , the character-string-printable-region table stores a relationship among the outside-diameter relating information obtained at S 43  (the outside diameter of the wrapped member  302  in this example), the position of the lower end of the corresponding character-string printable region RA, the height of the character-string printable region RA, the maximum number of lines of the character strings R in the character-string printable region RA, and the maximum character size of each character of the character strings R in the character-string printable region RA. It is noted that the position of the lower end of the character-string printable region RA is represented by a distance (mm) from a reference position (0 mm) that is set at one end of the print label L in the first direction (e.g., a lower end of the adhesive region D 3   b  in the case of the print label L in  FIG. 22A ). 
     In this table, as illustrated in  FIG. 35 , in the case where the outside diameter of the wrapped member  302  is 9.1 mm, the position of the lower end of the character-string printable region RA is 29.6 mm, the height of the character-string printable region RA is 6.4 mm, the maximum number of lines in the character-string printable region RA is two, and the maximum character size in the character-string printable region RA is 17 pt, for example. Likewise, in the case where the outside diameter of the wrapped member  302  is 8.1 mm, the position of the lower end of the character-string printable region RA is 26.4 mm, the height of the character-string printable region RA is 9.6 mm, the maximum number of lines in the character-string printable region RA is three, and the maximum character size in the character-string printable region RA is 26 pt, for example. Likewise, in the case where the outside diameter of the wrapped member  302  is 7.1 mm, the position of the lower end of the character-string printable region RA is 23.3 mm, the height of the character-string printable region RA is 12.7 mm, the maximum number of lines in the character-string printable region RA is four, and the maximum character size in the character-string printable region RA is 34 pt, for example. Likewise, in the case where the outside diameter of the wrapped member  302  is 6.1 mm, the position of the lower end of the character-string printable region RA is 23.3 mm, the height of the character-string printable region RA is 12.7 mm, the maximum number of lines in the character-string printable region RA is four, and the maximum character size in the character-string printable region RA is 34 pt, for example. Likewise, in the case where the outside diameter of the wrapped member  302  is 5.1 mm, the position of the lower end of the character-string printable region RA is 23.3 mm, the height of the character-string printable region RA is 12.7 mm, the maximum number of lines in the character-string printable region RA is four, and the maximum character size in the character-string printable region RA is 34 pt, for example. Likewise, in the case where the outside diameter of the wrapped member  302  is 4.1 mm, the position of the lower end of the character-string printable region RA is 23.3 mm, the height of the character-string printable region RA is 12.7 mm, the maximum number of lines in the character-string printable region RA is four, and the maximum character size in the character-string printable region RA is 34 pt, for example. Likewise, in the case where the outside diameter of the wrapped member  302  is 3.1 mm, the position of the lower end of the character-string printable region RA is 23.3 mm, the height of the character-string printable region RA is 9.6 mm, the maximum number of lines in the character-string printable region RA is three, and the maximum character size in the character-string printable region RA is 26 pt, for example. Likewise, in the case where the outside diameter of the wrapped member  302  is 2.1 mm, the position of the lower end of the character-string printable region RA is 23.3 mm, the height of the character-string printable region RA is 6.4 mm, the maximum number of lines in the character-string printable region RA is two, and the maximum character size in the character-string printable region RA is 17 pt, for example. 
     According to the settings in the character-string-printable-region table, the CPU executes control for adjustably setting, based on the outside diameter of the wrapped member  302 , an other-side end of the character-string printable region RA in the first direction (an upper end thereof in  FIG. 26A  which corresponds to a position of a second end portion) and a one-side end of the character-string printable region RA in the first direction (a lower end thereof in  FIG. 26A  which corresponds to a position of a first end portion). Specifically, for example, the CPU executes control such that the other-side end of the character-string printable region RA in the first direction (the upper end thereof in  FIG. 26A ) is situated nearer to the one side in the first direction (the lower side in  FIG. 26A ) in the case where the outside diameter of the wrapped member  302  is less than a first predetermined diameter (e.g., 4.1 mm) than in the case where the outside diameter of the wrapped member  302  is greater than or equal to the first predetermined diameter and less than or equal to a second predetermined diameter (e.g., 7.1 mm) and such that the one-side end of the character-string printable region RA in the first direction (i.e., the lower end thereof in  FIG. 26A ) is situated nearer to the other side in the first direction (the upper side in  FIG. 26A ) in the case where the outside diameter of the wrapped member  302  is greater than the second predetermined diameter (e.g., 7.1 mm) than in the case where the outside diameter of the wrapped member  302  is greater than or equal to the first predetermined diameter and less than or equal to the second predetermined diameter (e.g., 7.1 mm). 
     In this control, the one-side end of the character-string printable region RA in the first direction (i.e., the lower end thereof in  FIG. 26A ) is situated at the same position in the first direction between the case where the outside diameter of the wrapped member  302  is less than the first predetermined diameter (e.g., 4.1 mm) and the case where the outside diameter of the wrapped member  302  is greater than or equal to the first predetermined diameter and less than or equal to the second predetermined diameter (e.g., 7.1 mm). Likewise, the other-side end of the character-string printable region RA in the first direction (the upper end thereof in  FIG. 26A ) is situated at the same position in the first direction between the case where the outside diameter of the wrapped member  302  is greater than the second predetermined diameter (e.g., 7.1 mm) and the case where the outside diameter of the wrapped member  302  is greater than or equal to the first predetermined diameter and less than or equal to the second predetermined diameter (e.g., 7.1 mm). 
     Also, the CPU executes control so as to make the maximum number of lines R in the character-string printable region RA less in the case where the outside diameter of the wrapped member  302  is less than the first predetermined diameter (e.g., 4.1 mm) than in the case where the outside diameter of the wrapped member  302  is greater than or equal to the first predetermined diameter and less than or equal to the second predetermined diameter (e.g., 7.1 mm) and so as to make the maximum number of lines R in the character-string printable region RA less in the case where the outside diameter of the wrapped member  302  is greater than the second predetermined diameter (e.g., 7.1 mm) than in the case where the outside diameter of the wrapped member  302  is greater than or equal to the first predetermined diameter (e.g., 4.1 mm) and less than or equal to the second predetermined diameter (e.g., 7.1 mm), for example. 
     Also, the CPU executes control so as to make the maximum character size in the character-string printable region RA less in the case where the outside diameter of the wrapped member  302  is less than the first predetermined diameter (e.g., 4.1 mm) than in the case where the outside diameter of the wrapped member  302  is greater than or equal to the first predetermined diameter and less than or equal to the second predetermined diameter (e.g., 7.1 mm) and so as to make the maximum character size in the character-string printable region RA less in the case where the outside diameter of the wrapped member  302  is greater than the second predetermined diameter (e.g., 7.1 mm) than in the case where the outside diameter of the wrapped member  302  is greater than or equal to the first predetermined diameter (e.g., 4.1 mm) and less than or equal to the second predetermined diameter (e.g., 7.1 mm), for example. 
     When the processings at S 105 -S 114  are finished as described above, this procedure ends, and the flow returns to S 5  in  FIG. 13 . 
     When the CPU at S 103  determines that selection of the center alignment is received, the region setter  401  of the control circuit  2  at S 117  and S 120  sets the maximum number of lines in the character-string printable region RA and the maximum character size (font size) in the character-string printable region RA based on the outside-diameter relating information obtained at S 43 . These settings are respectively performed with reference to a maximum-number-of-lines table and a maximum-character-size table stored in the memory  5  (as one example of second and third storages). 
     Maximum-Number-of-Lines Table 
       FIG. 36  illustrates one example of the maximum-number-of-lines table. In  FIG. 36 , the dimension of each of the print tapes To, T in the widthwise direction is 50.8 mm by way of example. As illustrated in  FIG. 36 , the maximum-number-of-lines table stores a relationship between the outside-diameter relating information obtained at S 43  (the outside diameter of the wrapped member  302  in this example) and the maximum number of lines of the character strings R in the character-string printable region RA. 
     In this table, for example, in the case where the outside diameter of the wrapped member  302  is 9.1 mm, the maximum number of lines in the character-string printable region RA is not set (that is, printing is not permitted). In the case where the outside diameter of the wrapped member  302  is 8.1 mm, the maximum number of lines in the character-string printable region RA is two. In the case where the outside diameter of the wrapped member  302  is 7.1 mm, the maximum number of lines in the character-string printable region RA is four. In the case where the outside diameter of the wrapped member  302  is 6.1 mm, the maximum number of lines in the character-string printable region RA is four. In the case where the outside diameter of the wrapped member  302  is 5.1 mm, the maximum number of lines in the character-string printable region RA is four. In the case where the outside diameter of the wrapped member  302  is 4.1 mm, the maximum number of lines in the character-string printable region RA is four. In the case where the outside diameter of the wrapped member  302  is 3.1 mm, the maximum number of lines in the character-string printable region RA is two. In the case where the outside diameter of the wrapped member  302  is 9.1 mm, the maximum number of lines in the character-string printable region RA is not set (that is, printing is not permitted). 
     Maximum-Character-Size Table 
       FIG. 37  illustrates one example of the maximum-character-size table. In  FIG. 37 , the dimension of each of the print tapes To, T in the widthwise direction is 50.8 mm by way of example. As illustrated in  FIG. 37 , the maximum-character-size table stores a relationship between the outside-diameter relating information obtained at S 43  (the outside diameter of the wrapped member  302  in this example) and the maximum character size (font size) of each character of the character strings R in the character-string printable region RA. 
     In this table, for example, in the case where the outside diameter of the wrapped member  302  is 9.1 mm, the maximum character size in the character-string printable region RA is not set (that is, printing is not permitted). In the case where the outside diameter of the wrapped member  302  is 8.1 mm, the maximum character size in the character-string printable region RA is 18 pt. In the case where the outside diameter of the wrapped member  302  is 7.1 mm, the maximum character size in the character-string printable region RA is 34 pt. In the case where the outside diameter of the wrapped member  302  is 6.1 mm, the maximum character size in the character-string printable region RA is 34 pt. In the case where the outside diameter of the wrapped member  302  is 5.1 mm, the maximum character size in the character-string printable region RA is 34 pt. In the case where the outside diameter of the wrapped member  302  is 4.1 mm, the maximum character size in the character-string printable region RA is 34 pt. In the case where the outside diameter of the wrapped member  302  is 3.1 mm, the maximum character size in the character-string printable region RA is 18 pt. In the case where the outside diameter of the wrapped member  302  is 2.1 mm, the maximum character size in the character-string printable region RA is not set (that is, printing is not permitted). 
     Since the center alignment is employed in this case, though not specified in the table, the region setter  401  of the control circuit  2  sets a position (center position) of the center line m of the printing background layer  25  (in other words, the center line of the character-string printable region RA) to the same position in the first direction between the case where the outside diameter of the wrapped member  302  is less than the first predetermined diameter (e.g., 4.1 mm) and the case where the outside diameter of the wrapped member  302  is greater than or equal to the first predetermined diameter and less than or equal to the second predetermined diameter (e.g., 7.1 mm). Also, the region setter  401  of the control circuit  2  sets the center line m to the same position in the first direction between the case where the outside diameter of the wrapped member  302  is greater than the second predetermined diameter (e.g., 7.1 mm) and the case where the outside diameter of the wrapped member  302  is greater than or equal to the first predetermined diameter (e.g., 4.1 mm) and less than or equal to the second predetermined diameter (e.g., 7.1 mm). 
     When the processings at S 117  and S 120  are finished as described above, this procedure ends, and the flow returns to S 5  in  FIG. 13 . It is noted that both of the setting for the maximum number of lines at S 117  and the setting for the maximum character size at S 120  are not necessarily executed, and the CPU may execute one of these processings. 
     Effects in Second Embodiment 
     In the second embodiment as described above, the character-string printable region RA is adjustably set based on the outside-diameter relating information on the wrapped member  302 . As a result, in the case where the outside diameter of the wrapped member  302  is small, for example, the character-string printable region RA is set to a position nearer to the one side in the first direction (the lower side in  FIG. 26 ), and in the case of the center alignment, the height of the character-string printable region RA is reduced with respect to the center line m, thereby preventing the character strings R from being covered with the printing background layer  25  as illustrated in  FIG. 24 , resulting in reduction in an amount of lowering of the viewability. Also, in the case where the outside diameter of the wrapped member  302  is large, for example, the character-string printable region RA is set to a position nearer to the other side in the first direction (the upper side in  FIG. 28 ), and in the case of the center alignment, the height of the character-string printable region RA is reduced with respect to the center line m, thereby reliably covering the character strings R printed on the printing background layer  25  with the transparent base layer  21  unlike the case in  FIG. 25 , thereby ensuring the viewability and preventing the character strings R from being soiled or faded. In the present embodiment as described above, it is possible to fill user&#39;s need for the character strings R to improve a convenience to the user. 
     Modifications of Second Embodiment 
     While the second embodiment has been described above, it is to be understood that the disclosure is not limited to the details of the illustrated embodiment, but may be embodied with various changes and modifications, which may occur to those skilled in the art, without departing from the spirit and scope of the disclosure. There will be described modifications of the second embodiment. It is noted that the same reference numerals as used in the first and second embodiments and the modifications of the first embodiment are used to designate the corresponding elements of the modifications, and an explanation of which is simplified or dispensed with. 
     That is, while the character-string printable region RA is adjustably set (that is, the height and the position of the character-string printable region RA are changeable) with respect to the structure illustrated in  FIG. 22  in the second embodiment, the present disclosure is not limited to this configuration. In a modification, the character strings R in the character-string printable region RA may be situated nearer to the one side or the other side in the first direction, with the character-string printable region RA being fixed. The modification will be next explained with reference to  FIGS. 38A-47 . 
       FIGS. 38A-38C  illustrate a structure and an attachment manner of the print label L which are precondition for the present modification. As illustrated in  FIG. 38D , in this example, two lines of the character strings R respectively representing “B01” and “xxyyzz” are formed on the printing background layer  25  in the non-adhesive region D 2   b.    
     When the print label L is attached to a wrapped member, as described above, the print label L is wrapped around the wrapped member  302  so as to form a cylindrical member surrounding the wrapped member  302 , and then the adhesive layer  22  in the adhesive region D 1  as a distal end portion of the print label L (noted that the adhesive layer  22  in the adhesive region D 1  serves as the sticking portion) is stuck to a portion of the adhesive layer  22  in the non-adhesive region D 3   a  of the partly-adhesive region D 3  (noted that the portion serves as the stuck portion) via the non-adhesive layer  23  (that is, the inner-sides sticking is performed). As a result, as illustrated in  FIG. 38C , the character strings R respectively representing “B01” and “xxyyzz” on the printing background layer  25  are covered with a portion of the print label L in the adhesive region D 3   b  (noted that the enlarged view in  FIG. 38C  illustrates the printing background layer  25  viewed from a position nearest thereto inside the portion of the print label L in the adhesive region D 3   b ). However, since portions of the base layer  21  and the adhesive layer  22  in the adhesive region D 3   b  are transparent, the character strings R are visually recognizable. 
     Inconvenience in the Case of Wrapped Member of Small Diameter 
       FIGS. 39A and 39B  illustrate one example in which the print label L is attached to the wrapped member  302  having an outside diameter less than that of the wrapped member  302  illustrated in  FIGS. 38A-38C .  FIGS. 39A and 39B  respectively correspond to  FIGS. 39A and 39B . In this case, as a result of the wrapping in the inner-sides sticking (in which the rest portion due to the inner-sides sticking is folded and wrapped around the outer circumferential portion), as illustrated in  FIG. 39B , the folded printing background layer  25  may cover the character strings R so as to make it impossible or difficult to visually recognize the character strings R. In this example, as illustrated in the enlarged view in  FIG. 39B  (noted that the enlarged view in  FIG. 39B  illustrates the printing background layer  25  viewed from a position nearest thereto inside the portion of the print label L in the adhesive region D 3   b ), the character string R representing “B01” is not visually recognized due to the printing background layer  25  among the character strings R respectively representing “B01” and “xxyyzz”. 
     Inconvenience in the Case of Wrapped Member of Large Diameter 
       FIGS. 40A and 40B  illustrate one example in which the print label L is attached to the wrapped member  302  having an outside diameter greater than that of the wrapped member  302  illustrated in  FIGS. 38A-38C .  FIGS. 40A and 40B  respectively correspond to  FIGS. 38B and 38C . 
     Ideally, as described in  FIG. 38A-38C , the character strings R formed on the printing background layer  25  are covered with and protected by the transparent base layer  21  in the adhesive region D 3   b , which is wrapped on an outer circumferential portion of the printing background layer  25 , so as to ensure viewability of the character strings R, thereby preventing the character strings R from being soiled or faded. 
     However, in the case illustrated in  FIGS. 40A and 40B , one of the character strings R (“xxyyzz” of “B01” and “xxyyzz” in this example) is not covered with the base layer  21  and is exposed (see the enlarged view in  FIG. 40B ). That is, it is impossible to cover this portion with the transparent base layer  21  for protection. 
     Overview of Technique in Present Embodiment 
     To solve this problem, in the present modification, in the case where the outside diameter of the wrapped member  302  is small as described above, for example, as illustrated in  FIGS. 41A and 41B , the position of the entire character strings R is located nearer to the lower side in  FIGS. 41A and 41B  than in the case in  FIGS. 40A and 40B , with no change of the position of the character-string printable region RA. It is noted that the number of lines and the font size of the character strings R printable on the character-string printable region RA are not changed, either. As a result of this arrangement, in the illustrated example, since the character-string printable region RA is displaced as described above even after the print label L is attached to the wrapped member  302 , the printing background layer  25  does not cover all the character strings R (“B01” and “xxyyzz”), ensuring the viewability. It should be noted that no problems arise in the case of the character strings R of two lines as in this example, but in the case of the character strings R of three or more lines, the first and second character strings R from the bottom are located outside the printing background layer  25 , but the other character strings R are covered with the printing background layer  25 . Accordingly, the present modification is effective in particular in the case where the number of lines is small and in the case where the height of the region to be printed is low. 
       FIGS. 42A and 42B  illustrate the structure of the print label L in this case.  FIGS. 42A and 42B  respectively correspond to  FIGS. 26A and 26B . As illustrated in  FIGS. 42A and 42B , the entire character strings R are arranged in the character-string printable region RA at positions located below the center line m in  FIG. 42A  as near as possible to the one-side end of the character-string printable region RA in the first direction. 
     On the other hand, in the case where the outside diameter of the wrapped member  302  is large, as illustrated in  FIGS. 43A and 43B , the position of the entire character strings R is located nearer to the upper side in  FIGS. 43A and 43B  than in the case in  FIGS. 40A and 40B , with no change of the position of the character-string printable region RA. As in the above-described case, the number of lines and the font size of the character strings R printable on the character-string printable region RA are not changed, either. As a result of this arrangement, as illustrated in  FIGS. 43A  and  43 B, since the character-string printable region RA is displaced as described above even after the print label L is attached to the wrapped member  302 , all the character strings R (“B01” and “xxyyzz”) are reliably covered with the transparent base layer  21 , thereby ensuring the viewability and preventing the character strings R from being soiled or faded. It should be noted that no problems arise in the case of the character strings R of two lines as in this example, but in the case of the character strings R of three or more lines, the first and second character strings R from the top are covered with the base layer  21 , but the other character strings R are exposed without being covered with the base layer  21 . Accordingly, the present modification is effective in particular in the case where the number of lines is small and in the case where the height of the region to be printed is low. 
       FIGS. 44A and 44B  illustrate the structure of the print label L in this case.  FIGS. 44A and 44B  respectively correspond to  FIGS. 38A and 38B . As illustrated in  FIGS. 44A and 44B , the entire character strings R are arranged in the character-string printable region RA at positions located above the center line m in  FIG. 44A  as near as possible to the other-side end of the character-string printable region RA in the first direction. 
       FIG. 45  illustrates a configuration of the control circuit  2  in the present modification.  FIG. 45  corresponds to  FIG. 32 . In the present modification, as illustrated in  FIG. 45 , the controller  500  includes a print-position setter  414  instead of the region setter  401 . This print-position setter  414  sets positional alignment of the character strings R in the portion of the printing background layer  25  in the character-string printable region RA, based on the outside-diameter relating information obtained from the information obtainer  400 . This setting is performed with reference to a character layout table stored in advance in the memory  5  (as one example of a fourth storage), for example. 
     Character Layout Table 
       FIG. 46  illustrates one example of the character layout table. In  FIG. 46 , the dimension of each of the print tapes To, T in the widthwise direction is 50.8 mm by way of example. As illustrated in  FIG. 46 , the character layout table stores a relationship between the outside-diameter relating information obtained at S 43  (the outside diameter of the wrapped member  302  in this example) and positional alignment of the character strings R. 
     In this table, for example, in the case where the outside diameter of the wrapped member  302  is 9.1 mm, the positional alignment of the character strings R is top alignment corresponding to alignment toward the other side in the first direction. In the case where the outside diameter of the wrapped member  302  is 8.1 mm, the positional alignment of the character strings R is the top alignment corresponding to the alignment toward the other side in the first direction. In the case where the outside diameter of the wrapped member  302  is 7.1 mm, the positional alignment of the character strings R is not the top alignment or bottom alignment, which will be described below, but center alignment (equivalent to the above-described center alignment). In the case where the outside diameter of the wrapped member  302  is 6.1 mm, the positional alignment of the character strings R is the center alignment. In the case where the outside diameter of the wrapped member  302  is 5.1 mm, the positional alignment of the character strings R is the center alignment. In the case where the outside diameter of the wrapped member  302  is 4.1 mm, the positional alignment of the character strings R is the center alignment. In the case where the outside diameter of the wrapped member  302  is 3.1 mm, the positional alignment of the character strings R is the bottom alignment corresponding to alignment toward the one side in the first direction. In the case where the outside diameter of the wrapped member  302  is 2.1 mm, the positional alignment of the character strings R is the bottom alignment. 
       FIG. 47  illustrates a detail of a mark setting processing executed by the mark-position detector  411  with reference to the character layout table in the present modification.  FIG. 47  corresponds to  FIG. 34 . 
     In the present modification, the procedure in  FIG. 47  begins with S 130  at which the print-position setter  414  of the control circuit  2  at S 130  determines, based on the outside-diameter relating information obtained at S 43 , whether the outside diameter of the wrapped member  302  is less than a preset standard diameter. For example, this standard diameter is greater than or equal to the first predetermined diameter and less than or equal to the second predetermined diameter (e.g., 4.1-7.1 mm). In the present modification, for example, this standard diameter is a first standard diameter (as one example of a first outside diameter) of 4.1 mm. When the outside diameter of the wrapped member  302  is less than the first standard diameter (S 130 : YES), this flow goes to S 150 . When the outside diameter of the wrapped member  302  is greater than or equal to the first standard diameter (S 130 : NO), this flow goes to S 135 . 
     The print-position setter  414  of the control circuit  2  at S 135  determines, based on the outside-diameter relating information obtained at S 43 , whether the outside diameter of the wrapped member  302  is greater than a second standard diameter (as one example of a second outside diameter) that is greater than the first standard diameter. For example, the second standard diameter is 7.1 mm. When the outside diameter of the wrapped member  302  is greater than the second standard diameter (S 135 : YES), this flow goes to S 145 . When the outside diameter of the wrapped member  302  is less than or equal to the second standard diameter (S 135 : NO), this flow goes to S 140 . 
     The print-position setter  414  of the control circuit  2  at S 140  sets the print positional alignment to the center alignment. Upon completion of this processing, this procedure ends, and the flow returns to S 5  in  FIG. 13 . 
     The print-position setter  414  of the control circuit  2  at S 145  sets the print positional alignment to the top alignment. Upon completion of this processing, this procedure ends, and the flow returns to S 5  in  FIG. 13 . 
     The print-position setter  414  of the control circuit  2  at S 150  sets the print positional alignment to the bottom alignment. Upon completion of this processing, this procedure ends, and the flow returns to S 5  in  FIG. 13 . 
     As a result of this procedure, the CPU executes the control based on the outside diameter of the wrapped member  302  such that when the outside diameter of the wrapped member  302  is less than the first standard diameter (e.g., 4.1 mm), the print positional alignment is set to the alignment toward the one side in the first direction and such that when the outside diameter of the wrapped member  302  is greater than the second standard diameter (e.g., 7.1 mm), the print positional alignment is set to the alignment toward the other side in the first direction. 
     In the present modification as described above, in the case where the outside diameter of the wrapped member  302  is small, for example, the entire character strings R are displaced in the character-string printable region RA toward one side (the lower side in  FIG. 42 ) in the first direction to prevent the character strings R from being covered with the printing background layer  25  as illustrated in  FIG. 39 , thereby reducing an amount of lowering of the viewability. On the other hand, in the case where the outside diameter of the wrapped member  302  is large, for example, the entire character strings R are displaced in the character-string printable region RA toward the other side (the upper side in  FIG. 28 ) in the first direction to cover the character strings R printed on the printing background layer  25  with the transparent base layer  21  unlike the case in  FIG. 40 , thereby ensuring the viewability and preventing the character strings R from being soiled or faded. In the present modification as described above, as in the second embodiment, it is possible to fill user&#39;s need for the character strings R to improve a convenience to the user. 
     Third Embodiment 
     There will be next explained a third embodiment. It is noted that the same reference numerals as used in the first embodiment and the modifications thereof are used to designate the corresponding elements of the third embodiment, and an explanation of which is simplified or dispensed with. 
     Rotatable Label Wrapping Manner and Self-Laminating Wrapping Manner 
     For example, it is usually considered that a wrapping manner in which the print label L is wrapped around the wrapped member  302  as described above includes: a rotatable label wrapping manner in which the print label L is wrapped around the wrapped member  302  so as to be rotatable as described above; and a self-laminating wrapping manner in which the print label L is wrapped around the wrapped member  302  so as not to be rotatable. 
     In the case where the print label L is used in the rotatable label wrapping manner, as described in, e.g., the first and second embodiments, a back surface of the portion of the base layer  21  in the adhesive region D 1  and a back surface of the portion of the base layer  21  in the partly-adhesive region D 3  are stuck to each other in a state in which the print label L is wrapped around the outer circumferential surface of the wrapped member  302 , and then portions of the print label L in the non-adhesive region D 2   a  and the partly-adhesive region D 3  are wrapped around the wrapped member  302  (see  FIGS. 8 and 23 , for example). In this case, since the portion of the print label L in the adhesive region D 1  is not stuck to the wrapped member  302 , and the portion of the print label L in the non-adhesive region D 2   a  is not adhesiveness, the print label L is rotatable around the wrapped member  302 . 
       FIGS. 48A and 48B  illustrate one example of the print label L used in the self-laminating wrapping manner.  FIGS. 48A and 48B  generally correspond to  FIGS. 3A and 3B , respectively. As illustrated in  FIGS. 48A and 48B , the marks M 1 , M 2  are not printed on the print label L unlike the structure illustrated in  FIGS. 3A and 3B . When the print label L is attached to the wrapped member  302 , as illustrated in  FIG. 49 , the back surface (the right surface in  FIG. 49 ) of the portion of the base layer  21  in the adhesive region D 1  is stuck to the wrapped member  302  via the adhesive layer  22 , and then the portions of the print label L in the non-adhesive region D 2   a  and the partly-adhesive region D 3  are wrapped around the wrapped member  302  in order as indicated by arrow H. In this case, since the portion of the base layer  21  in the adhesive region D 1  adheres to the wrapped member  302  via the adhesive layer  22 , the print label L is not rotatable around the wrapped member  302 . 
     As described above, the same print tape To may be used for the above-described two wrapping manners (the print tape To illustrated in  FIG. 2A  may be used for the above-described two wrapping manners in the above-described example), and only a use is different between the above-described two wrapping manners, for example. In the label creating apparatus  1 , however, a manner of creation of the print label L (which is performed by the thermal head  7  and the conveying roller  6 ) is in some cases preferably changed depending upon which wrapping manner is used between the above-described two wrapping manners. 
     That is, for example, in the case of the self-laminating wrapping manner, as described above with reference to  FIG. 49 , the portions of the print label L in the non-adhesive region D 2   a  and the partly-adhesive region D 3  are wrapped around the wrapped member  302  in the state in which the portion of the base layer  21  in the adhesive region D 1  is stuck to the wrapped member  302 , making it difficult to cause misalignment in wrapping. 
     In the case of the rotatable label wrapping manner, in contrast, as described above with reference to, e.g.,  FIG. 4 , when the back surface (the right surface in  FIG. 4A ) of the portion of the base layer  21  in the adhesive region D 1  and the back surface (the left surface in  FIG. 4A ) of the portion of the base layer  21  in the partly-adhesive region D 3  are stuck to each other in the state in which the portion of the print label L is wrapped around the wrapped member  302 , misalignment in sticking easily occurs, which may lead to misalignment in wrapping. 
     To solve this problem, in the case of the rotatable label wrapping manner, the CPU preferably executes control for forming the marks M 1 , M 2  on the portions of the print label L in the adhesive region D 1  and the partly-adhesive region D 3  such that each of the marks M 1  and a corresponding one of the marks M 2  are arranged in a line in the first direction as in the first embodiment. The marks M 1 , M 2  may be formed by the printer. In the case where the marks M 1  or M 2  are formed on the print tape To in advance, the CPU executes control for additionally print the other marks such that each of the marks M 1  and a corresponding one of the marks M 2  are arranged in a line in the up and down direction. This control creates the print label L with the two marks M 1 , M 2  arranged in the first direction. Thus, by aligning the two marks with each other in sticking in the rotatable label wrapping manner, it is possible to prevent misalignment in sticking and the misalignment in wrapping (see  FIGS. 4B and 4C  in the first embodiment, for example). In the case of the self-laminating wrapping manner, on the other hand, since the misalignment in wrapping does not easily occur, there is little need to provide the marks as described above. 
     The user may want to reliably cover the character strings R formed in the non-adhesive region D 2   a  with the base layer  21  as described above with reference to, e.g.,  FIGS. 25 and 29  in the second embodiment. In this case, in the case of the rotatable label wrapping manner, the length of wrapping is shorter than in the case of the self-laminating wrapping manner, leading to a possibility that all the character strings R cannot be covered with the base layer  21 . That is, in the case of the rotatable label wrapping manner, the CPU preferably executes control such that the portion of the non-adhesive region D 2   a  on which printing of the character strings R is allowed (the character-string printable region RA) is different from that in the case of the self-laminating wrapping manner. 
     In this third embodiment, the CPU changes control for the conveying roller  6  and the thermal head  7 , depending upon whether the print label L is wrapped in the rotatable label wrapping manner or the self-laminating wrapping manner. 
     Control Circuit 
     There will be next explained a configuration and a control procedure of the control circuit  2  for achieving the above-described functions in the present embodiment.  FIG. 50  illustrates a functional configuration of the control circuit  2 . In the present embodiment, as illustrated in  FIG. 50 , the control circuit  2  includes a wrapping-manner-information obtainer  403  in addition to the controller  500 , the information obtainer  400 , the correction-information obtainer  405 , the length obtainer  406 , and the selection receiver  407  provided in the first embodiment and the second embodiment. 
     The controller  500  includes a second region controller  402 , a mark controller  412 , and a disabling controller  413  in addition to the margin determiner  404 , the circumferential-direction mark-position setter  408 , the axial-direction mark-position setter  409 , the number-of-marks calculator  410 , and the region setter  401  provided in the first embodiment and the second embodiment. 
     The wrapping-manner-information obtainer  403  obtains wrapping-manner information indicating whether the print label L is to be wrapped in the rotatable label wrapping manner or the self-laminating wrapping manner. The wrapping manner indicated by the wrapping-manner information is input by the user via the operation device  3 . That is, in the present embodiment, the user is allowed to select whether the print label L is to be wrapped in the rotatable label wrapping manner or the self-laminating wrapping manner. 
     The controller  500  changes control for the conveying roller  6  and the thermal head  7 , depending upon whether the wrapping-manner information obtained by the wrapping-manner-information obtainer  403  indicates the rotatable label wrapping manner or the self-laminating wrapping manner. There will be explained this processing below specifically. 
     That is, the region setter  401  functions in the same manner as in the second embodiment based on the wrapping-manner information obtained by the wrapping-manner-information obtainer  403 . In the case of the rotatable label wrapping manner, the region setter  401  sets an occupying region of the character-string printable region RA in which printing of the character strings R by the thermal head  7  is allowed, based on the outside-diameter relating information on the wrapped member  302  which is obtained by the information obtainer  400 . That is, the region setter  401  sets a position, in the first direction, of the occupying region that is a region of the non-adhesive region D 2   b  which is occupied by the character-string printable region RA, to a different position between the case where the obtained wrapping-manner information indicates the rotatable label wrapping manner and the case where the wrapping-manner information indicates the self-laminating wrapping manner. Specifically, in the case where the wrapping-manner information indicates the rotatable label wrapping manner, as explained with reference to  FIG. 34 , in the case of the alignment different from the center alignment, the position and the height (including the maximum number of lines and the maximum character size of the character strings R in the character-string printable region RA) of the one-side end of the character-string printable region RA in the first direction are set adjustably to change the position of the occupying region when compared with the case of the self-laminating wrapping manner without such setting, and in the case of the center alignment, the maximum number of lines, the maximum character size and so on of the character strings R in the character-string printable region RA are set adjustably to change the position of the occupying region when compared with the case of the self-laminating wrapping manner without such setting. 
     In the case where the wrapping-manner information obtained by the wrapping-manner-information obtainer  403  indicates the rotatable label wrapping manner, the second region controller  402  functions the margin determiner  404  in the same manner as in the second embodiment to reduce the length, in the second direction, of an occupying region that is a region of the printing background layer  25  which is occupied by the character-string printable region RA when compared with the case where the wrapping-manner information indicates the self-laminating wrapping manner. Specifically, in the case where the obtained wrapping-manner information indicates the rotatable label wrapping manner, as explained with reference to  FIG. 15 , in the case where the outside diameter of the wrapped member  302  is less than or equal to the predetermined value assumed in advance, the second region controller  402  increases the length of each of the margin regions RS when compared with the case where the outside diameter of the wrapped member  302  is greater than the predetermined value, to reduce the occupying region of the character-string printable region RA when compared with the case of the self-laminating wrapping manner without such setting. 
     In the case of the rotatable label wrapping manner, the mark controller  412  functions the circumferential-direction mark-position setter  408  and the axial-direction mark-position setter  409  in the same manner as in the first embodiment. That is, the mark controller  412  controls the thermal head  7  and the conveying roller  6  to perform at least one of printing of the first marks M 1  on the adhesive region D 1  or the non-adhesive region D 2   a  and printing of the second marks M 2  on the partly-adhesive region D 3  such that each of the marks M 1  and a corresponding one of the marks M 2  are arranged in a line in the first direction. The disabling controller  413  executes control based on the wrapping-manner information obtained by the wrapping-manner-information obtainer  403 . That is, in the case where the obtained wrapping-manner information indicates the self-laminating wrapping manner, the disabling controller  413  disables the function of the mark controller  412 . In the case where the obtained wrapping-manner information indicates the rotatable label wrapping manner, the disabling controller  413  does not disable the function of the mark controller  412 . 
     Print Setting Processing 
       FIG. 51  illustrates the print setting processing executed by the CPU of the control circuit in the present embodiment to achieve the above-described technique.  FIG. 51  corresponds to  FIG. 14 . As illustrated in  FIG. 51 , in the present embodiment, the wrapping-manner-information obtainer  403  of the control circuit  2  at S 41  obtains the wrapping-manner information indicating whether the print label L is to be wrapped in the rotatable label wrapping manner or the self-laminating wrapping manner. 
     The disabling controller  413  of the control circuit  2  at S 42  determines whether the wrapping-manner information obtained at S 41  indicates the rotatable label wrapping manner. When the wrapping-manner information obtained at S 41  does not indicate the rotatable label wrapping manner (S 42 : NO), this procedure ends, and the flow returns to S 5  in  FIG. 13  without execution of processings at S 43 , S 44 , S 45 , and S 46 . In this case, in particular, skipping the processing at S 46  corresponds to disabling of the function by the mark controller  412 . When the wrapping-manner information obtained at S 41  indicates the rotatable label wrapping manner (S 42 : YES), this flow goes to S 43  similar to that in  FIGS. 14 and 33 . 
     As in the first and second embodiments, the information obtainer  400  of the control circuit  2  at S 43  obtains the outside-diameter relating information on the wrapped member  302  (the outside diameter of the wrapped member  302  or the module number, the type, or the like corresponding to the outside diameter) which is manually input via the operation device  3 , for example. 
     At S 44  similar to that in  FIG. 33 , the region setter  401  of the control circuit  2 , as in the second embodiment, executes the character-string-printable-region setting processing (see  FIG. 34 ) for adjustably setting the character-string printable region RA based on the outside-diameter relating information obtained at S 43 . 
     At S 45  similar to that in  FIG. 14 , the second region controller  402  and the margin determiner  404  of the control circuit  2 , as in the first embodiment, executes the right-and-left-margin setting processing to determine the length of each of the margin regions RS in the second direction, based on the outside-diameter relating information obtained at S 43  (see  FIG. 15 ). 
     At S 46  similar to that in  FIG. 14 , the mark controller  412 , the circumferential-direction mark-position setter  408 , the axial-direction mark-position setter  409 , and the number-of-marks calculator  410  of the control circuit  2  execute the mark setting processing for the marks M 1 , M 2  (see  FIG. 17 ) as in the first embodiment. Upon completion of this processing, this procedure ends, and the flow returns to S 5  in  FIG. 13 . 
     Effects in Third Embodiment 
     In the present embodiment as described above, control of the controller  500  of the control circuit  2  for controlling the conveying roller  6  and the thermal head  7  is changed depending upon whether the wrapping-manner information indicates the rotatable label wrapping manner or the self-laminating wrapping manner. This change enables the controller to execute control appropriate for each wrapping manner, resulting in improved convenience to the user. 
     In the present embodiment, in particular, the occupying region of the character-string printable region RA is different between the case of the rotatable label wrapping manner and the case of the self-laminating wrapping manner. This processing makes it possible to reliably cover the character strings R on the portion of the print label L in the non-adhesive region D 2   b  with the portion of the print label L in the partly-adhesive region D 3  as described above, for example. 
     In the present embodiment, in particular, only in the case of the rotatable label wrapping manner, control of the circumferential-direction mark-position setter  408  and the axial-direction mark-position setter  409  by the mark controller  412  is effectively executed, thereby creating the print label L with the first marks M 1  and the second marks M 2  arranged such that each of the marks M 1  and a corresponding one of the marks M 2  are arranged in a line in the first direction (see  FIG. 3 , for example). As a result, it is possible to prevent misalignment and skew of the print label L as described above. 
     In the present embodiment, in particular, in the case where the wrapping-manner information indicates the rotatable label wrapping manner, the second region controller  402  reduces the length, in the second direction, of the occupying region that is a region of the printing background layer  25  which is occupied by the character-string printable region RA, when compared with the case where the wrapping-manner information indicates the self-laminating wrapping manner. This reduction prevents the character strings R formed in the character-string printable region RA from being hidden by the marks M 1 , M 2  in the above-described wrapping, resulting in reduction in amount of lowering of the viewability. 
     In the above-described explanation, one example of the stickability is adhesion (adhesiveness) of the adhesive of the adhesive layer  22 , but the present disclosure is not limited to this configuration. For example, the present disclosure may use various structures including: a pressure pseudo-adhesive structure which is used for, e.g., postcards and in which a pseudo-adhesive portion of the label cannot be stuck once peeled; and a structure in which portions of the label are stuck to each other by static electricity like a resin sheet used for, e.g., wrapping. For example, the pseudo-adhesive material may have such a property that the material is wet before sticking, and once dried and peeled, the material cannot be stuck again. 
     It is noted that the first mark M 1  and the second mark M 2  may have different shapes.  FIG. 52  illustrates examples of shapes after sticking of the first mark M 1  and the second mark M 2  having different shapes. In the case where the first mark M 1  is a white circle with a black border, and the second mark M 2  is a solid black circle smaller than the first mark M 1 , when the two marks M 1 , M 2  overlap each other by the above-described sticking, the small black circle can be viewed within the white circle, making it easy for the user to recognize the overlapping state. 
     In the case where the first mark M 1  is a solid black circle, and the second mark M 2  is a solid black circle smaller than the first mark M 1 , when the two marks M 1 , M 2  overlap each other by the above-described sticking, the small solid black circle is hidden by the large solid black circle, making it easy for the user to recognize the overlapping state (that is, overlapping is proper if the second mark M 2  is not located off the first mark M 1 ). 
     In the case where the first mark M 1  is a cross, and the second mark M 2  is a cross formed by rotating the first mark M 1  by 45 degrees, when the two marks M 1 , M 2  overlap each other by the above-described sticking, the two crosses form an asterisk with a lateral line, making it easy for the user to recognize the overlapping state. 
     In the case where the first mark M 1  is a solid black square, and the second mark M 2  is a solid black square smaller than the first mark M 1 , when the two marks M 1 , M 2  overlap each other by the above-described sticking, the small solid black square is hidden by the large solid black square, making it easy for the user to recognize the overlapping state (that is, overlapping is proper if the second mark M 2  is not located off the first mark M 1 ). 
     While the terms “the same”, “equal”, “different”, and the like are used for dimensions and sizes in external appearance in the above-described explanation, these terms are not strictly used. That is, tolerance and error in design and manufacture are allowed, and “same”, “equal”, and “different” may be respectively interpreted as “substantially the same”, “substantially equal”, and “substantially different”.
