Title: Lengthy article take-up apparatus and lengthy article printer

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     The present application claims priority from Japanese Patent Application No. 2013-17212, which was filed on Jan. 31, 2013, the disclosure of which is incorporated herein by reference in its entirety. 
     BACKGROUND 
     Field 
     The present disclosure relates to a lengthy article take-up apparatus and lengthy article printer. 
     Description of the Related Art 
     The prior art discloses a label remover which feeds out a tape on which a large number of labels having an adhesive adhering to a back surface provisionally bonded serially from a roll and which sequentially removes labels one by one from the tape. In a cassette detachably attached to a recess portion of the label remover, a driven side engaging piece of a clutch is provided on one end surface of a take-up shaft winding a start end of the tape fed out of the roll. Moreover, in the label remover, a driving-side engaging piece of the clutch that can be engaged with the driven-side engaging piece of the take-up shaft is provided on one end of a driving shaft driving the take-up shaft. 
     Attachment of the cassette to the recess portion of this label remover is performed as follows. First, by sliding a slide button by fingers against a spring, a flange provided on the other end of the driving shaft is displaced by its displacing operation, and the driving-side engaging piece of the clutch provided on one end of the driving shaft is pulled into the recess portion. Subsequently, in the pulled-in state, the cassette is arranged into the recess portion. Subsequently, by removing the fingers from the slide button, the driving-side engaging piece of the clutch is engaged with the driven-side engaging piece by extension of the spring, and transmission of power to the take-up shaft in the cassette is enabled. 
     In the above described prior-art, since it is necessary to slide the slide button against a reaction force by the spring every time the cassette is attached/detached, there is a problem that operability is low. Moreover, a mechanism for advancing/retracting the driving-side engaging piece of the clutch including the spring, the slide button, the flange and the like is necessary, and the structure becomes complicated. 
     SUMMARY 
     The present disclosure comprises an object to provide a lengthy article take-up apparatus and lengthy article printer which can improve operability and can simplify the structure while power is reliably transmitted to the take-up shaft. 
     In order to achieve the above-described object, according to the aspect of the present application, there is provided a lengthy article take-up apparatus configured to wind a lengthy article, comprising a housing constituting an outer shell of the printer, a winding core member detachably attached to the housing and configured to take up the lengthy article, a bearing portion disposed on the housing, and a driving gear disposed on the housing, wherein the winding core member comprises a shaft member configured to be detachably fitted to the bearing portion, a cylindrical winding body disposed rotatably on an outer periphery of the shaft member and configured to wind the lengthy article on an outer peripheral side, a driven gear fixed to the winding body and configured to be meshed with the driving gear when the winding core member is attached to the housing, and a lock member configured to fix the shaft member to the bearing portion when the winding core member is attached to the housing. 
     In a lengthy article take-up apparatus of the present disclosure, a lengthy article is wound by a winding core member around a winding cylinder. The winding core member has a shaft member, a take-up shaft, a driven gear, and a lock member and is configured to be detachably attached to a housing. The driven gear is meshed with a driving gear disposed on the housing when being attached to the housing of the winding core member. At this time, by fixing the shaft member by the lock member to a bearing portion, the take-up shaft and the driven gear are positioned, and thus, tooth skip in a connection portion between the driving gear and the driven gear can be suppressed. As a result, power of the driving gear can be reliably transmitted to the take-up shaft. 
     Moreover, in the present disclosure, the lock member which can fix the shaft member to the bearing portion is disposed not on the housing but on the winding core member of the lengthy article take-up apparatus. If the lock member is configured to be disposed on the housing, such a lock mechanism can be considered that by pulling the bearing portion urged by a spring, for example, in a direction of protruding from the housing into the housing by a slide button or the like, by attaching the winding core member in the pulled-in state, and by separating the finger from the slide button after that, the bearing portion is engaged with a bearing member by extension of the spring. In the case of such configuration, every time the winding core member is attached/detached, the slide button needs to be slid against a reaction force by the spring, and operability is low. Particularly, if a force of the spring is made stronger in order to improve a lock function, a force required for a sliding operation increases with that, and the operability is lowered. Thus, the lock function and the operability cannot be both realized. Moreover, an advancing/retracting mechanism of the bearing portion including the spring, the slide button and the like is required, which makes the structure complicated. 
     In the present disclosure, the lock member is disposed on the winding core member. As a result, such a structure in which the shaft member is made to swing around the shaft core by an operation of the lock member, for example, and the shaft member is fixed to the bearing portion by engagement can be realized. Therefore, since the aforementioned operation against the reaction force of the spring or the like is no longer necessary, operability of the winding core member during attachment/detachment can be improved. That is, since the shaft member can be firmly fixed to the bearing portion with an easy operation, the lock function and operability can be both realized. Moreover, since a mechanism for advancing/retracting the bearing portion including the spring, the slide button and the like is no longer necessary, the structure can be simplified.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     An embodiment of the present disclosure will be described below by referring to the attached drawings. If “front”, “rear”, “left”, “right”, “upper”, and “lower” are noted in the drawings, the “front”, “rear”, “left”, “right”, “upper”, and “lower” in the description indicate the noted directions. 
     &lt;Outline Configuration of Adhesive Tape Printer&gt; 
     First, an outline configuration of an adhesive tape printer of the present embodiment will be described by referring to  FIGS. 1 to 6 . 
     In  FIGS. 1 to 6 , the adhesive tape printer  1  of the present embodiment has a housing  2  constituting an outer shell of the apparatus, a rear opening/closing portion  8 , and a front opening/closing cover  9 . 
     The housing  2  is provided with a housing body  2   a , a first accommodating portion  3  disposed on the rear side of the housing body  2   a , and a second accommodating portion  4  and a third accommodating portion  5  disposed on the front side of the housing body  2   a . The first accommodating portion  3 , the second accommodating portion  4 , and the third accommodating portion  5  will be described later in detail. 
     The rear opening/closing portion  8  is connected capable of opening/closing to an upper part on the rear side of the housing body  2   a . This rear opening/closing portion  8  can open/close an upper part of the first accommodating portion  3  by rotationally moving. This rear opening/closing portion  8  is constituted by a first opening/closing cover  8   a  and a second opening/closing cover  8   b.    
     The first opening/closing cover  8   a  can open/close the upper part on the front side in the first accommodating portion  3  by rotationally moving around a predetermined rotational movement axis K 1  disposed on the upper part on the rear side of the housing body  2   a . In more detail, the first opening/closing cover  8   a  can rotationally move from a closing position where the upper part on the front side in the first accommodating portion  3  is covered (state in  FIGS. 1 to 3 ) to an open position where the upper part on the front side in the first accommodating portion  3  is exposed (state in  FIGS. 4 and 5 ). At this time, the rotational movement axis K 1  of the first opening/closing cover  8   a  has its position in a longitudinal direction located on the rear side of a roll center RO of a first roll R 1  which will be described later, accommodated in the first accommodating portion  3  and has a position in a vertical direction located on an upper side of the roll center RO. 
     Inside the first opening/closing cover  8   a , a head holding body  10  is disposed (See  FIG. 4 ). The first opening/closing cover  8   a  can relatively bring/separate a print head  11  provided on the head holding body  10  and which will be described later to/from a feeding roller  12  disposed on the housing body  2   a  and which will be described later by rotationally moving around the above described rotational movement axis K 1 . In detail, the first opening/closing cover  8   a  can rotationally move from a closed position (state in  FIG. 2 ) where the print head  11  is close to the feeding roller  12  to an open position (state in  FIG. 6 ) where the print head  11  is away from the feeding roller  12 . 
     The second opening/closing cover  8   b  is disposed on the rear side of the above described first opening/closing cover  8   a  and can open/close the upper part on the rear side in the first accommodating portion  3  separately from opening/closing of the above described first opening/closing cover  8   a  by rotationally moving around a predetermined rotational movement axis K 2  disposed on an upper end portion on the rear side of the housing body  2   a . In detail, the second opening/closing cover  8   b  can rotationally move from a closed position (state in  FIGS. 1 and 2 ) covering the upper part on the rear side in the first accommodating portion  3  to an open position (state in  FIGS. 3 to 5 ) exposing the upper part on the rear side in the first accommodating portion  3 . At this time, the position of the rotational movement axis K 2  of the second opening/closing cover  8   b  in the longitudinal direction is further on the rear side of the rotational movement axis K 1  of the above described first opening/closing cover  8   a  and the position in the vertical direction is further on the upper side of the rotational movement axis K 1 . The position in the vertical direction of the rotational movement axis K 2  of the second opening/closing cover  8   b  may be the same as that of the rotational movement axis K 1  of the above described first opening/closing cover  8   a.    
     When the first opening/closing cover  8   a  and the second opening/closing cover  8   b  are in the closed state, respectively, an outer peripheral portion  18  of the first opening/closing cover  8   a  and an edge portion  19  of the second opening/closing cover  8   b  are configured to be brought into contact with each other and to cover substantially the whole upper part of the first accommodating portion  3 . 
     The front opening/closing cover  9  is connected to an upper part on the front side of the housing body  2   a , capable of being opened/closed. This front opening/closing cover  9  can open/close an upper part of the second accommodating portion  4  by rotationally moving around a predetermined movement axis K 3  disposed on an upper end portion on the front side of the housing body  2   a . In detail, the front opening/closing cover  9  can rotationally move from a closed position (state in  FIGS. 1 to 4 ) covering the upper part on the second accommodating portion  4  to an open position (state in  FIG. 5 ) exposing the upper part of the second accommodating portion  4 . 
     At this time, at a first predetermined position  13  below the front opening/closing cover  9  in the closed state in the housing body  2   a , an adhesive tape cartridge TK (tape cartridge) is detachably attached. The adhesive tape cartridge TK is provided with a first roll R 1 , a third roll R 3 , and a connecting arm  16  for connecting the first roll R 1  and the third roll R 3 . 
     The first roll R 1  is supported by the connecting arm  16  on a rear side of the adhesive tape cartridge TK and is rotatable when the adhesive tape cartridge TK is attached to the housing body  2   a . The first roll R 1  has a print-receiving adhesive tape  150  consumed by feeding-out wound around an axis O 1  in the left-and-right direction in advance. At this time, the first roll R 1  is received in the first accommodating portion  3  from above by attachment of the adhesive tape cartridge TK and accommodated in a state in which the axis O 1  of winding of the print-receiving adhesive tape  150  is oriented in the left-and-right direction. The first roll R 1  feeds out the print-receiving adhesive tape  150  by rotating in a predetermined rotating direction (an A direction in  FIG. 2 ) in the first accommodating portion  3  in the state accommodated in the first accommodating portion  3  (in the state in which the adhesive tape cartridge TK is attached). The print-receiving adhesive tape  150  has a base layer  153 , an adhesive layer  152 , and a separation material layer  151  laminated from one side (upper side in a partially enlarged view in  FIG. 2 ) to the other side (lower side in the partially enlarged view in  FIG. 2 ) in a thickness direction in this order. The base layer  153  is a layer on which a desired print is formed by the print head  11  which will be described later. The adhesive layer  152  is a layer for bonding the base layer  153  on an appropriate bonded body (not shown). The separation material layer  151  is a layer covering the adhesive layer  152 . 
     Moreover, the feeding roller  12  is disposed on the upper side between the first accommodating portion  3  and the third accommodating portion  5  in the housing body  2   a . The feeding roller  12  is driven by a feeding motor M 1  disposed on the housing body  2   a  through a gear mechanism (not shown) so as to feed the print-receiving adhesive tape  150  fed out of the first roll R 1  accommodated in the first accommodating portion  3  in a tape posture in which a tape width direction is the left-and-right direction. 
     Moreover, the print head  11  is provided on the head holding body  10  disposed on the first opening/closing cover  8   a . The print head  11  can relatively get close to/separate from the feeding roller  12  by rotational movement of the first opening/closing cover  8   a  around the rotational movement axis K 1  as described above. That is, if the first opening/closing cover  8   a  is in the closed state, the print head  11  gets close to the feeding roller  12 , while if the first opening/closing cover  8   a  is in the open state, the print head  11  separates from the feeding roller  12 . This print head  11  is arranged at a position faced with the upper part of the feeding roller  12  in the first opening/closing cover  8   a  in the closed state in the head holding body  10  so that the print-receiving adhesive tape  150  being fed by the feeding roller  12  is sandwiched in collaboration with the feeding roller  12 . Therefore, if the first opening/closing cover  8   a  is in the closed state, the print head  11  and the feeding roller  12  are arranged by facing each other in the vertical direction. The print head  11  forms the desired print on the base layer  153  of the print-receiving adhesive tape  150  sandwiched by the feeding roller  12  by using an ink ribbon IB of a ribbon cartridge RK which will be described later so as to form an adhesive tape  150 ′ with print. 
     Moreover, at this time, at a second predetermined position  14  below the first opening/closing cover  8   a  in the closed state in the housing body  2   a  and above the adhesive tape cartridge TK, the ribbon cartridge RK is detachably attached. The ribbon cartridge RK is provided with a ribbon supply roll R 4  and a ribbon take-up roll R 5 . 
     The ribbon supply roll R 4  is rotatably supported on a rear side of the ribbon cartridge RK and feeds out the ink ribbon IB for forming a print by the print head  11  by rotating in a predetermined rotating direction (a D direction in  FIG. 2 ) in a state in which the ribbon cartridge RK is attached. 
     The ribbon take-up roll R 5  is rotatably supported on a front side of the ribbon cartridge RK and takes up the used ink ribbon IB after the print is formed by rotating in a predetermined rotating direction (an E direction in  FIG. 2 ) in the state in which the ribbon cartridge RK is attached. 
     Moreover, on a downstream side of the print head  11  along a tape feeding direction in the first opening/closing cover  8   a , a ribbon take-up roller  15  is provided. The ribbon take-up roller  15  guides the used ink ribbon IB to the ribbon take-up roll R 5 . 
     That is, the ink ribbon IB fed out of the ribbon supply roll R 4  is arranged on the print head  11  side of the print-receiving adhesive tape  150  in the state sandwiched between the print head  11  and the feeding roller  12  and is brought into contact with a lower part of the print head  11 . Then, after the ink of the ink ribbon IB is transferred by heating from the print head  11  on the base layer  153  of the print-receiving adhesive tape  150  and the print is formed, the used ink ribbon IB is taken up by the ribbon take-up roll R 5  while being guided by the ribbon take-up roller  15 . 
     The connecting arm  16  is provided with a peeling-off portion  17  having a substantially horizontal slit shape, for example, on an upstream side of the third roll R 3  along the tape feeding direction. The peeling-off portion  17  is a portion to peel off the separation material layer  151  from the adhesive tape  150 ′ with print fed out of the first roll R 1  and fed to the front side. By peeling-off of the separation material layer  151  from the adhesive tape  150 ′ with print by the peeling-off portion  17 , the tape is separated into the separation material layer  151  and an adhesive tape  150 ″ with print formed of the base layer  153  and the adhesive layer  152  other than that. Then, the peeled-off separation material layer  151  is taken up and wound, whereby the above described third roll R 3  is formed. Moreover, the adhesive tape  150 ″ with print from which the separation material layer  151  has been peeled off is wound on the outer peripheral side of winding core member  40  which will be described later so that a second roll R 2  which will be described later is formed. 
     The third roll R 3  is supported by the connecting arm  16  on the front side of the adhesive tape cartridge TK (that is, on the downstream side of the first roll R 1  along the tape feeding direction). In the state in which the adhesive tape cartridge TK is attached to the housing body  2   a , the third roll R 3  is rotatable and winds the separation material layer  151  having been peeled off the adhesive tape  150 ′ with print around an axis O 3  in the left-and-right direction. At this time, the third roll R 3  is received in the third accommodating portion  5  from above by attachment of the adhesive tape cartridge TK and is accommodated in the state in which the winding axis O 3  of the separation material layer  151  is oriented in the left-and-right direction. Subsequently, the third roll R 3  is driven by a separation sheet take-up motor M 3  disposed on the housing body  2   a  through the gear mechanism (not shown) in a state accommodated in the third accommodating portion  5  (state in which the adhesive tape cartridge TK is attached) and takes up the separation material layer  151  by rotating in a predetermined rotating direction (a C direction in  FIG. 2 ) in the third accommodating portion  5 . A configuration of the connecting arm  16  other than the above and a support configuration of the first roll R 1  and the third roll R 3  will be described later in more detail. 
     Moreover, in the second accommodating portion  4 , a winding core member  40  around which the adhesive tape  150 ″ with print obtained by peeling off the separation material layer  151  from the adhesive tape  150 ′ with print is sequentially wound is received from above and accommodated so as to be rotatably supported around an axis O 2  in the state in which the winding axis O 2  of the adhesive tape  150 ″ with print is oriented in the left-and-right direction. Subsequently, the winding core member  40  is driven by the adhesive take-up motor M 2  disposed on the housing body  2   a  through the gear mechanism in the state accommodated in the second accommodating portion  4  and takes up and laminates the adhesive tape  150 ″ with print by rotating in a predetermined rotating direction (a B direction in  FIG. 2 ) in the second accommodating portion  4 . As a result, the adhesive tape  150 ″ with print is sequentially wound on the outer peripheral side of the winding core member  40 , and the second roll R 2  is formed. Moreover, on an inner surface of the front opening/closing cover  9 , a pressing roller  37  supported in a direction toward an outer peripheral surface of the second roll R 2  through a predetermined urging member is disposed. If an outer diameter of the second roll R 2  is sufficiently large, a tip end of the pressing roller  37  is urged to and brought into contact with the outer peripheral surface of the second roll R 2 . Configurations of the above described winding core member  40  and the periphery of the axis O 2  will be described later in more detail. 
     &lt;Outline of Operation of Adhesive Tape Printer&gt; 
     Subsequently, an outline of an operation of the adhesive tape printer  1  will be described. 
     That is, when the adhesive tape cartridge TK is attached at the first predetermined position  13 , the first roll R 1  is accommodated in the first accommodating portion  3  located on the rear side of the housing body  2   a , and the third roll R 3  is accommodated in the third accommodating portion  5  located on the front side of the housing body  2   a . Moreover, in the second accommodating portion  4  located on the front side of the housing body  2   a , the winding core member  40  for forming the second roll R 2  is accommodated. 
     At this time, if the feeding roller  12  is driven, the print-receiving adhesive tape  150  to be fed out by rotation of the first roll R 1  accommodated in the first accommodating portion  3  is fed to the front side. Then, a desired print is formed by the print head  11  on the base layer  153  of the print-receiving adhesive tape  150  being fed, and the adhesive tape  150 ′ with print is formed. The adhesive tape  150 ′ with print formed is further fed to the front side, and when it is fed to the peeling-off portion  17 , the separation material layer  151  is peeled off in the peeling-off portion  17 . The peeled-off separation material layer  151  is fed to a lower side and introduced into the third accommodating portion  5  and wound in the third accommodating portion  5 , and the third roll R 3  is formed. 
     On the other hand, the adhesive tape  150 ″ with print from which the separation material layer  151  has been peeled off is further fed to the front side and introduced into the second accommodating portion  4  and wound on the outer peripheral side of the winding core member  40  in the second accommodating portion  4 , and the second roll R 2  is formed. At that time, a cutter mechanism  30  disposed on the front opening/closing cover  9  on the rear side of the second roll R 2 , that is, on an upstream side of the second roll R 2  along the tape feeding direction cuts the adhesive tape  150 ″ with print on which the print is formed and from which the separation material layer  151  has been peeled off. As a result, the adhesive tape  150 ″ with print being wound around the second roll R 2  at timing desired by the user can be cut and the second roll R 2  can be taken out of the second accommodating portion  4  after the cutting. 
     &lt;Detailed Structure of Each Portion&gt; 
     Subsequently, a detailed structure of each portion of the adhesive tape printer  1  will be described in order. 
     &lt;Adhesive Tape Cartridge&gt; 
     In  FIGS. 6 and 7 , the adhesive tape cartridge TK is provided with, as described above, the first roll R 1 , the third roll R 3 , and the connecting arm  16 . The connecting arm  16  is provided with a pair of left and right first bracket portions  20  and  20  disposed on the rear side and a pair of left and right second bracket portions  21  and  21  disposed on the front side. In  FIG. 7 , the print-receiving adhesive tape  150  wound around the axis O 1  in the first roll R 1  and the separation material layer  151  wound around the axis O 3  in the third roll R 3  are not shown, and a part of members constituting the first roll R 1  and the third roll R 3  is not shown. 
     The first bracket portions  20  and  20  sandwich the first roll R 1  from both the left and night sides along the axis O 1  and holds the first roll R 1  rotatably around the axis O 1  in a state in which the adhesive tape cartridge TK is attached to the housing body  2   a . These first bracket portions  20  and  20  are connected by a first connection portion  22  extended substantially along a left-and-right direction on an upper end portion, avoiding interference with an outer diameter of the first roll R 1 . 
     The second bracket portions  21  and  21  sandwich the third roll R 3  from both the left and night sides along the axis O 3  and holds the third roll R 3  rotatably around the axis O 3  in a state in which the adhesive tape cartridge TK is attached to the housing body  2   a . These second bracket portions  21  and  21  are connected by a second connection portion  23  extended substantially along the left-and-right direction on the upper end portion. 
     The first bracket portions  20  and  20  and the first connection portion  22  on the rear side and the second bracket portions  21  and  21  and the second connection portion  23  on the front side are connected by a pair of left and right roll connecting beam portions  24  and  24 . 
     Here, as described above, when the adhesive tape cartridge TK is in use, by feeding the print-receiving adhesive tape  150  out of the first roll R 1  and feeding the same, the print-receiving adhesive tape  150  is consumed. On the other hand, the print receiving-adhesive tape  150  is fed to the third roll R 3 , and the separation material layer  151  peeled off by the above described peeling-off portion  17  from the adhesive tape  150 ′ with print on which the print is formed is wound around the axis O 3 . 
     As the result of the use form as above, if the tape roll freely rotates in the state of a single body of the adhesive tape cartridge TK before attachment to the housing, the tape might become disarrayed or loose. In this case, the disarray or loosening of the tape needs to be solved at attachment of the adhesive tape cartridge TK to the housing, and handling performance by the user deteriorates. 
     Thus, in the present embodiment, as illustrated in  FIGS. 8A to 10B , an outer diameter D 1  of a first shaft end portion R 1   a  disposed on both sides in an axial direction of the first roll R 1  is set to a dimension sufficiently smaller than an inner diameter D 2  of a first shaft hole portion R 1   b  for insertion at each of the first bracket portions  20  and  20 . That is, each of the first shaft end portions R 1   a  is loosely fitted in each of the first shaft hole portions R 1   b  with a sufficient gap. A plurality of outer peripheral projecting portions  61  are disposed at equal intervals on an outer peripheral surface of each of the first shaft end portions R 1   a  on the entire circumferential direction, and a plurality of inner peripheral projecting portions  62  are disposed at equal intervals on an inner peripheral surface of each of the first shaft hole portions R 1   b  on the entire circumferential direction. In this example, the outer peripheral projecting portions  61  and the inner peripheral projecting portions  62  are disposed in the same number and having the same projecting height and shape. 
     For example, if the adhesive tape cartridge TK is attached to the housing body  2   a , as illustrated in  FIGS. 8A and 8B , the first shaft end portions R 1   a  and the first shaft hole portions R 1   b  are coaxially arranged. In this state, the outer peripheral surfaces of the first shaft end portions R 1   a  and the inner peripheral surfaces of the first shaft hole portions R 1   b  are separated with the same gap between them over the entire circumferential direction, and the above described inner peripheral projecting portion  62  and the outer peripheral projecting portion  61  are set to have the respective projecting height dimensions so that they do not engage (interfere) with each other in this gap. That is, the inner peripheral surface of the first shaft hole portion R 1   b  and the outer peripheral surface of the first shaft end portion R 1   a  are configured so as to be faced with each other in the radial direction through a predetermined interval so that the inner peripheral projecting portion  62  and the outer peripheral projecting portion  61  do not engage with each other. Thus, if the adhesive tape cartridge TK is attached to the housing body  2   a , the first end portion R 1   a  is rotatable in the first shaft hole portion R 1   b.    
     Moreover, since the connecting arm  16  has the structure for holding the first roll R 1  in a suspended state, in the state in which the adhesive tape cartridge TK is removed from the housing body  2   a  and lifted up as illustrated in  FIGS. 9A and 9B , the first roll R 1  relatively moves downward by gravity, and the first shaft end portion R 1   a  is brought into contact with the lower side of the first shaft hole portion R 1   b . As a result, the inner peripheral projecting portion  62  is engaged with the outer peripheral projecting portion  61 , and the first roll R 1  is made unrotatable. 
     Moreover, in a state in which the adhesive tape cartridge TK is placed on a table or the like as illustrated in  FIGS. 10A and 10B , the first roll R 1  relatively moves upward and the first shaft end portion R 1   a  is brought into contact with the upper side of the first shaft hole portion R 1   b . As a result, in this case, too, the inner peripheral projecting portion  62  is engaged with the outer peripheral projecting portion  61 , and the first roll R 1  is made unrotatable. 
     As described above, in the state of the adhesive tape cartridge TK alone before being attached to the housing body  2   a , the inner peripheral projecting portion  62  is engaged with the outer peripheral projecting portion  61  so as to bring the first roll R 1  into an unrotatable state, while in the state in which the adhesive tape cartridge TK is attached to the housing body  2   a , the inner peripheral projecting portion  62  is not engaged with the outer peripheral projecting portion  61 , and the first roll R 1  can be brought into a rotatable state. As a result, disarray or loosening of the tape in the state of the adhesive tape cartridge TK alone can be suppressed. 
     Moreover, in the present embodiment, a second shaft end portion R 3   a  disposed on both sides in the axial direction of the third roll R 3  and a second shaft hole portion R 3   b  for insertion in each of the second bracket portions  21  and  21  also have the similar supporting configuration (the outer peripheral projecting portion  61  and the inner peripheral projecting portion  62 ). Enlarged views in  FIGS. 8B, 9B, and 10B  illustrate a support state of the first shaft hole portion R 1   b  and the first shaft end portion R 1   a  and the support state of the second shaft hole portion R 1   b  and the second shaft end portion R 1   a  in corresponding  FIGS. 8A, 9A, and 10A , respectively. 
     &lt;Detailed Structure of Cutter Mechanism&gt; 
     As illustrated in  FIGS. 11, 12, and 13 , the cutter mechanism  30  has a guide plate  31 , a movable blade  32 , a running body  33  provided with a movable blade support portion  33   a  supporting the movable blade  32 , and a guide rail  34 . 
     The guide plate  31  is extended in the tape width direction on the downstream side in the tape feeding direction from the feeding roller  12  inside an open edge side of the second opening/closing cover  4 . This guide plate  31  is supported by a pair of left and right support plates  35   a  and  35   b  with respect to the second opening/closing cover  4 . The guide plate  31  is brought into contact with and guides upper surfaces of the adhesive tapes  152  and  153  (in other words, the upper surface of the base layer  153 ) with print fed by the feeding roller  12  in the above described housing  2  in a posture in which the tape width direction is the left-and-right direction (see virtual lines in  FIGS. 12 and 13 ). 
     Below the guide plate  31 , the above described movable blade  32  is arranged so as to have an edge  32   a  faced with the guide plate  31  in the vertical direction (so that the edge  32   a  is oriented upward in this example). The movable blade  32  runs in the tape width direction along the guide plate  31  by the above described running body  33  guided by the guide rail  34  and made to run by driving of a cutter motor M 4  and performs cutting (see an arrow C in  FIG. 12 ). The above described guide rail  34  is supported by the above described pair of left and right support plates  35   a  and  35   b  with respect to the second opening/closing cover  4 . 
     The movable blade  32  advances from the adhesive layer  152  on the lowest layer to the adhesive tapes  152  and  153  with print and performs the cutting while sandwiching the adhesive tapes  152  and  153  with print between the guide plate  31  and itself by the running of the running body  33  along the guide rail  34 . At that time, the above described movable blade support portion  33   a  supports the movable blade  32  with respect to the running body  33  so that the edge  32   a  of the movable blade  32  (see  FIG. 12 ) is inclined in a form pressing the adhesive tapes  152  and  153  with print to a direction of the guide plate  31  to the running direction along the tape width (in descending inclination in this example). As a result, the adhesive tapes  152  and  153  with print are cut by the edge  32   a  of the movable blade  32  arranged below and oriented diagonally upward in the width direction and advancing from the adhesive layer  152  on the lowest layer and cutting into while the upper surface (in more detail, the upper surface of the base layer  153  after the print is formed by the print head  11 ) is brought into contact with and guided by the guide plate  31 . At this time, a slit  31   a  is drilled in the tape width direction in the guide plate  31  in order to guide running of the movable blade  32  by the running body  33 . 
     On the downstream side of the guide plate  31  along the tape feeding direction, a chute  15  for switching feeding paths of the adhesive tapes  152  and  153  with print between a side toward the second roll R 2  and a side toward a discharging exit  12 . 
     &lt;Detailed Configuration Around Winding Core Member and Axis O 2 &gt; 
     Moreover, in the present embodiment, a single body of the winding core member  40  is attached to the second accommodating portion  4  as described above, and the adhesive tape  150 ″ with print is taken up on the outer peripheral side of this winding core member  40  and laminated so that the second roll R 2  is formed. In  FIGS. 14 to 16 , two bearing portions  39  which are projections each having a substantially columnar shape are fixedly disposed on the both left and right sides along the axis O 2  direction by facing each other when the second roll R 2  is attached so as to respectively sandwich the second roll R 2  in the second accommodating portion  4  of the housing body  2   a . The winding core member  40  is supported so that a center part of the winding core member  40  is rotatable by attaching each of the shaft end portions on the both sides in the axial direction thereof to the bearing portions  39 , respectively. Moreover, below on the rear side of the left bearing portion  39  in the second accommodating portion  4  of the housing body  2   a , a part of a tooth surface of a driving gear  38  interlocking with the above described adhesive take-up motor M 2  is exposed toward the bearing portion  39 . In  FIGS. 14 and 15 , the second roll R 2  is not shown, and in  FIGS. 18A and 18B , the adhesive tape  150 ″ with print and the front opening/closing cover  9  are not shown. 
     In  FIG. 16 , the winding core member  40  is configured such that the shaft end portions on the both sides in the axial direction are connected and become a support shaft with a small diameter as will be described later in detail, and this penetrates a shaft center of a drum portion  50  at the center around which the adhesive tape  150 ″ with print is wound and supports it rotatably (see  FIG. 17  which will be described later). On an outer periphery on the right side of the drum portion  50 , a first outer tube  42  provided with a flange having a substantially annular shape is attached, while on the outer periphery on the left side of the drum portion  50 , a second outer tube  43  provided with a flange having the substantially annular shape is attached. This second outer tube  43  is attached movably in the axial direction (left-and-right direction) within a predetermined range on a left end side of the winding core member  40 . As a result, the adhesive tape  150 ″ with print wound around the winding core member  40  can be sandwiched by the first outer tube  42  and the second outer tube  43  in accordance with the tape width in the width direction appropriately. 
     At a predetermined circumferential position on the left end side of the winding core member  40 , a portion-to-be-detected  81  whose exposed width changes in accordance with a moved position of the above described second outer tube  43  is disposed. This portion-to-be-detected  81  is formed having a shape so that an exposed amount of an irregular wave changes in accordance with the exposed width (see a broken line portion in the figure). When the winding core member  40  is to be attached to the second accommodating portion  4  of the housing body  2   a , it is attached so that this portion-to-be-detected  81  is located below. On the second accommodating portion  4  of the housing body  2   a , a detection portion  82  is disposed at a position faced with the portion-to-be-detected  81  when the winding core member  40  is attached. Though not shown in detail, this detection portion  82  detects the exposed amount of the irregular wave of the portion-to-be-detected  81  faced with itself mechanically or optically and discriminates a position of the above described second outer tube  43  in the axial direction. As a result, the tape width of the adhesive tape  150 ″ with print sandwiched by the first outer tube  42  and the second outer tube  43  can be automatically detected on the adhesive tape printer  1  side, and moreover, a type and a base diameter of the second roll R 2  can be also discriminated on the basis of this tape width. 
     Moreover, on a position in the vicinity of a lower part of the left bearing portion  39  (a rear surface position of the bearing portion  39  when seen in  FIG. 16 ), a projecting portion  36  having a substantially square cylinder shape is disposed (which will be described later in detail). 
     In  FIGS. 17 and 18 , the winding core member  40  is provided with a substantially cylindrical inner tube  41  (winding tube), the first outer tube  42 , the second outer tube  43 , a shaft member  51 , a driven gear  52 , and a lock member  53  sharing the above described axis O 2  as their axes. 
     The first outer tube  42  is detachably attached to the outer peripheral side of one side end portion (a right end portion in detail) along the axial direction of the inner tube  41  (that is, left-and-right direction which is the axis O 2  direction). This first outer tube  42  is provided with a substantially cylindrical first cylinder portion  45  and a substantially annular-shaped first flange portion  46  formed integrally on a right end portion of the first cylinder portion  45 . 
     The second outer tube  43  is attached to the outer peripheral side of the other side end portion (a left end portion in detail) along the axial direction of the inner tube  41  (that is, left-and-right direction which is the axis O 3  direction). This second outer tube  43  is provided with a substantially cylindrical second cylinder portion  47  and a substantially annular-shaped first flange portion  48  formed integrally on a left end portion of the second cylinder portion  47 . This second outer tube  43  is, as described above, attached movably in the axial direction (left-and-right direction) within a predetermined range on the left end side of the winding core member  40 . The inner tube  41 , the first outer tube  42 , and the second outer tube  43  constitute the above described drum portion  50 . 
     In a state in which the first outer tube  42  and the second outer tube  43  are attached to the inner tube  41 , the first flange portion  46  and the second flange portion  48  are arranged by facing each other in the axial direction, and a space that can receive the above described adhesive tape  150 ″ with print is formed between the first flange portion  46  and the second flange portion  48 . 
     Moreover, in a state in which the first outer tube  42  and the second outer tube  43  are attached to the inner tube  41 , the first cylinder portion  45  and the second cylinder portion  47  are extended substantially along the axis O 2  so as to connect the first flange portion  46  and the second flange portion  48 , and to the outer peripheral sides of the first cylinder portion  45  and the second cylinder portion  47  (in other words, the space between the first flange portion  46  and the second flange portion  48 ), a substantially cylindrical paper core  44  can be attached. The paper core  44  is a supply member for being wound with the adhesive tape  150 ″ with print obtained by peeling off the separation material layer  151  from the adhesive tape  150 ′ with print in the aforementioned peeling-off portion  17  on an outer peripheral side so that the tape width direction is the left-and-right direction.  FIG. 18  illustrates a state in which the paper core  44  is not attached to the outer peripheral sides of the first cylinder portion  45  and the second cylinder portion  47  (the same applies to  FIG. 16 ). 
     The shaft member  51  is a member having substantially columnar shape in general and is provided with a first engagement portion  51   a  capable of being attached to the above described bearing portion  39  installed on the housing body  2   a  on an end portion on the right side, a shank portion  51   b  having a diameter smaller than that of the first engagement portion  51   a  at a center part in the axial direction, and a shaft connection portion  51   c  on an end portion on the left side. A through hole  41   a  is disposed at a shaft center of the inner tube  41 , and by penetration of the shank portion  51   b  of the shaft member  51  through this through hole  41   a , the inner tube  41  is rotatably supported by the shaft member  51 . 
     The driven gear  52  is a gear capable of being meshed with the driving gear  38  disposed on the second accommodating portion  4  of the housing body  2   a , and an insertion tube  52   a  provided with a key on an outer peripheral surface is disposed at a center on an end face on the right side. By inserting this insertion tube  52   a  through a left end opening portion of the through hole  41   a  of the inner tube  41 , the driven gear  52  and the inner tube  41  (and the first outer tube  42  and the second outer tube  43 ) can integrally rotate. A through hole  52   b  is formed also at an shaft center of the entire driven gear  52  including the insertion tube  52   a , and a left end portion of the above described shaft member  51  can penetrate the inner tube  41  and the driven gear  52  which are connected. 
     The lock member  53  is provided with a substantially cup-shaped cover portion  53   a  capable of accommodating the above described entire driven gear  52  therein, an operation portion  53   b  disposed at a predetermined position in a circumferential direction on an outer periphery of this cover portion  53   a , a second engagement portion  53   c  disposed at a shaft center position on a left end face of the cover portion  53   a , and a hook portion  53   d  disposed in the vicinity of this second engagement portion  53   c . A shaft center position on an inner surface of this lock member  53  (right end face of the cover portion  53   a ) can be detachably connected to the shaft connection portion  51   c  on the left end portion of the above described shaft member  51 . Moreover, the second engagement portion  53   c  of the look member  53  can be attached to the above described bearing portion  39  installed on the housing body  2   a  similarly to the above described first engagement portion  51   a  of the shaft member  51 . Moreover, at a predetermined position in the circumferential direction of the cover portion  53   a , an exposing hole  53   e  for exposing a part of a tooth surface of the above described driven gear  52  is disposed. Moreover, in the vicinity of the hook portion  53   d , an exposure hole  53   f  which will be described later in detail is disposed. The second engagement portion  53   c  and the exposure hole  53   f  will be described later in detail (see  FIGS. 19A to 19C  which will be described later). 
     Here, an example of an assembling procedure of the winding core member  40  will be described. That is, when the winding core member  40  is to be assembled, first, the second cylinder portion  47  of the second outer tube  43  is externally inserted through the outer peripheral side of the left end portion of the inner tube  41 . At this time, the paper core  44  is not attached to the outer peripheral side of the second cylinder portion  47  yet, the second outer tube  43  including the second flange portion  48  is movable in the left-and-right direction as described above. While the left end portion of the paper core  44  is brought into contact with a right end face  48   a  of the second flange portion  48  in the second outer tube  43 , the left end portion of the paper core  44  is slightly fitted on the outer peripheral side of the second cylinder portion  47 . At this time, by moving the second outer tube  43  in the left-and-right direction in accordance with a width direction dimension of the paper core  44 , an axial position of the paper core  44  can be determined. When the paper core  44  is completely attached to the outer peripheral side of the second cylinder portion  47 , the second outer tube  43  including the second flange portion  48  is fixed to the outer peripheral side of the inner tube  41  and cannot move in the left-and-right direction. Then, the first outer tube  42  including the first flange portion  46  is detachably attached to the outer peripheral portion on the right end portion of the inner tube  41  where the paper core  44  is present on the outer peripheral side. At this time, the paper core  44  has its right end portion positioned by the first flange portion  46  so that the right end portion is in contact with a left end face  46   a  of the first flange portion  46  in the first outer tube  42 . 
     Moreover, the driven gear  52  is attached to the left end portion of the inner tube  41 , and the driven gear  52  is covered by the lock member  53 . Then, the shaft connection portion  51   c  and the shank portion  51   b  of the shaft member  51  are made to penetrate through the through hole at the shaft center of the inner tube  41  and the driven gear  52  integrally connected, and a tip end of the shaft connection portion  51   c  is detachably connected to an inner surface of the lock member  53 . As a result, the winding core member  40  is assembled (see  FIGS. 18A and 18B ). In this assembled state, the inner tube  41 , the first outer tube  42 , the second outer tube  43 , the paper core  44 , and the driven gear  52  are integrally connected, while the shaft member  51  and the lock member  53  are integrally connected. A torque transmitted to the driven gear  52  is transmitted to the inner tube  41 , the first outer tube  42 , the second outer tube  43 , and the paper core  44  and rotates with respect to the shaft member  51  and the lock member  53 . 
     Subsequently, if the entire winding core member  40  is accommodated in the aforementioned second accommodating portion  4  in a state in which the first engagement portion  51   a  of the shaft member  51  and the second engagement portion  53   c  of the lock member  53  are attached so as to be supported by the above described two bearing portions  39 , respectively, the driven gear  52  is meshed with the driving gear  38 , and the above described adhesive tape  150 ″ with print is taken up. That is, while the adhesive tape  150 ″ with print is sequentially wound on the outer peripheral side of the paper core  44 , the entire winding core member  40  rotates around the axis O 2 . As a result, the adhesive tape  150 ″ with print is sequentially wound and laminated on the outer peripheral side of the paper core  44 , and the second roll R 2  is formed. At this time, in order to smoothen start of a winding operation as above, a leader tape  80  is disposed on the paper core  44  (see  FIG. 17 ). A tip end portion  80   a  having a substantially snakehead shape of the leader tape  80  is extended toward the outside of the paper core  44 . To this tip end portion  80   a , the adhesive layer  152  provided in the adhesive tape  150 ″ with print is bonded and connected. As a result, by rotation of the entire winding core member  40  including the paper core  44  around the axis O 2 , the adhesive tape  150 ″ with print connected to the tip end portion  80   a  of the leader tape  80  is pulled into the paper core  44  side and sequentially wound and laminated on the outer peripheral portion of the paper core  44 , and the second roll R 2  is formed. 
     The winding core member  40  is capable of repeating disassembling and assembling by the unit of all the members including the paper core  44 . As a result, with the rotation of the winding core member  40 , the adhesive tape  150 ″ with print is sequentially introduced into the space between the above described first flange portion  46  and the second flange portion  48 , the adhesive tape  150 ″ with print is laminated on the paper core  44  mounted on the first cylinder portion  45  and the second cylinder portion  47 , and the second roll R 2  is formed and then, the entire winding core member  40  can be disassembled, and only the second roll R 2  can be removed. 
     When the above described winding core member  40  is to be attached to the second accommodating portion  4  of the housing body  2   a , it is desirable that power is reliably transmitted to the drum portion  50  (the inner tube  41 , the first outer tube  42 , and the second outer tube  43 ), operability is high and their structures are simple. Thus, in the present embodiment, the following attachment configuration is provided. 
       FIGS. 19A to 19C  schematically illustrate a process in which the winding core member  40  of the present embodiment is attached to the second accommodating portion  4  of the housing body  2   a .  FIG. 19A  illustrates a state before the winding core member  40  is accommodated,  FIG. 19B  for a state immediately after the winding core member  40  is accommodated, and  FIG. 19C  for a state in which accommodating of the winding core member  40  is locked, respectively, and each figure illustrates only the bearing portion  39  on the housing body  2   a  side, the driving gear  38 , and the winding core member  40 . 
     First, in  FIG. 19A , the bearing portion  39  disposed on the housing body  2   a  (not shown in the figure) has so-called D-cut portions  39   a  at two spots. The D-cut portion  39   a  is a portion in which a part (an arc portion) on an outer peripheral portion is cut so as to form a chord in an axial section of the substantially columnar bearing portion  39 . Though not particularly shown, this D-cut portion  39   a  has a plane formed at a position corresponding to the chord when the shaft member  51  is seen from the side surface. In the present embodiment, in the one bearing portion  39 , the D-cut portions  39   a  are arranged at two spots so as to face each other in point symmetry with respect to its center line. As a result, in the bearing portion  39 , a separation distance between the two D-cut portions  39   a  becomes a minimum diameter Ds, and a diameter between the remaining two arc portions becomes a maximum diameter Db. 
     Moreover, in the second engagement portion  53   c  disposed at the axis position of the lock member  53 , a round hole portion  71  having a diameter substantially equal to the above described maximum diameter Db of the bearing portion  39  and a slot portion  72  communicating with this round hole portion  71  and having a width substantially equal to the above described minimum diameter Ds of the bearing portion  39  are disposed. With such configuration, when the winding core member  40  is to be attached to the housing body  2   a , the bearing portion  39  is fitted in the slot portion  72  of the second engagement portion  53   c  and advances into the round hole portion  71  (see  FIG. 19B ). Subsequently, by the operation of the lock member  53  through the operation portion  53   b , the lock member  53  rotates (swings) around the axis (which is the same as the above described axis O 2  in this example) and then, the bearing portion  39  is fitted in the round hole portion  71  of the second engagement portion  53   c  while relatively rotates in the round hole portion  71  (see  FIG. 19C ). As a result, the bearing portion  39  can no longer be fitted in the slot portion  72  again nor move to the outside of the round hole portion  71 . As described above, the second engagement portion  53   c  of the lock member  53  and the bearing portion  39  are fixed by engagement. A swing direction of the lock member  53  at this time is the same as the rotating direction of the above described driven gear  52 . 
     Though not particularly shown, in the first engagement portion  51   a  provided on the right end portion of the shaft member  51  and the bearing portion  39  corresponding to that, too, the attachment configuration similar to the above is disposed. As described above, since the bearing portion  39  and the lock member  53  are integrally connected through the shaft connection portion  51   c , the swing operation in the lock member  53  interlocks with the first engagement portion  51   a  of the shaft member  51  as it is. In order to attach the first engagement portion  51   a  and the second engagement portion  53   c  to the corresponding bearing portions  39  at the same time, respectively, the circumferential positions of the respective slot portions  72  need to match. The exposed hole  53   e  of the lock member  53  is formed so as to expose the tooth surface of the driven gear  52  with an arc length corresponding to the swing width of the operation portion  53   b  in order to avoid interference of the cover portion  53   a  with a meshed point between the driving gear  38  and the driven gear  52 . 
     Subsequently, as illustrated in  FIG. 19C , by fixing the shaft member  51  to the bearing portion  39  by the lock member  53 , the driven gear  52  is positioned, and thus, the tooth skip at the meshed point (connection portion) between the driving gear  38  and the driven gear  52  can be suppressed. As a result, the power of the driving gear  38  can be reliably transmitted to the drum portion  50 . 
     Moreover, in the present embodiment, in order to fix the winding core member  40  to the second accommodating portion  4  of the housing body  2   a  more reliably, the projecting portion  36  is disposed on the housing body  2   a  and the hook portion  53   d  on the lock member  53 , respectively. 
       FIGS. 20A and 20B  specifically illustrate appearances of a process of locking the projecting portion  36  of the housing body by the hook portion  53   d  of the lock member  53 , in which  FIG. 20A  corresponds to  FIG. 19B  and  FIG. 20B  to  FIG. 19C , respectively. In each figure, the projecting portion  36  fixedly disposed on the housing body  2   a  side is indicated by a broken line. 
     As described above, the projecting portion  36  is disposed in the vicinity of the lower part of the bearing portion  39 . The hook portion  53   d  is formed integrally on the lock member  53  and disposed at a position not interfering with the projecting portion  36  at attachment of the winding core member  40  to the housing body  2   a  (see  FIG. 20A ). When the lock member  53  rotates (swings) around the axis by the operation of the lock member  53  through the operation portion  53   b , the hook portion  53   d  is locked on the lower surface of the projecting portion  36  (see  FIG. 20B ). By this locking of the hook portion  53   d , the shaft member  51  can be fixed to the bearing portion  39  further firmly. 
     Moreover, the projecting portion  36  is formed having a hollow shape as described above, and its opening portion  36   a  is directed toward the winding core member  40  side. Though not particularly shown, an optical sensor combining a light emitting portion and a light receiving portion adjacently is disposed inside the housing body  2   a  (see  FIG. 21  which will be described later), and projection light from the light emitting portion is projected to the winding core member  40 , and its reflection light is received by the light receiving portion. A hollow hole inside the projecting portion  36  becomes a passage hole for the projection light and the reflection light. In accordance with that, the exposure hole  53   f  of the lock member  53  does not overlap with the opening portion  36   a  of the projecting portion  36  at a position before lock of the lock member  53  and shields the projection light (see  FIG. 20A ) and overlaps with the opening portion  36   a  of the projecting portion  36  at a position after lock of the lock member  53  and allows the projection light to pass. As a result, presence of the lock state of the winding core member  40  can be detected by the optical sensor. Moreover, the projection light having passed through the exposure hole  53   f  of the lock member  53  is projected to the driven gear  52 , but since the slit holes  52   c  are disposed at equal intervals in the circumferential direction in the driven gear  52  as illustrated in  FIG. 17 , a so-called rotary encoder is constituted, and the rotation state of the second roll R 2  can be detected. Though not particularly shown, the configuration of this rotary encoder is also disposed on the third roll R 3 . 
     &lt;Control System&gt; 
     Subsequently, a control system of the adhesive tape printer  1  will be described using  FIG. 21 . In  FIG. 21 , a CPU  212  constituting a computing unit executing predetermined calculation is provided in the adhesive tape printer  1 . The CPU  212  is connected to a RAM  213  and a ROM  214 . The CPU  212  executes signal processing in accordance with a program stored in the ROM  214  in advance by using a temporary storage function of the RAM  213  and thereby controls the entire adhesive tape printer  1 . At this time, a control program for executing control processing which will be described later is stored in the ROM  214 . This CPU  212  is connected to a motor drive circuit  218  for executing driving control of the above described feeding motor M 1  driving the above described feeding roller  12 , a motor drive circuit  219  for executing driving control of the above described adhesive take-up motor M 2  driving the above described second roll R 2 , a motor drive circuit  220  for executing driving control of the above described separation sheet take-up motor M 3  driving the above described third roll R 3 , a print-head control circuit  221  for executing charging control of a heating element of the above described print head  11 , and a motor drive circuit  222  for executing driving control of the above described cutter motor M 4  for running the movable blade  32  of the above described cutter mechanism  30 . 
     Moreover, to the CPU  212 , a display portion  215 , an operation portion  216 , two optical sensors  223  and  224  corresponding to the second roll R 2  and the third roll R 3 , respectively, and a PC  217  are connected. 
     The ROM  214  stores print data (dot pattern) such as characters, symbols and the like to be received from the PC  217  and printed, associated with code data, and the CPU  212  creates print data to be printed on a print area of the above described print label L by using this stored print data. The CPU  212  feeds out the print-receiving tape  150  by the feeding roller  12  and produces the adhesive tape by having the print head  11  apply print through the print-head control circuit  217  in accordance with the created print data. 
     &lt;Print Processing Control Contents&gt; 
     Subsequently, by using  FIGS. 22 to 28 , control contents of print processing executed by the CPU  212  of the adhesive tape printer  1  will be described. First, in  FIG. 22 , when power of the adhesive tape printer  1  is turned on by an operator, for example, this flow is started (“START” position). 
     First, at Step S 5 , the CPU  212  makes a selection input of a processing mode by a mode selection operation by a user through the operation portion  216 . 
     Subsequently, at Step S 10 , the CPU  212  determines whether or not the processing mode selected and input at Step S 5  is a preparation mode. If the preparation mode has been selected, the determination is satisfied (S 10 : YES), and the routine proceeds to Step S 100 . 
     At Step S 100 , preparation mode processing for preparing before normal print processing is executed. Then, this flow is finished. 
     On the other hand, in the determination at Step S 10 , if the preparation mode has not been selected, the determination is not satisfied (S 10 : NO), and the routine proceeds to Step S 15 . 
     At Step S 15 , the CPU  212  determines whether or not the processing mode selected and input at Step S 5  is a normal mode. If the normal mode has been selected, the determination is satisfied (S 15 : YES), and the routine proceeds to Step S 200 . 
     At Step S 200 , normal mode processing for executing the normal print processing is executed. Then, this flow is finished. 
     On the other hand, in the determination at Step S 15 , if the normal mode has not been selected, the determination is not satisfied (S 15 : NO), and the routine proceeds to Step S 300 . 
     At Step S 300 , cutting mode processing for cutting the adhesive tape  150 ″ with print after the normal print processing has been executed is executed. Then, this flow is finished. 
     The preparation mode, the normal mode, and the cutting mode will be described below, respectively. 
     &lt;1: Preparation Mode&gt; 
       FIGS. 23A to 23C  schematically illustrate a process of print preparation in the preparation mode. First, the user feeds out the print-receiving adhesive tape  150  from the first roll R 1  and passes the fed-out print-receiving adhesive tape  150  between the feeding roller and the print head  11  (See  FIG. 23A ). During this period, the CPU  212  controls the feeding motor M 1  so that the feeding roller is rotated in the feeding direction only for a predetermined time. 
     Subsequently, the separation material layer is peeled off the print-receiving adhesive tape  150 , and the tip end of the adhesive tape  150 ′ with print formed of the base layer and the adhesive layer is fixed to the winding core of the second roll R 2 . On the other hand, the tip end of the separation material layer peeled off the print-receiving adhesive tape  150  is fixed to the third roll R 3  (See  FIG. 23B ). 
     In this state, the CPU  212  stops the feeding roller only for a predetermined time and controls the feeding motor M 1  and the adhesive take-up motor M 2  so that only the second roll R 2  is rotated in a take-up direction (see  FIG. 23B ). As a result, the adhesive tape  150 ′ with print from which the separation material layer has been peeled off is pulled by the stopped feeding roller and the second roll R 2  rotating in the take-up direction, and at the time when loosening is removed, the rotation of the second roll R 2  is stopped, and a tension works. If the rotation of the second roll R 2  is detected at the time when the tension should be acting on the adhesive tape  150 ′ with print as above, it is considered that the second roll R 2  idles since fixing of the tip end of the adhesive tape  150 ′ with print to the paper core  44  is defective, and nonconformity is reported. 
     Subsequently, the CPU  212  stops the feeding roller only for a predetermined time and controls the feeding motor M 1  and the separation sheet take-up motor M 3  so that only the third roll R 3  is rotated in the take-up direction (see  FIG. 23C ). As a result, the separation material layer peeled off the adhesive tape  150 ′ with print is pulled by the stopped feeding roller and the third roll R 3  rotating in the take-up direction, and at the time when loosening is removed, the rotation of the third roll R 3  is stopped, and a tension works. Moreover, at this time, even if a separation point between the adhesive tape  150 ′ with print and the separation material layer moves by pulling of the adhesive tape  150 ′ with print by the above described rotation only of the second roll R 2 , an original position (a tip end position of the peeling-off portion  17 ) can be restored (see broken line portions in  FIGS. 23B and 23C ). If rotation of the second roll R 2  is detected at the point of time when a tension should be working on the separation material layer as above, it is considered that the third roll R 3  idles since fixing of the tip end of the separation material layer to the third roll R 3  is defective, and nonconformity is reported. 
     Subsequently, the CPU  212  controls the feeding motor M 1 , the adhesive take-up motor M 2 , and the separation sheet take-up motor M 3  so that the feeding roller, the second roll R 2 , and the third roll R 3  are all rotated only for a predetermined time without performing a print operation (though not particularly shown). By performing this preliminary operation, whether a series of operations including feeding-out, feeding, taking up of the print-receiving adhesive tape  150  and taking up of the separation material layer can be performed normally or not can be confirmed in advance. 
     Control contents of the preparation mode processing S 100  executed by the CPU  212  of the adhesive tape printer  1  in order to realize the control contents above will be described by using  FIG. 24 . In the figure, names of the portions are abbreviated as appropriate for convenience of a limited space (the same applies to the following). 
     First, at Step S 105 , the CPU  212  starts driving of the feeding motor M 1 . 
     Subsequently, at Step S 110 , the CPU  212  stands by in a loop until a predetermined time has elapsed since start of driving of the feeding motor M 1  at Step S 105 . The predetermined time for standby in this case may be such that the tip end of the print-receiving adhesive tape  150  fed out of the first roll R 1  is fed from the feeding roller  12  and arrives at the second roll R 2  or the third roll R 3 . When the predetermined time has elapsed, the routine proceeds to Step S 115 . 
     At Step S 115 , the CPU  212  stops driving of the feeding motor M 1 . 
     Subsequently, at Step S 120 , the CPU  212  stands by in a loop until an operation of instructing to resume a work by the user through the operation portion  53   b  is input. If the operation of instructing to resume the work is input, the routine proceeds to Step S 125 . 
     At Step S 125 , the CPU  212  starts driving of the adhesive take-up motor M 2  (abbreviated as AD motor in the figure). 
     Subsequently, at Step S 130 , the CPU  212  stands by in a loop until a predetermined time has elapsed since start of the driving of the adhesive take-up motor M 2  at Step S 125 . The predetermined time for standby in this case may be such that (1 second at the maximum) loosening of the adhesive tape  150 ′ with print from the feeding roller  12  to the second roll R 2  is removed, and an appropriate tension can be made to work. When the predetermined time has elapsed, the routine proceeds to Step S 135 . 
     At Step S 135 , the CPU  212  determines whether or not the second roll R 2  is rotating at this point of time on the basis of detection contents of the optical sensor  223  corresponding to the second roll R 2 . If the second roll R 2  is not rotating, the determination is not satisfied (S 135 : NO), and the routine proceeds to Step S 140 . 
     At Step S 140 , the CPU  212  stops the driving of the adhesive take-up motor M 2 . 
     Subsequently, at Step S 145 , the CPU  212  starts driving of the separation sheet take-up motor M 3  (abbreviated as a separation sheet motor in the figure). 
     Subsequently, at Step S 150 , the CPU  212  stands by in a loop until a predetermined time has elapsed since start of the driving of the separation sheet take-up motor M 3  at Step S 145 . The predetermined time for standby in this case may be such that loosening of the separation material layer from the feeding roller  12  to the third roll R 3  also including the aforementioned pulling back at the separation point is removed, and an appropriate tension can be made to work. When the predetermined time has elapsed, the routine proceeds to Step S 155 . 
     At Step S 155 , the CPU  212  determines whether or not the third roll R 3  is rotating at this point of time on the basis of detection contents of the optical sensor  224  corresponding to the third roll R 3 . If the third roll R 3  is not rotating, the determination is not satisfied (S 155 : NO), and the routine proceeds to Step S 160 . 
     At Step S 160 , the CPU  212  stops the driving of the separation sheet take-up motor M 3 . 
     Subsequently, at Step S 165 , the CPU  212  starts the driving of the feeding motor M 1 , the adhesive take-up motor M 2 , and the separation sheet take-up motor M 3 . 
     Subsequently, at Step S 170 , the CPU  212  stands by in a loop until a predetermined time has elapsed since start of the driving of each of the motors at Step S 165 . The predetermined time for standby in this case may be such that whether the series of operations including feeding-out, feeding, taking up of the print-receiving adhesive tape  150  and taking up of the separation material layer can be performed normally or not can be sufficiently confirmed visually. When the predetermined time has elapsed, the routine proceeds to Step S 175 . 
     At Step S 175 , the CPU  212  stops the driving of the feeding motor M 1 , the adhesive take-up motor M 2 , and the separation sheet take-up motor M 3 . 
     Subsequently, at Step S 180 , the CPU  212  notifies that all the preparation operations have been normally performed, and the preparation mode processing has been finished by displaying the fact on the display portion or the like. Then, this flow is finished. 
     On the other hand, in the determination at Step S 135 , if the second roll R 2  is rotating, the determination is satisfied (S 135 : YES), and the routine proceeds to Step S 185 . 
     At Step S 185 , the CPU  212  stops the driving of the adhesive take-up motor M 2 . 
     Subsequently, at Step S 190 , the CPU  212  considers that the second roll R 2  is idling since fixing of the tip end of the adhesive tape  150 ′ with print to the second roll R 2  is defective and notifies the fact by displaying it on the display portion or the like. Then, this flow is finished. 
     On the other hand, in the determination at Step S 155 , if the third roll R 3  is rotating, the determination is satisfied (S 155 : YES), and the routine proceeds to Step S 195 . 
     At Step S 195 , the CPU  212  stops the driving of the separation sheet take-up motor M 3 . 
     Subsequently, at Step S 198 , the CPU  212  considers that the third roll R 3  is idling since fixing of the tip end of the separation material layer in the third roll R 3  is defective and notifies the fact by displaying it on the display portion or the like. Then, this flow is finished. 
     &lt;2. Normal Mode&gt; 
       FIG. 25  schematically illustrates a process of the normal mode. First, the CPU  212  starts the driving of the feeding motor M 1 , the adhesive take-up motor M 2 , and the separation sheet take-up motor M 3  with the print operation by the print head  11 . If, during the subsequent normal print operation, no rotation is detected by at least either one of the two optical sensors  223  and  224  corresponding to the second roll R 2  and the third roll R 3 , respectively, the CPU  212  determines it to be abnormal. In the normal mode, if rotation of the both second roll R 2  and third roll R 3  is detected by the two optical sensors  223  and  224 , it is normal, and if no rotation is detected by at least either one of the optical sensors  223  and  224 , it is considered to be occurrence of malfunction caused by jamming of the tape or the like, and nonconformity is notified. 
     Control contents of the normal mode processing S 200  executed by the CPU  212  of the adhesive tape printer  1  in order to realize the control contents above will be described by using  FIG. 26 . 
     First, at Step S 205 , the CPU  212  starts the driving of the feeding motor M 1 , the adhesive take-up motor M 2 , and the separation sheet take-up motor M 3 . 
     Subsequently, at Step S 210 , the CPU  212  starts the print by the print head  11 . 
     Subsequently, at Step S 215 , the CUP  212  determines whether or not rotation of the second roll R 2  has stopped on the basis of detection contents of the optical sensor corresponding to the second roll R 2 . If the rotation of the second roll R 2  has not stopped, the determination is not satisfied (S 215 : NO), and the routine proceeds to Step S 220 . 
     At Step S 220 , the CPU  212  determines whether or not rotation of the third roll R 3  has stopped on the basis of detection contents of the optical sensor corresponding to the third roll R 3 . If the rotation of the third roll R 3  has not stopped, the determination is not satisfied (S 20 : NO), and the routine proceeds to Step S 225 . 
     At Step S 225 , the CPU  212  determines whether or not the print has been finished with a scheduled length. If the print has not been finished, the determination is not satisfied (S 225 : NO), the routine returns to Step S 215 , and the similar procedure is repeated. 
     On the other hand, if the print has been finished, the determination is satisfied (S 225 : YES), and the routine proceeds to Step S 230 . 
     At Step S 230 , the CPU  212  stops the print by the print head  11 . 
     Subsequently, at Step S 235 , the CPU  212  stops the driving of the feeding motor M 1 , the adhesive take-up motor M 2 , and the separation sheet take-up motor M 3 . 
     Subsequently, at Step S 240 , the CPU  212  notifies that all the print operations have been normally performed, and the normal mode processing has been finished by displaying the fact on the display portion or the like. Then, this flow is finished. 
     On the other hand, in the determination at Step S 215 , if the rotation of the second roll R 2  has stopped, the determination is satisfied (S 215 : YES), and the routine proceeds to Step S 245 . 
     At Step S 245 , the CPU  212  stops the driving of the feeding motor M 1 , the adhesive take-up motor M 2 , and the separation sheet take-up motor M 3 . 
     Subsequently, at Step S 250 , the CPU  212  considers that the rotation has stopped since the adhesive tape  150 ′ with print of the second roll R 2  is in a jammed state and notifies the fact by displaying it on the display portion or the like. Then, this flow is finished. 
     On the other hand, in the determination at Step S 220 , if the rotation of the third roll R 3  has stopped, the determination is satisfied (S 220 : YES), and the routine proceeds to Step S 255 . 
     At Step S 255 , the CPU  212  stops the driving of the feeding motor M 1 , the adhesive take-up motor M 2 , and the separation sheet take-up motor M 3 . 
     Subsequently, at Step S 260 , the CPU  212  considers that the rotation has stopped since the separation material layer of the third roll R 3  is in a jammed state and notifies the fact by displaying it on the display portion or the like. Then, this flow is finished. 
     &lt;3. Cutting Mode&gt; 
       FIGS. 27A to 27C  schematically illustrate a process of tape cutting in the cutting mode. When the print has been finished through the normal mode, the feeding roller, the second roll R 2 , and the third roll R 3  all stop rotation. Moreover, at this time, since an outer diameter of the second roll R 2  has become larger, a pressing roller  37  is brought into contact with an outer periphery of the second roll R 2  and urges it (see  FIG. 27A ). 
     The feeding motor M 1  and the adhesive take-up motor M 2  are controlled so that the feeding roller is stopped and the second roll R 2  is rotated in the take-up direction. As a result, a portion in the adhesive tape  150 ′ with print which is to be cut is brought into a state in which a tension works by the feeding roller  12  stopped on the upstream side and the second roll R 2  which is to rotate in the take-up direction on the downstream side (see  FIG. 27B ). 
     At this time, the separation sheet take-up motor M 3  is controlled so that the third roll R 3  is also rotated in the take-up direction. Since the third roll R 3  is also to rotate in addition to the second roll R 2 , a stronger tension can be made to work on the adhesive tape  150 ′ with print. Moreover, at this time, even if the separation point (peeling-off position) between the adhesive tape  150 ′ with print and the separation material layer moves to the downstream side by pulling of the adhesive tape  150 ′ with print by the rotation of the above described second roll R 2 , it can be pulled back to the original position (the tip end position of the peeling-off portion  17 ) (see a broken line portion in  FIG. 27B ). 
     In this state, the adhesive tape  150 ′ with print is cut by the cutter mechanism  30  between the feeding roller  12  and the second roll R 2 . As a result, loosening of the adhesive tape  150 ′ with print when the cutter mechanism  30  is brought into contact with the edge portion of the adhesive tape  150 ′ with print can be suppressed, and occurrence of defective cutting can be suppressed (see  FIG. 27B ). 
     Control is made so that the feeding roller  12  is stopped, and the second roll R 2  is rotated in the take-up direction, and then, the adhesive take-up motor M 2  is controlled so that the second roll R 2  is stopped after rotation in the take-up direction for a predetermined time (See  FIG. 27C ). That is, after the cutting of the adhesive tape  150 ′ with print by the cutter mechanism is completed, the second roll R 2  is not stopped immediately but stopped after rotation for a predetermined time. As a result, since the second roll R 2  can be rotated for a predetermined amount after completion of the cutting, a terminal end portion of the adhesive tape  150 ′ with print generated by the cutting can be reliably taken up by the second roll R 2 . Moreover, at this time, since the pressing roller  37  is urged to the outer periphery of the second roll R 2 , the terminal end portion of the adhesive tape  150 ′ with print is reliably taken up in the second roll R 2 . 
     If the rotation of the second roll R 2  is not detected at the time when the terminal end portion of the adhesive tape  150 ′ with print should have been taken up by the second roll R 2  as above, it is considered that cutting by the cutter mechanism  30  is defective and the second roll R 2  is not rotated, and nonconformity is notified. 
     Control contents of the cutting mode processing S 300  executed by the CPU  212  of the adhesive tape printer  1  in order to realize the control contents above will be described by using  FIG. 28 . 
     First, at Step S 305 , the CPU  212  starts the driving of the adhesive take-up motor M 2  and the separation sheet take-up motor M 3 . 
     Subsequently, at Step S 310 , the CPU  212  stands by in a loop until a predetermined time has elapsed since the start of the driving of each of the motors at Step S 305 . The predetermined time for standby in this case may be such that loosening of the adhesive tape  150 ′ with print from the feeding roller  12  to the second roll R 2  is removed, and an appropriate tension can be made to work. Alternatively, the time may be such that loosening of the separation material layer from the feeding roller  12  to the third roll R 3  also including the aforementioned pulling back at the separation point is removed, and an appropriate tension can be made to work. When the predetermined time has elapsed, the routine proceeds to Step S 315 . 
     At Step S 315 , the CPU  212  performs the cutting of the adhesive tape  150 ′ with print by an operation of the cutter mechanism  30  by driving the cutter motor. 
     Subsequently, at Step S 320 , the CPU  212  determines whether or not the second roll R 2  is rotating on the basis of detection contents of the optical sensor corresponding to the second roll R 2 . If the second roll R 2  is rotating, the determination is satisfied (S 320 : YES), and the routine proceeds to Step S 325 . 
     At Step S 325 , the CPU  212  stands by in a loop until a predetermined time has elapsed since the cutting operation of the cutter mechanism  30  at Step S 315 . The predetermined time for standby in this case may be such that loosening of the separation material layer from the feeding roller  12  to the third roll R 3  including the aforementioned pulling back at the separation point is removed, and an appropriate tension can be made to work. When the predetermined time has elapsed, the routine proceeds to Step S 330 . 
     At Step S 330 , the CPU  212  stops the driving of the separation sheet take-up motor M 3 . 
     Subsequently, at Step S 335 , the CPU  212  stands by in a loop until a predetermined time has elapsed since the cutting operation of the cutter mechanism  30  at Step S 315 . The predetermined time for standby in this case may be such that the terminal end portion of the adhesive tape  150 ′ with print generated by the cutting can be reliably taken up by the second roll R 2 . When the predetermined time has elapsed, the routine proceeds to Step S 340 . 
     At Step S 340 , the CPU  212  stops the driving of the adhesive take-up motor M 2 . 
     Subsequently, at Step S 345 , the CPU  212  notifies the fact that the cutting operation has been normally performed, and the cutting mode processing has been finished by displaying it on the display portion or the like. Then, this flow is finished. 
     On the other hand, in the determination at Step S 320 , if the second roll R 2  is not rotating (has stopped), the determination is not satisfied (S 320 : NO), and the routine proceeds to Step S 350 . 
     At Step S 350 , the CPU  212  stops the driving of the adhesive take-up motor M 2  and the separation sheet take-up motor M 3 . 
     Subsequently, at Step S 355 , the CPU  212  considers that the second roll R 2  is not rotating since the cutting by the cutter mechanism  30  is defective and notifies the fact by displaying it on the display portion or the like. Then, this flow is finished. 
     &lt;Effects by the Present Embodiment&gt; 
     As described above, in the present embodiment, the adhesive tape  150 ′ with print on which a desired print is applied is taken up around a winding cylinder by the winding core member  40 . The winding core member  40  has the shaft member  51 , the drum portion  50 , the driven gear  52 , and the lock member  53  and is constituted by being detachably attached to the housing  2 . The driven gear  52  is meshed with the driving gear  38  disposed on the housing  2  when the winding core member  40  is attached to the housing  2 . At this time, by fixing the shaft member  51  to the bearing portion  39  by the lock member  53 , the drum portion  50  and the driven gear  52  are positioned, and tooth skip in the connection portion between the driving gear  38  and the driven gear  52  can be suppressed. As a result, power of the driving gear  38  can be reliably transmitted to the drum portion  50 . 
     Moreover, in the present disclosure, the lock member  53  which can fix the shaft member  51  to the bearing portion  39  is provided not on the housing  2  of the adhesive tape printer  1  but on the winding core member  40 . As a result, it becomes possible to have a structure in which the shaft member  51  swings around the axis (which is the same as the above described axis O 2  in this example) by the operation of the lock member  53 , and the shaft member  51  is fixed to the bearing portion  39  by engagement, for example. Therefore, the shaft member  51  can be firmly fixed to the bearing portion  39  with an easy operation, and thus, the lock function and the operability can be both realized. Moreover, since a mechanism for advancing/retracting the bearing portion  39  including the spring, the slide button and the like is no longer necessary, the structure can be simplified. 
     Moreover, particularly in the present embodiment, the lock member  53  is connected to the shaft member  51 , and the shaft member  51  in the state fitted with the bearing portion  39  is configured capable of swing around the axis. The shaft member  51  has the first engagement portion  51   a  capable of engagement with the bearing portion  39  in the vicinity of the axis by the swing operation of the lock member at least on one end. As a result, by an extremely simple operation like swing of the lock member  53 , the shaft member  51  can be fixed to the bearing portion  39  by engaging the first engagement portion  51   a  of the shaft member  51  with the bearing portion  39 , and thus, operability can be reliably improved. 
     Moreover, the first engagement portion  51   a  of the shaft member  51  is engaged with the bearing portion  39  in the vicinity of the axis. As a result, as compared with engagement at a position away from the axis of the shaft member  51 , the shaft member  51  can be fixed to the bearing portion  39  stably and firmly. 
     Moreover, particularly in the present embodiment, the first engagement portion  51   a  is disposed on the end portion on the one side of the shaft member  51 , and the lock member  53  having the second engagement portion  53   c  is connected to the end portion on the other side. As a result, the shaft member  51  and the lock member  53  can be engaged with the bearing portion  39  on the both end portions in the axial direction. Therefore, as compared with engagement only on the one end side in the axial direction, the shaft member  51  can be fixed to the bearing portion  39  stably and firmly. 
     Moreover, particularly in the present embodiment, the bearing portion  39  is a columnar shaped projection having at least one D-cut portion  39   a , and the first engagement portion  51   a  and the second engagement portion  53   c  have the round hole portion  71  having a diameter substantially equal to the maximum diameter Db of the bearing portion  39  and the slot portion  72  communicating with the round hole portion  71  and having a width substantially equal to the minimum diameter Ds of the bearing portion  39 . With such configuration, when the winding core member  40  is attached to the housing  2 , the bearing portion  39  advances into the round hole portion  71  while it is fitted in the slot portions  72  of the first engagement portion  51   a  and the second engagement portion  53   c . If the lock member  53  and the shaft member  51  swing around the axis by the operation of the lock member  53 , the bearing portion  39  relatively rotates in the round hole portion  71  while it is fitted in the round hole portions  71  of the first engagement portion  51   a  and the second engagement portion  53   c . As a result, the bearing portion  39  can no longer be fitted in the slot portion  72  again or no longer move to the outside of the round hole portion  71 . As described above, the first engagement portion  51   a  of the shaft member  51  and the second engagement portion  53   c  and the bearing portion  39  are fixed by the engagement. 
     In the above described configuration, it is only necessary that the D-cut portion  39   a  is formed on the columnar bearing portion  39 , and the round hole portion  71  and the slot portion  72  are formed in the first engagement portion  51   a  of the shaft member  51  and the second engagement portion  53   c  of the lock member  53 , respectively, and thus, the lock mechanism can be easily realized without particularly increasing components other than the bearing portion  39 , the shaft member  51 , and the lock member  53 . Therefore, complication of the structure can be reliably suppressed. 
     Moreover, particularly in the present embodiment, the lock member  53  has the hook portion  53   d  capable of engagement with the projecting portion  36  disposed on the housing  2  when the second engagement portion  53   c  is engaged with the bearing portion  39  by the swing operation. By locking through this hook portion  53   d , the shaft member  51  can be fixed to the bearing portion  39  further firmly. 
     Moreover, particularly in the present embodiment, the lock member  53  has the cover portion  53   a  covering the driven gear  52 . As a result, occurrence of malfunction caused by adhesion of foreign substances such as dusts to the driven gear  52  can be suppressed, and reliability of the adhesive tape printer  1  can be improved. Moreover, since the lock member  53  has the operation portion  53   b  on the outer periphery of the cover portion  53   a , the operator can easily perform the swing operation of the lock member  53  by using the operation portion  53   b , and operability can be further improved. 
     Moreover, particularly in the present embodiment, there are a plurality of types of the winding core members  40  with different diameters of the drum portion  50 . In the adhesive tape printer  1 , print is applied while the print-receiving adhesive tape  150  is being fed at a constant speed, and thus, if the diameter of the drum portion  50  is relatively small, the drum portion  50  needs to be rotated fast, while if the diameter of the drum portion  50  is relatively large, the drum portion  50  needs to be rotated slowly. 
     In the present disclosure, since the cover portion  53   a  of the lock member  53  has the portion to be detected  81 , the type of the winding core member  40  can be detected by the detection portion  82  disposed on the housing  2  when the winding core member  40  is attached to the housing. As a result, the rotation speed of the above described drum portion  50  can be changed in accordance with the detection result, and malfunction caused by loosening of the tape can be suppressed. 
     In the above, the example in which the present disclosure is applied to the adhesive tape printer  1  applying a print to the print-receiving adhesive tape  150  is described, but this is not limiting, and the present disclosure can be applied to a tape processing apparatus for executing processing to the adhesive tape other than print. 
     Moreover, other than those described above, methods in the above described embodiment and each of the variations may be used in combination as appropriate.
