     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     An embodiment of the present disclosure will be described below by referring to the attached drawings. This embodiment is an embodiment in which a rotary cutter device of the present disclosure is applied to a label producing device as a printer. In the following description, an up-and-down direction, a front-and-rear direction, and a right-and-left direction correspond to arrow directions illustrated as appropriate in each drawing. 
     As illustrated in  FIG. 1 , a label producing device  500  is provided with a label producing device main body  1  and a rotary cutter device  610 . 
     &lt;Configuration of Label Producing Device Main Body&gt; 
     A configuration of the label producing device main body  1  will be described by using  FIGS. 1, 2, 3A and 3B . In  FIGS. 1, 2, 3A and 3B , in order to prevent complexity, a label separating shaft  901 , a label separating plate  902 , a top plate  903  and the like which will be described later are not illustrated. The label producing device main body  1  is composed of a housing  2 , an upper cover  5  made of a transparent resin, a power button  7  arranged on the front side of the housing  2  and the like. 
     As illustrated in  FIG. 3B , a tape holder  3  is accommodated and arranged in a tape holder accommodating part  4  provided in the label producing device main body  1 . Moreover, the above described upper cover  5  is attached to an upper-end edge portion on the rear side capable of being opened/closed so as to cover the upper side of the tape holder accommodating part  4 . 
     Around the tape holder  3 , a label tape  3 A (object to be cut) having a predetermined width is rotatably wound. That is, the label tape  3 A is wound in a roll shape around a winding core  3 B having a predetermined outer peripheral diameter so as to constitute a tape roll. A substantially cylindrical holder shaft member  40  is provided on the inner periphery side of the winding core  3 B so as to be arranged in the axial direction. 
     The label tape  3 A has a three-layer structure in this example (See a partial enlarged view in  FIG. 3B ) and is composed of a separation sheet  3   a , an adhesive layer  3   b , and lengthy thermal paper having self-chromogenic properties (so-called thermal paper)  3   c  laminated in this order from the side wound around the outside of the roller (upper side in the partial enlarged view in  FIG. 3B ) to the opposite side (lower side in the partial enlarged view in  FIG. 3B ). The separation sheet  3   a  is bonded to the back side (upper side in  FIG. 3B ) of the thermal paper  3   c  by the adhesive layer  3   b . This separation sheet  3   a  is configured to be bonded to a desired article or the like by the adhesive layer  3   b  by being separated when a finally completed print label T (See  FIGS. 5 and 6  which will be described later) is attached to the article or the like. 
     Moreover, on the downstream side in a transport direction of a fed-out position from the tape roll of the label tape  3 A, a thermal head  31  for applying desired print is provided, and a platen roller  26  is provided at a position opposite to this thermal head  31 . The platen roller  26  feeds out the label tape  3 A wound around the winding core  3 B and feeds it on a feeding path to a discharging exit E. 
     The thermal head  31  is moved downward by rotating a lever (not shown) for its vertical-movement operation upward and brought into a state spaced away from the platen roller  26  and moved upward by rotating the lever downward and brought into a state capable of print by pressing and biasing the label tape  3 A onto the platen roller  26 . Then, as illustrated in  FIG. 4  which will be described later, by rotating and driving the platen roller  26  by platen roller motor  208  such as a pulse motor (or a stepping motor) by means of driving control of the thermal head  31 , the desired print is applied to a predetermined print area S (See  FIG. 4  which will be described later) provided on the label tape  3 A. Then, the label tape  3 A with print is discharged through the discharging exit E and cut to a predetermined length by the rotary cutter device  610 , whereby the print label T is produced. Broken lines in  FIGS. 1, 3A, and 3B  indicate the feeding path of the label tape  3 A being fed. 
     As illustrated in  FIG. 3A , a guide placing base  700  is installed on the front side of the label producing device main body  1  (on the downstream side in the transport direction from the discharging exit E). The rotary cutter device  610  is arranged further on the downstream side in the transport direction from this guide placing base  700 . The guide placing base  700  leads the label tape  3 A with print discharged through the discharging exit E into a space between a first flat blade  621  (which will be described later) of the rotary cutter device  610  and a second flat blade  631  (which will be described later). 
     &lt;Control System of Label Producing Device Main Body&gt; 
     A control system of the label producing device main body  1  will be described by referring to  FIG. 4 . In  FIG. 4 , the label producing device main body  1  includes a sensor  239  for detecting presence of the label tape  3 A in the feeding path, a printing head driving circuit  205  for controlling electricity supplied to the thermal head  31 , a platen roller motor  208  for driving the platen roller  26 , a platen roller driving circuit  209  for controlling this platen roller motor  208 , and a control circuit  210  for controlling an operation of the entire label producing device main body  1  through the printing head driving circuit  205 , the platen roller driving circuit  209  and the like. 
     The control circuit  210  is a so-called microcomputer and is composed of a CPU which is a central processing unit, a ROM, a RAM and the like, though the details of which are not shown, and executes signal processing in accordance with a program stored in the ROM in advance while using a temporary storage function of the RAM. Moreover, this control circuit  210  is supplied with electricity by a power circuit  211 A and is connected to a communication line, for example, via a communication circuit  211 B so that information can be exchanged with a root server, not shown, connected to this communication line, other terminals, a general-purpose computer, an information server and the like. A motor  638  which will be described later of the rotary cutter device  610  arranged on the front side of the label producing device main body  1  is also driven and controlled by the control circuit  210 . 
     The print label T formed by completion of cutting of the label tape  3 A by the rotary cutter device  610  is illustrated in  FIGS. 5A, 5B, and 6 . As illustrated, the print label T has the above described three-layer structure having the thermal paper  3   c , the adhesive layer  3   b , and the separation sheet  3   a  laminated in this order from the front surface side (upper side in  FIG. 6 ) to the opposite side (lower side in  FIG. 6 ). Then, as illustrated in  FIG. 5A , a print R (here, characters of “AA-AA” in this example) is applied on the surface of the thermal paper  3   c.    
     &lt;Outline Configuration of Rotary Cutter Device&gt; 
     Subsequently, the rotary cutter device will be described by referring to  FIGS. 7-11 . Similarly to the above, in order to prevent complexity in the illustration, the label separating shaft  901 , the label separating plate  902 , the top plate  903  and the like are not illustrated I  FIGS. 7-11 . As illustrated in  FIGS. 7, 8, 9, 10 and 11 , the rotary cutter device  610  is provided with a housing  612 , a rotator  620 , and a holding body  630 . The rotary cutter device  610  performs linear cutting by means of collaboration between the first flat blade  621  (rotary blade) and the second flat blade  631  (fixed blade) on the label tape  3 A on which the print is formed by the thermal head  31 . The housing  612  has a first wall surface  613  on one side (right side in this example) and a second wall surface  614  on the other side (left side in this example). Moreover, the housing  612  is provided with a connection part  611  connecting the first wall surface  613  and the second wall surface  614  to each other. 
     As illustrated in  FIGS. 1 and 2 , the rotary cutter device  610  is arranged with surface directions of the first wall surface  613  and the second wall surface  614  of the housing  612  inclined slightly to the left side from the vertical direction, but for convenience of explanation and ease of understanding the illustration, the housing  612  is illustrated with a posture returned to the vertical direction in  FIGS. 8A and 9B . 
     &lt;Configuration of Rotator&gt; 
     The rotator  620  is provided with a first bracket  622  on one side, a second bracket  623  on the other side, a rotary shaft  650  (rotary shaft member) provided so as to connect the first bracket  622  and the second bracket  623  to each other and rotatably on the housing  612  around a rotation axis O, and a flat-blade mounting part  624  provided on the rotary shaft  650  and attached with the first flat blade  621  as a rotary blade. 
     The first flat blade  621  is provided with a first blade edge part  621   b  extending linearly on an edge portion of a first base part (not shown) having a substantially plate shape. At this time, the first blade edge part  621   b  is, as illustrated in  FIGS. 8A, 9B  and the like, supported by the flat-blade mounting part  624  and the rotary shaft  650  so as to be parallel with the rotation axis O. When the rotator  620  rotates, the first blade edge part  621   b  draws a cylindrical rotation trajectory r (corresponding to a rotation range. See  FIG. 15  which will be described later) around the rotation axis O. 
     &lt;Configuration of Holding Body&gt; 
     The holding body  630  has a plate-shaped holding part  632  provided with the second flat blade  631  as a fixed blade. Moreover, the holding part  632  is provided with extending parts  634  and  634  on the both right and left end portions and is supported by a swing support mechanism  635  (See  FIG. 8B ) through the extending parts  634  and  634  capable of swing with respect to the housing  612 . 
     The swing support mechanism  635  is provided with a pair of right and left hinge arms  641  and  641  installed upright on the connection part  611  of the housing  612 , a support shaft  636  to the both ends of which the extending parts  634  of the holding part  632  are fixed, and a coil-shaped coil spring  637  arranged around the support shaft  636 . The holding part  632  is made capable of swing to the front and rear with respect to the housing  612  by having the support shaft  636  fixed to the extending parts  634  and  634  supported rotatably by the hinge arms  641 . At this time, as illustrated in  FIG. 8A , one end (rear end) of the coil spring  637  is fixed to the connection part  611 , while the other end (upper end) of the coil sprint  637  is brought into contact with a rear portion of the holding part  632 , and as a result, the coil spring  637  biases the holding part  632  to the front (in other words, in a reaction toward the rotator  620 ). As a result, the holding part  632  is supported capable of swing with respect to the housing  612 . 
     The second flat blade  631  is, as illustrated in  FIG. 9B  and the like, provided with a substantially plate-shaped second base part  631   a  and a second blade edge part  631   b  extending linearly on the edge portion of this second base part  631   a . The second flat blade  631  is held by the holding part  632  having the second base part  631   a  fixed by a mounting screw  633 . At this time, the holding part  632  is arranged capable of swing as described above, and the holding part  632  holds the second flat blade  631  so that the second blade edge part  631   b  of the second flat blade  631  is not in parallel (skew position) with the rotation axis O in any swing state. In detail, in any swing state of the holding part  632 , the planar direction of the second base part  631   a  of the second flat blade  631  (that is, the mounting surface direction of the second flat blade  631 ) is in parallel with the rotation axis O with a predetermined interval (See  FIGS. 9A and 9B ). Moreover, in any swing state of the holding part  632 , the second flat blade  631  is disposed such that a straight line including the second blade edge part  631   b  and the rotation axis O form a predetermined angle α as illustrated in  FIG. 9B  when seen from the front (in other words, when seen from the side face direction orthogonal to the planar direction of the second base part  631   a ). Since the rotation axis O and the first blade edge part  621   b  are in parallel with each other all the time, an inclination angle (so-called shear angle) formed when the first blade edge part  621   b  and the second blade edge part  631   b  are brought into contact with each other matches this angle α. Particularly, the second blade edge part  631   b  is held so as to extend linearly in a feeding surface of a feeding path of the label tape  3 A during the cutting operation. 
     As the result of the above, the first flat blade  621  is supported by the flat-blade mounting part  624  so that the cylindrical rotation trajectory r drawn by the first blade edge part  621   b  when the rotator  620  rotates is in contact with the second blade edge part  631   b , while the second flat blade  631  is held by the holding part  632 . As a result, such a positional relationship is formed that the second blade edge part  631   b  of the second flat blade  631  becomes oblique to an outer edge line of the cylindrical rotation trajectory r around the rotation axis O. 
     In this embodiment, as illustrated in  FIG. 10A , the rotator  620  and the holding body  630  are arranged so that the feeding path of the label tape  3 A (in other words, the second blade edge part  631   b ) becomes horizontal and the rotation axis O of the rotator  620  is inclined with respect to the horizontal direction, but this is not limiting. That is, as illustrated in  FIG. 10B , the rotator  620  and the holding body  630  may be arranged so that, when seen from the front side, the rotation axis O of the rotator  620  becomes horizontal and the feeding path of the label tape  3 A (in other words, the second blade edge part  631   b ) is inclined with respect to the horizontal direction. 
     &lt;Transmission of Driving Force&gt; 
     On the other hand, as illustrated in  FIGS. 7, 8A, 8B, 9A, and 9B , the motor  638  functioning as the rotation driving unit rotating and driving the rotator  620  is provided below the second wall surface  614  side of the housing  612 . In correspondence with that, a driving transmission mechanism  639  formed of a gear train capable of operating and connecting between a driving shaft  651  of the motor  638  (See  FIG. 8B ) penetrating the second wall surface  614  and the rotary shaft  650  of the rotator  620  penetrating the second wall surface  614  is provided on an outer surface of the second wall surface  614 . The motor  638  rotates the rotator  620  via the driving transmission mechanism  639  in a direction where the first blade edge part  621   b  of the first flat blade  621  is approaching the second blade edge part  631   b  of the second flat blade  631  from above (See  FIG. 11B ). As a result, the label tape  3 A inserted between the rotator  620  and the holding body  630  is cut in the running state (without stopping the feeding). 
     At this time, as illustrated in  FIG. 9 , a rotation cam  800  having a substantially D-shape when seen on a side view is fixed to one end (left end in this example) of the rotary shaft  650  of the first rotator  620 . As illustrated in  FIGS. 11A and 11B , a contacted part  640  having a projecting piece shape is formed on an upper end portion located on the left side of the second blade edge part  631   b  in the second flat blade  631 . This contacted part  640  is pressed into contact and engaged with the rotation cam  800  in the swing state by a biasing force of the coil spring  637 . 
     The rotation cam  800  is, as illustrated in  FIGS. 11A and 11B , provided with a first circumferential region (corresponding to an arc portion of the D-shape)  801  and a second circumferential region (corresponding to a linear portion of the D-shape)  802 . The rotation cam  800  presses the contacted part  640  to the rear by the first circumferential region  801  at a rotation position where the first circumferential region  801  is opposed to the contacted part  640 . As a result, the rotation cam  800  moves the holding body  630  so that the second blade edge part  631   b  separates from the rotation trajectory of the entire first rotator  620 . On the other hand, the rotation cam  800  is brought into a non-contact state with the contacted part  801  (by means of friction between the first blade edge part  621   b  of the first flat blade  621  which will be described later and the second blade edge part  631   b  of the second flat blade  631 ) in a state where the second circumferential region  802  is opposed to the contacted part  640  and releases the holding body  630  (state illustrated in  FIG. 11B ). 
     &lt;Cutting Operation&gt; 
     An operation of the rotary cutter device  610  will be described by referring to  FIG. 12 . As described above, in this embodiment, such a positional relationship is formed that the second blade edge part  631   b  of the second flat blade  631  becomes oblique to the outer edge line of the cylindrical rotation trajectory r around the rotation axis O drawn by the first blade edge part  621   b  when the rotator  620  rotates. As a result, in the first blade edge part  621   b  having rotated on the rotation trajectory r, one end portion (left end portion in this example) of the linear shape approaches the second blade edge part  631   b  first and then, a portion approaching the second blade edge part  631   b  gradually moves linearly to the right from the left end portion.  FIGS. 12A-12E  sequentially illustrate the behavior at this time. 
     That is,  FIG. 12A  illustrates a state in which a portion expressed by an R 1 -R 1 section close to the left end portion of the first blade edge part  621  is brought into contact with and rubbed by the second blade edge part  631   b  (See a white arrow). For convenience of explanation, a posture of the rotator  620  (rotation angle) in this state is assumed to have a rotation phase of “0°”. 
     After that, in  FIG. 12B  in which rotation of the rotator  620  has progressed, a portion expressed by an R 2 -R 2  section slightly shifted to the right side from the R 1 -R 1  section of the first blade edge part  621  is brought into contact with and rubbed by the second blade edge part  631   b  (See a white arrow). The rotation phase of the rotator  620  at this time is “4°”, for example. 
     After that, in  FIG. 12C  in which rotation of the rotator  620  has further progressed, a portion expressed by an MID-MID section at the center portion in the right-and-left direction slightly shifted to the right side from the R 2 -R 2  section of the first blade edge part  621  is brought into contact with and rubbed by the second blade edge part  631   b  (See a white arrow). The rotation phase of the rotator  620  at this time is “8°”, for example. 
     After that, in  FIG. 12D  in which rotation of the rotator  20  has further progressed, a portion expressed by an L 2 -L 2  section slightly shifted to the right side from the MID-MID section of the first blade edge part  621  is brought into contact with and rubbed by the second blade edge part  631   b  (See a white arrow). The rotation phase of the rotator  620  at this time is “12°”, for example. 
     After that, in  FIG. 12E  in which rotation of the rotator  620  has further progressed, a portion expressed by an L 1 -L 1  section close to the right end portion and slightly shifted to the right side from the L 2 -L 2  section of the first blade edge part  621  is brought into contact with and rubbed by the second blade edge part  631   b  (See a white arrow). The rotation phase of the rotator  620  at this time is “16°”, for example. 
     By introducing the label tape  3 A to a contact portion between the first blade edge part  621   b  and the second blade edge part  631   b  gradually moving as described above, after the cutting into the label tape  3 A on the left end portion is started, the label tape  3 A can be gradually cut ahead linearly to the right. At this time, since the above described angle a functions as a shear angle, cutting can be smoothly accomplished with a relatively small shearing force. 
     &lt;Essential Part of this Embodiment&gt; 
     In the above described configuration, the essential part of this embodiment is that the label tape  3 A adhering to the first blade edge part  621   b  by the adhesive layer  3   b  is peeled off during cutting of the label tape  3 A described above so as to ensure a smooth cutting operation. The details will be described below by referring to  FIGS. 13-15 . 
     &lt;Label Separating Shaft, Label Separating Plate, and Top Plate&gt; 
     As illustrated in  FIGS. 13A-13C , in this embodiment, the label separating shaft  901  (rotation-side separating member) is extended between the first bracket  622  on one side and the second bracket  623  on the other side in the rotator  620  provided with the first flat blade  621 . At this time, this label separating shaft  901  is arranged so as to rotate with a delay of a predetermined delay phase angle (approximately 90° in this example) from the first flat blade  621  (See also  FIG. 13C  and  FIG. 15  which will be described later). 
     Moreover, the label separating plate  902  (fixed-side separating member) is fixed to the housing  612  so as to be outside of the rotation trajectory r which is a rotation range of the first blade edge part  621   b . This label separating plate  902  is extended between the first wall surface  613  and the second wall surface  614  of the housing  612  so as to be in the vicinity of a rotation radius of the first blade edge part  621   b.    
     Moreover, the top plate (receiving member)  903  is provided at a position closer to the rotation advancing side (upper part of the housing  612  in this example) than the position of the label separating plate  902  outside the rotation trajectory r which is the rotation range of the first blade edge part  621   b  and in the rotation direction of the rotator  620 . The top plate  903  is extended between the first wall surface  613  and the second wall surface  614  of the housing  612 . 
     &lt;Comparative Example&gt; 
     Subsequently, a working effect on the basis of a configuration of each of the above described label separating shaft  901 , the label separating plate  902 , and the top plate  903  will be described by referring to a comparative example.  FIGS. 14A-14H  sequentially illustrate a tape feeding/cutting behavior along a rotation angle in the comparative example in which the shaft  901 , the label separating plate  902 , and the top plate  903  are not provided. A value of the rotation phase on the basis of the above described rotation phase “−20°” is indicated in each figure. In order to eliminate complexity in the illustration, reference numerals of constituent members are given only in  FIG. 14A , while only the reference numeral of the label tape  3 A is given and the other reference numerals are omitted in the other  FIGS. 14B-14H . 
     First,  FIG. 14A  illustrates a state in which the rotation phase of the rotator  620  is “−20°”. At this timing, the first blade edge part  621   b  is in a substantially horizontal state and has not arrived at the position of the second blade edge part  631   b  yet. 
       FIG. 14B  illustrates a state in which the rotation phase of the rotator  620  is “0°”, and the first blade edge part  621   b  is in contact with and rubbed with the second blade edge part  631   b  from the upper side so as to sandwich the label tape  3 A in a stable state in which preparation for cutting is complete. As a result, cutting of the label tape  3 A is started. After the cutting with the rotation phase of “0°” is started, rubbing between the first blade edge part  621   b  and the second blade edge part  631   b  is performed until the rotation phase reaches approximately “16°” as described above, and linear cutting is made on the label tape  3 A. 
       FIG. 14C  illustrates a state in which rotation of the rotator  620  has progressed a little from the above described state and the rotation phase of the rotator  620  is “60°”. The label tape  3 A is provided with the adhesive layer  3   b  as described above. As a result, the adhesive in the adhesive layer  3   b  is exposed from a cut surface during cutting with the rotation phase of “0° 0 ”, and the exposed adhesive causes an end portion (cut portion) of the label tape  3 A at a cutting position CP to adhere to the first blade edge part  621   b . As a result, the label tape  3 A on the front in the transport direction (right side in the illustration) from the cut portion (that is, a cut object which becomes the print label T. The same applies to the following) is suspended in a cantilever state with respect to the first blade edge part  621   b  and rotates in the rotating direction together with the first flat blade  621  in that state as illustrated in  FIG. 14C . At the same time, the (subsequent) label tape  3 A located on the rear of the cut position is also fed to the front (right side in the illustration) and introduced into the inside of the rotation trajectory r of the first blade edge part  621   b.    
       FIG. 14D  illustrates a state in which rotation of the rotator  620  has further progressed a little and the rotation phase of the rotator  620  is “120°”. The adhering label tape  3 A (cut object) keeps on rotating while accompanying the first flat blade  621 . The (subsequent) label tape  3 A located on the rear of the cut position is further fed to the front (right side in the illustration). 
     Similarly,  FIG. 14E  illustrates a state in which rotation of the rotator  620  has further progressed a little and the rotation phase of the rotator  620  is “200°”,  FIG. 14F  illustrates a state in which rotation of the rotator  620  has further progressed a little and the rotation phase of the rotator  620  is “230°”,  FIG. 14G  illustrates a state in which rotation of the rotator  620  has further progressed a little and the rotation phase of the rotator  620  is “260°”, and  FIG. 14H  illustrates a state in which the rotation phase of the rotation of the rotator  620  is “360°”. As illustrated in these figures, the adhering label tape  3 A (cut object) is rotating once together with the first flat blade  621  to the rotation phase of “360°” while accompanying the first blade edge part  621   b . As a result, the cutting operation of the first flat blade  621  on the subsequent label tape  3 A which is a cutting target at the time illustrated in  FIG. 14H  and moreover, the cutting operation of the first flat blade  621  after that are affected. 
     &lt;Behavior of Embodiment&gt; 
       FIGS. 15A-15G  sequentially illustrate feeding/cutting behaviors of the label tape  3 A in this embodiment provided with the label separating shaft  901 , the label separating plate  902 , and the top plate  903  along the above described rotation angle. Similarly to the above, in order to eliminate complexity in the illustration, reference numerals of constituent members are given only in  FIG. 15A , while only the reference numeral of the label tape  3 A is given and the other reference numerals are omitted as appropriate in the other  FIGS. 15B-15H . 
     First, the states with the rotation phases “−20°”-“120°” illustrated in  FIGS. 15A-15D  are similar to the above described  FIGS. 14A-14D . That is, the first blade edge part  621   b  is brought into contact with and rubbed with the second blade edge part  631   b  from the upper side, and the cutting of the label tape  3 A is started. During the cutting, since the end portion (cut portion) of the label tape  3 A adheres to the blade edge of the first flat blade  621 , the label tape  3 A (cut object) on the front in the transport direction (right side in the illustration) from the cut position rotates together with the first flat blade  621  in the rotating direction. A first side  621   c  of the first blade edge part  621   b  faces the direction of rotation and a second  621   d  of the first blade edge part  621   b  is opposite to the first side. 
     In this embodiment, in a state where rotation of the rotator  620  has progressed a little from the state illustrated in  FIG. 15D  (corresponding to a predetermined rotating direction position described in each of the claims), the label separating shaft  901  rotates with a predetermined delay phase angle (90°, for example) from the first flat blade  621 , and the label separating shaft  901  is brought into contact with the label tape  3 A (cut object) from inside in the radial direction (See  FIG. 15E  which will be described later). As a result, the label separating shaft  901  gives a reaction force to the outside in the radial direction (See an arrow A in  FIG. 15E  which will be described later) to the label tape  3 A (cut object) adhering as above and rotating with the first flat blade  621 . This state in which the reaction force is applied by the label separating shaft  901  continues until the adhesion is released as will be described above. 
       FIG. 15E  illustrates a state in which rotation of the rotator  620  has further progressed a little and the rotation phase of the rotator  620  is “260°”. In this state, the label separating plate  902  is brought into contact with the label tape  3 A (cut object) from the outside in the radial direction. At this time, the label tape  3 A (cut object) adhering to the first blade edge part  621   b  as described above will move to the outside in the radial direction by means of pressing by the label separating shaft  901 . However, since the label separating plate  902  is brought into contact with the label tape  3 A (cut object) from the outside in the radial direction as described above, subsequent movement to the outside in the radial direction of the label tape  3 A (cut object) is constrained by the label separating plate  902  (See an arrow B in  FIG. 15E ). As a result, as illustrated in  FIG. 15E , the shape of the label tape  3 A (cut object) from the adhesion portion with the first blade edge part  621   b  to the contact portion (constrained portion) with the label separating plate  902  via the contact portion (reaction force applied portion) with the label separating shaft  901  becomes an arched shape expanding to the outside in the radial direction. 
     At this time, as illustrated in  FIG. 15E , the label separating shaft  901  is provided so as to be located on the rotator  620  outside in the radial direction of a plane Q connecting an adhesion portion AP 1  between the first blade edge part  621   b  and the label tape  3 A (cut object) and a contact portion AP 2  between the label separating plate  902  and the label tape  3 A (cut object) when the label separating plate  902  is brought into contact with the label tape  3 A (cut object) from the outside in the radial direction. 
       FIG. 15F  illustrates a state in which rotation of the rotator  620  has further progressed a little and the rotation phase of the rotator  620  is “270°”. As a result of the formation of the arched shape, a deflection repulsion force to escape from constraint of the label separating plate  902  described above is accumulated in the label tape  3 A (cut object) with progress of the rotation after  FIG. 15E , and the repulsion force to the outside in the radial direction acts on the cut portion (that is, the adhesion portion AP 1  to the first blade edge part  621   b . See  FIG. 15E ) of the label tape  3 A. In the state illustrated in  FIG. 15F , the deflection repulsion force exceeds the adhesion force at the adhesion portion AP 1 , whereby the adhesion is released. In this state, the end portion (cut portion) of the label tape  3 A whose adhesion to the first blade edge part  621   b  is released as above is received by the top plate  903 . As described above, the label tape  3 A (cut object) is separated from the first blade edge part  621   b  of the first flat blade  621 . 
       FIG. 15G  illustrates a state in which rotation of the rotator  620  has further progressed a little and the rotation phase of the rotator  620  is “300°”. The label tape  3 A (cut object) released from the adhesion as above and repelling to the outside in the radial direction is received by the top plate  902  and then, separates downward from the top plate  902 . After this state, as rotation of the rotator  620  further progresses, it enters the state before the cutting is started illustrated in  FIG. 15A , and the same procedure is repeated. 
     In the above, the feeding speed of the label tape  3 A and the circumferential speed of the first blade edge part  621   b  are set substantially equal, but this is not limiting. That is, if the label tape  3 A is to be cut to a relatively small length, for example, the circumferential speed of the first blade edge part  621   b  may be set larger than the feeding speed of the label tape  3 A. 
     The present disclosure is not limited to the above described embodiment but is capable of various variations in a range not departing from its gist and technical idea. The variations will be described below in order. 
     (1) If delay phase angle of label separating shaft is set small: 
     In this variation, the delay phase angle of the label separating shaft  901  from the first flat blade  621  is set smaller than that in the above described embodiment (to less than 10°, for example, in this example). That is, as illustrated in  FIGS. 16A-16G , the label separating shaft  901  is arranged relatively close to the side opposite to the rotating direction of the first flat blade  621 . 
       FIGS. 16A-16G  sequentially illustrate the feeding/cutting behaviors of the label tape  3 A provided with the label separating shaft  901  according to this variation along the above described rotation angle. The same reference numerals are given to the portions equal to those in the above described embodiment. Similarly to the above, in order to eliminate complexity in the illustration, reference numerals of constituent members are given only in  FIG. 16A , while only the reference numeral of the label tape  3 A is given and the other reference numerals are omitted in the other  FIGS. 16B-16H . 
     First, since  FIGS. 16A-16D  illustrate behaviors substantially equal to those in  FIGS. 15A-15D  in the above described embodiment, explanation will be omitted. In a state in which rotation of the rotator  620  has progressed a little (corresponding to the predetermined rotating direction position described in each of the claims) from the state illustrated in  FIG. 16D , the label separating shaft  901  rotates with a predetermined delay phase angle (however, a small value less than 10° in this example) from the first flat blade  621  and thus, is brought into contact with the label tape  3 A (cut object) from inside in the radial direction (See  FIG. 16E  which will be described later). As a result, the label separating shaft  901  applies a reaction force to the outside in the radial direction to the label tape  3 A (cut object) adhering to and rotating with the first flat blade  621  (See an arrow C in  FIG. 16E  which will be described later). This state in which the reaction force is applied by the label separating shaft  901  continues until the adhesion is released as will be described above. 
       FIG. 16E  illustrates a state in which rotation of the rotator  620  has further progressed a little from the above and the rotation phase of the rotator  620  is “200°”. In this state, the label separating plate  902  is brought into contact with the label tape  3 A (cut object) from the outside in the radial direction. The label tape  3 A (cut object) still adhering to the first blade edge part  621   b  will move to the outside in the radial direction by means of pressing by the label separating shaft  901 . Similarly to the above, since the label separating plate  902  is brought into contact with the label tape  3 A (cut object) from the outside in the radial direction at the time, subsequent movement of the label tape  3 A (cut object) to the outside in the radial direction is constrained by the label separating plate  902  (See an arrow D in  FIG. 16E ). As a result, as illustrated in  FIG. 16E , the shape of the label tape  3 A (cut object) from the adhesion portion with the first blade edge part  621   b  to the contact portion AP 2  with the label separating plate  902  via the contact portion with the label separating shaft  901  becomes an arched shape expanding to the outside in the radial direction. 
       FIG. 16F  illustrates a state in which rotation of the rotator  620  has further progressed a little from the above and the rotation phase of the rotator  620  is “230°”. As a result of the formation of the arched shape, similarly to the above, a deflection repulsion force to escape from constraint of the label separating plate  902  described above is accumulated in the label tape  3 A (cut object) with progress of the rotation after  FIG. 16E , and the repulsion force to the outside in the radial direction acts on the cut portion (that is, the adhesion portion AP 1  to the first blade edge part  621   b . See  FIG. 16E ) of the label tape  3 A. 
     After that, in the state illustrated in  FIG. 16G  in which rotation of the rotator  620  has further progressed a little from the above and the rotation phase of the rotator  620  is “240°”, the deflection repulsion force exceeds the adhesion force at the adhesion portion AP 1 , whereby the adhesion is released. In this state, the end portion (cut portion) of the label tape  3 A whose adhesion to the first blade edge part  621   b  is released as above is received by the top plate  903 . As described above, in this variation, too, the label tape  3 A (cut object) is separated from the first blade edge part  621   b  of the first flat blade  621  by means of the method similar to that in the above described embodiment. 
     In this variation, too, the same effects as those in the above described embodiment are obtained. That is, due to the constraint by collaboration of the pressing contact of the label separating shaft  901  and the label separating plate  902 , the deflection repulsion force is accumulated in the label tape  3 A (cut object). When the rotator  620  reaches a given rotating direction position and the deflection repulsions force exceeds the adhesion force at the adhesion portion, the label tape  3 A can be easily separated from the first blade edge part  621   b . As a result, a smooth subsequent cutting operation can be ensured. 
     (2) If rotation-side separating member is composed by using film: 
     That is, as illustrated in  FIG. 17 , a film member  901 ′ bent having a substantially a-shape is used as a rotation-side separating member (instead of the above described label separating shaft  901 ) in this variation. At this time, the bent portion in the film member  901 ′ becomes a distal end part  962 ′, and base parts  961 ′ on the both sides sandwiching this distal end part  962 ′ is fixed to the rotary shaft  650 . The distal end part  962 ′ is brought into contact with the label tape  3 A (cut object) from the inside in the radial direction similarly to the above and presses it to the outside in the radial direction. By using such film member  901 ′, too, the same effects as those with the label separating shaft  901  in the above described embodiment can be obtained. 
     (3) If rotation-side separating member is composed by using a wire or the like: 
     That is, as illustrated in  FIG. 18 , a support structural body  901 ″ using a wire (or a piano wire or the like) as a rotation-side separating member (instead of the label separating shaft  901 ) is used in this variation. That is, the support structural body  901 ″ is composed of two arm-shaped base parts  961 ″ provided in the radial direction at symmetric positions of the rotary shaft  650  and a wire  962 ″ extending between the two base pars  961 ″ and fixed through fixtures  962   a ″. The wire  962 ″ is brought into contact with the label tape  3 A (cut object) from the inside in the radial direction and presses it to the outs de in the radial direction. By means of such support structural body  901 ″, too, the same effects as those with the label separating shaft  901  in the above described embodiment can be obtained. 
     (4) Others 
     In the above, the example was explained in which the present disclosure is applied to the rotary cutter device  610  configured such that the planar direction of the second base part  631   a  of the second flat blade  631  is made parallel with the rotation axis O with a predetermined interval, and a straight line including the second blade edge part  631   b  and the rotation axis O are arranged having the predetermined angle α when seen from the side face direction orthogonal to the planer direction of the second base part  631   a , but this is not limiting. That is, the present disclosure may be applied to the rotary cutter device  610  having the rotator  620  having a flat-blade mounting part  624  arranged at a position spaced away from the rotation axis O on the plane crossing the rotation axis O and arranged with inclination with respect to the rotation axis O so that the radial dimension of the rotation trajectory by an end portion on one side is larger than the radial dimension of the rotation trajectory by an end portion on the other side and a flat-blade support part for supporting the first flat blade  621  with respect to the flat-blade mounting part  624  so that an end portion on one side and an end portion on the other side form rotation trajectories having the same diameters by having the end portion on the other side of the first flat blade  621  corresponding to the other side of the flat-blade mounting part  624  provided protruding largely in the peripheral direction than the end portion on one side of the first flat blade  621  corresponding to one side of the flat-blade mounting part  624 , and the holding body  630  is provided with the holding part  632  capable of holding the second flat blade  631  so as to be substantially parallel with the rotation axis O with a predetermined interval. 
     In the rotary cutter device  610  with the above described configuration, too, the end portion on one side of the first flat blade  621  and the end portion on the other side of the first flat blade  621  form the rotation trajectories having the same diameters, and as a result, the first flat blade  621  of the rotator  620  rotates keeping substantially the same distance from the rotation axis O over the whole region from one side to the other side. Therefore, by introducing the label tape  3 A at a position spaced away by a predetermined distance which is the same from the rotation axis O, substantially linear cutting can be made on the label tape  3 A over the whole region from one side to the other side of the first flat blade  621 . By providing the label separating shaft  901  and the like similar to the above in such rotary cutter device  610 , the same effects as those in the above can be obtained. 
     In the above, the print label T was produced by applying print on the label tape  3 A and cutting it, but this is not limiting. That is, the present disclosure may be applied to a method of producing the print label T by bonding a tape with print as the label tape  3 A on which print has been applied to the base tape and by cutting the bonded tape (so-called laminate type). In this case, too, the same effects are obtained. 
     In the above, arrows illustrated in  FIG. 4  indicate an example of flows of signals and are not intended to limit the flow directions of the signals. 
     Moreover, other than those already described above, the above described embodiment and methods according to the variations may be combined as appropriate and used. 
     Though not specifically exemplified, the present disclosure is put into practice with various changes within the range not departing from its gist.
