  The present invention includes a transport roller for transporting a sticky note, a sticky note supply device that peels off a sticky note from a stack of sticky notes in which a large number of sticky notes are stacked, and prints the supplied sticky note. It relates to a sticky note printer to be applied.

  As a sticky paper printer having a sticky paper supply device, it has a transport roller (friction roller) that transports the sticky paper, and the transport roller lifts the sticky paper from the sticky paper bundle one by one in the sticky paper supply device and peels it off (For example, see Patent Documents 1 to 5).

JP 2003-11436 A JP 2003-11437 A JP 2003-81455 A JP 2003-81457 A JP 2003-212367 A

  However, in any of the transport rollers described in the above patent documents, the sticky paper is transported by the transport roller because the pasted portion of the sticky paper is exposed after the sticky paper is once peeled from the sticky paper bundle. In some cases, the surface of the transport roller sticks to the surface of the apparatus having the transport roller, and the sticky note paper may be caught.

  Therefore, the present invention provides a transport roller that can reliably prevent the sticky paper from sticking and being caught in the apparatus or the like even if the glued portion of the sticky paper is exposed, and a sticky note paper having such a transport roller It is an object of the present invention to provide a supply device and a sticky note printer having such a sticky note supply device.

  In order to solve the above-mentioned problem, the transport roller according to the present invention is (a) rotated to the topmost sticky note among a stack of sticky note papers in which a large number of sticky note papers, each of which is partly glued so that one end is peeled off, are rotated. A transfer roller that contacts and separates the sticky note paper from the bundle of sticky note papers and carries the sticky note paper on the roll surface of the roller body, and (b) the roll surface has a non-adhesive structure Features.

  According to the transport roller, since the roller surface of the roller body has a structure that is difficult to adhere to the glued portion of the sticky note paper, the sticky note paper is stuck even when the glued portion of the sticky note paper is exposed during transport. In addition, it can be prevented from being caught in the apparatus around the transport roller.

  In yet another aspect of the present invention, the roll surface of the roller body is characterized in that the adhesive force of the glued portion of the sticky note paper is smaller than the bending rigidity of the sticky note paper. In this case, even if the sticky paper adheres to the roll surface of the roller body, the adhesive portion loses the rigidity of the sticky paper when the sticky paper is sent out, so that the glued portion can be reliably separated from the roll surface.

  In still another aspect of the present invention, the roll surface of the roller body is subjected to a surface treatment with a non-sticky coating agent. In this case, the separation property from the roll surface of the glued portion can be sufficiently enhanced.

  According to still another aspect of the present invention, the roll surface of the roller body has an uneven shape. In this case, by having an uneven shape on the roll surface, the area of the contact portion in direct contact with the glued portion of the roll surface can be reduced and the adhesive force with the glued portion can be sufficiently weakened.

  According to still another aspect of the present invention, the roll surface of the roller body is formed of silicone rubber. In this case, the roll surface is relatively easily peeled even when it comes into contact with the glued portion.

  In order to solve the above problems, a sticky note supply device according to the present invention includes: (a) a sticky note holder that detachably holds a sticky note bundle; and (b) separating sticky notes from the sticky note bundle of the sticky note holder. A transfer roller according to any one of the above. In this case, by including any one of the above-described transport rollers, it is possible to prevent the sticky note paper from sticking and being caught in an unintended portion when the sticky note paper supply device transports the sticky note paper.

  In order to solve the above problems, a sticky note printer according to the present invention includes: (a) the sticky note supply device; and (b) a sticky note printing device that performs printing on the sticky note supplied from the sticky note supply device. It is characterized by providing. In this case, by providing one of the above-described transport rollers, it is possible to prevent the sticky note paper from sticking to an unintended portion when the sticky note paper is transported by the transport roller in the sticky note printer.

[First Embodiment]
Hereinafter, with reference to the drawings, a transport roller according to the first embodiment, a sticky paper supply device including the transport roller, and a sticky paper printer including the sticky paper supply device will be described in detail.

[A. Overview of the structure of a sticky note printer)
A sticky note printer 1 according to this embodiment shown in FIG. 1 or the like is connected to, for example, a personal computer (hereinafter referred to as a personal computer), and various data such as characters, figures, and contents of e-mails created and selected by the personal computer are used as sticky notes. To be printed. For this reason, as shown in FIG. 1, the sticky note printer 1 can be connected to a personal computer by an interface unit IF, and the control unit 50 built in the sticky note printer 1 receives a control signal from the personal computer, Based on this control signal, the operation of the thermal head 28, the drive motor 51, etc. (see FIG. 2) incorporated together with the control unit 50 is controlled.

  As shown in FIGS. 1 to 3, this sticky note printer 1 includes a printer main body 3 having an outer case formed by an apparatus case 2 and a sticky note bundle 4 as a print target set in the printer main body 3. . The bundle of sticky notes 4 is obtained by laminating a plurality of congruent sticky notes 4a shown in FIGS. 4 (A) and 4 (B) by pasting a part of the back base end side at the same position. . The sticky note 4a is configured to be peelable from the sticky note bundle 4 one by one, and after peeling, the adherend such as paper is attached via the glued portion 4b of the back surface RS of the sticky note 4a. It is comprised so that reattachment is possible. Here, a non-glued portion other than the glued portion 4b in the back surface RS of the sticky note 4a is defined as a non-glued portion 4c.

  Returning to FIG. 1, the device case 2 is formed in a small size as a whole, with a sticky note introduction opening 5 for introducing the sticky note bundle 4 into the case from below and a printed sticky note at the front center. A horizontal slit-like sticky note discharge port 6 for feeding the paper 4a out of the case is formed. A ribbon cartridge 8 (see FIG. 3) in which the ink ribbon R is accommodated is mounted on the upper surface of the apparatus case 2, and an open / close lid 7 for maintenance is attached to be openable and closable.

  This sticky note printer 1 lifts the top sticky note 4a one by one from the sticky note bundle 4 introduced and set through the sticky note introduction opening 5, and prints the sticky note while peeling it from the glued portion 4b. In addition to being sent to the apparatus 12, printing is performed on the ink ribbon R via the ink ribbon R, and the paper is discharged from the sticky note paper discharge port 6 with the printing surface facing up.

  As shown in FIG. 2, inside the device case 2 of the printer main body 3, a sticky note holder 11 for setting a sticky note bundle 4 and a sticky note holder 4 that is positioned above the sticky note holder 11 are printed on the sticky note paper 4 a. The sticky note printing device 12 to be performed and the sticky note paper 4a are lifted and peeled one by one from the sticky note bundle 4 held by the sticky note holder 11 by the rotation of the pickup roller 52 described later, and the sticky note printing device 12 is attached with a sticky note. A sticky note feeder 13 that feeds the paper 4a and discharges it from the sticky note outlet 6 is supported.

  The sticky note holder 11 includes a rectangular set stage 21 on which the sticky note bundle 4 is placed horizontally, an introduction guide 22 that guides the set stage 21 to be slidable in the vertical direction, and a set stage 21 via a biasing member 24. It is comprised with the cover body 23 which supports this from the lower side. After the set stage 21 is inserted into the introduction guide 22, the lid 23 is fixed to the lower surface of the introduction guide 22 and closes the sticky note introduction opening 5 in this state.

  The introduction guide 22 positions the longitudinal direction of the sticky note bundle 4 set on the set stage 21. Note that four engagement protrusions 39 corresponding to the four support engagement holes 18 formed in the sub-frame 15 are formed on the left and right side surfaces of the introduction guide 22, whereby the sticky note bundle 4 is set. The attached sticky note holder 11 is fixed inside the apparatus case 2.

  Before and after the upper opening of the introduction guide 22, a pair of position restricting portions 26 that relatively press the front end portion (free end side) and the rear end portion (glue portion 4 b side) of the sticky note bundle 4 are formed. That is, the position restricting unit 26 sandwiches the sticky note bundle 4 with the set stage 21 and restricts the position so that the uppermost sticky note 4a is always in a fixed position.

  An urging member 24 is disposed between the set stage 21 and the lid body 23, and the urging member 24 includes four pressure springs 24a fixed at both ends to the four corners of the set stage 21 and the like. ing. By the four pressure springs 24a, the set stage 21 is urged upward in a well-balanced manner by receiving the lid body 23. For this reason, even if the sticky note bundles 4a are fed out one by one and diminished, the height level of the sticky note 4a located at the top is always maintained at a fixed position.

  2 and 3, the sticky note printer 12 includes a partial frame 27 fixed to the main frame 14 inside the apparatus case 2, a thermal head 28 fixed integrally with the partial frame 27, and the ribbon described above. A ribbon take-up mechanism 29 for taking up the ink ribbon R of the cartridge 8; The thermal head 28 includes a head main body 30 and a head holder 31 (see FIG. 3) that supports the head main body 30. The ribbon take-up shaft 40 and a pickup roller 52, which will be described later, work together to convey the ink ribbon R and the sticky note 4a sandwiched between the pickup roller 52 and the thermal head 28 in the same direction. , Characters and the like are printed on the sticky note 4a.

  Hereinafter, preparation for printing will be described. First, the sticky note printer 1 and a personal computer (not shown) are connected to each other via an interface unit IF (see FIG. 1) that is a USB or cable. As a result, the sticky note printer 1 enters a communication connection state with the personal computer. Next, the sticky note bundle 4 is positioned by the set plate 25 and placed on the set stage 21 and set in the device case 2 of the sticky note printer 1. Further, the ribbon cartridge 8 is mounted by opening / closing the open / close lid 7. At this time, the head opening of the ribbon cartridge 8 is guided to the thermal head 28 and the ribbon take-up reel 49 is engaged with the ribbon take-up shaft 40. As a result, the sticky note printer 1 enters a print standby state.

  Next, the sticky note supply device 13 will be described. The sticky note supply device 13 holds the drive motor 51 as a drive source, the above-described pickup roller 52, the reduction gear train 53 that transmits rotational power from the drive motor 51 to the pickup roller 52, and the pickup roller 52 so as to be rotatable. And a pick-up unit 54 for moving this up and down.

  The drive motor 51 is supported on the rear portion of the main frame 14. A worm gear 57 and a pulse disc 58 located on the tip side of the worm gear 57 are fixed to the output shaft of the drive motor 51. The pulse disk 58 and a photo interrupter 59 fixed on the drive motor 51 side constitute an encoder, and the heat generation drive of the thermal head 28 is controlled based on a pulse signal detected by the encoder.

  As shown in FIG. 3, the pickup roller 52 as a transport roller faces the front end side (free end side) of the sticky note bundle 4 from above, and a roller shaft 61 supported by the pickup unit 54 at both ends, A roller body 62 that is rotatably attached to the roller shaft 61 and directly contacts the sticky note 4a, and a roller gear 63 (see FIG. 2) that is provided on the opposite side of the roller shaft 61 and rotates together with the roller body 62. Has been. Here, the roller shaft 61 extends in parallel with the thermal head 28 and is supported by the pickup unit 54 in a both-sided manner. The roller body 62 is disposed close to one half of the roller shaft 61, and a resinous core portion 64 that is rotatably attached to the roller shaft 61, and a rubber roll 65 that is wound around the outer peripheral surface of the core portion 64. It consists of

  Of the roller body 62, the rubber roll 65 is surface-treated with a non-sticky coating agent. For example, as shown in FIG. 4C, a roll surface 65a as a surface including a contact portion 65b that directly contacts the sticky note 4a. The entire surface is subjected to surface treatment with a fluorine-based coating agent. Thereby, the roll surface 65a is in a state in which the separation property from the gluing portion 4b is enhanced, and it is relatively easy to peel off even if it contacts the gluing portion 4b of the sticky note 4a. In this case, the pick-up roller 52 serves as a transport roller that sends out the back surface RS of the sticky note 4 in contact with the roll surface 65a, and has either an adhesive gluing portion 4b or a non-adhesive non-gluing portion 4c. Smooth delivery is possible even in the part. Accordingly, it is possible to prevent the sticky note 4a from sticking and being caught in an unintended part (for example, the subframe 15 or the introduction guide 22) in the sticky note printer 1 during conveyance by the pickup roller 52.

  Note that the pickup roller 52 has not only a function of conveying the sticky note 4 a but also a function of rolling on the sticky note 4 a and rolling it up, and a function of a platen roller by cooperating with the thermal head 28. For this reason, the roll surface 65a of the rubber roll 65 in the pickup roller 52 generates the friction necessary for performing the operation of lifting up the sticky note 4a in relation to the surface of the sticky note 4a. . In addition, since the pickup roller 52 functions as a platen roller, the surface treatment layer of the roll surface 65a is maintained, for example, in a substantially uniform thickness of the fluorine-based coating agent so as not to affect the printing operation. I'm leaning.

  In the above description, the entire surface of the roll surface 65a of the rubber roll 65 is subjected to a surface treatment with a fluorine-based coating agent, but at least a contact portion 65b of the roll surface 65a that directly contacts the sticky note 4a is subjected to the surface treatment. Thus, sticking of the sticky note 4a can be prevented. That is, it is only necessary that the surface treatment be performed within a local range in the axial direction of the roll surface 65a. In the above, a fluorine-based coating agent is used as an example of a difficult-to-adhere adhesive coating agent, but from the adhesive type of the sticky note paper used, processability, durability, cost, etc., Teflon (registered trademark) system, It is also possible to select appropriately including a silicone type and the like.

  The roller gear 63 of the pickup roller 52 shown in FIG. 2 is formed integrally with the core portion 64 of the roller body 62. As the roller gear 63 receives rotational power from the drive motor 51 via the reduction gear train 53, the roller body 62 of the pickup roller 52 is driven to rotate counterclockwise in FIG.

  The reduction gear train 53 includes a small transmission gear 66 (worm wheel and small spur gear), a medium transmission gear 67, and an input gear 68. The pin shafts of these gears are fixed to the main frame 14 in a cantilever manner. ing. The power of the drive motor 51 is transmitted in the order of the worm gear 57, the small transmission gear 66, the medium transmission gear 67, and the input gear 68, and rotates the roller body 62 of the pickup roller 52 via the roller gear 63.

  A cam mechanism (not shown) is disposed on the end face of the input gear 68 on the main frame 14 side so as to overlap the input gear 68. The cam mechanism converts the rotation operation of the input gear 68 into the operation of the pickup unit 54.

  The pickup unit 54 holds the roller body 62 of the pickup roller 52 at both ends so as to be rotatable at both ends, and a pair of rotation arms 70 configured to be rotatable around a base end portion, and the pickup roller 52. And a connecting arm 71 that integrally connects the tip ends of the pair of rotating arms 70. The pair of rotating arms 70 includes a pickup arm 72 rotatably supported by the shaft portion 55 of the main frame 14 and another pickup arm 73 rotatably supported by the upper end shaft portion 19 of the subframe 15. It consists of and.

  A support spring 75 for biasing the roller shaft 61 (pickup roller 52) upward is interposed between the arms 72 and 73 and the roller shaft 61. The pickup roller 52 is supported so as to be slightly movable relative to the pickup unit 54, so that the thermal head 28 can be elastically pressed in the abutting direction. Further, when a cam mechanism (not shown) associated with the input gear 68 is operated to the pickup arm 72, the pickup arms 72 and 73 are rotated by being transmitted with power in the rotation direction. That is, when the pickup arm 72 rotates, the pickup roller 52 rotates, that is, moves up and down while maintaining a parallel horizontal posture.

[B. Overview of transport roller operation)
Hereinafter, a series of operations of the pickup roller 52 which is a transport roller will be described with reference to FIGS. 5 (A) to 5 (H). First, as shown in FIG. 5A, in the print standby state, the pickup roller 52 is pressed against the surface of the uppermost sticky note 4a of the sticky note bundle 4 with a pressure of a predetermined level or more. Next, as shown in FIG. 5 (B), when the pickup roller 52 starts to rotate by driving and starts the sticky note roll-up operation, only the uppermost sticky note 4a (the free end side thereof) is positioned on the leading end side. It is pulled out from the part 26, and it bends so that the intermediate part of the longitudinal direction may curve upwards gradually.

  Next, as shown in FIG. 5C, when the pickup roller 52 is rotated and separated from the sticky note bundle 4, the sticky note 4 a immediately after the tip of the sticky note 4 a passes below the pickup roller 52. Is repelled upward and rides on the pickup roller 52.

  The pick-up roller 52 on which the sticky note 4a is placed moves while rotating and revolving to the printing position as shown in FIG. 5D, and as shown in FIG. 5E, the thermal head 28 and the guide roller 32 The sticky note 4a is held between the two. At the same time, the sticky note printing apparatus 12 enters an operating state. Then, as shown in FIG. 5F, the pickup roller 52 performs printing in cooperation with the thermal head 28 while feeding the sticky note paper 4a away from the glued portion 4b.

  As shown in FIG. 5G, the sticky note 4a completely peeled off during printing is further sent out from the printed portion toward the sticky note discharge port 6 by the pickup roller 52 and the guide roller 32. go. When the printed sticky note 4a is sent to the outside from the sticky note discharge port 6, the pickup roller 52 returns from the printing position to the print standby state at the next timing as shown in FIG.

  In the above operation, when the sticky note 4a is sent out by the pickup roller 52 and the guide roller 32, the pasting portion 4b and the roll surface 65a of the pickup roller 52 on the back surface RS which is the side having the pasting portion 4b of the sticky note 4a. Are in contact with each other. At this time, the contact portion 65b between the roll surface 65a of the pickup roller 52 and the glued portion 4b of the sticky note 4a is subjected to a surface treatment with a fluorine-based coating agent, thereby improving the separation property of the glued portion 4b from the contact portion 65b. Can do. More specifically, the adhesive force between the contact portion 65b and the pasting portion 4b is set to be smaller than the bending rigidity of the sticky note 4a. As a result, when the sticky note 4a is sent out, the adhesive force at the glued portion 4b loses the rigidity of the sticky note 4a, and the glued portion 4b is separated from the roll surface 65a. As described above, it is possible to prevent the sticky note 4a from sticking to the pickup roller 52 and being caught in an unintended portion (for example, the subframe 15 or the introduction guide 22) in the sticky note printer 1.

  In addition to the above, various modifications can be considered to prevent the sticky note 4a from sticking to the pickup roller 52 and being caught inside the sticky note printer 1.

  First, for example, as shown in FIG. 6 (A), a very fine textured uneven shape is provided on the roll surface 65a, or a large number of finely cut in a certain direction as shown in FIG. 6 (B). It is good also as what further reduces the adhesive force of the contact part 65b and the gluing part 4b by reducing the area of the contact part 65b by forming the groove | channel GT. In the case where the uneven shape is provided, the size and depth of the unevenness are set so as not to affect the printing operation.

  Further, as the material of the rubber roll 65, for example, normal silicone rubber or the like can be used. However, as the material of the rubber roll 65, a non-adhesive silicone rubber that is relatively easily peeled even when contacting the glued portion 4b is used. May be. In this case, the surface of the roll surface 65a is not subjected to surface treatment with a fluorine-based coating agent, and the silicone rubber can be exposed. Note that whether or not the uneven shape is provided on the roll surface 65a may be determined as appropriate depending on the adhesiveness with the glued portion 4b of the silicone rubber to be used.

  Further, for example, by having an uneven shape such as a satin shown in FIG. 6A, the area exposed as the contact portion 65b of the silicone rubber is reduced, and the adhesiveness with the glued portion 4b is sufficiently suppressed. It may be.

  In the above-described embodiment, the rotation operation by the motor drive is performed by operating a pickup roller 52 as shown in FIG. 5A or the like by a mechanical mechanism. However, the operation of the pickup roller 52 is controlled electronically. It is good also as what is performed by. In this case, it is possible to cause the pickup roller 52 to perform an operation equivalent to the above by a control signal from the control unit 50 of FIG.

[Second Embodiment]
Next, a sticky note printer having a transport roller according to the second embodiment will be described with reference to FIG. In the present embodiment, the pick-up roller 52 that is a transport roller does not serve as a platen roller, but mainly lifts up, peels off, and feeds the sticky note paper 4a, and attaches the sticky note paper 4a to the platen roller 132 provided separately. Is configured to deliver. In addition, the sticky note 4a can be fed in an idle manner. That is, the sticky note printer of this embodiment also functions as a simple dispenser that does not print on the sticky note 4a. In this embodiment, the operation of the pickup roller 52 is performed by electronic control by the control unit 50 of a drive mechanism (not shown) that operates the pickup roller 52.

  As shown in FIGS. 7 and 8, the sticky note printer 101 according to the present embodiment includes a sticky note holder 11, a sticky note printing device 12 that includes a platen roller 132, and a sticky note supply device 13 that includes a pickup roller 52. In addition, the manual operation lever 85 includes a contact / separation unit 90 that causes the platen roller 132 to contact and separate from the thermal head 28. The sticky note printer 1 also includes a detection sensor (detection means) 96 that detects that the platen roller 132 is separated from the thermal head 28.

  The separation / contact means 90 includes a manual operation lever 85 for separating / displacement of the platen roller 132 between the printing position PP and the separation position EP, and a support member 86 connected to the manual operation lever 85 and supporting the platen roller 132. The base end portion of the support member 86 is pivotally supported by a rotation support shaft 87 fixed to the apparatus case 2.

  The support member 86 is pulled up by a biasing force that rotates clockwise by a return spring (not shown) so that the platen roller 132 faces the printing position PP in a printing standby state. The manual operation lever 85 includes a lever main body 91 provided so as to extend upward at the distal end portion of the support member 86, and an operation button portion 92 provided on the upper end surface of the lever main body 91. When the operation button unit 92 is pressed by the user, the support member 86 is rotated counterclockwise about the rotation support shaft 87 and the platen roller 132 is moved from the printing position PP to the separation position EP. It is locked by a lock member (not shown) (see FIG. 9B). When the pivot arm 70 returns from the clamping position 45 to the pickup position 44, the lock member is released and the return spring acts to move the platen roller 132 to the printing position PP.

  The detection sensor 96 is provided below the support member 86, and is configured by a micro switch. When the support member 86 is moved downward via the manual operation lever 85, the lower end surface of the support member 86 comes into contact with the tip of the detection sensor 96, and it is detected that the platen roller 132 has moved to the separation position EP. Further, when the control unit 50 detects that the platen roller 132 has moved to the separation position EP by the detection sensor 96, the control unit 50 does not drive the sticky note printing device 12 but drives only the sticky note supply device 13. For this reason, the sticky note 4a is transported without printing on the sticky note 4a peeled off by the sticky note supply device 13.

  Hereinafter, with reference to FIGS. 9A to 9G, a series of operations relating to the idle feeding of the sticky note 4a will be described. First, as shown in FIG. 9A, in the print standby state, the pickup roller 52 is pressed against the surface of the uppermost sticky note 4a of the sticky note bundle 4. Next, as shown in FIG. 9B, when the user depresses the manual operation lever 85 and the platen roller 132 is moved to the separation position EP by the detection sensor 96, the pickup roller 52 is rotated to rotate the sticky note 4a. Starts the roll-up operation. The control unit 50 interrupts the power to the ribbon take-up shaft 40 in conjunction with the depression of the manual operation lever 85. Next, as shown in FIG. 9C, the free end of the sticky note 4 a rides on the pickup roller 52 due to the rotational force of the pickup roller 52. Further, as shown in FIG. 9D, when the pickup roller 52 on which the sticky note 4a is placed moves to the holding position 45 and the sticky note 4a is held between the follower roller 133, the rolled up sticky note 4a Is peeled off from the sticky note bundle 4. As shown in FIG. 9E, the peeled sticky note 4 a is conveyed toward the sticky note discharge port 6 by the pickup roller 52 and the platen roller 132. Then, as shown in FIG. 9F, when the glued portion 4b of the sticky note 4a reaches the platen roller 132, the pickup roller 52 is moved from the holding position 45 to the pickup position 44 as shown in FIG. Move to. At the same time, the platen roller 132 faces the printing position PP, and sandwiches the glue portion of the sticky note 4a. Thereafter, when the user removes the sticky note 4a discharged to the sticky note discharge opening 6, it is possible to obtain the preliminarily sent sticky note 4a.

  Also in the sticky note printer 101 of the present embodiment, the surface of the roll surface 65a of the pickup roller 52 that is the transport roller of the sticky note supply device 13 is subjected to a surface treatment with a fluorine-based coating agent. As a result, there is no difference in the state in which the sticky paper 4a is sent out when the roll surface 65a is in contact with the glued portion 4b and when the roll surface 65a is in contact with the non-glued part 4c. The sticky paper 4a can be prevented from sticking to the pickup roller 52 and being caught in the sticky paper printer 101 even if it is peeled off and the glued portion 4b is exposed. Furthermore, in this embodiment, the platen roller 132 which is a transport roller different from the pickup roller 52 is also in contact with the gluing portion 4b. Therefore, the roll surface 132a of the platen roller 132 can be subjected to the same treatment as the surface treatment with the fluorine-based coating agent. Thereby, the adhesive force with the glue portion 4b can be made relatively weak, and the sticky note paper 4a can be prevented from sticking to the platen roller 132 and being caught in the sticky note printer 101. In this case, for example, in the state of FIG. 9G, the platen roller 132 may be sandwiched with the thermal head 28 with a force that prevents the sticky note 4a from falling off.

  Further, in addition to the surface treatment with the fluorine-based coating agent on the roll surfaces 65a and 132a, by providing an uneven shape as shown in FIG. 6A, or by using a non-sticky silicone rubber as the material of the rubber roll 65, etc. The adhesive force between the contact portion 65b and the pasting portion 4b may be weakened.

[Other modifications]
