Description

  The present invention relates to a transfer tool used when transferring a transfer product such as an adhesive, a correction tape, and a pigment onto a sheet or other transfer target surface.

  In this type of transfer tool, a transfer tape to which a transfer product is attached is fed out from a feeding reel, wound around a take-up reel via a transfer head, and the power transmission device rotates the take-up reel and the take-up reel. It is linked via

  When the amount of tape wound around the take-up reel decreases as the transfer material is consumed and the amount of tape wound around the take-up reel increases at the same time, the effective winding diameter of the feed reel decreases, and The substantial winding diameter of the take-up reel is increased. Then, the winding speed of the tape on the take-up reel increases, and the tension of the tape increases.

  In order to prevent such an increase in tension, a sliding mechanism that allows a difference in rotational speed between a feeding-side gear member that is an element of the power transmission device and a shaft support member that supports the feeding reel ( In many cases, a friction clutch mechanism is interposed.

  The sliding mechanism disclosed in the following patent document forms an annular ridge that also serves as a spring retainer in the middle of a shaft portion that extends in the axial direction from the gear member and is inserted into the support shaft member. In addition, a locking claw that engages with the projection on the shaft portion is formed at the opening edge of the support shaft member to prevent the shaft member from coming off, and a compression coil spring is disposed in the gap between the gear member and the support shaft member. . The coil spring exhibits an elastic biasing force that separates the gear member and the support shaft member along the axial direction, strengthens the engagement between the ridges and the locking claws, and generates a friction torque.

  In the known sliding mechanism described above, since the support shaft member is moved away from the gear member, the size of the mechanism along the axial direction tends to be large, which leads to enlargement of the transfer tool main body employing this. It was.

  The present invention made in view of the above is intended to reduce the size of a sliding mechanism that is effectively mounted on a transfer tool.

  The present invention is a transfer tool for winding a transfer tape from a supply reel onto a take-up reel via a transfer transfer head, and interlocking rotation of the supply reel and rotation of the take-up reel via a power transmission device. A sliding mechanism is formed between a gear member that is an element of the power transmission device and a support shaft member that is slidable with respect to the gear member and supports either the supply reel or the take-up reel. The slidable mechanism is provided in the gear member and has a boss shaft part separated from an external tooth part via an annular groove, and is provided in the support shaft member, and has a substantially cylindrical shape continuous in the circumferential direction, The boss shaft portion is inserted between the fitting portion in which at least a part is received in the annular groove and the annular groove and the fitting portion are inserted, and the boss shaft portion is extracted from the fitting portion. It has a retaining structure to prevent To. The support shaft member may be integrated with a supply reel or a take-up reel for winding the tape.

  If it is such, it will become possible to make the dimension of a gear member and a support shaft member, and the dimension of the sliding mechanism which made these a mechanism component as small as possible.

  An inward projecting piece provided in the annular groove and projecting from the inner peripheral surface of the annular groove, and provided in the fitting portion, projecting from the outer peripheral surface of the fitting portion, and the boss shaft portion being inserted into the fitting portion And an outward projecting piece positioned inward along the axial direction of the inward projecting piece, and the retaining structure is constructed by the engagement of the inward projecting piece and the outward projecting piece. If it is a thing, the shape of a gear member and a spindle member will not become complicated easily.

  It is preferable that a plurality of the inwardly projecting pieces are provided intermittently along the circumferential direction, and the outwardly projecting piece has a substantially annular shape continuous in the circumferential direction.

  If the boss shaft portion has a protruding portion protruding from the outer peripheral surface, and the protruding portion and the inward protruding piece are opposed in the radial direction, the protruding portion and the inward protruding piece The fitting portion of the support shaft member can be partly sandwiched and accurately positioned. That is, it is possible to prevent the shaft center of the support shaft member from being greatly deviated from the shaft center of the gear member, and it is possible to more reliably prevent the boss shaft portion from being unexpectedly extracted from the fitting portion.

  When a plurality of the inward projecting pieces are intermittently provided along the circumferential direction, the plurality of the convex portions are also intermittently formed along the circumferential direction.

  If a part of the fitting part is a flange projecting outward from the other part, the inward protruding piece is close to the flange, and the outward protruding piece is provided on the flange. The strength of the fitting portion can be reinforced with the flange to prevent deformation of the fitting portion. Thereby, the possibility that the engagement between the inward projecting piece and the outward projecting piece is unexpectedly reduced is reduced, and the stability as the retaining structure is increased.

  If the fitting portion of the support shaft member has an external dimension that can be inserted into either the feeding reel or the take-up reel, the fitting portion also contributes to the reel support, and the shaft of the transfer tool It can be effective for downsizing the dimension in the center direction.

  The supporting shaft member is configured such that a fitting portion is connected to a proximal end side of a base shaft portion having a smaller diameter than the fitting portion, and a rib protrudes from an outer peripheral surface of the base shaft portion. If the outer peripheral surface of the mounting portion is substantially flush, the operation of inserting and removing the support shaft member from the reel is facilitated.

  According to the present invention, it is possible to reduce the size of a sliding mechanism that is effectively mounted on a transfer tool.

As described above, the stopper portion 63 is a plate-like portion along the peripheral wall portions 312 and 322 of the first and second case members 31 and 32, and the first and second case members 31 and 32 are open at the open position O. The rotational movement of the cap 6 is restricted by hitting it.

  As described above, the cap opening / closing mechanism 7 drives the cap 6 from the closed position C to the opened position O or in the opposite direction in conjunction with the movement of the slide frame 4. Specifically, the cap opening / closing mechanism 7 is provided on the cap drive projection 71 provided on the surface of the face plate portion of the slide frame 4 facing the first case member 31 and the first case member 31 of the slide frame 4.

The cap 6 is driven by pressing and the guide claw 611 of the cap 6 moves in the guide slit 311b, so that the cap 6 moves from the closed position C to the middle between the closed position C and the opened position O. Then, when the slide frame 4 further moves from the intermediate position between the storage position S and the use position U shown in FIG. 9 to the use position U shown in FIG. 10, the driven portion 73 and the cap guide protrusion 72 come into contact with each other. Thus, the cap 6 is driven, and the guide claw 611 of the cap 6 continues to move in the guide slit 311b, so that the cap 6 moves from the middle between the closed position C and the open position O to the open position O. On the other hand, when the slide frame 4 moves from the open position O toward the storage position S, the cap opening / closing mechanism 7 operates in the opposite direction to that described above. That is, when the slide frame 4 moves from the use position U to the intermediate position between the storage position S and the use position U, the driven portion 73 and the cap guide protrusion 72 are brought into contact with each other to drive the cap 6. When the six guide claws 611 move in the guide slit 311b, the cap 6 moves to the middle between the closed position C and the open position O.

Function.

  Then, when turning to the refill 2 again, the refill 2 is supported by the slide frame 4 of the transfer tool main body 1 and the use position U where the transfer head 22 is exposed to the outside integrally with the slide frame 4. The transfer head 22 is movable between the storage position S in which the transfer head 22 is stored in the transfer tool body 1. Further, the refill 2 is provided with an anti-spinning mechanism 25 that prevents rotation of the supply reel 22 when not in use.

  The refill frame 24 is engaged with a supply reel support portion 241 that supports the supply reel 21, a take-up reel support portion 242 that supports the take-up reel 23, and ratchet teeth 23 a provided on the take-up reel 23. It has a ratchet claw 243 for preventing reverse rotation of the take-up reel 23, and a locking arm 244 provided with a locking claw 244x engaged with a locking tooth 21a provided on the feeding reel 21 at the tip. Further, an engagement receiving portion 245 having a long hole 245a is provided at the end of the refill frame 24 on the transfer head 22 side. The engagement receiving portion 245 is formed by housing the engagement pin 412 provided on the slide frame 4 in the long hole 245a inside the engagement receiving portion 245 in a state where the refill 2 is attached to the slide frame 4. The portion 245 and the engagement pin 412 form a movable engagement portion K that supports the refill frame 24 movably on the slide frame 4.

  The feeding reel 21 is provided with a meshing hole 211 at the center for receiving a rotational force from the clutch 44 when the transfer tape is pulled out from the feeding reel support 241 described above. In addition, as described above, the locking teeth 21 a that engage with the locking claws 244 x of the refill frame 24 are provided on the surface of the supply reel 21 that faces the refill frame 24. Further, in this embodiment, the transfer material on the transfer tape is placed on the inner surface, that is, the surface toward the center of the feeding reel 21 in order to reduce the portion where the transfer material is exposed when not used for a long time, such as during transportation or storage. It is wound around the supply reel 21 while being held. Then, the transfer tape fed out from the portion opposite to the transfer symmetry surface of the operation reel 21 is guided to the portion toward the transfer symmetry surface of the take-up reel 23 and guided to the transfer head 22.

  The take-up reel 23 is a main body of the take-up reel 23 and is provided on the take-up reel main body 231 supported by the take-up reel support 242 and the refill frame 24 side of the take-up reel main body 231. There is a ratchet tooth 23a that engages with the ratchet pawl 243, and a take-up gear 232 that is provided on the side of the take-up reel body 231 facing the slide frame 4 and can mesh with the second intermediate gear 46 of the slide frame 4. is doing. The winding gear 232 has a bevel gear shape so that it can be easily meshed with the second intermediate gear 46 when the refill 2 is replaced. In this embodiment, the take-up reel 23 is arranged closer to the transfer head 22 than the supply reel 21.

  As shown in FIGS. 11 and 12, the anti-spinning mechanism 25 engages a locking claw 244 x provided at the tip of the locking arm 244 of the refill frame 24 and a locking tooth 21 a provided on the feeding reel 21. This prevents the refill frame 24 from rotating. More specifically, the locking arm 244 includes an arm main body 244a extending in the longitudinal direction of the refill frame 24, a shaft portion 244b extending from an intermediate portion of the arm main body 244a toward both side edges of the refill frame 24, and a shaft portion 244b. And an elastic support portion 244c extending in a direction toward the transfer head 22 toward the both side edges of the refill frame 24. The arm main body 244a is capable of seesaw movement around a fulcrum 244z set at an intermediate portion. The fulcrum 244z is a portion that strikes against an arm support portion 413 provided so as to protrude from the end of the slide frame 4 on the knock bar 51 side to the refill frame 24 side. In addition, a protrusion 244y that strikes the locking release protrusion 321b provided on the second case member 32 as the refill 2 moves is provided at the end of the arm body 244a on the knock bar 51 side. When the projection 244y hits the locking release projection 321b, the arm body 244a rotates around the fulcrum 244z, and the locking claw 244x is separated from the locking teeth 21a as shown in FIG. When the protrusion 244y of the locking arm 244 hits the locking release protrusion 321b, the locking arm 244 accumulates an elastic force in the direction in which the locking claw 244x and the locking tooth 21a are engaged. The A notch 24x is provided at a portion of the refill frame 24 around the arm main body 244a so that the arm main body 244a can be moved in the thickness direction of the refill frame 24.

  Further, between the refill 2 and the second case member 32, a release mechanism K for releasing the rotation prevention state of the refill 2 by the idling prevention mechanism 25 is provided. The release mechanism K is configured using the protrusion 244y provided on the lock arm 244 and the lock release protrusion 321b provided on the second case member 32. The release mechanism K functions as follows when the transfer tool T is used.

  When the transfer tool T is used, the knock mechanism 5 is operated to move the slide frame 4 and the refill frame 24 supported by the slide frame 4 from the storage position S toward the use position U. At this time, when the refill frame 24 moves to the use position U, the protrusion 244y of the locking arm 244 hits the locking release protrusion 321b of the second case member 32, and the arm body 244a rotates and moves around the fulcrum 244z. As shown in FIG. 13, the locking claw 244 x at the tip of the locking arm 244 is separated from the locking tooth 21 a of the feeding reel 21. As a result, the feeding reel 21 can be rotated.

  On the contrary, when the transfer tool T is not used, the knock mechanism 5 is operated to move the slide frame 4 and the refill frame 24 supported by the slide frame 4 from the use position U toward the storage position S. At this time, when the refill frame 24 moves from the use position U, the state where the protrusion 244y of the locking arm 244 hits the locking release protrusion 321b of the second case member 32 is released. At that time, the arm main body 244a is rotationally moved about the fulcrum 244z by an elastic force, and the engaging claw 244x at the tip of the engaging arm 244 is engaged with the engaging tooth 21a of the feeding reel 21, as shown in FIG. Fit. As a result, the rotation of the feeding reel 21 is restricted again.

  Hereinafter, the sliding mechanism (friction clutch mechanism) 8 formed by the feeding gear 43 and the clutch 44 will be described in detail. When the transfer tool T is used, when the user holds the transfer tool body 1 and moves the transfer tool body 1 while pressing the transfer head 22 and the transfer tape against the transfer target surface, the transfer tape wrapped around the transfer head 22 is transferred. The transfer tape is dragged onto the transfer target surface, and the transfer tape is pulled out from the supply reel 21. The rotational driving force applied from the transfer tape to the feeding reel 21 is transmitted to the clutch 44 that rotates integrally with the feeding reel 21, and further transmitted from the clutch 44 to the feeding gear 43. The feeding gear 43, the first intermediate gear 45, and the second intermediate gear 4646 constituting the power transmission device 9 transmit this rotational driving force to the take-up gear 232. The take-up gear 232 is integrally formed with the take-up reel 23, and the take-up reel 23 that is rotationally driven via the take-up gear 232 takes up the tape on which the transfer object has been transferred.

  When the remaining amount of tape wound around the supply reel 21 decreases and the amount of tape wound around the take-up reel 23 increases at the same time, the substantial winding diameter of the supply reel 21 decreases, and The substantial winding diameter increases. Since the speed increasing ratio (or speed reducing ratio) between the feeding gear 43 and the take-up gear 232 is constant, the tape take-up speed on the take-up reel 23 increases and the tape tension increases.

  In order to prevent such an increase in tension, the clutch 44 is slid with friction with respect to the feeding gear 43 to cause a difference in the rotational speed between the two, and the tape feeding speed of the feeding reel 21 and the take-up reel 23 are made different. The sliding mechanism 8 that matches the tape winding speed is provided. The degree of slipping in the sliding mechanism 8, in other words, the rotational speed difference between the clutch 44 and the feeding gear 43 is 0 or small when the transfer tape is unused, and increases as the transfer tape is used and its remaining amount decreases. Become.

  As shown in FIGS. 14 and 15, the feeding gear 43 includes an outer tooth portion 431 having outer teeth meshing with the first intermediate gear 45 on the outer periphery, and a boss shaft portion extending in the axial direction in the central portion. 432 and an annular groove 433 opened in the axial direction separating the external tooth portion 431 and the boss shaft portion 432. The boss shaft portion 432 has a substantially thick cylindrical shape, but the tip side is notched at a plurality of locations, and is not continuous in the circumferential direction by these notches 432b. In the illustrated example, a plurality of (three) notches 432b are formed, but one notch 432b may be provided. In addition, the outer peripheral surface has a plurality of convex portions 432a intermittently along the circumferential direction. Each convex portion 432 a slightly bulges from the outer peripheral surface of the boss shaft portion 432. The annular groove 433 is provided with a plurality of inwardly protruding pieces 433a intermittently along the circumferential direction. Each inwardly projecting piece 433a extends along the radial direction from the inner peripheral surface of the annular groove 433 (the surface facing the inner side on the outer peripheral side of both the radially opposed walls) so as to narrow the opening width of the annular groove 433. It extends inward and faces each convex part 432a along the radial direction.

  As shown in FIGS. 14 and 16, the clutch 44 includes a base shaft portion 441 and a fitting portion 442 connected to the base end side of the base shaft portion 441. The base shaft portion 441 has a substantially cylindrical shape that is smaller in diameter and longer than the fitting portion 442, and the fitting portion 442 has a substantially cylindrical shape that is larger in diameter and shorter than the base shaft portion 441. Both the base shaft portion 441 and the fitting portion 442 are thinner than the boss shaft portion 432, and are continuous one round without tearing along the circumferential direction. The fitting portion 442 continues to the base shaft portion 441 through a hollow disk-shaped continuous portion 443 that is orthogonal to the axial direction. A part of the fitting portion 442 is a flange 442a that protrudes outward along the radial direction from the other portions. An outward projecting piece 442b projecting from the outer peripheral surface of the flange 442a is provided at the end edge of the flange 442a. The outward projecting piece 442b has a substantially annular shape that is continuous in the circumferential direction. A plurality of ribs 441 a project from the outer peripheral surface of the base shaft portion 441 along the radial direction. Each rib 441 a is joined to the base shaft portion 441 and the continuous portion 443. The outer end surface of each rib 441a has a base end side that is substantially flush with the outer peripheral surface of the fitting portion 442, and a tip end side that is tapered.

  The clutch 44 is assembled to the feeding gear 43 by inserting the boss shaft portion 432 into the fitting portion 442 and simultaneously inserting the flange 442 a of the fitting portion 442 into the annular groove 433. As shown in FIGS. 15 and 17, in a state where the clutch 44 is assembled to the feeding gear 43, the convex portion 432 a of the boss shaft portion 432 is in close contact with the inner peripheral surface of the fitting portion 442. In addition, the inwardly projecting piece 433a of the annular groove 433 approaches or contacts the outer peripheral surface of the fitting portion 442, particularly the outer peripheral surface of the flange 442a. In addition, the distal end surface of the boss shaft portion 432 approaches or comes into contact with the surface on the proximal end side of the continuous portion 443. Further, the outward projecting piece 442b is positioned inward (in the direction toward the proximal end of the boss shaft portion 432, upward in FIG. 17) along the axial direction from the inward projecting piece 433a. A retaining structure that prevents the boss shaft portion 432 from being pulled out of the fitting portion 442 and thus the clutch 44 from being separated from the feeding gear 43 by the engagement of the outwardly projecting piece 442b and the inwardly projecting piece 433a. Is built.

  In the sliding mechanism 8, torque is transmitted by sliding friction between the inner peripheral surface of the fitting portion 442 of the clutch 44 and the convex portion 432 a of the boss shaft portion 432 of the feeding gear 43. The boss shaft portion 432 formed with the notch 432b can be elastically deformed so that the diameter thereof is contracted, and the convex portion 432a is pressed against the inner peripheral surface of the fitting portion 442 by repulsion of the elastic deformation. It is possible to generate a friction torque with a large magnitude. An inward protruding piece 433a protruding from the inner peripheral surface of the annular groove 433 is close to the outer peripheral surface of the fitting portion 442, and the inward protruding piece 433a is relative to the boss shaft portion 432 in the radial direction. Regulate displacement. Therefore, the boss shaft portion 432 is not greatly deformed so as to be plastically deformed, and the durability of the mechanism and the boss shaft portion 432 can be kept from coming off.

  Both the feeding gear 43 and the clutch 44 are pivotally supported on a feeding core 42 formed integrally with the slide frame 4. That is, as shown in FIG. 17, the feeding gear 43 and the clutch 44 are rotated to the slide frame 4 by inserting the feeding core 42 into the inside of the boss shaft portion 432 and the base shaft portion 441 from the feeding gear 43 side. Support as possible. In addition, a portion excluding the base shaft portion 441 of the clutch 44 and the flange 442 a of the fitting portion 442 fits inside the feeding reel 21 on the scissors where the refill 2 is attached to the slide frame 4. The rib 441 a protruding from the base shaft portion 441 of the clutch 44 is engaged with the unevenness of the inner periphery of the feeding reel 21, and plays a role of synchronizing the rotation of the feeding reel 21 and the rotation of the clutch 44.

  According to the present embodiment, the transfer tape is wound around the take-up reel 23 from the pay-out reel 21 via the pay-out transfer head 22, and the power transmission device 9 is used to rotate the pay-out reel 21 and the take-up reel 23. Between the gear member 43 that is an element of the power transmission device 9 and the support shaft member 44 that is slidable with respect to the gear member 43 and supports the feeding reel 21. The sliding mechanism 8 is formed on the boss shaft portion 432 provided on the gear member 43 and separated from the external tooth portion 431 via the annular groove 433, and the support shaft member 44. A fitting portion 442 which is provided and has a substantially cylindrical shape continuous in the circumferential direction, the boss shaft portion 432 is inserted and at least a part of the fitting portion 442 fits in the annular groove 433, the annular groove 433 and the fitting portion 442; Between And a retaining structure for preventing the boss shaft portion 432 from being pulled out from the fitting portion 442. Therefore, the dimensions of the gear member 43 and the support shaft member 44, and the sliding mechanism 8 using these as a mechanical component. It becomes possible to make the dimension of as small as possible.

  An inward projecting piece 433a provided in the annular groove 433 and projecting from the inner peripheral surface of the annular groove 433, and provided in the fitting portion 442, projecting from the outer peripheral surface of the fitting portion 442, and in the fitting portion 442 And an outward projecting piece 442b positioned inwardly along the axial direction with respect to the inward projecting piece 433a in a state where the boss shaft portion 432 is inserted, and the inward projecting piece 433a and the outward projecting piece Since the retaining structure is constructed by the engagement with 442b, the shapes of the gear member 43 and the support shaft member 44 are not complicated.

  The plurality of inwardly projecting pieces 433a are intermittently provided along the circumferential direction, the outwardly projecting piece 442b has a substantially annular shape continuous in the circumferential direction, and the boss shaft portion 432 is extracted from the fitting portion 442. Therefore, the clutch 44 can be prevented from being disengaged from the feeding gear 43.

  Since the boss shaft part 432 has a convex part 432a protruding from the outer peripheral surface, and the convex part 432a and the inwardly projecting piece 433a are opposed in the radial direction, the convex part 432a The fitting portion 442 of the support shaft member 44 can be partially sandwiched by the inwardly projecting piece 433a and can be positioned accurately. That is, it is possible to prevent the shaft center of the support shaft member 44 from being greatly deviated from the shaft center of the gear member 43, and more reliably prevent the boss shaft portion 432 from being unexpectedly pulled out from the fitting portion 442. Can do.

  Along with the plurality of inwardly protruding pieces 433a provided intermittently along the circumferential direction, the plurality of convex portions 432a are also formed intermittently along the circumferential direction, and each inwardly protruding piece 433a is formed. It faces each convex part 432a.

  A part of the fitting portion 442 is a flange 442a projecting outward from the other part, the inward protruding piece 433a is close to the flange 442a, and the outward protruding piece 442b is adjacent to the flange 442a. Accordingly, the strength of the fitting portion 442 can be reinforced by the flange 442a, and deformation of the fitting portion 442 can be suppressed. Thereby, the possibility that the engagement between the inward projecting piece 433a and the outward projecting piece 442b is unexpectedly reduced is reduced, and the stability as the retaining structure is increased.

  Since the fitting portion 442 of the support shaft member 44 has an external dimension that can be inserted into the feeding reel 21, the fitting portion 442 also contributes to the shaft support of the reel 21, and the axial direction of the transfer tool T It can be effective for miniaturization of dimensions.

  The supporting shaft member 44 is configured such that a fitting portion 442 is connected to a proximal end side of a base shaft portion 441 having a smaller diameter than the fitting portion 442, and a rib 441a protrudes from an outer peripheral surface of the base shaft portion 441. Since the outer end surface of 441a and the outer peripheral surface of the fitting portion 442 are substantially flush with each other, the operation of inserting and removing the support shaft member 44 with respect to the reel 21 at the time of refill 2 replacement is facilitated.

  The present invention is not limited to the embodiment described in detail above. To list, in the above embodiment, friction is generated between the inner peripheral surface of the fitting portion 442 of the support shaft member 44 and the convex portion 432a of the outer peripheral surface of the boss shaft portion 432 of the gear member 43. The convex portion 432 a may not be formed on the shaft portion 432, and the wide range of the outer peripheral surface of the boss shaft portion 432 may be brought into sliding contact with the inner peripheral surface of the fitting portion 442.

  The convex portion 432a of the boss shaft portion 432 can be formed into a shape that is expanded along the circumferential direction without being small as shown in FIG. For example, as shown in FIG. 18, the convex portion 432a may be a convex strip extending in the circumferential direction. By setting it as such an aspect, the area which the convex part 432a and the internal peripheral surface of the fitting part 442 contact | abut increases in the circumferential direction. Therefore, the inner peripheral surface of the fitting part 442 is pressed by the small convex part 432a, and the possibility of being locally deformed by plastic deformation with aging is reduced.

  In addition, as shown in FIG. 19, the convex ridges 432 a extending in the circumferential direction may be inclined so as to transition along the axial direction. In other words, when sliding occurs and the support shaft member 44 rotates relative to the payout gear 43, the contact location in contact with the convex portion 432a on the inner peripheral surface of the fitting portion 442 is displaced in the axial direction. Become. Therefore, the plastic deformation or wear of the inner peripheral surface of the fitting portion 442 is further suppressed, the life of the sliding mechanism is extended, and it can be used for a longer period of time.

  The convex part 432a of the boss shaft part 432 may not be intermittent along the circumferential direction, but may be an annular convex line that continues one round.

  In the above embodiment, friction is generated between the inner peripheral surface of the fitting portion 442 of the support shaft member 44 and the inner peripheral surface (the convex portion 432a) of the boss shaft of the gear member 43. Alternatively, the outer peripheral surface of the fitting portion 442 of the support shaft member 44 and the inward projecting piece 433a of the annular groove 433 of the gear member 43 may be brought into close contact with each other to generate friction therebetween.

  It is not essential to form the flange 442 a in the fitting portion 442 of the support shaft member 44. You may make it make the outer peripheral surface of the fitting part 442 which does not have the flange 442a adjoin or contact | abut to the inward protrusion piece 433a.

  The inward projecting piece 433a may be one continuous along the circumferential direction. The outward projecting piece 442b may not be continuous around the circumferential direction but may be partially cut off.

  In the above-described embodiment, the sliding mechanism 8 is disposed on the side of the feeding reel 21 that feeds out the tape. However, a similar sliding mechanism can be disposed on the side of the take-up reel 23 that winds up the tape. In this case, a support shaft member that pivotally supports the take-up reel 23 and a gear member that is assembled with the support shaft member and meshes with the intermediate gear 46 are provided on the take-up reel 23 side.

  In the single-use transfer tool T that does not require refill replacement, it is permitted to integrate the reel 21 around which the tape is wound and the support shaft member 44 that supports the reel 21.

  In addition, the retaining structure that prevents the boss shaft portion 432 from being pulled out from the fitting portion 442 is not limited to the above-described embodiment. For example, as shown in FIG. 20, the inner peripheral surface of the annular groove 433 and the outer peripheral surface of the fitting portion 442 (or the flange 442a forming a part of the fitting portion 442) that is close to or abuts on the inner peripheral surface.
