  The present invention pays attention to the above points, and an object of the present invention is to prevent idling of the supply reel and the take-up reel at the time of transportation and the like without requiring the trouble of attaching and detaching the rotation stopper.

  That is, the transfer tool of the present invention is a transfer tool comprising a transfer tool main body and a refill that is mounted on the transfer tool main body and has a pay-out reel and a take-up reel. An anti-spinning mechanism that prevents rotation of at least one of the reels, and a release mechanism that releases the anti-rotation state by the anti-spinning mechanism in accordance with the operation when starting the transfer operation with the refill mounted on the transfer tool body. It is characterized by doing.

  With such a configuration, the release mechanism is activated only after receiving the operation for starting the transfer operation, and the supply reel and the take-up reel can rotate. When not in use, the idle rotation prevention mechanism always provides the supply reel and the winding reel. By preventing the rotation of the take-up reel, it is possible to prevent idling of the supply reel and the take-up reel during transportation and the like without requiring the trouble of attaching and detaching the detent member.

  As an example of a configuration for operating the release mechanism in response to an operation when starting a transfer operation, the refill includes a storage position where the transfer head is immersed in the transfer tool body, and a use position where the transfer head is exposed to the outside. And the release mechanism uses the movement of the refill frame from the storage position to the use position to release the rotation prevention state by the idling prevention mechanism.

  As another example of the configuration for operating the release mechanism along with the operation when starting the transfer operation, the release mechanism uses the movement of the refill relative to the transfer tool body when the transfer head receives the transfer pressure. The thing which cancels the rotation prevention state by the said idling prevention mechanism is mentioned.

  As still another example of the configuration for operating the release mechanism in accordance with the operation at the start of the transfer operation, the transfer tool body includes a closed position for covering the transfer head and an open position for exposing the transfer head to the outside. And the release mechanism releases the rotation prevention state by the idling prevention mechanism using the movement of the cap from the closed position to the open position. .

  In addition, as an example of an aspect for enabling such a transfer tool to be used stably, a selection holding mechanism that selectively holds the refill in one of a storage position and a use position is further provided. Things. In such a case, by holding the refill in the storage position by the selective holding mechanism, it is possible to suppress the occurrence of problems such as the transfer head being exposed to the outside when not in use.

  As an example of a specific mode for realizing such a release mechanism with a simple configuration, the idling prevention mechanism is a latch that is elastically supported so that a fulcrum provided in a refill and set at an intermediate portion can be rotated and moved. The engaging portion provided at one end of the arm is engaged with the engaged portion provided on the supply reel or the take-up reel, and the release mechanism has a protrusion formed on the other end of the locking arm. An example is one in which the engaging portion is separated from the engaged portion by rotating the locking arm about the fulcrum by being pressed by a protrusion formed on the case.

  In particular, as a configuration for ensuring both the length and the mounting strength of such an arm, the locking arm includes an arm main body having the engaging portion at one end and the protrusion at the other end, and the arm. Examples include a shaft portion extending perpendicularly to the longitudinal direction of the arm body from a fulcrum set at the intermediate portion of the body, and an elastic support portion extending from the shaft portion along the longitudinal direction of the arm body.

  According to the configuration of the transfer tool of the present invention, the release mechanism is activated only after receiving an operation at the start of the transfer operation, so that the supply reel and the take-up reel can be rotated. By preventing the rotation of the feeding reel and the take-up reel, it is possible to prevent idling of the feeding reel and the take-up reel at the time of transportation and the like without requiring the trouble of attaching and detaching the rotation preventing member.

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. A cap guide protrusion 72 provided on both side edges of the facing surface, and a U-shaped protrusion in cross section provided at the rear portion of the support portion 61 of the cap 6, which is formed on the cap drive protrusion 71 and the cap guide protrusion 72. It is configured using a driven part 73 to be driven. The driven portion 73 includes a first wall 731 positioned on the transfer head 22 side of the cap driving projection 71 when the cap 6 is positioned at the closed position C, and a cap driving when the cap 6 is positioned at the open position O.

  When the slide frame 4 moves from the storage position S shown in FIG. 8 to an intermediate position between the storage position S and the use position U shown in FIG. 9, the cap drive protrusion 71 is the first wall body 731 of the driven portion 73. 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. Thereafter, the contact between the driven portion 73 and the cap guide protrusion 72 disappears, but the driven portion 73 comes into contact with the cap drive projection 71, and the cap drive projection 71 is connected to the second wall body 732 of the driven portion 73 and The cap 6 is driven by sequentially pressing the third wall body 733, and the cap 6 moves to the closing position C as the guide claw 611 of the cap 6 moves in the guide slit 311b.

The cap holding portion 74 is formed by engaging a holding projection 741 provided at one end in the longitudinal direction of the guide claw 611 of the cap 6 and a holding recess 742 provided on the back surface of the slide frame 4 and engaged with the holding projection 741. 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 46 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 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 supported on a feeding shaft 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 shaft 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.

  As described above, according to the configuration of the transfer tool T according to the present embodiment, the idling prevention mechanism 25 that prevents the rotation of at least one of the supply reel 21 and the take-up reel 23 when not in use, and the refill 2 are transferred. A release mechanism K for releasing the rotation prevention state by the idling prevention mechanism 25 is provided along with the operation when starting the transfer operation in the state of being mounted on the main body 1, so that it is not until receiving the operation when starting the transfer operation. The release mechanism K is actuated so that the supply reel 21 and the take-up reel 23 can rotate, and when not in use, the idling prevention mechanism 25 can always prevent the supply reel 21 and the take-up reel 23 from rotating. Therefore, it is possible to prevent idling of the supply reel 21 and the take-up reel 23 during transportation or the like without the need for attaching and detaching the rotation stopper.

  Particularly in the present embodiment, the refill 2 is supported so as to be movable between a storage position S where the transfer head 22 is immersed in the transfer tool body 1 and a use position U where the transfer head 22 is exposed to the outside. Since the release mechanism K uses the movement of the refill frame from the storage position S to the use position U to release the rotation prevention state by the idling prevention mechanism 25, the transfer operation is started. Accordingly, the release mechanism K can be reliably functioned.

  Furthermore, in this embodiment, since the refill 2 is further provided with a knock mechanism 5 that selectively holds the refill 2 in one of the storage position S and the use position U, the refill frame 24 is moved from the storage position S to the use position by the knock mechanism 5. The operation force of the operation to be moved to U can be converted into an action when the release mechanism K is functioned with the operation when starting the transfer operation.

  In addition, the anti-spinning mechanism 25 is provided with a latching claw 244x provided at one end of a latching arm 244 that is elastically supported so as to be able to rotate and support a fulcrum 244z that is provided in the refill 2 and is set at the intermediate portion, and the reel 21 The release mechanism K is pressed by a release release protrusion 321b formed on the outer case 3 with a protrusion 244y formed on the other end of the engagement arm 244. Thus, the locking claw 244x is separated from the locking teeth 21a by rotating the locking arm 244 around the fulcrum 244z, so that the release mechanism K is realized with a simple configuration. can do.

  The locking arm 244 includes an arm main body 244a having the locking claw 244x at one end and the projection 244y at the other end, and a longitudinal axis of the arm main body 244 from a fulcrum 244z set at an intermediate portion of the arm main body 244a. Since the shaft portion 244b extending perpendicularly to the direction and the elastic support portion 244c extending from the shaft portion 244b along the longitudinal direction of the arm body 244 are provided, the length of the arm body 244a is secured to the protrusion 244y. By providing an elastic support portion 244c extending from the shaft portion 244b along the longitudinal direction of the arm main body 244a while reliably releasing the rotation prevention state by the anti-spinning mechanism by applying a small action, the attachment strength is also increased. Can be secured.

  The present invention is not limited to the embodiment described above.

For example, as another embodiment, there is one that includes a release mechanism that releases the rotation prevention state by the idling prevention mechanism using the movement of the refill relative to the transfer tool body when the transfer head receives the transfer pressure. in this case,
As still another embodiment, the transfer tool body further includes a cap that is movable between a closed position that covers the transfer head and an open position that exposes the transfer head to the outside. There is also provided a release mechanism that releases the rotation prevention state by the idling prevention mechanism using the movement from the closed position to the open position.

  On the other hand, in the above-described embodiment, instead of the knock mechanism, there is provided a selection holding mechanism that selectively holds the refill not only at the storage position and the use position but also at a predetermined position set in the middle thereof. May be.

  In addition, an anti-spinning mechanism having another configuration may be employed, such as engaging the locking claws of the locking arm described above with the ratchet teeth of the take-up reel.

  In addition, various modifications may be made without departing from the spirit of the present invention.

  The present invention is such that a transfer tape provided with a transfer product is supplied from a supply reel during use and wound on a take-up reel, and prevents rotation of at least one of the supply reel or the take-up reel when not in use. It can be used for a transfer tool having an idling prevention mechanism.
