Description

Transfer tool

The present invention relates to a transfer tool formed by winding and holding a transfer tape.

In general, in a transfer tool in which a transfer tape is wound and held on a pay-out reel and a take-up reel, many of these reels whose gears are linked by a gear are fitted to the pay-out reel and a part of the pay-out reel. Thus, a clutch mechanism, which is also called a sliding mechanism for allowing a difference in the rotational speed, in other words, the amount of rotation per time, that is, a deviation, is provided between the revolving gear and the rotating gear ( For example, see Patent Document 1).

The transfer operation of such a transfer tool will be described. First, at the start of the transfer operation, rotation of the feeding reel is mainly performed, and the feeding gear attached to the feeding reel via the clutch mechanism and the winding gear meshing directly or indirectly with the feeding gear are rotated. As a result, the take-up reel that rotates integrally with the take-up gear is rotated.

Here, the ratio of the number of teeth of the take-out gear and the take-up gear is such that the amount of tape taken up by the take-up reel is always larger than the amount of tape fed out of the take-up reel when rotating integrally with the take-out gear. Is set. In other words, the take-up reel generates a pulling force that is larger than the size necessary for winding the transfer tape fed from the feed reel.

Furthermore, once the transfer operation of the tape is performed, the movement of the tape by the transfer operation and the operation of the take-up reel are mainly linked, so that the tape after transfer is wound around the take-up reel without slack. Therefore, the tape feeding amount of the feeding reel after the take-up gear reel is rotated becomes larger than the tape amount of the feeding reel when it is rotated together with the feeding gear.

That is, in the transfer tool, the transfer operation is performed while always maintaining a state where the rotation amount of the feeding gear and the rotation amount of the feeding reel are different, and the above-mentioned clutch mechanism is always operated to allow the difference in the rotation amount. Yes.

Unlike the above-described one, in the case where both reels are interlocked by a belt / pulley mechanism, the same operation as that of the clutch mechanism can be achieved by adopting a configuration that allows the deviation of the operation of the belt and the pulley. Realized.

JP 2003-54192 A

An example of the clutch mechanism is a clutch mechanism CL as shown in FIG. That is, for example, the first member CL1 that rotates integrally with a reel (not shown) on the winding side and has a cylindrical peripheral surface CL10 provided by integral molding of the resin, and the gear G and the first member CL1 rotate together. A member having a second member CL2 having a convex portion CL20 as a friction generating portion which is fitted to the first member CL1 and abuts against the peripheral surface CL10.

Such a clutch mechanism CL can easily set the desired frictional strength required for the transfer tool of each aspect by appropriately arranging the protrusions CL20. As an example, FIG. 2 shows a clutch mechanism CL in which four protrusions CL20 are provided at equal intervals of 90 ° along the circumferential surface.

Here, the inventors of the present application have found that when such a configuration is adopted, when the transfer tool is transferred with a constant force, a timing at which the feeding of the tape of the transfer tool is slightly delayed locally in the middle. Depending on the degree of stagnation of such tape feeding or winding, the transfer operation itself may stagnate, or a user who has transferred with increasing force according to the timing may be transferred after the timing such as an adhesive or a correction agent. It was discovered that there is a risk of incurring defects such as transferring an extra distance.

And as a result of investigating the cause of the stagnation of the tape delivery, the inventors of the present application have a cylindrical peripheral surface CL10 of the first member CL1 formed by integral molding of the resin, and the circumferential direction of the peripheral surface CL10. It has been found that this is caused by the arrangement of the convex portion CL20 which is a friction generating portion which is intermittently abutted on the surface.

The cause will be described in detail with reference to FIG. The figure schematically shows the peripheral surface CL10 of the first member CL1 and the arrangement of the convex portions CL20 that intermittently abut in the circumferential direction of the circumferential surface.

First, when the present inventors adopt a mold in which a true cylindrical space is accurately formed, the molded product is slightly flat but slightly flat in one direction for reasons such as how the resin flows in the mold. We focused on the oval shape. Then, when the second member CL2 having four convex portions CL20 at 90 °, for example, is fitted to the slightly elliptical circumferential surface CL10 as shown in FIG. 25, at a timing surrounded by a square in the drawing. I discovered that the above-mentioned delay in the feeding of the tape occurs.

Further, the same problem is not limited to the mode shown in FIGS. 24 and 25, but the mode shown in FIG. 26 in which eight convex portions CL20 are provided at equal intervals along the circumference at intervals of 22.5 °, or 60 °. Even in the case of adopting the embodiment shown in FIG. 27 in which six projections CL20 are provided at regular intervals along the circumference at intervals, the feeding of the tape is similar to the above-described embodiment having four projections CL20 at 90 °. I found out that the stagnation of.

The present invention focuses on the problems first discovered by the inventor of the present invention as described above, and an object thereof is to provide a transfer tool that can surely realize a smooth transfer operation without delay.

In the present invention, the following means are taken in order to achieve such an object. That is, the transfer tool according to the present invention is provided between a reel around which the transfer tape is wound and a gear that can rotate coaxially with the reel, and allows a difference in rotation amount between the reel and the gear. A transfer mechanism having a clutch mechanism for rotating first with either the reel or the gear and having a cylindrical peripheral surface provided by integral molding of resin And a second member having four or more friction generating portions that rotate integrally with the other and fit to the first member and abut against the peripheral surface, the friction generating portion When two sets of two friction generating portions adjacent to each other in the circumferential direction are arbitrarily selected, a vertical bisector connecting two adjacent friction generating portions belonging to one set, and the other Two adjacent frictions belonging to the set It is characterized in that the perpendicular bisector of a line connecting the parts are arranged all the friction generating portion to be formed differently.

In the transfer tool according to the present invention, when two sets of two friction generating portions adjacent to each other in the circumferential direction are arbitrarily selected, the two friction generating portions adjacent to the cylindrical shape are planar from the center of the cylinder. All the friction generating parts are positioned so as to be different from the virtual arrangement arranged symmetrically with respect to the viewpoint.

That is, the inventors of the present application have found that the friction generating portions as shown in FIGS. 24, 25 and 26 are common in satisfying the requirements shown in FIG. Describing based on the same figure, when two sets of two friction generating portions adjacent to each other in the circumferential direction among the convex portions CL20 as the plurality of friction generating portions are arbitrarily selected, two adjacent ones belonging to one set are selected. When the vertical bisector a1 of the line segment a connecting the convex portions CL20 and the vertical bisector b2 of the line segment b connecting the two adjacent convex portions CL20 belonging to the other set overlap. It has been discovered that the movement of the transfer tape occurs because the two adjacent convex portions CL20 sandwich the opposing short portion CL11 of the circumferential surface CL10 having a slightly flat elliptical shape. . Unlike the embodiment shown in the figure, when two adjacent convex portions CL20 come into contact with the circumferential surface CL10 from the outside, the long portions CL12 facing the circumferential surface CL having a slightly flat elliptical shape are opposed to each other. It is thought that the same situation will occur by sandwiching.

More specifically, when the adjacent distances of the two pairs of convex portions CL20 are equal, in other words, the arrangement of the convex portions CL20 that overlaps with the virtual arrangement d arranged symmetrically with respect to the plane viewpoint from the center c of the cylinder. In doing so, I found that such a stagnation clearly occurs.

That is, by adopting such a configuration, it is possible to realize a clutch mechanism that can operate smoothly with required friction in any rotary stage. By doing so, it is possible to provide a transfer tool that can surely realize a smooth transfer operation without delay.

Further, when the above configuration is applied, as a configuration for suitably obtaining the required friction as a clutch mechanism necessary for configuring the transfer tool, 30 ° along the circumferential direction of the peripheral surface of the first member. The friction generating part blocks are formed at three equal angles at intervals, and the friction generating part blocks are arranged at three equal angles at 120 ° intervals.

And in order to be able to adjust the friction strength more precisely, it is desirable that the second member further has a notch part in which the friction generating part block is notched in the circumferential direction. It is preferable to obtain the required frictional strength by appropriately adjusting the shape of the notch.

The transfer tool according to the present invention is provided between a reel for winding and holding the transfer tape and a gear that can rotate coaxially with the reel, and allows a difference in rotation amount between the reel and the gear. A transfer mechanism having a clutch mechanism for rotating first with either the reel or the gear and having a cylindrical peripheral surface provided by integral molding of resin And a second member having three friction generating portions that rotate integrally with the other member, engage with the first member, and come into contact with the peripheral surface. .

Even in such a case, it is possible to effectively avoid the arrangement of the friction generating portion as shown in FIG.

Then, while avoiding the arrangement of the friction generating portion as shown in FIG. 28, the required friction as the clutch mechanism can be obtained, and the transfer according to the present invention that can ensure a smoother operation as a component having an excellent weight balance. The tool is provided between a reel that winds and holds the transfer tape and a gear that can rotate coaxially with the reel, and a clutch mechanism that allows a difference in rotation amount between the reel and the gear. A transfer tool provided, which rotates integrally with either the reel or the gear, and has a first member having a cylindrical peripheral surface provided by integral molding of resin, and integrally with the other And a second member having a plurality of friction generating portions that abut on the circumferential surface, and the plurality of friction generating portions are provided intermittently at equal angular intervals along the circumferential direction. Characterized by Than is.

As a configuration for easily obtaining the above effect with a simple configuration, it is desirable to provide three friction generating portions at intervals of 120 °.

Here, as a clutch mechanism that can be applied to the transfer tool, it may be provided on the supply reel side for feeding out the transfer tape or on the take-up reel side for taking up the transfer tape after transfer. In view of easy application to a transfer tool having a configuration, the reel is a supply reel that rotates as the transfer tape is moved by the transfer operation, and the gear rotates as the supply reel rotates. It is desirable that the feeding gear and the clutch mechanism be provided between the feeding reel and the feeding gear, that is, the clutch mechanism is provided on the feeding reel side.

And since many of the existing transfer tools apply a mode in which the gear and the reel can be separated, such as a refill exchange type, the transfer tool of the present invention uses the second member as a gear, It is preferable that the first member having a circumferential surface is a support shaft member that supports the reel.

Of course, it is preferable to obtain the required frictional strength more precisely by further providing the second member with a notch in which the friction generating part is notched in the circumferential direction.

And, in the clutch mechanism according to the present invention, even if the circumferential surface of the first member is an inward circumferential surface, and the friction generating portion is in contact with the circumferential surface from the inside, Even if the circumferential surface of the first member is an outward circumferential surface, and the friction generating portion is in contact with the circumferential surface from the outside, the above-described effects are suitably achieved. .

In addition, the present invention can be suitably applied to a transfer tool that is generally used, that is, a transfer tool that transfers a correction agent or a transfer tool that transfers an adhesive. Smoother if applied to a transfer tool that can transfer a pressure sensitive adhesive that requires greater force for operation, i.e., a reel that can wind and hold a transfer tape holding the adhesive. It is possible to provide a transfer tool capable of performing a transfer operation.

According to the present invention, it is possible to realize a clutch mechanism that can operate smoothly with required friction in any rotary stage. By doing so, it is possible to provide a transfer tool that can surely realize a smooth transfer operation without delay.

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 protrusion 244y hits the locking release protrusion 321b, the arm main body 244a rotates around the fulcrum 244z, and the locking claw 244x is separated from the locking tooth 21a. 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 in 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.

Furthermore, a release mechanism is provided between the refill 2 and the second case member 32 for releasing the rotation prevention state of the refill 2 by the idling prevention mechanism 25. The release mechanism 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. This release mechanism 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. The locking claw 244x at the distal end of the locking arm 244 is separated from the locking tooth 21a 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 locking claw 244x at the tip of the locking arm 244 is engaged with the locking teeth 21a of the feeding reel 21. As a result, the rotation of the feeding reel 21 is restricted again.

Hereinafter, the sliding mechanism 8 formed by the feeding gear 43 (CL2) corresponding to the second member of the present invention and the clutch 44 (CL1) corresponding to the first member, that is, the clutch mechanism CL will be described with reference to FIGS. This will be described in detail with reference to FIG. 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 (CL1) that rotates integrally with the feeding reel 21, and further transmitted from the clutch 44 (CL1) to the feeding gear 43 (CL2). The feeding gear 43 (CL 2), 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 product 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 increase ratio (or speed reduction ratio) between the feeding gear 43 (CL2) 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. To do.

In order to prevent such an increase in tension, the clutch 44 (CL1) is slid with friction with respect to the feeding gear 43 (CL2), thereby causing a difference in the rotational speed between the two, and feeding the tape on the feeding reel 21. A clutch mechanism CL that matches the speed and the tape winding speed of the take-up reel 23 is provided. The degree of slippage in the clutch mechanism CL, in other words, the rotational speed difference between the clutch 44 (CL1) and the feeding gear 43 (CL2) is 0 or small when the transfer tape is unused, and the transfer tape is used. It grows as the remaining amount decreases. As shown in FIGS. 13 to 15, the feeding gear 43 (CL2) has an outer tooth portion 431 formed with outer teeth meshing with the first intermediate gear 45 on the outer periphery, and extends in the axial direction in the central portion. It has a boss shaft part 432 and an annular groove 433 that opens in the axial direction separating the external tooth part 431 and the boss shaft part 432. The boss shaft portion 432 has a substantially thick cylindrical shape, but the front end side is notched at a plurality of locations, and is not continuous in the circumferential direction by the notches 432b, that is, the notch portions CL21 according to the present invention. . In addition, the outer peripheral surface has a plurality of convex portions 432 (CL20) intermittently along the circumferential direction. Each convex portion 432a (CL20) bulges slightly 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 each faces each convex part 432a (CL20) along the radial direction. Here, the convex portion 432a corresponds to the friction generating portion CL20 according to the present invention.

The clutch 44 (CL1) has 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 (CL1) is assembled to the feeding gear 43 (CL2) by inserting the boss shaft portion 432 into the fitting portion 442 and simultaneously inserting the flange 442a of the fitting portion 442 into the annular groove 433. As shown in FIG. 16, in the state where the clutch 44 (CL1) is assembled to the feeding gear 43 (CL2), the convex portion 432a (CL20) of the boss shaft portion 432 is formed on the inner peripheral surface of the fitting portion 442, that is, the peripheral surface CL10. Closely. 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. Furthermore, 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. The engagement between the outward projecting piece 442b and the inward projecting piece 433a prevents the boss shaft 432 from being pulled out from the fitting portion 442, and the clutch 44 (CL1) is disengaged from the feeding gear 43 (CL2). A retaining structure to prevent this is constructed.

In this clutch mechanism CL, torque is transmitted by sliding friction between the inner peripheral surface CL10 of the fitting portion 442 of the clutch 44 (CL1) and the convex portion 432a (CL20) of the boss shaft portion 432 of the feeding gear 43 (CL2). The boss shaft portion 432 formed with the notch 432b, that is, the notch portion CL21, can be elastically deformed so that the diameter thereof is contracted, and the convex portion 432a (CL20) is inserted into the fitting portion 442 by repulsion of the elastic deformation. It is possible to generate an appropriate magnitude of friction torque by pressing against the circumferential surface CL10. 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.

These feeding gear 43 (CL2) and clutch 44 (CL1) are both supported on a feeding shaft 42 integrally formed with the slide frame 4. That is, as shown in FIG. 3, the feeding shaft 42 is inserted into the inner space of the boss shaft portion 432 and the base shaft portion 441 from the feeding gear 43 (CL2) side, whereby the feeding gear 43 (CL2) and the clutch 44 are inserted. (CL1) is rotatably supported by the slide frame 4. In addition, a portion excluding the base shaft portion 441 of the clutch 44 (CL 1) and the flange 442 a of the fitting portion 442 fits inside the feeding reel 21 in the bag where the refill 2 is attached to the slide frame 4. The rib 441a protruding from the base shaft portion 441 of the clutch 44 (CL1) is engaged with the unevenness of the inner periphery of the supply reel 21, and plays a role of synchronizing the rotation of the supply reel 21 and the rotation of the clutch 44 (CL1).

Here, in the transfer tool T according to the present embodiment, as shown in FIG. 13, based on the above-described configuration, the clutch 44 that is a support shaft member that supports the take-up reel is the first member CL <b> 1, and the feeding gear is used. 43 is a second member CL2 of the present invention, and a clutch mechanism CL that allows a difference in rotational speed between the feeding reel 21 and the feeding gear 43 that occurs during transfer by the first part CL1 and the second member CL2 is provided. It is composed.

FIG. 17 schematically shows the configuration of the clutch mechanism CL shown in FIGS. Since the clutch 44, that is, the first member CL1 is integrally formed of resin, the molded cylindrical shape is formed with a short portion CL11 and a long portion CL12 as shown in FIG. It has an elliptical shape. And the figure has shown the aspect which 1st member CL1 rotates relatively with respect to this feeding gear 43, ie, 2nd member CL2. Thus, each convex part CL20 which is a friction generating part is rotating relatively, varying the contact | abutting degree with respect to the surrounding surface CL10, ie, the internal peripheral surface CL10 of the fitting part 442. FIG. Further, in this embodiment, three notches 432, that is, the notches CL21 of the present invention, are arranged at equiangular intervals so as to be arranged in the middle of the adjacent convex portions CL20.

However, in the present embodiment, there are provided three convex portions CL20 that are friction generating portions that abut against the peripheral surface. Specifically, the odd three convex portions CL20 are equally provided at equal angular intervals of 120 °. By doing so, as shown in FIG. 28, as shown in FIG. 28, the first member CL1 and the second member CL2 are rotated at any angle when they are relatively rotated. It is an aspect in which two sets of two adjacent convex portions CL20 cannot be selected. That is, in this case, tentatively, the perpendicular bisector a1 of the line segment a connecting two adjacent protrusions CL20 belonging to one set and the vertical line segment connecting two adjacent protrusions CL20 belonging to the other set. In order to form a bisector, the two convex portions CL20 must be selected in an overlapping manner. However, if so, the two bisectors are formed differently. And of course, since there are three convex portions CL20, the virtual arrangement d as shown in FIG. 28, that is, the two convex portions CL20 adjacent to the cylindrical shape are symmetrical with respect to the plane view from the center c of the cylinder. The arranged virtual arrangement d is not formed.

With the configuration as described above, the clutch mechanism CL shown in the present embodiment has the required friction in any rotation stage in which the first member CL1 and the second member CL2 rotate relatively. It can operate smoothly. By doing so, a smooth and accurate transfer operation can be reliably realized without any delay.

In this embodiment, the second member CL2 further includes a notch CL21 in which a gap between the protrusions CL20 as a friction generating part is notched in the circumferential direction so that the friction strength can be adjusted more precisely. Therefore, the second member CL2 can be appropriately elastically deformed at the position of the notch CL21, and the required frictional strength of the clutch mechanism CL is realized.

Further, in the present embodiment, the clutch mechanism CL is provided on the feeding reel 21 side, so that the above effect can be easily obtained by the slight improvement in the shape from the other existing transfer tool T.

The transfer tool T according to the present embodiment transfers the adhesive. That is, in general, a smooth transfer operation by the clutch mechanism CL is realized even in a case where an adhesive that desires a larger acting force than that of a correction agent is transferred.

<Modification>
In the following, each modification of the present embodiment will be described, but the same reference numerals are given to the same components as those in the above-described embodiment, and detailed description thereof is omitted.

Further, the arrangement of the convex portions CL20 that are the friction generating portions in the clutch mechanism according to the present invention is not limited to those provided evenly at three equal angular intervals as in the above-described embodiment, and as shown in FIG. The five convex portions CL20 may be evenly arranged at equal angular intervals. Of course, as shown in FIG. 19, nine convex portions CL20 may be evenly arranged at equal angular intervals of 40 °.

Even in such a case, as shown in FIG. 28 described above, it belongs to the perpendicular bisector a1 of the line segment a connecting two adjacent convex portions CL20 belonging to one set and the other set. All the convex portions CL20 are arranged such that the vertical bisector b1 of the line segment b connecting two adjacent convex portions CL20 is different. Of course, the virtual arrangement d as shown in FIG. 28, that is, the virtual arrangement d in which the two convex portions CL20 adjacent to the cylindrical shape are arranged symmetrically from the center c of the cylinder is not formed.

In addition, as shown in FIG. 20, the friction generating portion block CL22 is formed by arranging the convex portions CL20 at three equal angles at intervals of 30 ° along the circumferential direction of the peripheral surface CL10 of the first member CL1. The friction generating unit blocks CL22 may be arranged in three sets at equal intervals at intervals of 120 °.

Even in such a case, similarly to the above, as shown in FIG. 28, the vertical bisector a1 of the line segment a connecting two adjacent convex portions CL20 belonging to one set and the other All the convex portions CL20 are arranged such that the vertical bisector b1 of the line segment b connecting two adjacent convex portions CL20 belonging to the set is different. Of course, the virtual arrangement as shown in FIG. 28, ie, the virtual arrangement d in which the two convex portions CL20 adjacent to the cylindrical shape are arranged symmetrically from the center c of the cylinder is not formed.

Further, in the case of the embodiment shown in the figure, the required friction can be obtained by providing a notch portion CL21 in which the space between the friction generating portion blocks CL22 is notched in the circumferential direction.

Further, for example, the convex portion 432a (CL20) is not made small in the boss shaft portion 432 as shown in FIG. 14 and the like, and as shown in FIG. It can also be formed into a shape expanded along the circumferential direction while being arranged at three equal angles. For example, the protrusion 432a (CL20) may be a protrusion extending in the circumferential direction. By setting it as such an aspect, the area which the convex part 432a (CL20) 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 portion 442 is pressed by the small convex portion 432a (CL20), and the possibility that the inner surface of the fitting portion 442 is locally deformed due to plastic deformation with aging is reduced.

Further, as shown in FIG. 23, the convex protrusion 432a (CL20) extending in the circumferential direction may be inclined so as to transition along the axial direction. In other words, when slipping occurs and the support shaft member 44 rotates relative to the feeding gear 43, the contact location in contact with the convex portion 432a (CL20) on the inner peripheral surface of the fitting portion 442 is displaced in the axial direction. Will be. Therefore, the plastic deformation or wear of the inner peripheral surface of the fitting portion 442 is further suppressed, the life of the clutch mechanism CL is extended, and it can be used for a longer period of time.

Even in such a modified embodiment, when the first member CL1 and the second member CL2 are rotated at any angle during the transfer, as shown in FIG. This is an aspect in which two sets of two adjacent convex portions CL20 cannot be selected.

Although the embodiment of the present invention has been described above, the specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

First, in the above-described embodiment and each modification, the aspect in which the circumferential surface is an inward circumferential surface is disclosed, but of course, the circumferential surface of the first member is an outward circumferential surface, and the friction Even when the generating portion is in contact with the circumferential surface from the outside, the same effects as those of the above-described embodiment and the modified example are obtained. In this case, when two sets of adjacent friction generating portions are arbitrarily selected, any friction generating portion is selected. ”The configuration in which the four friction generating portions do not sandwich the long portion of the elliptical circumferential surface and Therefore, the same effect as described above is obtained.

In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.

For example, although the refill exchange type transfer tool is disclosed in the above embodiment, the present invention may of course be applied to a single use type transfer tool. Further, the present invention is not limited to a transfer tool that transfers an adhesive, and can be widely applied to any transfer tool that transfers a transfer material applied to a transfer tape, such as a transfer tool that transfers a correction agent. can do. In addition, the specific form of the other internal structure of the transfer tool and the outer shape of the transfer tool is not limited to that of the above embodiment, and various forms including the existing ones can be applied.

The present invention can be used as a transfer tool for transferring a transfer material such as an adhesive, a correction tape, and a pigment onto a paper surface or other transfer target surface.
