Description

  The present invention belongs to the technical field of a coating film transfer tool for press-transferring a character correction coating film, an adhesive coating film for adhesion, a decorative coating film, and the like to a transfer target, and in particular, a feeding core and a winding core. It belongs to the technical field of a belt-driven film transfer tool in which the core is rotated by a belt.

  Conventionally, a transfer tape in which a coating film is provided on a base tape is fed from a feeding portion, the transfer tape is pressed by a transfer pressing portion, the coating film is transferred to a transfer surface, and then the base tape is wound up. A transfer tool is used. In such a coating film transfer tool, the feeding core for feeding the transfer tape and the winding core for winding the substrate tape are rotated in conjunction with each other so that the winding length of the base tape is longer than the feeding length of the transfer tape. The transfer tape T is prevented from sagging by applying an appropriate tension to the transfer tape T. With a belt-driven film transfer tool that rotates the feeding core and take-up core in conjunction with the belt, the take-up core and feeding core are rotated in conjunction with the belt, and a slip generated between the belt and the take-up core applies to the transfer tape. The tension that is being released is released. The torque when the belt and the winding core slip is called “slip torque”. Also, when the transfer tape is not used and the feeding pan pan outer diameter of the feeding core is large, it is called “initial use”, and the feeding tape has been used to reduce the feeding pan cake outer diameter. The state is called “end of use”.

  The tension of the “initial use” transfer tape is smaller than that of the “end use”. If the transfer tape is moderately tensioned, the coating film cuts immediately after the transfer is good, but if the transfer tape is small and the transfer tape sags at the transfer head part, the coating film will not be cut well, Cannot transfer. Therefore, in the coating film transfer tool, it is necessary to design the slip torque so that the tension of the transfer tape does not become too small even in the “initial stage of use”.

  On the other hand, at the “end of use”, a large tension is applied to the transfer tape of the coating film transfer tool. If the tension of the transfer tape becomes too high, when transferring the coating film to the transfer surface, it is necessary to press the transfer head strongly against the transfer surface to perform the transfer operation, and transfer failure of the coating film is likely to occur. Therefore, in the coating film transfer tool, it is necessary to design the slip torque so that transfer tension does not occur due to excessive tension of the transfer tape at the “end of use”.

  As described above, the setting of the slip torque of the coating film transfer tool must satisfy the conflicting requirements in the “initial use” and “end use”, the good setting range is very small, and the setting is difficult. It was. In addition, when a long transfer tape is stored, the diameter of the pancake outer diameter on which the transfer tape is wound is greatly changed between “initial use” and “end use”. The tension change of the transfer tape increases. Therefore, it has been particularly difficult to provide a coating film transfer tool containing a long transfer tape.

  In order to solve such problems, Patent Document 1 and Patent Document 2 propose a coating film transfer tool that shortens the distance between the feeding core and the winding core by the pressing force applied to the transfer head. . Since the tension of the belt decreases when the distance between the axes of both cores is shortened, these coating film transfer tools alleviate the tension of the transfer tape by pressing the transfer head when transferring the coating film. The film can be transferred by a pressing operation lighter than the coating film transfer tool.

However, in the coating film transfer tool of Patent Document 1 and Patent Document 2, the feeding core or the winding core moves in order to shorten the distance between the axes of the feeding core and the winding core, so the following (a), ( There were problems as shown in (a) and (c).
(A) Since the tape route length from the feeding core where the transfer tape runs to the take-up core changes due to the movement of the core, the transfer tape may sag and cause running failure.
(A) The core may be tilted during movement, and the base tape may be distorted by the take-up core, resulting in poor running.
(C) Since the tension of the transfer tape is reduced by pressing the transfer head, if the transfer head is pressed too strongly, the tension of the transfer tape becomes too small and the transfer tape may run poorly. Further, when the transfer head is separated from the transfer surface, the tension of the transfer tape is not maintained in a small state, so that the tension of the transfer tape at the start of pressing of the transfer head increases as the feeding-side pancake outer diameter decreases. Accordingly, it is not sufficient in terms of reducing the change in tension of the transfer tape between the “initial stage of use” and the “end of use period” in the coating film transfer tool containing a long transfer tape.

  In Patent Document 3, a movable member that automatically adjusts the tension of the belt by deformation of the elastic member is provided between the feeding core and the take-up core, and the movable member moves according to the tension of the transfer tape. A coating film transfer tool that reduces the tension applied to the film is disclosed.

  However, even with the coating film transfer tool disclosed in Patent Document 3, each time the coating film is transferred, the movable member is moved by the tension of the transfer tape to reduce the tension applied to the belt. When separated from the transfer tape, the tension of the transfer tape may not be maintained in a small state. Therefore, even in the coating film transfer tool of Patent Document 3, as the outer diameter of the feeding pancake becomes smaller, the tension of the transfer tape at the start of pressing of the transfer head increases, and the coating film transfer tool containing a long transfer tape is stored. In terms of reducing the tension change of the transfer tape between the “initial use” and the “end use”, it was not sufficient.

Japanese Patent Laid-Open No. 2002-28395 JP 2009-285883 A JP 2011-56696 A

  The problem to be solved by the present invention is that the change in tension of the transfer tape between “initial use” and “end of use” is small, and the tension of the transfer tape is small from “initial use” to “end of use” and has good operability. Provide transfer tools.

  The coating film transfer tool according to the A1 aspect includes a feeding unit that feeds out a transfer tape provided with a coating film on a base tape, and a transfer pressing unit that presses the transfer tape and transfers the coating film to a transfer surface. And a winding part that winds up the base tape after the coating film transfer, and a belt that is wound between the feeding part and the winding part and rotates the feeding part and the winding part in an interlocking manner. Prepare. The feeding unit is movable in a direction to reduce the distance between the feeding unit and the winding unit, and the coating film transfer tool is such that the movable feeding unit has a distance between the feeding unit and the winding unit. And a reverse movement preventing mechanism for preventing movement in the direction of moving away.

  The coating film transfer tool according to the B1 aspect includes a feeding unit that feeds a transfer tape provided with a coating film on a base tape, a transfer pressing unit that presses the transfer tape and transfers the coating film to a transfer surface, A winding unit that winds up the base tape after film transfer, and a belt that is wound between the feeding unit and the winding unit and rotates the feeding unit and the winding unit in an interlocking manner; Reverse movement that is movable in a direction to reduce the distance between the feeding portion and the winding portion and that prevents the movable feeding portion from moving in a direction in which the distance between the feeding portion and the winding portion is increased. It is a coating film transfer tool characterized by having a prevention mechanism.

  The coating film transfer tool according to the second aspect B2 further includes an elastic member that urges the movable feeding portion in a direction in which the distance between the feeding portion and the winding portion is increased. A coating film transfer tool according to the A1 aspect.

  In the coating film transfer tool according to the B3 aspect, the rotation center X of the feeding unit, the rotation center Y of the winding unit, and the coating film transfer position Z of the transfer pressing unit are in the order of X, Y, and Z. The coating film transfer tool according to the B1, B2, or A1 viewpoint, which is arranged on a substantially straight line.

  The coating film transfer tool according to the B4th aspect is a transfer in which the feeding-side pancake outer diameter is reduced from the initial stage of using the transfer-side pancake having a larger feeding-side pancake outer diameter wound around the feeding core of the feeding portion. The tension acting on the transfer tape itself and the tension acting on the transfer tape, with the line segment connecting the rotation center X of the feeding portion and the rotation center Y of the take-up portion taken as the line segment XY throughout the end of tape use.

  In the coating film transfer tool of the present invention, since the change in tension of the transfer tape between “initial use” and “end use” is small, the transfer tape tension is small from the “initial use” to the “end use” and the operability is good.

It is a figure which shows the various states of the coating-film transfer tool A of 1st Embodiment of this invention. It is a graph which shows the transfer pressure change of the coating-film transfer tool A1 of Example 1 of this invention, the coating-film transfer tool A2 of Example 2, and the coating-film transfer tool B1 of the comparative example 1. FIG. It is a figure which shows the coating-film transfer tool C which is 2nd Embodiment of this invention. It is a figure which shows the angle which presses a transfer head to a to-be-transferred material at the time of transfer pressing force measurement.

  In FIG. 1, the coating-film transfer tool A of 1st Embodiment of this invention is shown. FIG. 1A is a front view with the cover 2 removed. FIG. 1B is a QQ cross-sectional view of FIG. 1A with the cover 2 attached. FIG.1 (c) is an enlarged view of the winding core 5 of Fig.1 (a). FIG. 1D is a view showing a state in which only the slider 7 and the transfer head 4 are mounted on the case 1 of the coating film transfer tool A. The slider 7 is located at the farthest position from the shaft 1E on which the winding core 5 is mounted. It shows the attached state. FIG. 1E is an RR cross-sectional view of FIG. FIG. 1 (f) is a diagram showing a state in which only the slider 7 and the transfer head 4 are mounted on the case 1 of the coating film transfer tool A, and the slider 7 is at a position closest to the shaft 1 </ b> E on which the winding core 5 is mounted. It shows the attached state. FIG.1 (g) is an enlarged view of the S part of FIG.1 (d).

  This coating film transfer tool A is movable in a direction in which the feeding portion of the transfer tape T approaches the winding portion of the base tape T1, and the feeding portion of the transfer tape T moves away from the winding portion of the base tape T1. This is different from a conventional coating film transfer tool in which a feeding portion and a winding portion are rotated by a belt in an interlocking manner in that it has a reverse movement preventing mechanism for preventing movement to a position.

  As shown in FIG. 1, the coating film transfer tool A is a casing comprising a case 1 and a cover 2, a feeding side in which a transfer tape T in which a coating film for a correction tape is applied to a base tape T 1 is wound around a feeding core 3. Transfer of pancake, transfer head 4 for transferring the coating film to a transfer surface such as paper, winding core 5 for winding the substrate tape T1 after coating film transfer, and rotation of the feeding core 3 are transmitted to the winding core 5. An O-ring 6 and a slider 7 are included. The slider 7 pivotally supports the feeding core 3 and can move in the direction of the winding core 5. The slider 7 is provided with a ratchet claw 7A as a mechanism for restricting the moving direction of the feeding core 3 to one direction. The ratchet claw 7A meshes with the reverse movement prevention claw 1A provided in the case 1 to prevent the slider 7 from moving in the direction away from the winding portion.

  However, the coating film transfer tool according to the present invention is not limited to this, and has a transfer tape feeding portion and a winding portion for winding the substrate tape after coating film transfer. The coating film is transferred from the transfer section, transferred from the transfer tape to the transfer surface by the transfer head, and the substrate tape after the transfer of the coating film is wound up by the winding section. be able to. In the coating film transfer tool of the present embodiment, the feeding unit and the winding unit are rotated in conjunction with a belt such as an O-ring, and the feeding unit can move in a direction that brings the distance between the feeding unit and the winding unit closer. And it has a reverse movement prevention mechanism which prevents the said movable feeding part from moving in the direction which distances the distance between a feeding part and a winding part.

  When the coating film transfer tool A is moved on the surface to be transferred while the transfer tape 4 is pressed against the surface to be transferred by the transfer head 4, the coating film is transferred from the transfer head 4 to the surface to be transferred and the transfer tape T is transferred. Is fed from the feeding core 3, the rotation of the feeding core 3 is transmitted to the winding core 5 by the O-ring 6, and the base tape T <b> 1 after the coating film transfer is wound on the winding core 5. At this time, the take-up core 5 is set so as to take up the longer base tape T1 than the transfer tape T fed out by the feed core 3, so that the O-ring 6 and the take-up core 5 are wound to eliminate the difference. The take-up core 5 slips. For this reason, tension acts on the transfer tape T and the base tape T1.

  In the coating film transfer tool A, the rotation center X of the feeding core 3, the rotation center Y of the winding core 5, and the coating film transfer position Z of the transfer head 4 are provided on a substantially straight line in the order of X, Y, and Z. ing. When the coating film transfer tool A is used and the transfer tape T is fed out from the feeding core 3, a pulling force in the direction of the transfer head 4 acts on the feeding core 3 due to the tension of the transfer tape T.

  In the coating film transfer tool A, a slider 7 that rotatably supports the feeding core 3 is movable toward the winding core 5. For this reason, when the slider 7 is pulled in the direction of the transfer head 4 due to the tension acting on the transfer tape T, the feeding core 3 moves in the direction of the take-up core 5. As a result, the distance between the axes of the winding core 5 and the feeding core 3 is shortened, and the tension of the O-ring 6 is decreased.

  Since the tension of the O-ring 6 is reduced, the slip torque between the winding core 5 and the O-ring 6 is reduced, and the tension of the transfer tape T is also reduced. As a result, the coating film can be transferred even when the pressing force that presses the transfer head 4 against the surface to be transferred is small.

  At two locations on both sides of the slider 7 in the sliding direction, ratchet claws 7A are provided on the elastically deformable beam portions 7B. On the other hand, a plurality of reverse movement preventing claws 1A are continuously provided on both side portions of the rail portion 1B to which the slider 7 of the case 1 is mounted. When the slider 7 is attached to the case 1, the ratchet claw 7A on both sides and the reverse movement prevention claw 1A are engaged with each other. As shown in FIG. 1 (g), the ratchet claw 7A and the reverse movement preventing claw 1A are shaped so that when the slider 7 moves away from the winding core 5, the ratchet claw 7A and the reverse movement preventing claw 1A Engage strongly and prevent the slider 7 from moving. On the other hand, when the slider 7 moves in the direction approaching the take-up core 5, the entire beam portion 7B is deformed while the slope of the claw claw 7A slides along the slope of the reverse movement prevention claw 1A, thereby the ratchet claw 7A. Can overcome the reverse movement prevention claw 1A. For this reason, the slider 7 can move on the rail portion 1 </ b> B in the direction of the winding core 5, but cannot move in the direction away from the winding core 5.

  Therefore, when the feeding core 3 moves in the direction of the winding core 5, the distance between the winding core 5 and the feeding core 3 is maintained in that state, and the tension of the transfer tape T is maintained in a reduced state. For this reason, even if the outer diameter of the feeding-side pancake around which the transfer tape T is wound is reduced, the coating film can be transferred to the transfer surface only by pressing the transfer head 4 with a light pressing force.

  The slider 7 is provided with an elastic portion 7C. The elastic portion 7 </ b> C is a resin spring provided integrally with the slider 7. When the slider 7 is attached to the rail portion 1B of the case 1, the elastic portion 7C is slightly elastically deformed, and the slider 7 is pressed away from the winding core 5 by the elastic force of the elastic portion 7C.

  The main purpose of providing the elastic portion 7C is to adjust the tension of the transfer tape T. The tension of the transfer tape T varies depending on the tension of the transfer tape T itself and the outer diameter of the feeding side pancake. When the feeding core 3 is moved together with the slider 7 by the tension of the transfer tape T, the tension of the O-ring 6 is decreased and the tension of the transfer tape T is decreased. On the other hand, when the outer diameter of the feeding-side pancake is reduced by feeding the transfer tape T, the tension of the transfer tape T is increased. The main problem of the present invention is to reduce the change in tension of the transfer tape between “initial use” and “end use”. Therefore, the ideal of the present invention is that the tension of the transfer tape T does not change by the balance between the effect of reducing the tension of the O-ring 6 by the tension of the transfer tape T and the effect of reducing the outer diameter of the feeding pancake. is there.

  In the coating film transfer tool A, the direction in which the tension of the transfer tape T acts and the direction in which the take-up core 5 is present as viewed from the feeding core 3 substantially coincide with each other. Easy to move. Therefore, if the elastic part 7C is not provided in the coating film transfer tool A, the effect of reducing the tension of the O-ring 6 due to the tension of the transfer tape T is greater than the effect of reducing the outer diameter of the feeding side pancake. Cheap. For this reason, in the coating film transfer tool A, the elastic portion 7C is provided in order to prevent the tension of the O-ring 6 from becoming too small due to the tension of the transfer tape T.

  Another purpose of providing the elastic portion 7C is to prevent the slider 7 from moving in the direction of the winding core 5 due to an impact. When the slider 7 moves in the direction of the take-up core 5 due to the impact applied to the coating film transfer tool, the tension of the transfer tape T becomes small even though the outer diameter of the feeding pancake is not changed. Therefore, the tension of the transfer tape T becomes too small, and there is a risk of running failure such as the transfer tape T sagging. When the elastic portion 7C is provided, the slider 7 is always pressed in a direction away from the winding core 5, so that the slider 7 moves toward the winding core 5 due to an impact applied to the coating film transfer tool. Can be prevented.

  In the coating film transfer tool A, the elastic portion 7C is a resin spring provided integrally with the slider 7, but the elastic portion may be a separate member. Examples of the elastic portion of the separate member include a metal coil spring and a leaf spring. When it is necessary to set the elastic force with high accuracy, it is preferable to use a coil spring.

  The case 1 is preferably provided with a stopper 1 </ b> C that restricts the movement of the slider 7 in the direction of the winding core 5. The stopper 1 </ b> C is provided in order to prevent the transfer tape T from running poorly due to the slider 7 moving too far in the direction of the winding core 5. The stopper 1 </ b> C prevents the slider 7 from moving to a position where the tension of the transfer tape T falls below the appropriate value at the “end of use”.

  Moreover, it is preferable to provide a reverse rotation prevention mechanism at the winding portion of the coating film transfer tool of the present invention so that the wound base tape T1 is not reversed and sagging. In the coating film transfer tool in which the feeding part and the winding part are interlocked by the belt (O-ring 6), when the coating film on the transfer tape T is transferred to the transfer surface via the transfer head 4, the feeding is performed. The transfer tape T is pulled out from the core 3 and the feeding core 3 rotates, and the rotation of the O-ring 6 wound between the feeding core 3 and the winding core 5 is directed from the feeding core 3 side to the winding core 5 side. Push out. For this reason, the O-ring 6 heading from the feeding core 3 side to the winding core 5 side swells outward and sags. On the other hand, the O-ring 6 heading from the opposite winding core 5 toward the feeding core 3 side rotates the winding core 5 while being pulled and stretched by the rotation of the feeding core 3. In this state, when the coating film transfer tool is separated from the surface to be transferred, the O-ring 6 tries to return to the original length by its own elastic force, so that the transfer tape T is pulled out of the feeding core 3 and the winding core 5. By rotating in the direction opposite to the direction, the transfer tape T is pulled back from the winding core 5 side to the feeding core 3 side. Therefore, the base tape T1 that has been transferred by the transfer head 4 is pulled back to the feeding core 3 side, and there is no coating film at the coating film transfer position of the transfer head 4. For this reason, even if it is going to transfer a coating film to the desired position with a coating film transfer tool next, since there is no coating film in a coating film transfer position, the problem that it cannot transfer arises. When the reverse rotation prevention mechanism is provided in the winding portion, the winding core 5 can be prevented from rotating in the reverse direction due to the elastic force of the O-ring 6, so that the transfer tape T can be prevented from being pulled back to the feeding core 3 side. When the coating film is transferred to the desired position with the coating film transfer tool, the problem that there is no coating film at the coating film transfer position can be solved.

  In the coating film transfer tool of the present invention, the reverse rotation prevention mechanism of the winding unit plays an even more important role in the following points. In the coating film transfer tool of the present invention, the tension of the transfer tape T is used to move the feeding core 3 to reduce the tension of the O-ring 6 so that the tension of the transfer tape T does not become too large. ing. When the transfer tape T is pulled back to the feeding core 3 side by the elastic force of the O-ring 6, the tension of the transfer tape T is instantaneously reduced, and the movement of the feeding core 3 due to the tension of the transfer tape T becomes unstable. If the movement of the feeding core 3 due to the tension of the transfer tape T becomes unstable, the tension of the transfer tape T becomes unstable, and the intended tension may not be achieved. Thus, in the coating film transfer tool of the present invention, the reverse rotation prevention mechanism of the winding part also plays a role of stabilizing the tension of the transfer tape T.

  As shown in FIG. 1, the reverse rotation prevention mechanism of the winding portion of the coating film transfer tool A is composed of a reverse rotation prevention claw 1 </ b> D provided in the case 1 and a deformation claw 5 </ b> A provided in the winding core 5. When the winding core 5 is attached to the case 1, the winding core 5 is rotatably held on a shaft 1 </ b> E provided on the case 1. When the winding core 5 is mounted on the shaft 1E, the reverse rotation prevention claw 1D is continuously provided over the entire circumference of the portion where the deformation claw 5A contacts. The deformation claw 5A is provided at the tip of an elastic piece 5F that can be elastic. When the winding core 5 is attached to the case 1, the reverse rotation prevention claw 1D meshes with the deformation claw 5A. As shown in FIG. 1, when the take-up core 5 rotates in the direction opposite to the direction in which the base tape T1 is wound, the reverse-prevention pawl 1D and the deformation pawl 5A are formed. Meshes strongly and prevents the winding core 5 from rotating. On the other hand, when the winding core 5 rotates in the direction of winding the base tape T1, the elastic piece 5F is deformed while the inclined surface of the deformed claw 5A slides along the inclined surface of the reverse rotation preventing claw 1D. The claw 5A can overcome the reverse rotation prevention claw 1D. Therefore, the winding core 5 can rotate in the direction of winding the base tape T1, but cannot rotate in the direction opposite to the direction of winding the base tape T1.

  In the coating film transfer tool A, the rotation center X of the feeding core 3, the rotation center Y of the take-up core 5, and the coating film transfer position Z of the transfer head 4 are provided on a substantially straight line in the order of X, Y, Z. It is arranged. When provided on a substantially straight line in the order of X, Y, and Z, the direction of the rotation center Y of the winding core 5 viewed from the rotation center X of the feeding core 3 and the direction in which the transfer tape T pulls the feeding core 3 due to tension are approximately. Further, the feeding-side pancake and the winding core 5 in which the transfer tape T is wound around the feeding core 3 can be efficiently stored without providing a useless space in the case 1. Therefore, when X, Y, and Z are provided on a substantially straight line in this order, the axial distance between the feeding core 3 and the take-up core 5 can be surely shortened by the tension of the transfer tape T, and the coating film can be transferred. The tool can be small and compact.

  The coating film transfer tool of the present invention does not necessarily need to arrange X, Y, and Z on a substantially straight line in this order. For example, by moving the feeding core 3 in the direction of the take-up core 5 with the tension of the transfer tape T, the coating film that can reduce the change in the tension of the transfer tape T between “initial use” and “end use”. In the transfer tool, X, Y, and Z can be arbitrarily arranged. For example, the coating film transfer tool of the present invention may arrange X, Y, and Z as in the coating film transfer tool C that is the second embodiment of the present invention shown in FIG. Moreover, you may make it provide in order of X, Z, Y.

  FIG. 3A shows the “initial stage of use” of the coating film transfer tool C. In FIG. 3A, the direction of the rotation center Y of the winding core 5 as viewed from the rotation center X of the feeding core 3 and the direction in which the tension of the transfer tape T pulls the feeding core 3 are the same. When the transfer tool C is used and the outer diameter of the feeding pancake is reduced, the direction of the rotation center Y of the winding core 5 as viewed from the rotation center X of the feeding core 3 and the tension of the transfer tape T pull the feeding core 3. The directions will not match. However, in the coating film transfer tool C, the line segment XY connecting the rotation center X of the feeding core 3 and the rotation center Y of the take-up core 5 and the transfer tape T even at the “end of use” shown in FIG. The angle formed by is small. In other words, at the “end of use” of the coating film transfer tool C, the angle formed by the tension acting on the transfer tape T itself and the component force parallel to the line segment XY of the tension acting on the transfer tape T (FIG. 3B). The middle corner W) is small. Therefore, the component force parallel to the line segment XY of the tension of the transfer tape T is not significantly different from the tension itself of the transfer tape T. Even with the component force parallel to the line segment XY, the feeding core 3 and the winding core The distance between the shafts 5 can be surely shortened.

  As the angle W increases, the component force parallel to the tension line segment XY of the transfer tape T decreases, making it difficult to shorten the distance between the feeding core 3 and the winding core 5. The angle W is preferably 45 degrees or less and more preferably 30 degrees or less from “initial use” to “end use”. If this angle exceeds 45 degrees, the component force parallel to the line segment XY of the tension of the transfer tape T acting on the feeding core 3 becomes too small, and the tension between the winding core 5 and the feeding core 3 is caused by the tension of the transfer tape T. The effect of reducing the tension of the transfer tape T by reducing the distance between the axis and the transfer tape T may be reduced, and the change in the tension of the transfer tape T from the “initial use” to the “end use” may not be reduced. .

  In the coating film transfer tool of the present invention, the O-ring, that is, the belt that can be moved to reduce the tension is limited to the feeding portion. The tension of the O-ring can also be reduced by moving the winding part. However, even if the winding part can be moved, the change in tension of the transfer tape from “initial use” to “end use”, which is the subject of the present invention, cannot be reduced. There is also a risk of causing poor running.

  In the coating film transfer tool, the transfer tape is pressed against the transfer surface by the transfer head to transfer the coating film, so the tension is divided between the transfer tape before transferring the coating film and the base tape after transferring the coating film. And different tensions are applied. The tension acting on the transfer tape is the value obtained by dividing the torque that rotates the feeding pancake by the radius of the feeding pancake, and the tension acting on the base tape after the coating film is transferred is that the belt and winding core slide. Is a value obtained by dividing the slip torque generated by the radius of the pancake of the base tape wound around the winding core. While the torque and slip torque for rotating the feeding side pancake hardly change between “initial use” and “end use”, the radius of the feeding pancake becomes smaller as the transfer tape is fed, The pancake of the base tape wound around the winding core becomes larger as the base tape is wound up. Therefore, the tension acting on the transfer tape gradually increases from the “initial stage of use” to the “end of use”, and the tension acting on the base tape after transferring the coating film changes from “initial stage of use” to “end of use”. As it becomes, it becomes gradually smaller.

  When the feeding portion, that is, the feeding core 3 can be moved, the feeding core 3 is moved by the tension of the transfer tape T, so that the tension of the transfer tape T is reduced by the tension of the transfer tape T itself. For this reason, the larger the tension of the transfer tape T, the greater the effect of reducing the tension of the transfer tape T. Therefore, if the feeding core 3 can be moved, it is possible to reduce a change in tension of the transfer tape T from “initial use” to “end use”. On the other hand, if the winding portion, that is, the winding core 5 is movable, the winding core 5 is moved by the tension of the base tape T1, so that the tension of the transfer tape T is reduced by the tension of the base tape T1. . However, as the tension of the transfer tape T increases as described above, the tension of the base tape T1 decreases. Therefore, even if the winding core 5 can be moved, the transfer tape T can be moved from the “initial use” to the “end use”. The change in tension until "" cannot be reduced. Further, since the tension of the base tape T1 is the largest in the “initial stage of use” where the tension of the transfer tape T is small, the tension of the base tape T1 in the “initial stage of use” where it is not necessary to reduce the tension of the transfer tape T. The effect of reducing the tension of the transfer tape T due to is maximized. Therefore, if the take-up core 5 is movable, the tension of the transfer tape T may be excessively reduced at the “initial stage of use”, and a running failure of the transfer tape T may occur.

  According to the coating film transfer tool according to the above-described embodiment, even when a long transfer tape is accommodated, the change in tension of the transfer tape between “initial use” and “end use” is small. The transfer tape has low tension and good operability. Further, even if the transfer head is separated from the transfer surface after the coating film is transferred, the tension of the transfer tape does not change. Therefore, the pressing force of the transfer head when the coating film transfer is resumed does not increase, and the operability is further improved.

  A transfer tape in which a coating film for a correction tape was applied over a length of 10.2 m on a PET film subjected to double-sided release treatment with a width of 6 mm was wound around the feeding core 3 in FIG. 1 to prepare a feeding side pancake. . A coating film transfer tool A1 in which the feeding side pancake was accommodated in the coating film transfer tool of FIG. 1 was prepared. As an initial setting of the coating film transfer tool A1, the ratchet claw 7A of the slider 7 was set to engage with the reverse movement prevention claw 1A located farthest from the winding core 5 of the case 1. The elastic portion 7C of the slider 7 has a spring constant of 0.1 N / mm, and when the slider 7 is set to the initial state, the elastic portion 7C biases the slider 7 in the opposite direction of the winding core 5 by 1.3N. To do.

  As Example 2, a coating film transfer tool A2 different from the coating film transfer tool A1 of Example 1 only in the elastic part 7C of the slider 7 was prepared. The elastic part 7C of the slider 7 of the coating film transfer tool A2 has a spring constant of 0.1 N / mm, and when set to the initial state, the elastic part 7C is 1.7 N in the direction opposite to the winding core 5. Energize.

  As Comparative Example 1, there is no slider, the feeding core is rotatably supported at the initial position, and the shaft supporting the feeding core 3 is fixed (non-movable) in the case. A coating film transfer tool B1 similar to the film transfer tool A1 was prepared.

  Using the coating film transfer tools of Examples 1 and 2 and Comparative Example 1, each transfer pressing force was evaluated by the following method. The transfer object (PPC paper) is placed on the pedestal of the electronic balance with a pedestal, and the transfer head of the coating film transfer tool is pressed against the transfer object (PPC paper) at the angle shown in FIG. The transfer pressing force (load value indicated by the electronic balance) was measured. In this measurement, the transfer speed of the coating film transfer tool was 2 cm / second. The measurement of the transfer pressing force started from an initial state in which a correction coating film having a length of 10.2 m was wound around the feeding side pancake, and was measured every time 1 m of the correction coating film was consumed.

  The evaluation results were as shown in the graphs shown in Table 1 and FIG. Compared with the coating film transfer tool of Comparative Example 1, the coating film transfer tool of Examples 1 and 2 had a small change in transfer pressing force and good operability over the entire length of the transfer tape.
