Description

Technical Field

[0001] The present invention relates to a coating film transfer tool.

Background Art

[0002] A coating film transfer tool generally transfers a coating film applied to a transfer tape wound around a transfer head protruding from a case body to a surface to be transferred by a pressing portion of the transfer head. Here, when the portion of the transfer tape held by the head is exposed from the case body, the coating film may be damaged or erroneously transferred to other locations when not in use. Therefore, a coating film transfer tool with a head cover for protecting the portion of the transfer tape held by the transfer head has been developed. Furthermore, from the viewpoints of being less likely to get in the way during use and less likely to be lost, a coating film transfer tool equipped with a slide-type head cover has been developed (see Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the case of moving the tip of the head from the head exposure position where the tip of the head is exposed to the head storage position where the tip of the head is stored and in the case of moving from the head storage position to the head exposure position, the conventional slide-type head cover requires the user to slide the head cover, resulting in poor operability. In addition, since the head cover is only held in the head storage position or the head exposure position by engagement with a protrusion or the like provided on the case, there is a possibility that the locking may be disengaged or rattling may occur with a slight force.

[0005] Accordingly, an object of the present invention is to provide a coating film transfer tool including a head cover having good operability, capable of surely locking, and free from rattling.

Means for Solving the Problems

[0006] To solve the above problems, the present invention provides a coating film transfer tool including a case body provided with an opening at the front side, a transfer head protruding from the opening, a supply mechanism disposed inside the case body for supplying a transfer tape, a winding mechanism disposed inside the case body for winding up the transfer tape supplied from the supply mechanism and reversed at the tip of the transfer head, a head cover attached to the case body and capable of sliding back and forth between a head storage position covering the lower side of the transfer head and a head exposure position exposing the lower side of the transfer head, and a biasing member for biasing the head cover toward the head exposure position side.

[0007] The head cover may include a locking portion that locks to the transfer head at the head storage position.

[0008] The locking portion may have a locking surface extending rearward in the sliding direction of the head cover.

[0009] The locking surface may be a flat surface or a curved surface.

[0010] The head cover has a pair of contact portions spaced apart in a direction orthogonal to the sliding direction and protruding toward the case body side, and the interval between the pair of contact portions is wider than the width of the transfer tape. The contact portions contact the lower surface of the transfer head and move downward during the sliding movement from the head exposure position to the head storage position, and the contact with the lower surface of the transfer head is released and the downward movement is released at the head storage position.

[0011] The head cover has a pair of protruding portions that are spaced apart in a direction orthogonal to the sliding direction and protrude toward the case body side, and the case body may have a notch portion for accommodating the protruding portions when the head cover is in the head exposure position.

[0012] The head cover has flexibility, and the case body may have a space portion that allows the head cover to bend inward in the case body at the central portion of the head cover when the head cover is in the head storage position.

Advantages of the Invention

[0013] According to the present invention, it is possible to provide a coating film transfer tool including a head cover that has good operability, can be reliably locked, and does not generate rattling.

[0015] (First Embodiment) Hereinafter, the coating film transfer tool 1 of the first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the coating film transfer tool 1 of the first embodiment. Hereinafter, the left - right, front - rear, and up - down directions appropriately shown in the drawings will also be described as the left - right, front - rear, and up - down directions in the specification. Note that FIG. 1 shows a state where the later - described left case member 20L and the pressing ring 42 are removed so that the inside can be seen. FIG. 2 is an exploded perspective view of the coating film transfer tool 1 seen obliquely from above and from the front side. FIG. 3 is an exploded perspective view of the coating film transfer tool 1 seen obliquely from below and from the rear side. FIG. 4 is a cross - sectional view of the coating film transfer tool 1 of the first embodiment cut along a plane extending in the front - rear, up - down directions on the front side. In the first embodiment, the coating film transfer tool 1 transfers correction tape, but it is not limited to this, and it may be tape adhesive or the like.

[0016] The coating film transfer tool 1 includes a case body 20 provided with an opening 20a on the front side, a supply mechanism 30 and a winding mechanism 40 for the transfer tape 34b disposed inside the case body 20, and a transfer head 50 protruding from the opening 20a. In FIGS. 2 to 4, only the portion of the transfer tape 34b wound around the supply reel 34 is shown, and the portion that is pulled out from the supply mechanism 30, wound around the transfer head 50, and wound around the take-up reel 41 is not shown.

[0017] The coating film transfer tool 1 of the first embodiment further includes a head cover 60 movable between a head storage position (non-use position) that covers the lower side of the transfer head 50 and a head exposure position (use position) that exposes the lower side of the transfer head 50, and a spring 70 that is a biasing member that biases the head cover 60 toward the head exposure position side.

[0018] (Case body 20) The case body 20 includes a left case member 20L and a right case member 20R. The left case member 20L and the right case member 20R are connected to each other to form an internal space of the case body 20, and the supply mechanism 30, the take-up mechanism 40, and the transfer tape 34b are held in the internal space.

[0019] FIG. 5 is a perspective view of the transfer head 50 of the coating film transfer tool 1 as viewed from below with the transfer head 50 removed, where (a) shows the state with the head cover 60 removed and (b) shows the state with the head cover 60 attached. Also, in both FIGS. 5(a) and 5(b), the transfer tape 34b is not attached.

[0020] (Right case member 20R) The right case member 20R has a right side surface portion 21R and a right outer peripheral wall portion 22R that surrounds the outer periphery of the right side surface portion 21R. On the inner surface of the right side surface portion 21R, a supply reel support shaft 23 and a take-up reel support shaft 24 are erected side by side in the front-rear direction. Around the supply reel support shaft 23 on the inner surface of the right side surface portion 21R, circular ratchet teeth 23a are formed around the supply reel support shaft 23. The surface of the ratchet teeth 23a facing the front side in the forward rotation direction r of the gear member 31, which will be described later, is substantially perpendicular to the side surface of the case body 20, and the surface facing the reverse side in the r direction is a slope whose height gradually decreases in the direction opposite to the r direction.

[0021] The right outer peripheral wall portion 22R covers the portion other than the front side on the outer periphery of the right side surface portion 21R. The portion where the front side right outer peripheral wall portion 22R is not provided forms the opening 20a when the right case member 20R and the left case member 20L are connected.

[0022] Also, the portion of the right outer peripheral wall portion 22R from the front side below is the right engaging wall portion 27R having a shorter length (width) extending to the left than other portions. When the right case member 20R and the left case member 20L are connected, the right engaging wall portion 27R forms a substantially rectangular space portion 25 (shown in FIG. 5(a) etc.) extending in the front-rear direction between the left engaging wall portion 27L described later. Furthermore, a movement restricting protrusion 27a protruding to the left is formed at the front end of the right engaging wall portion 27R.

[0023] Furthermore, at the end portion on the right engaging wall portion 27R side of the wide portion other than the right engaging wall portion 27R in the right outer peripheral wall portion 22R, a columnar spring hanging portion 26a (shown in FIGS. 1, 2, and 3) protruding to the left is provided.

[0024] On the inner front side of the right side surface portion 21R of the right case member 20R, a substantially rectangular head holding portion 28 is integrally formed. The head holding portion 28 protrudes from the opening 20a, and a tapered head insertion protrusion 28a is formed at the tip. Protrusion portions 28b are provided on the left and right side portions of the head holding portion 28, respectively. Also, a notch portion 29 (shown in FIG. 5) is provided at the lower front side of the right case member 20R.

[0025] (Left case member 20L) The left case member 20L has a left side surface portion 21L and a left outer peripheral wall portion 22L surrounding the outer periphery of the left side surface portion 21L.

[0026] The left outer peripheral wall portion 22L covers the portion other than the front side on the outer periphery of the left side surface portion 21L. As described above, the portion where the front side left outer peripheral wall portion 22L is not provided forms the opening 20a when the right case member 20R and the left case member 20L are connected.

[0027] Further, the portion of the lower front side of the left outer peripheral wall portion 22L is a left engaging wall portion 27L having a length (width) extending to the right that is shorter than other portions. As described above, when the right case member 20R and the left case member 20L are connected, the left engaging wall portion 27L forms a substantially rectangular space portion 25 (shown in FIG. 5(a) etc.) that extends back and forth between the right engaging wall portion 27R. And at the front end of the left engaging wall portion 27L, a movement restricting protrusion 27a extending to the right is formed.

[0028] Furthermore, a recess 26b is formed at the end of the left outer peripheral wall portion 22L on the side of the left engaging wall portion 27L in the wider portion other than the left engaging wall portion 27L. The recess 26b houses the spring hanging portion 26a of the right case member 20R when the right case member 20R and the left case member 20L are connected. Also, a notch portion 29 (shown in FIG. 5) is provided at the lower front side of the left case member 20L. Furthermore, at the lower part of the right case member 20R and the left case member 20L, a wall portion 25a protruding downward is formed so as to surround the space portion 25 and the rear region of the space portion 25. The wall portion 25a surrounds the outer periphery (three sides) of the head cover 60 that slides back and forth. Note that it is not limited to the wall portion 25a protruding downward from the right case member 20R and the left case member 20L as in the embodiment, and a wall portion surrounding the outer periphery of the head cover 60 may be formed by recessing the lower surface of the case member. By adopting such a structure, the possibility of the head cover 60 being accidentally pushed can be reduced.

[0029] (Supply mechanism 30) The supply mechanism 30 includes a gear member 31, a compression spring 32, a stopper member 33, and a supply reel 34 around which a transfer tape 34b is wound. Note that the supply mechanism 30 is not limited to this configuration, and for example, it may not include all of these components such as the gear member 31, the compression spring 32, and the stopper member 33.

[0030] (Gear member 31) The gear member 31 is provided with a cylindrical portion 31a at the center through which the supply reel support shaft 23 of the right case member 20R is inserted.

[0031] On the outer periphery of the cylindrical portion 31a, a gear ring 31b having gears formed on its outer periphery is disposed, and the space between the cylindrical portion 31a and the gear ring 31b is connected by three connecting portions 31c extending radially outward from the cylindrical portion 31a. The space between the cylindrical portion 31a and the gear ring 31b is divided into three equal parts in a fan shape by the connecting portions 31c, and in one of the fan-shaped regions, an arm 31d extends in an arc shape. The arm 31d has one of the connecting portions 31c as its base end and extends in an arc shape along the circumferential direction in the direction opposite to the r direction. The arm 31d extends from the connecting portion 31c serving as the base end to the front of the connecting portion 31c provided in the direction opposite to the r direction. At the tip of the arm 31d, a ratchet claw 31e (shown in FIG. 3) protruding to the right is provided.

[0032] (Stopping member 33) The stopping member 33 has a stopping main body 33a on the base end side and a stopping cylindrical portion 33b extending from the stopping main body 33a. The stopping cylindrical portion 33b is divided into two parts so as to be elastically deformable on the inner diameter side. At the tip of the stopping cylindrical portion 33b, a stopping convex portion 33c protruding to the outer diameter side is provided. On the outer periphery of the stopping main body 33a, four stopping protrusions 33d are provided at equal intervals.

[0033] (Supply reel 34) On the inner peripheral surface of the supply reel 34, a rib portion 34a for locking the stopping protrusion 33d is provided. By the locking of the stopping protrusion 33d to the rib portion 34a, the stopping member 33 rotates integrally with the supply reel 34.

[0034] The supply reel 34 around which the compression spring 32 and the transfer tape 34b are wound is sequentially externally fitted onto the cylindrical portion 31a of the gear member 31, and the retaining member 33 is inserted into the cylindrical portion 31a from the left side of the supply reel 34 in FIG. 2. Then, the retaining projection 33c of the retaining member 33 is engaged with the right end face of the cylindrical portion 31a to prevent it from coming off, and the supply mechanism 30 is integrated. The retaining member 33 inserted into the gear member 31 can rotate relative to the gear member 31 with a frictional force by the compression spring 32. The supply mechanism 30 is inserted into the supply reel support shaft 23 and is rotatably held with respect to the supply reel support shaft 23.

[0035] When the gear member 31 starts to rotate in the r direction, the ratchet pawl 31e moves along the inclined surface of the ratchet teeth 23a, and the arm 31d is elastically deformed to overcome the ratchet teeth 23a, so the gear member 31 can rotate in the r direction. When the gear member 31 rotates in the direction opposite to r, the ratchet pawl 31e bites into the ratchet teeth 23a, and the movement of the ratchet pawl 31e in the direction opposite to the r direction is restricted, so the rotation of the gear member 31 in the direction opposite to the r direction is restricted.

[0036] (Take-up mechanism 40) The take-up mechanism 40 includes a take-up reel 41 and a pressing ring 42. Note that the take-up mechanism 40 is not limited to this configuration, and for example, it may not include the pressing ring 42. The take-up reel 41 has a take-up cylindrical portion 41a, a flange portion 41b provided on the right side of the take-up cylindrical portion 41a, and a gear 41c (shown in FIG. 3) provided on the right surface of the flange portion 41b. The take-up cylindrical portion 41a is a double cylindrical portion. The gear 41c meshes with the gear on the outer periphery of the gear member 31. The pressing ring 42 has an insertion cylindrical portion 42a and a flange portion 42b provided on the left side of the insertion cylindrical portion 42a. The insertion cylindrical portion 42a is inserted between the double cylindrical portions of the take-up cylindrical portion 41a, and the used transfer tape 34b is wound around the take-up cylindrical portion 41a between the flange portion 41b and the flange portion 42b. Note that, although the driving method of the supply mechanism 30 and the winding mechanism 40 in the embodiment was gear coupling, it is not limited thereto, and a driving method using a rubber belt or the like may be used.

[0037] (Transfer head 50) The transfer head 50 is provided with a spatula-shaped pressing portion 51 having a substantially triangular cross section in the front-rear and up-down directions at the front end. The pressing portion 51 is a portion for transferring the coating film to the transfer object, and extends in the left-right direction. In the embodiment, the coating film is transferred by the spatula-shaped pressing portion 51, but it is not limited thereto, and the pressing portion may be in the shape of a roller that is held between a pair of tape guides 52 described later and is rotatable. A hole portion 53 (shown in FIG. 3) extending from the rear side to the front side in the longitudinal direction is provided at the center portion in the left-right direction on the rear end surface of the transfer head 50.

[0038] The transfer head 50 includes a pair of tape guides 52 on both the left and right sides. Long holes 54 extending in the up-down direction are formed on the rear side of the pair of tape guides 52. When the head insertion protrusion 28a is inserted into the hole portion 53 and the protrusion 28b provided on the side portion of the head holding portion 28 is engaged with the long hole 54, the transfer head 50 is held by the head holding portion 28 so as to be swingable within a predetermined range, and the transfer head 50 is connected so as not to come out of the head holding portion 28.

[0039] The pair of tape guides 52 includes a right tape guide 52R and a left tape guide 52L that are parallel to each other. The right tape guide 52R and the left tape guide 52L are each provided on the upper side. In addition, lower tape guides 52d described later are provided at the lower portions of the right tape guide 52R and the left tape guide 52L, respectively.

[0040] (Head cover 60) FIG. 6 is a perspective view of the head cover 60. FIG. 7 is an enlarged perspective view of the front side of the coating film transfer tool 1, in a state where the head cover 60 is in the maximum extension position described later and the transfer tape 34b is wound around the transfer head 50. The head cover 60 is an elongated plate member extending in the front-rear direction, made of a flexible and deformable material. The head cover 60 is substantially rectangular, but the width gradually widens from left to right at the front side. The portions other than the front side and the upper end side of the L-shaped slide portion 63 (described later) have a substantially constant width, which is less than or equal to the width of the space portion 25 formed between the right engaging wall portion 27R and the left engaging wall portion 27L in the case body 20. As shown in FIG. 5(b), on the front side of the lower surface of the head cover 60, there are provided uneven portions 68 that are pressed when the user moves the head cover 60 forward. Further, at the central portion of the lower surface of the head cover 60, there is provided a pressing portion 69 where the user presses with a finger when retracting the head cover 60 from the head storage position to the head exposure position.

[0041] The head cover 60 is provided with a groove portion 61 having a U-shaped cross section extending in the front-rear direction from the rear end to the central portion of the upper surface, and a spring hanging portion 62 is provided at the front end of the groove portion 61. On the left and right of the central portion in the front-rear direction of the head cover 60, there are provided two L-shaped slide portions 63 that stand upright with a predetermined length in the front-rear direction and a predetermined height upward. The upper ends of the L-shaped slide portions 63 protrude outward in the left-right direction. That is, the L-shaped slide portions 63 are substantially L-shaped when viewed from the front-rear direction in the left-right cross section.

[0042] As shown in FIG. 7, on the front upper surface of the head cover 60, in the left-right direction, there is provided a ridge portion 64 having a predetermined length extending in the front-rear direction. Further, on the left and right outer sides and the front side of the ridge portion 64 on the front upper surface of the head cover 60, there are formed locking portions 65 as a pair of protrusions protruding from the ridge portion 64. The space between the pair of locking portions 65 is connected to the left and right by an extending portion 67 having a constant height slightly lower than that of the locking portions 65. The locking portion 65 is located in front of the ridge portion 64, and has an inclined portion 65c that gradually rises from the extending portion 67 continuously toward the left and right outer sides, and a side portion 65b that continuously covers the front side of the ridge portion 64 at a constant height from the inclined portion 65c and extends to the left and right outer sides of the ridge portion 64.

[0043] The distance W2 between the left protruding strip 64 and the right protruding strip 64 is equal to or greater than the width W3 of the transfer tape 34b and narrower than the width W4 of the pressing portion 51 of the transfer head 50. The width W1 between the left end of the left protruding strip 64 and the right end of the right protruding strip 64 is substantially equal to the width W4 of the pressing portion 51 of the transfer head 50.

[0044] As shown in FIGS. 4 and 6, a V-shaped depression 67a that opens rearward when viewed in the cross-section of FIG. 4 is formed in the extending portion 67. Also, a V-shaped depression 65a is formed in the locking portion 65 on the front side of the protruding strip 64.

[0045] The depression 65a is provided continuously from the depression 67a at the lateral ends of the depression 67a, but the depression 67a is deeper than the depression 65a.

[0046] The locking portion 65 locks to the transfer head 50 at the storage position of the head cover 60 described later. And the surface extending obliquely rearward in the depression 65a of the locking portion 65 is a locking surface 65a1 into which the pressing portion 51 of the transfer head 50 is inserted and locked.

[0047] Note that the locking surface 65a1 is a flat surface extending obliquely rearward in the cross-section shown in FIG. 4, but is not limited thereto. FIG. 8 is a diagram showing a modified example of the locking surface 65a1. As shown in FIG. 8(a), the locking surface 65a1 may be a curved surface. Also, as shown in FIG. 8(b), the locking surface 65a1 may be U-shaped, rising substantially at a right angle to the upper surface of the head cover 60 and further extending rearward from its upper end.

[0048] The head cover 60 is attached to the portion of the lower surface of the case body 20 that includes the space portion 25. At this time, the portions protruding outward in the left-right direction at the upper ends of the L-shaped slide portions 63 of the head cover 60 are placed on the upper surfaces (inner surfaces of the case body) of the right engagement wall portion 27R and the left engagement wall portion 27L. Thereby, the head cover 60 is prevented from dropping downward from the case body 20, and further, the right engagement wall portion 27R and the left engagement wall portion 27L serve as rails and the L-shaped slide portion 63 can slide back and forth. At this time, when the front end of the L-shaped slide portion 63 abuts against the movement restriction protrusion 27a, further forward movement of the head cover 60 is restricted, and when the rear end of the L-shaped slide portion 63 abuts against the rear edge portion of the space portion 25, further rearward movement of the head cover 60 is restricted.

[0049] (Spring) The spring 70 is a tension coil spring and is stretched between a spring hanging portion 62 provided on the head cover 60 and a spring hanging portion 26a provided on the case body 20. The spring 70 extends within the groove portion 61 of the head cover 60.

[0050] FIG. 9 is a diagram for explaining the operation of the head cover 60 in the coating film transfer device 1. FIG. 9(a) shows a state where the head cover 60 is in the head exposure position, FIG. 9(b) shows a state where the head cover 60 is in the maximum extension position, and FIG. 9(c) shows a state where the head cover 60 is in the head storage position. The description of the transfer tape 34b is omitted in FIG. 9. Also, the above-mentioned FIG. 7 is a front-side enlarged perspective view of the coating film transfer device, and the head cover 60 shown in FIG. 9(b) is in the maximum extension position, and the transfer tape 34b is also shown.

[0051] (Head exposure position) FIG. 9(a) shows a state where the head cover 60 is in the head exposure position where the pressing portion 51 at the tip of the transfer head 50 is exposed by being retracted rearward. This state is a state where the coating film transfer device 1 can be used. When the transfer head 50 is pressed against the surface to be transferred and moved rearward, the transfer tape 34b is fed out, and at the same time, the coating film held on the transfer tape 34b is transferred onto the surface to be transferred. When the transfer tape 34b is fed out, the supply reel 34 rotates, so the gear member 31 also rotates. Then, the winding reel 41, which meshes with the gear member 31 and the gear 41c, also rotates. As a result, the transfer tape 34b after the coating film transfer is reversed at the tip of the transfer head 50 and wound around the winding reel 41.

[0052] At the head exposure position, the head cover 60 is biased rearward by the force of the spring 70. However, since the rear end of the L-shaped slide portion 63 is in contact with the rear edge of the space portion 25 of the case body 20, further movement of the head cover 60 toward the rear side is restricted. Therefore, the head cover 60 is held at the head exposure position without rattling. Also, since the head cover 60 is always biased rearward, the head cover 60 will not return to the head storage state unintentionally.

[0053] The locking portion 65 of the head cover 60 is in the same position as the case body 20 in the left-right direction, and also overlaps with the front end of the case body 20 in the front-rear direction at the head exposure position. In the first embodiment, notches 29 (shown in FIG. 5) are provided at the lower front sides of the right case member 20R and the left case member 20L. The locking portion 65 as the protruding portion of the head cover 60 is housed in this notch 29 at the head exposure position. The notch 29 has a shape adapted to the shape of the locking portion 65 of the head cover 60. Therefore, the head cover 60 can be compactly housed in the case body 20 at the head exposure position.

[0054] (Maximum extension position) FIG. 9(b) and FIG. 7 show a state where the user presses the uneven portion 68 on the front side of the lower surface of the head cover 60 and slides it forward against the force of the spring 70 to extend the head cover 60 forward to the maximum extent. At this time, due to the provision of the uneven portion 68, the user can surely move the head cover 60 without slipping. When the locking portion 65 of the head cover 60 moves slightly forward of the pressing portion 51 of the transfer head 50, the front wall of the L-shaped slide portion 63 collides with the movement restriction protrusions 27a provided at the front ends of the right engagement wall portion 27R and the left engagement wall portion 27L respectively, so that the head cover 60 is restricted from moving further forward.

[0055] Here, when the head cover 60 is slid from the position in Fig. 9(a) to the position in Fig. 9(b), the left and right ends of the lower surface of the transfer head 50 come into contact with the locking portions 65 (contact portions) of the head cover 60. The locking portions 65 (contact portions) are spaced apart in a direction orthogonal to the direction of the sliding movement, and a pair of them project toward the case body side. At this time, since the head cover 60 has flexibility, the front side of the L-shaped slide portion 63 elastically deforms upon contact, and the locking portions 65 (contact portions) move downward. When the head cover 60 is further slid forward from this state, the contact between the left and right ends of the lower surface of the transfer head 50 and the locking portions 65 (contact portions) of the head cover 60 is released, the elastic deformation of the head cover 60 returns to its original state, and the downward movement of the locking portions 65 (contact portions) is released.

[0056] Note that the head cover may be structured to move downward without elastic deformation. In this case, a spring that biases the head cover can be used to return the head cover that has moved downward to its original position.

[0057] The interval W6 between the pair of locking portions 65 (contact portions) that contact the lower surface of the transfer head 50 is wider than the width W3 of the transfer tape, and since the extending portion 67 is lower in height in the vertical direction than the locking portions 65 (contact portions), the transfer tape 34b is always spaced apart from the upper surface of the head cover 60 during sliding. Therefore, the possibility that the coating film of the transfer tape 34b is damaged or peeled off is reduced.

[0058] Also, in the first embodiment, V-shaped ridge portions 64 are provided on the left and right of the front upper surface of the head cover 60. The interval W2 between the left ridge portion 64 and the right ridge portion 64 is equal to or greater than the width W3 of the transfer tape 34b and narrower than the width W4 of the pressing portion 51 of the transfer head 50. Therefore, after the locking portion 65 (contact portion) of the head cover 60 exceeds the lower surface of the lower tape guide 52d and further exceeds the pressing portion 51 of the transfer head 50, the pressing portion 51 (transfer tape 34b) approaches the upper surface of the head cover 60, but both side portions outside the width W3 of the transfer tape 34b of the pressing portion 51 are disposed on the protrusion 64. Accordingly, the transfer tape 34b held by the transfer head 50 maintains a state of being separated from the upper surface of the head cover 60, and the possibility that the coating film of the transfer tape 34b is damaged or peeled off is reduced. Note that, instead of providing the protrusion 64, a recess may be provided in a portion of the head cover 60 through which the transfer tape 34b passes, so as to maintain the transfer tape 34b in a state of being separated from the upper surface of the head cover 60.

[0059] (Head storage position) FIG. 9(c) shows a state in which, after the user releases the hand from the state of FIG. 9(b), the head cover 60 is pulled by the spring 70, and the pressing portion 51 of the transfer head 50 is locked and stored in the recess 65a of the locking portion 65. At this time, the head cover 60 is in a state where it is hardly elastically deformed. Note that, in the first embodiment, the locked portion of the locking portion 65 is the pressing portion 51 of the transfer head 50.

[0060] In the present embodiment, as shown in FIG. 7, the distance W2 between the left protrusion 64 and the right protrusion 64 is equal to or greater than the width W3 of the transfer tape 34b and narrower than the width W4 of the pressing portion 51 of the transfer head 50, and the width W1 between the left end of the left protrusion 64 and the right end of the right protrusion 64 is substantially equal to the width W4 of the pressing portion 51 of the transfer head 50. Further, as shown in FIG. 4, in the locking portion 65, the recess 65a on the front side of the protrusion 64 is shallower than the recess 67a in the portion where the extending portion 67 is disposed. Thereby, at the storage position of the head cover 60, the protrusion 64 contacts and locks to a portion of the transfer head 50 where the transfer tape 34b is not disposed (the recess 65a-shaped portion on the front side of the protrusion 64 functions as the locking portion 65). Therefore, it is possible to prevent the portion of the transfer head 50 where the transfer tape 34b is disposed from contacting the extending portion 67. Moreover, by adopting such a structure, a large gap is not formed between the lower side of the transfer head 50 and the head cover 60, so that it is difficult for dust or the like to enter between the transfer head 50 and the head cover 60. In addition, the product can be made into a compact shape.

[0061] Also, since the head cover 60 is biased rearward by the spring 70, the pressing portion 51 of the transfer head 50 can be housed without play, and an unintentional detachment of the head cover 60 is prevented. In particular, it is preferable that the head cover 60 is provided with locking portions 65 that lock in such a manner that at least two points on the left and right sides of the transfer head 50 are in contact with each other at the locking positions in the head housing position.

[0062] In the first embodiment, the angle θ1 between the lower surface formed in the recesses 65a provided on the left and right sides of the head cover 60 and the locking surface 65a1 is an acute angle. In this case, since the head cover 60 is biased rearward by the spring 70, the locking surface 65a1 of the recess 65a comes into contact with the tip of the pressing portion 51 of the transfer head 50, and the lower surface of the recess 65a also comes into contact with the lower surface of the pressing portion 51 of the transfer head 50. The pressing portion 51 of the transfer head 50 is locked and housed in a state of being sandwiched by the recesses 65a. Therefore, the head cover 60 is in a state with less play.

[0063] In addition, the longer the length of the locking surface 65a1 in the rearward sliding direction (the length in which the tip portion of the transfer head 50 is housed in the recess 65a at the head housing position), the greater the force required for the user to resist the spring 70 when removing the head cover 60, making it more difficult for the head cover 60 to come off.

[0064] In the deformation example shown in Fig. 8(a), when the angle θ2 between the lower surface of the recess 65a and the tangent line of the locking surface 65a1, which is a curved surface starting from the intersection of the lower surfaces of the recess 65a, is an acute angle, it is preferable because the pressing portion 51 of the transfer head 50 can be locked and housed in a state of being sandwiched.

[0065] Also, in FIG. 8(b) which is a modified example, the vertical distance between the lower surface of the recess 65a and the rear end of the locking surface 65a1 is preferably set to a distance that allows the pressing portion 51 of the transfer head 50 to be clamped from above and below by the lower surface of the recess 65a and the locking surface 65a1 and then locked and stored.

[0066] And since the transfer tape 34b held by the transfer head 50 is in a state of being separated from the upper surface of the head cover 60, the possibility that the coating film of the transfer tape 34b is damaged or peeled off is reduced.

[0067] (When the head cover is removed) The case body 20 has a space portion 25 at a part of the attachment position of the head cover 60. The head cover 60 is flexible, and the central portion overlaps with the space portion 25 when in the head storage position and has a slightly narrower width than the width of the space portion 25 (excluding the L-shaped slide portion 63). And the front portion and the rear portion of the head cover 60 are located at positions that do not overlap with the space portion 25.

[0068] Note that the space portion 25 is a through hole in the embodiment, but is not limited thereto, and it suffices to have a space that allows the central portion of the head cover 60 to flex inwardly of the case body 20 when the head cover 60 is in the head storage position.

[0069] In this state, when the pressing portion 69 provided at the center of the head cover 60 is pressed toward the inside of the case body 20, the head cover 60 flexes, and the central portion enters the inside of the case body 20 more than the space portion 25. On the other hand, the locking portion 65 moves downward and away from the pressing portion 51. Thereby, the engagement between the tip of the transfer head 50 and the locking portion 65 is released. Then, the head cover 60 is pulled backward by the force of the spring 70, the head cover 60 moves from the head storage position to the head exposure position, and the pressing portion 51 of the transfer head 50 is exposed, resulting in the state of FIG. 9(a) where the coating film transfer device 1 can be used. In this way, by a one-touch operation of pressing the central portion of the head cover 60 toward the inside of the case body 20, the head cover 60 can be easily moved from the head storage position shown in Fig. 9(c) to the head exposure position shown in Fig. 9(a), and the operability is good.

[0070] In addition, without pressing the lower surface of the portion located in the space portion 25 of the head cover 60 upward, the user presses the tip of the head cover 60 downward to move the locking portion 65 provided on the front side downward, and the locking portion 65 can also be released from the pressing portion 51 of the transfer head 50. Even in this case, since the head cover 60 is pulled backward by the force of the spring 70, the head cover 60 can be easily moved from the head storage position shown in Fig. 9(c) to the head exposure position shown in Fig. 9(a), and the operability is good.

[0071] (Second Embodiment) Next, the coating film transfer tool 1 according to the second embodiment of the present invention will be described. The difference between the coating film transfer tool 1 according to the second embodiment and the coating film transfer tool 1 according to the first embodiment lies in the locking portion 65 of the head cover 60 and the shape of the tape guide 52 of the transfer head 50. Since the other shapes are the same as those in the first embodiment, the description thereof will be omitted. Fig. 10 is a perspective view of the head cover 60 according to the second embodiment. Fig. 11 is a diagram for explaining the operation of the head cover 60 in the coating film transfer tool 1 according to the second embodiment, where (a) shows a state where the head cover 60 is in the head exposure position, (b) shows a state where it is in the maximum extension position, and (c) shows a state where it is in the head storage position. The description of the transfer tape 34b is omitted in Fig. 11. The same parts as those in the first embodiment in the second embodiment are denoted by the same reference numerals. Fig. 12 is an enlarged perspective view of the front side of the coating film transfer tool 1 according to the second embodiment, where the head cover 60 is in the maximum extension position shown in Fig. 11(b), and the transfer tape 34b is also shown.

[0072] In the second embodiment, a locking protrusion 52a that locks with the locking portion 65 of the head cover 60 is provided on the front side of the lower tape guide 52d on the lower side of the tape guide 52. The locking protrusion 52a protrudes in a V shape toward the front side. In addition, a pair of protrusions 66 are formed on the outer sides in the left - right direction of the front upper surface of the head cover 60. The pair of protrusions 66 are arranged at intervals in a direction orthogonal to the sliding direction of the head cover 60 and are provided so as to protrude toward the case body 20 side. The ridge 64 provided on the front upper surface of the head cover 60 extends to the tip of the head cover 60 beyond the locking portion 65. A recess 65a that is recessed in a V - shape in the cross - section in the front - rear and up - down directions is formed in the locking portion 65. A locking surface 65a1 that extends obliquely rearward is provided in the recess 65a, and the tip of the locking protrusion 52a that protrudes forward is inserted therein, and the head cover 60 is locked to the transfer head 50.

[0073] (Head exposure position) FIG. 11(a) shows a state in which the head cover 60 is in the head exposure position where the pressing portion 51 at the tip of the transfer head 50 is exposed by being retracted rearward. At the head exposure position, as in the first embodiment, the head cover 60 is biased to the rear head exposure position by the force of the spring 70. However, since the rear end of the L - shaped slide portion 63 is in contact with the edge of the space portion 25 of the case body 20, further movement of the head cover 60 to the rear side is restricted. Therefore, the head cover 60 is held at the head exposure position without play. In addition, since the head cover 60 is always biased rearward even at the head exposure position, the head cover 60 will not return to the head storage state.

[0074] (Maximum extension position) FIG. 11(b) and FIG. 12 show a state in which the user slides the head cover 60 forward against the force of the spring 70 to extend the head cover 60 forward to the maximum extent. Also at the maximum extension position, as in the first embodiment, when the locking portion 65 of the head cover 60 moves forward beyond the pressing portion 51 of the transfer head 50, the front wall of the L - shaped slide portion 63 collides with the movement - restricting protrusions 27a provided at the front ends of the right engagement wall portion 27R and the left engagement wall portion 27L respectively. Therefore, the head cover 60 is restricted from moving further forward.

[0075] However, in the second embodiment, when the head cover 60 is slid from the position in Fig. 11(a) to the position in Fig. 11(b), the lower surface of the transfer head 50 slides on the ridge 64 provided rearward from the tip of the head cover 60 and abuts against the locking portion 65 (contact portion) provided on the ridge 64. The interval W2 between the pair of locking portions 65 (contact portions) is wider than the width W3 of the transfer tape. At this time, since the head cover 60 has flexibility, when the locking portion 65 abuts against the lower surface of the transfer head 50, the front side of the L-shaped slide portion 63 is elastically deformed and the locking portion 65 (contact portion) moves downward. When the head cover 60 is further slid forward from this state, the locking portion 65 (contact portion) gets over the lower surface of the locking protrusion 52a which is the lower surface of the transfer head 50, and thereby, the contact between the locking portion 65 (contact portion) and the lower surface of the transfer head 50 is released. At this time, the elastic deformation of the head cover 60 returns to the original state and the downward movement of the locking portion 65 (contact portion) is released.

[0076] Also in the second embodiment, since the locking portion 65 abuts against the lower surface of the transfer head 50 and the transfer tape 34b held by the transfer head 50 is in a state of being separated from the upper surface of the head cover 60, similar to the first embodiment, there is an effect that the possibility of the coating film of the transfer tape 34b being damaged or peeled off is reduced.

[0077] Moreover, even after the locking portion 65 (contact portion) of the head cover 60 gets over the lower surface of the locking protrusion 52a which is the lower surface of the transfer head 50, since both ends of the pressing portion 51 are placed on the ridge 64, the transfer tape 34b held by the transfer head 50 is in a state of being separated from the upper surface of the head cover 60. Therefore, the point that the possibility of the coating film of the transfer tape 34b being damaged or peeled off is reduced is the same.

[0078] (Head storage position) Figure 11(c) shows a state where, after the user releases their hand from the state of Figure 11(b), the head cover 60 is pulled by the spring 70, and the locking protrusion 52a of the transfer head 50 locks onto the locking surface 65a1 of the recess 65a of the locking portion 65 and is stored. At this time, the head cover 60 is in a state where it is hardly elastically deformed. In the first embodiment, the portion where the locking surface 65a1 of the head cover 60 locks with the transfer head 50 was the pressing portion 51 of the transfer head 50. However, in the second embodiment, the portion (the locked portion of the locking portion 65) that locks with the locking surface 65a1 of the head cover 60 is different in that it is the locking protrusion 52a. Also in the second embodiment, since the head cover 60 is biased rearward by the spring 70, the transfer head 50 can be stored without rattling, and unintentional detachment of the head cover 60 is prevented. In particular, in the second embodiment, the angle θ3 formed between the upper surface of the ridge portion 64 and the locking surface 65a1 in the recess 65a of the locking portion 65 is an acute angle, which is approximately the same angle as the protruding angle of the locking protrusion 52a toward the front side. As the head cover 60 is biased rearward by the spring 70, the locking protrusion 52a is locked so as to be sandwiched between the upper surface of the ridge portion 64 and the locking surface 65a1 of the recess 65a of the locking portion 65. Therefore, the head cover 60 becomes a state with less rattling. At this time, even in the head storage state where the tip of the transfer head 50 is stored, the transfer tape 34b held by the transfer head 50 is in a state separated from the upper surface of the head cover 60. Therefore, the possibility of the coating film of the transfer tape 34b being damaged or peeled off is reduced.

[0079] (When releasing the head cover) Also in the second embodiment, when the pressing portion 69 provided at the central portion of the head cover 60 is pressed toward the inside of the case body 20, the head cover bends, the central portion enters the inside of the case body 20 from the space portion 25, and the locking portion 65 moves downward and away from the case body 20. Thereby, the engagement between the locking protrusion 52a of the transfer head 50 and the locking portion 65 is released. Then, the head cover 60 is pulled rearward by the force of the spring 70, and the head cover 60 moves from the head storage position to the head exposure position, and the pressing portion 51 of the transfer head 50 is exposed, resulting in the state shown in Fig. 11(a) where the coating film transfer tool 1 can be used. In this way, by a one-touch operation of pressing the central portion of the head cover 60 toward the inside of the case body 20, it is possible to easily move the head cover 60 from the head storage position shown in Fig. 11(c) to the head exposure position shown in Fig. 11(a), and the operability is good.

[0080] In addition, in the first and second embodiments, the biasing member is separate, but it may be a resin spring or the like in which the biasing member is integrally attached to the head cover, the case, the transfer head, or the like. Also, the coating film transfer tool 1 of the first and second embodiments is a so-called vertically pulled type coating film transfer tool 1, and the case body 20 is composed of a right case member 20R and a left case member 20L connected to each other. And the head cover 60 is provided so as to straddle the right case member 20R and the left case member 20L on the lower side of the case body 20, but it is not limited to this. For example, it may be a so-called horizontally pulled type coating film transfer tool, in which the case body is composed of an upper case and a lower case connected to each other, and the head cover is provided only on the lower case of the case body.
