Description

The present invention relates to an exchangeable coating film transfer tool that presses and transfers a coating film to a transfer target.

When the conventional film transfer tape is used up and a new film transfer tape is refilled, the used feeding core and winding core as in Patent Document 1 are used together with the feeding drive shaft of the main body and winding. The transfer tape was refilled by removing it from the drive shaft and attaching a new feeding core and take-up core held on the support to both drive shafts of the main body. Further, as in Patent Document 2, an exchange cassette storing a supply reel and a take-up reel for feeding a coating film transfer tape is mounted on both drive shafts of the main body to refill the transfer tape.

However, in the conventional coating film transfer tool, when the coating film transfer tape is refilled, it is necessary to remove the support from both reels when the feeding reel and take-up reel held by the support are mounted on both drive shafts. is there. In that case, the removal of the support and the supply reel does not work well, the supply reel lifts from the drive shaft and rotates, and the winding of the transfer tape loosens and loosens, and the supply reel smoothly moves to the drive shaft. There is a problem that the transfer tape is detached from the reel by mistakenly removed without being mounted.
In addition, there is no anti-rotation mechanism on the delivery reel of the exchange cassette in which the delivery reel and take-up reel are stored, and the delivery reel rotates and transfers due to the impact of vibration or dropping when the exchange cassette is moved. There are also problems such as tape loosening.

In view of the above, the present invention can eliminate the looseness and detachment of the transfer tape, the rotation of the feeding reel is blocked until the replacement cassette is mounted on the main body, and the rotation blocking means is released when the replacement cassette is mounted. It is an object of the present invention to make it possible to use a coating film transfer tool.

The present invention includes a feeding reel that feeds a coating film transfer tape formed with a coating film on a substrate, a transfer head that presses and transfers the coating film to a transfer target, and a winding that winds the substrate after transfer. In a coating film transfer tool comprising an interlocking mechanism that interlocks the take-up reel and both reels, an exchange cassette provided with the feeding reel and the take-up reel provided with rotation prevention means can be attached to and detached from the main body provided with the interlocking mechanism. The above problem has been solved by the coating film transfer tool, wherein the rotation preventing means is released by attaching the replacement cassette to the main body.

According to the present invention, since the rotation of the feeding reel is blocked until the replacement cassette is mounted on the main body, and the rotation blocking means is released when the mounting of the replacement cassette is completed, the feeding reel rotates and transfers during mounting. The tape does not come loose or come off the reel. Therefore, there is an effect that the transfer tape can be refilled only by mounting the replacement cassette on the main body without worrying about the rotation of the feeding reel.

Embodiments of the present invention will be described with reference to the drawings.
1A and 1B are diagrams showing the internal structure of an exchange cassette. FIG. 1A is a view when the exchange cassette is not attached to the main body, and FIG. FIG. 2 is a diagram showing only the outer shape of the replacement cassette attached to the main body shown by a solid line, by a dashed line.
The coating film transfer tool 1 according to the present invention is such that an exchange cassette 3 (an exchange cassette in a state where FIG. 1A is turned over) is detachably attached to a main body 2. The state is displayed in FIG.

The exchange cassette 3 includes a supply reel 4 for feeding out a coating film transfer tape having a coating film formed on a substrate, a transfer head 6 that presses and transfers the coating film to a transfer target, and a substrate after transfer. Is wound between the upper wall plate and the lower wall plate of the exchange cassette 3, and both reels 4, 5 are rotatably supported between the upper and lower wall plates, and the transfer head 6. Is fixed to the inner surface of the lower wall plate with the tip of the transfer head 6 protruding out of the replacement cassette 3 at a position where a part of the side wall covering the periphery of the replacement cassette 3 is opened. An elastic claw member 11 provided on the inner surface of the lower wall plate of the replacement cassette 3 meshes with the ratchet teeth 10 provided on the outer periphery of the supply reel 4 and constitutes rotation prevention means 9.

In the replacement cassette 3 alone not attached to the main body 2, the claw member 11 always engages with the ratchet teeth 10 on the outer periphery of the feeding reel of the rotation preventing means 9 of the feeding reel 4 to prevent the rotation of the feeding reel 4. Although not shown, in order to prevent reverse rotation of the take-up reel 5, the elastic claw on the upper surface of the take-up reel 5 meshes with the annular rack on the inner surface of the upper wall plate of the exchange cassette 3 to form a ratchet mechanism and take up. Since the reverse rotation prevention mechanism that prevents the reel 5 from rotating in the return direction is provided, the coating film transfer tape does not sag.

The main body 2 is provided with a feeding drive shaft 7 and a winding drive shaft 8, which are detachably attached to the feeding reel 4 and the take-up reel 5, perpendicular to the inner surface of the lower wall plate of the main body 2. , 8 is also provided for interlocking rotation, and the ratchet teeth 10 formed on the outer periphery of the feeding core 4 are released to disengage the claw member 11 provided on the inner surface of the lower wall plate of the replacement cassette 3. The ribs 12 also protrude perpendicularly to the inner surface of the lower wall plate of the main body 2.

Four of the eight protrusions formed on the inner peripheral surface of the supply reel 4 and directed in the center direction are engaged with the four protrusions of the drive shaft 7 for supply, and the inner peripheral surface of the take-up reel 5 Of the eight protrusions formed in the center and directed in the center direction, four protrusions engage with the four protrusions of the winding drive shaft 8 so that both reels and both drive shafts rotate without slipping.

When the use of the coating film transfer tape is finished and a new coating film transfer tape is refilled, the replacement cassette 3 that has been used is first removed from the main body 2, and when a new replacement cassette 3 is mounted on the main body 2, it automatically feeds out. The reel 4 and the take-up reel 5 are attached to the feeding drive shaft 7 and the take-up drive shaft 8, and at the same time, a release rib 12 having an inclined surface provided in the main body 2 is provided on the inner surface of the lower wall plate of the exchange cassette 3. The claw member 11 is inserted into the slit 13 on the side of the claw member 11 and moved in a direction to disengage the ratchet teeth 10 on the inclined surface to remove the claw member 11 from the ratchet teeth 10, so that the feeding reel 4 can be rotated and coated. The refilling of the film transfer tape is completed.

The mechanism for releasing the rotation blocking means 9 of the supply reel 4 is not limited to the inclined rib, but may be a conical protrusion or may use an electromagnetic force. In addition, the slope of the inclined surface is changed so that the main body side is looser than the front end side, and when the replacement cassette 3 is attached to the main body 2, the claw member 11 gradually becomes less engaged with the ratchet teeth 10 on the inclined surface. If the mesh is completely disengaged immediately before the main body 2 is completely attached, the replacement cassette 3 alone prevents the reel 4 from rotating and rotates while the replacement cassette 3 is about to be attached to the main body 2. The rotation prevention means 9 is released immediately before the end of the mounting.

The interlocking mechanism between the supply reel and the take-up reel is not limited to the belt, and it is sufficient that the gear and both reels can be in direct contact and rotate freely.
Even if the interlock mechanism is provided with both a drive shaft for feeding and a drive shaft for winding, the winding drive shaft is inserted into the take-up reel only by the feeding drive shaft, It may be simply interlocked with a gear.
The transfer tape may be a correction tape, an adhesive tape, a decorative tape, or a marker tape.
The transfer head may have a spatula shape or a roller shape, or may be provided on the main body side without being provided in the replacement cassette.
The exchange cassette may support the supply reel and the take-up reel rotatably with only the upper wall plate instead of the pair of upper and lower wall plates.
Even if the main body has a lid connected by a hinge or the like, the main body may have a configuration in which there is no lid and the lid is shared by mounting an exchange cassette.

(A) is the figure when the exchange cassette is not attached to the main body, (b) is the figure when the exchange cassette is attached to the main body and the rotation prevention means of the feeding reel is released. Partial view when done. FIG. 4 is a diagram showing only the outer shape of the replacement cassette attached to the main body shown by a solid line by a one-dot chain line.
