JPH10181288A - Protection cover for rolling adhesive-tape head - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the retracting movement of a protection member by providing a protection member adapted to be advanced and retracted between a first position for protecting a rolling adhesive tape head and a second position retracted from the rolling adhesive-tape head, the protection member being constructed so as to be retracted to the second position when a leading end thereof is shifted through a predetermined angle from the first position. SOLUTION: When a rolling adhesive tape head 24 is protruded relative to a protection cover 25, i.e., the protection cover 25 is shifted rearwardly, a leading end of the protection cover is pintched with the fingers to be moved such that a protruding portion 53 comes off from a first locking area 58. Subsequent to this, the protruding portion 53 is displaced so as to be located within a slit portion 53, whereby it can be pushed in a direction in which the protection cover 25 is retracted. Continuation of this pushing operation causes the protruding portion 53 to be fitted in a second locking area 59, which functions to regulate the movement thereof in a second position. Thus, it is possible to perform required rolling adhesion thereafter.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective cover for a transfer tape head, and more particularly, to a protection cover for a transfer tape head which can always be stably maintained when the transfer device is not used. In particular, the present invention relates to a protective cover for a transfer tape head that can effectively prevent transfer of a transfer agent to clothes when the transfer device is stored in a pocket such that the transfer tape head faces downward.

[0002]

2. Description of the Related Art Conventionally, a transfer tape capable of performing a required transfer to a transfer tape having a transfer agent formed of a white film used for correcting a typographical error, or a transfer tape having an adhesive laminated thereon. Kimono is known. In this type of transfer device, the transfer tape wound around the pay-out roller is wound around the transfer roller in the reverse direction by a transfer head, and the lead end thereof is fixed to a take-up roller, thereby winding the used transfer tape. It is provided to be able to take.

When the transfer tape head is not in use,
A protective cover made of a cap or the like is attached so that the transfer agent does not come off in contact with an unintended part. As the most common protective cover, a fitting type that can simply cover the front end side of the transfer tape head is known.

[0004]

However, in such a fitting-type protective cover, the work of attaching and detaching the protective cover must be performed every time the transfer device is used, which is troublesome. In addition, there is a disadvantage that the protective cover is easily lost.

[0005] Therefore, a slide-type protective cover that does not require attaching and detaching work of the protective cover has come to appear. The protective cover is set at a position where the protective cover protrudes from the front end side of the case in a state where the transfer device is not used, and when the transfer device is used, the protective cover is moved backward to transfer the transfer tape. The head can be made to protrude relatively to the protective cover.

However, in this type of protective cover, when an external force is applied to the tip of the protective cover in a direction to retract the protective cover, the transfer tape head easily projects relatively. It is a mess. Therefore, for example, when a similar protective cover is provided on a pen-type transfer device, the protective cover moves backward at the bottom of the pocket, and as a result, the transfer agent of the transfer tape is removed from the pocket. This causes the disadvantage that the film is easily peeled off at the bottom of the film.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of such inconvenience, and its object is to protect the transfer tape head even when an external force is applied in the retreating direction. It is an object of the present invention to provide a protective cover for a transfer tape head that is allowed to retreat under the condition that a force for shifting a position in a predetermined direction is applied.

[0008]

According to the present invention, there is provided a protective cover for a transfer tape head in a transfer device, wherein the cover is mounted on a case holding the transfer tape head. A protection member capable of moving back and forth between a first position for protecting the transfer tape head and a second position for retreating with respect to the transfer tape head, wherein the protection member has a first end on the first side. It is configured to be provided so as to be able to retreat to the second position when shifted from the position by a predetermined angle. By adopting such a configuration, as a condition for retracting the protection member to the second position,
It is necessary to apply an external force for shifting the protection member by a predetermined angle from the first position. Even if a force is simply applied in a direction to retract the protection member, the protection member can be prevented from retreating. Therefore, for example, when the protective cover in the present invention is applied to a pen-type transfer device and the transfer device is used as a pocket storage type, inadvertent peeling of the transfer agent by the bottom of the pocket is effective. Can be prevented.

[0009]

In the protective cover of the transfer tape head, the moving member includes a pair of slide pieces located on an outer surface side of the case, and an inner surface of the slide pieces is formed on the case. And a projection guided by the arcuate slit connected to the linear slit is provided, and the projection is formed by a first engaging portion formed in a continuous portion between the linear slit and the arcuate slit. It is preferable to adopt a configuration in which a stop region and a second lock region provided on the rear end side of the linear slit portion are respectively provided so as to be lockable. As a result, the projection of the slide piece is locked in the first locking area, so that a stable protected state can be always maintained unless an intentional external force is applied to release the locked state.
