DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eraser main body comprising a supply reel and a take-up reel for continuously winding a modified paint transfer tape fed from the supply reel. And a transfer head for transferring and applying a correction paint layer of the correction paint transfer tape to an erasing portion between the correction paint transfer tape and the correction paint transfer tape. .

[0002]

2. Description of the Related Art As disclosed in Japanese Utility Model Laid-Open Publication No. 7-28146, for example, a cylindrical portion provided at the tip end of a erasing tool body has a multilayer structure, and one member of the multilayer structure is attached to the other member. In some cases, the transfer head is mounted so as to be slidable.

[0003]

In the above-mentioned conventional example, specifically, a protrusion provided on the outer surface of a protective cylinder is provided by sliding a protective cylinder on the cylindrical portion of the eraser main body. The protection cylinder engages with a guide groove provided on the inner surface of the cylindrical portion, moves the protection cylinder forward and backward with respect to the cylindrical portion by movement of the projection along the guide groove, and covers the transfer head when moving forward. However, since the contact resistance of the projections with respect to the guide grooves is used as means for maintaining the mounted state of the transfer head by the protective cylinder, the mounted state is easily released,
There is a possibility that the protection function of the transfer head cannot be fulfilled.

[0004]

A supply reel and a take-up reel for continuously winding a correction paint transfer tape fed out from the supply reel are provided in the eraser main body, and the supply reel and the take-up reel are connected to each other. A transfer head for transferring and applying the correction paint layer of the correction paint transfer tape to the erasure portion between the correction paint transfer tape and the eraser protruding from the tip of the eraser body. A guide portion provided with a transfer head at a tip of a support member derived from the eraser main body through an end of an opening of the tubular portion, and a protection cylinder for covering the transfer head provided on the support member. Slide into
The sliding contact surface between the guide portion and the protection cylinder has a configuration in which projections and depressions are engaged with each other when the transfer head is mounted on the protection cylinder.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a transfer head protection device for an eraser body according to the present invention. FIG. 1 is a partially cutaway front view showing an eraser body opened and FIG. 1 is a cross-sectional view taken along line XX, FIG. 3 is a cross-sectional view of a protection cylinder, and FIG. 4 is a front view of a support member.

In the eraser A of the embodiment, a supply reel 2 and a correction fed out from the supply reel 2 are provided on a hollow eraser body 1 formed by fitting one half member 1a and another half member together. An apparatus substrate 4 rotatably supported on each of the take-up reels 3 for continuously winding the paint transfer tape a is provided. A tip of a support member 5 having a base mounted on the apparatus substrate 4 is attached to the main body 1. It is led out from the opening end of the tubular portion 6 through the tubular portion 6 having a cross-sectional direction arranged on the tip side, and the corrected paint layer of the corrected paint transfer tape a is erased (at the paper surface or the like) at the tip. A transfer head 7 for transfer coating is provided, and a modified eraser transfer tape a is pressed against an erasing position using the transfer head 7, and a eraser body is provided along the longitudinal direction of the transfer tape a. When 1 is moved by an appropriate amount, the transfer tape a The used transfer tape a which has been unwound from the supply reel 2 and from which the correction paint film has been peeled off is wound on a take-up reel 3 interlocked with the supply reel 2 by meshing with a gear, and the correction paint film is formed on the erasure portion. After painting, a so-called erase operation is performed.

The support member 5 has guide portions 8, 9 having an H-shaped cross section near the middle portion in the longitudinal direction and the tip portion on the side of the transfer head 7, and side pieces 8a, 8a, 9a of the guide portions 8, 9 are provided. , 9a, the intermediate portion between the two reels 2, 3 of the corrected paint transfer tape a is engaged to guide its movement, while the inner surface of the protective cylinder 10 is slid on the side pieces 8a, 9a. In this way, the protective tube 10 is slidably fitted to the guide portions 8 and 9 and assembled to the support member 5.

The protective cylinder 10 has a rectangular cross section and is interposed between the cylindrical portion 6 having a rectangular cross section and the support member 5 so as to slide on the guide portions 8 and 9 of the support member 5 to move. As shown in FIG. 3, the slit 1 extends from the rear end to the front end.
1 and one piece 10a partitioned by the slit 11
The support member 5 is provided with elasticity so that it comes into sliding contact with the side piece 8a of the guide portion 8 at the intermediate portion of the support member 5.

The side pieces 8a, 8a of this piece 10a
A protrusion 12 is provided on a portion facing the surface (that is, a sliding contact surface with the side piece 8a), and when the protrusion 12 is locked by the locking portion 13 on the front side, the protection cylinder 10 moves forward. The transfer head 7
When the protective cylinder 10 is retracted from the transfer head 7,
The protrusion 12 is locked to the locking portion 13 'on the rear side to maintain the retracted state.

In the embodiment, the protrusion 12 is connected to the protection cylinder 10.
The locking portions 13 and 13 ′ are formed on the support member 5 side, but may be formed in the opposite manner. Protection tube 10
It is only necessary to secure the fixed position and maintain the state in which the transfer head 7 is covered by the protective tube 10.

Reference numerals 14 and 14 denote bulging portions provided on the opposite side surfaces of the protective cylinder 10, and the moving operation of the protective cylinder 10 is performed such that a fingertip is hooked on the bulging portions 14 and 14. .

[0012]

The present invention has the configuration described above,
By simply sliding the protective cylinder, the mounted state of the transfer head can be easily obtained, and in the mounted state, the unevenness provided on the guide portion of the support member and the sliding contact surface of the protective cylinder are mutually different. Since it is locked, the protection cylinder can maintain a fixed position without moving and maintain the mounted state of the transfer head.
