Description

[0001]
[Industrial application fields]
According to the present invention, a supply reel and a take-up reel for continuously winding a correction paint transfer tape fed out from the supply reel are arranged on the eraser body, and the correction paint is provided between the supply reel and the take-up reel. The present invention relates to an eraser transfer head protection device in which a transfer head for transferring and applying a correction paint layer of a transfer tape to an erasing portion is projected from the tip of the eraser body.
[0002]
[Prior art]
For example, as disclosed in Japanese Utility Model Laid-Open No. 7-28146, the cylindrical portion provided on the tip side of the eraser main body has a multi-layer structure, and one member of the multi-layer structure is slidable with respect to the other member. Some have a transfer head.
[0003]
[Problems to be solved by the invention]
Specifically, the above-described conventional example is a guide in which a protective cylinder is slid onto the cylindrical portion of the eraser main body, and a protrusion provided on the outer surface of the protective cylinder is provided on the inner surface of the cylindrical portion. The protection cylinder is moved forward and backward with respect to the cylindrical portion by engaging with the groove and moving along the guide groove of the protrusion, and the transfer head is mounted when moving forward. Since the contact resistance with respect to the guide groove of the protrusion is used as a means for maintaining the mounted state, the mounted state is easily released, and there is a possibility that the protection function of the transfer head cannot be achieved.
[0004]
[Means for Solving the Problems]
The eraser body is provided with a supply reel and a take-up reel for continuously winding the correction paint transfer tape fed out from the supply reel, and the correction paint transfer tape is corrected between the supply reel and the take-up reel. In the eraser in which a transfer head for transferring and coating the coating layer to the erasing portion is projected from the tip of the eraser body, a cylindrical part is provided on the distal end side of the eraser body, and the cylindrical part A transfer head is provided at the front end of the support member led out from the eraser main body through the front end of the opening, and a protective cylinder for mounting the transfer head is slidably fitted on a guide portion provided on the support member. The sliding surface of the protective cylinder is provided with irregularities that are locked to each other when the transfer head is mounted by the protective cylinder.

【Example】
FIG. 1 shows an embodiment of a transfer head protecting device for an eraser body according to the present invention, FIG. 1 is a partially cutaway front view showing the eraser body opened, and FIG. X-ray sectional view, FIG. 3 is a sectional view of a protective cylinder, and FIG. 4 is a front view of a support member.
[0006]
The eraser A according to the embodiment includes a supply reel 2 and a modified paint transfer tape fed from the supply reel 2 to a hollow eraser body 1 configured by fitting one half member 1a and another half member together. a device substrate 4 rotatably supporting each of the take-up reels 3 for continuously winding a, and the front end of the support member 5 having the base portion assembled to the device substrate 4 is connected to the front side of the main body 1 It is led out from the opening tip of the cylindrical portion 6 through the cylindrical portion 6 arranged in the direction of the cross section, and the correction coating layer of the correction coating transfer tape a is transferred and applied to the erasing portion (such as paper surface) at the tip. The transfer head 7 is provided so that the correction paint transfer tape a is pressed against the erasing portion using the transfer head 7 and an appropriate amount of the eraser main body 1 is placed along the longitudinal direction of the transfer tape a. When moved, the transfer tape a is supplied to the supply reel 2. The used transfer tape a part, which has been fed out and the correction coating film is peeled off, is wound around the take-up reel 3 interlocked with the supply reel 2 by meshing the gear, and the correction coating film is applied on the erasure point. Thus, a so-called erase operation is performed.
[0007]
The support member 5 is provided with guide portions 8 and 9 having an H-shaped cross section near the longitudinal intermediate portion and the tip on the transfer head 7 side, and between the side pieces 8a, 8a, 9a and 9a of the guide portions 8 and 9. The correction paint transfer tape a is engaged with the intermediate portion between the reels 2 and 3 to guide its movement, while the side pieces 8a and 9a are in sliding contact with the inner surface of the protective cylinder 10. The protective cylinder 10 is slidably fitted to the guide portions 8 and 9 and assembled to the support member 5.
[0008]
The protective cylinder 10 has a square cross section and is interposed between the cylindrical section 6 having a square cross section and the support member 5 so as to be in sliding contact with the guide portions 8 and 9 of the support member 5. As shown in FIG. 3, a slit 11 is provided in the front end direction from the rear end, and elasticity is imparted to one piece 10 a partitioned by the slit 11 so that the side piece of the guide portion 8 in the intermediate portion of the support member 5 is provided. It is in sliding contact with 8a.
[0009]
A protrusion 12 is provided on a portion of the piece 10a facing the side pieces 8a and 8a (that is, a sliding contact surface with the side piece 8a), and the protrusion 12 is provided on the locking portion 13 on the front side. When locked, the protective cylinder 10 moves forward and holds the transfer head 7 in a vertical state. When the protective cylinder 10 moves backward from the transfer head 7 portion, The protrusion 12 is locked to the locking portion 13 ′ on the rear side to maintain the retracted state.
[0010]
In the embodiment, the protrusion 12 is provided on the protective cylinder 10 side, and the locking portions 13 and 13 ′ are formed on the support member 5 side. The concave and convex portions are provided and locked to each other, the protective cylinder 10 is secured at a fixed position with respect to the support member 5, and the covering state of the transfer head 7 by the protective cylinder 10 is maintained.
[0011]
14 and 14 shown in the figure are bulging portions provided on the opposite side surfaces of the protective cylinder 10, and the protective cylinder 10 is moved so as to be hooked on the bulging parts 14 and 14.
[0012]
【The invention's effect】
Since the present invention is configured as described above, it is possible to easily obtain the mounted state of the transfer head simply by sliding the protective cylinder, and in the mounted state, Since the projections and depressions provided on the sliding contact surface of the protective cylinder are locked to each other, the protective cylinder can maintain a fixed position without moving and maintain the mounted state of the transfer head.
