Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a back-applying device in which an adhesive tape is manually attached to the back of a booklet such as a form or a notebook in which slips are bound.

[0002]

2. Description of the Related Art In the case of performing back-adhesion processing in which an adhesive tape is attached to the back of booklets, and handling a large number of booklets of the same size, the applicant's prior invention (for example, Japanese Utility Model Publication No. 3-152).
As described in No. 38 and Japanese Patent Application No. 7-20356), an automatic back-applying device is used that automatically attaches an adhesive tape to the back of a booklet while sending it on a conveyor. Has been done.

However, in the case of handling a small amount of various kinds of booklets, a manual back-adhesion operation is performed rather than an automatic back-adhesion device, in which the operator performs the back-adhesion work while grasping and moving the booklets by hand. The device is useful. As a manual back-applying device, conventionally, a device as shown in FIGS. 14 to 16 has been used.

That is, in this conventional apparatus, a roll-shaped adhesive tape T is built in a box 80 having a rectangular shape in plan view, and the adhesive tape T is placed between the front and rear guide members 81 formed on the upper surface of the box 80. The booklet A grasped by a person is inserted between the front and rear guide members 81 so that the back surface of the booklet A faces downward, so that the adhesive tape T is attached to the back surface of the booklet A. In this state, the booklet A is slid horizontally until it hits the stopper 82, and the adhesive tape T is pulled out.

Then, the cutter 83 is reciprocally moved by the electromagnetic solenoid built in the box 80 as shown by the arrow B to cut the adhesive tape T. As a result, the adhesive tape T protrudes from both sides of the booklet. Stick on the back of A. Then, by inserting the booklet A with the adhesive tape T attached to the back surface between the pair of rubber rollers 84, the outwardly protruding portion of the adhesive tape T is attached to both front and back surfaces of the booklet A. It was done.

[0006]

However, in this prior art, since the booklet A is slid horizontally and the adhesive tape T is pulled out, the total length of the entire apparatus is at least twice that of the back surface of the booklet A. In addition to being the length of
Since a pair of rubber lauras 83 are provided, there is a problem that the entire size increases. Another problem is that the work efficiency is poor because two operations, namely, an operation of sliding the booklet A and an operation of inserting the booklet A between the pair of rubber rollers 83 are required.

It is an object of the present invention to provide a back attachment device which is compact and has improved work efficiency.

[0008]

In order to achieve this object, the present invention relates to "a table extending in a band shape in a plan view, and a front and rear guide body arranged above the table so as to extend parallel to the table. , A guide groove is formed so that the back of the booklet can be fitted from above, a positioning stopper for the booklet is provided at a portion near one end of the guide groove, and the other end of the guide groove is opened while the vicinity of the table is provided. In addition, a clamp body, in which the adhesive tape with the adhesive surface facing upward is pulled out from one end of the guide groove to the other end, is movably arranged along the longitudinal direction of the table. When the booklet is inserted into the guide groove in a downward position, set so that the cut adhesive tape sticks to the back of the booklet while protruding outside the front and back sides of the booklet. A cutter for cutting the adhesive tape pulled out by the clamp body is movably provided in the vicinity of the stopper so that the booklet can be pulled out from the other end in the guide groove at a position near the other end of the guide groove. The upright guide member is provided so that the outward protruding portion of the adhesive tape is raised upward by the sliding operation.

The operation of moving the clamp body and the operation of the cutter may be performed manually, or by an electric or mechanical means such as an electromagnetic solenoid.

[0010]

With this structure, by moving the clamp body and the cutter, the adhesive tape can be pulled out into the guide groove while being cut into the length dimension of the back surface of the booklet. The adhesive tape that has been cut to a specified length on the back of the booklet by cutting the adhesive tape to a specified length before or after pulling out the adhesive tape and inserting the booklet into the guide groove. You can Then, by sliding the booklet and pulling it out from the guide groove, the adhesive tape can be attached in a state of being wound around the back surface and the front and back surfaces of the booklet.

However, since the adhesive tape is drawn in advance into the guide groove by a predetermined length, the lateral length of the guide groove (the lateral width of the front and rear guide bodies) is larger than the maximum length of the back surface of the booklet. It only needs to have a certain length. Also,
Simply insert the booklet in the guide groove, slide it, and pull it out of the guide groove.The adhesive tape is attached to the back and front and back sides of the booklet in a folded state. Since the adhesive tape can be attached to the back surface of the device and the bending attachment to both the front and back surfaces can be performed at the position of the guide groove, the depth dimension (front-rear width dimension) of the device can be shortened. By reducing the left-right length and the depth, the overall size can be reduced.

Further, the adhesive tape can be attached to the back and front and back sides of the booklet by a one-touch operation of inserting the booklet into the guide groove and sliding it. The efficiency of sticking work can be improved compared to
