BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a poster panel board which can hold a poster and display and advertise the poster, and in particular, a poster with an anti-theft function which automatically locks the inserted poster so that it cannot be easily removed. It relates to a panel board.

[0002]

2. Description of the Related Art A conventional panel board of this kind is
It is common to use a method in which a poster is sandwiched between the front and back frames, and the both frames are fixed with screws.

Recently, as shown in, for example, Japanese Utility Model Application Laid-Open No. 63-103471 developed by the present applicant, a rectangular frame provided with an opening groove and a U-shaped cross-sectional groove therein is used. There is also known a panel board in which a poster can be easily stored by inserting the poster into the rectangular frame.

[0004]

Although the above-described panel plate composed of the front and back frames has a simple structure, the poster is accurately sandwiched between the front and back frames, and The work was troublesome because it had to be fixed with screws.
In addition, every time the poster is replaced, the front and back frames must be disassembled or assembled, resulting in a problem that the operation becomes extremely complicated.

[0005] Further, the poster panel plate composed of a rectangular frame having an opening groove and a U-shaped cross-sectional groove inside the latter developed by the present applicant makes it easy to put the poster in and out of the panel plate. A locking piece with a hole is protruded at the tip of the poster stored in the board, and a projection is provided on the ceiling surface of the frame at the back edge of the frame. Although the projection is fitted into the hole of the provided locking piece to lock the poster, the poster formed mainly of paper is flexible and has a U-shaped concave groove in which the poster is inserted. The upper and lower widths are formed with a certain margin even when the poster is inserted, so it is difficult to ensure that the protrusion provided on the ceiling of the U-shaped concave groove is securely inserted into the hole of the locking piece of the poster Met. Therefore, it was difficult to completely lock the poster inserted in the panel board to the panel board. Therefore, the stored poster can be easily removed from the panel plate, and there is a problem that the poster is suitable for theft.

In the latter technique, a locking piece having a hole is protrudingly provided at the front end of the poster. Therefore, in order to store the locking piece, the rear edge of the frame is unnecessarily wide. I had to make it wider. Further, when the back edge is widened, the opening edge must be widened on the appearance of the frame, and there is a problem that the cost is increased.

The poster panel board according to the present invention is a completely new technique developed in view of the above-mentioned conventional problems, and in particular, can automatically lock a poster stored in the panel board, and Once locked, posters offer a completely new technology with features that cannot be easily removed by ordinary people who do not know the locking mechanism.
