DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock mechanism for a paper box such as a cash box.

[0002]

2. Description of the Related Art A conventional lock mechanism for a paper sheet storage box of this kind has a structure in which the lock is released when the storage box is inserted into a main body. Specifically, a special sword for unlocking the storage box is arranged on the main unit side, and a hole etc. is provided in the storage box for the sword to enter. Engages with the lock mechanism inside the storage box, and the lock is released (the shutter for taking in and out of paper sheets is opened).

[0003]

However, in the above-mentioned conventional structure, there is a problem that the engagement between the sword and the lock mechanism is not reliably performed due to a variation in manufacturing parts, and the internal structure is damaged due to foreign matter insertion. There were various problems.

SUMMARY OF THE INVENTION An object of the present invention is to provide a lock mechanism for a paper sheet storage box having a simple structure and capable of reliably releasing the lock and having excellent anti-theft properties.

[0005]

In order to achieve the above-mentioned object, according to the present invention, in the case of a sheet alone, the shutter of the sheet storage box is locked in a closed state, and the sheet storage box is attached to the main body. A movable suction lock that releases the lock of the shutter by the insertion operation and moves the shutter to the open position to lock the shutter to the paper storage box in the closed state in the paper storage box locking mechanism. A movable repulsion lock member provided with a member and a magnet, and when the paper sheet storage box is inserted into the main body by a predetermined amount, the suction lock member is opposed to the suction lock member, and the suction lock member is sucked. A first magnet for releasing the lock, and the same polarity as the magnet of the repulsion member, facing the magnet of the repulsion lock member when the paper sheet storage box is inserted into the main body by a predetermined amount; A second magnet for releasing a lock of the shutter by separating a lock member, and further inserting the paper sheet storage box into the main body after the suction lock member and the repulsion lock member release the lock of the shutter. A claw that engages with the shutter to move the shutter to a closed position when the shutter is closed, and further, does not lock the shutter in the sheet storage box in a normal state of the sheet storage box,
When the paper sheet storage box is turned upside down, the paper sheet storage box is moved by its own weight to lock the shutter, and is constituted by a member that is not attracted by the magnet. A configuration is provided in which a weight lock member is provided.

[0006]

When the paper sheet storage box is not inserted into the main body, the shutter is securely locked because the suction lock member and the repulsion lock member lock the shutter. Moreover, since the repulsion lock member is also used, it is difficult to release the lock using a magnet or the like. Further, if the storage box is turned upside down in order to somehow release the lock of the storage box, the lock becomes more difficult because the self-weight lock member mechanically locks the shutter.

[0007]
