Reference numerals 4 and 5 are resin-molded heterogeneous engagement pins. These engaging pins differ in the locations where the protrusions 4a and 5a are formed, and the shaft portions 4b and 5b
Have the same shape. The protrusion 4a is formed on the upper part of the main body, and the protrusion 5a is formed on the lower part of the main body. The shaft portions 4b and 5b are housed in the pin bearing portion 3b of the slide plate, supported by the spring body 3d and rotatably supported by the pin insertion hole of the slide plate, and properly engaged with the pin insertion hole of the fixed plate. The dowel pin disengages. More locks can be made by increasing the type or number of engaging pins.

5A and 5B are schematic plan views of the lock member that is directly or indirectly moved by the slide plate 3.

The lock member 6 is a molded body of synthetic resin, and has a locking portion 6a at one end, an engaging portion 6b of a slide plate at the other end, and a shaft hole 6c in the middle. A indicates a state in which the locking portion 6a is projected, that is, a locked state. B shows a state in which the engaging portion 6b is pressed by the slide plate 3 and the lock member rotates in the direction opposite to A, that is, a so-called unlocked state.
The spring 8 biases the rotation of the lock member.

FIG. 6 shows a plan view of the card. The card 7 need only be of a size and thickness such as a cash card or a business card, and is made of resin having a certain degree of hardness. In this card, a fitting hole 7a for the engaging pin and a fitting hole 7b for the hooking pin 11 are appropriately formed. That is, when the card is inserted from the card insertion port, one of a plurality of different types of engaging pins is pushed down by the card, and the engaging pin is rotated to rotate the engaging pin and the fixing plate. Is disengaged from the fitting hole. On the other hand, by inserting another type into the insertion hole 7a and keeping it in the same state without being pushed down, the projections of all the engaging pins are located on the insertion hole side of the slide plate, and the engagement between the slide plate and the fixed plate Is released, the slide plate becomes movable, and the hook pin is pushed down by the card. Then, the slide plate, that is, the card engaging portion 3c is pushed in the horizontal direction together with the card to move the engaging portion 6b of the lock member 6 by the slide plate. At that time, the insertion hole
The hooking pin 11 is fitted into 7b to be hooked. Therefore, a card having a desired insertion hole 7a, 7b and a desired combination of a corresponding engaging pin and a corresponding hooking portion can be unlocked by sliding the slide plate and the card can be hooked up. Via the fixed plate, that is, the door, is engaged.

FIG. 7 shows a schematic cross-sectional view of a state in which the above-mentioned members are assembled. The fixed plate 1 has a hook pin 11 engaging pins 4 and 5 (5 is not shown), a slide plate 3 a lock member 6 (not shown), a spring 8 (not shown) for urging the lock member, and the like. , Case 9 is provided. 10 is a card insertion port, and the head of the hooking pin projects to the position of the card insertion port, but it is pushed down by the insertion of the card and is elastically deformed. Since the projection 4a of the engagement pin 4 is located at the position of the fitting hole of the slide plate, the slide plate is movable and is in the unlocked state. When the projection 4a is lowered while the head 4c of the engaging pin is pushed down by the card and rotated to the position of the dotted line, the projection 4a is located in the pin insertion hole 2 of the fixed plate 1 and the slide plate cannot move.

FIG. 8 shows the difference when the engaging pin is different from that of FIG. Since the projection 5a of the engagement pin 5 is located at the position 2 of the pin fitting hole of the fixed plate 1, the slide plate cannot move.
