Seven pairs of pin fitting holes 3a are formed as through holes so as to be opposed to each other. The engagement pin is fitted into this fitting hole. The shaft portion of the engagement pin is fitted and supported in the bearing portion 3b of the engagement pin. 3c is a protrusion formed on the side and the rear except the front, and the protrusion on the side acts as a card engaging portion.

3 A, B, C and D show a plurality of different types of engaging pins of the present invention, A is a side view of one kind, B is a side view of another kind, and C and D are A and B It is a top view of each engagement pin shown in FIG. Numerals 4 and 5 are resin-molded heterogeneous engagement pins forming a head which is an engagement portion with a card and a protrusion which is an engagement portion with a fixing plate. These engaging pins differ in the locations where the projections 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, 5b are housed in the pin bearing portion 3b of the slide plate, are supported by the spring body 3d and are rotatably supported by the pin insertion hole of the slide plate, and are appropriately inserted in the pin insertion hole of the fixed plate. The engagement pin disengages. More locks can be made by increasing the type or number of engaging pins.

4A and 4B are schematic plan views of the lock member that is moved directly or indirectly by the slide plate 3.

The lock member 6 is a molded product of synthetic resin, and has a locking portion 6a at one end and a shaft engaging hole 6c at the other end with a slider engaging portion 6b 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. 5 shows a plan view of the card. The card 7 only needs to have a size and thickness such as a cash card and a business card, and is made of resin having a certain degree of hardness. A fitting hole 7a for an engagement pin is formed in this card as appropriate. In other words, by pushing down any one of a plurality of different types of engaging pins with the card, the engaging pin is rotated and pushed down, and another type is pushed into the fitting hole 7a. By keeping the state that it is not present, all the engagement pins are released from the engagement of the slide plate and the fixed plate, the slide plate becomes movable, and the projection of the slide plate (card engagement part ) 3c is pushed to move the engaging portion 6b of the lock member 6 by means of the slide plate. Therefore, a satisfactory combination of the card provided with the desired insertion hole 7a and the corresponding desired engagement pin will release the engagement with the fixed plate of the slide plate, and slide the slide plate. It can be unlocked, but other cards cannot be slid because the slide plate cannot be disengaged.

Reference numeral 10 denotes a card insertion hole formed on the opposite side of the fixed plate with the slide plate sandwiched therebetween, and the engagement pin 4 has the protrusion 4a located at the insertion hole of the slide plate, so that the slide plate can be moved. 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. 7 shows a 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.
When the engaging pin is pushed down by the card, the state becomes a dotted line, and the projection 5a moves out of the position of the fitting hole 2, and the slide plate can move.

FIG. 8 shows a state in which the slide plate 3 is moved to the right by the card 7 and at the same time the lock member 6 is moved (see FIG. 4B).
Indicates. In this case, the unlocked state is obtained, and the locking portion of the locking member 6
6a is housed in the fixed plate 1. That is, the engagement with the locked portion 11 is released.

FIG. 9 shows the state of the perspective view of FIG. A case 9 is attached to the fixed plate 1 to form a flat box shape. Reference numeral 11 is a locked portion (key portion).

(Effect) The card lock of the present invention has the following effects.

(1) One card can be locked or unlocked by inserting it into the card insertion hole and then moving it in the sliding direction of the slide plate. Therefore, the operation is performed only by moving the hand holding the card. Is very easy.

Further, it goes without saying that the fixing plate having the pin fitting hole can be used also as the case main body to be manufactured, and the number of members is reduced, leading to cost reduction.

(2) Since the spring body that rotatably supports the engaging pin is integrally formed on the slide plate, if this slide plate is made of synthetic resin, it is lightweight and low in cost. Rotational variation is smaller than that of a separate body and it is easy to assemble.

(3) Since the card is always carried by itself like a cash card, there is no concern that the code such as a push-button lock will be detected.
