A fixed plate 8 is provided with a plurality of engaging pins arranged side by side and rotatably supported. Reference numeral 8a is a fitting hole for the engaging pin, and six holes 8a are formed at the same intervals so as to coincide with the pin fitting hole 4b. These pin fitting holes 8a sequentially form a cylindrical groove 8b at one end or the other end into which a spring urging the engaging pin is inserted. Reference numeral 8c is a pivot hole of the engaging pin. 9,
Reference numeral 10 denotes engaging pins having different shapes, 9a and 10a are shaft holes, 9b and 10b are engaging portions with a card, and 9c and 10c are engaging portions with a slide plate. This engagement pin is in a state where the engaging portion with the slide plate is engaged with the pin insertion hole of the slide plate, that is, the state where the slide plate is prevented from sliding, and the engagement pin does not engage with the pin insertion hole of the slide plate. In the assembled state, there are those in which the sliding of the slide plate is not blocked. Therefore, the slide plate can be slid if the engagement pin engaged with the slide plate is pushed by the engagement card to release the engagement with the slide plate. Reference numeral 11 is a holding plate, and 11a is a pin fitting hole, which is formed in substantially the same manner as the pin fitting hole of the slide plate. Reference numeral 12 is a substantially L-shaped pushing metal fitting, and 13 is a lock member. The member is substantially L-shaped and has a fitting hole 13a into which the locking rod can be engaged and disengaged. In FIG. 8, 5 is a lock rod, and 6 is a chain-like portion composed of a connecting chain.

A state in which the above members are incorporated will be described with reference to FIGS.
A box-shaped lock body 1 having a card insertion slot 2 is provided with a slide plate 4 on the side opposite to the card insertion slot with a fixed plate 8 interposed therebetween so as to be slidable in the arrow direction. Reference numeral 14 denotes a spring, which presses the L-shaped lock member 13, and the member is pressed against the engagement piece 4c. Therefore, when the slide plate is pushed in the direction of the arrow, the lock member is directly or indirectly linked. Then, the head of the lock rod 5 inserted through the insertion opening 1a of the lock body is inserted into the insertion hole 13a, and is pressed in the direction of the arrow while being in contact with the push fitting 12 pressed by the spring 15. ing. That is, the head portion of the lock rod is engaged with the peripheral edge of the fitting hole 13a in a pressed state in the arrow direction via the spring. That is, the locked state is maintained.

According to the above description and the drawings, when the card is inserted through the card insertion slot 2, the engagement pin engaging with the pin insertion hole of the slide plate, for example, the engagement pin 10, has an engagement portion with the card. It is pushed down by the engagement card, and the engagement with the pin fitting hole is released. Further, the other engaging pins that are not engaged with the pin inserting holes of the slide plate are in a state where the engaging portion with the card is inserted into the hole of the engaging card and is not pushed. Therefore, when the grip portion 4a of the slide plate is gripped and the slide plate is pushed in the direction of the arrow, the engaging piece 4c integral therewith also moves, whereby the lock member 13 is pushed against the spring 14. At this time, the head of the locking rod 5 is the spring 15
Since it is constantly pressed by the pushing metal member by the urging force of, it escapes from the fitting hole 13a. That is, the lock member 13 and the lock rod 5
Is disengaged. It is in the so-called unlocked state. In this case, if you release your hand from the handle of the slide plate, the spring 1
The lock member 13 is pressed by the urging force of 4 and the slide plate returns to the original position. In this embodiment, the lock rod 5 is locked to the lock member by inserting the lock rod 5 through the insertion opening 1a of the lock body and further inserting it into the insertion hole 13a of the lock member, so that the head portion thereof engages with the periphery of the insertion hole. I keep it locked. Reference numeral 16 is a shaft on which the engaging pin is rotatably supported by the fixed plate, and 17 is a spring, which urges the engaging pin in a downward direction.

In FIG. 10, the engagement pin 9 is rotatably attached to the shaft 16 of the fixed plate 8, and is disengaged from the pin fitting hole 4b of the slide plate 4, that is, the slide plate is not engaged. It shows the state that it can slide. Further, since the engaging portion 9b of the engaging pin with the card is fitted into the hole 7a of the card 7, it is not pushed down by the card.
Reference numeral 11 is a holding plate. Reference numeral 17 denotes a spring which is inserted into the cylindrical groove 8b and urges the other end of the engaging pin in a direction to push it down.

FIG. 11 shows a state in which the engaging pin is pushed down by a non-perforated portion of the card 7 and the engaging portion 9c is fitted and engaged in the pin fitting hole 4b of the slide plate. That is, the slide plate cannot be moved. The engagement pin and the slide plate maintain the engagement state as in the above structure depending on the pushing state of the engagement pin by the card, and become the unlocked or locked state.
