It consists of a pivoted rotor 19b. The swing link 19a is pivotally supported at a substantially central position by the slide plate 26, and is biased to a neutral position by a torsion spring 19d wound around a pivot 19c. The rotator 19b is provided with a slide plate 26 and a pair of operation protrusions 19e that penetrate the bottom plate 1b and reach the back surface of the bottom plate 1b at symmetric positions, and are rotated by the lock operation unit 4 via the operation protrusions 19e. Direction. When the swing link 19a is lowered with the lowering of the card lock unit 10, one of the bottom sides is shifted from the center of the rocking, and one of them is in contact with the operation protrusion 19e on the side located exactly above, and when the base is further lowered, As shown in FIG. 4 (b), the swing link 19a pushes down the operation projection 19e while swinging toward the operation projection 19e with which it abuts, and moves the rotor 19b in a predetermined direction, that is, the operation on the abutment side. The projection 19e rotates in a direction in which it is pushed down. The operation protrusion 19e on the non-contact side moves upward due to the rotation of the rotor 19b, but the swing link 19a swings toward the operation protrusion 19e on the contact side. There is no interference with the operation projection 19e on the contact side. The slide plate 26 is provided with a vertically long insertion hole 26b so that the operation protrusion 19e does not interfere when the slide plate 26 descends. As shown in FIG. 4C, in a state where the card lock unit 10 has returned to the original position, the operation protruding portion 19e symmetrically positioned with respect to the depressed side is located at an upper position, and thereafter, the card lock is returned again. When the unit 10 is lowered, the swing link 19a contacts the upper operation protrusion 19e and then pushes down the operation protrusion 19e on the contact side, that is, reverse to the previous operation, as described above. The rotor 19b is rotated in the direction.
