At this time, since the first solenoid 26 is in the OFF state, the plunger 27 descends due to its own weight and engages with the bottomed hole 29 of the rotor 22, as shown in FIG. Therefore, the rotor 22 cannot be rotated using the key 10.

Further, since the lowered portion of the engagement piece 32 rotates while being engaged with the engagement recess 13 of the key 10, the upper end of the engagement piece 32 is pressed against the inner circumferential surface of the case 21, so that the key 10 is not engaged. Since the key 10 is locked to the coupling piece 32, the key 10 cannot be pulled out. That is,
When the key 10 is rotated by 90 degrees, the rotor 22 cannot be turned by the key 10, nor can the key 10 be pulled out.

In FIG. 1, the number "104" on the display board 3 indicates when the key 10 is inserted, "105" indicates the number when the key 10 is rotated 90 degrees in the direction of arrow A, and "106" indicates the number indicated by the rotation knob 41.
This shows the case where the door 2 is opened by rotating it in the direction of arrow B to unlock it.

Next, the case of closing the door 2 will be explained. As shown in FIGS. 5 and 6, when the door 2 is closed and locked by turning the rotary knob 41 in the direction opposite to the direction of arrow B, the door switch 8 and the second switch 49 are turned on. At this time, if you press the changeover switch 7 to switch to the contact b side in Fig. 7, the power supply E → door switch 8 →
Since the circuit of second switch 49→changeover switch 7→first solenoid 26 is established, first solenoid 26 is operated and plunger 27 is pulled up. Therefore, the plunger 27 is disengaged from the rotor 22 and the key 10 can be rotated. When the key 10 is turned in the direction opposite to arrow A and returned to the original position shown in FIG. 3a, the plunger 27 is engaged. The piece 32 is now movable and the key 10 can be withdrawn. At the same time, when the first switch 33 is turned off by rotating the rotary lever 24, the plunger 45 and the engagement piece 46 of the second solenoid 44 are lowered and engaged with the engagement recess 47, as shown in FIGS. As a result, the rotation knob 41 cannot be rotated. At the same time, when the press of the changeover switch 7 is released, the switch is switched to the contact a side shown in FIG. 7, the first solenoid 26 is turned off, and the locking of the door 2 is completed.
