When b opens, the guide presses safety tissue 9 with his hand,
When the safety tissue 9 is pressed, the links 9a and 9b rotate and the microswitch 10 is activated, the normally closed contact 1
0a is opened and the circuit of P-8a-10a-15-N is opened, so the door reversal command relay 15 is deenergized and the normally closed contact 1
5a is closed, the door reversing circuit 16 is operated by the circuit P-15a-16-N, and while the safety tissue 9 is being held down by hand, the car doors 3a, 3b and the landing door 4a are closed.
, 4b remain open, so the important visitor will not bump into the car doors 3a, 3b and the landing doors 4a, 4b, and the guide will not be able to keep his/her arm pushing the safety tissue 9 extended. It is possible to guide important guests in a natural state.

じることができる。On the other hand, when the car doors 3a, 3b are closed and the operating metal fitting 12 comes close to the closed end where it comes into contact with the safety tissue 9, the microswitch 13 is activated and the normally open contact 13a is closed.
is closed, a circuit of P-13a-14-N is formed and the closed end detection relay 14 is energized, and the normally open contact 14a is closed, so the operating metal fitting 12 pushes the safety tissue 9 and the micro switch 10 Even if the normally closed contact 10a opens due to activation,
Since the door reversal command relay 15 is not deenergized by the circuit P-8a-14a-15-N, the car doors 3a, 3b can be completely closed without the door reversing circuit 16 operating.
