いときがある。As is well known, there are three types of contacts for switches and relays. One is a method in which the contacts are closed and conductive when the knob is pressed or excited, and this contact is referred to as an a contact (or a normally open contact because it is normally open). The second is a method in which the contact is normally opened and the contact is opened and becomes non-conductive when the knob is pressed or excited, and this contact is called a b-contact (normally closed contact because it is normally closed). . The third is a c-contact having both a-contacts and b-contacts. The c-contacts may not be connected to any contacts during switching.

作中の扉は戸開動作に転換される。When a passenger or the like comes into contact with the door 2 during the door closing operation, the movable element 3 is pushed and moves inside the door 2. By this operation, the switch 4 and the switch 5 are pushed and their a contacts 4a and 5a are closed, so that the door safety device relay 6 and the door safety device relay 7 connected in series are excited, and the respective relays 6, 7 A contacts 6a and 7a are closed. When the a contacts 6a and 7a of the door safety device relays 6 and 7 are closed, the door opening relay 8 is excited and operates.
This operation signal is sent to a door driving device (not shown), and the door during the door closing operation is converted to the door opening operation.

Since the contact 4a is not closed, the relay 6 for the door safety device is not excited, and the a contact 6a of the relay 6 for the door safety device is opened. However, if the other switch 5 is normal, the a-contact 5a is closed and the door safety device relay 7 is normally excited, and the a-contact 7a is closed. , And a door opening signal is transmitted to a door driving device (not shown), whereby the door 2 can be reliably switched from the door closing operation to the door opening operation. If the door safety device relay 6 is not excited due to the malfunction of one of the switches 4, the b
The contact 6b2 is closed. The other normal operation switch 5 excites the door safety device relay 7 and opens its b contact 7b2. However, the door opening relay 8 is excited through the a contact 7a of the door safety device relay 7. Therefore, the switch abnormality detection relay 10 is excited by the closed a contact 8a to operate.

Then, an abnormal state signal is transmitted together with the identification number of the elevator and the like, so that the abnormal state can be grasped at a remote place.
