PROBLEM TO BE SOLVED: To carry out a wheelchair call and a general call by one push button switch and automatically judge and register the wheelchair call and the general call by automatically detecting the arrival of a wheelchair utilizer and registering as a wheelchair exculusive call automatically when an utilizer call button is operated. SOLUTION: When a general utilizer arrives at an elevator hall and pushes a hall call button 3, a circuit of P-hall call button 3-wheelchair detection relay- contact point 2b-general call circuit 4-N is made and the same operation that an usual general hall push button is pushed is made. When the wheelchair utilizer arrives at the elevator hall, a wheelchair detection relay 2 is operated by the wheelchair detection sensor 1. When the hall call button 3 is pushed under this state, the circuit of P-hall call button 3-wheelchair detection relay- contact point 2a-wheelchair call circuit 5-N is made and the same operation that the wheelchair exclusive push button is pushed is made. The wheelchair call and general call are carried out by one push button switch and the wheelchair call and general call are judged and registered, automatically. |
