PROBLEM TO BE SOLVED: To extend an open time of a door, by making a state of an elevator, an operating order and a number of operations of operating buttons act as conditions for an open mode extension command. SOLUTION: When only an open button 1 on an operating panel in a cage is actuated, it simply functions as an open button, and when the open button 1 on the operating panel is actuated, and while it is actuated, registration buttons 2a, 2b for calling for a cage are actuated, it functions as open mode extension command button. Open mode extension relays 6a, 6b are actuated by throwing a normally-open contact 4a of a condition switching relay 3, and the open button 1 on the operating panel in the cage and the registration buttons 2a, 2b for calling for a cage function as an open mode extension command buttons. When an open mode extension circuit 9 is actuated, an open mode is extended for an optional time by setting an open mode extension time for every registration button for calling a cage. The open mode extension time can be optionally set by a ROM. |
