PURPOSE:To prevent forgetting to reset a key switch, and improve operationability by operating a reset type key switch of a specified floor of elevator halls to switch the operation to the special purpose operation, and cancelling the special purpose operation when a cage does not travel for a predetermined time after the cage arrived an objective floor. CONSTITUTION:When a special person operates a reset type key switch SW at an elevator hall of a specified floor to perform the special purpose operation, a contact point SWa is closed to energize a relay A. When a contact point Aa1 is closed, a relay 3S is energized to be maintained by itself with a contact point 3Sa2, and a display lamp SL is lighted by closing a contact point 3Sa1, and while the operation is switched to the special purpose operation, and a cage arrives a specified floor automatically. A special person rides into the cage, and goes an objective floor directly, and after the arrival, when the cage is stopped, for example, for three minutes, the special purpose operation is cancelled automatically, and the operation is reset to the ordinary operation. Forgetting to reset the key switch SW is thereby prevented, and operationability is improved. |
