    • PURPOSE:To make it possible to align floors with each other even in a range in which a floor misalignment detecting device is not actuated, by providing such an arrangement that when waiting for a predetermined time is detected, a cage is lowered to a position in such a range that the floor misalignment detecting device is actuated by force. CONSTITUTION:When a cage is at a position in a range in which a floor misalignment detecting switch is not actuated, since a contact B2 is closed, if a contact H2 is closed in association with a turn-on of an up button 1U in an elevator hall on the first story, a downward inching operation relay D is turned on so as to close its contact D2. As a result, an downward inching compensating device S2 is actuated, so as to run the cage downward. When the cage is lowered to a position in a range in which the floor misalignment detecting switch is actuated, the switch is actuated, resulting in energization of a floor misalignment detecting relay B, and accordingly, a contact B2 is closed while the contact B2 is opened. Further, the downward inching operation relay D is turned off while the downward inching compensating device S2 comes to a stop once, or a floor aligning operation relay U is turned on while an upward inching compensating device S1 is actuated, thereby the upward floor aligning operation is carried out.
