PURPOSE:To keep off any service decline due to a misuse of the call registration of an elevator for the disabled, of general users by installing a timer device which operates a call registering relay of an elevator for the disabled when a special call button for the disabled elevator is operated longer than an ordinary call button. CONSTITUTION:A call registering relay 2 operating in response to the call when general users operate an ordinary call button 1, and another call registering relay 6 for an disable elevator operating in response to the call when a user who requires the disable elevator operates a special call button 4 as far as the longer specified time than the ordinary call button 1 and its timer device 5 are all installed in an interval between both d.c. power terminals P and N. In this constitution, when the special call button 4 is continued to operate longer than operating time required for operation of the ordinary call button 1, the timer device 5 operates and thereby the call registering relay 6 of the disable elevator is energized, so the elevator is made so as to be summoned to the elevator hall. With this constitution, useless operation of the disable elevator at time of operating the special call button 4 by misoperation or the like is thus preventable. |
