PURPOSE:To make a child who can not reach his hand to a register button for his destination floor possible to go to a desired floor by providing a detecting circuit actuating at no work of a second photoelectric device when a first and a second photoelectric devices are actuated, and constituting the device so as to register the destination floor previously selected when the operating direction of a cage is decided and the detecting circuit is actuated. CONSTITUTION:A first photoelectric device constituted out of a light projector 36 and a light receiver 37 so that the transverse beam of light 36a at the entrance 32 of a cage 31 is lower than nationwide mean height of school children of lower class, and a second photoelectric device constituted out of a light projector 34 and a light receiver 35 so that the transverse beam of light 34a is positioned sufficiently higher than the former one, are provided. This device is constituted out of a detecting circuit actuating at no work of the second photoelectric device when the first and the second photoelectric devices are actuated, and a destination floor register means to register a previously selected destination floor against the operating direction of the cage 31, when the operating direction is decided and the detecting circuit is actuated. |
