PURPOSE: To eliminate a signal cable by interposing a transceiver to carry out photo-transmission between an arrival predicting lamp and an elevator hall wall surface, also providing a transceiver to carry out photo-transmission on a temporarily set hall button to be set in a hall and transmitting and receiving a signal at 1:N between the arrival predicting lamp and the temporarily set hall button. CONSTITUTION: When a rising call button 5 is pressed, a signal is input to a control part 10. The input signal is encoded at an encoding part 12, and light is transmitted from a projector-receiver 14 through a transceiver 13. A projector-receiver 19 receives light from the projector-receiver 14, doubles it in signs at an encoding part 17 and outputs a sign to a control part 16. This output is input to a control panel 20 through the control part 16, and necessary control is carried out as an elevator. A part of the rising call signal input to the control panel 20 is answered back to a temporarily set hall button 4 and lights a rising call registration lamp 6. When the elevator reaches a rising call stage floor, the lamp is put out by a reset signal of a rising lamp from the control panel 20. |
