Abstract
PURPOSE: To prevent buttons in a gondola except for a door opening button, an information button, etc. from functioning even if the former buttons are pressed when an illumination lamp is off, a motor generator is stopped and the door of the gondola is closed.
CONSTITUTION: When the gondola is stopped at a floor and the door is closed and the motor generator is stopped, a door open/close state signal 13 is at logic "L" and a motor generator state signal 14 is at logic "H" so that an AND gate 18 is opened. Since the output of an inverter gate 17 is at logic "L" and the output of an OR gate 16 is also logic "L", AND gate 19W28 are closed. Whichever button in the gondola is pressed at that time, one of button signals 1aW12a becomes "H" and passes through an OR gate 15 so that the output 18a of the AND gate 18 becomes "H". The output 18a is applied as a door opening instruction to a control unit to open the door.
