Abstract
PURPOSE: To perform a highly reliable control of an automobile room light, by providing a control computer, enabling the computer to accept interruptions with a predetermined constant interval, and when an interruption has occurred, judging whether the door is open or closed to control whether the turn-off of the room light should be delayed.
CONSTITUTION: A control computer 100 is provided to control a room light 44 and other equipments in response to an input to be fed corresponding to an output of the room light 44. The computer 100 includes a built-in timer to enable an interruption after the lapse of a preset time period. When closing a door, an input register 261 of the computer 100 is fed with a signal which changes from the "1" state to the "0" state. If a switch is in its "on" position at this time, the light 44 is turned on. When the door is closed, the register 261 receives a signal "1". Here, an output register 444 is kept in the "1" state for certain seconds and the light 44 is fed with electricity by means of a transistor 442, thus activating a light turn-off delay circuit.
