<p>PURPOSE:To prevent careless or erroneous operation, by using operation instructing signals for moving headlights up and down and positional signals as control signals so that a motor drive instruction is delivered in association with the turning of the operation instructing signal. CONSTITUTION:A retractable headlight drive control device provided with a motor mechanism including a motor for moving headlights up and down, comprises operation instructing signal forming means 11, 12 for forming operation instructing signals composed of a elevation and lowering instructing signals U, D for raising and lowering the head lights, and positional signal generating means 21, 22 operated in synchronization with the motor mechanism, for generating positional signals composed of raised and lowered position indicating signals in accordance with the positions of the headlights. Further, motor drive instruction signal forming means 31, 32 deliver a motor drive instruction signal MD to the motor mechanism through a NAND gate 3 only when the operation instructing signals are turned into the lowering instructing signal from the elevation instructing signal, or viceversa.</p> |
