MIRROR DEVICE

PURPOSE:To control a mirror easily to its previously stored position, by providing a variable resistor, changing its resistance value in accordance with a position of the mirror, applying a pulse to an integrating circuit, connected to said variable resistor, and measuring a time till waveform of the pulse reaches a specified value. CONSTITUTION:Position setting of mirrors 1, 2 are performed by controlling right and left selector switches 16, 17 are reversible drive switch 12 or 15, applying a signal to a motor reversible driver circuit 22 through a control memory circuit 20 and rotating driving motors 7, 8. At this time, variable resistors 9, 10 are provided with a proper resistance value in accordance with the set position. After operation of a memory switch 18, a position selector switch 19 is controlled to apply a pulse signal from a memory circuit 20 to a measuring circuit 26 including an integrating circuit, and the circuit 26 measures the before said resistance values to store in the memory circuit 20. One of the position selector switches 19 is controlled to allow motors 8, 9 by each circuit 20, 26 to control the mirror to its stored position, then reproduction of the stored position of the mirror is performed.
