Abstract

PURPOSE:To drive a motor securely and to reduce the cost of a motor driving device, by detecting the movement of the movable mirror of a camera by a reed switch and by controlling the motor driving device with its output. CONSTITUTION:When a release button is pushed and a movable mirror 1 rotates from the position shown by the alternate long and short dash line to the position shown by the dotted line, since a permanent magnet 7 provided at the tip of the mirror 1 in opposition to a fixed reed switch 10 separates, the reed switch becomes nonconductive. As a result, a motor drive controller connected to lead-out lines 10a and 10b is put in operation to stop a motor. Thus, the motor is driven securely and its cost is reduced.
