  "textContent": "The present invention provides a mirror device motor control circuit that can reliably stop a mirror at predetermined positions with a simple configuration. In the control circuit of the invention, part of a lock current flowing to the motor flows to a base terminal of a transistor. Thus, as long as a voltage corresponding to the lock current is equal to or greater than a specific value, this voltage is applied to the base terminal of the transistor, whereby between a collector terminal and an emitter terminal becomes conductive, and the current flowing to a gate of a MOSFET is grounded via the collector terminal and the emitter terminal of the transistor. For this reason, when the lock current flows, conduction between a drain terminal and a base terminal of the MOSFET is released and a drive current of the motor is cut off.",
