PROBLEM TO BE SOLVED: To provide a camera for highly accurately performing motor driving control in combination with the latest micro controller, and configuring a motor driver circuit without errors to fluctuation of power supply voltages easily at low cost. SOLUTION: A motor control circuit 12 having an input terminal for inputting a constant voltage output from a D/A conversion circuit and controlling the rotation of a motor at a constant voltage depending on the output voltage from the D/A conversion circuit has a first transistor Q1 to normally rotate a motor 8, a second transistor Q3 to reversely rotate the motor 8, and a motor driver IC 19 sharing the constant voltage input terminals of the first and the second transistors Q1, Q3 to rotate the motor 8.
