Abstract
Disclosed is an electric apparatus comprising a housing with a door, a turntable arranged in the housing for rotating an object, a synchronous motor for driving the turntable, and a control portion for controllling the driving of the synchronous motor, the control portion having apparatus for storing the time required for the turntable to rotate once, apparatus for determining whether or not a time period which is approximately a natural number multiple of the time required for the turntable to rotate once, has elapsed since initiation of turntable rotation, and apparatus for stopping an operation for the rotation of the turntable on the basis of the determination that time, which is approximately a natural number multiple of the time required for one rotation of the turntable, has elapsed. When the synchronous motor is energized during only the time which is approximately a natural number multiple of the time required for the turntable to rotate once, the turntable stops after it rotates approximately a natural number of times. Accordingly, the object placed on the turntable is stopped in the same position within the housing as that at the time when the rotation of the turntable was initiated, so that the object can be easily taken out.
