PURPOSE: To simplify the control when the continuous snapshot is executed for several seconds or less and to reduce the power consumption, by revolving a motor for a fixed period after the recording is over.
CONSTITUTION: When a shutter 10 is pushed, a motor 5 is revolved by a motor control circuit 12. An optical shutter 7 is opened and closed after the number of revolutions of the motor 5 reaches a specified level. Then the photoelectric conversion is carried out by an image pickup element 8. The signal of the element 8 is read out, and the signals equivalent to a frame are sampled to be recorded to a magnetic head 4. In such a way, the shutter 7 is opened and closed after the number of revolutions of the motor 5 reaches a fixed level. This produces a delay of about one second for the first image. However it is possible to release the shutter without producing virtually any delay in case of the continuous snapshot by revolving the motor 5 for a specified period after the recording is over.
