Abstract

PURPOSE:To make the frame speed high as much as possible at a continuous photography time, by starting the advancing charge operation by a shutter closing completion signal and starting the auto-focus operation by a return completion signal of an observing mirror. CONSTITUTION:An electric advancing device 20 by which the continuous photographic operation is possible, a detecting circuit which detects the closing completion of a shutter 16 to output a shutter closing completion signal, and a circuit which outputs a mirror return completion signal on a basis of the return of an observing mirror 9 are provided. The advancing device 20 is started on a basis of the shutter closing completion signal before a range finding means is started on a basis of the mirror return completion signal.
