PURPOSE:To prevent the occurrence of malfunction by equipping a means of extending a period from the ending of power feed to an electromagnetic mechamism for automatic focusing control to the start of power feed to the electromagnetic mechanism for exposure control. CONSTITUTION:It takes about >=10ms to obtain mechanical stability after a coil 2 is powered down by a focusing signal AF, by disengaging the projecting part 5b of a control lever 5 and the bent and raised part 7b of a driving plate 7 from each other, by engaging the bent part 5a of the control lever 5 with the projecting part 7d of the driving plate 7 through the movement of the driving plate 7 by the energizing force of a spring 9, and by stopping the driving plate 7. Therefore, when shutter operation starts some seconds after the completion of the operation of the AF to attract an armature again, the projecting part 7d of the driving plate 7 and the bent part 5a of the control lever 5 are disengaged from each other and the driving plate 7 starts moving to the right in the figure by the energizing force of the spring 9. |
