<p>PURPOSE:To provide the device of simple and rational constitution by controlling each of focusing and shutter operation by means of a single electromagnetic operation device. CONSTITUTION:The operation of one electromagnet 39 is controlled by a focus detection controlling circuit F and an exposure controlling circuit S. When current flows to the coil L of this electromagnet 39, an iron piece 2a is attracted so that an iron piece lever 2 is turned right. This electromagnet 39 operates as an electromagnetic operation device, and a means of carrying out the controlling of this electromagnetic operation device by the focusing detection controlling circuit F and the exposure controlling circuit S separately in time to the 1st time zone and the 2nd time zone is provided. The electromagnetic operation device is so arranged as to control the operation of the focusing mechanism in the 1st time zone and the opening-closing operation mechanism of the shutter in the 2nd time zone.</p> |
