PURPOSE:To give many advantageous functions, by using one electromagnet as one control center for operating various mechanisms which execute various operation modes in an automatic focusing camera. CONSTITUTION:A shutter release device consists of a release operating member 1, a releasing member 2, an electromagnet 3, a shutter detaining member 3, a focusing detention member 5, a focusing operation member 6, a shutter operating member 10, etc. In this case, one electromagnet 3 is used as a control center for the purpose of operating various mechanism form various operation modes in an automatic focusing camera. Consequently, in this invention, the framing change photography and the self-timer photography are possible with a simple device, and the release lock is performed when the power source battery is wasted, and thus, many advantageous functions are given to the automatic focusing camera. |
