PURPOSE:To realize a compact controller of a camera and at the same time to attain an application of the controller to an ordinary shutter by means of the common use of the members, by securing the following action of both a focus controlling member and an exposure value controlling member to the front traveling member which travels at a certain speed prior to shutter release. CONSTITUTION:A release lever 2 turns with push of a shutter button, and a front traveling panel 4 starts traveling to the left at a prescribed speed that is reduced by a speed controlling part 7. With this shift of the panel 4, a mirror driving lever 26 and a focusing control ring 28 turn. Then an electromagnet 32 is demagnetized to stop the turning of the ring 28 when coincidence is obtained for the photodetecting outputs obtained via a fixed mirror 18 and a mobile mirror 22. At the same time, a photodetecting diaphragm plate 34 turns in accordance with the shift of the panel 4. Then the turning of the plate 34 stops with the demagnetization of an electromagnet 38 when the light volume received at a photodetector 44 reaches a prescribed level. The panel 4 moves more to turn a driving plate hooking lever 52, and a shutter driving plate 50 starts traveling. |
