发明名称 CAMERA
摘要 PURPOSE:To improve the accuracy of preconfirmation of an exposure state at the time of flashlight photographing, by setting a camera to the same state as that for photographing with an electronic flashing device except film exposing and winding operations which are inhibited and preconfirming the exposure quantity. CONSTITUTION:When an index is set to a confirmation mode, a shutter control circuit interrupts normal shutter control and a rear-screen electromagnet 213 is controlled by a front screen control circuit. Therefore, the front screen 219 and rear screen 229 of a shutter are simultaneously run. This means that no slit width for exposure exists between the front and rear screens 219 and 229 and no film exposure takes place. When the simultaneous running of both screens 219 and 229 is completed thereafter, an X-contact switch SW5 is turned on upon the completion of the running of the rear screen 229 and a luminous tube emits light. Since a reflecting member having a reflectivity which is almost equivalent to the surface of a film is provided on the surface of the rear screen 229, whether or not the exposure quantity of a flashlight photographing time is appropriate is discriminated. In such case, however, film winding is not performed even when the photographing operation is completed.
