Abstract

PURPOSE:To facilitate ''swing'' photography by providing and operating a lens shutter operating mechanism and a mirror opening and closing motor independently of each other. CONSTITUTION:With a release switch 27 pressed down, a shutter 15 is closed fully, a diaphragm 13 is stopped down, and a mirror is lifted up. When the elevation of a light shielding plate turns on a mirror upper-limit switch 42, the shutter is opened, and then closed after a time determined by an exposure time control circuit 46, and the mirror is set down to turn on a mirror lower- limit switch 49, thereby opening the diaphragm and shutter fully. Simultaneously, a film is advanced by the output of a control circuit 46. During preview photography, a preview switch 56 is turned on to turn off a diaphragm driving circuit 14, so that the diaphragm is neither opened nor closed. During mirror-up photography, a mirror-up switch 32 is turned on to set the mirror and light shielding plate up, and mirror-down operation is not performed.
