Abstract: As a shutter release button is pressed down, a front end portion of a sequence drive lever moves toward the rear side and, as a result, a mirror-up lever is caused to rotate to the right by the force applied from a mirror up spring. In this state, a mirror drive end presses a mirror drive pin upward to raise a main mirror. In addition, a shutter drive end comes in contact with a shutter drive boss at a switching lever to push the shutter drive boss upward, thereby pulling the shutter blades downward. During a reset operation, the front end portion moves to the front side causing the mirror-up lever to rotate to the left. The main mirror is thus lowered. Since the switching lever is caused to rotate to the right with the force applied from a switching lever reset spring, the shutter blades are pulled upward to shield an opening.

Abstract: A single lens reflex camera includes a rotatable built-in flash unit. An optical member, such as a pentaprism, conducts light rays to an eyepiece unit. Pentaprism has a right roof surface, a left roof surface, and a third reflecting surface. Third reflecting surface enables light reflected by the roof surfaces to pass to the eyepiece unit. The built-in flash unit is rotatable between a housed position, in which a light emitting unit is housed within a camera body, and a use position, in which the light emitting unit projects from the camera body. The built-in flash unit rotates centered on a rotation axis that is parallel to a photographic optical axis, extending from the camera to a photographic object. When in the housed position, the light emitting unit is positioned along either the left or right surface of surface of the optical member.

Abstract: A photographing information setting apparatus for a camera has a capability of improving the operativity in setting photographing information by displaying all of the photographing information or a part thereof contained in a photographing information group when such a group is selected by an information group selecting device. In selecting photographing information, a photographing information group containing exposing modes, shutter speeds, and others is selected by the information group selecting device and at least two pieces of photographing information contained in this photographing information group are displayed in a display. For example, when a photographing information group regarding exposing modes is selected, the exposing modes PM, P, S, A and M are displayed in the display.
