Abstract: A single-lens reflex camera with a flash unit built into the camera body above the viewing pentaprism. The unit is movable from an operating position to a non-operating position, preferably enclosed in the camera body. The built-in flash unit may be automatically closed by inserting an external flash in a flash shoe. A display panel may be included on the top of the flash unit housing.

Abstract: A release device for unlocking the back-cover of a camera includes a back-cover lock member urged in a direction to lock the back-cover, an operating lever pivotally disposed along a side of the camera and operable externally of the camera so as to be angularly displaced therefrom and an interlocking plate for interlocking the operating lever with the back-cover lock member. The operating lever is engageable with the interlocking plate after the operating lever is angularly rotated through a predetermined preliminary angle in an opening direction from a position where the operating lever is disposed along the camera body so as to displace the interlocking plate and to correspondingly displace the lock member to thereby unlock the back-cover.
