Abstract: The present invention relates to a camera having an automatic focusing device, particularly designed so that the shutter release operation is carried out only when the distance measuring operation is carried out properly before taking a photograph in order to avoid an out-of-focus photograph. During flash photography, the aperture value of the camera is controlled in accordance with the object distance value set by means of the automatic focusing device.

Abstract: A recording-reproducing device of information such as pictures, voices and so on, in which the used amount of the recording medium is counted. A plural number of the memory devices for memorizing the counted value of the used amount when the recording medium which has not been used is exchanged.

Abstract: In the camera disclosed, a control circuit responds to a focus detecting circuit to energize first display portions to produce a first mark representing the detected distance, and responds to a setting arrangement to energize other display portions to produce a second different mark representing a set distance. According to an embodiment, the control circuit displays a third mark when the first and second marks coincide.

Abstract: In the disclosed camera exposure control, data recording and film winding are performed sequentially and the system is protected from battery voltage drop arising from the effective increase in consumption of electrical energy necessary to make each exposure as compared with the ordinary camera, by detecting the battery level upon occurrence of a prescribed phase of the operating cycle. In one embodiment, the battery is also checked at a subsequent step of the cycle (for example, film winding operation is permitted only when the battery level is above the predetermined level). According to an embodiment of the invention, a sequence control circuit controls the photographic operation sequentially.
