摘要： A camera system is capable of operating in a number of different photographic modes and includes a display system which provides information relevant to each of the modes. The camera system also includes an automatic film rewinding mechanism that has two modes of operation. In a first, automatic, mode, the tensioning of the film during winding is detected to indicate the end of the roll of film. Upon such detection, the film is automatically and fully rewound into the film cartridge. In a second, user selectable, mode a signal is manually provided by the user to initiate film rewinding. Rewinding of the film is stopped just prior to the time the end of the film enters the cartridge, so that a portion of the film leader remains extended outside of the cartridge.

摘要： A mode selecting device for use in a camera provided with the various picture taking modes including standard picture taking mode, self-timer picture taking mode, flash light picture taking mode, close picture taking mode, fill in flash mode, nonflash mode and consecutive picture taking mode. A mode setting button is operable to select the mode and a memory is provided to store data corresponding to the selected mode. Also disclosed is a brightness measuring circuit and an automatic exposure control circuit. A flash is enabled or disabled in accordance with the mode selected and the measured brightness value. The camera is automatically reset to the most frequently used mode for emitting the flash light automatically under low light condition after a exposure has been completed, or a given time after the exposure has been completed. Additionally, a warning indicator is actuated when it is detected that the rear lid has been opened and film is mounted in the camera, and a display is provided to indicate the presence of film in the camera when a warning signal has been stored.

摘要： An electronic appliance having a microcomputer, peripheral devices controlled by the microcomputer, a main battery acting as power source, and a backup battery for outputting signals indicating the presence and absence of the main battery. Checking is made of whether the main battery is loaded in the appliance or not and whether the output voltage of the main battery is above a predetermined voltage or not. When the main battery is not loaded or when its output voltage is below the predetermined voltage, the backup battery is made available for preserving information in the memory inside or outside the microcomputer in good order, with operations of the peripheral devices being restricted at such times. Further, the disclosed electronic appliance provides for limiting malfunctioning of the microcomputer and the peripheral devices when a new main battery has been loaded in the appliance as replacement for an exhausted main battery.

摘要： For a photographic lens movable from a first position toward a second position by a shutter release action, the first position is set outside the actual focusing range of the lens from the nearest focused position to the infinity focused position to render the lens pre-movable over a specified distance from the first position to the actual focusing range. Lens position signal generating means operatively related to the movement of the lens generates an electric signal corresponding to the position to which the lens is moved. During the pre-movement of the lens, the position signal generating means emits a signal for initiating a data recording light source into operation so that the light source can be lighted for a substantially prolonged period of time.
