摘要： In a camera having an LCD and a clock device, a power source consists of a battery and a booster circuit. When a power switch button is pressed, the camera moves to an ON mode including a drive mode and a standby mode. In the drive mode, the booster circuit is continuously turned on to supply voltage of a predetermined high level. In the standby mode, the booster circuit is intermittently turned on to output voltage of between the predetermined high level and a minimum display voltage level that is necessary for the LCD to keep its display density in a proper range. The booster circuit is normally turned off in an OFF mode. But if the battery voltage goes below a reset level below which a clock device of the camera cannot work, the booster circuit is intermittently turned on in the OFF mode, to boost the battery voltage up above the reset level and drive the clock device by the output voltage of the booster circuit.

摘要： A preparatory winding type camera wherein one frame is rewound after the whole film in the patrone is previously wound up, and thereafter, the film is automatically rewound into a patrone frame after frame each time a shutter release is performed. During the winding of the film at the time of the preparatory winding processing, a central processing unit causes a liquid crystal display device (LCD) to display the number of film frames always smaller one frame than the normal display, and, when one frame is rewound after the whole film in the patrone is wound up, the number of film frames currently displayed on the LCD is maintained as it is. With this arrangement, the number of film frames displayed on the LCD can avoid the up-down fluctuations during the preparatory winding processing.
摘要翻译：预备卷绕式照相机，其中一个框架在卷笔之后的整个胶片预先卷起之后被重新卷绕，此后，每次执行快门释放时，胶片都自动地重新卷成帧后的图像框。在预备卷绕处理期间的卷绕期间，中央处理单元使液晶显示装置（LCD）显示总是比正常显示更小一帧的胶片帧的数量，并且当一帧为在电影中的整个电影被卷起后重新卷绕，目前显示在LCD上的电影帧的数量一直保持不变。通过这种布置，LCD上显示的胶片帧的数量可以避免在预备卷绕处理期间的上下波动。

摘要： A zoom lens is zoomed selectively in either of two opposite directions by a motor which is rotated by a driver. First and second zoom switches cause the zoom lens to move at a higher speed. Third and fourth zoom switches cause the zoom lens to move at a lower speed for precisely stopping the zoom lens. A CPU connected to the four switches controls a zoom motor to rotate selectively at higher and lower speeds. The first and third zoom switches cause the zoom lens to move in the direction of telephotography, while the second and fourth zoom switches cause the zoom lens to move in the direction of wide-angle photography. In order to keep the speed of the zoom lens unchanged despite the difference in its direction, an electric current of a larger electric power is applied to the motor for rotation in the direction that requires more work.

摘要： A battery operated camera having a zoom lens in which film advance is controlled by counting pulse signals generated by film perforations and a first film frame is automatically placed in an exposure aperture when the film is loaded. The camera is set to an initial operation mode upon the battery being replaced. The initial operation mode is cleared in cooperation with shutter release when the camera is in the initial operation mode, so as to avoid an advance of several frames upon replacing the batter. A switch is provided in association with the lens barrier, and conditions of the switch are read upon replacing the battery so as to retract the zoom lens when a switch condition indicating that the lens barrier is closed is read or to extend the zoom lens when a switch condition indicating that the lens barrier is open is read. A data recording unit is provided and consists of liquid crystal segments for forming digits to be recorded, the liquid crystal segments being controlled to make all the segments visible for a predetermined time period upon loading of a new battery.
