Abstract: A photographic camera is provided with a zoom lens having a front lens group which is moved back and forth in the direction of an optical axis held by a movable lens barrel and a rear lens group which is disposed behind the front lens group and is moved backed and forth in the direction of the optical axis maintaining a predetermined optical position relative to the front lens group in response to movement of the front lens group. A lens drive mechanism includes a cam lever which is supported on the camera body for rotation about a rotational axis perpendicular to the optical axis. A first cam pin is provided on the movable lens barrel and a first cam hole is provided in the cam lever. A second cam pin is formed integrally with the rear lens group and a second cam hole is provided in the cam lever. A predetermined play for permitting focusing of the zoom lens is formed between the first cam pin and the first cam hole in the direction of movement of the movable lens barrel.

Abstract: A photographic camera has a cartridge chamber in which is loaded a film cartridge having a roll film entirely rolled to its leading end around a spool in a cartridge body and a light-shielding shutter member for opening and shutting a film exit slit formed in the cartridge body, an entrance opening to the cartridge chamber, and a chamber lid which is mounted on the camera to be moved between an opening position where it opens the entrance opening and a closed position where it closes the entrance opening. A shutter lock member moves to a shutter locking position, where it prevents release of the shutter of the camera, in response to operation of a rewind button. A holding member holds the shutter lock member in the shutter locking position, and a release member causes the holding member to release the shutter lock member after closure of the light-shielding shutter member of the film cartridge in response to opening of the chamber lid.

Abstract: In communication equipment which uses a battery as the power supply, when a controller increases the transmission power at a transmitter corresponding to a drop in the electric field intensity, the controller lowers, accompanying that operation, a reference voltage from a reference voltage source which is used for comparison with the battery voltage for the purpose of detecting a drop in the battery capacity. Therefore, even when the battery voltage is dropped due to an increase in the transmission output, the reference voltage is also lowered correspondingly, so that there will not occur an erroneous detection of drop in the battery capacity due to the drop in the battery voltage.

Abstract translation: 在使用电池作为电源的通信设备中，当控制器增加对应于电场强度下降的发射机的发射功率时，控制器随着该操作降低来自参考电压源的参考电压 用于与电池电压进行比较，以检测电池容量的下降。 因此，即使当由于传输输出的增加而导致电池电压下降时，参考电压也相应降低，从而不会由于电池电压的下降而发生电池容量下降的错误检测。

Abstract: An automatic rewinding camera wherein an automatic advance of the photographic film by one frame is caused by shutter release operation and rewinding of the photographic film is automatically started when the film is prevented from further advance. The camera has a film-driven sprocket wheel, by the rotation of which film movement signals are produced. A timer circuit maintains, during the passage of a predetermined active time which is shorter than the time required to advance the photographic film by one frame, the camera motor in forward rotation so as to advance the photographic film. The timer circuit is reset by the film movement signals. But when those film signals stop, that is, when the film is fully extended from the cartridge, then the timer is not reset; and the measurement of the full predetermined active time, by the timer, without resetting, results in the motor being reversed to rewind the film.
