摘要： An auto-focus camera including an automatic rangefinder device for generating a distance signal indicative of the distance between the camera and a target object to be photographed, a timer circuit for generating an output signal a predetermined time after a power switch is closed, to place a lens drive mechanism in an operative condition for repositioning an objective lens assembly of the camera in search of the true focus setting, and a lens arresting circuit including electromagnetic units. Either of the electromagnetic units is operable to arrest the objective lens assembly at a corresponding focal position when energized by the distance signal. The automatic rangefinder device can measure the distance from the camera to the target object independent of the release of the lens drive mechanism.

摘要： A small single lens reflex camera for use with a 110 film format cartridge is provided. The size of the camera body can be maintained at a minimum by an improved view finder optical system which coacts with a movable mirror movable into and out of the photographic path in correlation with the releasing operation of a shutter. A series of reflecting mirrors are utilized in the viewfinder assembly within certain angular design parameters to maintain a compact shape while permitting a highly accurate focusing system. The viewfinder optical system can be assembled as a relatively stationary sealed module unit. The movable mirror is adjustable relative to the optical path to optimize its alignment and calibration focusing of an image on the focusing plate of the module viewfinder.

摘要： A photoflash photography system includes a camera separably housing individual film cartridges carrying indicia, physical or electrical, representing the sensitivity of the film contained in the respective cartridge. A photoflash unit is coupled to the camera and has a light output which automatically varies inversely with the film sensitivity in response to the sensitivity indicia. The light output is varied by varying the charge voltage on the flash tube storage capacitor or the capacitor capacitance value. The electrical indicia may be resistors of different values and the physical indicia may be recesses of different depths or differently disposed shoulders or fingers which are detected by movable sensing members.

摘要： An electronic photoflash device includes a high voltage DC generator, a main storage capacitor and a reflector backed photoflash tube unit mounted on an insulating substrate on which are printed a high voltage conductor line connecting first terminals of the generator, capacitor and tube and a ground conductor line connecting their opposite terminals. The ground line surrounds and is proximate the high-voltage line so that the deposition of water on the substrate extends between and short-circuits the lines to discharge the high-voltage and eliminates the risk of an electric shock to the device operator. Alternative arrangements may be provided for surrounding the high-voltage conductor with the ground conductor, the conductors having proximate bare portions bridged by a surface which, when moistened, short circuits the conductors.

摘要： In a shutter release device adapted for use with a photograpic camera, especially of the compact or miniature type, delay means are selectively actuated in accordance with a set or anticipated shutter speed for delaying or retarding the initiation of actual shutter opening. The shutter opening is commenced after a lapse of time from the manual operation of the shutter release button to the operation of the shutter release member, when the scene brightness is so low that a blurred picture is anticipated. The shutter is actuated immediately after operation of the release member when the scene brightness is high enough. The delay means may be a mechanical governor of an electric delay circuit responsive to shutter speed setting or detection of scene brightness.

摘要： An auto-focus camera includes a first signal circuit for generating a first control signal only when the battery voltage exceeds a minimum permissible level for normal operation of an electric range finder and an exposure control circuit, and a second signal circuit for generating a second control signal only when the range finder has reached a stable operating state after commencement of electric power supply thereto. The existence of both the first and second control signals enables an electromagnet provided in an exposure control circuit for arresting the camera shutter in an open state to hold an engaging member out of the locus of movement of a corresponding engaging member provided on a trigger member. The trigger member can be manipulated to a terminal position for allowing operation of a focus adjusting device unless the engaging members engage one another, and the range finder is supplied with electric power from the battery during the course of the manipulation of the trigger member. The camera shutter is opened in response to the termination of the automatic focus adjustment.

摘要： A camera employing an automatic focusing system has a movable objective lens which is automatically moved from an initial position to a properly focused position in accordance with a distance signal indicative of the distance between the camera and a target object to be photographed from a distance measuring element. The automatic focusing system includes a discriminator which discriminates whether the distance measuring element properly produces the distance signal or fails to produce such distance signal. The objective lens is moved only when the distance signal is properly produced or when a substitute signal is forcibly produced from a manual control unit for the substitution of the distance signal.

摘要： A single lens reflex camera in which the drive force for returning a diaphragm to its open aperture position upon termination of an exposure operation is isolated from the force causing the return of a reflecting mirror from its picture taking position to its viewing position. The camera has a diaphragm which is normally biased in a direction for being stopped-down to a pre-adjusted diaphragm aperture. A spring mechanism when coupled to the diaphragm biases it in its open position against its normal tendency. A diaphragm drive mechanism enables the diaphragm, however, to be stopped down from its open position to its pre-adjusted diaphragm aperture upon actuation of an exposure operation. Upon completion of the exposure operation, the diaphragm drive member is disengaged from the diaphragm thereby enabling the diaphragm to return to its open aperture position under the influence of the spring mechanism. The reflecting mirror is movable from its viewing position to its picture taking position in association with the operation of the diaphragm drive mechanism and subsequently returns to its picture taking position upon termination of the exposure operation.

摘要： A motor driven film wind-up and rewind device for cameras is automatically switched from a film wind-up mode to a film rewind mode when the entire length of an unexposed film has been wound on a film take-up spool and surely remains in the film rewind mode thereafter. For the automatic switching of the modes a circuit detects increase in a motor current which occurs with a motor forced to stop after completion of the film wind-up. A movable member which is in the form of an through axle extending through a film rewinding sprocket moves from a first position to a second position immediately after initiation of the motor rotation for the film rewind, switching a switch to a state maintaining the device in the film rewind mode as well as connecting the sprocket with the motor. The movable member is returned to the first position in response to insertion of a film cartridge into a cartridge chamber of the camera and restrained at the first position till the initiation of the film rewind. With no cartridge inserted in the cartridge chamber the movable member is not returned to the first position so that the device remains in the film rewind mode allowing a camera exposure operation.
摘要翻译：当未曝光胶片的整个长度已卷绕在胶卷卷轴上时，用于照相机的电动机驱动膜卷绕和倒带装置自动从胶片卷绕模式切换到胶卷倒带模式，并且确实保留在之后的电影快退模式。对于模式的自动切换，电路检测到电机电流的增加，电动机电流在膜结束完成之后强制停止时发生。通过延伸穿过胶片倒带链轮的贯穿轴形式的可动件在电动机旋转开始之后立即从第一位置移动到第二位置，以便将电路切换到保持装置的状态回卷模式以及将链轮与电机连接起来。响应于将胶片暗盒插入照相机的暗盒腔并将其限制在第一位置，直到胶卷重新开始，可动件返回到第一位置。由于没有墨盒插入墨盒室，所以可移动部件不返回到第一位置，使得该装置保持在回卷模式中，允许照相机曝光操作。
