摘要： A photographic camera having an automatic rangefinder system wherein a light emitter projects a beam of light through a convergent lens to illuminate a target object. This beam of light is detected through another convergent lens by one of a group of photoresponsive elements forming a light receiver. Depending upon which photoresponsive element of the light receiver detects the reflected beam of light, the range of the target object to be photographed from the photographic camera is indicated. The light emitter and the light receiver are supported by a single support member in laterally offset relation to each other and the lens elements for converging the projected beam of light and the reflected beam of light, respectively, are integrally formed of a synthetic resin. The rangefinder elements are assembled into a rangefinder module.

摘要： A mechanism for determining the focus by an objective lens of an image on a focal plane includes a needle shaped or other narrow scanning mask transversely oscillated in the focal plane between the lens and a transversely extending photoelectric element exposed to the mask intercepted image. The output of the photosensitive element is coupled by way of a high pass filter or differentiating circuit and a rectifier to a meter, the maximum meter reading indicating maximum AC output and hence maximum focus. The output of the photosensitive element is also connected through a low-pass filter to a meter or exposed control mechanism.

摘要： A light measuring circuit for an exposure time control device uses a photodiode to measure the object brightness and a logarithmic compressing diode to provide negative feedback between the output terminal and one input terminal of a differential amplifying circuit. The output of the light measuring circuit is summed with signals representing film sensitivity and diaphragm aperture setting and the resulting exposure time control signal is compensated for changes in temperature. An antilogarithmic converting circuit generates a signal proportional to the logarithmic value of the compensated exposure time control signal. The antilogarithmic converting circuit operates at the same reference potential as the differential amplifying circuit and its output is integrated and then used to terminate exposure.

摘要： A distance measuring device includes light emitting diode for emitting light toward a subject to be photographed, and a pair of light receiving elements spaced by a predetermined base length from the light receiving diode. The light receiving elements are position side-by-side such that the boundary therebetween extends in a direction which is perpendicular to the direction of the base length so that an image formed by the light emitted to, and reflected from, the subject, will be formed on the light receiving elements in a bridged manner. The respective areas on the light receiving elements occupied by the image differ relative to the distance to the subject. A ratio between the signal levels obtained from the light receiving elements is calculated as a signal representing the distance to the subject.

摘要： Dating information is applied to camera film from date information displaying circuitry which receives decoded electronic time signals generated by a chronometer. A first power source energizes the chronometer and a second power source energizes the decoder and display circuitry and other components such as the exposure control circuit. A monitor is provided to enable the camera operator to observe the date information. Manually operable switches are provided to independently actuate the dating apparatus and the exposure control circuit as well as to independently operate the display circuitry and the monitor.In a modified embodiment, logic and switching circuitry are provided to monitor and date either exposure data obtained from a light measuring circuit and analog/digital converter or the date information generated by the chronometer. A manually independently operable switch for actuating the display circuitry is ganged with the switching circuit to expose the date information on the film. Another switch ganged with the switching circuit enables the date information to be monitored.The display circuitry includes switches enabling the date information to be monitored independently of dating the film. One switch is actuated in timed relation with the shutter operation and manual closure of a second switch and opening of a third switch effects dating of the camera film.

摘要： A photoelectric focus detecting member includes a semiconductor substrate of a first polarity and at least two closely transversely spaced parallel longitudinally extending photosensitive laminae of a polarity opposite to the first polarity to form corresponding photodiodes. Each of the photosensitive laminae is masked to provide regularly spaced light receiving areas alternating with masked areas, the light receiving areas of successive transversely spaced photodiodes being relatively longitudinally offset to present a checkered pattern. The detecting element is positioned in the focal plane of a lens and is either stationary or oscillated. The difference in potential between the diodes or the amplitude of the AC current in a circuit including the photodiodes is a function of the condition of focus of the lens.
