摘要： A system for indicating photographic information which includes a circuit for converting an optical signal into an electrical signal. Comparing elements are provided for comparing the electrical signal with one of a plurality of reference signals having different levels, and electrical elements serve to produce an indication signal responsive to the output from one of the comparing elements. A plurality of luminescent components are connected to the signal producing element for turning-on in response to an indication signal. A plurality of indicating segments indicate the photographic information which the luminescent elements irradiate, the number of indicating segments being less than the number of luminescent elements and at least one of the indicating elements is selectively illuminated by more than one of the luminescent elements. The indicating segments have different colors to indicate different kinds of photographic information, whereby one indicating segment is capable of indicating two different modes of operation of the system. This is a continuation of application Ser. No. 437,621 filed Jan. 29, 1974, now abandoned.

摘要： A camera of the type in which the shutter actuator is operated by means of an electromagnet or a permanent magnet associated with a solenoid has a film winding mechanism and a shutter tensioning mechanism operatively connected with each other through an improved interconnecting mechanism which includes a cam arrangement and a switching arrangement for the electromagnet or the solenoid. The cam arrangement is constructed as having complementary camming surfaces to facilitate the minimization of dimensions of the interconnecting mechanism. During the film winding or shutter tensioning operation, the electromagnet or the solenoid is rendered inoperative or operative respectively by the switching arrangement to thereby reduce the torque of a single operating member for the film winding and shutter tensioning mechanisms.

摘要： The present invention relates to an exposure information setting device for a camera having a digital control system in which the aperture value of the lens is applied to the exposure amount control circuit as digital information by means of the aperture value setting mechanism. The device is so designed that the first comb tooth shaped conductor pattern and the second comb tooth shaped conductor pattern are arranged in parallel with each other in such a manner that a phase difference takes place between them. A pair of series of pulses are obtained by making the contact in functional engagement with the aperture value setting operation, moving slidingly over the first and the second conductor patterns. The direction along which the aperture value information varies is detectable by applying the pair of series of pulses thus obtained to the exposure operational circuit through the phase sorting circuit.
摘要翻译：本发明涉及一种具有数字控制系统的相机的曝光信息设定装置，其中通过光圈值设定机构将透镜的光圈值作为数字信息施加到曝光量控制电路。该装置被设计成使得第一梳齿形导体图案和第二梳齿形导体图案彼此平行地布置，使得它们之间发生相位差。通过使接触与孔径值设定操作功能接合而获得一对脉冲序列，滑动地移动到第一和第二导体图案上。孔径值信息变化的方向可以通过将这样获得的一对脉冲序列通过相位分类电路施加到曝光操作电路来检测。
