摘要： An exposure control apparatus operating with selection of the diaphragm preselection and shutter preselection automatic exposure control modes is provided with first and second signal shapers arranged to cooperate with a lens aperture mechanism through a common intermediate member. Upon setting of a desired diaphragm value in the lens aperture mechanism, the intermediate member is driven along with the first signal shaper in exactly corresponding relation. In the shutter preselection automatic diaphragm control mode, while the first signal shaper is cut off from connection with an exposure value computer, the second signal shaper is driven for scanning operation to produce ever-varying outputs which are compared with the output of the computer upon coincidence to stop movement of the lens aperture mechanism, thereby the scanning result is translated to the proper diaphragm presetting, as the intermediate member is arranged to delay the start of movement of the lens aperture mechanism from the start of the scanning operation by a time interval determined by taking into account the signal response characteristics of the automatic diaphragm adjusting mechanism.

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： The present invention relates to a camera so designed that the aperture preset mechanism as well as the aperture adjusting mechanism at the side of the camera body are operative by means of the first urging mechanism provided in the lens barrel. The aperture adjusting mechanism is operated by means of the release operation of the camera so as to close the aperture preset mechanism down to a certain determined aperture value. Between the aperture adjusting mechanism and the aperture preset mechanism an intermediary member and the second urging mechanism are provided. By means of operating the focus depth confirmation member, the aperture preset mechanism is closed down to a certain determined aperture value through the intermediary member. The camera is brought into the state ready for taking a picture by means of the second urging mechanism upon releasing the focus depth confirmation operation.

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.
