    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: A photographic camera having a manually and automatically adjustable diaphragm is provided with an electromagnetically operated diaphragm scanning mechanism in combination with a manually operable depth of field pre-viewing device to enable a visual determination of the utilizable zone of sharpness in a reflex viewfinder of the camera regardless of the fact that the camera remains in the run down position. For this purpose, the diaphragm scanning mechanism includes a scanning member and a driving member arranged to establish driving connection therebetwen during the automatic adjustment of the diaphragm. Release means is provided and is responsive to the termination of closing operation of the camera shutter for effecting release of the driving connection, whereby the photographer before cocking the camera is enabled to manipulate the diaphragm followed by the pre-viewing device to read off the range of sharpness in dependence on the manual setting of the diaphragm for use in making a subsequent exposure.

    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: 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.

    摘要: The present invention refers to a system for digitally indicating the digital input information, and particularly for avoiding the flickering of the indication state of the indication means in case the input information varies. The system includes a control means for conveying the digital input information to the indication means periodically to update the content of the indication means at the end of a determined period. When input information varies excessively, it is detected and immediately conveyed to the indication means independently of the update at the end of the determined period. Accordingly, the system is quite efficient as an indication system for a continuously varying input information.

    摘要: An exposure control device is disclosed which has an extremely high accuracy as compared with the prior art, the error range being within a one-eighth step. For such a highly accurate control of exposure time, a value of exposure time to be determined is converted to a binary code of n bits, of which the lowest one bit is weighed one-eighth step. Based on the decimal number corresponding to the upper m bits of the binary code, the frequency of the control signal is adjusted and is used in reading out the lower (n-m) bits of the same binary code, whereby the period of actuation of the shutter is determined.

    摘要: An automatic exposure control apparatus for controlling the diaphragm of the camera in accordance with the preselected shutter time and the exposure value, in which a digital-to-analog converter having a counter responsive to the number of pulses supplied from a clock pulse generator through a gate produces a time variable output capable of attaining a certain level dependent upon the preselected shutter time and a light value as photoelectrically sensed, that is, an exposure value and, which is detected by a first comparator. The output of the first comparator is applied to the gate, so that the converter is set to memorize the exposure value therein. As the diaphragm presetting ring is moved from the maximum to minimum aperture position with production of a time variable output from a signal generator associated therewith, a second comparator responsive to the attainment of the time variable output of the signal generator to a level dependent upon the final output of the set converter produces an output which is applied to arresting means for the diaphragm presetting ring. This results in automatic adjustment of the position of the presetting ring. At the time the presetting ring begins to move, the diaphragm driving means is actuated causing the diaphragm means to be brought into engagement with the ring. Thus, an effective exposure aperture is established in the diaphragm means.
