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： This invention relates to photographic cameras, and more particularly to an exposure control circuit of the type in which an analog output representative of the object brightness level is converted to a digital signal which is factored into an exposure value, and the period of actuation of the camera shutter is controlled in accordance with this exposure value. Still more particularly, it relates to an improvement over this conventional type exposure control with respect to the A-D conversion. The prior art converts a voltage representative of the object brightness to a digital form by the use of an A-D converter such as of the follow comparison type which is characterized by the lack of integrating aspect in converting the input voltage to the corresponding digital signal. Therefore, when the illumination for the object being photographed is caused to flicker in a period of time shorter than the effective exposure time interval, an alternating current component is introduced into the input voltage of the converter. Accordingly, it is made impossible to effect accurate exposure control based on the digital signal representing the only object brightness level. The invention provides an exposure control circuit which is not susceptible of this alternate current component as it is removed in the course of the A-D conversion.
摘要翻译：本发明涉及摄影相机，更具体地说，涉及一种类型的曝光控制电路，其中表示对象亮度级的模拟输出被转换成被考虑到曝光值中的数字信号，以及照相机快门根据此曝光值进行控制。更具体地，涉及相对于A-D转换的这种常规型曝光控制的改进。现有技术通过使用诸如以下比较类型的A-D转换器将表示对象亮度的电压转换为数字形式，其特征在于在将输入电压转换为相应的数字信号时缺乏集成方面。因此，当拍摄对象的照明在比有效曝光时间间隔短的时间段内被闪烁时，将交流分量引入转换器的输入电压。因此，不可能基于表示唯一对象亮度级的数字信号来实现精确的曝光控制。本发明提供了一种曝光控制电路，其在A-D转换过程中被去除时不会受到该交流分量的影响。
