    • A film transporter is coupled to a counter which counts the number of used film frames. A film detector detects a film when the count signal is "0," i.e., a state where the counter for counting the number of used film frames is reset. When it is detected that the camera has no film roll loaded therein, the film transporter is disabled to advance or rewind the film roll. There is provided a film travel detector adapted to stop further travel of the film roll after the number of pulses output every time the film roll travels by one frame has reached a predetermined number and, when the camera has the film roll loaded therein, the predetermined number is changed depending whether the count signal is "0," so that a common control system effects initial film advance and advance of each frame following the initial film advance.
    • 胶片传送器连接到计数器,该计数器对所使用的胶片帧的数量进行计数。 当计数信号为“0”时,胶片检测器检测胶片,即用于计数所使用的胶卷帧数的计数器被复位的状态。 当检测到相机没有装载胶卷时,胶片传送器被禁止推进或倒带胶卷。 提供了一种胶片行进检测器,其适用于在每次胶片卷行进一帧之后输出的脉冲数达到预定数量之后停止胶卷的进一步移动,并且当相机具有胶卷装入时,预定的 根据计数信号是否为“0”来改变数量,使得公共控制系统在初始胶片提前之后实现每帧的初始胶片前进和前进。

    • In a rangefinder apparatus for projecting a light beam toward a target object a number of times; detecting light of the light beam reflected from the target object, and successively integrating output signals corresponding to the distance to the target object to carry out rangefinding; a voltage of an integrating capacitor in a rangefinding routine is detected, and the rangefinding routine is forcibly terminated if the voltage of the integrating capacitor is out of a preset range. Since the rangefinding routine is forcibly terminated if the voltage of the integrating capacitor in the rangefinding routine is outside of the preset range, malfunctions of a signal processing IC can be detected.
    • 在用于将光束投射到目标物体的测距装置中多次; 检测从目标物体反射的光束的光,并且将与距离对应的输出信号依次积分到目标物体上进行测距; 检测测距程序中的积分电容器的电压,并且如果积分电容器的电压超出预设范围,则强制终止测距程序。 如果测距程序中的积分电容器的电压超出预设范围,则由于测距程序被强制终止,所以可以检测到信号处理IC的故障。
