摘要： An apparatus for setting an exposure control factor into a camera in the form of a digital signal without using a code plate or a plurality of switches. A pulse train is fed to a binary counter through an AND circuit which, upon selective receipt of gating-on and gating-off signals, operates to initiate and terminate flow of pulses therethrough respectively. When the counter has counted the selected number of pulses, the photographer who is viewing a digital display unit cooperative with the counter to detect this pulse number may actuate a button to produce the gating-off signal, thereby a corresponding desired value of the exposure control factor is set into the camera as a function of the number of pulses counted.

摘要： The present invention relates to a camera with a displacement means for controlling the exposure amount as the function of the mechanical displacement position. The displacement means are so designed that a brush is slid over a comb-shaped conductive pattern mechanically linked with the displacement means so as to convert the displacement position of the displacement means into a pulse number. Further, when the pulse number reaches a certain determined value, the displacement means is stopped in such a manner that the pulse number corresponds with the exposure amount and characterized in that, by determining the position at which each conductor of the comb-shaped conductive pattern is provided, relative to the position at which the displacement means stops in accordance with the displacement speed of the displacement means, the displacement amount of the displacement means due to the time delay since the pulse number reaches a certain determined amount till the displacement means actually stops is compensated so that the pulse number always corresponds with the displacement position in a precise way.
