摘要： An exposure time control device includes electromagnets for causing corresponding leading and trailing shutter curtains in a camera to travel. A second timer circuit, which is adjustable, is arranged to count a correction time in response to operation of a first timer circuit which counts an exposure time for the camera. After the lapse of the correction count time of the second timer circuit, the electromagnet for the leading shutter curtain is actuated, and then the electromagnet for the trailing shutter curtain is actuated after the lapse of the exposure count time of the first timer circuit. Exposure time errors which would otherwise result from overlapping of the shutter curtains and response delay of the trailing shutter curtain electromagnet, thus can be corrected by adjustment of the second timer circuit.

摘要： The present invention relates to the exposure compensation information forming apparatus for a camera, particularly for forming the aperture and the totally opened aperture value information. Until now in order to compensate the totally opened aperture value contained in the output of the light measuring circuit and the aperture value the information setting means for the totally opened aperture value and that for the aperture value are provided, whereby both setting means are mechanically engaged with each other so as to form the totally opened aperture and the aperture information. Thus, the engaging mechanism of both of the above means is complicated, which is inconvenient. The present invention provides an exposure compensation information forming apparatus by means of which the aperture information can be composed from the totally opened aperture with a very simple circuit composition so as to overcome the above disadvantage.
