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.
