Abstract
PURPOSE: To make effective use of space and achieve smaller size and smaller electric power by disposing the driving mechanism part of shutter blade in the diagonal line direction assuming the longest side of the square space sandwiched by a film patronage chamber and film winding chamber.
CONSTITUTION: In the camera comprising disposing the electromagnetically driven shutter which performs the opening and closing operations of a shutter blade 7 by rotating a sector ring 5 with an electromagnetically driving mechanism in the space formed at the intermediate of the film patronage containing chamber 1 and film winding mechanism containing chamber 2 in the camera, the driving mechanism part of the shutter blade is constituted by at least a pair of driving coils 3 and stationary magnets 4 and these are disposed axis-symmetrically with the photographing optical axis as a center in the diagonal line direction assuming the longest side of the foregoing space, by which the effective coil length of the driving part may be taken long and the output of the electromagnetic driving device may be increased.
