Abstract

PURPOSE:To control exposure suited to ambient temps. by incorporating an iris stop into a cylinder holding a lens, and connecting this iris stop to a bimetal by way of interlocking lever and arm members. CONSTITUTION:A stop 4 is an iris stop incoporated into a lens holding cylinder 3 holding a lens. A stop interlocking member is movable by drawing an arc along the shell circumference of the lens holding cylinder and interlocks to the stop 4. An arm 6 connected freely rotatably is mounted to the leading end of the stop interlocking lever 5, and the other end of the arm 6 is connected freely rotatably to one end of a bimetal 7. The other end of the bimetal 7 is fixed to a frame 9 by a fixing member 8. The bimetal 7 operates in correspondence to the temp. change of a photoreceptor 1 whereby the iris stop is controlled.
