Abstract

PURPOSE:To compensate the focusing position, by turning a cam right that contacts slidably with the rotary edge face of a lens barrel. CONSTITUTION:A cam ring containing an edge face cam 2a and a gear 2b is set opposite to a pin 4b on the rotary edge face of a lens barrel 4 and pressed to a ground plate 1 by a spring member 7 and a waveform washer 6, the ring 2 is turned by turning a minor gear 3, and as a result the barrel 4 moves toward the optical shaft by a pin 4b which contacts slidably with the cam 2a to perform the compensation of the focusing position. After the compensation of the focusing position, the gear 3 is fixed to the plate 1 by a screw 9 and a washer 9. Thus the ring 2 is also fixed. The focusing of a photographing lens itself is carried out by shifting a manual operation member 5 toward directions A and B.
