PURPOSE:To obtain a small-sized, simplified copying machine capable of multimode selection at low price by moving a movable member manually and selecting a copy mode, and detecting the position of the movable member electrically and changing copying operation conditions. CONSTITUTION:Copy modes such as an enlarged copy, a life-size copy, a reduced copy, a white frame formation, and a variable magnification mode are changed by rotating an operation dial 40 manually in six stages at intervals of, for example, 30 deg.. The rotation position of the operation dial 40 when detected is transmitted electrically to a microcomputer by a rotary switch 47 fixed coaxially with the dial through a bundle of lines 48 and a selector cam 44 rotates according to the rotation of the operation dial 40 to set the claw 50a of a coupling plate 50 at a mode position corresponding to the rotation of the operation dial 40 through a slider 46 and the coupling plate 50. Then, a control ring 51 rotates to rotate a lens moving cam 57, and a zoom lens 3 is moved to a corresponding mode position through levers 58 and 59. |
