PURPOSE:To improve optical accuracy by constituting a power variable lens block, an image formation lens, a CCD, and plural filters as a united unit. CONSTITUTION:The color and position of an original image are discriminated by a CCD unit 171 and developing units 121, 122, an erasing array 150 and multiplex copying unit 28 are controlled in accordance with the discriminated result. Since an optional color is selectively extracted from the color original and its image is formed, color copying can be easily attained. Since the image formation lens 173 and the CCD 171 form a pair, both the lens 173 and CCD 174 can be higly accurately held. The CCD unit 171 consisting of the lens 173, the CCD 174, etc. is arranged in a case 172 unitely and in parallel with the power variable lens block 8. Thereby, the lens block 8 and the CCD unit 171 can be easily moved. |
