PURPOSE:To contrive the improvement of the image of a copied picture to an original by setting the print density of a picture data variably at data print based on color discrimination information of the picture data. CONSTITUTION:A linear image sensor 15 outputs a color discriminating signal (R, G, B) in response to a reflected light from the face of an original B synchronously with the CCD exposure timing signal from a timing signal generating section 52. Its printing picture signals are '1', '1', '0' in the blue region of the picture data, and a thermal head 21 uses a thermal head driving circuit 63 to be driven at a reference energizing time for twice only among three time. Moreover, its printing picture signals are '1', '0'... in the red region of the read picture data and the thermal head 21 is driven by a reference energizing time by the thermal head driving circuit 63 for once among two times. Thus, the picture data stored in the picture data memory 60 is printed out onto print paper A in four color tones including white/block/blue/red by operating movably the handy copy machine main body 1 in such a manner. |
