PURPOSE:To simplify the constitution, and to reduce its cost, by using filters of 3 colors and 3 image sensors, obtaining each color information by shifting the timing, and executing the color printing by the shifted timing. CONSTITUTION:In a read part 30, trimming filters 41-43 of blue, red and green and 3 image sensors 51-53 are provided, and the sensors are placed so as to correspond to positions A, B and C of an original placing plate 31. Therefore, the sensors 51-53 obtain each color information of blue, red and green in the shape of shifted timing, it is stored in storage parts 61-63, and black information is stored in a storage part 64. A signal processing circuit 60 reads out storage information by this shifted timing, also operates transfer parts 74, 77, 80 and 83 of each color by its timing, and color printing is executed. Therefore, the constitution is simplified without using a dichroic mirror and an expensive prism, and the cost is reduced. |
