PURPOSE:To make unnecessary the optical axis matching by constituting one group of two sensors which can discriminate a prescribed color, making them continuously move forward along the front of a color detection object, separately detecting it two times, and inputting it to the color discriminating circuit. CONSTITUTION:Design paper 3 is wound around the pattern drum 18, the sensors 1, 2 and the design paper 3 are opposed to each other, and the design paper 3 is retrieved in order in the horizontal direction. In this case, the first sensor 1 precedes the sensor 2 by (n) pitches, a color data is inputted to the optical axis compounding (n)-bit shift register 32 through the FF31, and at the same time, a timing signal is inputted to the FF31 and the optical axis compounding (n)-bit shift register 32. When the second sensor 2 has attained to the detection unit, all the data that have been detected by the first sensor 1 are outputted already. And, the color data of the first and second sensors 1, 2 are discriminated with respect to color by the color discriminating circuit 33, and are outputted in accordance with sequence of designated colors through the pattern data output priority designating circuit 34. According to such a constitution, it is possible to make unnecessary the optical axis matching. |
