<P>PROBLEM TO BE SOLVED: To solve the problem that it is necessary to improve component precision and add a positioning member in order to prevent the deterioration of detecting precision and enhance the detecting precision. <P>SOLUTION: A color sensor 42 is displaced between an image detection position and a retracting position retracting from the detection position by a motor 68 and cams 66 and 67, the displacement range of the sensor that the output of the color sensor is a predetermined value or above is stored on the basis of the relationship between the position of the displaced color sensor 42 and the output of the color sensor 42. When the image is detected by the color sensor, the motor 68 and the cams 66 and 67 are controlled (S2 to S4) based on the stored displacement range. <P>COPYRIGHT: (C)2007,JPO&INPIT |
