PURPOSE:To decrease the number of components and to attain unification of the function, by constituting a reader using two sensors having different reading picture width with a required minimum independent circuit. CONSTITUTION:The storage time in a sensor 13 is different from that in a sonsor 15. In irradiating a light from a fluorescent light 8 to a reading position of an original 1, the optical length is different from the sensors 13, 15 and the performance of the sensors 13, 15 is not always coincident. That is, there exists the variance in sensitivity, and the storage time is different depending on the two reasons above. The storage time is set independently to each sensor so that the same output is obtained for the sensors 13 and 15. If the storage time of each sensor is set the same, it is a hindrance to a common binary circuit. |
