Abstract
A data reading device of the type employing a plurality of image sensors for reading separated colors is provided with a delay device in the processing circuitry of at least one of the image sensors. The delay device can be set to delay the signal output from the associated image sensor to an arithmetic circuit for a variable time corresponding to a multiple of the line scanning period. In this manner, the image sensors need not be so accurately positioned that the same line is read by each of the several sensors at the same time, but the picture data signals for the same line can nonetheless be fed to the arithmetic circuit simultaneously.
