ABSTRACT:
A driver circuit provided with a shift signal generator for sequentially outputting shift signals at a predetermined time interval; a plurality of amplifiers respectively receiving a plurality of detection signals read out in parallel corresponding to a detectable object image pattern and respectively receiving the shift signals, wherein the plurality of amplifiers respectively amplify and output the detection signals inputted thereto based on the output timing of each of the shift signals inputted thereto; a data converter for outputting in time series each of the amplified detection signals outputted from each of the amplifiers based on the output timing of each of the shift signals and for generating time series read data. Power consumption and the amount of heat generation are suppressed in the driver circuit provided with means to individually control a supply state of electrical current to each of the amplifiers.
