Claim 2:
3. The detection device according to claim 2, wherein
the detector comprises:
a differential amplifier circuit configured to output a potential difference between voltages generated in the detection elements adjacent in the second direction;
a first capacitive element coupled to a non-inverting input terminal of the differential amplifier circuit;
a second capacitive element coupled to an inverting input terminal of the differential amplifier circuit; and
a switch circuit configured to electrically couple the output signal line to the non-inverting input terminal or the inverting input terminal of the differential amplifier circuit by switching between the non-inverting input terminal and the inverting input terminal in synchronization with selective switching of the read control scan line.
