PROBLEM TO BE SOLVED: To solve the problem that the scale of a circuit is increased, for example, accessory circuits are increased since it is necessary to increase shift registers in order to switch resolution in a conventional image sensor unit. SOLUTION: A selector 14 to be controlled by a resolution switching signal is arranged between shift registers 9 for supplying signals to the gates of analog switches 7 for controlling the outputs of a plurality of linearly arranged photoelectric converting elements 6, and the logic of the resolution switching signal is switched so that the connection of the selector 14 can be changed, and that the connection of the shift register 9 can be changed. Thus, it is possible to switch the resolution of the image sensor.
