Zusammenfassung:	A linear image sensor includes N units, a readout circuit, and a control unit. Each unit includes a photodiode and a source follower amplifier. The source follower amplifier includes a MOS transistor, an operation control switch, and a current source. A gate of the MOS transistor is connected to a cathode of the photodiode via the MOS transistor. The operation control switch is provided between a source of the MOS transistor and a connection node. The current source is provided between the connection node and a second reference potential input terminal.
