Abstract: When a switch is set to off, and a switch is set to on, the voltage of a SigOut terminal is stabilized with a reference voltage, and a bias voltage is applied to a capacitor. Changing the switch from on to off, with the bias voltage retained in the capacitor, a detection signal which is input via a SigIn terminal is amplified with the reference voltage as a reference, and an amplified signal is output from the SigOut terminal.

Abstract: An image reading apparatus includes a light source, an imaging optics system, an image pickup device unit, a memory, and a processor. The imaging optics system condenses scattered light reflected on an object to be imaged to form condensed light as an image. The imaging optics system includes plural cells arranged in a main scanning direction and each of which is an independent imaging optics system. Each of the cells includes a telecentric optics system at the document side. Two rows of cells are arranged in a sub-scanning direction. The cells in the rows are arranged zigzag in the main scanning direction to complement a formed image by the cells in the sub-scanning direction. The image pickup device unit is arranged to correspond to each cell. The processor can form a document image by reconstructing and combining image information stored in the memory into an image.
