Abstract:
1. An image sensor having a plurality of linear image sensor ICs arranged linearly, the image sensor comprising: a photoelectric conversion element circuit array for outputting an output signal according to the amount of received light; a switch element circuit array for reading an output of the photoelectric conversion element circuit array; a control circuit for controlling a signal that is read from the photoelectric conversion element circuit array; and a first reset switch for returning a common signal line that reads a signal read through the control circuit and the photoelectric conversion element circuit array to an initial state, wherein: the respective output terminals of the photoelectric conversion element circuit array are connected to the respective input terminals of the switch element circuit array; the respective output terminals of the switch element circuit array are connected to the common signal line; the common signal line is connected to a first electrode of the first reset switch; a second electrode of the first reset switch is connected to a reference potential terminal that is an initial potential; an image signal outputted from the common signal line is connected to the input terminal of a chip select switch that selectively functions; the output terminal of the chip select switch is connected to the signal output terminal; a delay element that delays by m clocks corresponding to the scanning circuit is connected in series between an input terminal of a first scanning circuit and a signal start signal terminal which drives the photoelectric conversion element circuit array; and the delay element has a function for delaying the start position of the output signal of the first photoelectric conversion element.
