Abstract: A document sensing device is herein disclosed whereby the signal-to-noise ratio inherent in a large-size image sensor is enhanced by a reduction in system noise. A plurality of photodetectors are connected to a plurality of storage MOSFETs. Two signal wires are connected to alternating groups of the MOSFETs. A shift register is provided which sequentially turns on the MOSFETs. The connections of the groups of MOSFETs and the sequential turn-on sequence are both preselected such that at the same time one group of MOSFETs is outputting a composite signal (information plus noise) on one signal wire, the immediately preceding group of MOSFETs is outputting a signal (noise only) on the other signal wire. Upon the combination of the signals in a differential amplifier, the noise signal is thus eliminated from the composite signal.

Abstract: An original reading device comprising a plurality of light sensing elements connected to output signal lines via MOS transistors. A row of light sensing elements is divided into blocks of elements. Each block has a pair of signal output lines. Groups of consecutive MOS transistors are alternately connected to the two signal lines, each group comprising at least two MOS transistors. The transistors are turned on twice each reading cycle, the time between turn-on of a given MOS being sufficiently short so that the output signal contains only noise, as compared to the photosignal plus noise obtained during the first turn-on. The turn-on sequence is such that the first turn-on of any group coincides with the second turn-on of the preceeding group. The signal output lines are connected as the inputs of a differential amplifier. Thus the noise signals are subtracted from the photosignal plus noise signals to result in outputs having only photosignals.

Abstract: A signal processing circuit for an original reading device substantially eliminates noise from a photosignal output. Light sensing elements are connected to one of two signal lines on an alternating group basis, two or more elements per group, via MOS switching transistors. Each element is accessed twice during each cycle by switching its associated MOS twice. The noise-only signal resulting from the second switching is subtracted from the photosignal plus noise resulting from the first switching by applying the signal lines to a differential amplifier. The output signal containing reduced nose is periodically inverted to compensate for inversion of one signal line in the differential amplifier and is then subjected to integration to remove the remaining noise.
