摘要： A paper detecting apparatus includes a transfer base, a first and a second linear sensors, and a data processor. The transfer base transfers a paper in a predetermined transfer direction, and the paper includes a first and a second side edges in parallel to each other. The first linear sensor includes a first linear reading region for detecting the first side edge of the paper. The second linear sensor includes a second linear reading region for detecting the second side edge of the paper. The data processor processes the data obtained by the first and the second sensors. The first and the second sensors are arranged in a manner such that the first and the second linear reading regions are positioned transversely to the transfer direction. The data processor detects the tilt angle between the paper and the transfer direction based on the positional information of the first and the second side edges obtained by the first and the second sensors.

摘要： An image reading apparatus includes image sensor chips and control chips for controlling the operation of the image sensor chips. Each image sensor chip, including a plurality of photoelectric converters, performs the outputting and resetting of accumulated electric charge due to light detection. Each control chip includes resolution data input terminals for inputting resolution data to specify resolution, and also a reset signal generator for generating a reset signal for performing the resetting of the accumulated electric charge. The reset signal is generated in a selected one of the cycles that corresponds to the resolution data inputted into the terminals.

摘要： An image reading apparatus includes a plurality of sensor IC chips aligned in a row. Each of the sensor IC chips incorporates a plurality of light receiving elements. The plurality of light receiving elements successively output image signals as serial analog signals corresponding to received amount of light upon receiving light from an object to be read. The number of the sensor IC chips is an integer multiple of three. The sensor IC chips are divided into blocks. The number of the blocks is an integer multiple of three. The image signals are outputted on a block-by-block basis.

摘要： A reciprocal contact-type image sensor includes a case having an upper surface formed with an opening, a cover glass closing the opening and providing a linear reading region extending in the primary scanning direction. A sheet as an object to be read, coming into contact with the linear reading region, is reciprocally moved in the secondary scanning direction which is perpendicular to the primary scanning direction. The opening is defined by a pair of edges spaced in the secondary scanning direction. Each of the edges includes a convex surface having a top positioned above the outer surface of the cover glass.
