Claims

[Scope of utility model registration request]

An image sensor is arranged perpendicularly to the conveyance direction of paper sheets and scans the paper sheets perpendicularly to the conveyance direction, and the scanning clock of this image sensor is counted, and n(n first and second n-ary counters that output when the counting content is bits (arbitrary number), and presetting a predetermined value in the first counter at the start of each scan of paper sheets; and counter value presetting means for presetting a complementary value of the predetermined value for the n bits in the second counter, and means for sampling and holding the output of the image sensor at the time of output of the first and second n-ary counters. A paper sheet reading device which is configured to read the pattern of two tracks symmetrical about the central axis of the transported paper sheet.
