ABSTRACT:
A device for detecting the thickness of sheets comprising a seizing roller on a first shaft mounted for counterclockwise rotation and a feed roller on a second shaft mounted for clockwise rotation and having a diameter smaller than that of the first shaft. The seizing roller includes a peripheral portion having a peripheral length slightly longer than each of bank notes to be transferred and cooperating with the feed roller and a recess for receiving the forward end of each bank note. The forward end of the bank note received in the recess is engaged between the feed roller and the peripheral portion of the seizing roller during their rotation to pass the bank note between the rollers. There is a displacement detecting device for detecting the displacement of the smaller roller shaft occurring during the passage of the bank note between the rollers.
