Abstract (en)

In a paper sheet thickness detection apparatus, precision of thickness detection of paper sheets is enhanced by suppressing vibration that occurs due to impact at a time of the paper sheets rushing in between a reference roller and a detection roller while ensuring maintainability. A paper sheet thickness detection apparatus detecting a thickness of a paper sheet includes a first unit including a reference roller, and a second unit including a detection roller that sandwiches the paper sheet with the reference roller to convey the paper sheet and displaces with respect to the reference roller according to a thickness of the paper sheet, and a thickness sensor that detects the thickness of the paper sheet based on a displacement amount of the detection roller. The first unit and the second unit are superposed such that the reference roller and the detection roller sandwich the paper sheet to form a conveyance path for the paper sheet, and are assembled to be openable and closable with a rotation axis provided on one end side of the conveyance path as a center. The second unit includes a vibration damping member on the thickness sensor.
