Abstract

A paper sheet counting machine is disclosed, wherein sheet catching rollers are rotated to feed out paper sheets one after another by means of a friction. A sheet separating roller and a sheet separating plate cooperate to transport the fed out paper sheets, the former having a friction coefficient in connection with the paper sheets which is larger than a friction coefficient existing between the paper sheets themselves and the latter having a same nature of friction coefficient with the sheet separating roller so that the roller is rotated to transmit a transportation power to each of the paper sheets while the plate gives a braking power to each of the paper sheets thereby to prevent more than two paper sheets are transported in an overlapped condition. A counter is operated to count the paper sheets as these are transported past the counter while an angle sensor is operated to detect the rotation angles of the roller to check the width of the paper sheets thereby to discriminate if more than two paper sheets are transported in an overlapped condition, and if so, a warning signal is produced.
