Abstract

PURPOSE:To prevent abnormal sound from being generated, by providing a member for producing a load due to superposition so as to apply the load to a separating member in order to change the characteristic frequency of the separating member during a paper sheet passing. CONSTITUTION:A tension frame 30 is provided on the upper side of a conveying roller 16 so that it is rotatably supported by a pin 30 while a superposition 32 is attached as a load generating means, and a brake roller 34 as a separating member 34 is unrotatably attached to a bridging shaft 33 so that this brake roller 34 is made into contact with the peripheral surface of the conveying roller 16 under a constant pressure given by the superposition 32. With this arrangement, during a paper sheet (a) passing between the conveying roller 16 and the brake roller 34, the brake roller 34 vibrates, and the characteristic frequency of vibration of the brake roller 34 varies since the superposition 32 applies a load to the brake roller 34, thereby it is possible to prevent generation of abnormal sound due to vibration.
