Description

  The present invention relates to a rotary pullout prevention unit having an arrow blade-like fin that prevents unauthorized pulling out of a valuable paper sheet from the inside of a document handling apparatus by pulling a thread connected to the valuable paper sheet. .

  The banknote discriminating device mounted on vending machines, money changers, cash dispensers, automatic deposit machines, game machines, etc. is a thread that is fixed in advance to the trailing edge of banknotes after finishing the discriminating operation of inserted banknotes. In order to prevent a fraudulent act of pulling out a bill by pulling back a pulling means such as a string or a tape, a bill withdrawal preventing device for preventing the withdrawal of the bill connected to the withdrawal means is usually provided.

  For example, in Patent Document 1 below, long grooves along the conveyance direction of a banknote are provided on a convexly curved path surface forming a bent banknote path, and a plurality of long grooves are arranged in the transverse direction of the banknote path. Disclosed is a banknote handling apparatus provided with a protrusion protruding from each side wall or bottom surface. In this banknote processing apparatus, a first surface that is inclined to the bottom surface side of the long groove and guides the yarn conveyed together with the banknote into the long groove, and a bottom surface side of the long groove at a horizontal or smaller angle than the first surface. The protrusion is provided with a second surface that is arranged so as to be inclined to prevent the thread that once enters the long groove from being detached from the long groove. When the yarn stuck to the conveyed banknote enters the long groove without moving on the side wall of the long groove, the yarn guided to the first surface of the protrusion moves toward the bottom of the long groove. The yarn that reaches the bottom of the long groove is restricted to the inside of the long groove by the second surface of the protrusion and cannot return into the bill passage. For this reason, if the thread | yarn stuck on a banknote is pulled, a banknote will be latched by the side wall of a long groove, the further movement of the withdrawal direction of a banknote will be blocked | prevented, and withdrawal of a banknote will be prevented.
