By preventing the banknote A from being pulled out by the locking member 43, and when the banknote A passes between the leading end of the locking member 43 and the other passage surface 31 a, Since the banknote A pressed to the passage surface 31a side is locked to the stepped portion 31c provided on the other passageway 31a, the banknote A is prevented from being pulled out by the stepped portion 31c. It is possible to reliably prevent cheating. In this case, since the banknote A can be prevented from being pulled out by the step portion 31c of the other passage surface 31a, there is no need to provide the locking member 43 on the other passage surface 31a side, and the number of components is reduced and the construction is inexpensive. be able to. Moreover, since the latching member 43 is comprised so that it may rotate by the contact with the banknote A, banknote clogging does not arise and conveyance failure can be prevented.
[0042]
Moreover, since the said level | step difference part 31c was formed covering the full width of the banknote conveyance path B, the banknote A can be latched to the level difference part 31c in any position of the width direction of the banknote conveyance path B, and the level | step-difference part 31c and It is possible to more reliably prevent the banknote A from being pulled out by the locking.
[0043]
Further, since the hole 31b for receiving the leading end side of the locking member 43 is provided in the other passage surface 31a, the bill A to be locked to the locking member 43 is inserted into the leading end of the locking member 43 and the other passage surface 31a. The banknote A can be more reliably prevented from being pulled out by being locked with the locking member 43.
[0044]
In addition, in the said embodiment, although what provided the level | step-difference part 30c of the other channel | path surface 30a in one place was shown, if it is provided in two or more places of a banknote conveyance direction, it will be made into the banknote A to the some level | step-difference part 30c. The banknote A can be more reliably prevented from being pulled out.
[0045]
In the above embodiment, each locking member 43 is biased toward the passage surface 31a of the first transport unit 30 by a biasing means (not shown). However, as shown in FIG. By shifting the center of gravity G toward the passage surface 31a side by a predetermined distance L from the center of the support shaft 43a, it is possible to form the locking member 43 so that it can be pressed against the passage surface 31a by its own weight.
