First, the case where the bill S2a is inserted will be described. In the standby state described above, when the leading edge of the bill S1 is detected by the sensor 60 provided on the upstream side of the bill insertion machine B, the end of the bill S2a is moved to the bill holding mechanism (not shown) of the bill validator. ), The bill S2a is temporarily held in the bill insertion machine B. At this time, the banknote S2a in the standby state inserted from the banknote slot B1a is in the standby state at a position along the outer circumference of the upstream transport belt 9. Then, when the passing bill S1 comes in, the leading end portion of the bill S1 comes into contact with and overlaps the bill S2a, and cannot contact the transport belt 9, and the transport belt 9 moves the bill S1 to the bill S1 in the standby state. There is a problem that a state occurs in which the bill S1 is not conveyed without driving the. However, before this problem occurs (before the banknote S1 stops), the banknote S1 being passed by the auxiliary drive mechanism 43 contacts the round belt 47 of the pulley 44 and slides on the banknote S2 waiting to end the banknote S1. Transport to. The bill S2a is in contact with the conveyor belt 9 and the round belt 47, but since the end of the bill is held by the holding mechanism 55, the bill S2a is not overlapped with the passing bill S1 and is not conveyed, but only the bill S1. Is transported. After the bill S1 has passed through the bill insertion machine B, when the rear end of the bill S1 is detected by the sensor 70 provided on the downstream side, the holding mechanism for the bill S2a is released, and the bill S2 is subsequently pulled out.
The conveyance of a is performed. As a result, the banknotes can be reliably conveyed one by one.

For example, the light emitting element is a light emitting diode or a semiconductor laser, and the light receiving element is a photodiode or a phototransistor. Can be used.

Further, in the standby state of the banknote S2b inserted from the banknote insertion slot B1b, the banknote S2 moves the conveyor belt 9 to the banknote S.
It is a position where it does not interfere with the contact with 1, and the banknote S1 enters between the conveyor belt 9 and the banknote S2b, and continuous conveyance can be performed by the driving force of the conveyor belt 9. That is, in this case, the banknote S1 is conveyed by receiving a driving force from the conveyor belt 9, the holding function of the banknote S2b is released after the end of the banknote S1 passes through the banknote inserter B, and then the banknote S2b. The transportation of is started. As a result, banknote S1
And S2 are conveyed one by one without overlapping.
