I do. If the end of the banknote passes the end sensor 30 within a predetermined time, the end banknote detecting means 40
No signal is output to the control means 35, whereby the control means 35 determines that the bill has flowed out of the exit 25,
Thus, after a notification 57 indicating that the ticket is genuine, the device stands by in a waiting state 58.

If the banknote end cannot pass through the end sensor 30 within a predetermined time 59, the control means 35 sends a conveyance motor stop means.
A conveyance motor stop signal is transmitted to 42, the conveyance motor 31 is stopped 60, and the bill jam notification unit 44 notifies the bill jam 61
Then, until the jammed banknotes are removed 62, the notification by the banknote jamming notification means 44 is performed (until the banknote detection signal of the terminal sensor 30 disappears). After the jammed bill is removed, the state returns to the standby state 58.

As described above, according to the present embodiment, by providing the termination sensor 30 near the exit 25, it is possible to reliably detect a banknote jam after passing through the identification sensors 28 and 29.

Next, the operation at the time of power supply or at the time of recovery from a power failure will be described with reference to FIGS. 1 and 4, using FIG.

First, when power is supplied 63 to the bill validator 21, the presence / absence detection 64 of the bill is first performed by the optical sensor 28, and if there is a bill, a bill present signal is output from the identification means 39 to the control means 35. Accordingly, the control means 35 determines that there is a banknote, the banknote notification means 44 notifies the banknote jam 65, and until the jammed banknote is removed 66 (until the banknote detection signal of the optical sensor 28 disappears). An announcement is made by 44.

If there is no bill, then the end sensor 30 detects the presence of the bill /
No detection 67, if there is a bill, the end bill detection means
A bill present signal is output from 40 to the control means 35, whereby the control means 35 determines that there is a bill, and the bill jam notification means 44
Alerts you of jams and removes jammed banknotes
Until 69 (until the detection signal of the bill by the end sensor 30 disappears), the notification 68 by the bill jam reporting means 44 is performed. If there is no bill, the state directly goes into the standby state 70.

By providing the terminal sensor 30 near the outlet 25 as described above, the banknote can be detected by the terminal sensor 30 at the time of power supply or at the time of recovery from power failure. Even if an instantaneous power failure occurs after passing and before a genuine note is notified, it is possible to notify the clogging of the banknotes, so that the banknotes are not left as they are.

Effect of the Invention As described above, the present invention is in the vicinity of the exit of the bill passage, and by providing an end sensor at a position slightly away from the center of the bill passage, after the end of the bill passes the identification means, If it does not pass the end sensor even after the lapse of the predetermined time, it is used to close the banknote,
Clogging of banknotes can be reliably detected.

Further, since the end sensor is provided at a position slightly away from the center of the bill passage, a stable output can be obtained from the end sensor even if a folded bill is inserted.
