Inside the housing 1, a horizontal bill passage 4 and a vertical bill passage 5 which are substantially L-shaped and continuous to communicate with the insertion slot 2 are formed. Above the bill passage 4, a magnetic head 6 is provided as means for discriminating the authenticity of the bill, and a head pressing roller 7 is disposed on the side facing the magnetic head 6. Pulleys 8 and 9 are disposed before and after the head pressing roller 7, and a belt 10 is hung between these pulleys in parallel. The pinch roller 11 presses the pulley 8 from above the belt 10.

On the other hand, a pair of driving pulleys 12 and 12 are arranged at a distance on one side of the vertical bill passage 5, and driven pulleys 14 and 14 corresponding to these driving pulleys are arranged below the housing 1. Have been. Each drive pulley 12 and driven pulley
The storage belt 15 is hung in parallel between the pair of 14.
Inside these storage belts 15, there is a bill pushing device.
16 is provided, this pushing device 16 is a storage belt
A push plate 17 for pressing the bill B sent along the bill passage 5 to the side by 15, one end is pivotally attached to the back surface of the push plate 17, and the other end is inserted through a long hole. It comprises a pair of link rods 19 and 20 attached to the fixed shaft 18 and an eccentric cam 21 driven by a motor around the rotation center 0. The push plate 17 is spring-biased toward the pushing device 16 by coil springs 22 and 22. A stacking box 23 for stacking the bills B pressed by the pushing device 16 is provided on the other side of the bill passage 5. A compression plate 24 is disposed in the accumulation box 23, and is urged to the left in the drawing by a spring bar 25.

Incidentally, a shutter plate 26 is provided in a connection area of the bill passages 4 and 5, and one end of the shutter plate 26 protrudes into the bill passage 5. The shutter plate 26 is pushed by the bill B traveling in the bill receiving direction and automatically retreats to the outside of the passage, but functions as a stopper for the bill moving in the opposite direction.

Thus, according to the present invention, the bottom plate 27
A device 28 for preventing the banknote from surviving is provided below the inner end of the banknote. As shown in FIG. 2, the pull-out preventing device 28 includes a bracket plate 29, a pull-out preventing lever 30,
And a pivot shaft 31 for coupling the two. The bracket plate 29 is composed of mounting lugs 29a, 29a, and a U-shaped bracket body 29b having an open upper portion for integrally connecting these.

On the other hand, the pull-out prevention lever 30 has a pair of claw members 32 extending the toe 32a obliquely upward and away from the bill insertion slot 2.
And a hook groove 33 is formed above the claw member 32. These pawl members 32 are integrally connected by a connecting plate 34, and a tongue piece 35 is provided upright at substantially the center. The tongue piece 35 effectively prevents the lower end of the bill stored in the stacking box 23 from hanging down into the bill passage 5.

As shown in FIG. 3, a stop surface 32b is formed behind the lower surface of the claw member 32. Further, the pull-out preventing lever 30 is pivotally supported so as to be rotatable around a pivot shaft 31, and a coil spring 36 is mounted on the pivot shaft 31, and one end 36a is a side surface of the connecting plate 34. , And the other end 36b is locked by the side surface of the bracket body 29 of the bracket plate 29. Accordingly, the pull-out preventing lever 30 is spring-biased around the pivot shaft 31 in the counterclockwise direction in FIG. 1, that is, in the direction in which the claw member 32 blocks the bill passage 5, by the spring force of the coil spring 36. I have.

Next, with reference to FIG. 4 to FIG. 7, a description will be given of a mode of preventing fraud in a case where a bill having the tape T stuck to the rear end of the regular bill B is once received and then pulled out due to fraud.

In FIG. 4, the regular banknote B to which the tape T is connected is
In the same manner as usual, the bill B is inserted into the bill passage 4 from the insertion slot 2, and the bill B is identified by the magnetic head 6 as true or false. Then, after the normal bill B advances the bill passage 5 by retracting the shutter plate 26 to the outside of the passage, the pull-out prevention lever 30 is retracted against the spring force of the coil spring 36 and introduced into the bill passage 5. Is done. When the bill B reaches the stacking position corresponding to the push plate 17, the bill is stopped, the eccentric cam 21 rotates twice, and the push plate 17 reciprocates two times. The push plate 17 pushes the bill B into the stacking box 23 against the compression plate 24. In order to store the banknotes stopped at the stacking position in the stacking box, the eccentric cam 21 may be rotated once and the push plate 17 may be reciprocated one time. It is better to make the push plate 17 reciprocate two times by rotating the 21 twice.

Here, as shown in FIG. 6, even if the wrongdoer attempts to pull out the bill B by inserting the celluloid plate 38 into the bill passage 4 from the insertion slot 2 and moving the shutter plate 26 out of the passage. Then, the end of the bill B is hooked on the hook groove 33 of the pull-out preventing lever 30, so that the bill B is prevented from being pulled out.

By the way, when the wrongdoer inserts the celluloid plate 38 further deeply and presses the claw member 32 of the pullout prevention device 28 to pull out the bill B, the tongue piece 35 moves the foremost bill B to the back. Since it acts so as to be pushed in, the bill B is prevented from being pulled out. As a result, the tongue piece 35 can effectively prevent the banknote from sagging and also effectively act against fraudulent attempts to pull out the banknote.

(Effects of the Invention) As is clear from the above description, according to the present invention, a pull-out preventing lever is provided in a bill passage and normally urged to block the bill passage by a spring force. Once the bills with tape attached are once stored in the stacking box, even if a thin plastic plate is inserted to pull out the bills, the ends of the bills are caught in the hook groove of the pull-out prevention lever. It is possible to reliably prevent the bill from being pulled out to the outside.
