Brake. In other words, in the feeding mode, when the topmost banknote P is fed to the predetermined position in accordance with the driving of the belt transport body 303,
By bringing the brake pad 307a into contact with the lower banknote P, it is possible to prevent inconvenience in which the lower banknote P is double-fed.

The brake pad 307a is arranged so that the front end thereof overlaps the central portion in the front-rear direction (the central portion in the bill dispensing direction) of the intermediate pool internal space (the bill dispensing chamber). In other words, the front end side of the brake pad 307a overlaps with the central portion of the bill most likely to be broken. Therefore, the brake effect can be enhanced by bringing the brake pad 307a into contact with the mountain-folded position of the banknote P, and the inconvenience that the pressing force of the brake pad 307a acts in the direction in which the banknote P is sent out can be avoided. It is possible to prevent a delay in brake timing by eliminating a useless descending stroke of 307a as much as possible. In addition, the brake pad 307a of the present embodiment is arranged so as to face the feeding direction of the banknote P, and its front and rear middle portion is supported so as to be rotatable up and down around a pin 307e that faces left and right. 307a
When the brake pad contacts the inclined surface of the banknote P, the brake effect can be further enhanced by causing the brake pad 307a to follow the inclined surface.
