DESCRIPTION OF EMBODIMENTS

(6) Hereinafter, one of embodiments of the present invention will be described with reference to the drawings.

(7) FIG. 1 is a front-side perspective view of a coin storage cassette 8 which is provided with a coin tube 6 according to an embodiment of the present invention, and FIG. 2 is a side cross-sectional view of a main part illustrating a state where coins are stored in the coin tube 6 according to the embodiment of the present invention. Structures of the coin storage cassette 8 and the coin tube 6 according to the embodiment are the same as structures of a coin storage cassette 8 and a coin tube 6 of the related art, which have been described above, except for parts to be described hereinafter. Accordingly, members among components in this embodiment that are equivalent to the components of the above-described coin tube 6 of the related art will be denoted by the same reference signs, and the detailed description thereof will be omitted.

(8) This coin tube 6 assumes that a coin enters the coin tube 6 from a position deviated from the center of the coin tube 6 to the rear, which is similar to the coin tube 6 of the related art. This coin tube 6 is provided with a coin posture conversion unit 9 including a plate-shaped member 9a on an inner wall surface of a coin entry port. This coin posture conversion unit 9 including the plate-shaped member is provided on the inner wall surface, which is on a side close to an entry point of the coin, in order to guide the entering coin and is inclined to the lower side. In addition, the plate-shaped member 9a of the coin posture conversion unit 9 has a shape provided with a semicircular cut in order to cause the coin whose posture has been converted by the coin posture conversion unit 9 to fall without being stuck.

(9) The coin entering the coin tube 6 abuts on an inner wall of the coin tube 6 and the coin posture conversion unit 9, and a progressing posture thereof is converted into a posture almost horizontal as falling to slide along an inclination of the coin posture conversion unit 9. Thereafter, the progressing posture of the coin falling inside the coin tube 6 is further changed as colliding with the inner wall of the coin tube 6, and generally becomes further close to the horizontal posture at the time of reaching a bottom of the coin tube 6. In general, coin erection is not generated in a case where a coin reaches a bottom surface of the coin tube 6 or a top surface of a stored coin in a posture almost horizontal since the coin erection is generated in the coin tube 6 when a coin reaches the bottom of the coin tube 6 or a top surface of a stored coin in a posture almost vertical. However, it is difficult to manage or control a posture of a coin in the middle of falling in the coin tube 6, and thus, a posture of each coin falling on the top of the stored coin varies depending on the number of coins stored in the coin tube 6.

(10) Thus, not only the plate-shaped member 9a guiding the coin but also a rib-like protrusion 9b is provided in the coin posture conversion unit 9 of the coin tube 6. The rib-like protrusion 9b is configured to cause an inclination in a direction vertical to an inclination, which is caused by the inner wall near the coin entry port of the coin tube 6 and the plate-shaped member 9a, in addition to the latter inclination. Thus, the rib-like protrusion 9b is provided only at one side between both sides of a center line cl in a progressing direction of a coin on the coin posture conversion unit 9, in the plate-shaped member 9a of the coin posture conversion unit 9.

(11) Since the rib-like protrusion 9b is present, the coin that has entered the coin tube 6 and abutted on the coin posture conversion unit 9 gently rotates in the direction vertical to the inclination caused between the inner wall near the coin entry port and the plate-shaped member 9a due to the momentum of free fall and the inclination caused by the rib-like protrusion 9b. As a result, an inertial force for rotation in a transverse direction works on the coin falling in the coin tube 6. Further, even when the coin having such an inertial force lands on the bottom surface of the coin tube 6 or the top surface of the stored coin in the posture almost vertical, the coin hardly maintains the posture at the time of landing due to the inertial force. Thus, it is possible to suppress generation of the coin erection due to the presence of the rib-like protrusion 9b.

(12) As described above, the coin tube 6 includes the coin posture conversion unit 9, which converts the posture of the coin into the posture almost horizontal, at the coin entry port, and further, the coin posture conversion unit 9 applies a rotational force in a direction vertical to the progressing direction to the coin on the coin posture conversion unit 9. This application of the rotational force can be implemented by forming the coin posture conversion unit 9 in a shape asymmetric to the center line cl in the progressing direction of the coin on the coin posture conversion unit 9. In the coin tube 9, the coin posture conversion unit 9 is formed in the asymmetric shape by providing the rib-like protrusion 9b only at one side between both sides of the center line cl in the progressing direction of the coin on the coin posture conversion unit 9. As another configuration, it is possible to consider a configuration in which rib-like protrusions having different heights are provided, respectively, at both the sides in the center line cl in the progressing direction of the coin on the coin posture conversion unit 9, a configuration in which the plate-shaped member 9 is directly caused to be inclined laterally instead of providing the rib-like protrusion, and the like.

(13) According to the coin tube 6 according to the above-described embodiment is capable of suppressing generation of the coin erection more than the coin tube of the related art.

(14) Although one of the embodiments of the present invention has been described as above, the coin tube of the present invention is not limited to the embodiment. It is possible to adopt a suitable configuration as long as satisfying the configurations described in the claims.
