As shown in FIGS. 2 and 3, the left and right side walls of the coin tube main body 4, which is made up of a plurality of coin storage tubes 8 each having an opening 8a for coin replenishment formed in the upper end thereof, are integrally arranged in parallel. A pair of bosses 9 and 10 are protruded from the bottom side. Here, the upper boss 9 is provided closer to the rear. The lower boss 10 is provided closer to the front.

Further, the coin tube main body 4 is attached to the left and right side walls of the housing 1a of the coin mechanism 1.
The bosses 9 and 10 are attached to the
Insertion grooves 11 and 12 are cut out to fit into each other, respectively. These fitting grooves 11 and 12 are different from the conventional one shown in FIG. 6 in that they are continuous slits cut out in the side wall from the front to the groove diameter. Lower boss 10
As shown in FIG. 4, the fitting groove 12 that fits into the coin tube body 4 is provided with a fitting recess 12a cut out downward and which serves as a pivot point for the coin tube main body 4 during attachment and detachment.

Further, the fitting groove 11 that fits with the boss 9 on the upper side is cut out in a slightly gentle downward arc, and a fitting recess 11a is provided at the rear end, and the coin tube main body 4
When the boss 9 is mounted in the fixed position of the mounting portion 5, the boss 9 is fitted into the fitting recess 11a.

Further, at the substantially center bottom in the front-rear direction of the insertion groove 11, there is provided a groove for tilting and holding the coin tube main body 4 in the first locking state, which is the state in which coins can be refilled, as shown by the dashed line in FIG. A first stopper piece I3 is provided in a protruding manner. The distance X between the upper end of this stopper piece 13 and the tapered portion 11b that is cut out with an inclination downward is formed to be slightly larger than the diameter of the boss 9. The distance y from the operation panel 6 is slightly larger than this distance X. Thereby, the boss 10 can be smoothly rotated to the second locked state, which will be described later, without falling out of the fitting recess 12a. Note that the stopper piece 13 may be provided only in one of the left and right fitting grooves 11.

In addition, when the boss 9 is in contact with the rear part of the stopper piece 13 and the coin tube body 4 is tilted and held in the first locked state, the coin tube body 4 is held against the front surface of the operation panel 6.
The rear end of the upper opening 8a is located at the rear by a slight distance Z, and when coins are refilled into the coin storage tube 8 from the opening 8a, the coins hit the operation panel 6 and prevent the coin tube body 4 from collapsing. It is possible to prevent coins from falling into the rear mounting section 5.

Further, the core-in tube main body 4 further rotates and the boss 9 comes into contact with the bottom of the insertion groove 11 near the front end.
As shown in FIG. 5, a second stopper piece 14 is provided to hold the coin tube main body 4 tilted in the second locked state, which is the state before removal. In this state, the handle 1 provided on the upper back side of the coin tube body 4
5 can be easily pulled out and the handle 15 can be grasped, and if the coin tube main body 4 is further rotated and pulled out as shown in FIG. It can be removed from the housing 1a of the coin mechanism 1.
