Therefore, dirt on the base portion due to coins is easily removed by opening and cleaning the base portion. be able to. In addition, by opening the base portion, coins in the coin holding tube can be taken out from below the tube, and the retrievability of coins is improved. (F) Example Hereinafter, an example of the present invention will be described in detail with reference to the drawings. 1 and 2 show a side view and a rear view of a cassette type coin tube according to an embodiment of the present invention. In FIGS. 1 and 2, the coin tube main body 1 is composed of a plurality of coin holding tubes 2 having openings at upper and lower ends, and coins of different denominations are held. These tubes 2 are juxtaposed and formed integrally. At the lower part of the coin tube body 1, there is provided a coin receiving stand 4 which can be freely opened and closed with a pair of left and right pins 3, 3 attached to the lower part on both sides near the front. The coin receiving tray 4 can store a predetermined number of coins M. Locking pieces 5a, 6a are provided on the left and right sides of the back side of the coin receiver 4.
A pair of hooks 5 and 6 with
Is attached. As shown in FIG. 3, a pair of left and right hook levers 7, 8 having substantially L-shaped engaging pieces 7a, 8a facing outward are provided at the lower rear portion of the coin tube body 1, as shown in FIG. It is attached using leaf spring washers 9, 10, and the like. Locking pieces 7a, 8a of these hook levers 7, 8 made of an elastic member
Is engaged with the locking pieces 5a, 6a of the hooks 5, 6, respectively, so that the coin receiver 4 can be normally kept closed. When the coin receiving tray 4 is opened, the hook levers 7, 8 of the elastic member are pushed inward as shown by arrows in FIG. 2 to release the engagement with the hooks 5, 6. Since the coin base 4 is provided at the lower portion of the coin tube main body 1 so that the entire base can be freely opened and closed, dirt on the base part due to coins can be easily cleaned by opening the coin base 4. In addition, by providing the coin receiving tray 4, coins can be taken out from the lower side of the coin tube main body 1, so that the retrievability of coins is improved, and the required amount of coins in the coin holding tube 2 can be taken out freely. Can be. By the way, an opening 11 for dispensing change is formed below the coin holding tube 2 at a lower rear portion of the coin receiver 4, and a change dispensing mechanism can be operated at the bottom of the coin receiver 4. Groove 12 is formed in the front-rear direction. When paying out the coins held in the coin tube main body 1, a change payout plate shown in FIG.
13 is reciprocated in the direction of the arrow using the driving force of a gear motor or a solenoid plunger, etc.
The coin located at the lowermost part of the coin receiving tray 4 can be pushed out by the change dispensing plate 13 and can be dispensed from the opening 11 having a height of approximately one coin. Next, a coin detecting mechanism for detecting whether or not a predetermined number of coins are held in the coin receiving tray 4 will be described with reference to FIG. 4 to FIG. Here, the predetermined number is, for example, in the case of setting the price in increments of 10 yen, if the change amount of at least 90 yen is left in the coin receiving tray 4 with respect to the insertion of 100 yen, the next sales state can be prepared. Therefore, it corresponds to at least 9 of the minimum change number. It is sufficient that the coin receiving tray 4 can store a slightly larger number of coins than the minimum change number. 4 and 5, the coin tube main body 1
On the rear wall surface of the coin rest 4 closed at the bottom of
Through holes 21 are formed at coin holding positions corresponding to the predetermined number of coins. Further, the slider 22 approaches or retreats in the direction of the plurality of coin holding tubes 2 arranged in parallel by the action of a rotor 30 that converts the rotational motion of a gear motor (not shown) into a linear motion, for example. The driving force of the rotor 30 is transmitted to the change dispensing plate 13 via the connecting member 31. The detecting member 25 is a through hole 21 formed in the wall surface of the coin receiving tray 4.
Through the coin receiving tray 4, the detecting member 25 has a slider 22 as shown in FIG.
And is supported by a spring 23. The slider 22 includes a silicone rubber 24 that is deformed in a direction in which a spring 23 is compressed. A conductive rubber 27 is mounted on the silicone rubber 24 and a slider facing the conductive rubber 27.
The limit switch 26 is formed by mounting a gold plating pattern 28 on the inner wall 32 of the 22. This silicone rubber 24 is spring
It is set so that it deforms with a pressure weaker than 23.
An operation member 33 of the limit switch detects a state in which the slider 22 is closest to the coin receiving tray 4, and is in contact with an outer wall of the coin receiving tray 4. In the above-described coin detecting mechanism, the slider 22 is separated from the coin receiving tray 4 at the time of standby shown in FIG. 6, and the detecting member 25 is retracted from the inside of the coin receiving tray 4. Accordingly, the spring 23 and the silicon rubber 24 are both extended, and the switch 26 is OFF because the conductive rubber 27 and the gold plating pattern 28 are separated. Then, as shown in FIG. 7, when the slider 22 is moved closer to the coin cradle 4 to detect the presence or absence of change, the detecting member 25 advances into the coin cradle 4.
When a coin is present in the coin receiving tray 4, as shown in FIG. 8, the detecting member 25 comes into contact with the coin, and when the slider 22 approaches the coin receiving tray 4, the silicon rubber 24 is first deformed. The switch 26 is turned on by contact with the gold plating pattern 28. When the slider 22 further approaches the coin tray 4, the spring 23 contracts and absorbs this stroke. However, if there is no coin corresponding to the position where the detection member 25 advances, the switch 26 is
Does not turn on. Then, when the slider 22 comes closest to the coin receiver 4 and the limit switch is turned on by the operation of the operating member 33, the switch 26 is detected to be ON, and the coin receiver 4 is detected.
It is possible to determine the presence or absence of a predetermined number of stored coins in the inside. By determining whether the switch 26 is ON or OFF at the timing when the limit switch is turned ON, the presence or absence of a predetermined number of coins can be accurately detected. Next, a mechanism that makes the coin tube main body 1 detachable from a coin mechanism that performs all operations related to coin processing in a vending machine will be described with reference to FIGS. 9 and 10. FIG. A pair of bosses 14 and 15 are vertically provided on the lower side of both side walls of the coin tube main body 1, respectively. Fitting grooves 17 and 18 are cut out on both side surfaces of the housing of the coin mechanism 16 so that the bosses 14 and 15 of the coin tube main body 1 are fitted into the fitting grooves 17 and 18 or are fitted. By unwinding, the coin tube main body 1 can be detachably attached to the coin mechanism 16. FIG. 10 shows a state in which the coin tube main body 1 is locked by the stopper 17a of the fitting groove 17 in a state immediately before removal. To hold the coin tube body 1 so that it does not come off after being attached to the coin mechanism 16, use the coin mechanism.
A lock lever 19 provided on the coin tube 16 and urged downward by a spring is engaged with a lock pin 20 provided on the coin tube body 1. The coin mechanism 16 has a coin receiving slot 35 at the top,
A coin discriminating unit 36, a change dispensing mechanism unit 37, and the like are provided below. Coin holding tube 2 of coin tube body 1
