According to the coin sorting device 1 described above, not only the coins jammed inside the device,
For a plurality of coins clogged at the entrance portion of the coin slot 9 as shown in FIG. 10, the gate lever 15 is forcibly rotated clockwise to expand the gate plate 3 so that the coin D of FIG. Can be dropped like.

However, when coins jammed in the entrance portion of the coin insertion slot 9 fall at a time, the coins fall in the thickness direction while overlapping as shown in FIG. 11 showing the BB conceptual cross-sectional view of FIG. Therefore, there is a problem that the bent portion 19a of the return passage 19 cannot be passed and a coin jam occurs again at this portion.

The bent portion 19a of the return passage 19
Has a plurality of liquid guide grooves (not shown) formed therein, and the liquid such as a detergent poured into the coin slot 9 is disposed below the liquid guide grooves through the liquid guide grooves. You will be guided to the liquid collection unit.

Further, in recent years, in order to prevent equipment such as vending machines from being installed on a road such as a sidewalk, it is required to make such equipment thinner in the depth direction. Even for a coin sorter installed in such a device, further thinning is required in the depth direction.

That is, in the above-described conventional coin sorting apparatus 1, since the distance in the depth direction when the gate plate 3 is expanded cannot be set long, the return passage when the gate plate 3 is expanded. When a plurality of coins are overlapped and jammed at the bent portion 19a of 19, the jammed coin cannot be removed only by operating the gate lever 15, and the function of the coin sorter 1 itself may be stopped. was there.

In view of the above-mentioned circumstances, it is an object of the present invention to provide a coin sorter capable of promptly and reliably paying out coins stuck in the return passage.

[0025]

In order to solve the above-mentioned problems, a coin sorting device according to the present invention comprises a main plate which constitutes the main body of the device, a gate plate which covers the upper part of the main plate in an openable and closable manner, It has at least a coin passage formed between the main plate and the gate plate and guiding the coin inserted from the coin insertion slot, and the coin stuck in this coin passage is removed by opening and closing the gate plate. In the coin sorting device described above, a step portion is provided on the side of the main plate below the coin passage, which collides with a part of at least one coin among a plurality of coins that have dropped in the thickness direction. To do.

[0026]

According to the coin sorter described above, when a plurality of coins jammed near the entrance of the coin slot is dropped by expanding the gate plate, the jammed coins fall in the thickness direction. However, since a part of at least one of the coins collides with the step portion and the overlapping of the coins is broken, the coins drop one by one below the coin passage.

Therefore, since a plurality of coins do not drop at a time in a bent portion below the coin passage while overlapping, the coins drop one by one, so that the coins can be easily passed. .

Further, between the lower part of the main plate 22 and the front cover 4 covering this lower part, a plurality of coin passages for selecting inserted coins (not shown) and a plurality of coins for inserting inserted coins are selected as in the conventional case. A plurality of coin allocating levers (not shown) for allocating to the passage are provided. further,
Between the above-mentioned main plate 22 and the gate plate 3 that covers the upper part of the coin plate, the coin insertion slot 9 and the coins inserted from the coin insertion slot 9 are guided in the lower right corner in the same manner as in the conventional case. A first coin passage 5 that is inclined in the direction is formed. A return passage 19 is formed below the first coin passage 5 as in the conventional case.

On the other hand, in the coin sorting apparatus 21 of this embodiment, in order to eliminate the jam of coins in the return passage 19,
Stepped portion 2 for colliding the edge portion of at least one of the plurality of coins that have fallen in the thickness direction
5 is formed below the first coin passage 5.

Next, the step 25 formed inside the coin sorting device 21 will be described.

FIG. 2 is a conceptual cross-sectional view of CC in FIG. 1, showing a state where the gate plate 3 is closed (in use).

The above-mentioned step portion 25 is provided upstream of the bent portion 19a of the return passage 19 as shown in FIG. 2 and constitutes the left side surface of the first coin passage 5 of the main plate 22.
Is formed integrally with. Further, this step portion 25 is shown in FIG.
As shown in FIG. 5, the main plate 22 is formed along the wall surface of the main plate 22 so as to be inclined in the lower right direction in the drawing. The step 25
The protruding length of the upper end 25a of the is set appropriately according to the thickness of the inserted coin.

Next, the operation of the step portion 25 when a plurality of coins stuck in the coin slot 9 are dropped will be described.

Now, assume that a plurality of coins E, F, and G are packed in the entrance portion of the coin insertion slot 9 as shown in FIG. Here, when the user forcibly rotates the gate lever 15 in the clockwise direction, the gate plate 3 and the housing 10 are opened, and the coin slot 9 and the first coin passage 5 are opened.
All the bottom surface of is opened. Then, as shown in FIG. 3, the coins E, F, and G fall to the bottom surface of the opened first coin passage 5. At this time, if the coin F and the coin G overlap and fall in the thickness direction, the edge of the coin F passing through the main plate 22 side of the two coins collides with the upper end 25a of the step 25. The overlap of the two coins will be destroyed. According to this, 2
One coin does not drop at a time from the stepped portion 25 while being overlapped with each other.
The coin G first passes through 9a, and then the step 25
The coin F that collides with and the coin E that collides with the gate rail 20 pass through the bent portion 19a in this order.

Therefore, even when the gate plate 3 cannot be sufficiently expanded in the depth direction due to external conditions, at least one of the plurality of coins falling in the thickness direction is dropped. Since the rim and the step portion 25 collide with each other to collapse the coin overlap, the return passage 1
The coins pass through the bent portion 19a of 9 one by one, and the occurrence of jamming of coins at this portion can be prevented.
