[0002]

2. Description of the Related Art As schematically shown in FIG.
Conventionally, a small and lightweight drop-type coin selector 99 having a thick plate shape as a whole has a large rectangular substrate 98.
An opening 96 into which the liquid is injected is appropriately formed.
The opening 96 for inserting the coin 97 is formed in consideration of the outer diameter and thickness of a specific coin, for example, a 100 yen coin. First, the movement of the coin 97 that is thrown into the opening 96 and falls under its own weight is slightly suppressed by a swingable limit lever 94 shown by a small triangular shape on the right side in FIG. After that, the outer diameter of the coin 97 is precisely checked by the semicircular guide pin 95 shown in the center of FIG. 4 and the rotatable, substantially F-shaped cradle 93, while the genuine coin 97 is As shown by the chain line arrow at the center, the genuine coin is sent out in the direction of the passage 92 of the genuine coin by the guide pin 95 and the rotating cradle 93.

Here, the description will be further added.
8 is provided at the upper edge thereof with a pivot 89 at the right end in FIG.
A long lever 88 for cancellation in the form of a letter is rotatably arranged. Reference numeral 87 on the right side of FIG. 4 denotes an L-shaped spring, and the lever 88 is maintained at the position indicated by the solid line in FIG. A pivot 86 substantially at the center of the upper edge of the substrate 98
Has a long Z-shaped wiper 85 rotatably mounted. A long hole 84 formed at the upper end of the wiper 85
Has a pin 83 formed at the left end of the cancel lever 88 movably inserted therein.

[0004] A slightly small rectangular door plate 79 at the center of FIG. 4 is provided so as to be able to freely contact with and separate from the substrate 98, that is, to open and close by a long pivot 78 near the upper edge of the substrate 98. . The door plate 79 is usually moved by a spring 77 with respect to the substrate 98 as shown by the solid line in FIG.
Closed almost parallel. The small triangular lever 94 for limiting the falling coins 97 as described above.
Is rotatably pivoted at the upper center of the door plate 79, and the lower end 72 thereof is bent and inserted movably into the window hole 71 of the door plate 79. In other words, the lower end 72 protrudes toward the substrate 98. A slightly long F-shaped cradle 93 at the center of FIG. 4 is rotatably pivoted 76 to the upper left of the door plate 79. A guide pin 95 is formed at an end of the pivot 76 near the substrate 98.

[0005] In the center of FIG. 4, reference numeral 75 denotes a large arc-shaped long hole.
The coin holding piece 74 is opened from the center of the door plate 79 to the lower left, and the right end of the cradle 93 is bent.
Is movably inserted. In other words, the holding piece 7
4 protrudes in the direction of the substrate 98. A weight corresponding to the correct coin 97 is formed on the left end of the cradle 93. Accordingly, the cradle 93 is normally located at the position indicated by the solid line in FIG. 4 by the upper end of the slot 75, and when the correct coin 97 is held between the guide pin 95 and the holding piece 74, the weight of the coin 97 causes The cradle 93 rotates clockwise in FIG. 4 to send out the correct coin 97 in the direction of the passage 92.

In the conventional example having the above-described configuration,
When a coin 97 having a slightly larger outer diameter than a 100-yen coin, for example, a coin 97 such as a 10-yen coin, is inserted through the opening 96, the coin 97 is carried by the guide pins 95 and the holding pieces 74 of the cradle 93. But passage 9
2 may be blocked and remain in the passage 50 formed between the door plate 79 and the substrate 98. In this case, the canceling lever 88 is pushed against the resilience of the spring 87 by a chain arrow 6 shown in FIGS.
9, the wiper 85 rotates downward to clear the passage as shown by the chain line in FIG. 4, and the operating piece formed to be suspended substantially at the center of the lever 88 as shown by the chain line in FIG. 68 is a bent piece 67 which is an upper corner of the door plate 94.
, The door plate 94 is pushed open against the spring 78. Therefore, the coin 97 having a slightly larger outer diameter is dropped below the door plate 79 and guided to a return passage (not shown).

Further, for example, when an iron yuin 97 having the same size as a 100-yen coin is inserted into the opening 96, the coin 97 is held by the guide pins 95 and the cradle 93, and the coin 97 is While being guided in the direction, it is attracted by the bar magnet 65 erected at the center of the substrate 98 and is guided out of the genuine passage 92, so that the door plate 79
It is thrown downward and is led to a return passage (not shown). The wiper 85 is for wiping out pseudo coins and the like attracted by the bar magnet 65.

[0008]

However, as described above,
In the conventional coin sorting apparatus, there is a problem that the pseudo coin also operates as a genuine coin. Specifically, for example, there is a fraudulent coin in which a thin tape is wrapped around the outer circumference of a 5-yen coin to make the outer diameter resemble a 100-yen coin. In the case of such a fraudulent coin, in the conventional 100 yen coin sorting device,
There is a problem that the same operation as a genuine coin is performed. The present invention has been developed for the purpose of solving the above-mentioned problems. That is, an object of the present invention is to provide a disc sorting apparatus capable of easily removing illegal coins by adding a simple configuration. In other words, an object of the present invention is to provide a disc discriminating apparatus that can easily remove illegal coins using, for example, 5-yen coins.

[0009]

According to the present invention, there is provided at least a substrate (12) having a rectangular plate shape and having a guide hole (14) at a right upper corner of a top edge for receiving a disc body. Of this guide hole

A door plate 16 on the right side of FIG. 1 is a substantially rectangular slightly small door plate, and can be freely moved toward and away from the substrate 12 as shown in FIG. In other words, it is provided to be freely opened and closed. The door plate 16 is normally closed substantially parallel to the substrate 12 by a spring 18 as shown by a solid line in FIG.
A passage 19 for the disk 13 is formed. 20 above the door plate 16 is a small triangular lever, which
This is for limiting the outer diameter of the disc body 13 from which the disc falls. The lever 20 is rotatably pivoted at the center of the upper edge of the door plate 16 and its lower end 22 is bent,
The door plate 16 is movably inserted into the substantially central window hole 10, and its lower end 22 projects into the passage 19. An upper left portion 23 of the door plate 16 is a cradle that is slightly F-shaped in longitudinal direction. The cradle 23 is rotatably pivoted to the door plate 16.

In FIG. 1, a substantially arc-shaped slightly long hole 25 is opened from the center of the door plate 16 to the lower left, and a holding piece 26 of the disk 13 whose right end of the cradle 23 is bent. Is movably inserted. Accordingly, the holding piece 26 projects into the passage 19 as shown in FIG. At the left end of the cradle 23, a weight 27 corresponding to the specific disk 13 is formed. Reference numeral 28 shown in the upper part of FIG. 1 near the pivot 24 is a small ball for cancellation, which is made of iron, steel or the like. As shown in FIG. 3, the ball 28 is housed slidably in a tubular portion 29 coupled above the plastic substrate 12. In addition, the inner end side of the cylindrical portion 29,
That is, a thin ring 30 for retaining the ball 28 is formed on the inner wall near the door plate 16.

On the outer end side of the cylindrical portion 29, a stopper piece of the ball 28, which is not shown in the drawing and is coupled to the substrate 12, is formed. Therefore, the ball 28 is
Of course, the stopper piece can be raised and stored against its elasticity for insertion into the inside. In addition, ball 2
Needless to say, 8 may be a columnar shape having a hemispherical surface at each end. A small longitudinal C-shaped 41 at the upper center of FIG. 1 is a hook means for catching a pseudo coin. The hook means 41 is rotatably mounted on the pivot 17 at an upper position as shown in FIG. The hook means 41 has a weight 42 at the upper end, the lower part 43 is bent, and the tip of the lower part 43 is further bent to form a hook end 44.

The hook end 44 is inserted through a small elongated hole 45 formed in the center of the door plate 16 so as to be freely penetrable. A hook means 41 rotatable about the pivot 17;
In FIG. 2, although the counterclockwise rotation is caused by the weight 42, the bent lower portion 43
The whole is stationary, contacting the lower part of. At this time, the tip of the hook end 44 exists in the elongated hole 45 as shown in FIG. Therefore, cradle 23
When the holding piece 26 moves downward as indicated by a chain line in FIG.
Is released, and the hook means 41 rotates slightly, and the lower part 4
3 comes into contact with the wall of the long hole 45. As a result, the hook end 44 is connected to the passage 19 as shown by a chain line in FIG.
Will protrude inward.

Although the above-mentioned hook means is not shown in the drawings, the hook means can penetrate a small elongated hole 45 so long as the cradle 23 has a hook end 44 protruding into the passage 19 when rotated. The good thing is, of course. In the present embodiment having the above-described configuration, when a specific correct disc body 13 such as a 100-yen coin is inserted from the opening 15, the disc body 13 is
Passage 19 formed by substrate 12 and door plate 16
Will pass through. Disc 13 passing through passage 19
First, the falling movement is slightly suppressed by the swingable outer diameter limit lever 20. Next, the outer diameter of the disc body 13 is precisely checked by the pivot 24 which is also a guide pin and the holding piece 26 of the rotatable cradle 23, and the cradle 23 is weighted by the weight of the disc body 13. As a result, the genuine disc 13 is sent out to a predetermined correct path 33 of the disc 13 as shown by the chain arrow 32 in FIG.

When the disk 34 having an outer diameter slightly larger than the specific disk 13 is, for example, a 25 cent coin,
The disc 34 is prevented from falling by the pivot 24 and the lower end 22 of the limit lever 20, and remains in the passage 19. In this case, ball 2 for cancellation
8 is pressed against the elasticity of the spring 18 from any direction of the arrow on the right side of FIG.
The ball 28 will move to the left. From this, it is sufficient that the ball 28 is a slide having a hemispherical surface. When the ball 28 is pushed and moves to the left in FIG. 3, the door plate 16 is pushed open against the spring 18 via the projecting piece 35 formed at the upper corner of the door plate 16. As a result, the disk body 34 having a large outer diameter is released from being held by the cradle 23, falls below the door plate 16, and is guided to a return passage (not shown).

When an iron disk 35 having the same size as the correct disk 13 is inserted into the opening 15, the disk 3
5 is held by the cradle 23 and heads in the direction of the correct sorting path 33, but is attracted by the bar magnet 36 which stands up below the center of the substrate 12. As a result, the iron disk body 35 is guided outside the correct sorting passage 33 as shown by a chain line in FIG. 1 and is guided to a return passage (not shown). A coin imitated to a specific correct disc body 13, for example, an illegal disc body 40 having a thin cellophane tape wrapped around the periphery of a 5-yen coin to make the outer diameter resemble a 100-yen coin (FIG. 1, In the case of FIG. 2), as in the case of the correct disc 13, it is about to be carried by the pivot 24 and the holding piece 26 of the cradle 23. However,
With the rotation of the cradle 23, the holding piece 26 moves downward, the bent portion 43 of the hook means 41 is released, and the hook means 41 rotates, so that the hook end 44 is shown by a chain line in FIG. Then, it is projected into the passage 19.

As a result, the hook end 44 penetrates through the hole 39 of the disc body 40, and is formed between the door plate 16 and the substrate 12, as shown in FIGS. Will remain in the passage 19. Also in this case, when the ball 28 is moved to the left as shown in FIG. 3, the door plate 16 is pushed and opened against the spring 18, and the hook means 41 is also centered on the pivot 17, although not shown. Then, it is rotated clockwise in FIG. Accordingly, the hook end 44 is disengaged from the hole 39, and the disc body 40 is free, and as a result, falls below the door plate 16 and is guided to a return passage (not shown). In addition, hole 3
In the case of a disc body having no 9, for example, disc body 13,
Although the hook end 44 projects into the passage 19, the hole 39
Of course, the vehicle passes through the passage 19 without being caught.
