[0002] Conventionally, in a game machine such as a vending machine or a slot machine, the authenticity of a disc (coin or a medal for a game) inserted from a disc slot is determined. A disc discriminating apparatus is provided which accommodates disc discs regarded as true disc discs and returns disc discs regarded as pseudo disc discs.

[0003] Fig. 11 is a conceptual front view of a main part of a conventional disc body sorting apparatus 1, and particularly shows the vicinity of a disc body inlet 2.

The disc discriminating apparatus 1 includes a first disc disc guide passage 3 for guiding a disc disc inserted into a disc disc input port 2 downward, and a first disc disc. A second disc guide path 5 is formed by a single inclined transfer rail 4 communicating with the downstream end of the guide passage 3 and guiding the inserted disc body obliquely to the right in the drawing. In FIG. 11, reference numeral 13 denotes a disc body detecting means for measuring the authenticity of the disc body or the number of disc bodies passing therethrough.

[0005] The first and second disc body guide passages 3 and 5 are provided with a main plate 6 and a gate plate for opening and closing the surface of the main plate 6, as shown in FIG. 7 and.

[0006] On the other hand, as shown in FIG. 11, the second disc guide path 5 includes a disc for discriminating the authenticity of the disc by restricting the thickness of the inserted disc. Plate thickness regulating means 8 is provided.

[0007] The conventional thickness control means 8 is constituted by a thickness screw 9 disposed on a main plate 6, as shown in FIG. 13 and FIG. 13 shown in a BB conceptual sectional view of FIG. The screw 9 protrudes from the surface of the main plate 6 into the second disc guide passage 5, thereby forming a gap between the rear surface of the gate plate 7 and the tip of the thickness screw 9. The thickness of the disc falling in the second disc guide passage 5 is regulated. The gap between the tip of the thickness screw 9 and the rear surface of the gate plate 7 facing the same is set to be approximately the same as or slightly wider than the thickness of the round disk, and set to a distance.

[0008] According to such a plate thickness regulating means 8, as shown in Fig. 14, the plate thickness of the inserted disc body 10 is the same as the plate thickness of the true disc body, but if the thickness is smaller than that, After passing through the thickness regulating means 8, it is guided downstream of the second disc body guide passage 5 and is sorted.

On the other hand, as shown in FIG. 15, when the thickness of the inserted disc body 11 is thicker than the thickness of the true disc body, the disc body 11 comes into contact with the tip of the thickness screw 9 of the thickness control means 8. .

[0010] As a result, the disk 11 having a thickness greater than that of the true disk comes into contact with the tip of the thickness screw 9 and stops, thereby restricting the insertion of the disk 11 having a thickness greater than the specified value. You.

[0011] As described above, the disk body 11 having a predetermined thickness or more stopped between the tip of the thickness screw 9 and the back surface of the gate plate 7 expands the gate plate 7 as shown by the arrow D with respect to the main plate 6. Then, the disk body 11 having the specified thickness or more falls downward, is eliminated, and is returned.

[0012] In Figs. 11 and 12, reference numeral 15 is formed in the second disc body guide passage 5, and is a well-known disc body outer diameter selecting means for sorting disc bodies according to their outer diameters. As shown in FIG. 12, the disc outer diameter selecting means 15 includes a notch 7a formed in the gate plate 7 and an inclined surface 7b.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, an embodiment of the disc sorting apparatus according to the present invention will be described in detail.

FIG. 1 is a conceptual front view of a main part of a disc discriminating apparatus 20 according to the present invention, and the same parts as those in FIGS.

[0019] As in the prior art, the disc discriminating apparatus 20 also has a first disc disc guide passage 3 for guiding the disc disc inserted into the disc disc inlet 2 downward, One inclined transfer rail that communicates with the downstream end of the disc guide path 3 and guides the inserted disc obliquely to the right in the drawing. And a second disc body guide passage 5 composed of a screw 4.

[0020] Also, in this disc discriminating apparatus 20, by controlling the thickness of the disc disc which has been inserted,

A disc thickness regulating means 30 for discriminating the authenticity of the disc is provided in the second disc guide passage 5 composed of one inclined transfer rail 4.

On the other hand, in the second disc guide path 5 located downstream of the plate thickness regulating means 30, the discs whose transfer has been prevented by the plate thickness regulating means 30 are guided by the second disc guidance. A disc-shaped traffic blocking means 50 for blocking transfer to the downstream of the passage 5 is provided.

Next, the respective structures of the plate thickness restricting means 30 and the disc body traffic blocking means 50 will be sequentially described in detail.

The plate thickness regulating means 30 of the disc is disposed upstream of the second disc guide passage 5 and is in contact with the inserted disc, and is in contact with the disc. The attitude is changed according to the thickness, and the thickness of the inserted disc body is regulated.The structure is as shown in the CC cross-sectional view of Fig. 1 and as shown in Fig. 2, as shown in Fig. 2. A lever 32 supported rotatably about a shaft 31, an inclined guide 33 supported at the lower end of the lever 32, and the lever 32 are always attached to the shaft 31 in a true counterclockwise direction. And a stopper means 35 for restricting rotation of the inclined guide 33 beyond a certain rotation angle.

The above-described inclined guide 33 is formed on the surface of the main plate 6 which forms one side wall of the second disc guide path 5 as shown in FIG. 3 shown in the DD section of FIG. At the initial position shown in FIGS. 2 and 3, the urging force of the compression panel 34 abuts the inclined surface 7b of the gate plate 7 and stops its movement at the initial position shown in FIGS.

On the other hand, as shown in FIG. 3, the inclined guide 33 of the plate thickness regulating means 30 has a guide portion 33a whose tip is gradually inclined toward the gate plate 7 toward the downstream of the second disc guide passage 5. And a substantially frusto-conical plate-thickness regulating portion 33b supported at the tip of the guide portion 33a. Note that the plate thickness regulating portion 33a is made of metal.

As shown in FIG. 3, the stopper means 35 is disposed at a position facing the plate thickness regulating portion 33b, and the stopper means 35 is, as shown in FIG. It is composed of a thickness screw 9 screwed into the female screw portion 35b supported by the screw.

On the other hand, the disc-shaped traffic blocking means 50 located downstream of the plate thickness regulating means 30 As shown in FIG. 3, a knockout lever 51 having a substantially U-shaped cross section is configured to be able to protrude and retract into the second disc guide passage 5 through a notch 6c formed in the main plate 6.

[0028] The knockout lever 52 is rotatably supported about a shaft 52. Further, the knockout lever 52 is biased by a compression spring 53 so as to always rotate counterclockwise about the shaft 52. Have been.

[0029] A stopper projection 51b protrudes from the tip end 51a of the knockout lever 51 described above. In the initial position in FIG. 3, the projection 51b is engaged with a locking piece 6d formed on the back surface of the main plate 6. Engaged and its rotation has stopped.

Note that an engagement piece 51c is formed on the upper surface of the lock lever 51 to be engaged with a later-described expanding pin used for expanding the gate plate 7.

Next, the operation of the above-described disc body sorting apparatus 20 will be described, and the configuration will be described in more detail.

As shown in FIG. 4, when a disc 60 having a diameter larger than a specified diameter to be sorted is vigorously thrown into the disc inlet 2, the disc 60 becomes the first disc. After passing through the disc-shaped passage 3, it collides with the inclined transfer rail 4 constituting the second disc-shaped passage 5, and thereafter, is directed toward the second disc-shaped passage 5 whose inclination is inclined.

At this time, as shown in FIG. 5 shown by the DD cross section in FIG. 4 and FIG. 6 shown by the CC cross section in FIG. 4, one side surface of the disc body 60 which is vigorously thrown in and violently comes into pressure contact gradually. The gate plate 7 is gradually urged by the urging force of the inclined guide portion 33a, that is, by the urging force of the inclined guide portion 33a of the plate thickness regulating means 30 which is urged by the compression panel 34 (FIG. 2) and slidably supported. Pressing against the side, the rampage, that is, the vibration is absorbed and damped.

After that, when the plate thickness of the input disc body 60 is smaller than the specified plate thickness, as shown in FIG. 5, the inclined guide portion 33a and the plate thickness restricting portion 33b of the plate thickness restricting means 30 Further, it passes through the disc-shaped traffic blocking means 50 and is smoothly guided to the downstream of the second disc-shaped passage 5 and is sorted.

Then, the detection means 13 (FIG. 1) disposed downstream thereof measures the trueness or falseness of the input disc body 60 or the number of passing discs. On the other hand, as shown in FIG. 7 and FIG. 8, even when the disc 70 is vigorously input and the force is larger than the specified diameter and the force is larger than the specified plate thickness, The ramp is gradually pressed against the gate plate 7 side by the biasing force of the inclined guide portion 33a that gradually presses against the side surface of the disk body 70, and the ramp is absorbed.

As described above, the disc 70 thicker than the specified plate thickness in which the runaway has been absorbed is guided to the downstream side of the second disc passage 5 and hits the plate thickness regulating portion 33b of the inclined guide 33. When the contact is made, the plate thickness restricting portion 33b comes into contact with the thickness screw 9 of the stopper means 35, whereby the gap between the plate thickness restricting portion 33b and the back surface of the gate plate 7 is regulated, and the thickness becomes smaller than the specified plate thickness. The progress of the thick disk 70 stops reliably.

[0038] The gap between the thickness regulating portion 33b in contact with the thickness screw 9 and the back surface of the gate plate 7 is formed to be equal to or slightly larger than the thickness of the prescribed disc (true disc). Needless to say,

Therefore, according to the above-described thickness control means 30, even a disc body which is thrown in vigorously and ramps up is absorbed by the inclination guide 33 of the thickness control means 30 which changes the posture described above, and is stable. In this state, the sheet is transferred to the downstream side of the second disc guide path 5.

[0040] On the other hand, as shown in Figs. 7 and 8, when the movement of the disc body 70 having a thickness greater than the specified thickness is stopped by the thickness regulation means 30, the return lever (not shown) is then moved to a return lever (not shown). By operating, the gate plate 7 is expanded with respect to the main plate 6, and the stopped disk body 70 is dropped downward to remove it.

At this time, as shown in FIG. 9, in conjunction with a return lever (not shown), an expanding pin 80 projecting as shown by a dashed line is brought into contact with an engaging piece 51c of the disc-shaped traffic blocking means 50. When they come into contact with each other, the knockout lever 51 rotates clockwise about the shaft 52 via the engaging piece 51c, and the tip end 51a protrudes into the second disc body passage 5.

When the expanding pin 80 comes into contact with the engaging piece 51c of the disc-shaped traffic blocking means 50, the projecting piece 7d of the gate plate 7, which is also in contact with the lower surface of the engaging piece 51c, is indicated by a dashed line. Press and expand the gate plate 7 to the main plate 6 as shown by arrow E.

[0043] As described above, the gate plate 7 is moved to the main plate by the expansion pin 80 linked to the return lever. When the plate is slightly expanded with respect to the gate 6, the gap between the plate thickness regulating portion 33b and the surface of the gate plate 7 slightly opens, so that the disc 70 stopped as in the related art becomes the second disc. At this time, the knock-out lever 51 of the above-described disc-body passage blocking means 50 protrudes into the second disc-body passage 5, as shown in FIG. Since the movement is restricted, the guide is stopped at the position where it cannot be guided downstream of the second disc guide passage 5.

After that, as shown in FIG. 10, the expansion pin 80 further linked to the return lever moves to the second disc guide passage 5 side, whereby the engagement piece of the disc When the gate plate 7 expands with respect to the main plate 6 via 51c, the disk body 70 whose progress is prevented by the knockout lever 51 is formed between the expanded gate plate 7 and the main plate 6. It falls down from the large gap 90 and is surely returned to the disc return port (not shown).

When the return lever (not shown) is returned to the initial position after the return of the disc body 70 is completed, the knockout lever 51 of the disc traffic prevention means 50 is urged by the compression spring 53 of the urging means. The force returns to the initial position in FIG.

In the above-described embodiment, the above-described plate thickness regulating means 30 is constituted by the inclined guide portion 33a for changing the posture. The present invention is not limited to the above-described embodiment, and is a view of a conventional example. As shown in 11, the thickness regulating means 8 constituted only by the thickness screw 9 may be used.
