DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko / slot machine and an arrangement game, for opening / closing a gate in a predetermined time zone such as a parking lot, for a traffic ticket, or in a company or a park. The present invention relates to an ID medal that can be used for pseudo coins that can be distributed only in a specific area.

[0002]

2. Description of the Related Art Conventionally, special medals have been used for such purposes. For example, in a pachinko parlor, a game medal of a metal disk having a diameter of 25 mm and a thickness of 1.6 mm is used, and the medal is borrowed by a number corresponding to a payment amount and the medal is inserted to play the game. The device can be operated and can be exchanged for a prize according to the number of medals remaining after the game. This medal is fixed to the above-mentioned shape and size in any game machine used in any pachinko parlor.
Therefore, a mark or the like unique to each store is integrally formed in a swollen shape on the medal so that it can be distinguished from other stores.

[0003]

However, as described above, the medals used in all pachinko parlors are fixed in shape and size, so that even if medals from other parlors are inserted, the amusement equipment operates normally. In addition to the above, the medal counting device for exchanging the remaining medals for prizes also counts medals from other stores mixed in medals to be counted. In addition, it is almost impossible for a clerk to visually find a medal of another store by the medal identification mark during a game or counting. Further, it is impossible to select medals of other stores before opening or after closing due to the lack of means other than visual determination and the large number of medals. As a result, the rent of medals paid to other stores will also be borne, and if medals from other stores are brought in in large quantities or frequently, damage may increase and management may become difficult. Invite you.

Accordingly, the present invention provides an ID code that can be used to identify illegally used medals by using a simple automatic detection means to accurately identify whether the medals are authentic or not when inserted into a game machine or the like. It is an object of the present invention to provide a provided ID medal.

[0005]

[MEANS FOR SOLVING THE PROBLEMS] To solve the above technical problems.
Therefore, the ID medal of the present invention has a flat disk shape.
Medal body and at least one of the medal body
On the surface side, make concentric circles with the outer circumference circle.
And a plurality of annular projections each having a different diameter.
Unique based on the number of annular ridges and the spacing between annular ridges
ID medal in which the ID code of
Central part of the medal body where no convex part is formed
Has a unique identification mark that can be visually identified.
Is characterized by that.

[0006] Also, the annular convex portion has a maximum diameter.
The height of the annular projection from the surface of the medal body is
And larger than the height of the convex part,
The ID code may be formed by the annular convex portion excluding the annular convex portion having the largest diameter .

Further, the width of each of the annular projections is set to
Than the width of the annular groove formed between the adjacent annular protrusions
It is preferable to make it small. Furthermore, the annular convex
Each side peripheral surface part of the part has a certain inclination angle
It can also be a light reflecting surface.

[0008] Then, it is also a benzalkonium form a unique ID code is different from the width of the annular protrusion in a plurality of types.

[0009]

[Function] An identification mark provided at the center of the medal body
This allows visual identification of illegally used medals.
Can be done. On the other hand, at an arbitrary position on the passing locus line of the center of the medal in the medal passage of the device using the medal,
If an optical detecting means for detecting the annular convex portion from the reflected light amount of the projected light by the medal is arranged, even if the medal moves in the passage in any state such as rolling or sliding, the annular shape can be obtained.
The number of protrusions and the interval between the annular protrusions are accurately detected ,
The medals used fraudulently from the medal unique ID code read by the detection signal of that can be selected automatically.

The ring having the largest diameter among the ring-shaped protrusions
Adjust the height of the convex part from the surface of the medal body to the other circular convex part.
If the ID code is formed by an annular convex portion excluding the annular convex portion having the maximum diameter, the ID is detected first and last for each annular convex portion.
Since a signal having a large signal level by the annular convex portion having the maximum diameter can be used as a reading start code and a reading end code, the reading accuracy of the ID code is improved. In addition, when the medal is thrown into the device to be used and moves in the guide passage, a portion sliding on the guide wall of the guide passage on the formation surface of each annular convex portion of the medal has a maximum diameter.
It has become only the end face of the annular projection, the damage and wear of the ring-shaped convex portions for forming the ID code can be prevented for a long time.

Further, the width of each of the annular convex portions is set to
If it is formed smaller than the width of the annular groove formed between the annular convex portion and the annular convex portion, the ID code can be forged by cutting the end face of the annular convex portion with a sharp object to form the annular convex portion. Can be prevented . In addition, since the width of the annular groove is wide, the width of the protrusion for forming the annular groove in the press die when the medal is manufactured by press working can be widened, and the deformation of the protrusion is reduced, and the press die is reduced. Life can be extended.

Furthermore , each side peripheral surface of the annular convex portion
Minute, if the light reflecting surface having a constant slope angle, as medals for game equipment, in which a relatively thin is defined can not be increased height from the medal body surface of the annular protrusion thickness, optical detection means, and projected from an oblique be configured to receive a thickness direction of medals, reliably annular projection and receives reflected light from a relatively wide light reflecting surface reflecting the area of the annular projection Can be detected.

[0013] Then, if the shape forming a unique ID code is different from the width of the annular convex portion to a plurality of types, it is possible to increase the types of ID code.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. 1A and 1B are a plan view of a first embodiment of the present invention and a cross-sectional view taken along the line AA of FIG. 1A, respectively. Four annular projections (2) to (5) which are concentric with the outer peripheral circle and have different diameters on both surfaces of the medal body (1) formed into a flat disk shape by metal or synthetic resin or the like. Are formed respectively in plane symmetry. In this embodiment, the case where the annular convex portions (2) to (5) are arranged at the same interval is illustrated, but the number of the annular convex portions (2) to (5) and the mutual interval are set. By changing the arrangement, a unique ID code is formed.
In the center of the medal body (1), a unique identification mark (6) similar to an existing one that can be visually distinguished is provided. In this medal, a unique ID code formed by each of the annular convex portions (2) to (5) is integrally formed on the medal body (1), so that the identification mark (6) is formed integrally with the bulge. For example, it may be provided by means for attaching a seal or the like. In addition, the width (d) of each of the annular projections (2) to (5) is set between the two adjacent annular projections (2) to (5). Is smaller than the width (D).

When this medal is inserted into a slot of an adaptive device such as a game device, a pair of guide rails (13) having a U-shaped cross section as shown in FIG. As shown by the dashed line, the light passes through a guide passage formed so as to face in parallel at substantially the same interval as the diameter of the medal, but from the amount of reflected light by the medal of the projected light, the annular convex portions (2) to ( 5) Optical detection means (not shown) for detecting
If the medals are arranged at an arbitrary position on the passing trajectory line of the center of the medal in the guide path as shown by a one-dot chain line in FIG. 1A, the medal may be rolled or slid in any state. Even when moving in the guide passage, each annular convex portion (2) to
Since (5) is arranged concentrically, the number of each annular convex portion (2) to (5) and each annular convex portion (2) to (5)
Each interval of (5), that is, the width of the annular groove (7) can be accurately detected.
The D code can be determined. Further, since the medal is also provided with an identification mark (6) that can be visually distinguished, there is an advantage that a meticulous user can be visually distinguished and selected before use. In this embodiment, since the annular convex portions (2) to (5) are formed symmetrically on both surfaces of the medal body (1), the optical detecting means is disposed on one side of the guide passage. Only when the medal is inserted, the directionality is lost.

In the medal, an identification mark (5) is provided at a central portion of the medal body (1), and each annular projection (2) is provided.
Since (5) is formed closer to the outer periphery, the radius of each of the annular projections (2) to (5) can be made larger, so that the curvature (the reciprocal of the radius of curvature) becomes smaller, and the light reflection area becomes larger. As the amount of light received by the optical detection means increases and the light reflection angle decreases, there is an advantage that even if the reading point of the optical detection means slightly deviates from the diameter line of the medal, there is almost no effect. Since the identification mark (5) only needs to be visually distinguishable, the identification mark (5) is not limited to the above-described central portion, but may be applied to the outer peripheral portion or a part of the annular convex portions (2) to (5) by printing means or the like. Good.

FIG. 2 is a sectional view taken along a line passing through the center in the second embodiment of the present invention. The difference from the first embodiment is that only one surface of the medal body (8) is annularly convex. part (9) - to form a (12), these annular projection (9) to <br/> annular projection located on the maximum diameter, i.e. outermost of (12) (9) medals body (8) the height from the surface of the formed larger than the other ring-shaped convex portion (10) to (12),
The only configuration is that an ID code is formed by these annular convex portions (10) to (12).

[0018] In FIG. 3 showing the signal detected by the optical detection means ring-shaped convex portions of the medal (9) to (12), each annular protrusion (9) - (12) relative to the beginning and end respectively detected be that the detection signal of the ring-shaped convex portion (9) (S1), ( S3)
Since the signal level becomes higher becomes larger with light reflecting surface is large height from the surface of the medal body (8), it is possible to identify with other signals, this detection signal (S
1) and (S3) are used as a read start code and a read end code, respectively. Therefore, the I based on the detection signal (S2) of each of the other annular convex portions (10) to (12).
The reading accuracy of the D code is remarkably improved.

As shown in FIG. 4, when the medal moves in a guide passage formed by facing a pair of guide rails (13) having a U-shaped cross section, each annular convex portion (9) of the medal is moved. The part sliding on the inner wall surface of the guide rail (13) of the guide passage on the formation surface of (12) is only the end face of the specific annular projection (9), and each annular projection for forming the ID code. Damage and wear of the parts (10) to (12) can be prevented for a long time. In addition, although it has a simplified shape in which annular convex portions (9) to (12) are formed only on one surface of the medal body (8), as shown in FIG. ), There is no direction in inserting medals.

FIG. 5 is a sectional view taken along a line passing through the center in a third embodiment of the present invention. In FIG. 5, the same components as those in the second embodiment are denoted by the same reference numerals. ,
The points of difference, the annular projection of the order to you form an ID code (15) to (17), each of the width (d1) - (d3) is only configured with a shape different from each other.

[0021] Thus, the annular projection of the order to you form an ID code (15) to the number of (17), each annular protrusion (15)
(17) The width of the annular groove (7), which is the distance between each other, and the width (d1) to (d) of each of the annular protrusions (15) to (17).
Since the unique ID code can be formed by the three types of elements 3), the types of ID codes can be greatly increased.

In each of the first to third embodiments, as shown in FIGS. 1B, 2 and 5, each of the annular projections (2) to (5), (9)-
(12), widths (d) and (d1) of (15) to (17)
By forming (d3) smaller than the width (D) of the annular groove (7), the following effects can be obtained. If the width of the annular protrusion (T) is formed to be larger than the width of the annular groove (M) as shown in FIG. 6A, a press die ( K) has a shape in which the width of the protrusion (R) for forming the annular groove (M) is small, and the protrusion (R) is formed during processing.
This causes a problem that the life of the press die (K) is shortened due to bending or bending deformation. On the other hand, when the shape is the same as that of each of the first to third embodiments, since the width of the annular groove (7) is relatively large, the press die has a shape having a large protrusion, and the above problem is caused. Does not occur. When the width of the annular convex portion (T) is large, as shown in FIG.
There is a possibility that the ID code may be forged by a member (H) such as a blade having a sharp tip to separate the end face of the annular projection (T) into two annular projections having a small width. In contrast, in the present invention, each of the annular convex portions (2) to (5), (9) to (1)
2), widths (d) of (15) to (17), (d1) to (d)
Since 3) is small, it is impossible to forge the ID code by cutting.

FIGS. 7A to 7C show the fourth embodiment of the present invention.
Various modifications of the embodiment are shown. In each case, light reflecting surfaces (18a) to (20a) having a fixed inclination angle are formed on the side surfaces of each of the annular projections (18) to (20). These light reflecting surfaces (18a) to (20a)
The light is projected at an angle at which light projected from a predetermined angle is reflected in a direction orthogonal to both surfaces of the medal, that is, in a thickness direction.

In a medal for a game machine having a relatively small thickness, such as a medal for amusement equipment, a medal body table having an annular convex portion is provided.
Can not increase the height from the surface, because the difference of unevenness of the annular groove an annular protrusion becomes smaller, the forming surface of the annular projection, when projecting the light from the orthogonal direction to the forming surface, the annular projection It reflected light receiving of the annular groove as well reflected light from part
In addition, since the difference between the two reflected light amounts is small, it is difficult to detect the annular convex portion. Therefore, as described above, the light reflecting surfaces (18a) to (20a) are provided on the side surface portions of the respective annular convex portions (18) to (20), and the light reflecting surfaces (18) to (20a) are provided.
a) to (20a) are projected at an oblique angle that reflects light in a direction orthogonal to both surfaces of the medal, so that the light reflecting surface (1) is projected.
Since only the reflected light from 8a) to (20a) can be received and the light reflection area can be set large, the annular convex portion (18)
The detection accuracy of (20) is improved in each stage, and accurate detection can be performed.

As described above, the ID medal of the present invention
According to the above, a medal body having a flat disk shape,
