DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inserted medal detection device, and more particularly to a game machine using medals as a medium.
The present invention relates to a device for detecting insertion of medals.

[0002]

2. Description of the Related Art Conventionally, there have been many medal game machines using medals as a medium. Since such a medal game machine requests a medal insertion as a game start condition, for example, a medal insertion is detected so that the game can be started only when a medal is inserted, and the control unit of the game machine detects the medal insertion. Means to communicate to In many cases, an optical sensor is attached to the medal sorting machine.

A conventionally used means for detecting insertion of a medal will be described in more detail with reference to FIG.
Although not shown, the medal game machine includes a medal insertion slot for inserting medals from outside the medal game machine, and a medal stocker for storing medals inserted from the medal insertion slot in the medal game machine.

From the medal insertion slot to the medal stocker, a medal passage 10 for guiding the inserted medal is provided. The medal path 10 is formed from a path introduction member 12 communicating with the medal insertion port from the medal insertion port toward the medal stocker, and a medal sorting machine 13.

The medal path 10 in the medal selector 13 is
The medal passage middle portion 14 is slightly inclined from the horizontal, and the medal passage rear portion 15 is further continuously inclined to the medal passage middle portion 14. The medal sorter 13 is a member for eliminating insertion of medals other than medals used in the medal game machine. According to the medal selecting machine 13, among the inserted medals, inappropriate medals are discharged out of the medal game machine, and only proper medals are taken into the game machine. The medal sorter 13 having such a function is a detection device for detecting passage of a medal when it is taken into an appropriate medal game machine,
For example, an optical sensor 29 is provided.

The optical sensor 29 transmits a medal to a control unit (not shown) of the game machine only when it detects the passing of a medal so that the game can be started. Some game machines can insert several medals per game, but the light sensor 29 provided in such a game machine causes the control unit of the game machine to count the number of medals. .

Incidentally, in a medal game machine having a so-called credit function capable of crediting inserted medals, if more medals than those used in one game are inserted, one game is played. More medals than used will be credited and can be used for the next game.

[0008]

However, the conventional means for detecting inserted medals has a drawback that it is ineffective against the following illegal acts. That is, once a medal passes the optical sensor, the game start condition is satisfied. For example, a medal with a thread attached thereto is inserted, and after passing the optical sensor, the thread is wound up and the medal is pulled back. There were cases of fraud, such as passing the optical sensor again after the end. By performing such misconduct, it is possible to give a medal game machine the same effect as if a newly inserted medal game machine is used, without imposing a medal after the end of one game. In particular, in a medal game machine capable of inserting several medals per game or a medal game machine having a credit function, the damage caused by such fraud has been great in a short time.

[0009] Fraud related to medal insertion is not limited to the above, and there are various fraudulent means. However, such a fraudulent means cannot be effectively prevented in the conventional medal detection device. . An object of the present invention is to provide an inserted medal detection device that does not allow a game to be started even if an illegal operation is performed when inserting a medal.

[0010]

[0011]

The inserted medal detection device according to the first aspect of the invention has the following operation. A case where a player inserts an appropriate medal into a medal game machine provided with the insertion detection device according to the invention will be described.

The player inserts a medal through the medal insertion slot. The inserted medals are taken into the medal game machine by being guided to the medal passage. Then, the medal sensor located near the medal slot detects the passage of the medal and informs the controller of that fact.

Next, the medal sensor located far from the medal slot detects the passage of the medal and transmits the fact to the control unit. The control unit checks information indicating that the medal sensor has detected a medal under the first condition and the second condition. The check of the first condition is a check of the detection order of the two medal sensors. That is, first, only the medal sensor located near the medal slot detects, then the medal sensor located far from the medal slot also detects, and then only the medal sensor located near the medal slot detects. It is checked whether or not each medal sensor detects in a normal order that the medal sensors located far from the medal insertion slot end the detection at the end.

The check of the second condition is a check of whether or not the detection time of the two medal sensors is a predetermined time. That is, the time during which only the medal sensor at a position near the medal slot is detecting, the time at which the medal sensor at a position near the medal slot and the medal sensor at a position far from the medal slot are detected, and It is checked whether or not all of the times detected only by the medal sensor located far from the insertion slot are within a predetermined time.

When these two conditions are satisfied, the control unit confirms that a medal has been inserted. If the control unit cannot confirm the insertion of a medal, the control unit recognizes that there has been fraud regardless of whether or not the player has committed fraud, and the control unit may disable the medal game machine. it can.

EXAMPLES Hereinafter, the present invention, that describes in more detail have not a group in the Examples and drawings, which illustrate it. FIG. 1 is a conceptual diagram showing an embodiment of the present invention. FIG. 2 and FIG. 3 are conceptual diagrams showing how the medal sensor a21 and the medal sensor b22 provided in the present embodiment detect medals passing through the medal passage 10, and FIG. FIG. 3 shows a state in which the medals pass through the medal passage 10 in an appropriate state in which the medals can be pulled back, and FIG.

Although FIG. 4 shows a conventionally used means for detecting the insertion of medals, it will be described with reference to FIG. 4 as necessary. Hereinafter, the configuration of the present embodiment will be described. The inserted medal detection device includes a medal passage 10 for taking the medal 30 inserted from the medal slot of the medal game machine into the medal game machine, two medal sensors 20 for detecting the medal 30 passing through the medal passage 10, and A control unit (not shown) for setting the game machine to a game startable state in response to information indicating that the medal sensor 20 has detected the medal 30 is formed.

The medal passage is formed from a medal passage introduction member 11, a medal passage front member 12, and a medal sorting machine 13 communicating with the medal insertion port from the medal insertion port toward the medal stocker. Explaining with reference to FIG. 4, the medal selector 13 is a member for eliminating the insertion of medals other than medals used in the medal game machine. According to the medal selecting machine 13, among the inserted medals, inappropriate medals are discharged out of the medal game machine, and only proper medals are taken into the game machine.

The medal passage 10 in the medal selector 13 is
The medal passage middle part 14 is slightly inclined from the horizontal, and the medal passage rear part 15 is further inclined continuously from the medal passage middle part 14. Two medal sensors 20
Are formed by an optical sensor, and are provided adjacent to each other in the medal passage 10 of the medal selector 13, more specifically, near a boundary between the medal passage middle portion 14 and the medal passage rear portion 15. Here, the one located closer to the medal slot is the medal sensor a21, and the one farther from the medal slot is the medal sensor b22.

Each medal sensor 2 adjacent to each other
0 is fixed in the medal path 10 so that the distance between the detection units for detecting the medals is smaller than the diameter of the appropriate medals 30 used in the medal game machine. For this reason, as shown in FIG.
1 and the medal sensor b22 may be detected at the same time.

The control section checks information indicating that each medal sensor 20 has detected the medal 30 under two types of conditions, and if the conditions are satisfied, sets the medal game machine to a game startable state. The two types of conditions checked by the control unit will be described in more detail with reference to FIGS. 2 and 3.

The first condition is whether or not each medal sensor 20 detects in a normal order. That is, the normal order means that only the medal sensor a21 detects first, then the medal sensor a21 and the medal sensor b22 detect, then only the medal sensor a21 ends detection, and finally only the medal sensor b22. End the detection.

The second condition is whether or not each medal sensor 20 performs detection in a normal detection time.
That is, when the time during which only the medal sensor a21 is detecting is A, the time during which the medal sensor a21 and the medal sensor b22 are detecting is B, and the time when only the medal sensor b22 is detecting is C, A and B , C are checked within a predetermined time.

Here, the predetermined time is, for example, as follows. 1.8 7 7 3 ms <A <15 0.18 4 ms 1.8 7 7 3 ms <B <9 9 4 9 6 9 ms 1. 8 7 7 3 ms <C <150 0 .8 1 8 4 ms Note that “ms” = “milliseconds” = 1/1000 seconds.

As described above, the one for which the predetermined time has been set makes it easy to find fraud and the game progresses smoothly, but the predetermined time is not limited to this. For example, it is individually and specifically set according to various conditions of each medal game machine, such as the inclination of the medal passage 10. In the example shown in FIG. 3, although the second condition is satisfied, since the medal sensor a21 has detected twice and does not satisfy the first condition, it is not recognized that a medal has been inserted.

When the above two conditions are satisfied, the control unit recognizes that the medal 30 has been inserted into the medal game machine, and usually enters a game start time state. If so, credits may be counted. Next, the operation of the present embodiment will be described.

A case where a player inserts a proper medal into a medal game machine equipped with the inserted medal detecting device according to the present invention will be described. The player inserts the medal 30 from the medal insertion slot. Medals entered 30
Are introduced into the medal game machine by being guided to the medal passage 10.

The medal sensor a21 located near the medal insertion slot detects the passage of the medal 30 and informs the controller of that fact. Next, the medal sensor b22 located at a position far from the medal insertion slot detects passage of the medal 30 and transmits the detection result to the control unit. The control unit receives information indicating that the medal sensor 20 has detected a medal, performs a check on the two conditions described above, and transmits the information to the medal game machine only when the information received from the medal sensor 20 satisfies the two conditions. It recognizes that the medal 30 has been inserted, and generally issues a command to make the game startable.

If the medal game machine has a so-called credit function, the credit may be counted. After receiving an instruction from the control unit to make the game startable, the player can play with the medal game machine. On the other hand, if the control unit cannot confirm the insertion of the medal, regardless of whether the player has committed fraud,
The control unit recognizes that the fraud has occurred, and the control unit can disable the medal game machine.

Next, the effect of this embodiment will be described.
According to the present embodiment, at the time of medal insertion, the game cannot be started even if an illegal operation such as pulling back the inserted medal is performed, that is, each medal sensor 20 detects the medal in a normal order, and Since the inserted medal detecting device that can start the game only when the medal sensor 20 detects the normal detection time is provided, there is an effect that the illegal action can be effectively prevented.

In particular, the medal detection device introduced in this embodiment is
"The distance between the detection units for each of the medal sensors 20 adjacent to each other to detect medals in the medal passage 10 is determined by the appropriate medal 3 used in the medal game machine.
Are arranged so as to be smaller than the diameter of 0 ”. Therefore, the "moment at which the medal sensor a21 and the medal sensor b22 detect at the same time" can also be set as a target for checking the normal detection time, so that it is possible to deal with a subtle fraud.

Next, variations of this embodiment will be described. In this embodiment corresponding to the invention described in claim 1, the medal sensors 2 adjacent to each other
It is assumed that the length of “0” in contact with the medal passage 10 is smaller than the appropriate diameter of the medal 30 used in the medal game machine, and the medal game machine starts the game only when the control unit satisfies the two conditions. Although it has been described that the command is issued so that the state is enabled, the present invention is not limited to this. Contract
In the invention described in claim 1, a condition for the control unit to recognize that the medal game machine has inserted a medal is described, but other conditions may be imposed to perform a more strict check. It is.

In the present embodiment, the medal sorter,
The position where the plurality of medal sensors 20 are attached is not particularly mentioned, but the present invention is not limited to the above-mentioned embodiment. As the medal sorting machine, a conventionally used medal sorting machine may be used, or a medal sorting machine newly designed so as to be optimal for mounting the plurality of medal sensors 20 may be used. Further, the plurality of medal sensors 20 are not limited to being mounted on the medal selector, but may be mounted anywhere in the medal passage 10.

Further, in the present embodiment, an optical sensor is employed for each medal sensor 20 and the number is two, but the present invention is not limited to this. For example, a magnetic sensor is employed, and the number thereof is set to three or more, and information indicating that all the medal sensors have detected medals is transmitted from a position related to a position close to the medal insertion port in the medal passage to the medal insertion port. The control unit may be formed such that the medal game machine is set to the game startable state only when the medal game machines are sequentially received.

[0035]

According to the first aspect of the present invention, the game can be started even if a skillful injustice is performed at the time of medal insertion by checking under two conditions that the medal insertion has been normally performed. There is an effect that it is possible to provide an inserted medal detection device that cannot be performed.
