Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine for playing a pachinko game and the like, and more particularly, to a gaming machine with improved control board visibility and noise resistance.

[0002]

2. Description of the Related Art Generally, a plurality of gaming machines such as pachinko machines at a game arcade are provided side by side on one or both sides of a facility called a gaming island, and are operated by circulating gaming balls held in the gaming island. In this game island, a long circulation path is formed for circulation of the branch ball, and the game ball is charged by friction etc. by rolling the game ball on the path, or it is provided in the circulation path Similarly, the game balls are easily charged by being polished by a ball polishing device or the like. On the other hand, gaming machines are provided with a large number of electric drive sources such as motors and solenoids in the role of a game board, and the game can be performed by operating these electric drive sources. These electric driving sources also cause noise such as static electricity and electromagnetic waves.

A game machine of this type includes a plurality of control boards on which a control circuit for controlling the operation of the electric drive source and the like is formed. The control boards are provided in a board storage member as described later. Although it is provided as a housed control unit, particularly important control boards (such as the accessory control board) are not affected by the static electricity of the game ball and the noise generated from the electric drive source as described above. It is necessary to take measures. Conventionally, as a countermeasure, the substrate housing member that houses the control board is made of a conductive material (for example, metal), and the entire control board is covered with a conductor and shielded. Was. Alternatively, the substrate storage member is made of a synthetic resin or the like,
Conventionally, a metal plate, for example, is provided for each substrate on both sides of the control board in the board storage member, and the front and rear faces of the control board are covered and shielded. Since ordinary materials such as conductive metal cannot be seen through, the conductive substrate housing member or plate is usually provided with large openings and a large number of holes in an aligned state. Thus, the internal mounted components and the like can be partially viewed.

Recently, a fraudulent person has invaded a game store at night, and an RO on a control board for storing a game control program and the like has been disclosed.
Replacing M, etc., or attaching other unauthorized parts, illegally remodeling the gaming machine so that only some fraudsters can gain illegal profits, causing damage to the amusement store . For this reason, a seal such as fixing with a one-way screw is attached to the board storage member of the control unit, which is particularly important for the progress of the game (such as an accessory control unit), so as not to perform such misconduct. Measures have been taken to make it easy to determine whether the package has been opened. In addition, as a countermeasure for reducing the influence of the above-described noise, static electricity, and the like, there may be a case where control is devised. That is, for example, in order to cope with a runaway of the CPU or the like, the game control is executed by resetting every 2 ms, for example. However, such control noise measures alone are not enough, and it is necessary to physically shield the control board from the aforementioned static electricity and electromagnetic waves.
The above-mentioned countermeasures such as making the substrate housing member made of metal have been implemented. Some conventional gaming machines have a power supply circuit for each control unit, and a DC power supply of a predetermined voltage level (for example, 5 V) is produced for each control unit from a commercial power supply.

[0005]

However, the above-mentioned conventional gaming machine has the following problems in view of the visibility of the control board and the like. In other words, since the control board is covered with a considerable portion of a metal plate or the like, if the control unit (board storage member) is not opened, everything including the front and back of the control board (mounting parts, circuit patterns, etc.) Was not visible. For this reason, if an improper person replaces a mounted component on the control board with an improper component, or if an improper component is mounted in the board storage member, a store clerk of an amusement store or the like performs a check operation during maintenance and inspection. Even so, it was difficult to find it, and there was a risk that the damage would spread without noticing that it had been tampered with for a long time.

[0006] This is because it is not easy for some unauthorized persons to replace parts by force from the overlapping portion of the upper and lower lids of the substrate storage member while sealing, or to easily break the sealed portion. There are some things that are modified and illegally modified as described above, but if the seal is destroyed at the amusement store's discretion, the use as a gaming machine may not be permitted, so clerks at the amusement store etc. This is because the confirmation work at the time of maintenance inspection or the like is usually performed without opening the control unit. In other words, the control unit must perform the checking work without breaking the seal, and the checking work cannot be performed with the control board uncovered. In some cases, illegal activities could not be discovered for a long time. In addition, for the same reason, the work of checking the control board is very troublesome and time-consuming.

Further, since a metal plate or the like for protecting each control board from noise or static electricity is conventionally provided for each control board (each control unit), the number of parts related to the control unit is large. Thus, there has been a problem that the assembling work and the remodeling work of the gaming machine become troublesome, and the production cost and the maintenance cost of the gaming machine increase accordingly. In particular, when a DC power supply is created for each control unit, a power supply circuit is required for each control unit, and all control boards (each control unit) are correspondingly larger, which further increases costs. Had become.

Although it is conceivable to form a control unit without using a conductive member, simply removing the shield from the control unit weakens the function as a GND (ground, that is, a ground plane). Also, it becomes extremely weak to the aforementioned noise. Therefore, the present invention
At least the contents of the important control unit (for example, the accessory control board) can be seen well, and the game machine is resistant to noise and the like. Further, the configuration of each control unit and its related components (particularly, the control unit is protected from noise and the like) The purpose of the present invention is to provide a gaming machine whose configuration is simplified.

Further, in this case, the sound control unit 23 is attached to the conductive member 47 and further attached to the attachment base 46 as described below. That is, first, the sound control unit 23 is inserted into the U-shaped portion 47c of the conductive member 47 attached to the attachment base 46 while the rear surface side of the sound control unit 23 is slightly inclined downward. When the upper surface of the rear end of the sound control unit 23 is inserted to a position where it comes into contact with the lower surface side of the above-described protruding piece 47d formed in the U-shaped portion 47c, the sound control unit 23 is inserted into the U-shaped portion 47c. The insertion hole of the projection 68 of the case 67 is overlapped with the above-mentioned fastening hole formed in the projection 54 of the projection 46 b of the mounting base 46 so as to be parallel to the bottom surface of the case 67.

(See FIG. 3).

Thereafter, the fastening member 82 is inserted through the insertion hole of the projecting piece 68 of the case 67 and is pushed into the fastening hole of the projection 54 provided on the mounting base 67. As a result, the sound accessory control unit 17 and the conductive member 47 are simultaneously fixed to the mounting base 46 in a superposed state, and at the same time, the front end surface of the press contact portion 57 is positioned at a predetermined position on the back surface of the sound control board 66. At a predetermined pressure (that is, press-contact). In addition,
By the procedure reverse to the above, the sound control unit 23 and the conductive member 47 can be easily removed from the mounting base 46 (that is, the gaming machine 1). However, in this case, when the accessory control unit 17 is attached as described above, the conductive member 47 cannot be removed even if only the sound control unit 23 is removed. Further, at a predetermined position on the back surface of the sound control board 66 against which the front end face of the press-contact portion 57 is pressed, a ground electrode of the sound control board 66 or a circuit conductor on the sound control board 66 which is in conduction with the ground electrode is provided.

Are formed.

On the other hand, the case 75 of the discharge control unit 16
Projection pieces 81 are formed at three upper and lower positions and two positions on the upper right and left ends of the case 71 of the decoration control unit 27. The insertion holes of the fastening members 82 are formed in the projections 81. It is formed, and a fastening member 82 is attached in advance as necessary. Each control unit 1 is located at a position (four places) corresponding to the press-contact portion 80 on the bottom side of the case 75 and the case 71 (the front side of the gaming machine 1a).
When the conductive members 76 and the conductive members 76 are attached, a pressure contact portion 83 (control board side conductive portion) that comes into pressure contact with the pressure contact portion 80 by surface contact is provided. The press contact portion 83 is provided in the case 7
5 or a ring-shaped (nut-shaped) member provided to protrude from the bottom surface of the case 71 toward the conductive member 76;
For example, it is formed of metal or the like and has conductivity. And
In this case, the press contact portion 83 has a screw hole formed in the inner peripheral portion. For example, in the case of the press contact portion 83 provided in the case 75, the screw member 84 inserted through the discharge control board 74 and the wall of the case 75. Is screwed into a screw hole in the press-contact portion 83 (see FIG. 5), whereby the case 7
5 is fixed at a predetermined position. The screw member 84 is
It is also made of a conductive metal or the like.
5, the bottom surface of the head is pressed against the ground electrode (or a circuit conductor connected to the ground electrode) on the discharge control board 74, and the press contact portion is formed via the screw member 84. 83 is electrically connected to the ground electrode (ground terminal of the accessory control circuit) of the discharge control board 74. FIG. 5 shows a partial cross section of the state in which the discharge control unit 16 and the conductive member 76 are attached to the base frame 22. The upper part in the drawing is the upper side of the gaming machine 1 in this case, and The left side is the back side (rear side) of the gaming machine 1 in this case. The attachment state of the decoration control unit 27 (including the attachment structure of the press contact portion 83 provided in the case 71 and the conductive configuration with the decoration control board) is not shown, but the discharge control unit 16 shown in FIG. And the same configuration.

In this case, the discharge control unit 16 or the decoration control unit 27 and the conductive member 76 are simultaneously mounted on the base frame 22 (mounting base) in the following manner. That is, first, each fastening portion 7 of the base frame 22
7 is fitted into each of the fastening holes 79 of the conductive member 76, and the tip of each of the fastening portions 77 is projected toward the surface of the base frame 22. Thus, the conductive member 76 is positioned with respect to the base frame 22 that is the mounting base. Next, for example, the entire discharge control unit 16 is connected to the conductive member 7.
6 so as to overlap the front side of the plate-shaped portion 76a (the back side of the gaming machine 1a), and insert the insertion end portion 82b of the fastening member 82 inserted into each protruding piece 81 of the case 75 into the corresponding fastening portion 77. , And each fastening member 82 is pushed in. As a result, the discharge control unit 16 is attached to the base frame 22 in a substantially fixed state by the locking action of the fastening member 82, and at the same time, the press contact portion 83 of the case 75 presses the corresponding press contact portion 80 by surface contact. Thus, the conductive member 76 is electrically connected to the ground electrode of the discharge control board 74, and the conductive member 76 is attached to the base frame 22 in a substantially fixed state (see FIG. 5).

Also, the insertion end 82b of the fastening member 82 inserted into each of the projecting pieces 81 of the case 71 is arranged so that the entire decoration control unit 27 is superimposed on the surface of the plate-like portion 76b of the conductive member 76. Then, each of the fastening members 82 is inserted into the corresponding fastening hole of the fastening portion 77 and each fastening member 82 is pushed in. As a result, the decoration control unit 27 is locked by the fastening member 82 so that the base frame 22
At the same time, the press contact portion 83 of the above-mentioned case 71 is pressed against the corresponding press contact portion 80 by surface contact,
The conductive member 76 also conducts to the ground electrode of the decoration control board (not shown). At this time, the support portion 78 formed on the base frame 22 abuts on the back surface of the conductive member 76 to support the back surface of the conductive member 76, and the base frame 22 and the conductive member 76 A space is formed between them (see FIG. 5). In addition, the discharge control unit 16 or the decoration control unit 27 and the conductive member 76 are connected to the base frame 2 by a procedure reverse to the above.
2 (that is, the gaming machine 1).

E. Configuration of Power Supply System of Control Unit Next, the configuration of the power supply system of each control unit will be described. In this case, the power supply of each control unit in the gaming machine of this example is supplied from a common power supply unit 90 provided in a discharge control circuit formed on the control board 74 of the discharge control unit 16 as shown in FIG. Have been. That is, the common power supply unit 90 is a stabilized power supply circuit that converts the commercial power supply supplied to the gaming machine 1 into a DC power supply having a constant voltage level required by each control unit. It is supplied to various circuits (emission control circuit, decoration control circuit, display control circuit, accessory control circuit, sound control circuit) formed on the control board of the control unit. That is, the basic power supply voltages of the respective control units are at the same level.

In the gaming machine described above, the cases 45 and 75 of the accessory control unit 17 and the discharge control unit 16 for which the inside needs to be visually checked are constituted by clear members, and the accessory control unit 17 and the mounting base are provided. 46
Or between the discharge control unit 16 and the base frame 22 (attachment base), conductive members 47 and 76 are provided, and these conductive members 47 and 76 are respectively connected to the accessory control board 44 or the discharge member. It is electrically connected to the ground electrode of the control board 74. Moreover, each of the conductive members 47 and 76 is also electrically connected to the ground electrode of the control board of another control unit (the sound control unit 23 or the decoration control unit 27). Unit and its mounting base (mounting base 46 or base frame 2
It is also arranged between 2). The conductive member 47 provided for the accessory control unit 17 and the sound control unit 23 is formed so as to protrude into the accessory control unit 17 or the sound control unit 23, and When the unit 17 or the sound control unit 23 and the conductive member 47 are assembled, the press-contact portions 58 and 5 whose front ends press-contact a predetermined ground electrode or circuit conductor on each control board.
7 are provided, and the press contact portions 58, 67 are provided in the cases 45, 67 of the accessory control unit 17 or the sound control unit 23.
Openings 59 and 69 through which 57 penetrate are provided. Further, the mounting base 46 includes a common mounting portion (fastening portion 52) to which the conductive member 47 and the accessory control unit 17 can be mounted simultaneously.

The conductive members 76 provided for the discharge control unit 16 and the decoration control unit 27 include:
A press-contact portion 80 (conductive member-side conductive portion) protruding toward the discharge control unit 16 or the decoration control unit 27 is provided. The discharge control unit 16 and the decoration control unit 27 are electrically connected to the ground electrode of each internal control board. When the discharge control unit 16 or the decorative control unit 27 and the conductive member 76 are assembled, the pressing portion 83 (control board side conductive portion) protruding toward the conductive member 76 is provided. The press contact portion 80 and the press contact portion 83 are pressed against each other so that the conductive member 76 and the ground electrode are brought into conduction. Further, the base frame 22 has a common attachment portion (fastening portion 77) that can simultaneously attach the conductive member 76 and the discharge control unit 16 or the decoration control unit 27.
It has. Therefore, the following various effects can be obtained.

(1) With the accessory control unit 17 and the discharge control unit 16 removed (that is, the unit alone), the caulking members 64 and the like that seal the cases 47 and 75 of these control units are cut off. Without this, all of the accessory control board 44 and the discharge control board 74 are in full view, and the electronic components (CPU
Etc.) can be clearly seen and fraudulent acts such as replacement of parts by fraudulent persons can be easily detected, fraudulent acts are deterred, and when fraudulent acts are performed, immediate detection is performed to minimize damage to the game store It becomes possible to do. (2) Even when the accessory control unit 17 and the ejection control unit 16 are mounted on the gaming machine 1, the surfaces of the accessory control board 44 and the ejection control board 74 are completely visible from the back side of the gaming machine, and are controlled by a staff member during maintenance and inspection. It is easy to check the unit 17 and the discharge control unit 16.

(3) After the insides of the control unit 17 and the discharge control unit 16 are easy to see, the conductive members 47 and 76 which are superposed on the control unit 17 and the discharge control unit 16 and grounded are installed. The CPU of the accessory control board 44 and the discharge control board 74
Runaway (or malfunction) can be prevented with high reliability. That is, the incidence of noise such as electromagnetic waves from the outside of the unit and the influence of the magnetic field are effectively blocked by the conductive members 47 and 76, and the static electricity and the like of the accessory control board 44 and the discharge control board 74 are eliminated. The discharge of the conductive members 47 and 76 prevents malfunctions and runaway of the circuits of the accessory control board 44 and the ejection control board 74 (that is, the accessory control circuit and the ejection control circuit). In addition, in the case of the present example, the pressing members 5 are attached to the conductive members 47 and 76.
8 and the press-contact portion 80, and the conductive members 47 and 76 are connected to another control unit (the sound control unit 23).
The surface area of the conductive members 47 and 76 is very large by the extent that the conductive members 47 and 76 also extend to the rear side of the decoration control unit 27), and the effect of the discharge is greatly improved. In addition, electromagnetic waves generated by various electric driving sources such as motors and solenoids on a game board, noise due to static electricity of a sphere, and the like (or illegal radio waves transmitted by an illegal player).
Usually enters the control unit such as the accessory control unit 17 from the front side of the gaming machine.
Even in a configuration in which 7, 76 is arranged only on the back side of the control unit (the front side of the gaming machine), it is possible to effectively block the incidence of these noises.

(4) The conductive member 47 is shared by the accessory control unit 17 and the sound control unit 23,
Since the conductive member 76 is common to the discharge control unit 16 and the decoration control unit 27, the number of parts is reduced accordingly. Further, since the common power supply unit 90 that supplies a common DC power supply to each control unit is provided, the configuration is simplified as compared with a case where a power supply circuit is provided for each control unit. For this reason, while being able to reduce parts cost and assembly cost of a gaming machine, or maintenance cost,
This is advantageous for reducing the weight and size of the gaming machine. Since a common power supply is used for each control unit, one of the control units has a structure in which the ground electrode of each control board of the plurality of control units is electrically connected via a common conductive member. There is also an effect of preventing unnecessary current from flowing from the substrate to the other control substrate. That is, when a separate power supply is used in each control unit, a potential difference may occur in the power supply voltage. In this case, the ground electrodes of the plurality of control boards are connected via a common conductive member. In such a case, unnecessary current may flow between the ground electrodes of the control boards, and a problem such as an increase in power consumption (loss) may occur. There is also an advantage to be done.

(5) Further, since the conductive members 47 and 76 are arranged only on the rear side of the accessory control unit 17 and the discharge control unit 16, only these control units are separated from the conductive members 47 and 76. The work of removing from the gaming machine can be easily performed. In particular, in this example, for example, the conductive member 4
7 (plate-like portion 47b) is located between the accessory control unit 17 and its mounting base 46, and another portion (U-shaped portion 47c) of the conductive member 47 is the sound control unit 23 and its Since the conductive member 47 is mounted between the mounting base 46 and the mounting base 46 together with the accessory control unit 17 or the sound control unit 23, the conductive member 47 is mounted together with the sound control unit 23. Only the accessory control unit 17 can be easily removed from the mounting base 46 and the conductive member 47 while being attached to the base 46. For example, the work of detaching only the accessory control unit 17 alone can be performed. There is an advantage that makes it easier. Similarly, it is also easy to detach and attach only the discharge control unit 16 from the conductive member 76, for example.

(6) For example, when the accessory control unit 17 and the conductive member 47 are assembled, the conductive member 47
Is pressed against the accessory control board 44, the connection between the conductive member 47 and the earth electrode of the accessory control board 44 is automatically performed (without being noticed by the operator). . Also, for example, when the discharge control unit 16 and the conductive member 76 are assembled, the conductive member 76
The pressure contact portion 80 provided on the discharge control unit 16 presses the pressure contact portion 80 provided on the
6 and the ground electrode of the discharge control board 74 are automatically (without being conscious of the operator). For this reason, assembling work becomes easier, the number of parts is reduced, and the number of parts is reduced, as compared with a configuration in which separate connecting parts (for example, a cable and a connector) are attached and the connecting work is performed separately. Cost can be realized.

(7) In the present embodiment, since the above-mentioned press contact is performed by surface contact, conduction between the ground electrode of each control board and the conductive member can be achieved with high reliability with particularly low contact resistance. is there. This effect is particularly practical when the control unit is frequently attached and detached, for example, when the accessory control unit is attached to the base frame 22 of the back mechanism panel 24. In other words, in this case, if the electrical contact for conduction between the ground electrode of the control board of the accessory control unit and the above-mentioned conductive member is low in reliability, this should be carefully performed every time so that conduction failure does not occur. The work of attaching and detaching the control unit must be performed. However, in the case of the present embodiment, even if the worker is not particularly conscious due to the surface contact of the conducting portion or the press contact portion as described above, the conducting is performed with a particularly high reliability. There is an effect that the remodeling work of the gaming machine involving replacement is particularly easy.

(8) For example, without mounting the conductive member 47 on either side of the accessory control unit 17 or the sound control unit 23 and the mounting base 46, and simultaneously mounting the accessory control unit 17 or the sound control unit 23, Since the conductive member 47 can also be attached, when the accessory control unit 17 and the sound control unit 23 are detached from the attachment base 46, the conductive member 47 can be detached at the same time.
The inside of the attachment base 46 and the inside of the accessory control unit 17 can be immediately visually checked, so that the checking operation is easy and the operation time can be reduced. Similarly, the conductive member 76 is connected to the discharge control unit 1.
6, decoration control unit 27 and base frame 22 (mounting base)
Without attaching the discharge control unit 16 or the decoration control unit 27 to the conductive member 76 at the same time.
Can be attached, so that the discharge control unit 1
6 and decoration control unit 27 to base frame 22 (mounting base)
In this state, the conductive member 76 can be removed at the same time, and the inside of the mounting base 76 and the inside of the discharge control unit 16 can be immediately visually checked, so that the checking operation is easy and the working time can be reduced.

It should be noted that the present invention is not limited to the above-described embodiment, but may have various modifications and applications. For example, the conductive member may be configured so as to be integrally mounted on any of the control units in advance, or may be configured to be integrally mounted on the mounting base side in advance. Further, in the above example, the fastening member 82 as described above is used as the attachment, but it goes without saying that a normal screw member can be used instead. Also, for example, the accessory control unit and the like are not limited to the mode of being attached to the back of the game board unit,
When there is no space for mounting the accessory control unit or the like on the back surface of the game board unit, for example, it may be mounted on the base frame of the back mechanism board. In this case, since the accessory control unit is exchanged together with the exchange of the game board unit, the attachment and detachment of the accessory control unit from the mounting base or the like is frequently performed, but in the case of the configuration of the present invention, Since this is easy to attach and detach, the remodeling operation of the gaming machine involving replacement of the gaming board unit is facilitated.

In the above embodiment, the conductive members 47,
Although 76 is not electrically connected to the metal frame 3 that houses the game board 41, it may be connected by a lead wire or the like so as to be electrically connected. In this case, there is an effect that the area of the ground electrode on the substrate such as the accessory control board 44 or the discharge control board 74 is further increased, and the static electricity or the like of each control board can be discharged from the metal frame 3. .

The present invention is applicable not only to pachinko machines but also to arrange ball machines and slot machines. Further, instead of the caulking member 64 described above, an opening identification seal (a seal that can be recognized when the case is opened) may be used. In addition, the conductive portion (conductive portion on the conductive member side, conductive portion on the control board side) and the pressure contact portion of the present invention do not necessarily have to be provided in a protruding state as literally, and a predetermined contact state can be obtained. With a configuration, for example, it may simply face the control unit side or the conductive member side.

[0055]

According to the gaming machine of the first aspect, of a plurality of control units for controlling any one of the electric appliances, a specific control unit (for example, As for the accessory control unit), the control board accommodating member for accommodating the control board (for example, the accessory control board) can be seen through, and the control unit and an attachment base for attaching the control unit to the back side of the gaming machine are provided. A conductive member is disposed between the control substrate and the conductive member, and the conductive member is electrically connected to a ground electrode of the control board, and is also electrically connected to a control board of another control unit (for example, a sound control unit). . For this reason, in a state where the specific control unit is removed (that is, a unit alone), all of the control boards in the control unit are cut without cutting off the swaging that seals the control board storage member of the control unit. Becomes visible and the electronic components (CP
U) etc. can be clearly seen and fraudulent acts such as replacement of parts by fraudulent persons can be easily detected, fraudulent acts are suppressed, and if fraudulent acts are performed immediately, damage to the game store is minimized It becomes possible to.

Further, even when the control unit is mounted on the game machine, the front surface of the control board of the specific control unit is exposed from the back side of the game machine, so that the staff can easily check the specific control unit during maintenance and inspection. . Also,
At least the inside of the specific control unit is easy to see, and a conductive member that is connected to the specific control unit and grounded by being superimposed on the specific control unit is installed. Runaway (or malfunction) can be prevented with high reliability. That is, the incidence of noise such as electromagnetic waves from the outside of the unit and the influence of a magnetic field will be effectively cut off by the conductive member, and the static electricity and the like of the control board will be discharged from the conductive member. A malfunction or runaway of a circuit on a control board of a specific control unit is prevented. In addition, the control board of another control unit in which the ground electrode is connected to the conductive member is also protected from static electricity and the like by the conductive member, so that malfunction and runaway of the circuit are less likely to occur.

In particular, as described in claim 2, a part of the conductive member is located between the specific control unit and the mounting base, and another part of the conductive member is connected to another control unit and the mounting base. In the case of a structure located between, while being a single conductive member, the effect of the incidence of noise and magnetic fields such as electromagnetic waves directed to other control units will be effectively cut off, The surface area of the conductive member is increased, the action of the discharge is further enhanced, and more effective protection of a plurality of control units can be achieved with one conductive member. Further, as described in claims 3 to 6, when the conductive member is provided with the conductive portion and the press contact portion, the surface area of the conductive member is reduced by the provision of the conductive portion and the press contact portion. Further, the effect of the discharge is further improved.

According to the gaming machine of the first aspect, a member for protecting each control unit from noise or the like (ie, a conductive member) is shared by any one of the plurality of control units. Therefore, the number of parts is reduced accordingly. Further, since a power supply unit for supplying a common DC power supply to each control unit is provided, the configuration is simplified as compared with a case where a power supply circuit is provided for each control unit. For this reason, it is possible to reduce the parts cost and the assembly cost or the maintenance cost of the gaming machine, and it is advantageous in reducing the weight and size of the gaming machine. In addition, since a common power supply is used in each control unit, the ground electrode of any one of the plurality of control boards is electrically connected through a common conductive member. There is also an effect of preventing unnecessary current from flowing to the other control board.

According to the first aspect of the present invention, since the conductive member is disposed only on the rear side of the control unit, it is easy to separate the control unit from the conductive member and remove the control unit from the game machine. It becomes possible. In particular, claim 2
As described in the above, a part of the conductive member is located between the specific control unit and the mounting base, and another part of the conductive member is located between the other control unit and the mounting base. In this case, for example, it is easy to remove only a specific control unit from the mounting base and the conductive member, and to leave the conductive member as it is between the other control unit and the mounting base. There is an advantage that the work of detaching and attaching only the control unit alone becomes easy.

According to the gaming machine of the present invention, the conductive member and the contact portion provided on the side of the conductive member or the control board make the conductive member and the ground electrode of the control board conductive. This is the configuration. For this reason, assembling work becomes easier and the number of parts is reduced, as compared with a configuration in which separate parts for connection (for example, a cable and a connector) are attached and the connection is performed separately, for example.
Low cost can be realized. In particular, according to the gaming machine according to claim 5 or 6, when the accessory control unit and the conductive member are assembled, by pressing the conductive member side conductive portion and the control board side conductive portion, Alternatively, when the pressure contact portion provided on the conductive member presses against the control board, the connection between the conductive member and the ground electrode of the control board is automatically performed (without being noticed by an operator). For this reason, assembling workability is improved, and assembling cost can be further reduced.

According to the seventh aspect of the present invention, since the pressure contact is performed by surface contact, conduction between the ground electrode of the control board and the conductive member can be realized with high reliability with a particularly small contact resistance. There is a working effect. This operation and effect can be achieved, for example, by the control unit according to the ninth aspect.
This is of particular practical significance if the control unit is frequently detached. In other words, in this case, if the electrical contact for conduction between the ground electrode of the control board of the control unit and the above-mentioned conductive member is unreliable, this control unit is carefully carefully controlled every time so as to prevent poor conduction. Has to be desorbed. However, in the case of the present invention, even if the worker is not particularly conscious due to the surface contact of the conducting portion or the press contact portion as described above, the conducting is performed with a particularly high reliability. There is an effect that the remodeling work of the gaming machine involving replacement is particularly easy.

According to the gaming machine of the present invention, any one of the control units and the conductive member which is electrically connected to the ground electrode of the control board of the control unit can be simultaneously mounted. The part is provided in the mounting base. That is, it is possible to mount the control unit and also mount the conductive member without mounting the conductive member on either side of the control unit or the mounting base. Therefore, when the control unit is removed from the mounting base, the conductive member can be removed at the same time. Therefore, the detachability of the control unit is improved, and both the inside of the mounting base and the inside of the control unit can be checked immediately. The confirmation work becomes easier, and the work time can be further reduced.

According to the game machine of the ninth aspect, the game board unit is configured to be detachable from the game machine, and the specific control unit is exchanged together with the game board unit. A control unit (for example, an accessory control unit) that needs to be mounted is attached to a member (for example, a base frame of a back mechanism board) other than the game board unit among members constituting the back surface of the gaming machine. For this reason, the present invention is applied to a control unit that needs to be frequently attached to and detached from the mounting base, and there is an effect that a remodeling operation of a gaming machine involving replacement of a gaming board is facilitated. In other words, for example, the function of the accessory control unit (the function of the game control) is closely related to the configuration of the game board (the configuration of the game area). Is also exchanged with a unit corresponding to the new game board unit. At this time, if such a control unit is mounted on the back side of the game board unit, it can be easily replaced together with the game board unit. Because there is no
When such a control unit is attached to a part other than the game board unit, it is necessary to remove and attach this control unit independently from the part other than the game board unit, and to attach and detach a new control unit to that part every time become. In this case, if the detachability of the control unit with respect to the conductive member is poor, the operation is troublesome.

However, in the case of the present invention, the conductive member is provided on the rear side of the control unit (between the mounting base) and, in some cases, a part thereof is also provided on the rear side of another control unit. Since the control unit has good detachability with respect to the conductive member, the above-mentioned operation is relatively easy. In addition, in the case where the above-described conduction is performed by the surface contact of the conduction portion or the press-contact portion as described above, the above-described conduction is performed with a particularly high reliability without the worker being particularly conscious. There is an extremely practically excellent effect that the remodeling work of the gaming machine accompanying such a game board exchange becomes easier.
