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 one or more control boards on which a control circuit for controlling the operation of the electric drive source and the like is formed. Although it is provided as a control unit sealed and housed in the member, so that the control board in this control unit is not affected by the static electricity of the game ball and the noise generated from the electric drive source, 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,
For example, a metal plate is disposed 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 . Therefore, in order to prevent such misconduct from taking place, measures are taken such that the board storage member of the control unit is sealed, such as fixed with a one-way screw, so that it can be easily identified whether or not the board storage member has been opened. ing.
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 above-mentioned static electricity and electromagnetic waves. Measures were being taken.

[0005]

However, the above-mentioned conventional gaming machine has the following problems in view of the visibility of the control board. That is, since the control board is covered with a considerable part by a metal plate or the like, if the control unit (board storage member) is not opened, all of the control board including the front and back surfaces (circuit patterns and mounted electronic components) is required. Parts) could not be seen. 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. Some of them are modified to make unauthorized modifications. However, if the seal is destroyed at the game store's discretion, the use as a game machine may not be permitted. This is because it is performed without opening. 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.

Although it is conceivable to form the control unit without using a conductive member, simply removing the shield from the control unit weakens the function as GND (ground, that is, the ground plane). Also, it becomes extremely weak to the aforementioned noise. Therefore, the present invention
It is an object of the present invention to provide a gaming machine in which the contents of a control unit (that is, a control board) can be easily seen and which is resistant to noise and the like.

[0008]

In order to achieve the above object, a gaming machine according to the first aspect of the present invention includes a control unit for controlling any one of the electric components constituting the gaming machine,
In a gaming machine including an attachment base for detachably attaching the control unit to the back side of the gaming machine, the control unit includes a control board on which a control circuit for performing the control is formed; and A transparent control board storage member that stores the control board in a state of covering the periphery thereof, and the control board is configured to be visible from at least up and down, left and right, and front and rear, and the control unit is provided with respect to the mounting base. The control unit and the mounting base are provided with a conductive member between the control unit and the mounting base, and the conductive member is electrically connected to a ground electrode of the control board. And is detachably attached to the attachment base.

In a preferred embodiment, the conductive member may be a plate-like member having substantially the same shape and dimensions as one surface of the control unit on the mounting base side. Further, for example, as described in claim 3, the conductive member may be provided with an extending portion extending above the control unit.

The conductive member is formed so as to protrude into the control unit, and when the control unit is mounted on the mounting base, the conductive member has a tip. Is provided with a pressure contact portion that presses against the ground electrode or a circuit conductor on the control board that is in a conductive state with the ground electrode, and the control board housing member is provided with an opening through which the press contact portion penetrates. Is also good.

Further, for example, as set forth in claim 5, at least the game board is configured to be detachable from the game machine, and the control unit is also replaced together with replacement of the game board. The press-contact between the press-contact portion and the ground electrode or the circuit conductor is performed by surface contact.

The above-mentioned winning ball collecting member 33 is provided on the back side of the game board 41, and the rear of the center role object 42 is formed so as to protrude from the rear surface of the winning ball collecting member 33. Further, the accessory control unit 17 is arranged on the rear side of the winning ball collecting member 33 and on the right side of the center accessory 42 when viewed from the front of the gaming machine 1. Further, the accessory relay board 18 is mounted on the rear side of the center accessory 42.

The accessory control unit 17 electrically controls electrical components (electrical accessories) such as various switches, solenoids, and lamps provided on the game board 41. A control board 44 (shown in FIG. 3) on which a control circuit for performing (control) is formed is housed in a case 45 (control board housing member). Case 45
Is made of a clear material such as a transparent synthetic resin and is provided so as to cover the entire periphery of the control board 44. However, the entire control board 44 may be arranged in any direction outside the case 45 (at least, up, down, left, right, And before and after). As will be described later, the accessory control unit 17 is detachably attached to the back side of the game board 41 via an attachment base 46, and a conductive material is provided between the accessory control unit 17 and the attachment base 46. A conductive member 47 is provided, and the conductive member 47 is electrically connected to a ground electrode (not shown) of the control board 44 as described later.

The mounting base 46 is also made of a transparent member such as a transparent or translucent synthetic resin. If the accessory control unit 17 and the conductive member 47 are removed, the balls flowing in the winning ball collecting member 33 can be played. The structure is such that the back side of the machine 1 can be clearly seen through. And this mounting base 4
6 is positioned by engaging projections (not shown) provided on the back side (the front side of the gaming machine 1) with positioning holes 48 and 49 formed in the veneer member 43 of the game board 41, By nailing the veneer member 43 with nails inserted through a plurality of through-holes 50 provided on the periphery thereof, the veneer member 43 is fixed at a predetermined position on the game board 41. The conductive member 47 is a plate-like member made of a conductive material such as a metal or a conductive resin and having substantially the same shape and dimensions as the back surface (one surface on the mounting base side) of the accessory control unit 17. Here, the conductive resin is a material whose conductivity is increased by adding, for example, carbon to the resin.

In this case, the accessory control unit 17
The mounting base 46 also has a substantially rectangular parallelepiped shape as a whole, and the conductive member 47 accordingly has a rectangular shape as a whole. Further, the conductive member 47 is provided with a plurality of small holes 47a, which not only reduces the weight but also allows the conductive member 47 to be mounted on the mounting base 46 even when the conductive member 47 is mounted on the mounting base 46. However, it can be visually recognized in an approximate state. Therefore, even if a ball is clogged inside the winning ball collecting member 33, it can be quickly confirmed. Of course, it is needless to say that an embodiment in which such holes are not provided may be used. Further, the accessory control unit 17 is connected to the discharge / emission control unit 16 and the like by a cable, and is also connected to the accessory relay base 18 via a flat cable (see FIG. 1). In addition, the accessory relay board 18 is for relaying a cable connection between various accessories arranged on the game board 41 and the accessory control unit 17, and a relay board is provided inside the relay board box 18d. 18a, the connector board 18b, and the relay board 18
c is provided. Incidentally, the gaming board 41 can be replaced with a new one while leaving the front frame (that is, the main body of the gaming machine).
If the game board 41 is shipped from the manufacturer in a state of being integrated with the game board 41 through 6, it is possible to configure so that the accessory control unit 17 does not need to be attached or detached when the game board 41 is replaced at the game shop.

C. Next, details of the mounting structure of the accessory control unit 17 will be described with reference to FIGS. 2 and 3. As shown in FIG. 2, a fastening portion 52 is provided on the upper surface of the mounting base 46 (the back surface of the gaming machine 1).
A fastening hole corresponding to a fastening member 64 to be described later is formed in the end face. Further, protrusions 53 having screw holes are formed at four positions on the front side of the mounting base 46.
(Shown in FIG. 3) is provided, and a projecting piece receiving portion 54 is formed at a lower portion on the surface side of the mounting base 46. On the other hand, as shown in FIG.
Are provided at four positions corresponding to the through holes 5 through which screw members (not shown) to be screwed into the screw holes of the protrusions 53 are inserted.
5 are formed, and at the upper end and the lower end of the conductive member 47, an L-shaped press contact portion 56 formed so as to project toward the accessory control unit 17 is formed. When the accessory control unit 17 is attached to the attachment base 46 and the conductive member 47 as an integral product, the press contact portion 56
4 is pressed against the earth electrode or the circuit conductor conducted to the earth electrode by surface contact.

As shown in FIG. 3, the accessory control unit 17 is a flat control board 4 on which necessary electronic components 61 and the like are disposed.
4 is housed in the case 45 (control board housing member) described above. This case 45 includes a lid member 45.
a and the bottom member 45b, and by being formed of the clear member as described above, the entire control board 44 can be clearly seen from various external directions. For example, the control board 44 is passed through a transparent resin bottom member 45b.
Of the control board 44 and the electronic components 61 mounted on this surface can be visually recognized through the cover member 45a. This makes it easier for the third-party organization or the amusement shop employee to inspect the circuit for controlling the accessory on a regular basis.

Protrusions 62 for supporting and fixing the control board 44 are provided at four corner positions in the bottom member 45b of the case 45, and are inserted through through holes at the four corner positions of the control board 44, and screws on the end faces of the protrusions 62 are provided. The control board 44 is fastened to the projection 62 and fixedly supported by a screw member (not shown) screwed into the hole. Also, as shown in FIG.
A projecting piece 63 is formed on the upper end of the bottom member 45 b of the case 45, and a fastening member 64 corresponding to the fastening hole of the fastening part 52 is attached to the projecting piece 63. Fastening member 6
4 is an insertion end (not shown) on the tip side of a shaft extending from the head.
Is a well-known attachment which can be fastened by one-touch simple manual work. That is, when the fastening member 64 inserts and pushes the insertion end portion 64 into the fastening hole while pressing the head, the insertion end portion is enlarged in diameter and locked in the fastening hole, The insertion end is reduced in diameter by pulling the head, and the insertion end can be easily separated from the fastening hole.

The position of the bottom member 45b of the case 45 corresponding to the above-mentioned press contact portion 56 is
An opening 65 is provided to allow the inside to be inserted.
Further, the lower end of the bottom member 45b is provided with
A protruding piece 66 that can be fitted into is formed. In addition, a plurality (here, four) are provided on the upper and lower parts of the case 45.
A caulking member 67 is provided, and these caulking members 67 fix the lid member 45a and the bottom member 45b of the case 45 to each other and seal the case 45 so that the case 45 cannot be opened. . For example, when the case 45 is forcibly opened (for example, the internal control board 44
In such a case, the caulking member 67 must be cut with a cutting tool.
It can be determined whether the case 45 has been opened.

The accessory control unit 17 and the conductive member 47 are attached to the attachment base 46 as follows in this case. That is, first, the conductive member 47
Are attached to the mounting base 46 so as to overlap with each other, and a screw member (not shown) inserted into the through hole 55 of the conductive member 47 is
The screw is screwed into the screw hole of the projection 53 formed on the mounting base 46. Thereby, the conductive member 47 is integrally attached to the attachment base 46 as shown in FIG. Then
The above-mentioned protruding piece 66 formed on the case 45 of the accessory control unit 17 is fitted and locked in the protruding piece receiving portion 54 of the mounting base 46, and the back side of the accessory control unit 17 is
It is joined so as to overlap the front side of the mounting base 46 (the back side of the gaming machine 1). At this time, the above-mentioned press contact portion 56 formed on the conductive member 47 penetrates the above-mentioned opening 65 formed on the case 45 so that the front end surface thereof is opposed to or joined to the back surface of the control board 44. .

Then, the aforementioned fastening member 64 provided in the case 45 is pushed in, and the inserted end thereof is attached to the mounting base 46.
Into the fastening hole of the fastening portion 52 of FIG. Thereby, the accessory control unit 17 is substantially fixedly attached to the integral body composed of the attachment base 46 and the conductive member 47 by the locking action of the fastening member 64, and at the same time, the distal end surface of the press contact portion 56. Contact a predetermined position on the back surface of the control board 44 with a predetermined pressure (that is, press contact). In addition, the accessory control unit 17 and the conductive member 47 can be easily removed from the attachment base 46 (that is, the gaming machine 1) in a procedure reverse to the above. Further, at a predetermined position on the back surface of the control board 44 against which the front end face of the press-contact portion 56 is pressed, the ground electrode of the control board 44 or the control
The upper circuit conductor is formed in an exposed state, and in the above-mentioned assembled state, the ground electrode or the circuit conductor is reliably connected to the press contact portion 56 (that is, the conductive member 47).

In the gaming machine described above, the case 45 for accommodating the control board 44 of the accessory control unit 17 is formed of a clear member, and the conductive member 47 is provided between the accessory control unit 17 and the mounting base 46. The conductive member 47 is electrically connected to a ground electrode of the control board 44 of the accessory control unit 17. Further, the conductive member 47 is formed so as to protrude into the accessory control unit 17, and when the accessory control unit 17 and the mounting base 46 (conductive member 47) are assembled, the tip is controlled. A press contact portion 56 that presses against a predetermined ground electrode or circuit conductor on the substrate 44 is provided.
The case 45 has an opening 6 through which the pressure contact portion 56 penetrates.
5 are provided. Further, the mounting base 46 is
The conductive member 47 can be detachably attached by screwing the screw member into the third member 3. The conductive member 47 is a plate-like member having substantially the same shape and the same size as one surface of the accessory control unit 17 on the side of the mounting base 46. In the present embodiment, the conductive member 47 is not electrically connected to the metal frame 3 that houses the game board 41. However, the electrically conductive member 47 may be connected to the metal frame 3 with 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 control board 44 is further increased, and the static electricity and the like of the control board 44 can be discharged from the metal frame 3. As described above, the mounting base 46 may be integrated with the game board 41. However, when there is no place for disposing the mounting base 46 on the game board 41, the mounting base 46 is attached to the front frame side (ie, It may be provided at a predetermined position on the main body of the gaming machine). For example, a configuration may be adopted in which the mounting base 46 is mounted on the back mechanism board 24, and the conductive member 46 is mounted on the mounting base 46. In this case, when the game board 41 is replaced with a new one, the accessory control unit 17 also needs to be replaced with a corresponding one, so that the attachment and detachment frequency of the accessory control unit 17 inevitably increases. The pressure contact portion 56 formed on the conductive member 46 and the ground electrode on the control board 44 inside the accessory control unit 17 are configured to come into contact with each other by surface contact. Since there is no need to perform work, work efficiency is improved. Therefore, the following various effects can be obtained.

(1) With the accessory control unit 17 removed (that is, the unit alone), the caulking member 67 that seals the case 45 of the control unit 17 is not cut (that is, the case 45 is removed). Without opening), all of the control board 44 becomes fully visible, all the electronic components (CPU, etc.) mounted on the board 44 can be clearly seen, and it becomes easy to detect fraud by replacing a part by a fraudulent person, etc. In addition to deterring the act, it is possible to immediately detect an illegal act and to minimize damage to the game store. Particularly, in the case of this example, since the conductive member 47 is attached to the attachment base 46, if the control unit 17 is removed from the gaming machine 1 (the attachment base 46), the control board 44 will be exposed from the front side and the back side. Since only the control unit 17 is provided, a clerk at a game store or the like can easily confirm the unauthorized modification of the control board. (2) Even when the accessory control unit 17 is mounted on the gaming machine 1, the front surface of the control board 44 is exposed from the back side of the gaming machine so that the staff can easily check the control unit 17 during maintenance and inspection.

(3) After the inside of the control unit 17 is in an easy-to-view state, a conductive member 47 that is superimposed on the control unit 17 and is connected to the ground 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 the magnetic field are effectively blocked by the conductive member 47, and the static electricity of the control board 44 is discharged from the conductive member 47. Control board 4
Malfunction and runaway of the circuit No. 4 are prevented. Moreover, in the case of this example, the surface area of the conductive member 47 is increased by the amount of the press-contact portion 56 provided on the conductive member 47,
The effect of the discharge is further improved. In addition, the electromagnetic waves generated by various electric drive sources such as motors and solenoids on the game board, and noise (or
Normally, an illegal radio wave transmitted by an unauthorized player) enters the control unit such as the accessory control unit 17 from the front side of the gaming machine, so that the conductive member 47 is placed on the back side of the control unit (the gaming machine). However, even with a configuration arranged only on the front side), the incidence of these noises can be effectively blocked.

(4) When the accessory control unit 17 is assembled, the pressure contact portion 56 provided on the conductive member 47 is pressed against the control board 44 so that the conductive member 47 and the ground electrode of the control board 44 are grounded. Connection is automatically made (without the worker's awareness). For this reason, for example, compared with a configuration in which separate parts for connection (for example, a cable and a connector) are attached to perform the connection work separately,
Assembling work becomes easy, the number of parts is reduced, and low cost can be realized. (5) Since the conductive member 47 is mounted on the mounting base 46, the integrated product including the mounting base 46 and the conductive member 47 becomes an independent unit having a function of preventing noise and the like. Even if is changed, only the accessory control unit 17 needs to be replaced, and the unit consisting of the mounting base 46 (the above-mentioned integrated product) can be used in common as it is, even if the model is changed. , Resulting in cost savings. (6) When the control unit 17 is removed for inspection or replacement, if the conductive member 47 is left attached to the mounting base 46, it is convenient because the conductive member 47 will not be lost.

(7) Since the conductive member 47 is a plate-like member having substantially the same shape and the same size as one surface of the accessory control unit 17 on the side of the mounting base 46, a conductive member is provided between the control unit 17 and the mounting base 46. Although the configuration is such that the sexual member 47 is provided, there is no concern that a falling ball or the like from the upper part of the gaming machine hits. As a result, the static electricity of the falling sphere is reduced by the conductive member 4.
There is no need to worry about flowing into the control circuit on the control board 44 through 7. Further, since the conductive member 47 also serves as the ground of the control board 44, the larger the surface area is, the better. However, it cannot be made too large due to the problem of the falling ball described above. Then, in a limited space on the back of the gaming machine, the one having too much thickness cannot be attached, and the one that is too heavy cannot be attached. Thus, it can be said that a plate-like member having the same shape and the same size as the joining surface of the control unit 17 is most suitable. That is, with the configuration as in this example, the function of the conductive member 47 (the function of blocking noise and the function of discharging static electricity and the like) can be maximized, and the problem of weight increase and size increase is minimized. Can be minimized.

It should be noted that the present invention is not limited to the above-described embodiment, and various modifications and applications are possible. For example, as the conductive member of the present invention, as shown in FIG. 4, a conductive member 70 extending above the control unit and having an extension 71 covering the upper surface of the control unit may be provided. With such a configuration, even if a game ball falls from an upper tank or the like of the gaming machine, the game ball can be prevented from at least being placed on the upper portion of the control unit, and the impact of the dropped ball on the control unit can be reduced. The control unit can be protected without direct application. If the conductive member is made of an iron plate or the like, the extended portion can have considerable elasticity (flexibility), so that the conductive member may be damaged by the impact of the falling ball. Absent.

As a means for attaching the conductive member to the mounting base, a member similar to the fastening member 64 described above may be used so that the conductive member can be attached to and detached from the mounting base with one touch. Further, the conductive member may be attached to the attachment base in a simple locked state. By doing so, the conductive member can be easily removed from the mounting base, the surface of the mounting base can be made bare, and the work of checking the flow of the sphere on the side opposite to the mounting base (for example, inside the winning ball collecting member 33) can be more easily performed. It will be easy. In addition, the concept of the present invention is not limited to the accessory control unit, but can be applied to various control units (for example, a discharge control unit) in a game machine such as a pachinko machine to achieve the same effect.

The present invention is applicable not only to pachinko machines but also to arrange ball machines and slot machines. Further, instead of the above-described caulking member 67, an opening identification seal (a seal that can be recognized when the case is opened) may be used. In addition, the press contact portion of the present invention does not necessarily need to be provided in a state protruding literally, as long as a predetermined contact state can be obtained, for example, it simply faces the control unit side. May be.

According to the gaming machine of the first aspect, in the control unit for controlling any one of the electric appliances,
A control board housing member for housing the control board for executing the control is configured to be transparent, and a conductive member is disposed between the control unit and a mounting base for mounting the control unit on the back side of the gaming machine. The conductive member was electrically connected to the ground electrode of the control board, and was detachably attached to the attachment base. For this reason, in a state where the control unit is removed (that is, a state of the unit alone), all the control boards in the control unit are completely visible without cutting or swaging the control board storage member of the control unit. 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. In particular, in the case of the present invention, since the conductive member is mounted on the mounting base, if the control unit is removed from the gaming machine (mounting base), the control board becomes only the control unit that is completely visible from the front side and the back side. Also, it is possible to more easily confirm the illegal alteration of the control board by the clerk of the game store.

Further, even when the control unit is mounted on the gaming machine, the front surface of the control board is exposed from the back side of the gaming machine, making it easy for the attendant to check the control unit during maintenance and inspection. In addition, when the inside of the control unit becomes easy to see and a conductive member connected to the control unit and grounded is installed, the CPU or the like of the control board may run away (or malfunction) due to noise or the like. Can be prevented with high reliability. In other words, the incidence of noise such as electromagnetic waves from the outside of the unit and the effect of the magnetic field will be effectively blocked by the conductive member,
In addition, since the static electricity or the like of the control board is discharged from the conductive member, malfunction or runaway of the circuit of the control board is prevented. In particular, as described in Claims 3 and 4, when the conductive member is provided with the extending portion or the press-contact portion, the conductive member is provided with the extending portion or the press-contact portion. The surface area is increased, and the effect of the discharge is further improved.

Further, since the conductive member is mounted on the mounting base, the integrated product consisting of the mounting base and the conductive member becomes an independent unit having a function of preventing noise and the like, and the model is changed. Also, only the control unit needs to be replaced, and the unit consisting of the mounting base (the above-mentioned integrated product) can be used in common even if the model is changed. Therefore, the number of replacement parts is small, the replacement work is easy, and the cost is reduced. In addition, when the control unit is removed and inspection or replacement is performed, it is convenient if the conductive member is left attached to the mounting base because the conductive member will not be lost.

According to the second aspect of the present invention, since the conductive member is a plate-like member having the same shape and the same size as one surface of the control unit on the mounting base side, the conductive member is provided between the control unit and the mounting base. However, there is no fear that a falling ball or the like from the top of the gaming machine hits the game machine. Therefore, there is no fear that static electricity or the like of the falling ball flows into the control circuit on the control board through the conductive member. With this configuration, the surface area of the conductive member is the largest in a limited space, and the weight increase is also slight. That is, the function of the conductive member (the function of blocking noise and the function of discharging static electricity and the like) can be sufficiently exhibited, and the problem of weight increase and size increase can be minimized.

According to the gaming machine of the third aspect,
Since the conductive member is provided with an extending portion extending above the control unit, even if the game ball falls from the upper tank or the like of the gaming machine, it is possible to prevent the game ball from being placed at least on the upper part of the control unit. Further, the control unit can be protected without directly giving the impact of a falling ball to the control unit. If the conductive member is made of an iron plate or the like, the extended portion can have considerable elasticity (flexibility), so that the conductive member may be damaged by the impact of the falling ball. Absent.

According to the gaming machine of the fourth aspect,
Since the conductive member and the ground electrode of the control board are in a conductive state by the pressure contact portion provided on the conductive member, for example, another component for connection (for example, a cable and a connector) is attached and the connection is performed. As compared with a configuration in which the steps are performed separately, the assembling work is facilitated, the number of parts is reduced, and low cost can be realized. In particular, claim 4
In the gaming machine described above, when the accessory control unit is assembled to the mounting base, the press-contact portion provided on the conductive member presses against the control board, thereby connecting the conductive member to the ground electrode of the control board. Is performed automatically (without the worker's awareness). For this reason, the assembly cost can be further reduced.

According to the gaming machine of the fifth aspect, the control unit is replaced at the same time when the gaming board is replaced.
Although the frequency of replacement work of the control unit increases, the replacement work can be simplified because the control unit is easily attached and detached. In this case, it is necessary to sufficiently contact the ground electrode of the control board or the circuit conductor electrically connected to the ground electrode and the press-contact portion of the conductive member. Work can proceed quickly. Furthermore, even if the control unit is replaced with a new one, there is no need to replace the conductive member, so that it is possible to provide a gaming machine that satisfies both cost reduction by common use and efficient replacement work. The mounting base may be integrated with the gaming board. However, when there is no place for disposing the mounting base on the gaming board, the mounting base is located at a predetermined position on the front frame side (that is, the main body side of the gaming machine). Needless to say, it may be provided. For example, a configuration may be employed in which an attachment base is attached to the back mechanism panel, and a conductive member is attached to the attachment base. In this case, when replacing the gaming board with a new one, the accessory control unit also needs to be replaced with a corresponding one, so the attachment and detachment frequency of the accessory control unit naturally increases, but in the present invention, The pressure contact part formed on the conductive member and the ground electrode on the control board inside the accessory control unit are configured to come into contact by surface contact. Since there is no need to perform this, work efficiency can be improved.
