Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a board box for accommodating a control circuit board of a gaming machine.

[0002]

2. Description of the Related Art In a conventional gaming machine, for example, a pachinko gaming machine, a control circuit such as an accessory control device for controlling a game of the gaming machine or a ball ejection control device for controlling a ball ejection device is provided on the back side of the gaming machine. Is provided in the box.

[0003] A board box is used to house a control circuit board on which a large number of various electronic components such as ICs (integrated circuits) and resistors are mounted in a resin or metal box to prevent a short circuit or the like and dust such as dust. Is protected from intrusion,
It can be mounted on the back side of a main body frame (front frame) of a gaming machine or a back mechanical base board or a game board as a base frame.

For example, in the accessory control device, a CPU, a ROM (memory), a RAM (memory), and the like are provided in a control circuit, and game control is performed according to a program stored in the ROM, and a big hit or the like is performed. Is also controlled here.

[0005] The board box is generally a box body in which an upper lid member and a base member are overlapped, and a connector portion for electrically connecting to other various devices is provided so as to be exposed from the box. By inserting various wirings into the connector section, it is possible to control each of them.

[0006] The wrongdoing with respect to the board box is performed by removing the upper cover member and removing the R provided on the opened control circuit board.
By replacing electronic components such as OM or rewriting data (for example, setting the jackpot probability higher than normal ones), for example, a jackpot may appear more frequently than in normal game control. Unauthorized game control was performed.

For this reason, in the substrate box, once opened, a sealing seal is attached to the joint between the upper lid member and the base member so as to indicate that the substrate box has been opened.
Alternatively, the surface of the board box is made of clear resin so that the state of the housed control circuit board can be seen from the outside.

[0008]

However, in the conventional board box, since the upper cover member and the base member are structurally assembled only with screws, it is easy to remove the upper cover member and open the box body. Also, even if a seal is put on the joint between the top cover member and the base member, this is effective for an easy cheating person, but is a very specialized cheating person, for example, a fake sealing seal or In fact, it is no longer effective for those who have special release materials.

In order to prevent such misconduct, it is conceivable to make the board box unopenable or very difficult to open. However, in a game arcade, the game machine once installed is punched out. Public institution (police, etc.)
Inspection of whether the board is an illegal board is performed. As the inspection content, an inspection is performed in which the program data stored in the ROM is read by a data loader and compared with an authorized ROM. In this case, if the board box cannot be opened as described above, the inspection is performed. I can no longer do it. For this reason, it is conceivable that the substrate box is broken and opened, but if the substrate box is broken, it cannot be reused after the inspection.

Therefore, an object of the present invention is to provide a gaming machine which can prevent unauthorized opening by using a mechanism for opening by sliding, rather than a structure for opening and opening an upper lid member in which a board box itself is placed on a base member. To provide a substrate box.

[0011]

In the vicinity of 54 to 57, polymerization bonding portions 50 to 53 and 54 to 5
An identification symbol such as a number is displayed corresponding to 7.

Although the identification symbol is not shown, the overlapping joint portion 50 is arranged in the order of proximity to the tip of the upper lid member 26, that is, the end in the closing slide direction.
To 53, 54 to 57, for example, the polymerized bonding portion 5
The identification symbol of 1 corresponding to 0, 54 is the overlapped bonding portion 51,
55, the two overlapping symbols correspond to the overlapping bonding portions 52, 56.
Is displayed, and the identification code of 4 is displayed corresponding to the overlapping portions 53 and 57. The identification symbol determines the order of sealing and opening when inspecting electronic components such as the ROM 28 of a public organization. The identification symbol must be printed or stamped (including a molded display), or a seal printed with the identification symbol must be attached. And so on.

Incidentally, the base member 25 is provided with a one-touch type stopper for a hook of a mounting portion of the rear mechanical base panel 10 for mounting on the rear mechanical base panel 10.

Next, the assembling of the board box 15 and the assembling to the game machine will be described. The control circuit board 27 is aligned with the bottom 33 of the base member 25 and screwed to the fixing part 34. The auxiliary wall 41 is attached to the insertion groove 42 of the support wall 36 of the peripheral walls 35a and 35b of the base member 25.

The overlapped joints 50 to 53, 5 of the upper lid member 26
One-way screws 65 that can be turned only in the tightening direction are temporarily fixed to the through holes 64 of the upper coupling portions 61 of 4 to 57 so that the tips of the one-way screws 65 do not project from the through holes 64 to the lower surface.

In this case, in order to set the depth of the one-way screw 65, an adjusting mechanism such as a stopper for adjusting the tightening depth is provided on a driver tool for tightening the one-way screw 65, and the one-way screw 65 is temporarily fixed. It is good to Once the one-way screw 65 is once tightened, it cannot be returned to its original state. However, in this case, the one-way screw 65 can be temporarily fixed to an appropriate depth, and the temporary fixing can be easily performed.

Both ends of the top plate 43 of the upper lid member 26 are connected to the protective wall portions 38 of the peripheral walls 35a and 35b of the base member 25.
Of the top plate 43 and the edge wall 44
a, 44b are connected to the supporting walls 36 of the peripheral walls 35a, 35b.
, The upper lid member 26 is slid toward the peripheral wall 35c to a predetermined position, and the upper lid member 26 is closed. When the upper lid member 26 is closed, the overlapped joints 50 to 53, 54 to 57
The upper joints 61 on the upper lid member 26 overlap with the corresponding lower joints 63 on the base member 25 side.

In this state, the polymerization bonding portions 50 to 53,5
4 to 57, the overlapping portions 50 and 54 of the identification code 1
Are securely fastened to the lower connecting portion 63 with the one-way screws 65 temporarily fixed to the upper connecting portion 61, respectively.
Stick.

Since the one-way screw 65 sealing the overlapped joints 50 and 54 has its head surrounded by the embedment hole 66 of the upper joint 61, the one-way screw 65 is forcibly turned in a loosening direction by, for example, a pliers. Actions can be prevented.

Thereafter, on the surface of the substrate box 15, that is, on the surface of the top plate 43 of the upper lid member 26, respective specifications such as a game machine maker name, a model name, a voltage, a capacity, and a precautionary note are written on a transparent seal or the like. It is possible to write the model name display slip 80 and the board control number including the manufacturer's symbol on a predetermined seal or the like, and to make a statement proving that a public organization has opened the board box 15 properly at the time of inspection. An inspection history record 81 provided with columns for describing the inspection history such as the number of inspections, the number of inspections, the date of inspection, and the inspection mark is attached.

The model name display slip 80 is attached to the top end of the top plate member 43 of the top cover member 26, and the inspection history report 81 is attached to the overlapped joints 50 to 53 and 54 to 57 of the top plate unit 43 by sticking. .

In this case, the model name display form 80 is formed by printing or embossing (including molding display) the game machine manufacturer's name and specifications on a plate made of resin or the like, and bonding it to the top plate 43 of the upper lid member 26. Alternatively, a mounting portion such as a fitting groove may be formed in the top plate portion 43 and mounted. Alternatively, the gaming machine manufacturer name and each specification may be stamped on the top plate 43 in advance.

In the inspection history report 81, a seal provided with a column for describing the inspection history and the like is attached to a plate made of resin or the like.
A mounting portion such as a fitting groove to which the plate can be attached and detached may be formed on the top plate portion 43 of the upper lid member 26 and attached. Further, explanations such as procedures for opening and sealing at the time of inspection may be printed or stamped on a seal or a plate. When a seal is used, a special seal that leaves a trace when peeled off may be used.

In the column of the number of inspections in the inspection history record 81, the identification symbols 1, 2, 3, 4 of the overlapped joints 50 to 53, 54 to 57 displayed on the top plate 43 of the upper lid member 26 are shown. In response to the above, printing of the first, second, third, and fourth displays and the like are performed in advance. As described above, the polymerization bonding portions 50 to 53, 54 to
If the column of the inspection history is made to correspond to the identification symbol of 57, the sealing order of the overlapped joints 50 to 53 and 54 to 57 is determined, and the work at the time of inspection becomes easy. The bonding state of the polymerized bonding portion can be accurately collated.

Incidentally, the model name display form 80 and the inspection history report 81
May be attached to the inner surface of the top plate 43 of the upper lid member 26, that is, the model name display slip 80 and the surface of the inspection history report 81 face the surface (outer surface) of the top plate 43. In this case, the model name display form 80 and the inspection history 81 do not become dirty and the display is not easily seen by dust and the like, and the model name display form 80 and the inspection history 81 are peeled or damaged. There is no such thing.

The board box 15 assembled in this manner is mounted at a predetermined mounting position on the rear mechanical base panel 10 of the gaming machine as shown in FIG.

The base member 25 of the substrate box 15 is aligned with the surface of the rear mechanical base board 10 at a predetermined mounting position, and a one-touch type stopper is engaged with the hook at a predetermined position of the rear mechanical base board 10 and fixed. In this case, the control circuit board 2
7 is the ball discharge control device 13
The mounting position is determined so that it comes to the side.

After this mounting, the display control device 12, the ball discharge control device 13, and the connector ends of the wiring cord groups 17 to 20 from various electric devices are connected to the connector section 30 in the connection area 31 of the wiring cord group on the control circuit board 27. Are fitted and connected.

Since the overlapped joints 50 to 53 and 54 to 57 are located deeper than the top plate 43 of the upper lid member 26, the wiring cord groups 17 to 20 are connected to the connector 30 of the connection area 31.
When connecting to or disconnecting from the
To 53 and 54 to 57 are hardly entangled with the wiring.

As described above, the assembling and assembling are performed. When the public organization inspects the ROM 28 of the control circuit board 27 in the board box 15, the board box 15 is removed from the rear mechanical base board 10 of the gaming machine. Inspection is carried out with the device removed or attached to the back mechanism base plate 10.

When the inspection is performed with the substrate box 15 removed, or when the inspection is performed with the substrate box 15 attached, the identification of the overlapped joints 50 to 53 and 54 to 57 fixed by the one-way screw 65 is performed. The upper connecting portion 60 and the lower connecting portion 62 of the overlapping portions 50 and 54 of symbol 1 are cut with a nipper or the like, and the overlapping portions 50 and 54 are removed. In this case, both the upper connecting portion 60 and the lower connecting portion 62 are surely cut.

When the overlapped portions 50 and 54 are removed, when the upper lid member 26 is slid in the opening direction, the upper lid member 26, that is, the substrate box 15 is opened.

When the board box 15 is opened, the inspection is performed by removing the ROM 28 of the control circuit board 27.

When the inspection is completed, the ROM 28 is mounted on the control circuit board 27, and the upper cover member 26 is closed as described above. At this time, the upper joints 61 of the unjoined overlapping joints 51 to 53 and 55 to 57 of the identification symbols 2 to 4 overlap with the corresponding lower joints 63 respectively.

In this state, the overlapping bonding portion 5 of the identification code 2
The one-way screws 65 temporarily fixed to the upper coupling portions 61 of the first and the first 55 are tightened to the lower coupling portion 63, and the overlapping coupling portions 51 and 55 are coupled and fixed.

Thereafter, the inspector enters the date of the inspection and stamps the inspection mark or the like in the first entry column of the number of inspections in the inspection history sheet 81 of the top plate 43 of the upper lid member 26, and performs the inspection. Is completed, and when the board box 15 is removed from the back mechanism base board 10, the wiring cord groups 17 to 20 are connected to the connector section 32 of the connection area 33 of the control circuit board 27 by attaching to the back mechanism base board 10. Complete.

On the other hand, as a wrongdoing, the board box 15
Is illegally opened, and the ROM 28 of the control circuit board 27 is replaced with an unauthorized ROM, or the data in the ROM 28 is rewritten to generate a big hit frequently.

In this misconduct, it is assumed that the upper connection portion 60 and the lower connection portion 62 of the overlapped bonding portion which are properly fixed are cut, the overlapped connection portion is removed, and the board box 15 is opened. However, this can be found by checking the state of the board box 15 at the time of maintenance and inspection of the gaming machine at the amusement store or at the time of fixing a clogged ball or the like of the gaming machine during business hours.

In order to mount the board box 15 on the back of the game machine, the overlapped joints 50 to 53, 54 from the back side of the game machine.
To 57, and the upper lid member 2 of the substrate box 15
In addition, the identification symbols of the overlapped joints 50 to 53 and 54 to 57 are displayed on the top plate 43 of the sixth and the inspection history corresponding to the identification code is provided in the inspection history 81 attached to the top plate 43. Therefore, by checking the identification symbol and the inspection history, it is possible to easily check which of the overlapped joints that have been properly fixed and whether or not the fixed overlapped joint is the correct one. It is easy to check the state of the upper connecting portion 60 and the lower connecting portion 62.

For this reason, when the front frame 1 of the gaming machine is opened, if the regular overlapped joint is cut off, this can be found immediately.

Further, in order to make it difficult to detect a fraud, only the upper connecting portion 60 is cut and the substrate box 15 is opened without removing the overlapped joint portion, or the upper connecting portion 60 is hidden so as to hide the cut portion. It is conceivable to open the substrate box 15 by cutting only the lower connection portion 62 on the lower side without cutting the connection portion 60, but the substrate box 15 cannot be opened by such a method.

That is, the upper lid member 26 is
To allow the substrate box 15 to be opened and closed, and to the base member 25, the overlapped joint portions 50 to 5 arranged in a row in the sliding direction.
Since the stopper 70 is provided at a position in the opening slide direction with respect to the lower coupling portions 63 of 3, 54 to 57, for example, when only the lower coupling portion 62 of the fixed overlapping coupling portion is cut, FIG. As shown in FIG. 7, the lower joint portion 63 of the overlapped joint portion remains fixed to the upper joint portion 61 similarly to the upper lid member 26. Therefore, when the upper lid member 26 is slid in the opening direction, the lower joint portion 63 is integrated with the upper lid member 26. The lower connecting portion 63 contacts the stopper 70 in the opening sliding direction, and prevents the upper lid member 26 from sliding. Thereby, unauthorized opening of the board box 15 can be prevented. However, FIGS. 6 and 7
Indicates only one polymerized bond for explanation.

Further, the stopper 71 is provided on the upper lid member 26 at a position in the closing sliding direction with respect to the upper connecting portions 61 of the one row of the overlapping connecting portions 50 to 53 and 54 to 57 along the sliding direction. When only the upper connecting portion 60 of the fixed overlapping portion is cut off, the upper connecting portion 61 of the overlapping portion remains fixed to the base member 25 to the lower connecting portion 63, so that the upper lid member 26 is connected to the lower connecting portion 63. When the upper cover member 26 is slid in the opening direction, the stopper 71 of the upper cover member 26 hits the upper joint portion 61 integrated with the base member 25, and the upper cover member 26
Block slides. Thereby, the substrate box 15
Can be prevented from being illegally opened.

On the other hand, the overlapping portions 50 to 53 and 54 to 57 are arranged in a line along the sliding direction, and the sealing order of the overlapping portions 50 to 53 and 54 to 57 is determined by the closing order of the upper lid member 26. It is determined in the order close to the end in the slide direction and sealed (fixed) at the time of shipment from the manufacturer or at the time of inspection, so that only the lower connecting portion 62 of the overlapped bonding portions 50 and 54 fixed as shown in FIGS. if you did this,
When the upper lid member 26 is slid in the opening direction, the upper lid member 2
The lower joint portion 63 of the overlapped joint portions 50 and 54 integral with 6 corresponds to the lower joint portion 63 of the adjacent overlapped joint portions 51 and 55.
