JP 2011-189086 A Japanese Patent Laid-Open No. 2003-310979

In recent years, circuit boards that have been used from an ecological point of view have been collected and reused. However, the conventional method of removing or deleting unnecessary management information cannot be reused efficiently because it can be reused only by a company indicated by the remaining management information. It may be possible to reprint management information for reuse by other companies, but it is necessary to secure a new printing space in a narrow circuit board space and to a circuit board on which electronic parts are mounted. It is difficult and unrealistic to print new information.
Furthermore, since the management information is an important matter that supports the reliability of the circuit board and the gaming machine itself, the management information should not be easily changed by fraud.
Therefore, in view of the above circumstances, the present invention has been made as an object to realize a gaming machine that can easily change the setting of management information without impairing reliability and can efficiently reuse a circuit board. It is a thing.

According to the first aspect of the present invention, management of a plurality of locations is described in which an electronic component mounting area in which electronic components are mounted on a circuit board for controlling a game and the like, and a plurality of different types of management information for managing the circuit board are described. In a gaming machine having an information area and a circuit board mounting configuration in which the circuit board is covered with a transparent case member,
The case member is composed of a base member and a lid member,
The circuit board is disposed on the inner surface side of the lid member,
The lid member includes an inner surface portion of a part corresponding to the electronic component mounting region and a gap between the inner surface portion of the circuit board corresponding to the management information region where the electronic component is not mounted and the management information region. Formed to be smaller than the gap with the electronic component mounting region ,
In the lid member, the management information area in which the management information that is not useful among the plurality of management information areas is described on the inner surface of the part corresponding to the management information area is not visible from the outside of the case member. Provide a shielding member to cover,
After covering the circuit board with the case member, the base member and the lid member are caulked and fixed with a caulking member, or the case member must be destroyed to open the case. The case member is sealed by firmly engaging or adhering to the lid member, and the movement of the shielding member is prohibited.

According to this, effective management information and invalid management information can be clearly differentiated in visibility by using the shielding member provided on the inner surface of the lid member. In addition, since the gap between the management information area and the shielding member provided on the inner surface of the lid member is smaller than the gap between the inner surface of the lid member corresponding to the electronic component mounting area and the electronic component mounting area, the management information to be hidden Can be hidden more reliably.
Furthermore, since the shielding member is provided on the inner surface of the case member and the case member is sealed, contact and interference with the shielding member cannot be performed unless the case member is opened, and the valid / invalid management information once set is incorrect. Therefore, the change is accompanied by a certain difficulty such as opening the case member, so that the management information and the reliability of the gaming machine are not impaired.
As a structure for sealing the case member, the base member and the cover member are fixed by caulking with a caulking member (caulking pin), or the two are firmly engaged or bonded to each other, and the case is not destroyed for opening. Since the trace remains on the case member when the case member is unfairly opened, fraud can be easily found.
And other management information is not removed from the circuit board as in the past, and since the shielding member is provided on the case member side, when the circuit board is properly reused, the circuit board is properly replaced with a new case. By transferring to, effective management information can be changed, and it is not necessary to leave a trace that was previously used on the circuit board, so that the circuit board can be easily reused.

The invention according to claim 2 is the gaming machine according to claim 1,
The circuit board is assembled to the lid member such that a mounting surface having the electronic component mounting area and the plurality of management information areas is covered with the lid member .

  According to this, the management information area in which the management information that is not useful can be described can be suitably covered.

  Among the control boards, the main control board 30 is composed of a circuit board on which a large number of electronic components such as a CPU, ROM, and RAM constituting the microcomputer are mounted. The pachinko machine is program-controlled by the microcomputer and is housed in a case member. Thus, it plays a role of preventing an illegal act such as a program being changed due to a change in ROM or the like.

By the way, each control board is shared among a plurality of companies in the same group. For this reason, a plurality of pieces of management information corresponding to companies that share the board are described in advance on the control board. When the control board is assembled to the case member, only useful management information is visible from the outside of the case member according to the company used, and unnecessary information is hidden.
Hereinafter, a first embodiment to which the present invention is applied will be described using an assembly structure of a main control board 30 to a case member.

  As shown in FIGS. 3 and 4, the main control board 30 has a rectangular shape with a long lateral width in the left-right direction. The board surface of the main control board 30 has an electronic component mounting area 30a where a large number of electronic components (not shown) such as the CPU, ROM, RAM, and connectors 301 are mounted, and the main control board 30 along the lower edge of the board. And a management information area 30b in which management information such as a management number is described.

In the illustrated example, the management information area 30b is provided with four areas. In each area, the names of two companies that share the board, management numbers corresponding to the respective companies, and the like are described. The arrangement of the example is a company name, a company name, a management number, and a management number.
Then, in the management information area 30b, the name of one company that uses the board 30 and the one management number corresponding to the company are left, and the area where the other company name and the other management information are described is respectively displayed by the shielding member 40. The cover is hidden and cannot be viewed from outside the case.

  The shielding member 40 is a thin opaque synthetic resin plate and is adapted to the size and shape of the person in the management information area 30b. The shielding member 40 has an adhesive applied to the back surface, and is thus adhered to the front surface of the management information area 30b so as to cover up unnecessary company names and management numbers. In the example shown in the figure, an unnecessary company name and management number are hidden by attaching a shielding member 40 every other area from the left end area.

The case member 5 includes a shallow rectangular container-shaped base member 5b that receives the main control board 30 from the back surface side thereof, and a shallow square container-shaped lid member 5a that covers the main control board 30 from the front surface side thereof.
The base member 5b is made of an integrally molded product of a transparent synthetic resin and has a bottom wall portion 50 that forms a bottom surface of a substantially rectangular plate. The base member 5b protrudes to the surface side of the bottom wall 50 at the upper edge and the lower edge, which are the long sides of the bottom wall 50, and bends at a substantially right angle in the lateral direction (left direction in FIG. 3). A plurality of substantially L-shaped locking claws 501 are provided at predetermined intervals.

The base member 5b is formed with a side wall 51 (left side in FIG. 3, hereinafter referred to as a left side wall) 51 on the side of the locking claw 501 in the bending direction. A pair of upper and lower tongue-like projecting pieces 502 projecting to the left lateral direction along the bending direction are provided.
On the other hand, on the right side wall 52 of the base member 5b, a pair of upper and lower caulking bosses 503 used for connecting and fixing the base member 5b and the lid member 5a are formed at the upper end position and the lower end position, respectively.

Similarly to the base member 5b, the lid member 5a is made of an integrally molded product of transparent synthetic resin. The lid member 5a has a rectangular front wall portion 55 that covers the surface of the main control board 30, and a wall-shaped peripheral wall 57 that bends substantially perpendicularly from the upper edge, lower edge, and left and right side edges of the front wall portion 55 on the outer periphery. Is provided.
In the lid member 5a, the four corners of the main control board 30 are screwed and fixed to a plurality of fastening portions 551 formed by screw holes provided in the vicinity of the four corners of the front wall portion 55, and the main control is performed on the inner surface side of the lid member 5a. The substrate 30 is assembled.

The front wall portion 55 of the lid member 5 a has a shape in which the general portion excluding the upper end portion and the lower end portion protrudes greatly toward the surface side, and does not interfere with the electronic components mounted on the surface of the main control board 30.
The upper end portion of the front wall portion 55 with a small protrusion compared to the general portion is provided with a plurality of connector insertion holes corresponding to the plurality of connector portions 301 standing on the upper end of the surface of the main control board 30. It can penetrate. Reference numeral 556 in FIG. 3 denotes an auxiliary plate that is set to allow insertion of small connectors among the connectors 301 of the main control board 30, and is formed on the upper end portion of the front wall portion 55 by the auxiliary plate 556. Cover the gap between the large connector insertion hole and the small connector.
The lower end portion 550 of the front wall portion 55 corresponds to the management information area 30b of the main control board 30, and the amount of protrusion of the lower end portion 550 is reduced because there is no electronic component in the management information area 30b. By reducing the protruding amount of the lower end portion 550 in this way, the gap between the management information area 30b and the inner surface portion of the lower end portion 550 is reduced, so that the visibility of management information not hidden by the shielding member can be improved.

  The upper wall portion and the lower wall portion of the peripheral wall 57 of the lid member 5a are provided with a plurality of engaging portions 552 that can be engaged with each of the locking claws 501 of the base member 5b on the inner surface side thereof. Is provided. The engaging portion 552 can engage and lock the L-shaped bent tip of the locking claw 501 in the lateral direction.

The left side wall of the peripheral wall 57 of the lid member 5a is provided with a pair of upper and lower rectangular cylindrical fitting holes 571 into which the protruding pieces 502 of the left side wall 51 of the base member 5b can be fitted.
A pair of upper and lower bosses 554 corresponding to the caulking bosses 503 at the right end of the base member 5b are formed on the right side wall 58 of the lid member 5a.

  In order to assemble the base member 5b and the lid member 5a, first, the base member 5b is shifted to the right side and the lid member 5a is alternately shifted to the left side. The upper and lower wall portions of the peripheral wall 57 and the upper and lower end edges of the base member 5b are brought into contact with each other in the facing direction (the direction of arrow T in FIG. 3). At this time, the engaging claws 501 at the upper and lower end edges of the base member 5b are positioned between the engaging portions 552 of the upper and lower wall portions of the lid member 5a, and the protruding pieces 502 of the base member 5b are provided. The base member 5b and the lid member 5a are combined so as to face each fitting hole 571 of the lid member 5a.

Next, the base member 5b and the lid member 5a are moved relative to each other in the left-right lateral direction (in the direction of arrow S in FIG. 3) along the wall surface of the bottom wall portion 50 of the base member 5b. 501 is fitted and locked to each engaging portion 552 of the lid member 5a, and each protruding piece 502 of the base member 5b is fitted into each fitting hole 571 of the lid member 5a, and the left side wall of the base member 5b and the lid member 5a. 51 and 57 and the right side walls 52 and 58 are brought into contact with each other, and the caulking bosses 503 of the base member 5b and the bosses 554 of the lid member 5a are overlapped.
The base members 5b and the lid member 5a are assembled and fixed by caulking and fixing the bosses 503 and 554 with caulking members made of metal pins press-fitted into the bosses 503 and 554.

When viewed from the front, the main control board 30 and the case member 5 assembled in this way are shield members for the management information area 30b of the main control board 30 through the lower end portion 550 of the front wall portion 55 of the case member 5. The company name and management number of management information not hidden by 40 can be clearly seen.
By using the shielding member 40, effective management information and invalid management information can be clearly differentiated in terms of visibility. Further, since the shielding member 40 is provided on the plate surface of the main control board 30, only invalid management information can be surely hidden, and misreading and misidentification of information can be prevented.

Further, since the shielding member 40 is provided on the inner side of the case member 5 and the case member 5 is caulked and sealed with the base member 5b and the lid member 5a, contact and interference with the shielding member 40 by the operator are not caused by the case. It cannot be performed unless the member 5 is opened, and it is difficult to change the valid / invalid management information once set by mistake or intentionally (malicious), and the case member 5 must be opened for the change. Therefore, effective management information and the reliability of the gaming machine are not impaired.
Further, the main control board 30 must seal the case member 5 from the viewpoint of preventing an illegal act such as replacement with an illegal ROM, and the shielding member is adhered to the board and installed inside the case. It is also advantageous with respect to preventing 40 unauthorized manipulations.

  The case member 5 has its base member 5b and lid member 5a engaged with their locking claws 501 and engaging portions 552, the projecting piece 502 and the fitting hole 571, and both caulking bosses 503 and 503. Since the 554 is fixed with caulking, it is tightly sealed, and if the main control board 30 is illegally operated, the case must be destroyed, and if the case member 5 is illegally opened, the trace is left on the case member 5. Since it remains, it is easy to detect fraud.

  Since the main control board 30 does not remove unusable management information from the board as in the prior art, it can be easily changed so that other companies can use it properly. That is, the effective control information is changed by destroying the case member 5, taking out the main control board 30, removing the shielding member 40, changing the position, and sealing the main control board 30 to the new case member 5. Thus, the control board can be easily reused.

In this embodiment, the shielding member provided on the control board may be an opaque paper sealing member or a sealing member made of a thin opaque synthetic resin sheet. According to these, since the thickness of the shielding member can be further reduced, the protruding amount of the lower end portion 550 can be set further smaller, and the visibility of management information that is not hidden is improved.
Further, as shown in FIG. 5, as a shielding member, a shielding member 41 having a sandwiching portion 411 whose lower edge portion is folded back into a substantially U-shaped cross section is used, and the unnecessary portion of the management information area 30 b of the substrate 30 is covered by the general portion 410. At the same time, the lower edge of the substrate 30 may be press-fitted into the holding portion 411 and the shielding member 41 may be installed on the substrate 30.

  Further, as another shielding member, a clip portion may be provided on the back surface of the lower end portion of the opaque synthetic resin plate, and the clip portion may be engaged with the circuit board. Furthermore, there is no problem even if the shielding member is attached to the circuit board by a known structure such as fitting, brazing, and screwing. It may be attached so long as it can withstand vibration even when the circuit board and the pachinko machine are being transported or subjected to installation work, and can maintain the shielding state without the shielding member being displaced or detached.

  A second embodiment of the present invention will be described with reference to FIGS. The assembly structure of the substrate of this embodiment is configured such that an area in which unusable management information of the substrate is described is covered with a shielding member provided on the inner surface of the case member so that it cannot be seen from the outside of the case. The basic configuration of the present embodiment is substantially the same as that of the first embodiment except for the configuration related to the installation of the shielding member, and the configuration of the present embodiment will be described focusing on the differences. In the drawings, the same members are denoted by the same reference numerals.

  As shown in FIGS. 6 and 7, the shielding member 42 is made of a thin opaque synthetic resin plate, and an adhesive is applied to the surface thereof. The shielding member 42 covers a region where unnecessary management information is written on the inner surface of the lower end portion 550 of the front wall portion 55 of the lid member 5a of the case member 5 facing the management information region 30b of the main control board 30. It is pasted to hide. For example, in the illustrated example, a plurality of shielding members 42 are adhered to the inner surface portion of the lower end portion 550 at the front positions of the information so as to cover the second and fourth management information from the left.

  After the shielding member 42 is installed inside the lid member 5a of the case member 5 as described above, the main control board 30 is assembled inside the lid member 5a, as in the first embodiment, and the base member of the case member 5 is assembled. 5b and the lid member 5a are assembled and sealed. That is, the main control board 30 is assembled by screwing and fixing the four corners to the back surface of the lid member 5a. After the substrate 30 is assembled, both the members 5a and 5b are brought into contact with each other in the front and back direction (the direction of arrow T in FIG. 6) with the base member 5b and the lid member 5a of the case member 5 being alternately shifted left and right.

Next, both members 5b and 5a are moved relative to each other in the lateral direction (in the direction of arrow S in FIG. 6), and the respective locking claws 501 of the base member 5b are fitted and locked to the respective engaging portions 552 of the lid member 5a. The projecting pieces 502 of the base member 5b are fitted into the fitting holes 571 of the lid member 5a, and the left side walls 51 and 57 and the right side walls 52 and 58 of the base member 5b and the right side walls 52 and 58 are brought into contact with each other. At the same time, the bosses 503 for caulking of the base member 5b and the bosses 554 of the lid member 5a are overlapped.
The base members 5b and the lid member 5a are assembled and fixed by caulking and fixing the bosses 503 and 554 with caulking members made of metal pins press-fitted into the bosses 503 and 554.

According to this embodiment, there exists an effect similar to the said 1st Embodiment. It is desirable that the distance between the management information area 30b of the control board 30 and the inner surface of the lower end portion 550 of the lid member 55 of the case member 5 on which the shielding member 42 is installed be as small as possible.
Moreover, in this embodiment, since the shielding member 42 is provided on the case member 5 side, when the substrate 30 is properly reused, it is not necessary to leave a trace that was previously used on the substrate 30 and is preferably reused. it can. Further, if the substrate 30 or the shielding member 42 is illegally operated (changed), the case member 5 must be destroyed in order to seal it, and the fraud can be easily detected.

As another structure of the second embodiment in which the shielding member is provided on the inner surface side of the case member, as shown in FIG. 8, a holding portion 60 is provided on the inner surface of the lower end portion 550 of the front wall portion of the lid member 5a. You may make it attach the shielding board 43 by.
On the inner surface of the lower end portion 550, a pair of left and right holding portions 60 extending in the vertical direction is provided with an interval corresponding to the width of the shielding member 43 made of an opaque synthetic resin plate. The holding portion 60 is integrally formed on the inner surface of the lower end portion 550, and has a base portion 601 rising from the inner surface of the lower end portion 550 and a front end portion 602 orthogonal to the front end edge thereof. A groove extending in the vertical direction with the inner surface and capable of press-fitting the side edge of the shielding member is formed. Further, the left and right holding portions 60 are formed so that the grooves formed by the inner surface face each other. Furthermore, the lower ends of the left and right holding parts 60 reach the inner surface of the peripheral wall 57 of the lid member 5 a, and the lower ends of the grooves are closed by the peripheral wall 57. It is desirable that the holding portion 60 at the intermediate position has a substantially T-shaped cross section so as to hold the side edges of the left and right shielding members 43 (see FIG. 8 or the right side in FIG. 9). See holding part).

  And in order to attach the shielding member 43, the left and right side edge portions are press-fitted downward into the respective grooves of the left and right holding portions 60 on the inner surface of the lower end portion 550 of the lid member 5a from the upper end openings thereof. The shielding member 43 is attached so as to overlap the inner surface of the lower end portion 550 of the lid member 5a. Of course, after attaching the control board 30 to the lid member 5a and assembling the lid member 5a and the base member 5b, the case member 5 is sealed.

  Furthermore, in another structure of the second embodiment, as shown in FIG. 9, the shielding member 43 may be caulked and fixed to the inner surface of the lower end portion 550 of the lid member 5a. FIG. 9 is a diagram showing a horizontal cross section in a state where the shielding member 43 is held on the inner surface of the lower end portion 550. The shielding member 43 held by the pair of left and right holding portions 60 so as to overlap the inner surface of the lower end portion 550. Are fixed by caulking with a metal caulking pin P that is formed by passing through the lower end portion 550 and the shielding member 43 in series. The caulking pin P is caulked and fixed by crushing both ends protruding from the lower end portion 550 and the shielding member 43 and expanding the diameter.

If the shielding member 43 is fixed by caulking in this way, it is not necessary to seal the case member with respect to prevention of unauthorized operation (movement, etc.) to the shielding member 43. Therefore, the present configuration is used without sealing the case member to a board that does not cause an illegal act to the board such as ROM exchange, for example, the sound lamp control board 32, the power board 34, the power distribution board, and various relay boards. be able to.
In order to operate the shielding member 43 in an unauthorized manner, the caulking pin must be cut and the caulking fixing must be released, so that the injustice can be easily detected.

  Next, a third embodiment of the present invention will be described with reference to FIGS. In the present embodiment, the board assembly structure of the present embodiment is configured so as to cover an area where unusable management information of the board is described with a shielding member provided on the outer surface of the case member. The basic configuration of the present embodiment is substantially the same as that of the first embodiment except for the configuration related to the installation of the shielding member, and the configuration of the present embodiment will be described focusing on the differences. In the drawings, the same members are denoted by the same reference numerals.

As shown in FIGS. 10 to 12, a holding portion 61 is provided on the outer surface of the lower end portion 550 of the front wall portion of the lid member 5 a of the case member 5, thereby attaching the shielding plate 44.
On the outer surface of the lower end portion 550, a plurality of a pair of left and right holding portions 61 extending in the vertical direction are provided at intervals of the horizontal width of the shielding member 44 made of an opaque synthetic resin plate. The holding portion 61 is integrally formed on the outer surface of the lower end portion 550, and has a base 611 that stands up from the outer surface of the lower end portion 550 and a front end portion 612 that is orthogonal to the front end edge, and has a substantially L-shaped cross section. It has a basic configuration having a groove extending in the vertical direction with the outer surface and capable of press-fitting the side edge of the shielding member 44. The left and right holding portions 61 are provided such that grooves formed by the outer surfaces face each other. Furthermore, the lower ends of the grooves of the left and right holding portions 61 are opened downward. It is desirable that the holding portion 61 at the intermediate position has a substantially T-shaped cross section so as to hold the side edges of the shielding members 44 on both the left and right sides, and the groove is provided on both the left and right sides (see the holding portion on the right side in FIG. 12). .

  And the shielding member 44 press-fits the right and left side edges along the outer surface of the lower end portion 550 of the lid member 5a into the respective grooves of the left and right holding portions 61 upward from the lower end openings. The shielding member 44 is attached so as to overlap the outer surface of the lower end portion 550 of the lid member 5a.

  Further, as shown in FIG. 12, in the state where the shielding member 44 is held on the outer surface of the lower end portion 550, the shielding member 44 is caulked by a metal caulking pin P in which the lower end portion 550 and the shielding member 44 are penetrated in series. Fix it. The caulking pin P is caulked and fixed by crushing both ends protruding from the lower end portion 550 and the shielding member 44 and expanding the diameter.

According to this embodiment, there exists an effect similar to the said 1st Embodiment. It is desirable that the distance between the management information area 30b of the control board 30 and the outer surface of the lower end portion 550 of the lid member 55 of the case member 5 on which the shielding member 44 is installed be as small as possible.
Further, since the shielding member 44 is provided on the case member 5 side, when the substrate 30 is properly reused, it is not necessary to leave a trace that the substrate 30 has been used before, and can be suitably reused. Further, if the board 30 or the shielding member 44 is manipulated illegally, the case member 5 must be broken or the caulking pin P of the shielding member 44 must be broken in order to seal it. Can be found.

Further, if the shielding member 44 is fixed by caulking, there is no need to seal the case member with respect to prevention of unauthorized operation (movement, etc.) to the shielding member 44. Therefore, the present configuration is used without sealing the case member to a board that does not cause an illegal act to the board such as ROM exchange, for example, the sound lamp control board 32, the power board 34, the power distribution board, and various relay boards. be able to.
In order to operate the shielding member 44 illegally, the crimp pin P must be broken to release the crimp fixing, so that the unauthorized operation can be easily detected.
