Abstract

PROBLEM TO BE SOLVED: To prevent the exfoliation of a sealing seal, and to further enhance the protection of an electronic circuit board by constituting a structure which does not allow the direct contact of the sealing seal which is pasted so as to straddle a clearance between members for accommodating the electronic circuit board.SOLUTION: Since a sealing seal 260 is accommodated in a hollow part 240 and made not to be touched from the outside, an illegal action such as the re-pasting of the sealing seal 260 once again by exfoliating the sealing seal further cleanly by using a solvent, and performing the exchange, falsification or the like of an internal electronic part becomes impossible. Since auxiliary members 254, 256 pasted with the sealing seals 260 are joined to a cover-side hollow forming part 242 and a base-side hollow forming part 244 by ultrasonic welding, respectively, the sealing seal 260 can function as a role for performing sealing with respect to a closed cover part 222 and a base part 224.

Description

  The present invention accommodates an electronic circuit board on which electronic components are assembled in a specific area, and at least two or more occlusions that block the specific area so that operations on the electronic circuit board are restricted. The present invention relates to a circuit board case configured by assembling members.

  The electronic circuit board mounted on the gaming machine is basically attached to the back surface of the gaming board or the like while being accommodated in the circuit board case.

Hereinafter, a main control board will be described as an example of a representative electronic circuit board.

  The main control board is placed on a base plate that constitutes a part of the circuit board case, and a box-type upper lid is attached and sealed so as to surround the periphery of the base board. As a result, the main control board is accommodated by the base plate and the upper lid.

  A seal seal is stuck between the base plate and the upper lid so as to straddle them. This seal seal is no different from the well-known seal seal in that the trace remains when it is peeled off, and after the base plate and the upper lid are sealed once, A trace of opening can be left.

  In recent years, there is a seal seal with an RFID function added (see Patent Document 1). For example, an IC tag composed of an antenna and an IC chip is a typical example. When an external radio wave is received, power is generated by electromagnetic induction and information stored in the IC chip is output.

  The information stored in the IC chip of the IC tag provided on the seal sticker is collated with the identification code information of the main control board accommodated in the circuit board case. For example, only the main control board is peeled off after the seal sticker is peeled off. When exchanged, it is possible to recognize unauthorized exchange by comparing information stored in the IC chip with identification code information set on the main control board.

  Further, when the seal seal is cut with a blade or the like, the antenna is cut. In this case as well, for example, an error occurs in a regularly executed collation program, so that it is possible to recognize that there is fraud.

  A rectangular groove 222C having a depth smaller than the thickness of the ceiling 222B is formed on the surface of the ceiling 222B of the closing cover 222. The rectangular groove 222C serves as a pasting guide groove for a history recording seal (not shown). Instead of the rectangular groove 222C, for example, a substantially L-shaped, rectangular, or straight-line projection may be provided as a guide for attaching the history recording seal.

  Here, the closing cover part 222 and the base part 224 are each provided with a trace part 232 for leaving a trace of the opening when the cover part 222 and the base part 224 are opened once.

  The trace part 232 includes a cylindrical part 232A provided on the closing cover part 222 side and a screwing part 232B provided on the base part 224 side.

  The cylindrical portion 232A has screws (not shown) accommodated in each of the two cylindrical portions 234, and a surface that is opposite to the surface facing the base portion 224 is relatively thin and breaks with a slight pressure. A member 236 is attached.

  The cover member 236 is formed with a substantially cross notch, and is used as a guide groove for a driver (not shown) as a tool.

  On the other hand, the threaded portion 232B provided in the base portion 224 has two circular groove portions 238 formed therein. A small hole is formed in the bottom surface of the circular groove portion 238.

  Here, when the closing cover portion 222 and the base portion 224 are attached, the two cylindrical portions 234 are set to be coaxial with the two circular groove portions 238, respectively. In this mounted state, first, a screwdriver is applied to one cylindrical part 234, the cover member 236 is pierced, and the screw inside is screwed into the small hole of the circular groove part 238. As a result, the closing cover portion 222 and the base portion 224 are fixed, and at the time of the next opening, either or both of the cylindrical portion 234 and the circular groove portion 238 that have been screwed together are cut off with a nipper or a cutter as a tool. Since a necessity arises, a trace can be reliably left.

  Here, in the present embodiment, the specific area 210A is formed by mounting the closing cover portion 222 and the base portion 224, and the electronic circuit board 218 is accommodated, but separately from the specific area 210A, By attaching the closing cover part 222 and the base part 224, the cavity part 240 is formed. The hollow portion 240 is closed and formed by abutment of a part of the closing cover portion 222 and the base portion 224 in association with the mounting operation. Hereinafter, a part of each of the closing cover portion 222 and the base portion 224 is referred to as a “cover side cavity constituting portion 242” and a “base side cavity constituting portion 244”, and collectively referred to as “a pair of cavity constituting portions 246”. That's it.

  The pair of cavity components 246 are provided along the short side of the circuit board case 210 opposite to the short side where the trace portion 232 is provided.

  Each of the pair of hollow components 246 has a rectangular box shape, and one main surface (surfaces facing each other) is opened. In addition, a through hole 248 is formed in the bottom surface of the cover side cavity component 242 and the opening surface of the through hole 248 is closed by a screw lid 250. The screw lid portion 250 has a structure that can be easily cut with a tool such as a nipper or a cutter, and the through hole 248 is exposed when cut. A driver as a tool is inserted into the through hole 248 when the closing cover portion 222 and the base portion 224 described later are opened.

  Here, when the closing cover portion 222 and the base portion 224 are mounted, the auxiliary member assembly 252 is accommodated in the cavity portion 240.

  When the closing cover portion 222 and the base portion 224 are mounted in a state where the auxiliary member assembly 252 is accommodated in the cavity portion 240, the auxiliary member assembly 252 is covered with the pair of cavity component portions 246, so that the outside is provided from the outside. It becomes a state where it cannot touch.

(Configuration of auxiliary member assembly 252)
As shown in FIG. 7, the auxiliary member assembly 252 includes a pair of rectangular block-shaped auxiliary members 254, 256, a screw 258 for integrating the pair of auxiliary members 254, 256, and a pair of auxiliary members after integration. And a seal seal 260 attached so as to straddle 254, 256.

  Each of the pair of auxiliary members 254 and 256 has a rib 262 except for one long side.

  One auxiliary member 256 is formed with a cylindrical portion 264 on the opposite surface side when abutting, and the other auxiliary member 254 is formed with a circular hole 266 coaxial with the cylindrical portion 264. After the auxiliary members 254 and 256 are abutted with each other, the screws 258 are inserted into the circular holes 266 and screwed into the cylindrical portion 264, so that both are detachably attached. In addition, after the attachment with the screw 258 is completed, the seal seal 260 is pasted across a pair of auxiliary members 254 and 256 so as to be wound around a long side without the rib 262. For this reason, the screw 258 is concealed by the seal seal 260.

  The seal seal 260 is affixed when literally sealing the pair of auxiliary members 254, 256, and has a function of leaving a trace of opening by breaking at the time of opening. The seal seal 260 of the present embodiment has an RFID ([Radio Frequency IDentification] / solid identification by radio wave) function in addition to the main function. That is, although not shown in the figure, an IC chip 268 and an antenna 270 are provided on the back side of the seal seal 260 (IC tag 272). When the IC tag 272 includes a passing tag, a rectifier circuit (not shown) is built in the IC tag 272, and the radio wave received by the antenna 270 from the outside (IC tag reader not shown) is rectified into a direct current. Then, the IC chip 268 is activated by using it as a power source, and the information stored in the IC chip 268 has a function of transmitting a radio wave on a reflected wave of a radio wave partially reflected by the antenna 270.

  In the present embodiment, when transmitted from the IC tag reader, a part of the radio wave is reflected by the antenna 270, and the reflected wave is loaded with the identification information stored in the IC chip 268 and the electronic circuit. When a radio wave is transmitted from the substrate 218, it is possible to determine whether or not there is a fraud such as the seal sticker 260 being replaced by receiving and collating this signal with the IC tag reader.

  As shown in FIG. 8, when the auxiliary member assembly 252 is accommodated in the cavity portion 240, the screw 258 (concealed by the seal seal 260) in the auxiliary member assembly 252 is provided in the cover side cavity constituting portion 242. It is designed to be coaxial with the through hole 248.

  In this state, the auxiliary member 254 is fixed to the cover side cavity constituting portion 242 and the auxiliary member 256 is fixed to the base side cavity constituting portion 244, respectively. As a means for fixing, ultrasonic welding is adopted, and the contact portion between the inner side surface and the pair of auxiliary members 254 and 256 is targeted from the outside of the cover side cavity constituting portion 242 and the base side cavity constituting portion 244. As described above, they are melted and bonded by ultrasonic vibration and pressure (see ultrasonic processing mark 257).

  Note that the fixing means is not limited to ultrasonic welding, but may be fixing means such as pre-applying and assembling an adhesive, or implanting and embedding a needle-like fixing piece with a retaining stopper, but is quick. Considering the appearance after processing and the like, ultrasonic welding is optimal.

  Here, when the cylindrical portion 234 and / or the circular groove portion 238 on the screwed side of the trace portion 232 is cut off to open the closing cover portion 222 and the base portion 224, a pair constituting the auxiliary member assembly 252 is formed. Since each of the auxiliary members 254, 256 is separately fixed to the closing cover portion 222 and the base portion 224, it is also necessary to separate them.

  For this reason, when the screw lid 250 provided in the cover side cavity component 242 is cut off and the driver is inserted into the through hole 248, the driver breaks through the seal seal 260 and reaches the screw 258. By loosening the screw 258, the pair of auxiliary members 254 and 256 are separated, and are brought into close contact with only the sticking force of the seal seal 260.

  For this reason, when the closing cover part 222 and the base part 224 are opened, the sealing seal 260 is inevitably broken.

  The operation of this embodiment will be described below.

  In the game using the pachinko machine 10, when the player operates the grip unit 26, the ball is shot upward by the launching device 165 one by one. The launched game ball PB is driven into the game area 19 of the game board 18 along the outer rail 102 and falls in the game area 19 while changing the direction by hitting the game nail or the windmill. Then, the game ball PB reaching the lower end of the game area 19 without winning a prize is collected into the pachinko machine 10 from the out port 40.

  Further, when the game ball PB wins a start winning opening 20 provided in the game area 19 or passes through the passing gate 22, processing based on the respective game specifications (for example, lottery, etc.) is executed and an LCD display An image display effect on the unit 106, a sound effect using the speaker 60, and the like are executed. Although not shown in the drawing, a predetermined prize ball (payout) is executed when a normal winning opening is won.

(Outline of game specifications)
First, the game control centered on the lottery process in the main control unit 150 will be described.

  When the game ball PB wins the start opening (A) 130 or the start opening (B) 134, it is determined whether or not the start start winning is a valid start winning. The effective start winning means that the reserved balls are not full (for example, four for one starter) and that the game ball PB has won the starter (A) 130 or the starter (B) 134. This will give you the right to draw. In the invalid starting prize, the right to draw is not given, but a predetermined number (about 3 to 5) of prize balls may be paid out.

  If the starting prize is an effective starting prize, a random number is acquired, a pre-stored winning value is read, and both are compared to determine whether the lottery is winning or not.

  If the current gaming state is in jackpot processing or symbol variation pattern production, in order to put the right of the lottery on hold, the number of holdings is incremented by one (+1), and the current gaming state is in jackpot processing If there is no or even during the design variation pattern production, the lottery process is executed by subtracting the hold number by one.

  Based on the winning / losing of the lottery, the symbol variation pattern effect time is set, and a command including the lottery result and the symbol variation pattern time is sent to the sub-control unit 152.

  The sub-control unit 152 notifies the lottery result using the set production time.

  After this notification, if the result of the lottery is a win, a special gaming state (a jackpot process) is executed. In the normal gaming state, the closed attacker 112 is always opened and closed by a predetermined number of rounds (5R, 10R, 15R). The opening time of the attacker 112 is a maximum of 30 seconds. The attacker 112 is closed when a predetermined number (for example, 8 to 10) of game balls are won during the opening, and a predetermined closing time is set. , Go to the next round (open). Thereby, the player can receive a lot of prize balls in a short time.

  Here, the progress of the game is executed by control by cooperation of a plurality of electronic circuit boards 218 provided on the back surface of the game board 18. A plurality of electronic circuit boards 218 and the like are housed and protected in circuit board cases 210, 212, 214, and 216, respectively. In particular, the electronic circuit board 210 corresponding to the main control unit 150 is an important board that performs the winning determination process and the lottery process and manages the progress of the game based on the winning determination result and the lottery result. A mechanism for leaving a trace in the open / close state of 210 is provided.

(Assembly of circuit board case 210)
A procedure for assembling the circuit board case 210 that houses the electronic circuit board 218 corresponding to the main control unit 150 will be described.

  First, the electronic circuit board 218 is applied to the opening of the closing cover portion 222 and fixed with screws 226. In this state, the wiring connector portion 230 passes through the rectangular hole 228, and the surface of the electronic circuit board 218 (the surface on which a plurality of electronic components are attached) faces the space of the closing cover portion 222.

  Next, the pair of auxiliary members 254 and 256 are combined and fixed with screws 258. Thereafter, the seal seal 260 is attached to the inside of the rib 262 so as to straddle the pair of auxiliary members 254 and 256, thereby forming the auxiliary member assembly 252.

  The formed auxiliary member assembly 252 is placed on either the cover side cavity component 242 or the base side cavity component 244. At this time, the head of the screw 258 is made to face the through hole 248 formed in the cover side cavity constituting portion 254.

  With the auxiliary member assembly 252 placed on the cover-side cavity component 242 or the base-side cavity component 244, the closing cover part 222 and the base part 224 are abutted and fitted. In this fitting, a claw portion is formed on one of the closing cover portion 222 or the base portion 224, and the claw portion is elastically deformed in accordance with the abutting operation, and the elastic deformation is released and engaged when it reaches a fixed position. Such a general fitting structure is applicable. Moreover, you may make it fix using stoppers, such as a beth stop and a rivet stop.

  When the closing cover portion 222 and the base portion 224 are assembled, the cavity portion 240 is formed at the same time, and the auxiliary member assembly 252 is accommodated in the cavity portion 240 in a state in which the hand cannot be touched from the outside.

  In the accommodated state of the auxiliary member assembly 252, the cover side cavity component 242 and the auxiliary member 254, and the base side cavity component 244 and the auxiliary member 256 are welded by ultrasonic welding. That is, an ultrasonic welding tool is applied from the outside of the cover side cavity component 242 and the base side cavity component 244, and the cover side cavity component 242, the inner surface of the base side cavity component 244, and the pair of auxiliary members 254, 256. Targeting the contact portion with, it is melted and bonded by ultrasonic vibration and pressure.

  Next, a screwdriver is inserted so as to break through the cover member 236 provided on one cylindrical portion 234 of the trace portion 232, and the screw inside the cylindrical portion 234 is screwed toward the small hole of the circular groove 238. Match. By this screwing, the cylindrical portion 232A and the screwing portion 232B are integrated.

  Thus, the assembly of the circuit board case 210 is completed. In this assembled state, in this embodiment, a radio wave is emitted from the IC tag reader toward the IC tag 272 provided on the seal seal 260, and power is supplied to the IC chip 268 by electromagnetic induction in accordance with the radio wave. Pre-stored identification code information is transmitted from the IC chip 268 activated by this power. The IC tag reader receives the transmitted identification code information and verifies the suitability. That is, if the seal seal 260 is genuine, it matches the identification information stored in the IC tag reader, and if it is illegal, it does not match the identification information stored in the IC tag reader (or is identified by the IC tag reader). Sign information cannot be obtained).

  In this embodiment, since the seal seal 260 is accommodated in the cavity 240 and cannot be touched from the outside, for example, it is peeled off with a solvent, and internal electronic components are replaced or altered. Then, an illegal act such as reattaching the seal sticker 260 becomes impossible.

  Furthermore, each of the pair of auxiliary members 254 and 256 constituting the auxiliary member assembly 252 with the seal seal 260 attached thereto is joined to the cover side cavity component 242 and the base side cavity component 244 by ultrasonic welding. In addition, it can serve as a sealing seal 260 for the closing cover part 222 and the base part 224.

(Removal of the circuit board case 210)
The procedure for separating the closed cover portion 222 and the base portion 224 from the closed circuit board case 210 will be described below.

  First, the cylindrical portion 234 and / or the circular groove 238 on the side where the screw in the trace portion 232 is screwed are cut off by a nipper or a cutter as a tool. That is, the cylindrical portion 234 is separated from the closing cover portion 222, and the circular groove 238 is separated from the base portion 224.

  Next, the screw lid 250 attached to the cover side cavity component 242 is cut off with a nipper or a cutter as a tool. When the screw lid 250 is cut off, the through hole 248 is exposed. A screwdriver as a tool is inserted into the through hole 248. By this insertion operation, the seal seal 260 is first penetrated. That is, a part of the seal seal 260 is broken by the insertion operation of the driver.

  If the driver is further inserted, the screw 258 is reached. When the screwing of the screw 258 is released in this state, the auxiliary member assembly 252 can be effectively separated into the pair of auxiliary members 254 and 256. In this state, when the separation of the closing cover portion 222 and the base portion 224 is started, the auxiliary members 254 and 256 are separated, and the sealing seal 20 is broken with the separation.

  As a result, even if the closing cover portion 222 and the base portion 224 themselves are replaced with unauthorized ones, and there is a situation in which no trace remains in the trace portion 232, the sealing seal 260 cannot be touched by hand from the outside. 240, and is always torn at the time of separation, so that it is possible to avoid an illegal act such as peeling off the seal seal 260 with a solvent.

  Even if the seal seal 260 is replaced with an unauthorized product, the IC chip reader (not shown) performs verification based on comparison of the identification information of the true electronic circuit board 218 by the IC chip reader information notifying function. Thus, it can be determined whether or not the seal seal 260 is appropriate.
