Description

  The present invention relates to a gaming machine such as a pachinko gaming machine, a pachislot gaming machine, or a slot machine.

  Conventionally, a pachinko machine or a pachislot machine controls a jackpot lottery on whether or not to shift to a gaming state advantageous to a player on the main control board, and commands related to the result of the jackpot lottery from the main control board to the sub-control board. The sub-control board transmits data to each rendering means (lamp display means, image display means, and sound generation means) according to the received command.

  Here, in a pachinko machine, a game ball is used as a game medium, and in a pachislot machine, a coin is used as a game medium. A game is executed by inserting game balls or coins, and when a big hit is drawn, a large amount of game media can be paid out. For example, although it depends on the model, approximately 1800 to 2000 game balls can be expected for a big hit with a pachinko machine, and about 350 to 400 payouts can be expected for a big hit with a pachislot machine. The player is given a privilege that the game can be continued for a long time by winning the jackpot or can be exchanged for a prize in exchange for a game medium.

However, there is a person who tries to illegally remodel the control board for the purpose of obtaining the above-mentioned privilege illegally. Conventionally, a case body that accommodates the control board 3 and a cover body that is attached to the case body are provided, and the case body and the cover body cannot be separated by a coupling means. In order to achieve this, a technique has been proposed in which the joint portion must be destroyed and the trace clearly remains (Patent Document 1).
JP 2006-061705 A

  However, in the prior art, a special jig for separating the case body and the cover body has been developed, and when the case body and the cover body are separated so as not to stand out by a skilled technician, There remains a risk that the control board may be tampered with.

  In addition, since it is highly likely that a person who performs such an illegal act is a person who is familiar with pachinko or pachislot machines, sufficient security measures can be taken only by devising the structure of the case body and cover of the control board. I can't say I'm doing it. For this reason, even if the cover is opened, it is necessary to improve the security of the electronic component itself so that the electronic component mounted on the control board is not illegally modified or analyzed.

  By the way, in order to perform such an illegal act, the main CPU of the main control circuit or the main ROM storing the random number table for the big hit lottery is likely to be a target and the terminal is exposed to the outside. If there is, there is a possibility that CPU analysis and ROM analysis are easily performed. In addition, since the design is performed using a general-purpose integrated circuit and the product is a general-purpose product, there is a risk of unauthorized modification or duplication by CPU analysis or ROM analysis. For this reason, it is necessary to improve the security of the main electronic components in the main control circuit.

  Furthermore, in recent years, in addition to the privilege of providing game media, a model equipped with a privilege that provides a premium image that cannot be seen in normal games and displays the premium image only when a predetermined condition is satisfied. Has also appeared. And, unlike the game for the purpose of giving away prizes, the number of players who play a game to see a premium image is increasing. Further, there is no guarantee that fraud such as unauthorized modification of the sub-control board and alteration of the image data for production will not be performed in the future. Therefore, there is a possibility that the security of the main circuit element itself in the sub control board becomes a problem.

  As shown in FIG. 8B, a plurality of device electrodes 413 are arranged in parallel on the back surface of the microprocessor 411, and metal bumps (for example, Au bumps) 414 are formed on the device electrodes 413. On the other hand, solder 417 is formed by plating on a portion of the printed circuit board 415 facing the metal bump (for example, Au bump) 414. Then, by placing the microprocessor 411 on the printed board 415 and melting the solder 417, the periphery of the metal bump 414 is covered with the solder 417. Then, the microprocessor 411 is fixed on the element electrode 413 by cooling, and then the resin 418 is injected to mount the microprocessor 411 on the element electrode 413.

  With this configuration, the microprocessor 411 that is a bare chip component is directly fixed to the printed board by the solder 417 and the resin 418. Therefore, if the microprocessor 411 is forcibly removed from the board, the microprocessor 411 itself Will be damaged, making analysis impossible. In addition, when the microprocessor 411 is to be removed cleanly, an operation for removing the resin 418 and an operation for melting the solder 417 are required, which is an extremely difficult operation.

The method for mounting the ROM chip 431 on the printed board is the same as the mounting method for the main control board 410 described above. In addition, a plurality of substrate electrodes that are directly or indirectly connected to electronic components on the printed circuit board are formed on one side of both sides extending in the longitudinal direction of the printed circuit board. Then, by inserting this side portion into a connector for the cartridge ROM 421 provided on the sub-control board 420, the internal board 430 of the cartridge ROM 421 and the sub-control board 420 are electrically connected. As described above, the sub-control board 420 mounts a plurality of types of electronic components, receives a lottery result command transmitted from the main control board (for example, the main control board 410), and performs various effects based on the command. It is an example of the sub control board which comprises the production | presentation control circuit which controls execution of this. Further, the ROM chip 431 is an example of an electronic component that is a bare chip component and is an electronic component that functions as an effect data storage circuit that stores data for performing various effects. The ROM chip 431 is an example of a bare chip component that is flip-chip mounted on a sub control board (for example, a printed board 432 in the sub control board 420).

With this configuration, since the memory component that is a bare chip component is directly fixed to the printed circuit board by solder and resin, if the memory component is forcibly removed from the substrate, the memory component itself is damaged. It becomes impossible to perform analysis. Further, when it is attempted to remove the memory parts cleanly, an operation for removing the resin and an operation for melting the solder are required, which is a very difficult operation.

  The gaming state of the embodiment basically includes a general gaming state, an RB gaming state, and a challenge bonus gaming state (hereinafter abbreviated as “CB gaming state”). The gaming state can be basically distinguished by the type of the internal lottery table used for determining the internal winning combination and the stop control mode of the reels (the so-called “sliding frame number” maximum number, etc.). Specifically, the gaming state can be distinguished by the types of roles that may be won internally, the probability of winning internally, the maximum number of sliding symbols, and the like.

  FIG. 16 is based on a main control circuit 1071 that controls a game processing operation in the gaming machine 1001, a peripheral device (actuator) that is electrically connected to the main control circuit 1071, and a control command transmitted from the main control circuit 1071. A circuit configuration including a liquid crystal display device 1131, speakers 1009L and 1009R, LEDs 1100a, and a sub-control circuit 1072 for controlling lamps 1100b is shown.

  The main control circuit 1071 includes a microcomputer 1030 disposed on a circuit board as a main component, and is added to a circuit for random number sampling. The microcomputer 1030 includes a CPU 1031 that performs a control operation according to a preset program (FIGS. 24 to 31 described later), and a ROM 1032 and a RAM 1033 that are storage means. The main control circuit 1071 is formed on the printed circuit board by mounting electronic components constituting these circuits on the printed circuit board. Further, the microcomputer 1030 is made of a bare chip component, and is flip-chip mounted on a printed board as shown in FIG. As a result, if the microcomputer 1030 is forcibly removed from the substrate, the microcomputer 1030 is damaged, so that the removal becomes difficult, and the CPU analysis and the ROM analysis become extremely difficult. In this manner, the main control circuit 1071 mounts a plurality of types of electronic components, and provides the player with an execution control circuit (for example, the CPU 1031) that controls the execution of the game using the game medium and a predetermined number of game media. It is an example of the main control board which comprises the lottery control circuit (for example, CPU1031) which determines whether it is by lottery. The microcomputer 1030 is a bare chip component that functions as an execution control circuit and a lottery control circuit (for example, the CPU 1031), and is flip-chip mounted on a main control board (for example, a printed circuit board on which the main control circuit 1071 is formed). This is an example of an electronic component.

  Connected to the CPU 1031 are a clock pulse generation circuit 1034 and a frequency divider 1035 for generating a reference clock pulse, and a random number generator 1036 and a sampling circuit 1037 for generating a random number to be sampled. As a means for random number sampling, random number sampling may be executed in the microcomputer 1030, that is, on the operation program of the CPU 1031. In that case, the random number generator 1036 and the sampling circuit 1037 can be omitted, or can be left as a backup for the random number sampling operation.

  In the ROM 1032 of the microcomputer 1030, the reels are stopped according to the operation of a probability lottery table, a winning combination determination table for stop, and a stop button used for determination of random number sampling performed every time the start lever 1006 is operated (start operation). A stop table group for determining the mode is stored. In addition, various control commands (commands) to be transmitted to the sub control circuit 1072 are stored. The sub control circuit 1072 does not input commands, information, and the like to the main control circuit 1071, and communication is performed in one direction from the main control circuit 1071 to the sub control circuit 1072. Various information is stored in the RAM 1033. For example, information such as an internal winning combination, a carryover combination, and a current game state, which will be described later, is stored. As described above, the microcomputer 1030 is a bare chip part including a storage part (ROM 1032) storing a random number table used for random number lottery, and is flipped to a main control board (for example, a printed board on which the main control circuit 1071 is formed). It is an example of the electronic component mounted on the chip.

  In the circuit of FIG. 16, the main actuators whose operation is controlled by a control signal from the microcomputer 1030 are BET lamps (1-BET lamp 1017a, 2-BET lamp 1017b, maximum BET lamp 1017c), and bonus game information. A display unit such as a display unit 1016, a payout display unit 1018, a credit display unit 1019, and a hopper (including a drive unit for payout) 1040 that stores medals and pays out a predetermined number of medals according to a command from the hopper drive circuit 1041. And stepping motors 1049L, 1049C, and 1049R for rotating the reels 1003L, 1003C, and 1003R.

  Further, a motor driving circuit 1039 for driving and controlling the stepping motors 1049L, 1049C and 1049R, a hopper driving circuit 1041 for driving and controlling the hopper 1040, a lamp for driving and controlling the 1-BET lamp 1017a, the 2-BET lamp 1017b and the maximum BET lamp 1017c. A driving circuit 1045 and a display unit driving circuit 1048 for driving and controlling display units such as a bonus game information display unit 1016, a payout display unit 1018, and a credit display unit 1019 are connected to an output unit of the CPU 1031. Each of these drive circuits receives a control signal such as a drive command output from the CPU 1031 and controls the operation of each actuator.

  The main input signal generating means for generating an input signal necessary for the microcomputer 1030 to generate a control command includes a start switch 1006S, stop switches 1007LS, 1007CS, 1007RS, 1-BET switches 1011, 2-BET. There are a switch 1012, a maximum BET switch 1013, a C / P switch 1014, a medal sensor 1010S, a reel position detection circuit 1050, and a payout completion signal circuit 1051.

  The start switch 1006S detects an operation of the start lever 1006 and outputs a game start command signal (signal for instructing the start of the game). The medal sensor 1010S detects a medal inserted into the medal slot 1010. The stop switches 1007LS, 1007CS, and 1007RS generate stop command signals (signals that command the stop of symbol variation) in response to operations of the corresponding stop buttons 1007L, 1007C, and 1007R. The reel position detection circuit 1050 receives the pulse signal from the reel rotation sensor and supplies a signal for detecting the position of each reel 1003L, 1003C, 1003R to the CPU 1031. The payout completion signal circuit 1051 generates a signal for detecting completion of the medal payout when the count value of the medal detection unit 1040S (the number of medals paid out from the hopper 1040) reaches the designated number data.

  In the circuit of FIG. 16, a random number generator 1036 generates a random number belonging to a certain numerical range, and a sampling circuit 1037 samples one random number at an appropriate timing after the start lever 1006 is operated. By using the random numbers sampled in this way, an internal winning combination or the like is determined based on, for example, a probability lottery table stored in the ROM 1032. The internal winning combination (internal winning combination data) indirectly associates the corresponding symbol combination with the profit given to the player through the stop control mode corresponding to the internal winning combination or the display combination. It can be said that.

  After the rotation of the reels 1003L, 1003C, and 1003R is started, the number of drive pulses supplied to each of the stepping motors 1049L, 1049C, and 1049R is counted, and the counted value is written in a predetermined area of the RAM 1033. From the reels 1003L, 1003C, and 1003R, reset pulses are obtained every rotation, and these pulses are input to the CPU 1031 via the reel position detection circuit 1050. The count value of the drive pulse counted in the RAM 1033 is cleared to “0” by the reset pulse thus obtained. As a result, the RAM 1033 stores count values corresponding to the rotation positions within one rotation range for each of the reels 1003L, 1003C, and 1003R.

  A symbol table (not shown) is stored in the ROM 1032 in order to associate the rotational positions of the reels 1003L, 1003C, and 1003R with the symbols drawn on the outer peripheral surface of the reel. In this symbol table, a code number that is sequentially given for each fixed rotation pitch of each reel 1003L, 1003C, and 1003R with reference to the rotational position where the reset pulse is generated as described above is provided for each code number. A symbol code indicating the displayed symbol is associated with the symbol.

  Furthermore, a symbol combination table (not shown) is stored in the ROM 1032. In this symbol combination table, a symbol combination for winning a combination (winning, etc.), a medal payout number for winning, and a winning determination code (establishment determining code) representing the winning (establishment) are associated with each other. The above symbol combination table is used when the left reel 1003L, the center reel 1003C, and the right reel 1003R are controlled to stop and when winning confirmation (confirmation of display combination) after all the reels 1003L, 1003C, and 1003R are stopped. Referenced. The display combination (display combination data) is basically a combination (established combination) corresponding to the symbol combination arranged along the effective line. The player is given a profit corresponding to the display combination.

  When the internal winning combination or the stop winning combination is determined by the lottery process (probability lottery process or the like) based on the random sampling, the CPU 1031 stops the stop switch 1007LS at the timing when the player operates the stop buttons 1007L, 1007C, and 1007R. , 1007CS, 1007RS, and a stop control signal for the reels 1003L, 1003C, 1003R based on the operation signal sent from the control signal and the determined stop table, are sent to the motor drive circuit 1039.

  If it becomes a stop mode (that is, a winning mode) indicating the winning of the winning combination, the CPU 1031 supplies a payout command signal to the hopper driving circuit 1041 and pays out a predetermined number of medals from the hopper 1040. At this time, the medal detection unit 1040S counts the number of medals to be paid out from the hopper 1040, and when the count value reaches a designated number, a medal payout completion signal is input to the CPU 1031. As a result, the CPU 1031 stops driving the hopper 1040 via the hopper drive circuit 1041 and ends the medal payout process. As described above, the CPU 1031 is an example of a lottery control circuit that performs control for determining whether or not to provide a predetermined number of game media (for example, coins) to the player by random number lottery. Each of the reels 1003L, 1003C, and 1003R is an example of a spinning device that displays a combination of a plurality of symbols by arranging a plurality of reel bodies having a plurality of symbols in parallel and rotating and stopping each reel body. Further, the CPU 1031 operates a spinning device (for example, reels 1003L, 1003C, and 1003R, stop buttons 1007L, 1007C, and 1007R) that can be rotated in exchange for coins that are game media, by operating means (for example, a start lever) by the player. 1006) is an example of an execution control circuit that performs control to rotate and stop based on the operation of 1006).
