Description

  The present invention relates to a swivel type gaming machine in which a predetermined amount of game media is paid out according to a combination of symbols stopped and displayed in a plurality of areas.

  2. Description of the Related Art A spinning-type gaming machine is known in which a plurality of spinning cylinders on which a plurality of types of symbols are drawn are rotated, and a predetermined number of game medals are paid out by combining the obtained symbols. In this revolving game machine, a game is performed in the following manner. First, when a predetermined number of game medals are inserted and medals are bet and a start lever is operated, a plurality of spinning cylinders start to rotate all at once. Next, the rotation of the rotating cylinder is stopped by pressing a stop button provided on each rotating cylinder. Since a plurality of kinds of symbols are drawn on the surface of the rotating drum, any combination of symbols can be obtained by stopping each rotating drum. When the combination of symbols obtained in this way is a symbol combination that establishes a predetermined game combination, a predetermined number of game medals are paid out according to the established game combination.

  In such a spinning-type game machine, it seems at first glance whether or not a symbol combination that can establish a game character can be obtained is determined by the timing of pressing the stop button of each spinning cylinder. A lottery is performed at the time when is operated, and it is determined which game combination is to be established. Therefore, if any game player is not won by lottery, the player cannot be stopped by pressing the stop button at any timing, and conversely, if any game player is won Even if the timing of pressing the stop button is slightly deviated, each cylinder is stopped so that a symbol combination corresponding to the game combination can be obtained. As described above, the lottery of game players performed when the start lever is operated is generally called “internal lottery”.

  This internal lottery is performed by generating a random number one after another, and the value of the random number circulates at a constant cycle. For this reason, it is possible to always obtain the same internal lottery result by operating the start lever in synchronization with the cycle in which the random number makes a round, and this is used to illegally pay out game medals (so-called goto Act) may be performed. Various techniques have been proposed in order to prevent such an action (Patent Document 1, Patent Document 2, etc.).

  For example, in Patent Document 1, a technique is provided in which a separate member is provided at the tip of the start lever so that a random number is acquired at a timing delayed by the amount of play when the start lever is operated. Proposed. According to the proposed technique, even if the start lever is operated at a constant cycle, the random number acquisition timing is delayed by the amount of play, so the internal lottery result does not become the same. Can be prevented.

  Further, in Patent Document 2, a separate member having a plurality of slits is provided at the tip of the start lever, and a plurality of random numbers are obtained each time the start lever is operated once. A technique for selecting a random number has been proposed. According to the proposed technique, since the internal lottery is performed using a random number selected from a plurality of random numbers, even if the start lever is operated at a constant cycle, the obtained internal lottery result is the same. Therefore, it is possible to prevent the above-mentioned gore action.

  However, according to the proposed technique, it is necessary to provide a separate member in a manner movable with respect to the start lever. Therefore, there is a problem that a failure is easily caused by an increase in the movable part. In particular, since the start lever is frequently operated during a game, a high-reliability is required for a revolving game machine. Therefore, if the reliability of the operation is impaired even a little, it is a big problem. In addition, since another member is provided, there is a problem that a large remodeling including a start lever is required in order to be mounted on an existing rotary type gaming machine.

  The present invention has been made in order to solve the above-described problems in the prior art, and provides a swivel type gaming machine capable of easily preventing a goto action without impairing the reliability of operation. With the goal.

In order to solve at least a part of the above-described problems, the rotating game machine of the present invention employs the following configuration. That is,
After the symbols are variably displayed in a plurality of areas, if the combination of symbols that are stopped and displayed is a symbol combination that corresponds to a game combination that has been determined in advance through a lottery, a predetermined amount is selected according to the game combination. In a spinning machine where game media is paid out,
Random number generating means for periodically generating a plurality of types of random numbers used in the lottery;
A variation start member operated to start the variation display of the symbols in the plurality of regions;
A detection sensor that detects that the fluctuation start member has been operated and outputs a detection signal;
Operating power supply means for supplying operating power to the detection sensor;
Lottery means for lottery of the game actors by acquiring the random number according to the timing at which the detection sensor outputs the detection signal ;
A power supply circuit that generates power for operating the rotary gaming machine by rectifying an AC voltage supplied from outside ;
The operating power supply means receives the power in a pulsating state after rectification from the power supply circuit, transforms it to a predetermined voltage, and then supplies the operating power to the detection sensor, so that the detection sensor can operate the operating power. The power is supplied to the detection sensor while fluctuating between normal power and inoperable power.

  In such a swivel type gaming machine of the present invention, when the variation start member is operated, the variation display of symbols is started in a plurality of areas, and a detection signal is output from the detection sensor. When the lottery means receives the detection signal from the detection sensor, the lottery means obtains a random number generated by the random number generating means and draws a game player. Here, since the random number generation means periodically generates a plurality of types of random numbers, if the detection signal can be output in a cycle in which the random numbers are updated, the random number is always acquired and eventually the same game It is possible to win a role. In fact, in a general spinning machine, by operating the change start member in synchronization with the random number update cycle using a special device, the detection signal is output at the cycle in which the random number is updated. There is a case where a fraudulent act is performed in which a specific game player is elected and a large amount of game media is paid out.

  On the other hand, in the spinning cylinder type gaming machine of the present invention, the operating power supplied to the detection sensor is supplied while being changed between power that can be operated by the detection sensor and power that cannot be operated. Even if is operated, the detection signal is not always output immediately. In other words, when the fluctuation start member is operated, if the power that can operate the detection sensor happens to be output immediately, the detection signal is output immediately, but if the power that can be operated is not supplied, the fluctuation start member is operated. Even if this is done, no detection signal is output. Then, a detection signal is output when the power supplied to the detection sensor is switched to operable power, or when the fluctuation start member is operated again and operable power is supplied to the detection sensor. become. In this way, since the time from when the fluctuation start member is operated until the detection signal is output fluctuates, even if the fluctuation start member is operated at a cycle in which the random number is updated, the acquired random number is the same value. Therefore, it is impossible to always win a specific game player. For this reason, it is possible to effectively prevent an illegal act of paying out a large amount of game media by operating the variation starting member using a special instrument.

  Moreover, according to the method described above, fraudulent acts can be prevented simply by changing the power supplied to the detection sensor. For this reason, only the electric system is different from that of a normal swivel-type game machine, and the number of movable parts is not increased, so that reliability is not lowered at all. Furthermore, even when an existing swivel game machine is refurbished to take measures against fraud, it is possible to refurbish very easily because only the electrical system needs to be changed.

In addition , in the above-described spinning-type game machine, electric power for operation is generated by rectifying an AC voltage supplied from the outside , and a voltage in a pulsating state after rectification is predetermined. Operating power is supplied to the detection sensor by transforming the voltage into voltage and supplying the obtained power to the detection sensor . As the AC voltage rectification method, there is a method called half-wave rectification in which the negative voltage portion is cut, or full-wave rectification in which the negative voltage portion is rectified to a positive voltage by changing the sign without changing the waveform. Various methods such as a so-called method exist, but any rectification method can be used as long as the voltage after rectification is in a pulsating state.

It is possible to obtain very easily because of the widespread if AC voltage, by generating a power for operating the reel-type gaming machine from the AC voltage, to easily operate the reel-type gaming machine be able to. In addition, after rectifying the ac voltage in order to generate operating power for the reel-type gaming machine, it is sufficient to transform the voltage in the pulsating state, detection sensors inoperable and operable power It is possible to easily generate electric power that varies with electric power .

A-2. Electrical configuration:
FIG. 3 is an explanatory diagram showing an electrical configuration of the gaming machine 1 according to the present embodiment. As shown in FIG. 3, the gaming machine 1 includes a main control board 200 and a sub-control board 220, a door board 240, a rotating board 260, a power board 280, and the like that are connected so as to be able to exchange data. ing.

  The main control board 200 is a board that manages the progress and production of the entire game performed in the gaming machine 1. The main control board 200 is mounted with a CPU, ROM, RAM, etc. connected to each other via a bus so that data can be exchanged with each other. The start lever 36 is operated from the door board 240 mounted on the front door 2. These signals are output to the sub-control board 220, the door board 240, the rotor board 260, and the like while executing a game control process to be described later. Controls the operation of various substrates.

  Similarly to the main control board 200 described above, the sub control board 220 is configured by connecting a CPU, a ROM, a RAM, and the like so as to exchange data with each other via a bus. In addition, various lamps 12, various speakers 14 and 114, the effect display device 10, and a rotating backlight 20 </ b> L are connected to the sub control board 220. Here, the spinning cylinder backlight 20L is a light that is provided inside each spinning cylinder 20a, 20b, 20c and illuminates a pattern drawn on the surface of the spinning cylinder from the back side. The sub control board 220 analyzes the control command received from the main control board 200, and outputs drive signals to the various lamps 12, the various speakers 14, 114, the effect display device 10, and the rotary backlight 20L, respectively. Various performances using these are performed.

  On the door board 240, the above-described medal selector 106, various insertion buttons 32 and 34 for inserting the stored game medals, the start lever 36 for starting the rotation of the rotating drum, the rotating rotating drum Rotation stop buttons 38a, 38b, 38c for stopping the game, a settlement button 40 for paying out the stored game medals or the inserted game medals and ending the game, and various display panels for displaying the game status 22 etc. are connected. The door board 240 is connected to the main control board 200 described above so as to exchange data. For this reason, when the start lever 36 provided on the front door 2, the rotating cylinder stop buttons 38a, 38b, 38c, the various input buttons 32, 34, the adjustment button 40, etc. are operated, the signal is transmitted via the door substrate 240. Can be supplied to the main control board 200. The output of the medal sensor provided in the medal selector 106 is also supplied to the main control board 200 via the door board 240.

  In the gaming machine 1 of the present embodiment, a special method is used in order to avoid an act of illegally paying out a game medal by operating the start lever 36 at a constant period. It is detected using. This point will be described in detail later, including the detailed structure of the start lever 36.

  On the rotating board 260, the rotating motors 24a, 24b, 24c for rotating the three rotating cylinders 20a, 20b, 20c, respectively, and the rotating sensors 26a, 26b for detecting the rotational positions of the respective rotating cylinders. , 26c. The rotating substrate 260 detects the rotational position of each of the rotating cylinders 20a, 20b, and 20c by the rotating sensors 26a, 26b, and 26c, and drives the rotating motors 24a, 24b, and 24c, thereby rotating the respective rotating cylinders 20a. , 20b, 20c can be stopped at a desired rotational position. In the gaming machine 1 of this embodiment, so-called stepping motors are used for the spinning motors 24a, 24b, and 24c.

  The medal payout device 118 is connected to the main control board 200 via a relay board (not shown), and performs an operation of paying out a predetermined number of game medals based on a control signal from the main control board 200.

  These various control boards and the power consumed by the boards are supplied from the power supply board 280. An AC voltage of 100 V is supplied to the power supply board 280, and this electric power is converted into a DC voltage of a specified voltage and then supplied to each control board and board. In FIG. 3, a state in which power is supplied from the power supply board 280 is represented by a dashed arrow.

B. Overview of the game:
In the following, the contents of the control performed in order to advance the game in the rotary type gaming machine 1 having the above-described configuration will be described, but as an preparation, an outline of the game performed in the rotary type gaming machine will be described. Keep it.

  In starting the game, a game medal is inserted from the game medal slot 30 and a medal bet is placed. The number of game medals to bet is usually fixed to one or three. If game medals are stored in advance as credits, it is possible to bet 1 or 3 game medals by pressing the 1-sheet insertion button 32 or the 3-sheet insertion button 34, respectively. is there.

  When a game medal is bet and the start lever 36 is operated, the three spinning cylinders 20a, 20b, and 20c start rotating all at once. Since a plurality of symbols are drawn on each rotator, these symbols are displayed in a variable manner when the rotator rotates. Further, as described above with reference to FIG. 1, on the front side of the front door 2, three turning stop buttons 38 a, 38 b, 38 c are provided corresponding to the respective turning cylinders. When the rotating cylinder stop buttons 38a, 38b, 38c are pressed while the rotating cylinders 20a, 20b, 20c are rotating, the rotating cylinders corresponding to the pressed buttons stop rotating, and the symbols that are displayed in a variable manner are displayed. Stopped display with any of the symbols. When the rotation of the three spinning cylinders 20a, 20b, and 20c is stopped in this way, any symbol is stopped and displayed on each of the spinning cylinders, and some symbol combinations are obtained. When the symbol combination obtained in this way is a combination that establishes a so-called “small role”, a game medal corresponding to the established game role is paid out. When the number of game medals bet is 3, it is possible to receive a payout of 3 times of game medals when only one bet is placed.

  Also, for the following reasons, the more the number of game medals to bet, the easier it is to establish a game combination. First, the display window 20 provided on the front door 2 is provided with a size capable of displaying three symbols drawn on the rotating drum. Accordingly, when the rotation of each of the spinning cylinders 20a, 20b, and 20c is stopped, three symbols are stopped and displayed on each of the spinning cylinders, so that three sets of symbols of the upper, middle, and lower stages are displayed in the horizontal direction. A combination is obtained, and two symbol combinations are obtained in the diagonal direction. The direction in which the symbol combination is obtained in this way is called “line”, and as a result, there are 5 lines in total, 3 lines in the horizontal direction and 2 lines in the diagonal direction. Here, when there are three game medals bet, all these five lines are valid, and it is only necessary to align the symbol combinations of the game actors on any line, but only one game medal was bet. In such a case, the effective lines are limited, and even if the symbol combinations of game actors are arranged on other lines, the game actors cannot be established. That is, it is easier to establish a game combination when the number of game medals to bet is larger.

  In addition to the “small role”, the game character is also provided with a so-called “bonus role”. When a symbol combination that establishes the bonus role is obtained, the game state is given to the player. Switch to an advantageous state. The bonus combination is provided with a so-called “regular bonus combination (hereinafter referred to as RB combination)” and “big bonus combination (hereinafter referred to as BB combination)”. In the case of the RB combination, a game combination is established. “RB game” is performed in which the types of symbol combinations increase and the probability that these game combinations will be established becomes high. In the case of the BB combination, a game state that is more advantageous for the player than the RB combination, that is, the “RB game” can be performed a plurality of times until a predetermined number (for example, 465) of game medals are paid out. Switch to gaming state. As a result, when the BB combination is established, the player can acquire a large amount of game medals.

  As described above, in the spinning cylinder type gaming machine 1, after rotating the spinning cylinders 20a, 20b, and 20c by betting game medals and operating the start lever 36, the spinning cylinder stop button 38a is operated. , 38b, 38c are pressed to stop the rotation of the rotating drum. Depending on the symbol combination obtained at that time, a game medal is paid out or the game progresses while switching to an advantageous game state. Since the most amount of game medals can be obtained when the BB combination is established, the player continues the game while always wishing to establish the BB combination.

  The progress of such a game is controlled by the main control board 200. Below, the processing content which the main control board 200 is performing in order to control progress of a game is demonstrated.

C. Overview of control:
FIG. 4 is a flowchart showing a game control process performed by the main control board 200 for controlling the progress of the game in the gaming machine 1 of the present embodiment. This game control process is executed after the gaming machine 1 is turned on and after initialization processes such as a thumb check of the ROM mounted on the main control board 200 and the sub control board 220 and a clearing of the RAM are performed. Process.

  As shown in FIG. 4, in the game control process, first, it is determined whether or not a game medal is bet (step 10; hereinafter, “step” is abbreviated as “S”). That is, it is determined whether or not a game medal is inserted from the game medal slot 30 or whether or not the one-sheet insertion button 32 or the three-sheet insertion button 34 is operated (S10). As described above, a game medal inserted from the game medal slot 30 is detected by a medal sensor (not shown) provided in the medal selector 106 when passing through the medal selector 106. Further, a contact switch is built in each of the one-sheet input button 32 and the three-sheet input button 34, and when these input buttons are operated, the contact switch detects the operation. Since the detection signals from the medal sensors and contact switches are supplied to the main control board 200 via the door board 240, the main control board 200 determines whether a game medal has been bet based on these detection signals. It can be determined whether or not. If a special game combination called “replay combination” is established, the player is automatically bet even if he / she does not bet a game medal, so even if “replay combination” is established, It is determined that a medal is bet (S10: yes).

  If it is determined in S10 that no game medal is bet (S10: no), the determination process (S10) is repeated to wait until a game medal is bet. On the other hand, if it is determined that a game medal has been bet (S10: yes), it is determined whether or not the start lever 36 has been operated (S20). As will be described in detail later, the start lever 36 incorporates a detection sensor, which will be described later, and when the start lever 36 is operated, its movement can be detected. The main control board 200 can determine whether or not the start lever 36 has been operated based on the output of the detection sensor. If it is determined that the start lever 36 has not been operated even though the game medal has been bet (S20: no), the standby state is maintained while repeating this determination until the start lever 36 is operated. Become. On the other hand, if it is confirmed that the start lever 36 has been operated (S20: yes), the following series of processes is performed to advance the game.

  When the start lever 36 is operated, an internal lottery process is immediately performed (S30). In this process, one random number for internal lottery is acquired at the timing when the start lever 36 is operated, and a process of internally drawing game players according to the acquired random number is performed. In order to establish a game combination as described above, the three spinning cylinders 20a, 20b, and 20c must be stopped so that a predetermined symbol combination corresponding to the game combination is obtained. Inside the machine 1, there is a lottery to determine which game combination is to be established. If this lottery is not won, the game combination can be made no matter what timing the rotation stop buttons 38a, 38b, 38c are pressed. The spinning cylinders 20a, 20b, and 20c cannot be stopped by the symbol combination. Therefore, when the start lever 36 is operated, first, an internal lottery is performed to determine which game combination is established or which game combination is not established.

  As will be described in detail later, in the internal lottery, random numbers for internal lottery are periodically updated, random numbers are acquired according to the timing at which the start lever 36 is operated, and based on the obtained random numbers, The decision is made. For this reason, when the start lever 36 is pushed in synchronization with the cycle in which the internal lottery random number is updated, the same random number is always acquired, so that the same game combination can always be won. As a matter of fact, a lot of game medals are paid out by operating the start lever 36 in synchronization with the internal lottery random number update cycle using a special device and always winning one of the gamers by internal lottery. Cheating may occur. In view of these points, in the gaming machine 1 of the present embodiment, when the start lever 36 is operated, it is ensured that the above-described fraud is performed by acquiring a random number for internal lottery by a method described later. It is possible to prevent.

The main control board 200 starts the rotation rotation starting process following the internal lottery process (S40). In the rotation rotation starting process, it is determined whether or not a predetermined condition is satisfied, and when the condition is satisfied, the three rotation cylinders 20a, 20b, and 20c are simultaneously rotated. In the rotation rotation start processing of the present embodiment, a predetermined time (for example, 4.1 seconds) has elapsed since the start lever 36 was operated and rotation of the rotation cylinders 20a, 20b, and 20c was started last time. In this case, the rotation of the spinning cylinder is started, and a process of outputting a drive signal to the spinning cylinder motors 24a, 24b, and 24c provided in the respective spinning cylinders 20a, 20b, and 20c is performed.
Yes.

  After the three spinning cylinders 20a, 20b, and 20c are thus rotated all at once, the main control board 200 performs a process for stopping the rotation of the spinning cylinder (rotating cylinder rotation stopping process) (S50). In this process, the rotation of the rotating cylinders 20a, 20b, 20c is started, and when the rotating cylinder stop buttons 38a, 38b, 38c are pressed within a predetermined time (for example, 30 seconds) after the rotation speed becomes constant, After determining the symbol to be stopped and displayed by the rotating cylinder, the rotational speed of the rotating cylinder is reduced, and the rotating cylinder is controlled to stop at the determined symbol position. Also, when determining the symbols to be stopped, the result of the internal lottery performed earlier is referred to, and if no game combination is won, avoid the combination of symbols in which the game combination is established In this way, the stop pattern of each cylinder is determined.

  Some supplementary explanation will be given on this point. First, when the rotating cylinder stop buttons 38a, 38b, and 38c are pressed, a temporary stop pattern is determined for each rotating cylinder based on the rotation position of the rotating cylinder at the timing when the buttons are pressed. Next, referring to the results of the internal lottery, if any game combination is not won, whether or not the tentatively determined stop symbol is a combination of symbols that establishes any game combination Determine whether. If there is no symbol combination that establishes any game combination, the tentatively determined stop symbol is adopted as it is and determined as the final stop symbol. If the temporary stop symbol is a symbol that establishes one of the game actors, the stop symbol is changed so that the game actor is not established, and the changed symbol is determined as the final stop symbol .

  On the other hand, if any game combination is won by internal lottery, it is determined whether or not the winning game combination is established based on the temporarily determined stop symbol. If the winning game combination can be established, the temporary stop symbol is determined as the final stop symbol as it is. On the other hand, if the winning game combination cannot be established depending on the temporarily determined stop symbol, the following processing is performed. First, it is determined whether or not the winning game combination can be established by slightly shifting the temporarily determined stop symbol. The number of frames that can be shifted is generally set within 4 frames. If the winning game combination can be established by correcting the provisional stop symbol within the range of the predetermined number of frames, the stop symbol is corrected so that the game combination is established, and the final stop Determine as a symbol. However, if it is not possible to make a symbol combination that establishes the winning game player by simply shifting within the range of the predetermined number of frames, the temporary stop symbol is not modified and adopted as it is. As a stop symbol.

  In the rotation rotation stop processing (S50) shown in FIG. 4, the stop symbols at the respective rotation cylinders 20a, 20b, and 20c are determined as described above, and the respective rotation cylinders 20a, 20b, and 20c are determined at the determined positions. Process to stop. In the above, the case where the rotation stop buttons 38a, 38b, and 38c are pressed within a predetermined time (for example, 30 seconds) after the rotation speed of the rotation reaches a constant speed has been described. Even if the spinning cylinder stop buttons 38a, 38b, and 38c are not pressed, it is assumed that the button has been pressed when the time has elapsed, and the above-described processing is performed.

  As described above, when the three cylinders 20a, 20b, and 20c are stopped, the main control board 200 determines whether or not a winning is achieved (S60). Here, “winning” means that after winning a game combination by internal lottery, the symbol combination that establishes the game combination is displayed in a stopped state on the active line. As described in the rotation rotation stop processing (S50), even if a game combination is won in the internal lottery, depending on the timing of pressing the rotation stop buttons 38a, 38b, 38c, the symbol combination corresponding to the game combination is determined. It is not necessarily obtained. Therefore, after stopping the rotation of the spinning cylinder, the main control board 200 determines whether or not the winning combination of the game player won in the internal lottery has been established.

  As a reference, FIG. 5 illustrates various game combinations set in the gaming machine 1 of the present embodiment and symbol combinations for establishing these game combinations. FIG. 5 also shows the number of game medals to be paid out when winning each game combination. As shown in the drawing, in the gaming machine 1 of the present embodiment, “BB role”, “RB role”, “tin small role”, “plum small role”, “cherry small role”, “replay role” ”Etc. are set. In addition, the symbol combination corresponding to “BB role” is set to the symbol combination “7-7-7” or “volcano-volcano-volcano”. Similarly, the symbol combination corresponding to “RB role” is set to the combination of “bar-bar-bar”, and the combination of “tin-tin-tin” A combination of “Plum-Plum-Plum” is set for “Plum Minor”. Also, the “cherry small part” is set so that if the left rotator 20a is stopped and displayed with the symbol “cherry”, the other rotators 20b and 20c are stopped regardless of the symbol. Has been. Furthermore, the symbol combination corresponding to the “replay combination” is set to the symbol combination “replay-replay-replay”. In S50 of FIG. 4, it is determined whether or not the rotation of each cylinder 20a, 20b, 20c is stopped and the symbol combination obtained on the effective line corresponds to any one of these symbol combinations. And when it is judged that it does not correspond to any symbol combination (namely, it is not winning) (S60: no), it returns to the top process (S10) of the game control process of FIG. 4, and again. Wait until a game medal is bet. When it is confirmed that a bet is made (S10: yes), the above-described series of processing is executed again.

  On the other hand, if it is determined that any winning is achieved (S60: yes), first, it is determined whether or not the winning combination is a replay combination (S60). If the replay role has been won (S60: yes), the number of game medals inserted in the game that won the replay role is automatically re-inserted (S70), and then the game control process of FIG. Returning to the top processing (S10), it is determined whether or not a game medal has been betted. If not, the process waits until a game medal is bet again.

  On the other hand, if the winning game combination is not a replay combination (S60: no), “BB role”, “RB role”, “tin small role”, “plum small role”, “cherry small role” Therefore, a process of paying out the number of game medals corresponding to the winning game player (medal payout process) is executed (S80). Such processing is performed by determining the number of game medals to be paid out inside the main control board 200 and then outputting a control signal from the main control board 200 to the medal payout device 118.

  When the game medals are paid out in this way, it is next determined whether or not the winning game combination is the “RB combination” (S100). If the RB combination has been won (S100: yes), after a regular bonus game is performed (S110), the process returns to the process of S10 and the above-described series of processes are executed. Here, the regular bonus game (RB game) is the following game. Until a predetermined number of games are played (for example, 12 games) or until a predetermined number of times is won (for example, until 8 times are won), the number of combinations of symbols for establishing a game combination is increased. The probability of winning in the lottery is also set to a high probability. For this reason, in the regular bonus game, the player can acquire a large amount of game medals, and the game state is advantageous to the player. During the regular bonus game, the RB role or BB role is not won.

  On the other hand, when it is determined that the winning game combination is not the “RB combination” (S100: no), it is determined whether or not it is the “BB combination” (S120). If the BB combination has been won (S120: yes), after playing the big bonus game (S130), the process returns to S10 and the above-described series of processes are executed. Here, the big bonus game (BB game) is a game state in which the above-described regular bonus game can be continuously generated a plurality of times until a predetermined number (for example, 465) of game medals are paid out. is there. In other words, the big bonus game is composed of an introductory game until the “RB role” winning is established and a regular bonus game after the “RB role” winning is established, and a predetermined number (for example, 465). Until the game medals are paid out, the introduction game and the regular bonus game are repeated. When the number of game medals paid out during the big bonus game reaches a predetermined number (for example, 465), the big bonus game ends. For this reason, the big bonus game can acquire a larger amount of game medals than the above-described regular bonus game, and is in a more advantageous game state for the player.

  On the other hand, when it is determined that the winning game combination is not “BB combination” (S120: no), it is not any of “Replay combination”, “RB combination”, and “BB combination”. In other words, the game medal has been paid out in S90 for winning the small role. Therefore, in this case, after returning to the first process (S10) of the game control process of FIG. 4 and determining whether or not a game medal has been betted, the following series of processes is repeated.

  As described above, in the gaming machine 1 according to the present embodiment, a game medal is inserted, the start lever 36 is operated, an internal lottery is performed, and the spinning cylinder stop buttons 38aa, 38b, 38c are pressed, and the respective spinning cylinders 20a, The game progresses by repeatedly stopping and displaying the symbols 20b and 20c with the symbol combination corresponding to the game combination won in the internal lottery. Here, the internal lottery is performed by updating the internal lottery random number at a constant period, detecting that the start lever 36 is operated, and acquiring the random number. Therefore, if the start lever 36 is operated in synchronization with the random number update cycle, it is possible to always win an internal lottery, and this can be used to perform an illegal act of paying out a large number of game medals. There is sex. In order to prevent such an illegal act, in the gaming machine 1 of this embodiment, when the start lever 36 is operated, the internal lottery random number is acquired by the following method.

D. How to get random numbers for internal lottery:
In the gaming machine 1 of the present embodiment, the operation of the start lever 36 is detected by a sensor, and an internal lottery random number is acquired. Therefore, in the following, first, the structure of the start lever 36 and the mechanism for detecting that the start lever 36 has been operated will be described, and then a method for receiving the random number for internal lottery will be described. .

D-1. Start lever structure:
FIG. 6 is a sectional view conceptually showing the structure of the start lever 36. FIG. 6A shows a state where the start lever 36 is not operated, and FIG. 6B shows a state where the start lever 36 is operated. As shown in the figure, the start lever 36 has a shape in which a cylindrical elongated shaft is connected to a spherical knob. The shaft is pivotally supported by the front door 2 at a position slightly from the tip from the middle, and can be rotated in the vertical direction up to a certain angle around the shaft 36g. Further, a long and narrow prismatic tip portion 36t is provided at the tip of the shaft, and this tip portion 36t penetrates the back surface side of the front door 2. Further, a disc-shaped holding portion 36h is provided in the middle of the tip portion 36t, and a spring 36p is attached in a compressed state between the holding portion 36h and the back surface of the front door 2. . For this reason, the start lever 36 and the tip end portion 36t are always in a state of receiving a force from the spring 36p via the holding portion 36h, and by this spring force, the start lever 36 is as shown in FIG. It is held in a neutral state.

  Further, when the player operates the knob of the start lever 36 in either the up or down direction, as shown in FIG. 6B, the start lever 36 and the tip portion 36t rotate about the shaft 36g. For this reason, when the knob is pushed downward, the tip end portion 36t moves greatly upward, and conversely, when the knob is pushed upward, the tip end portion 36t moves greatly downward. When the player stops the operation of the knob, the start lever 36 is returned to the neutral state shown in FIG. 6A by the force of the spring 36p, and the tip end portion 36t is also returned to the initial position. In the gaming machine 1 of the present embodiment, it is detected that the start lever 36 has been operated by detecting the movement (or position) of the tip portion 36t.

D-2. Mechanism to detect start lever operation:
FIG. 7 is an explanatory diagram showing a rough configuration of a mechanism for detecting that the start lever 36 has been operated in order to acquire an internal lottery random number. In the illustrated example, a light emitting diode 132a and a phototransistor 132b are provided on both sides of the tip portion 36t to form a so-called photo interrupter, and the start lever 36 is operated by optically detecting the movement of the tip portion 36t. It has been detected.

  In the following description, the detection sensor 132 called a so-called photo interrupter is used to detect the movement of the tip portion 36t. However, the detection sensor 132 is not limited to a photo interrupter as long as the movement of the tip portion 36t can be detected. In addition, any type of sensor can be used as the detection sensor 132. For example, it is possible to use a so-called magnet pickup sensor that uses the electromagnetic induction effect for detection, a Hall sensor that uses the Hall effect, or the like.

  FIG. 7A shows the positional relationship between the start lever 36, the light emitting diode 132a, and the optical transistor 132b, and how the light emitting diode 132a and the optical transistor 132b are connected to the power supply board 280 and the main control board 200. It is explanatory drawing shown notionally. As shown in the drawing, the positions of the light emitting diode 132a and the phototransistor 132b are the positions of the tip 36t of the start lever 36 when the start lever 36 is not operated (in the neutral state shown in FIG. 6A). Is set to a position just between the light emitting diode 132a and the phototransistor 132b. The light emitting diode 132a and the phototransistor 132b are supplied with power from a sensor power supply circuit 130, which will be described later, provided on the power supply board 280, and the output from the phototransistor 132b is generated by a random number provided on the main control board 200. This is supplied to the circuit 206. A random number for internal lottery is supplied from the random number generation circuit 206 toward the CPU 201 mounted on the main control board 200. Since the random number generation circuit 206 periodically generates random numbers for internal lottery, the random number generation circuit 206 of this embodiment constitutes one aspect of the “random number generation means” in the present invention. In addition, since the sensor power supply circuit 130 supplies pulsed power to operate the detection sensor 132, the sensor power supply circuit 130 according to the present embodiment includes the “operating power supply unit” and the It constitutes an aspect of “pulse generation means”. Furthermore, since the CPU 201 mounted on the main control board 200 obtains the internal lottery random number based on the detection signal from the detection sensor 132, the CPU 201 of the present embodiment performs the lottery. It constitutes one aspect of the “lottery means” of the present invention.

  FIG. 7B is a circuit diagram showing the electrical configuration of the light emitting diode 132a and the optical transistor 132b. As is well known, the light-emitting diode 132a is an element that emits light when a prescribed power is supplied, and the phototransistor 132b is a kind of switching element. It has a function to connect the switch while receiving.

  Further, the sensor power supply circuit 130 mounted on the gaming machine 1 of the present embodiment varies the power supplied to the light emitting diode 132a and the phototransistor 132b, thereby preventing the above-described fraud. For the sake of convenience, the following description will be made assuming that constant power is supplied in the same manner as the normal gaming machine 1.

  If constant power is supplied to the light emitting diode 132a, light is always emitted from the light emitting diode 132a. Here, when the tip portion 36t exists between the light emitting diode 132a and the optical transistor 132b, the light from the light emitting diode 132a is blocked by the tip portion 36t and does not reach the optical transistor 132b. Disconnected. As is apparent from the circuit diagram shown in FIG. 7B, when the phototransistor 132b is in a disconnected state, the output voltage from the phototransistor 132b is in a high voltage state. On the other hand, when the tip 36t does not exist between the light emitting diode 132a and the phototransistor 132b, the light from the light emitting diode 132a reaches the phototransistor 132b, and the phototransistor 132b enters a connection state. The output voltage from the phototransistor 132b is in a low voltage state. As described above, when constant power is supplied to the light emitting diode 132a and the optical transistor 132b, when the start lever 36 is moved by moving the start lever 36, the output voltage of the optical transistor 132b fluctuates at that moment. This can be detected.

  On the other hand, the sensor power supply circuit 130 mounted on the gaming machine 1 of this embodiment has a voltage at which the photointerrupter can operate normally (that is, both the light emitting diode 132a and the phototransistor 132b can operate normally). Voltage) and a voltage at which the photointerrupter cannot operate normally (that is, a voltage at which either the light emitting diode 132a or the optical transistor 132b cannot operate normally) are supplied to the light emitting diode 132a and the optical transistor 132b. Supply. For this reason, even if the start lever 36 is operated and the tip portion 36t moves, it is possible to detect that the start lever 36 has been operated if the power that allows the photo interrupter to operate normally is not supplied. It is not possible to detect that the start lever 36 has been operated until power that can be normally operated is supplied.

  It should be noted that the power supplied from the sensor power supply circuit 130 toward the light emitting diode 132a and the phototransistor 132b can be any power as long as the detection sensor 132 varies between power that can operate normally and power that cannot operate normally. In this embodiment, a pulse that switches from a voltage at which the detection sensor 132 cannot operate to a voltage at which the detection sensor 132 can operate is supplied in a form that is output at random timing.

E. Principles that can prevent fraud:
Next, the principle that can prevent fraud with the above-described configuration will be described. As a preparation for this, in a normal gaming machine, fraudulent acts can be performed by operating the start lever 36 at a constant cycle. Briefly explain why.

  FIG. 8 is an explanatory diagram showing the reason why an illegal act is possible by operating the start lever 36 at a constant period in a normal gaming machine. As shown in the upper part of FIG. 8, in a normal gaming machine, the detection sensor 132 of the start lever 36 is always in an operating state. For this reason, when the start lever 36 is operated from OFF to ON, it is detected immediately and a detection signal is supplied to the random number generation circuit 206. The random number generation circuit 206 generates 65536 random numbers one after another. When a detection signal is received, the random number generated at that time is output to the CPU 201 of the main control board 200 as an internal lottery random number.

  Since the random number generated here is 65536 ways and always constant, the random number generation circuit 206 repeatedly generates 65536 kinds of random numbers at a constant period. Therefore, if the start lever 36 is operated in the same cycle as the cycle in which the random number is updated, the detection signal is always output at the timing when the same random number is generated, and the same internal lottery random number can always be obtained. Of course, it is almost impossible to operate the start lever 36 at the same period as the random number update period. However, if a special instrument incorporating a random number update period is used, this can be done. Therefore, it is possible to always win a specific game player and illegally pay out a large number of game medals.

  In contrast, in the gaming machine 1 of the present embodiment, the power supplied to the detection sensor 132 (here, the photo interrupter) is changed to switch the state of the detection sensor 132 between the operating state and the non-operating state. Therefore, it is possible to prevent fraud using special equipment. Hereinafter, this point will be described.

  FIG. 9 is an explanatory diagram showing the principle that can prevent fraud by varying the power supplied to the detection sensor 132. As described above with reference to FIG. 7, in the gaming machine 1 according to the present embodiment, electric power whose voltage fluctuates is supplied from the sensor power supply circuit 130 to the detection sensor 132. The non-operating state is always switched. The upper part of FIG. 9 conceptually shows how the operation state of the detection sensor 132 is switched.

  Next, as shown in the middle of FIG. 9, the start lever 36 is operated from OFF to ON. If the operation timing happens to be during the operation of the detection sensor 132, this can be detected immediately and a detection signal can be output. The operation cannot be detected. If the start lever 36 is still operated when the detection sensor 132 switches from the non-operating state to the operating state, it is detected for the first time that the start lever 36 has been operated, and the detection signal Is output. That is, in this case, there is a slight time lag from when the start lever 36 is operated until the detection signal is output. In this embodiment, since the pulse voltage output from the sensor power supply circuit 130 is output at random timing, the deviation time from when the start lever 36 is operated until the detection signal is output is It is different every time. For this reason, even if the start lever 36 is operated with the same cycle as the random number update cycle using a special instrument, a different random number for internal lottery is acquired every time, and the internal lottery is always won. It becomes possible to prevent fraud.

  As described above, when the state of the detection sensor 132 is switched from the non-operating state to the operating state, the case where the start lever 36 is still in the ON state has been described. However, when the sensor state is switched, It may also occur when the start lever 36 has already returned to the OFF state. In fact, among the players, there are many players who operate the hit lever at a rate of several times per second when operating the start lever 36. When the start lever 36 is operated in this way, the start lever 36 may already be turned off when the state of the detection sensor 132 is switched from the non-operating state to the operating state. FIG. 10 is an explanatory diagram showing how the internal lottery random number is acquired when the start lever 36 is operated many times in such a short time.

  In the illustrated example, the start lever 36 is operated in the ON state three times continuously for a relatively short period. Here, the first operation is performed when the detection sensor 132 is in the non-operating state, the operation is completed before the detection sensor 132 is switched to the operating state, and the start lever 36 is returned to the OFF state. Therefore, the first operation is not detected. The second operation is performed almost simultaneously when the state of the detection sensor 132 switches to the operating state, and the lever operation is detected almost simultaneously when the start lever 36 is turned on. Therefore, in the illustrated example, a detection signal is output almost simultaneously with the second operation of the start lever 36, and an internal lottery random number is acquired. Actually, how many times the lever is operated to determine whether the detection signal is output is determined by the timing at which the operation state of the detection sensor 132 is switched, the interval at which the start lever 36 is operated, the period in which the detection lever 132 is ON, and the like. , Every game is different. For this reason, as in the case shown in FIG. 9, even if the start lever 36 is operated at exactly the same period as the random number update period, a different random number for internal lottery is acquired for each game. It becomes possible to prevent.

  As described above, in the gaming machine 1 of the present embodiment, the power supplied to the detection sensor 132 for detecting that the start lever 36 has been operated is the power that can be used by the detection sensor 132 and the operation that cannot be performed. By varying the power to the appropriate power, the timing at which the detection signal is output with respect to the timing at which the start lever 36 is operated is varied, thereby preventing illegal acts. Therefore, although it is necessary to vary the power supplied to the detection sensor 132, the start lever 36 does not need to be modified at all such as adding new parts. In addition, if a pulse generation circuit is used, it is possible to change the power supplied to the detection sensor 132 very easily, and the pulse generation circuit is a widely used circuit with extremely high reliability. is there. For this reason, it is possible to prevent fraud without sacrificing the reliability of failure. In addition, the renovation required for that purpose can be done with a very simple refurbishment that fluctuates the power supply, so it can be applied very easily even when measures are taken to prevent fraudulent acts on existing swivel-type gaming machines. It is.

F. Modified example:
Various modifications exist in the above-described embodiment. Hereinafter, these modified examples will be briefly described.

F-1. First modification:
In the above-described embodiments, the power supplied to the detection sensor 132 has been described on the assumption that a pulsed voltage is supplied at random timing. However, the pulse voltage need not always be generated randomly. For example, even when pulses are generated at a constant period, the period at which pulses are generated may be set to a period that is slightly out of phase with respect to the period at which random numbers are updated. In this way, even if the start lever 36 is operated at the same cycle as the random number update cycle, the time from when the start lever 36 is operated until the detection signal is output is shifted, and the length of the shift time is also the same as that of the game. Since it is different every time, fraud can be effectively prevented.

F-2. Second modification:
In the above-described embodiment, the pulsed voltage waveform power is supplied from the sensor power supply circuit 130 to the detection sensor 132. However, the detection sensor 132 can operate and cannot operate. However, it is not always necessary to supply power in such a form that the voltage waveform changes in a pulse shape. For example, the power generated by using the power in the process of converting the AC power source to the DC power source by the power supply board 280 may be supplied to the detection sensor 132.

  FIG. 11 is an explanatory view conceptually showing a state in which power to be supplied to the detection sensor 132 is generated inside the power supply board 280. As described above, the power supply board 280 is a board that supplies DC power of a predetermined voltage to various boards such as the main control board 200, the sub-control board 220, the door board 240, and the rotor board 260. This DC power supply is generated in the following manner inside the power supply board 280 by drawing in a 100 V single-phase AC power supply.

  First, a 100-V single-phase AC power supply is passed through a full-wave rectifier circuit to generate a 100-V pulsating power supply. A full-wave rectifier circuit is a circuit that inverts the sign of only the negative voltage portion of the AC power source and converts it into a positive voltage, and can be configured very simply by combining diodes. FIG. 11 conceptually shows how alternating current is converted into pulsating flow by a full-wave rectifier circuit. Since the pulsating flow obtained in this way has a waveform in which the voltage fluctuates greatly, it is converted into a waveform having a substantially constant voltage through a smoothing circuit. FIG. 11 conceptually shows how a pulsating flow with a large voltage fluctuation is converted into a substantially constant voltage by a smoothing circuit. The voltage of the DC power source thus obtained is transformed to a specified voltage and supplied to various substrates.

  In the sensor power supply circuit 130 of the second modified example, the pulsating flow generated by the full-wave rectifier circuit of the power supply board 280 is taken in, and the maximum voltage slightly exceeds the operation specified voltage (or the operation specified voltage of the detection sensor 132). The obtained pulsating voltage may be supplied to the detection sensor 132 after being transformed so that the voltage becomes a voltage. FIG. 11 shows a state in which the operation regulation voltage of the detection sensor 132 is 5V and is transformed to a pulsating flow of approximately 5V.

  In this way, since the pulsating electric power whose voltage value fluctuates from the operation specified voltage value of the detection sensor 132 to 0 V can be supplied to the detection sensor 132, the detection sensor 132 is in an operation state and a non-operation state. Will repeat. If the detection sensor 132 happens to be in an operating state when the start lever 36 is operated, a detection signal is immediately output. If the detection sensor 132 is in an inactive state when the start lever 36 is operated, a delay occurs. The detection signal is output at the same timing. As a result, the time from when the start lever 36 is operated until the detection signal is output varies, so even if the start lever 36 is operated in synchronization with the internal lottery random number update period, the start lever 36 is always operated. It is not possible to win a predetermined game player by internal lottery, and it is possible to effectively prevent fraud. Note that the power supply board 280 in the second modification example generates full-wave rectification of the AC voltage supplied from the outside to generate the operating power of the gaming machine 1. Therefore, the power supply board 280 of the second modification constitutes one aspect of the “power supply circuit” of the present invention. In the second modification described above, the AC voltage is full-wave rectified by the full-wave rectifier circuit. However, the AC voltage may be half-wave rectified by the half-wave rectifier circuit. Even in this case, since the pulsating electric power whose voltage value fluctuates can be supplied to the detection sensor 132, the time from when the start lever 36 is operated until the detection signal is output is varied. be able to.

F-3. Third modification:
In the various embodiments described above, it has been described that the power from the sensor power supply circuit 130 is supplied to both the light emitting diode 132a and the phototransistor 132b that constitute the detection sensor 132. However, as long as the detection sensor 132 can be switched between the operation state and the non-operation state, the power from the sensor power supply circuit 130 is not necessarily supplied to the light emitting diode 132a and the phototransistor 132b.

  FIG. 12 is a circuit diagram showing a state in which power from the sensor power supply circuit 130 is supplied in the third modified example. In the illustrated example, the power from the sensor power supply circuit 130 is supplied only to the light emitting diode 132a, and the transistor operation regulation voltage (here, 5V) is supplied to the optical transistor 132b. In such a configuration, the phototransistor 132b is always in an operating state, but the power supplied to the light emitting diode 132a varies between a voltage at which the light emitting diode can emit light and a voltage at which the light emitting diode cannot emit light. The entire 132 repeats an operation state and a non-operation state. For this reason, even if the start lever 36 is operated in synchronization with the update cycle of the internal lottery random number, it cannot always be won by the internal lottery, and illegal acts can be effectively prevented.

  In FIG. 12, the power of the sensor power supply circuit 130 is supplied to the light emitting diode 132a and the operation-defined power supply is supplied to the phototransistor 132b. However, the power of the sensor power supply circuit 130 is supplied to the phototransistor 132b. It is also possible to supply operation-defined power to the light emitting diode 132a. In this case, the light-emitting diode 132a is always in an operating state, but the phototransistor 132b is switched between a state where light can be detected and a state where it cannot be detected. And the non-operating state are repeated. For this reason, even if the start lever 36 is operated in synchronization with the internal lottery random number update cycle, it is possible to effectively prevent an illegal act of always winning the internal lottery.

  In the various embodiments described above, the voltage on the high voltage side supplied to the detection sensor 132 is described as being varied. However, it is sufficient that the detection sensor 132 can be varied between the operating state and the non-operating state. It is also possible to change the voltage on the low voltage side (ground side).

  FIG. 13 is a circuit diagram showing an aspect in which the voltage on the ground side of the detection sensor 132 is varied. Although FIG. 13 shows the case where the ground side voltage of the light emitting diode 132a is varied, the ground side voltage of the phototransistor 132b may be varied, and furthermore, the light emitting diode 132a and the phototransistor 132b It is also possible to change the ground-side voltage together.

  In the example shown in FIG. 13, when the voltage on the ground side of the light emitting diode 132a is low, a current flows through the light emitting diode 132a, the diode emits light, and the detection sensor 132 is in an operating state. When the side voltage is high, the potential difference does not occur at both ends of the light emitting diode 132a, so that the diode does not emit light, and the detection sensor 132 is in an inoperative state. For this reason, since the detection sensor 132 as a whole is switched between an operating state and a non-operating state, it is possible to effectively prevent an illegal act performed by operating the start lever 36 in synchronization with the update cycle of the internal lottery random number. It becomes possible.
