Description

  The present invention relates to a gaming machine, a winning determination method for a gaming machine, and a program.

  A gaming machine such as a slot machine is provided with a medal slot so that a player can enjoy a game by inserting a predetermined number of medals. The medals necessary for the game can be borrowed with a medal lending machine provided in the game hall, and the game can be started by inserting it into the medal slot of a desired gaming machine.

The operation of the conventional gaming machine was as follows.
First, when the start switch is operated, the start switch is turned on. In response to this, a lottery process is performed by a winning lottery means inside the gaming machine. Here, when a predetermined combination is won, a winning flag is set. The rotating reel starts to rotate. When the stop switch is operated, the stop switch is turned on. Then, the rotation of the corresponding rotating reel is stopped. After the stop switches corresponding to all the rotating reels are operated, whether or not the winning symbols corresponding to the winning flag are aligned on the effective winning line while the winning flag is established, that is, whether or not the winning is confirmed. Is determined. When it is determined that the winning is confirmed, a medal corresponding to the winning symbol is paid out.

  For example, when the evaluation of the lottery process is out of place, it is set so that the predetermined symbols are not aligned (so-called kicking), and when winning, the predetermined symbols are aligned on the condition that the stop switch is pressed at a predetermined timing. (So-called pull-in). In other words, only when winning in the lottery process, medals are paid out by winning a winning pattern under a predetermined condition, but when not winning, medals are paid out regardless of how the stop switch is operated. There is no. This is to keep the medal payout at a certain probability. In order to realize this, a random number generator is used in the lottery process.

  A random number generator of a gaming machine generates a random number using a counter, for example. The random numbers generated in this case have a certain degree of regularity, and therefore have a predictable aspect. The possibility that the player could make the lottery probability over a predetermined value by skillfully operating the start switch could not be denied.

  This will be described with reference to FIG. In the symbol lottery, random numbers are acquired at the timing when the start lever is pressed (t1 and t2 in FIG. 14). The random numbers are periodically generated within a fixed period and in a fixed range (0000 (hexadecimal) to FFFF (hexadecimal) in the figure). If the interval T between the start lever pressing timings t1 and t2 is set to an integral multiple of the random number generation cycle, the acquired random numbers a and a ′ can be made the same. If the timing is thus devised to obtain a desired random number, the winning probability can be increased. Actually, it seems that the interval T is made an integral multiple of the random number generation cycle by attaching a low frequency treatment device to the arm and shaking the finger at regular intervals, or hitting the start lever with a solenoid that operates at regular intervals. . Such fraudulent acts are called “solenoid goto”. The loss incurred by such halls cannot be ignored.

  Accordingly, the present invention provides a gaming machine, a gaming machine winning determination method, and a program in which a specific random number cannot be obtained even if the start switch is devised, and a specific player is not advantageous in terms of a lottery probability. The purpose is to do.

  The present invention relates to a gaming machine comprising a winning lottery means for performing lottery based on a predetermined signal and making a winning determination based on the lottery result, wherein the winning lottery means generates a random number for winning lottery, A random number extractor that extracts a random number generated by the random number generator based on a plurality of triggers; a random number synthesis unit that synthesizes and outputs a plurality of random numbers extracted by the random number extractor; A winning determination table that stores correspondence relationships in advance, and a determination unit that determines whether or not the random number synthesized by the random number synthesizing unit with reference to the winning determination table is present or the type of winning is determined. It is.

  For example, the random number synthesis unit may add the plurality of random numbers and output a lower bit of the sum.

  The present invention relates to a gaming machine comprising a winning lottery means for performing lottery based on a predetermined signal and making a winning determination based on the lottery result, wherein the winning lottery means generates a random number for winning lottery, One of a random number extractor that extracts a random number generated by the random number generator based on a plurality of triggers, a storage unit that stores a plurality of random numbers extracted by the random number extractor, and a random number stored in the storage unit A random number selection unit that selects and outputs, a winning determination table that preliminarily stores a correspondence between a numerical value related to a lottery and a winning, and whether or not a random number selected by the random number selecting unit with reference to the winning determination table is won Or the determination part which determines the kind of winning a prize is provided.

  The random number selection unit, for example, reads a random number from the random number generator when selecting a random number, and selects a random number stored at an address corresponding to the random number. Alternatively, the random number selection unit sequentially selects the random numbers in the storage unit.

  More specifically, the random number extraction unit extracts a random number from the start switch, the stop switch, the bet switch, the medal insertion detection of the medal selector, and the reel index detection in whole or in part. It is.

This invention is a method of performing a lottery based on a predetermined signal and performing a winning determination based on the lottery result,
A first step of acquiring a random number for each of the plurality of triggers based on signals related to the plurality of triggers;
A second step of generating a single random number by combining a plurality of random numbers acquired in the first step;
And a third step of determining the presence or absence of the random number synthesized in the second step or the type of the winning with reference to a winning determination table prepared in advance.

This invention is a method of performing a lottery based on a predetermined signal and performing a winning determination based on the lottery result,
A first step of acquiring a random number for each of the plurality of triggers based on signals related to the plurality of triggers;
A second step of selecting any of the plurality of random numbers obtained in the first step;
And a third step of determining whether or not the random number selected in the second step has been won or the type of the winning with reference to a winning determination table prepared in advance.

The program according to the present invention is recorded on a recording medium, for example.
Examples of the medium include EPROM devices, flash memory devices, flexible disks, hard disks, magnetic tapes, magneto-optical disks, CDs (including CD-ROMs and Video-CDs), DVDs (DVD-Videos, DVD-ROMs, DVD-s). RAM), ROM cartridge, RAM memory cartridge with battery backup, flash memory cartridge, nonvolatile RAM cartridge, and the like.

  In addition, a communication medium such as a wired communication medium such as a telephone line and a wireless communication medium such as a microwave line is included. The Internet is also included in the communication medium here.

  A medium is a medium in which information (mainly digital data, a program) is recorded by some physical means, and allows a processing device such as a computer or a dedicated processor to perform a predetermined function. is there.

  According to the present invention, since a plurality of random numbers acquired at a plurality of occasions are synthesized or selected and the result is used for the lottery process, an error in the random number acquisition timing becomes large and it becomes difficult to acquire a desired random number. . Furthermore, it takes time to generate a plurality of opportunities, and the operation for generating them seems unnatural, so that it is difficult to perform fraud.

Embodiment 1 of the Invention
A gaming machine according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a gaming machine (slot machine) according to an embodiment of the invention.
A player who wants to enjoy a game with the slot machine 10 first borrows a medal as a game medium from a medal lending machine (not shown) or the like, and inserts a medal directly into the medal insertion slot 100 of the medal insertion device. The medal slot 100 is provided at a substantially central height position in front of the slot machine 10.

  The slot machine 10 has a square box-shaped housing 11. A square window-like display window 12 facing the player side is formed at the center and upper part of the casing 11. A symbol display window 13 through which the symbols 61 of the three rotary reels 40 can be seen is formed at the center of the display window 12 at the center. The bet switch 16 is a switch located below the rotary reel 40 and reduces the number of stored medals to replace medal insertion. The settlement switch 17 is a switch located obliquely below the rotating reel, and pays out the stored inserted medal. The start switch 30 is a lever positioned obliquely below the rotary reel 40 and starts driving the reel unit 60 on condition that a game medal is inserted or the bet switch 16 is inserted. The stop switch 50 is for stopping the driving of the reel unit 60. The reel unit 60 is composed of three rotating reels 40. Each rotary reel 40 includes a rotary drum made of synthetic resin and a tape-like reel tape 42 attached around the rotary drum. A plurality of (for example, 21) symbols 61 are displayed on the outer peripheral surface of the reel tape 42. Reference numeral 62 denotes a liquid crystal display unit for performing various effects.

  Inside the slot machine 10, although not shown, a control device for controlling the entire operation of the slot machine 10 is incorporated. Although not shown, the control device is configured around a CPU and includes a ROM, a RAM, an I / O, and the like. Then, the CPU operates by reading a program stored in the ROM, and controls the rotation and stop of the rotary reel 40 based on the operation of the start switch 30 and the stop switch 50, and also controls the display of lamps, speakers, and the like.

  As described above, the start switch 30 is a lever that is positioned obliquely below the rotary reel 40. The start switch 30 is subject to the insertion of a game medal or the bet switch 16, or from the previous game at the time of “Replay”. This is for starting the driving of the reel unit 60 on condition that the predetermined time elapses.

  The stop switch 50 is for stopping the driving of the reel unit 60 as described above. Specifically, the stop switch 50 includes three switches corresponding to each rotary reel 40, and one stop switch 50 is disposed below each rotary reel 40. The operation of the stop switch 50 corresponding to the rotating reel 40 is set to stop the rotation of the corresponding rotating reel 40.

  When the start switch 30 is operated on the condition that the medal is inserted or the bet switch 16 is inserted, or on the condition that a predetermined time has elapsed from the previous game at the time of “replay”, the reel unit 60 is driven, and the three units The rotating reel 40 starts to rotate. Thereafter, when one of the stop switches 50 is operated, the rotation of the corresponding rotary reel 40 is stopped. When all three stop switches 50 are operated, the rotation of the three rotary reels 40 is stopped. At this time, when a preset symbol 61 is stopped on the effective pay line of the display window 12, a predetermined number of medals are paid out via the hopper unit 65. In addition, you may credit instead of paying out medals.

  Whether the control device described above has performed lottery processing based on a predetermined lottery probability when the rotation and stop of the rotary reel 40 are controlled based on the operation of the start switch 30 and the stop switch 50, and whether or not a winning qualification has been obtained. Including a winning lottery means (see FIG. 4 and its description). When the lottery result by the winning lottery means is a win, a winning flag is established, and the winning combination is established on the condition that the combination of the stopped symbols of the rotating reel 40 matches a predetermined winning symbol while the winning flag is established. It is determined so that the player is given a medal or a special game.

  FIG. 2 is a block diagram showing an electrical schematic structure of the slot machine 10. In this figure, the display about the power supply system is omitted. The slot machine 10 includes a main substrate 1 (first processing unit) and a sub-substrate 2 (second processing unit) that receives a command from the main substrate 1 and operates as a main processing device. At least the main substrate 1 is accommodated inside the case so that it cannot be contacted from the outside, and a sealing process is performed so that traces remain when the substrates are removed.

  The main board 1 is for performing an internal lottery in response to a player's operation, and processing such as reel rotation / stop and medal payout. The main board 1 includes a CPU that performs a control operation according to a preset program, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like.

  The sub-board 2 is for receiving a command signal from the main board 1 and notifying the result of the internal lottery and performing various effects. The sub-board 2 includes a CPU that performs a control operation according to a preset program corresponding to the command signal, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like.

  The sub-board 2 receives a command from the main board 1 and performs processing such as rendering according to the command. The flow of commands is only one from the main board 1 to the sub board 2, and conversely, no command or the like is issued from the sub board 2 to the main board 1.

To count the number of medals paid out from the random number generator 20, start switch 30, stop switch 50, reel drive unit 70, reel position detection circuit 71, hopper drive unit 80, hopper 81, hopper 81 on the main board 1. The medal detection unit 82 and the medal selector 83 are connected. A peripheral board (local board) such as a control board 200 of the liquid crystal display device 62, a speaker 201, and an LED board 202 is connected to the sub board 2. In FIG. 2, for convenience of explanation, the random number generation unit 20 is shown as a separate block from the main substrate 1, but the random number generation unit 20 may be provided in the main substrate 1. The random number generator 20 may be realized by a program (software) on the main board 1.
Hereinafter, these peripheral substrates / devices except for the start switch 30 and the stop switch 50 will be described.

  The random number generation unit 20 has a random number generation function for generating a pseudo random number by updating the numerical values in a certain range at high speed, and a sampling function for extracting an arbitrary random number from the generated random numbers in response to the player's operation. It is to be prepared. As a specific example, it is composed of a counter and a latch.

  The reel driving unit 70 is a circuit that drives a stepping motor (not shown) that rotationally drives the three reels 40. Each stepping motor is subjected to 1-2 phase excitation by the reel drive circuit 70 and rotates once when a drive signal having a predetermined number of pulses is supplied.

  The reel position detection circuit 71 is provided in the vicinity of the reel 40, receives an output pulse signal from a photo interrupter (not shown) for detecting the rotation position of the reel 40, detects the rotation position of each of the three reels 40, and detects it. A signal is output. A photo interrupter (not shown) detects a shielding plate provided on each reel 40 and generates a reset pulse every time each reel 40 rotates once. This reset pulse is given to the CPU of the main board 1 via the reel position detection circuit 71. In the RAM of the main board 1, a count value corresponding to the rotation position within one rotation range is stored for each reel 40, and when the CPU receives the reset pulse, the count value formed in the RAM is stored. Clear to “0”. By this clearing process, the deviation generated between the movement display of each symbol and the rotation of each stepping motor is eliminated every rotation. (Refer to FIG. 8 and FIG. 9 and the explanation for the reel unit)

  The hopper driving unit 80 is a circuit that drives a motor of a hopper 81 that stores medals and pays out the number of medals corresponding to the designated winning.

  The medal detection unit 82 is for counting the number of medals paid out from the hopper 81. The CPU of the main board 1 stops driving by the hopper driving unit 80 when the actually paid out medal count value received from the medal detection unit 82 reaches the predetermined payout number data corresponding to the winning. Finish paying out. A predetermined number of medals are paid out to the player by the hopper driving circuit 80 and the medal detection unit 82 based on a winning obtained as a result of the game.

  The medal selector 83 is for receiving a medal inserted into the medal insertion slot 100 and returning a non-standard medal to the medal return slot 304 and counting the number of regular medals inserted. When a medal is detected, the signal is sent to the main board 1.

The liquid crystal control board 200 is a circuit for driving the liquid crystal display unit 62.
The speaker 201 is for generating sound such as voice and sound effects.
The LED substrate 202 is a circuit for driving a display lamp and a back lamp (not shown).

  The liquid crystal display device 62 controlled by the liquid crystal control substrate 200 and the LED substrate 202 including the speaker 201 and the display lamp constitute an effect display device. This effect display device is for notifying a player of a prize or the like, or for teaching a user a specific small role during a certain game with some action during a so-called assist time (AT).

  FIG. 3 shows a block diagram of the random number acquisition mechanism according to Embodiment 1 of the present invention. FIG. 3 specifically shows the relationship among the main board 1, the random number generator 20, the start switch 30, and the stop switch 50 in FIG. Note that FIG. 3 shows a concept, and the actual connection may not necessarily be as shown in FIG. 3 or may be realized by software.

  In FIG. 3, three stop switches 50 are divided into a first cylinder stop button 50a to a third cylinder stop button 50c. Output signals from the first cylinder stop button 50a to the third cylinder stop button 50c and the start lever 30 are input to the random number generator 20 and the main board 1, respectively. When one of the four switches in FIG. 3 is pressed, the random number value (output of a counter not shown) at that time is latched and held, and the CPU of the main board 1 reads the latched random value. go. Then, the read random number value is stored in the buffer 1 a of the main board 1. In the conventional random number acquisition mechanism, random numbers are read when the start lever 30 is pressed. In contrast, the first embodiment of the present invention is characterized in that random numbers are read at the timing of pressing a plurality of switches. It should be noted that, as the random number reading timing, the bet switch 16 pressing timing, the medal selector 83 medal detection timing, the reel 40 index detection timing, and the like can be used.

  When one of the stop buttons 50a to 50c is pressed first after the third cylinder rotation starts, a pressing signal is output to the random number generator 20 and the CPU of the main board 1. The random number generator 20 latches the random number value at the timing of the pressing signal. The CPU receives the press signal, reads the random number value into the random number generation unit 20, and stores it in the buffer 1a. Similarly, when another stop button is pressed, a pressing signal is output to the random number generation unit 20 and the CPU, the random number generation unit 20 latches the random number value, and the CPU reads the random number value into the random number generation unit 20. The random number value is added to the data stored in the buffer 1a and then stored in the buffer. The random number value read from the random number generator 20 by the CPU when the start lever 30 of the next game is pressed is added to the data in the buffer 1a and then stored in the buffer. Therefore, the buffer 1a stores a total of four random numbers acquired at four triggers. The value is set as a symbol lottery random value.

  FIG. 4 is a block diagram of the winning lottery means. The random number generator 22 and the random number extractor 23 in FIG. 4 correspond to the random number generation unit 20 in FIG. 3, and the determination unit 24 to the random number synthesis unit 26 in FIG. 4 correspond to the main board 1 in FIG. The portion 20 may be provided in the main substrate 1). Specifically, the winning lottery means is realized by executing the program stored in the ROM of the main board 1 by the CPU and / or hardware. The configuration of the winning lottery means is not limited to that shown in FIG.

  The random number generator 22 generates a random number for winning lottery within a predetermined area. For example, an arbitrary numerical value is generated with a predetermined probability in a range of 0 to a certain number.

  The random number extractor 23 extracts a random number generated by the random number generator 22 at a timing when the start switch 30 or the stop button 50 is pressed. The random number generator 22 continuously generates random numbers at predetermined intervals, and a part of them is extracted by the random number extractor 23. This extracted random number is used as extracted random number data.

  The random number synthesis unit 26 synthesizes random numbers acquired at a plurality of occasions into one random number data. For example, the random numbers acquired at the four triggers in FIG. 3 are added and the total value is output. If the acquired random numbers are a1 to a4, the average value: (a1 + a2 + a3 + a4) / 4 is output, or the lower 16 bits of (a1 + a2 + a3 + a4) are output (in this case, the carry at the time of addition is ignored) ). When a1 to a4 are added, the total is larger by a maximum of 2 bits than the first random number, but since the number of bits in the winning determination table 25 remains the same, it cannot be used as it is. Therefore, by dividing by 4, the original number of bits is restored. Alternatively, it is the same if the upper 16 bits are used and the lower 2 bits are ignored.

  Note that the composition operation is not limited to addition. Other arithmetic operations and logical operations such as logical sum and logical product may be used.

  The winning determination table 25 has an area divided for each winning mode corresponding to the entire area of random numbers taken by the random number generator 22. For example, a range of 0 to a certain number is divided into a plurality, one division (area) is excluded, and the other division (area) is set as winning 1, winning 2,.

  The determination unit 24 refers to the random number data synthesized by the random number synthesis unit 26 with the lottery probability data in the winning determination table 25. That is, the random number data is collated with each of the winning determination area data divided for each winning mode in the entire random number area taken by the random number generator 22, and the winning corresponding to the winning mode to which the random number data belongs is determined. Is. For example, it is determined which category (area) of the winning determination table 25 the synthesized random number value belongs to, and if the category is, for example, a winning 1 category, it is determined as “winning 1”. Similarly, if the synthesized random number value belongs to the category (area) of the winning determination table 25, it is determined as “out”.

  For example, when the evaluation of the lottery process is out of place, it is set so that the predetermined symbols are not aligned (so-called kicking), and when winning, the predetermined symbols are aligned on the condition that the stop switch is pressed at a predetermined timing. (So-called pull-in). And if predetermined symbols are prepared, medals corresponding to winning symbols are paid out.

  Next, an outline of the operation of the slot machine having the above configuration will be described with reference to the flowcharts of FIGS. 5 and 6 and the timing chart of FIG.

S1: Preparations for starting the game process are made by inserting medals from the medal insertion slot 100 or pressing the bet button 16 in step S1 of FIG.
S1b: When the start switch 30 is operated, the start switch 30 is turned ON. The game is started by pressing the start switch 30.
S2: A lottery process is performed by the winning lottery means shown in FIG. Details of the lottery process are shown in FIG. The description will be described later.

S3: The rotation of the three rotary reels 40 is started.
S4: When any one of the stop switches 50 is operated, the stop switch 50 is turned on.

S4b: A random value is acquired when the stop switch 50 is pressed. Then, the obtained random number is added to the value stored in the buffer 1a, and the addition result is written in the buffer 1a (a1 to a3 in FIG. 7). Since this step is executed for each stop switch 50, the acquisition and addition of the random number value in this step is executed a total of three times.
S5: A rotation stop process for one rotary reel 40 corresponding to the pressed stop switch 50 is performed.

S6: It is determined whether or not the operation of the stop switch 50 corresponding to the three rotary reels 40 has been performed. When it is determined that the operation of the stop switch 50 corresponding to the three rotary reels 40 has been performed, the process proceeds to the next step S7.
S7: It is determined whether or not the winning symbols corresponding to the winning flag are aligned on the effective winning line while the winning flag is established, that is, whether or not the winning is confirmed. If it is determined that the winning is confirmed, the process proceeds to the next step S8.

S8: A medal corresponding to the winning symbol is paid out. Then, the process proceeds to next Step S9.
S9: When a prize is confirmed in a special game of a big bonus (BB) game or a regular bonus (RB) game, the game is counted in a state where the number of confirmed prizes of the special game is increased by one.

The lottery process in step S2 described above will be described using the flow of FIG.
S11: The random number is extracted from the random number generator 22 by the random number extractor 23 at the timing when the start switch 30 is pressed.

S12: A value is read from the buffer 1a, the extracted random number (a4 in FIG. 7) is added, and the result is stored again in the buffer 1a. By this process, a plurality (four) of random values acquired at a plurality (four) of triggers are synthesized. The random number a4 acquired by pressing the start switch 30 is acquired in the current game, but the random numbers a1 to a3 acquired by pressing the stop switch 50 are acquired in the previous game. In the first embodiment of the invention, the random number acquired in the previous game and the random number acquired in the current game are combined. If random numbers acquired across games are used, the prediction of random values becomes more difficult.
S13: The determiner 24 compares the synthesized random number with the winning determination area data in the winning determination table 25. Then, the process proceeds to the next step S14.

S14: The determination unit 24 determines which winning mode of the winning determination table 25 includes the extracted random number, and determines the evaluation of the lottery process. Then, the process proceeds to next Step S15.
S15: If the evaluation of the lottery process is out of place, for example, the predetermined symbols are set so as not to be aligned (so-called kicking), and in the case of winning, the predetermined symbols are set on condition that the stop switch is pressed at a predetermined timing. It is set to be aligned (so-called pull-in). Then, the lottery process ends.
S16: The buffer 1a is cleared in preparation for the next lottery process. Since the random number acquired in S4b of FIG. 5 is stored in the buffer 1a, part of the random number values (a1 to a3) are synthesized in the game. The partially synthesized random number value is used in the next game lottery process. In addition, the clear process of S16 is not essential, and there can exist an effect | action and effect which concerns on embodiment of this invention even if it does not perform the said process.

  The timing chart of FIG. 7 will be described. The random numbers are periodically generated within a fixed period and in a fixed range (0000 (hexadecimal) to FFFF (hexadecimal) in the figure). In the first embodiment of the present invention, random values are acquired at each of four timings t1 to t4 when the first cylinder stop button 50a to the start switch 30 are pressed. After obtaining the fourth random number at t4, the four random numbers are synthesized. Although t4 is a random number acquired in the current game, t1 to t3 are random numbers acquired in the previous game.

  As is clear from the above description, in Embodiment 1 of the present invention, random numbers acquired at a plurality of occasions are combined and used for the lottery process. In the above example, the random number acquisition opportunity is a total of four times, that is, the stop button of each of the three times of the previous game is pressed and the start lever of the current game is pressed, and the total value of the four random numbers is used as the symbol random number. In this way, the trigger for using the solenoid in fraudulent action is a total of four times of pressing the three rotation stop buttons and pressing the start lever, so the error in the intended random number acquisition timing increases (t1 to t4). The same random number cannot be obtained unless all the intervals of are made constant). As a result, the success rate of fraud is low. In addition, since it takes time to play, cheating becomes difficult, and the appearance of playing seems unnatural, so cheating is hard to do (when you move your finger between the start button and stop button, In the past, it was possible to leave the finger on the start button because it was only necessary to press the start button illegally, but it was illegal in the gaming machine according to the embodiment of the present invention. If you want to do something, you have to move your finger between the start and stop buttons frequently).

  As the random number read timing, the bet switch 16 pressing timing, the medal selector 83 medal detection timing, the reel 40 index detection timing, or the like can be used instead of or together with the start switch 30 and the stop switch 50.

  In order to facilitate understanding of the reel index detection timing, a specific configuration of the rotating reel (rotating drum) will be described with reference to FIGS. 8 and 9.

  As shown in FIG. 8, each of the reels 40 a to 40 c is configured as a rotary reel unit, and is attached to the frame 151 via a bracket 152. Each of the reels 40a to 40c has a reel band 154 attached to the outer periphery of a reel drum 153. The symbol row (design 61) is drawn on the outer peripheral surface of the reel band 154. Each bracket 152 is provided with a stepping motor 155, and the reels 40a to 40c are driven by the motor 155 to rotate.

  The structure of each reel 40a-40c is shown in FIG. A lamp case 156 is provided inside the reel drum 153 behind the reel band 154, and back lamps 157a, 157b, and 157c are attached to the three rooms of the lamp case 156, respectively. These back lamps 157 a to 157 c are mounted on a substrate 158 as shown in FIG. 9B, and this substrate 158 is attached to the back of the lamp case 156. A photo interrupter 159 is attached to the bracket 152. A photointerrupter is a case in which a light emitting element (such as a light emitting diode) and a light receiving element (such as a phototransistor or a photodiode) are arranged to face each other, and a detection groove is provided between them. The passage is detected without contact. The photo interrupter 159 detects that the shielding plate 160 provided on the reel drum 153 passes through the photo interrupter 159 as the reel drum 153 rotates. A signal from the photo interrupter 159 is input to the reel position detection circuit 71 in FIG.

  The back lamps 157a to 157c are individually controlled to be turned on by a lamp driving circuit (not shown). By turning on each of the back lamps 157a to 157c, among the symbols drawn on the reel band 154, three symbols located at the front of each of the back lamps 157 are individually illuminated from behind, and are respectively displayed on the symbol display window 13. Three symbols are displayed.

  The reel position detection circuit 71 receives the output pulse signal from the photo interrupter 159 and detects the rotational position of each reel 40. The photo interrupter 159 detects the shielding plate 60 and generates a reset pulse every time each reel 40 makes one rotation. This reset pulse is applied to the main board via the reel position detection circuit. In the RAM of the main board, the count value corresponding to the rotation position within one rotation range is stored for each reel 40, and when the CPU of the main board receives the reset pulse, this count formed in the RAM is stored. The count value is cleared to “0”. By this clearing process, the deviation generated between the movement display of each symbol and the rotation of each stepping motor 155 is eliminated every rotation. When the stop switch 50 is pressed, a signal for stopping the corresponding reel 40 is sent to the main board.

Embodiment 2 of the Invention
In the first embodiment of the present invention, random numbers are acquired at a plurality of occasions, and these are combined into one random number. In the second embodiment of the present invention, random numbers are acquired at a plurality of occasions, and one of these is selected and used for the lottery process.

  FIG. 10 shows a block diagram of a gaming machine according to the second embodiment of the invention. FIG. 11 is a block diagram of the winning lottery means. A plurality of buffers are provided according to the number of opportunities for random number acquisition. In FIG. 10, four buffers 1a-1 to 1a-4 are provided. One of these is selected by the random number selection unit 1b, and a lottery process is performed using the selected random number. The procedure for obtaining random numbers at the four occasions is the same as in the first embodiment.

  The random number selection unit 1b selects a random number in an appropriate manner when a lottery process is performed (for example, after the start switch 30 is pressed and a game is started). For example, select as follows.

(1) Select at random. For example, the random number of the random number generation unit 20 is read at the time of lottery processing, and which buffer is selected by the lower 2 bits. For example, if the lower 2 bits are 00, the buffer 1a-1 is selected, if it is 01, the buffer 1a-2 is selected, if it is 10, the buffer 1a-3 is selected, and if it is 11, the buffer 1a-4 is selected. .

(2) Select in order. For example, the buffers 1a-1, 1a-2, 1a-3, and 1a-4 are selected in this order. You may make it select according to the order of the address of a memory (it selects in descending order of address or ascending order).

(3) In addition, when the four random numbers are divided into even numbers and odd numbers, a small number is selected. When there are a plurality of them, the above procedure (1) or (2) is further used.

  FIG. 12 is a flowchart of the game process according to the second embodiment of the present invention. Compared with the process of FIG. 5, the process of FIG. 5 is different in that the random number acquired in S4c is simply stored in the corresponding buffer and is not synthesized (added) with the acquired random number.

  FIG. 13 is a flowchart of the lottery process according to the second embodiment of the invention. Compared with the process of FIG. 6, the process of FIG. 6 simply stores the random number acquired in S12 (when the start switch is pressed) in a corresponding buffer and does not synthesize (add) the acquired random number, and , S12b is different in that any one of the plurality of random numbers acquired in S12b is selected. Examples of the selection method are described in (1) to (3) above.

  According to the second embodiment of the invention, since any one of a plurality of random numbers acquired at a plurality of occasions is selected and the result is used for the lottery process, the error in the random number acquisition timing is increased, and the desired random number Acquisition becomes difficult. Furthermore, it takes time to generate a plurality of triggers, and the operation for generating a plurality of triggers looks unnatural, so that it is difficult to carry out fraud.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.

  Further, in the present specification, the term “unit” does not necessarily mean a physical means, but includes a case where the function of each unit is realized by software. Furthermore, the function of one part may be realized by two or more physical means, or the function of two or more parts may be realized by one physical means.
