Abstract

<P>PROBLEM TO BE SOLVED: To prevent a fraud using a so-called sensory device in a slot machine. <P>SOLUTION: A slot machine includes a sensor provided in a stop switch thereof and detecting an approach of an article thereto. The slot machine measures a time from a time when detecting the approach of the article to the stop switch based on an output of the sensor till the turn-on of the stop switch, converts the measured time into a numerical value and synthesizes the numerical value and an extracted lottery random number. The lottery is executed based on the synthesized numerical value. The synthesis processing can complicate a forecast of the random number. Even in a game having failed by pressing the start switch, an operation related to the stop switch is reflected to a next lottery of the game so as to eliminate a so-called thrown game. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a gaming machine, a lottery random number generation method for a gaming machine, and a program. In particular, the present invention relates to a technique for generating random numbers for lottery based not only on the operation of the start switch but also on the operation of the stop switch.

  A slot-type gaming machine (hereinafter referred to as a “gaming 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 the 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. For example, as shown in FIG. 15, the random number generator (counter) sequentially generates numerical values from 0000 to FFFF (hexadecimal) at a constant cycle. The output of the counter that is constantly changing is shown by assuming that the start switch is pressed down (in FIG. 15, the signal rise timing t1 and t3: the start switch press signal is positive logic, and the signal goes high when pressed down. And a lottery process is performed using the value as a random value (at time t1, the value of code A is output as a random value, and at time t3, the value of code B is output as a random value). The cycle of updating the counter output is very short, and even if it is known that the random number value has periodicity, it is difficult for the human industry to obtain the desired value. The counter output could be regarded as a pseudo-random number.

  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 can skillfully operate the start switch using any device to increase the lottery probability beyond a predetermined value cannot be denied. For example, a low-frequency treatment device (hereinafter referred to as “sensory device”) is attached to the arm, and the timing of operating the start switch is adjusted by periodically stimulating the muscles of the arm, and similar random values are obtained repeatedly It was thought to do.

  Since the repetition period of the random number generator (counter) is constant (T), the same random number value can be obtained in principle by setting the push switch depression period TS to an integral multiple of T. It seems that cheating is performed by adjusting the period of stimulation by the sensory sensor. Although it is forbidden to operate the start switch with the help of any device, the detection is not easy. It is required to take measures on the gaming machine side.

  As techniques for making it difficult to predict random numbers to be acquired in the lottery, there are the following techniques.

Japanese Patent Application Laid-Open No. 2005-66306 “Machine Machine, Game Machine Winning Judgment Method and Program” Random numbers related to lottery so as not to be advantageous even if a so-called sensory device is used to operate the start switch of the game machine at a certain timing. The purpose of this is to change the update period to be difficult to predict. In a gaming machine comprising a rotating reel, a stop switch for stopping the rotation of the rotating reel, a reel driving unit for driving the rotating reel, and a reel position detecting unit for detecting the rotational position of the rotating reel. A random number update stop signal generation unit that instructs the generator to stop or restart the update of random numbers at a predetermined opportunity. For example, the random number updating is stopped based on a signal from the stop switch, and the random number updating is restarted based on the rotating reel stop signal from the reel driving unit or the reel position detecting unit.

JP 2005-185525 A “Game Machine and Signal Delay Device” Using a so-called sensory device, it is possible to defend against an illegal act of pressing a start switch at regular intervals in accordance with the timing of winning content. The start signal sent by operating the start switch is delayed for an indefinite time by the start signal delay circuit.

JP-A-2005-348809 “Game Machine” It is difficult to aim at a specific random number and to avoid fraud. A random number is acquired at the timing when the initial indicating the reference rotation position of the reel reel passes the sensor. In addition, among the plurality of spinning reels, the spinning reels that take in the sensor signal are changed every game, or the respective rotation activation times are selected randomly or based on numerical values set in advance in the time table, Furthermore, the mounting position of the sensor for detecting the initial is changed for each gaming machine.

  1 and 2, reference numeral 100 denotes a gaming machine. As shown in FIG. 1, the gaming machine 100 can be opened and closed by a hinge or the like on the gaming machine main body 120 and one side of the front surface of the gaming machine main body 120. And a front door 130 attached thereto. As shown in FIG. 1, a game display unit 131 is provided substantially in the center of the front door 130, and a medal insertion slot 132 for a player to insert medals is provided at the lower right corner of the game display unit 131. Provided below the medal slot 132 is a reject switch 133 for forcibly discharging a jammed medal inserted from the medal slot 132 to the outside of the gaming machine 100.

  Further, a start switch 134 for starting a game is provided at the lower left of the game display unit 131, and three stop switches 140 are provided corresponding to each of the three reels (rotating cylinders). A bet switch 137 is provided in a table-like portion on the upper side of the start switch 134 and the stop switch 140 so that the player can play a game by operating instead of inserting medals. A medal payout port 135 is provided at the center of the lower end of the front door. A liquid crystal display device is provided on the right side of the game display unit 131.

  As shown in FIG. 2, the gaming machine main body 120 is fixed to the inner bottom surface, stores a plurality of medals therein, and stores the stored medals at a payout port 135 provided on the front surface of the front door 130. A hopper device 121 for paying out the sheets one by one is installed. An upper portion of the hopper device 121 is provided with a hopper tank 122 that opens upward and stores a plurality of medals therein. Inside the gaming machine main body 120, a reel unit 203 including three rotating reels is installed at a position where the game display unit 131 comes when the front door 130 is closed. The game display unit 131 is provided with an opening through which a player can see the symbols of each rotating reel of the reel unit 203. A power supply unit 205 is provided between the upper hopper unit 121 and the reel unit 203.

  As shown in FIG. 2, the medal (coin) selector 1 is attached to the back side of the front door 130 on the back side of the medal slot 132 provided on the front surface of the front door 130. This medal selector 1 rolls the medal toward the hopper device 121 while detecting the passage of the medal inserted from the medal insertion slot 132, and has a different diameter medal or iron or iron whose outer diameter is different from the predetermined dimension. This is an apparatus for selecting and removing illegal medals made of an alloy and selecting and eliminating a predetermined number or more of medals that can be inserted per game.

The medals distributed by the medal selector 1 are returned to the player from the payout port 135 via the derivation path 136.

FIG. 3 is a functional block diagram of the gaming machine 100 according to the first embodiment of the invention.
In this figure, the display about the power supply system is omitted. The gaming machine 100 includes a main board 10 and a sub board 20 that operates in response to a command from the main board 10 as main processing devices. At least the main substrate 10 is accommodated inside the case so that it cannot be contacted from the outside, and is sealed so that traces remain when these substrates are removed.

  The main board 10 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 10 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 main board 10 includes a winning lottery means 10a, a time measuring unit 10b, and a time storage unit 10c. The winning lottery means 10a performs an internal lottery process based on a signal from the start switch 134 (details will be described later). Based on sensors S1 to S3, which will be described later, the time measuring unit 10b waits for the time from when an object (player's finger) approaches the stop switch 140-1 to 140-3 until the stop switch is pressed (stopping from approaching the object). Measure the time until switch-on. The time storage unit 10c temporarily stores the time so that the time measured by the time measurement unit 10b can be combined with the random value extracted by the next press of the start switch 134.

  The gaming machine includes three rotating reels (not shown), and the first stop switch 140-1 to the third stop switch 140-3 correspond to each reel. The order in which the player presses the three stop switches 140-1 to 140-3 is arbitrary, and may be pressed in any order. In the following description, when any one of the three stop switches 140-1 to 140-3 is first pressed (turned on) and the rotating reel stops, it is called a first stop and is turned on at that time. The stop switch is called a first stop switch. Similarly, the second stop when the stop reel is stopped next time when another stop switch is pressed, the stop switch turned on at that time is the second stop switch, and the remaining one stop switch is pressed to rotate the reel. A stop switch that is turned on at that time is called a third stop switch. As described above, since the order in which the player presses the three stop switches 140-1 to 140-3 is arbitrary, the first stop switch 140-1 to the third stop switch 140-3 and the first to third stop switches The correspondence is not constant.

The time measurement unit 10b detects that an object (usually a player's finger) has approached any one of the stop switches 140-1 to 140-3 based on the output of any of the sensors S1 to S3, and then The time until the stop switch is turned on is measured, and the time is stored in the time storage unit 10c as the time until the first stop. The switch that is turned on at this time is the first stop switch. Similarly, the time until the next stop switch is turned on is the time until the second stop. The switch that is turned on at this time is the second stop switch, and the remaining one stop switch is turned on. The time is the time until the third stop, and the switch that is turned on at this time is the third stop switch.
Note that the time measurement unit 10b measures is not limited to the time from the first stop to the third stop. The time measurement unit 10b detects that an object has approached at least one of the stop switches 140-1 to 140-3, and then turns on at least one of the stop switches 140-1 to 140-3. The time until may be measured. Specifically, the time is as follows.
-Measure the time from when an object approaches the mth stop switch until the nth stop switch is turned on. Here, m and n are 1, 2, 3 and m <n, and (m, n) is any combination of (1, 2), (1, 3), (2, 3). Incidentally, the time from the first stop to the third stop is (m, n) = (1, 1) (2, 2) (3, 3).

  The sub board 20 is for receiving a command signal from the main board 10 and notifying the result of the internal lottery and performing various effects. The sub-board 20 includes a CPU that performs a control operation in accordance with 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. Only one command flows from the main board 10 to the sub board 20, and conversely, no command is issued from the sub board 20 to the main board 10.

  The main board 10 includes a start switch 134, a bet switch 137, first to third stop switches 140-1 to 140-3, a reel unit (including a reel driving device) 203, a reel position detection circuit 71, A hopper driving unit 80, a hopper 81, and a medal detection unit 82 for counting the number of medals paid out from the hopper 81 (these constitute the hopper device 121 described above) are connected.

  The start switch 134, the bet switch 137, and the three stop switches 140-1 to 140-3 are provided on the switch board SWB, and the switch board SWB and the main board 10 are connected to each other. The switch board SWB is provided with first to third sensors S1 to S3. These sensors are provided in the vicinity of the first stop switch to the third stop switch 140-1 to 140-3, respectively, and that the object (player's finger) has approached the switch and the distance to the object. It is a sensor which detects. The first to third sensors S1 to S3 will be described in detail later. In FIG. 3, the first to third stop switches 140-1 to 140-3 are shown, but may be referred to as the stop switch 140 when it is not necessary to distinguish them. Similarly, the first to third sensors S1 to S3 may also be referred to as sensors S.

  Peripheral substrates such as a liquid crystal control substrate 200 for controlling the liquid crystal display device, a speaker substrate 201, and an LED board 202 for electrical decoration are connected to the sub substrate 20. Although not shown in FIG. 3, a liquid crystal display device is connected to the liquid crystal control board 200. The liquid crystal control board 200, the speaker board 201, and the LED board 202 constitute an effect display unit. Speakers do not display with sound, but there is no need to distinguish visual and auditory from the viewpoint of the effect of production, both can be handled together. Will be included.

  As described above, the main board 10 and the sub board 20 are configured around the CPU and include a ROM, a RAM, an I / O, and the like. The CPU receives a player's operation and reads a program stored in the ROM to perform a predetermined operation. Specifically, the rotation and stop of the three rotating reels built in the reel unit 203 are controlled based on the operation of the start switch 134 and the stop switch 140, and the display of lamps, speakers, and the like are controlled. Temporary data necessary for the operation of the CPU is RAM (generally RAM is a volatile memory, and data is lost in principle when the power is turned off. There is a case where a power source is prepared. In this case, data is not lost even if the power source is cut off). The CPU performs a predetermined operation in accordance with a program recorded in the ROM, records temporary data necessary for processing in the RAM, and reads out and refers to the recorded data as necessary.

  A player who wants to enjoy a game with a gaming machine can first borrow a medal, which is a game medium, from a medal lending machine (not shown) or the like, and insert a medal directly into the medal insertion slot 132 of the medal insertion device. The start switch 134 is a lever positioned obliquely below the rotary reel, and starts driving the reel unit 203 on condition that a game medal is inserted. The drive of the reel unit 203 is stopped by the stop switch 140. The reel unit 203 is composed of three rotating reels. Each rotating reel includes a rotating drum made of a synthetic resin and a tape-like reel tape attached around the rotating drum. A plurality of (for example, 21) symbols are displayed on the outer peripheral surface of the reel tape.

  The ROM of the main board 10 stores the game processing procedure executed by the gaming machine 100 as a sequence program, and stores a winning probability table, a symbol table, a winning symbol combination table, and the like. Has been. The winning probability table is divided so that the random number values extracted by the random number generator (random number generator and random number extractor described later) are divided into each winning mode, and a certain range of numerical values generated by the random number generator. Data for dividing the random number extracted from the inside into each winning mode is stored. That is, the winning probability table has an area divided for each winning mode corresponding to the entire area of random numbers taken by the random number generator. For example, a range of 0 to a certain number is divided into a plurality, one division (region) is excluded, and the other division (region) is set as winning 1, winning 2,.

  The random number generator has a random number generation function that generates pseudo random numbers by rapidly updating numerical values in a certain range, and a sampling function that extracts an arbitrary random number value 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. In this specification, “random number” means the whole series of values generated by the random number generator, and “random number” means any value arbitrarily extracted from the series of random numbers. And For example, when the random number generator generates arbitrary numerical values such as r1, r2, r3, r4, r5,..., The whole of r1, r2, r3, r4, r5,. (To be precise, a random number sequence), and a sampled value (for example, r3, usually one value is extracted) is a random value. In the following description, “random number value” is also referred to as “random number data”.

  The extracted random number data is collated with each of the winning determination area data divided for each winning mode in all areas corresponding to the random number generated from the random number generator, and the extracted random data is assigned to the winning mode to which the extracted random number data belongs. The corresponding winning is determined. For example, it is determined which category (region) in the winning probability table the extracted random number value belongs to, and if the category is, for example, a category of winning 1, it is determined as “winning 1”. Similarly, if the extracted random number value belongs to a category (area) that is out of the winning determination table 6, 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. Various winnings occur under the probability according to the data setting of the winning probability table, and the symbol stop control is performed. For example, the business hours of the day are not affected by the skill of the player. The total medal payment rate is maintained almost constant.

  FIG. 4 is a block diagram of the winning lottery means according to the embodiment of the invention. At least some of the functions of the winning lottery means (for example, the determination unit 5 and the winning determination table 6) are realized by the above CPU executing a program stored in the ROM of the main board 10 or by hardware such as an IC. The As shown in FIG. 4, the winning lottery means includes a random number generator 3, a random number extractor 4, a determination unit 5, and a winning determination table 6.

  The winning lottery means further includes a combining unit 7 that combines the random number extracted by the random number extractor 4 with the time from the first stop to the third stop read from the time storage unit 10c. The combining unit 7 outputs, for example, the remainder when the product of the time from the first stop to the third stop multiplied by the extracted random number value is divided by a predetermined value. The operation of the combining unit 7 will be described in detail later. In this way, pressing of the start switch 1340 of each game and operations regarding the three stop switches 140-1 to 140-3 are reflected in the lottery result.

  The random number generator 3 generates a random number for winning lottery within a predetermined area. For example, a counter that receives a clock signal and generates an arbitrary numerical value with a predetermined probability in a range of 0 to a certain number (for example, 0000 to FFFF (hexadecimal)) according to the clock signal.

  The random number extractor 4 extracts the random number generated by the random number generator 3 with the signal of the start switch 134. The random number generator 3 continuously generates random numbers at predetermined intervals, and a part of them is extracted by the random number extractor 4.

  The winning determination table 6 has an area divided for each winning mode corresponding to the entire area of random numbers taken by the random number generator 3. For example, a range of 0 to a certain number is divided into a plurality, one division (region) is excluded, and the other division (region) is set as winning 1, winning 2,.

  The determining unit 5 refers to the random number data combined by the combining unit 7 with the lottery probability data in the winning determination table 6. 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 3, and the winning corresponding to the winning mode to which the random number data belongs is determined. Is. For example, it is checked which category (region) of the winning determination table 6 the synthesized random value belongs to, and if the category is, for example, a category of winning 1, it is determined as “winning 1”. Similarly, if the synthesized random number value belongs to the category (area) that is out of the winning determination table 6, 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.

  FIGS. 5A to 5C are explanatory diagrams of the attachment positions of the first to third sensors S1 to S3 according to the embodiment of the invention. FIGS. 5A to 5C are plan views (schematic diagrams) of any one of the three stop switches 140-1 to 140-3. If a plan view of the three stop switches 140-1 to 140-3 is drawn, three stop switches having the same structure are arranged side by side. However, since these three are exactly the same figure, in order to avoid complexity, FIG. 5 (a) to 5 (c) show only one stop switch (the stop switch arrangement interval in an actual gaming machine is narrow, so if the scale is accurate, FIG. 5 (a) to (c) However, adjacent stop switches should be displayed, but FIGS. 5A to 5C are schematic diagrams and do not accurately reflect the actual stop switch arrangement of the gaming machine. ) To (c), it should be understood that the display of adjacent stop switches is omitted). Reference numeral 140 in FIGS. 5A to 5C represents an arbitrary one of the three stop switches 140-1 to 140-3. Similarly, it should be understood that the symbol S indicates any one of the first to third sensors. In addition, the sensor S can be provided not only in each of the three stop switches 140-1 to 140-3 but also in only one or two stop switches. Based on the above, the mounting positions of the first to third sensors S1 to S3 shown in FIG. 3 are the same, and therefore the first to third sensors S1 to S3 are referred to as “ This is referred to as “sensor S”. Similarly, the first to third stop switches 140-1 to 140-3 are referred to as “stop switch 140”.

  The sensor S detects that the player's finger has approached the stop switch 140 (particularly, that the player's finger has approached the surface as the operation unit) in a non-contact manner. The distance between the switches 140 may also be measured (it is only necessary to know whether the object is within a predetermined range, and it is not essential to measure the distance to the object). In other words, the sensor S detects that the player's finger has approached a predetermined range (for example, 2 cm) from the stop switch 140. An example of how to attach the sensor S that realizes such a function is shown in FIGS. FIGS. 5A to 5C are schematic plan views of the stop switch 140 viewed from above. In these drawings, the upper side is the outside of the gaming machine, the lower side is the inside of the gaming machine, and reference numeral 130 indicates the thickness (cross section) of the front door.

  FIG. 5A shows a state in which a photo interrupter is provided as the sensor S at a predetermined position (for example, a position 2 cm away) of the stop switch 140. A photo interrupter is a device in which a light emitting element (light emitting diode, etc.) S-LED and a light receiving element (phototransistor, photodiode, etc.) S-PD are arranged to face each other and the presence of an object between them is detected without contact. It is. If the light L from the light emitting element S-LED reaches the light receiving element S-PD, it can be determined that there is no object, and if it does not reach, the object (player's finger) is present.

  FIG. 5B shows a state where the sensor S is provided in the vicinity of the stop switch 140. The sensor used for this is a sensor (displacement sensor) that can detect not only the presence or absence of an object but also the distance to the object. In addition, since the conventional pyroelectric sensor which detects the infrared rays which a human body emits cannot measure distance, it is unsuitable for this use.

  Displacement sensors include a sensor that irradiates an object with light and detects the object and distance based on the intensity of the reflected light, and a triangulation system that measures distance based on the displacement of the position of the reflected light. Some of them detect an object and a distance by the intensity of the reflected wave by applying an ultrasonic wave to the object. There is also an eddy current type. An eddy current displacement sensor uses a high-frequency magnetic field. A high-frequency current is caused to flow through a coil inside the sensor head to generate a high-frequency magnetic field. If there is an object to be measured in this magnetic field, An eddy current in the direction perpendicular to the passage of magnetic flux flows on the surface of the object, and the impedance of the sensor coil changes. The eddy current displacement sensor measures the distance by the change of the oscillation state due to this phenomenon.

  As shown in FIG. 5C, the sensor S may be provided inside the stop switch 140. Since the tip of the stop switch 140 is made of acrylic or the like and transmits infrared rays, the player's finger can be detected by providing an optical displacement sensor inside.

  Next, the operation of the gaming machine according to the first embodiment of the present invention will be described with reference to the flowcharts of FIGS.

  FIG. 6 is a flowchart of the internal lottery process. FIG. 7 is a flowchart of the time measurement process. 5 and 6 are performed by the main substrate 10.

  A description will be added to FIG.

S1: It is determined whether or not the start switch 134 is pressed.

S2: S1 becomes YES at the timing when the start switch 134 is pressed, and the random number is extracted from the random number generator 3. The extracted value is a random value. Specifically, the CPU of the main board 10 performs an interrupt process based on the signal of the start switch 134 and gives a signal to the random number extractor (latch) 4, and the value output by the random number generator 3 at that time is set. Get it.

S3: Read the time from the first to the third stop stored in the time storage unit 10c. Since overwriting is performed in the time storage unit 10c, the read time is measured in the previous game. The time storage unit 10c is, for example, a RAM.

S4: The first to third stop times read in S3 and the random value obtained in S2 are combined. Specifically, the CPU of the main board 10 executes processing. There are various ways of synthesis. There are methods based on arithmetic operations and logical operations, and methods using a table stored in a ROM or the like.

  Here, for example, the product of the time from the first to the third stop (in ms units) and the random value is obtained, and the remainder for 65536 (16 bits) is used as the synthesized random value. However, the random number generator 3 generates a 16-bit random number.

It is assumed that the time until the first stop read in S3 is 1000 ms, the time until the second stop is 500 ms, and the time until the third stop is 1200 ms. It is assumed that the random value acquired in S2 is 16372. Synthesize random values according to the following formula.
(Time to first stop) * (Time to second stop) * (Time to third stop) * (Extracted random number value)% 65536 = 1000 * 500 * 1200 * 16372% 65536 = 47104
However,% shows a remainder calculation.

S5: Winning determination is performed based on the synthesized random value. Since the corresponding selection determination is a known process, the description thereof is omitted.

  A description will be added to FIG.

S10: Since the first measurement is performed, the parameter i = 1 is set. Since the time from the first to the third stop is measured, the time measuring unit 10b repeats the measurement three times in total.

S11: The time measuring unit 10b monitors the outputs of the first sensor S1 to the third sensor S3.

S12: It is determined whether or not an object (player's finger) is approaching any one of the stop switches. Specifically, if the sensor detects that the object is within a predetermined range (for example, within 2 cm), it is determined as YES.

S13: Start a timer (not shown) (implemented by hardware or software) and start time measurement.

S14: It is determined whether or not the stop switch, that is, the stop switch provided with the sensor that detects the approach of the object is pressed (turned on).

S15: When YES in S14, the timer is stopped and the timer value at that time is stored in the time storage unit 10c. When the value of the parameter i is 1, 2, 3, the stored values are the time until the first stop, the time until the second stop, and the time until the third stop, respectively.

S16: It is determined whether time measurement has been performed three times. If it is less than three times (NO), i is increased by 1, and then the processing from S11 is repeated. If the number of times has been reached, the process is terminated.

  The processing of FIGS. 6 and 7 can be applied to the whole of the three stop switches 140-1 to 140-3 as described below, or can be applied individually. In the case of (1), for example, the numerical value to be compared in S16 (3 in FIG. 7) may be changed.

(1) The sensor S is provided in any one of the three stop switches 140-1 to 140-3, and the processes of FIGS. 6 and 7 are applied to the stop switch 140 provided with the sensor S.

(2) The sensors S1 to S3 are provided in each of the three stop switches 140-1 to 140-3, and the processes of FIGS. 6 and 7 are applied to each of the sensors.

  According to the embodiment of the invention, since the random number value extracted by the conventional start switch and the numerical value obtained based on the operation relating to the stop switch are synthesized, it is possible to make it difficult to predict the random number value. Also, even in a game that was unfairly won by pressing the start switch, the numerical value obtained based on the operation related to the stop switch is reflected in the next game lottery, so there is no so-called abandoned game, and more various operations are reflected. By performing a lottery in real time, there is an effect that the fun as a gaming machine increases.

Embodiment 2 of the Invention
FIG. 8 is a block diagram of a gaming machine according to the second embodiment of the invention. In FIG. 8, the same or corresponding parts as those in FIG. 3 are denoted by the same reference numerals, and the description thereof is omitted.

Reference numeral 10d denotes a numerical value generation unit that is provided on the main board 10 and generates a numerical value based on the time measured by the time measurement unit 10b (the time stored in the time storage unit 10c). The numerical value generated by the numerical value generating unit 10d is taken as an initial value into the random number generator 3 of the winning lottery means.
As described in the first embodiment of the invention, the time measurement unit 10b measures the following time.
-Measure the time from when an object approaches the mth stop switch until the nth stop switch is turned on. Here, m and n are 1, 2, 3 and m <n, and (m, n) is any combination of (1, 2), (1, 3), (2, 3). Or (m, n) = any combination of (1, 1) (2, 2) (3, 3) (these correspond to the time from the first stop to the third stop) ).

  FIG. 9 is a block diagram of the winning lottery means 10a according to the second embodiment of the invention. In FIG. 9, the same or corresponding parts as those in FIG. 4 are denoted by the same reference numerals, and the description thereof is omitted.

  The random number generator 3 takes in the numerical value generated by the numerical value generation unit 10d as an initial value based on the pressing signal of the third stop switch, and thereafter generates a random number based on the initial value.

  FIG. 10 shows an example of input / output terminals of a counter used as the random number generator 3. Although this figure shows a 4-bit counter IC, the same applies to an 8-bit counter. The four terminals of preset inputs -1 to -4 shown in FIG. 10 receive signals from the numerical value generator 10d. Similarly, the reset input terminal receives a signal from the third stop switch (for example, a “third release” signal that is turned off from on). When a signal is received at the reset input terminal, the counter of FIG. 10 takes in the initial random number value at that timing. Then, counting is continued based on the initial random number value. Note that the counter of FIG. 10 has first and second clock signal input terminals, but only one of them is used.

  FIG. 11 is a flowchart of the internal lottery process. FIG. 12 is a flowchart of the time measurement process. FIG. 13 is a flowchart of numerical value generation processing.

  A description will be added to FIG. The process of FIG. 11 is the same process as a conventional gaming machine.

S1: It is determined whether or not the start switch 134 is pressed.

S2: S1 becomes YES at the timing when the start switch 134 is pressed, and the random number is extracted from the random number generator 3. The extracted value is a random value.

S5 ': Winning determination is performed based on the extracted random number value. Since the corresponding selection determination is a known process, the description thereof is omitted.

  A description will be added to FIG.

S10: Since the first measurement is performed, the parameter i = 1 is set. Since the time from the first to the third stop is measured, the time measuring unit 10b repeats the measurement three times in total.

S11: The time measuring unit 10b monitors the outputs of the first sensor S1 to the third sensor S3.

S12: It is determined whether or not an object (player's finger) is approaching any one of the stop switches. Specifically, if the sensor detects that the object is within a predetermined range (for example, within 2 cm), it is determined as YES.

S13: Start a timer (not shown) (implemented by hardware or software) and start time measurement.

S14: It is determined whether or not the stop switch, that is, the stop switch provided with the sensor that detects the approach of the object is pressed (turned on).

S15: When YES in S14, the timer is stopped and the timer value at that time is stored in the time storage unit 10c. When the value of the parameter i is 1, 2, 3, the stored values are the time until the first stop, the time until the second stop, and the time until the third stop, respectively.

S18: It is determined whether i = 1, that is, at the time of the first stop. If it is at the time of the 1st stop, the random number of the random number generator 3 at that time will be extracted and memorize | stored in the numerical value generation part 10d (S19). This process may be executed when i = 2 or 3. You may abbreviate | omit the process of S18 and S19.

S16: It is determined whether time measurement has been performed three times. If it is less than 3 times (NO), i is increased by 1 (S17), and then the processing from S11 is repeated. If the number of times has been reached, the process is terminated.

  A description will be added to FIG.

S20: It is determined whether or not the third stop switch has been pressed, that is, whether or not the stop switch associated with the rotating reel that has been rotated to the end has been pressed.

S21: When YES in S20, the time from the first to the third stop stored in the time storage unit 10c and the random number value extracted at the first stop are read.

S22: The initial value is obtained by synthesizing the first to third stop times read in S21 and the extracted random number values. Specifically, the CPU of the main board 10 executes processing. There are various ways of synthesis. There are methods based on arithmetic operations and logical operations, and methods using a table stored in a ROM or the like.

  As in the first embodiment of the invention, for example, the product of the time from the first to the third stop (in ms units) and the random number value is obtained, and the remainder for 65536 (16 bits) is used as the synthesized random number value. However, the random number generator 3 generates a 16-bit random number.

It is assumed that the time until the first stop read in S3 is 1000 ms, the time until the second stop is 500 ms, and the time until the third stop is 1200 ms. Assume that the random value acquired in S2 is 56666. Synthesize random values according to the following formula.
(Time to first stop) * (Time to second stop) * (Time to third stop) * (Extracted random value)% 65536 = 1000 * 500 * 1200 * 56666% 65536 = 39936
However,% shows a remainder calculation.

S23: The generated initial value is set in the random number generator 3. Specifically, a signal is input to the reset terminal of the counter, and the signals appearing in the preset inputs -1 to -4 are taken in. Thereafter, the random number generator 3 starts counting from the replaced initial value. For example, if the value of the random number generator 3 at that time is “99”, “99” is replaced with “33”. Counting starts from the replaced value. That is, “33” “34” “35” “36”. The following processing is the same as the conventional processing. FIG. 14 is an example of a timing chart showing the output of the random number generator 3, in which the content of the random number generator 3 is replaced with D at the timing of the symbol R (S23 execution timing in FIG. 13).

  By the above processing, the pressing of the start switch 134 and the pressing of the three stop switches 140 of each game are reflected in the lottery result. As can be seen from FIG. 14, the regular periodicity of the output of the random number generator 3 is broken at the timing of the code R. For this reason, it becomes difficult to predict random values, and illegal acts can be prevented.

  The second embodiment of the invention has the same effects as the first embodiment.
