Description

  The present invention relates to a spinning machine having a spinning cylinder, a gaming machine having a display device corresponding to the spinning cylinder, a fraud detection method for a gaming machine, and a program.

  Pachislot machines such as slot machines and pachinko machines have built-in microcomputers that control lottery, winning, payout, and production by programs. This type of gaming machine receives a player's operation, performs an internal lottery and a winning determination according to the lottery result, and also controls a game medium payout control according to the winning and a first processing unit (so-called main board) And a second processing unit (so-called sub-board) for receiving a command from the first processing unit and notifying the result of the internal lottery and performing various effects. 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.

  A block diagram of a conventional slot machine is shown in FIG. The main board 1 includes a start switch 30, a stop switch 50, a reel (rotating cylinder) driving unit 70, a reel (rotating cylinder) position detection circuit 71, a hopper driving unit 80, a hopper 81 for storing and paying out medals, and a hopper 81. A medal detection unit 82 for counting the number of medals paid out is connected. A peripheral substrate (local substrate) such as a control substrate 200, a speaker substrate 201, and an LED substrate 202 of the liquid crystal display device is connected to the sub substrate 2. Details of these will be described later.

  A liquid crystal display device, a speaker, a display lamp, and the like (not shown) 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 with a certain action during a certain game during a so-called assist time (AT). is there. (Assist Time (AT): Even if a specific small role is established, the player will not be refunded unless the symbols on the reels are aligned. After the big bonus ends (or at the time of establishment) to ensure payout by the small role) Alternatively, a lottery of assist time is drawn at any other opportunity, and if this is won, the player is instructed to perform an operation to establish a specific small role for a certain game with some action)

  FIG. 18 shows a process flowchart regarding the AT. A lottery is performed on the main board 1 (S10), and the winning combination of the lottery result is transmitted to the sub board 2 (S11). Sub-board 2 receives the winning combination (S20), determines whether the winning combination is an AT lottery combination, and if it is an AT lottery combination (YES in S23), performs AT processing (S26) to establish a specific small combination. Teach the player how to make it happen. If it is not the AT lottery (NO in S23), the process proceeds to the next process without performing the AT process.

  As with the AT, there is a gaming machine in which the weight of the winning rate is controlled by software on the sub-board 2 side. The sub-board 2 side is provided with a function for adjusting the protruding balls. Specifically, as described above, an instruction for obtaining a ball is displayed on the liquid crystal display device so that the player can easily obtain the ball if the player operates according to the instruction. This instruction is not always issued, and is issued when the AT lottery combination is met.

  By the way, there are those that try to exploit this function and get illegally. As shown in FIG. 17, an unauthorized device X is attached to a cable or connector between the main board 1 and the sub board 2, and an AT command (AT lottery role) originally issued in a specific case is issued from this apparatus X at all times. By this, you can always get the ball easily. The AT is designed so that even if it is won in the internal lottery, it cannot be won unless it is pushed in the pushing order, and this pushing order changes irregularly, so that it is not won so much. However, when an unauthorized device X is attached, the pressing order is notified every time and there is no loss of data. This is significantly unfair compared to the general player and may cause damage to the hall. Although it is only necessary to inspect the gaming machine and remove the unauthorized device, it is not preferable because the illegal activity continues until then. There is a limit to increasing the frequency of inspection of gaming machines.

Embodiment 1 of the Invention
A gaming machine according to Embodiment 1 of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a gaming machine (slot machine).

  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 position substantially on the right side of the center 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 rotating reels (rotating drums) 40 can be seen is formed in the center of the display window 12 at the center. The bet switch 16 is a switch located below the rotary reel (rotating drum) 40, and reduces the number of stored medals to replace medal insertion. The settlement switch 17 is a switch located to the left of the rotating reel (rotating drum), and pays out the stored inserted medal. The start switch 30 is a lever positioned obliquely below the rotary reel (rotating drum) 40, and starts driving the reel (rotating drum) unit 60 on condition that a game medal is inserted or the bet switch 16 is input. The stop switch 50 is for stopping the driving of the reel (rotating drum) unit 60. The reel (rotating drum) unit 60 includes three rotating reels (rotating drums) 40. Each rotating reel (rotating drum) 40 includes a rotating drum made of a synthetic resin and a tape-like reel (rotating drum) tape 42 attached around the rotating drum. A plurality of (for example, 21) symbols 61 are displayed on the outer peripheral surface of the reel (rotating drum) tape 42. Reference numeral 62 denotes a liquid crystal display unit for performing various effects.

  The start switch 30 is a lever that is positioned obliquely below the rotating reel 40 as described above, and is subject to the insertion of a game medal or the insertion of the bet switch 16 or “Replay”. In some cases, the reel (rotating drum) unit 60 starts to be driven on the condition that a predetermined time has elapsed since the previous game.

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

  When the start switch 30 is operated on the condition that a 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. The three rotating reels (rotating drums) 40 start to rotate. Thereafter, when one of the stop switches 50 is operated, the rotation of the corresponding rotating reel (rotating drum) 40 is stopped. When all three stop switches 50 are operated, the rotation of the three rotary reels (rotating drums) 40 stops. At this time, when a predetermined symbol 61 stops on the effective pay line of the symbol display window 13, a predetermined number of medals are paid out via a hopper unit (not shown). In addition, you may credit instead of paying out medals.

  The symbol displayed in the symbol display window 13 when the three rotating reels (rotating drums) 40 are stopped is referred to as a “stop outcome”. When the same symbol is aligned on the winning line (changes to 1, 3, or 5 depending on the number of medals inserted), the winning is made and medals are paid out.

  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 (first processing unit) 1 and a sub-substrate (second processing unit) 2 that receives a command from the main substrate (second processing unit) 2 as main processing apparatuses.

  The main board 1 is for performing an internal lottery in response to a player's operation, and processing such as rotation / stop of a reel (rotating drum) and payout of medals. The main board 1 includes a CPU that performs a control operation according to a preset program, and ROM and RAM that are storage means.

  When the main board 1 controls the rotation and stop of the rotating reel 40 based on the operation of the start switch 30 and the stop switch 50, a lottery for determining whether or not to win based on a predetermined lottery probability And a winning lottery means (not shown). A winning flag is established when the lottery result by the winning lottery means is a winning, and the combination of stop symbols of the rotating reel (rotating drum) 40 coincides with a predetermined winning symbol while the winning flag is established. The conditions are set so that the winning is confirmed and the player is given a medal or special game profit.

  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, and a ROM and a RAM that are storage means.

  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. In the following description, the case where the board for performing the game process is divided into the main board 1 and the sub board 2 will be described as an example. However, the main board 1 and the sub board 2 are separated from each other. Is not the essence of A main board that controls a plurality of reels, internal lottery, winning determination and game medium payout control, and processing such as production when the winning combination falls under the predetermined winning combination information related to internal lottery Needless to say, the sub-boards to be performed may be combined into one, and this is also included in the present invention.

  The sub-board 2 includes a consistency determination unit 2a, a correspondence information storage unit 2b, and an error notification unit 2c in order to detect whether or not a command (winning role) has been tampered with by an unauthorized device X. The consistency determining unit 2a compares the winning combination sent from the main board 1 with the stop symbols (stop appearance) of the three rotary reels (rotating cylinders) 40, thereby determining the consistency between them. The consistency determining unit 2a determines that the consistency between the winning combination and the stopping outcome is consistent, but determines that the winning combination is consistent with the stopping outcome (for example, When the sub-board 2 receives a winning combination that is not established), it is determined that the winning combination has been tampered with, and as a result, consistency has been lost. Then, the execution of the process by the winning combination is stopped (for example, the AT process is not performed even for the AT lottery combination), and an error is notified by the error notification unit 2c.

  The correspondence information storage unit 2b stores in advance a combination (or a combination that is not consistent) of the winning combination and the stoppage combination. Among the combinations of winning combinations and stoppages, those that are consistent are, for example, AT lottery combinations and their entire patterns as shown in FIGS. 8 and 9, which will be described later. This is a combination of possible stop outcomes. On the other hand, inconsistent combinations among winning combinations and stop appearances are combinations of stop appearances that cannot theoretically be taken for a specific winning combination. That is, the stop control of the spinning cylinder according to the winning combination (including the unsuccessful winning combination) won based on the result of the internal lottery, specifically, the so-called pull-in control that causes the winning combination to win the winning combination, So-called kicking control is performed so that no winning combination is won when winning. As a result, for all stop events, stop events that can be (can exist) in the winning combination (a combination of stop events corresponding to the winning combination) and impossible stop events (stop events corresponding to the winning combination) Stop combinations other than the above), and the number of stop events that can be filed for a particular winning combination is limited. Therefore, the above-mentioned stop outcome that cannot be obtained is a combination of stop outcomes that cannot theoretically be obtained. For example, an AT lottery combination and an arbitrary pattern other than those shown in FIGS. In the matched combination, there is no contradiction between the winning combination and the stop-out pair (no conflict in normal game machine operation). A combination that is not consistent results in a stoppage that is theoretically impossible for the winning combination (if it can happen, in the case of fraud), and there is a contradiction in the combination of the winning combination and the stopout. The consistency determination unit 2a refers to the correspondence information storage unit 2b to determine whether or not there is a match. For example, when the matched winning combination and the stop appearance combination are stored as a table in the correspondence information storage unit 2b, the table is searched using the stop outcome as a key, and the corresponding winning combination is obtained. When the searched winning combination matches the winning combination received by the sub-board 2 (when there are a plurality of searched winning combinations, they match some of them), it is determined that consistency is achieved. The table may be searched using the winning combination received by the sub-board 2 as a key, and it may be checked whether or not the searched stop event matches the actual stop event. If the correspondence information storage unit 2b stores inconsistent information, it is determined that no matching is achieved when the search results match.

  In FIG. 2, the consistency determination unit 2 a determines the winning combination sent from the main board 1 based on the output signals of the first sensor 162 and the second sensor 163 provided separately from the reel position detection circuit 71. It is compared with information (for example, output of a reel position detecting device such as a counter operated by output signals of the sensors 162 and 163). Usually, since the unauthorized device X is provided between the main board 1 and the sub board 2, the output information used by the consistency determination unit 2a is not subjected to falsification. In order to produce an effect, the stoppage is sent from the main board 1 to the sub board 2, but this is not used in the first embodiment of the present invention.

  2 shows a state in which the consistency determination unit 2a, the correspondence information storage unit 2b, and the error notification unit 2c are built in the sub-board 2 (which may be realized by a program of the sub-board 2). It is not limited to this. The main substrate 1 and the sub substrate 2 may be provided independently.

  The main board 1 includes a start switch 30, a stop switch 50, a reel (rotating cylinder) driving unit 70, a reel (rotating cylinder) position detection circuit 71, a hopper driving unit 80, a hopper 81 for storing and paying out medals, and a hopper 81. A medal detection unit 82 for counting the number of medals paid out is connected. A peripheral substrate (local substrate) such as a control substrate 200 of the liquid crystal display unit 62, a speaker substrate 201, and an LED substrate 202 is connected to the sub substrate 2. In FIG. 2, a first sensor 162 and a second sensor 163 for detecting the position of the reel are also connected to the sub-board 2. The sub-board 2 acquires the outcome information from the output signals of the sensors 162 and 163. Since the sensors 162 and 163 are provided on each of the plurality of reels, the sub-board 2 can acquire the stop position of each reel.

Hereinafter, these peripheral substrates / devices except for the start switch 30 and the stop switch 50 will be described.
The reel (rotating cylinder) driving unit 70 is a circuit that drives a stepping motor (not shown) that rotationally drives three reels (rotating cylinders) 40. Each stepping motor is excited by the 1-2 phase by the reel (rotating drum) drive circuit 70, and rotates once when a predetermined number of pulse drive signals are supplied.

  The reel (rotating cylinder) position detection circuit 71 is provided in the vicinity of the reel (rotating cylinder) 40 and receives an output pulse signal from a photosensor (not shown) for detecting the rotational position of the reel (rotating cylinder) 40. (Rotating cylinder) 40 detects each rotational position and outputs a detection signal thereof. A photo sensor (not shown) detects a shielding plate provided on each reel (rotor) 40 and generates a reset pulse every time each reel (rotor) 40 makes one rotation. This reset pulse is given to the CPU of the main board 1 via the reel (rotating cylinder) position detection circuit 71. The RAM of the main board 1 stores a count value corresponding to the rotation position within one rotation range for each reel (rotating cylinder) 40. When the CPU receives a reset pulse, it is formed in the RAM. This 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 is eliminated every rotation.

  The hopper driving unit 80 is a circuit that drives a motor (not shown) of the hopper 81 that stores medals and pays out the designated number of medals.

  The medal detection unit 82 is for counting the number of medals paid out from the hopper 81. When the medal count value actually paid out received from the medal detection unit 82 reaches the predetermined payout number data, the CPU of the main board 1 stops the driving by the hopper driving unit 80 and ends the medal payout. . The hopper drive circuit 80 and the medal detection unit 82 pay out a predetermined number of medals to the player based on the game result.

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

  The liquid crystal display unit 62, a speaker and a display lamp (not shown), etc. 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).

  The ROM of the main board 1 stores game processing procedures executed in the slot machine 10 as a sequence program, and also includes a winning probability table, a symbol (symbol) table, a winning symbol combination table, and the like. Has been stored. The winning probability table is divided so as to divide the extracted random number into each winning mode, and stores data for dividing a certain range of generated random numbers into each winning mode. In other words, the winning probability table has an area divided for each winning mode corresponding to all possible random number areas. 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 extracted random number data is collated with each of the winning determination area data divided for each winning mode in the entire random number area, and the winning corresponding to the winning mode to which the extracted random number data belongs is determined. For example, it is determined which category (region) of the winning probability table 5 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 an out-of-range category (region) in the winning determination table 5, 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. Since various types of winning are generated with the probability according to the data setting of the winning probability table, for example, the total medal within the business hours of the day is not influenced by the skill of the player. The payment rate is kept almost constant.

  In FIG. 2, X is an unauthorized device attached to the gaming machine by an unauthorized person. The unauthorized device X is often provided on a cable or connector connecting the main board 1 and the sub board 2. The unauthorized device X sends a command for notifying the sub-board 2 of information advantageous to the player to the sub-board 2 illegally (regardless of the processing of the main board 1). Since the purpose is not to disturb the game processing, even if there is an unauthorized device X, the sub-board 2 is changed from the main board 1 except that the specific command is altered (the normal role is changed to the AT lottery role). The command transmission to is performed normally.

Next, a specific configuration of the rotating reel (rotating drum) will be described.
As shown in FIG. 3, each reel (rotating cylinder) 40 a to 40 c is configured as a rotating reel (rotating cylinder) unit, and is attached to a frame 151 via a bracket 152. Each of the reels (rotors) 40 a to 40 c is configured by a reel (rotor) belt 154 attached to the outer periphery of a reel (rotor) drum 153. The symbol row (symbol 61) is drawn on the outer peripheral surface of the reel (rotating drum) band 154. Each bracket 152 is provided with a stepping motor 155, and each reel (rotating drum) 40a-40c is driven by these motors 155 to rotate.

  The structure of each reel (rotating drum) 40a-40c is shown in FIG. A lamp case 156 is provided inside the reel (rotor) drum 153 behind the reel (rotor) belt 154, and back lamps 157a, 157b, and 157c are provided in the three chambers of the lamp case 156, respectively. It is attached. These back lamps 157 a to 157 c are mounted on a substrate 158 as shown in FIG. 4B, and the 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 (rotor) drum 153 passes through the photo interrupter 159 as the reel (rotor) drum 153 rotates. A signal from the photo interrupter 159 is input to the reel (rotating cylinder) position detection circuit 71 of FIG.

  Apart from the photo interrupter 159, a first sensor 162 and a second sensor 163 are provided on the bracket 152. The first sensor 162 and the second sensor 163 are configured by, for example, a photo interrupter. The first sensor 162 outputs a passage detection signal of the shielding plate 160 similarly to the photo interrupter 159. The first sensor 162 detects one rotation of the reel 40. The shielding plate 160 functions as a reel rotation index. The second sensor 163 outputs a signal when the shielding plate 161 provided for each symbol (for example, provided at the boundary between the symbols) passes through the drum 153. The second sensor 163 detects the movement of the reel 40 corresponding to the symbol. The shielding plate 162 functions as an index for symbols provided on the surface of the reel 40. A specific example of the method for acquiring the output information using the first sensor 162 and the second sensor 163 will be described later.

  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 (rotor) band 154, the three symbols located at the front of each back lamp 157 are individually illuminated from behind, and the symbol display Three symbols are projected on each window 13.

  Next, an outline of the operation of the slot machine having the above-described configuration will be described with reference to a processing flowchart shown in FIG.

First, in step S1 shown in FIG. 5, when the start switch 30 is operated, the start switch 30 is turned on. Then, the process proceeds to the next step S2.
In step S2, a lottery process is performed by the main board 1. When winning, a winning flag will be established. Then, the process proceeds to the next step S3.

In step S3, rotation of the rotary reels (rotors) 40a to 40c starts. Then, the process proceeds to the next step S4.
In step S4, when the stop switch 50 is operated, the stop switch 50 is turned on. Then, the process proceeds to the next step S5.
In step S5, rotation stop processing of the rotary reel (rotating drum) 40 is performed. Then, the process proceeds to the next step S6.

In step S6, it is determined whether or not the operation of the stop switch 50 corresponding to the three rotating reels (rotating cylinders) 40 has been performed. When it is determined that the operation of the stop switch 50 corresponding to the three rotating reels (rotating drums) 40 has been performed, the process proceeds to the next step S7.
In step 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.

In step S8, medals corresponding to winning symbols are paid out. Then, the process proceeds to next Step S9.
In step S9, when a winning decision is made in a special game of a BB (Big Bonus) game or an RB (Regular Bonus) game, it is counted in a state where the number of winning decisions of the special game is increased by one.

  Next, the procedure for detecting falsification of the winning combination in the first embodiment of the invention will be described with reference to the flowchart of FIG. In the figure, S10 and S11 mean main substrate processing, and S20 to S27 mean sub-substrate processing.

S10: A lottery is performed on the main board 1 (the same process as S2 in FIG. 5).
S11: The winning combination of the lottery result is transmitted to the sub-board 2.
S20: The winning combination is received by the sub-board 2. Then, in order to determine whether or not the winning combination has been falsified, a winning combination falsification detection process (S21 to S27) is executed.
S21: Wait until the reel stops (for example, if the stop stops, the output of the second sensor 163 does not change, and when that state continues for a certain period of time), the stop board information is acquired by the sub board 2. Specifically, the CPU of the sub-board 2 determines the reel stop position based on the outputs of the first sensor 162 and the second sensor 163, and acquires the outcome information. Or the counter which operate | moves based on the output of the 1st sensor 162 and the 2nd sensor 163 is provided, and the outcome information is acquired by treating the count value as a stop symbol number.

S23: It is determined whether or not the winning combination is an AT lottery combination. If it is an AT lottery combination (YES in S23), the processing from S24 is performed in order to determine the consistency of the stoppage. Otherwise (NO in S23), the process ends without performing the process related to the AT lottery (S24 and subsequent steps), and the process returns to the main routine.
S24: The winning combination sent from the main board 1 is compared with the stop event information to determine the consistency between the two. If there is no contradiction between the winning combination and the stop event, it is determined that the two are consistent. However, if the winning combination is inconsistent with the stopping event (for example, if the winning event is not established in the stopped event, 2), it is determined that the winning combination has been falsified and as a result has become inconsistent.

  Preferably, in S24, a table of matched (or unmatched) combinations among the winning combinations and stop-out combinations is prepared in advance. For example, when a matched winning combination and stop combination are prepared as a table, the table is searched using the stop output as a key, and a corresponding winning combination (winning combination) is obtained. When the searched winning combination matches the winning combination received by the sub-board 2 (when there are a plurality of searched winning combinations, they match some of them), it is determined that consistency is achieved. The table may be searched using the winning combination received by the sub-board 2 as a key, and it may be checked whether or not the searched stop event matches the actual stop event. If the table does not match, the table is determined not to match when the search result matches.

S25: When matching is received according to the processing result of S24, the processing is terminated without performing error processing, and the processing returns to the main routine. If they do not match, the execution of the process by the winning combination is stopped (the AT process is not performed even if the winning combination is AT) and an error is notified (S27).

  According to the first embodiment of the present invention, the winning combination sent from the main board is compared with the stop-out information acquired based on the first sensor 162 and the second sensor 163, so that the reel (cylinder) is stopped. It is determined whether or not the outcome corresponds to the winning combination. If not, the process shifts to an error state without performing the process (AT process) corresponding to the winning combination. Therefore, when a command is tampered with by an unauthorized device, this is detected and notified, and no profit is given to an unauthorized person. The fraudulent board changes the winning combination command so that it is advantageous for winning the game (normal role → AT lottery role, etc.), but according to the first embodiment of the invention, the fraudulent action is ended effortlessly. be able to.

Example 1.
The consistency determination process will be described with reference to a specific example. The first embodiment is a method for determining based on the stop symbols of the three spinning cylinders 40a to 40c. In this case, all combinations of stop symbols that will be AT lottery combinations are stored in the table (or all patterns of stop events that are stopped in the case of incorrect selection are stored in the table). There is an advantage that can be reliably determined. On the other hand, the number of such combinations increases, the amount of data in the table increases, and it is difficult to implement if there is not enough memory capacity, and the processing load on the CPU increases.

  In FIG. 7, in order to simplify the description, it is assumed that each of the reels 40a to 40c has only five symbols (actually, the number of symbols on each reel is 21). The symbols of the reels 40a to 40c are the left, middle and right in FIG. 7, and the numbers given to the symbols indicate the numbers of the corresponding symbols. For example, it means that five symbols of No. 1 Seven, No. 2 Bell, No. 3 Replay, No. 4 Bell and No. 5 Watermelon are attached on the reel 40a. The same applies to the reels 40b and 40c. In a state where the reels 40a to 40c are stopped, three consecutive symbols among the first to fifth are displayed on the symbol display window 13 (because the symbols are attached to the circumference of the reel). No. 5 and No. 1 are continuous). The three symbols surrounded by thick lines in FIGS. 8 and 9 have such a meaning.

  Next, the AT lottery pattern will be described. For the sake of simplicity, it is assumed that the pressing order of the reels 40a to 40c is determined in advance and is the order of the reels 40a to 40c.

  8 and 9 show all patterns of the AT lottery combination. When winning an AT lottery (so-called pure lose, etc.), the stoppage at that time always corresponds to one of the AT lottery patterns shown in FIGS. If not, it can be considered that the winning role has been tampered with.

  In the left reel 40a, as shown by the symbol a in FIG. 8, the stop stage is the first seven in the upper stage, the second bell in the middle stage, and the third replay in the lower stage, or the reference numeral l in FIG. As shown, any one of the No. 3 replay, No. 4 bell, and No. 5 watermelon stops in the upper stage. In the AT lottery role, the left reel 40a must come in either the sign a or the sign l, and there is no other case.

  When the left reel 40a has a stop turn of symbol a, the middle reel 40b has a stop turn shown by reference symbol b (second replay, third bell, fourth bell) or stop shown by reference symbol c. It will be one of the numbers (3rd bell, 4th bell, 5th watermelon). For example, when the middle reel 40b has a stop turn of the symbol b, the stop turn of the right reel 40c is any one of the four signs d to g shown in FIG. Similarly, when the number is c, the stop turn of the right reel 40c is one of the four signs h to k shown in FIG. (In other words, depending on the position where the stop button of the right reel 40c is pressed, one of the four stop points will be displayed).

  The same applies to the case where the left reel 40a has a stop turn of reference numeral 1 (see FIG. 9).

  As can be seen from the above description regarding FIG. 8 and FIG. 9, if the design of each reel is determined, all patterns of the AT lottery combination (or all patterns that cannot become the AT lottery combination) are determined. In the first embodiment, all the patterns (16 patterns in the example of FIG. 7) are stored as a table in the correspondence information storage unit 2b.

  An example of the table is shown in FIG. The figure shows the numbers of symbols for stopping the AT lottery combination (16 patterns in total). In the same figure, the number of the stop symbol which stops at the upper stage in each of the left, middle and right reels (40a to 40c) at the time of winning the AT is shown. For example, “1-2-1” in the upper left of FIG. 10 is “1: Seven” for the symbol that stops on the upper stage of the left reel 40a, and “2: Replay” for the symbol that stops on the upper stage of the middle reel 40b. Yes, the symbol that stops at the upper stage of the right reel 40c is “1: Seven”. “1-2-1” in the upper left of FIG. 10 corresponds to the ab-d pattern in FIG. The stop symbol is represented by the upper number, but this is only an example, and the middle or lower number may be used, or other symbols may be used.

  FIG. 11 shows a flowchart of the consistency determination process when the table as described above is stored in the correspondence information storage unit 2b in advance.

S31: Stop stop information is acquired based on the first sensor 162 and the second sensor 163 (see FIG. 6), and the correspondence information storage unit 2b is searched based on the output information.
S32: As a result of the search, it is determined whether there is a pattern that matches the output information. For example, when the reels 40a to 40c are stopped in the states of a, b, and d in FIG. 8, the stop symbol number is “1-2-1.” Since this is in the upper left of FIG. 10, there is a pattern that matches the above-mentioned outcome information (YES in S32). That is, since the winning combination is consistent with the outcome, an alignment flag is set (S33). On the other hand, when the stop symbol number is “1-2-2”, there is no pattern in the table of FIG. 10 that matches the outcome information (NO in S32). That is, since the winning combination is not consistent with the outcome, the winning combination may have been tampered with and an illegal flag is set.

  When the consistency flag is set, error processing is not performed. When the illegal flag is set (or when the alignment flag is not set), S27 in FIG. 6: error processing is performed.

Example 2
Although the first embodiment has the advantage that the AT lottery can be reliably determined, the actual pattern is very large, the amount of data in the table increases, and it is difficult to implement if there is not enough memory capacity. There is also a drawback that the processing load of the CPU increases.

  Example 2 is an example in which a table with a reduced data amount is used. FIGS. 12A to 12C are examples in which the numbers of stop symbols to be stopped are stored in the upper stage of the left reel 40a and the middle reel 40b. In FIG. 12, since the stop symbol of the right reel 40c is not used, the number of data is a quarter (16 → 4) of the first embodiment. On the other hand, even in the case corresponding to the pattern of FIG. For example, FIG. 12A corresponds to the “AT” lottery and also corresponds to “Bell” (for example, “1-2-2” has a set of bells). FIG. 12B similarly corresponds to “bell” (for example, “3-2-2” is a collection of bells) and “replay”. FIG. 12C similarly corresponds to “bell” and “watermelon”.

  The above fact means that even when the non-AT lottery is falsified, it cannot be detected with a probability of 100%. For example, even if the winning combination is changed to the AT lottery combination when the stop event is “1-2-2” and the winning of the bell is detected, this cannot be detected. However, the method of Example 2 is also sufficiently practical. An unauthorized device is provided between the main board 1 and the sub board 2 and is frequently falsified. Even if the falsification is missed at a certain point, the probability of detecting falsification at the next opportunity is sufficiently high. Eventually, cheating can be detected.

  FIG. 13 shows a flowchart of the consistency determination process when the table as shown in FIG. 12 is stored in the correspondence information storage unit 2b in advance.

S30: Stop stop information is acquired based on the first sensor 162 and the second sensor 163 (see FIG. 6), and the left reel 40a and the middle reel 40b (the pressing order is limited to left → middle → right). When the left side is given priority), the pattern for the second body is extracted.
S31b: The correspondence information storage unit 2b is searched based on the extracted pattern.

S32b: It is determined whether there is a pattern that matches the extracted pattern as a result of the search. For example, when the stop symbol number of each reel 40a, 40b is “1-2”, since it is in FIG. 12A, there is a pattern that matches the extracted pattern (YES in S32b). That is, since it is presumed that the winning combination is consistent with the first appearance (there is an exception as described above), an alignment flag is set (S33). On the other hand, when the stop symbol number is “1-4”, there is no pattern that matches the extracted pattern in the table of FIG. 12 (NO in S32). In other words, since the winning combination is not consistent with the outcome (no exception), the winning combination may have been tampered with and an illegal flag is set.

  When the consistency flag is set, error processing is not performed. When the illegal flag is set (or when the alignment flag is not set), S27 in FIG. 6: error processing is performed.

Example 3
Example 3 uses a stop symbol of one of the three spinning cylinders (the first spinning cylinder when the pressing order is set). The third embodiment has the smallest amount of data in the table, but the exception is the largest.

  FIGS. 14A and 14B are examples in which the number of the stop symbol that stops at the upper stage of the left reel 40a is stored. In FIG. 14, since the stop symbols for the middle reel and the right reel are not used, the number of data is half that of the second embodiment (4 → 2). However, FIG. 14A corresponds to the AT lottery and also corresponds to “Bell”, “Seven”, and “Replay”. FIG. 14B similarly corresponds to “bell”, “replay”, and “watermelon”.

  The processing procedure is the same as in the second embodiment.

  In the above description, stop outcomes that are consistent with the correspondence information storage unit 2b are stored. However, the present invention is not limited to this, and stop outcomes that do not match may be stored. In this case, when the stop information pattern received by the sub-board 2 is found in the correspondence information storage unit 2b, it is determined that they are not matched.

  Comparing Example 1 to Example 3, it is considered that Example 2 is preferable from the viewpoint of reducing the amount of data in the table and the certainty of falsification detection. The embodiment 1 is preferable if the memory capacity is sufficient, and the embodiment 3 is preferable if the certainty of alteration detection is not necessarily high.

  In the embodiment of the present invention, the reel stop event information is directly input to the sub-board 2. As a method of detecting the stop line without passing through the main board 1 in this way, a method of detecting a rotation angle by providing a rotary encoder on the rotation shaft of the motor 155 can be considered. However, this method increases the size of the motor and is difficult to install due to its structure.

  Therefore, in the embodiment of the present invention, as shown in FIG. 4A and FIG. 15, the first sensor 162 and the second sensor 163 that are reel position sensors for detecting the stop output of each reel 40, and these (Index 164 for the first sensor 162 is shared with the conventional shielding plate 160 for the photo interrupter 159 as shown in FIG. 4A). May be) The first sensor 162 detects the index once per reel rotation, and the second sensor 163 indexes only the number of symbols per rotation of the reel (FIG. 15 shows the case of 8 symbols for simplicity). Is detected.

  When the reel 40 rotates, a sensor output as shown in FIG. 16 is obtained. 16A and 16B are timing charts in which the horizontal axis represents time and the vertical axis represents voltage level. FIG. 16A shows a sensor output waveform in one rotation when the reel 40 is rotating at a substantially constant speed. FIG. 16B shows a sensor output waveform when the stop button 50 is pressed and the reel 40 stops. This figure shows that the symbol No. 2 is stopped in a state where the symbol is displayed. At this time, the reel 40 has a symbol No. 2 in symbol.

  In order to obtain the symbol number, a counter 165 is provided, the counter 165 is incremented by the second sensor 163, and the counter 165 is reset by the first sensor 163. Since the output of the counter 165 is the symbol number of FIG. 16, this output is sent to the sub-board 2.

  Alternatively, the symbol number may be acquired by the CPU of the sub-board 2. In the sub-board 2, the symbol number is set to 0 each time the first sensor 162 detects the index 164, and the symbol number is incremented by 1 each time the second sensor 163 outputs. The stop position of the reel 40 can be detected by the sub-board 2 using the outputs of these two sensors 162 and 163.

  As shown in FIG. 16B, for example, when the reel 40 is stopped in a state where the symbol number is 2, the consistency determining unit 2a makes a determination based on the symbol number. Specifically, after receiving the winning combination in FIG. 6, the symbol number when the reel stops is acquired, and this is used as stop event information.
