  Conventionally, in a gaming machine such as a pachislot machine or a pachinko machine, there are a plurality of types of “general gaming state” that is a basic gaming state and a plurality of types that are advantageous to a player based on satisfying a predetermined condition or a lottery result. A “special game state” is set, and an effect using a decorative lamp, a liquid crystal display device, a sound generation device, or the like is executed in accordance with these various game states.

  In order to realize the determination of each game state and the execution of the effects, a game machine is mainly sent from the main control circuit board that controls the setting of the game state and the game processing operation, and the main control circuit board. A sub-control circuit board for realizing an effect by light, video or audio based on the control signal is mounted.

  For example, on the main control circuit board of the pachi-slot machine, a medal sensor that detects that a game medium has been inserted by the player, a bet switch that sets an effective line that determines the success or failure of a combination, a start switch that rotates a reel, Stop switch for stopping the rotation of the reel, other input means, a stored number indicator for displaying the number of credited medals, an accessory count indicator, a payout number indicator, a winning indicator, other output means, a reel The reel motor drive circuit that displays the variation of the symbol by performing the rotation control, the medal discharge device for controlling the payout of the game medium and other peripheral devices, and the sub control circuit board are connected. The main control circuit board performs processing based on information input from each input means, and performs game progress, symbol stop display, game medium payout, control of various output means, and the like.

  In such a pachislot machine, as shown in FIG. 30, the main control circuit board 71 is provided in the case 72 of the pachislot machine, and the sub control circuit board 73 is provided on the back side of the front door 74. Further, signals from the bet switch 74, the start switch 75, the stop switch 76, the medal sensor 77, and the like are output to the main control circuit board 71 via a door relay board 78 provided on the back side of the front door 74.

  In addition, an external concentration terminal board 79 is installed inside the housing 72. As shown in FIG. 31, the external concentration terminal board 79 receives signals such as the number of medals inserted / withdrawn from the main control circuit board 71, the number of games, and bonus winning information via an input terminal 79a. . These inputted signals are outputted from the output terminal 79b to the hall computer 80 in the game hall.

  In such a conventional pachislot machine, the main control circuit board 71 and the external concentrated terminal board 79 installed in the casing 72, the sub control circuit board 73 and the door relay board 78 installed in the front door 74, and the game The hall computer 80 in the field is electrically connected by an electric cable 81 in which a large number of wirings are bundled, and transmits and receives necessary signals.

  By the way, in such a gaming machine, when a fraudulent act such as adding an improper signal to the electric cable 91 or causing malfunction due to electromagnetic waves is performed from the gap of the front door 74 or an illegally opened door. There is.

  For this reason, in conventional gaming machines, if an abnormality such as unauthorized opening of the front door or insertion of a foreign object is detected, an alarm is issued or the open / closed state of the front door is monitored by a hall computer. A measure for preventing it has been proposed (see, for example, Patent Document 1).

  In addition, in a gaming machine that performs communication between various boards using the electrical cable as described above, when a problem such as disconnection occurs in a signal line that performs various communications, which signal line is disconnected, that is, It is necessary to be able to easily confirm whether it is in a non-communication state from the viewpoint of maintenance or the like. Therefore, conventionally, an LED module for confirming communication is provided on the surface of an effect control board that controls the effect according to the gaming state, and the LED module is configured so that it can be visually confirmed from the outside (for example, , See Patent Document 2).

  This LED module has a plurality of LEDs corresponding to various signals, and it is possible to confirm that communication is being performed through each signal line by lighting or blinking each LED. On the other hand, if any of these LEDs continues to be extinguished, there is a possibility that some problem, such as disconnection, has occurred in the signal line corresponding to the unlit LED. I can confirm that.

  However, in the gaming machine using the electric cable for the connection between the above-described conventional boards, the opening / closing state of the front door and the presence / absence of foreign matter insertion are monitored, and if an abnormality is detected, an illegal action is performed. Measures are taken to prevent illegal acts on electrical cables when the game hall is at a standstill, when foreign object insertion cannot be detected, or when the front door opening / closing signal is illegal. It was difficult to prevent completely.

  In addition, the external concentration terminal board in the gaming machine has a function of transmitting a signal to the outside of the hall computer or the like when a main signal in the gaming machine is input, thereby monitoring and managing the gaming state of each gaming machine. Although it plays an important role in hall operation, it is fraudulent to the electric cable such as the external concentration terminal board, for example, it seems that the number of games acquired is small, illegal jackpots are generated, the number of jackpots is small When a fraudulent act (got act) that pretends to be performed, it is difficult to monitor and manage the gaming state of each gaming machine, which may cause a serious hindrance to the operation of the hall.

  In addition, the conventional signal transmission / reception means using an electric cable is not limited to the illegal acts as described above, and static electricity is charged to the clothes of the player, and the static electricity is discharged to the gaming machine at the moment when the player touches the gaming machine. In some cases, an electromagnetic current emitted from a mobile phone carried by a player may cause an unexpected current to flow through the electric cable, leading to a malfunction of the control circuit.

  Also, since the electrical cable is a heating element, if a large number of electrical cables are used, the temperature inside the gaming machine will rise, adversely affecting each control board and electrical connection parts, and in turn, generating false signals, disconnecting and connecting cables. There was also the possibility of inducing defects.

  Furthermore, when the gaming machine is electrically connected to an external device such as a hall computer or a data display device using an electric cable, there is room for improper acts such as interposing an illegal board on the electric cable. Therefore, there was a risk of harming the fairness of the gaming machine.

  Further, in a gaming machine in which an LED module for communication confirmation is provided on the effect control board, an improvement for attaching the LED module to the board is necessary. Furthermore, since the gaming machine is provided with a plurality of different types of boards, an LED module must be attached to each of these boards.

A ball passage switch 18 for detecting a sphere, a board surface discharge ball passage 14, and a downstream passage 19 communicating therewith are provided.

  In FIG. 8, the flow of the sphere is as follows.

  That is, (1) the sphere in the upstream passage 13 flows to the ball feeding device 12. (2) The sphere that has flowed to the ball feeding device 12 is sent to the launching device 1 by the operation of the ball feeding solenoid 12M. (3) The sphere sent to the launching device 1 is launched to the board surface through the launching ball detection switch 15 by the operation of the launching solenoid 1M. (4) The out ball or winning ball that has fallen into the board discharge ball passage 14 flows from A to B through the downstream passage 19. (5) The ball that has flowed to B is guided to the screw lower end position C of the ball transport device 17 and is raised to the screw upper end position D by the operation of the ball transport motor 17M. (6) The ball that has risen to D returns from E to the upstream passage 13. (7) A return ball that does not reach the board surface passes through the return ball detection switch 16, passes from F to G, merges with the board surface discharge ball, and flows to B.

  If the ball passage switch 18 cannot detect a ball for a certain period of time, it is considered that a ball is clogged in the circulation path, and an error state occurs. The ball feeding device 12 and the launching device 1 are driven by the turning operation of the launching handle 10, and when the launching ball detection switch 15 detects the launching ball and the return ball detection switch 16 does not detect the return ball, the credit frequency Is counted down (see steps 014 to 019 in FIG. 11).

The game balls that flow down on the rails 48 are guided to the discharge device 5. The reason why each of the sphere suction ports 47 has a partition structure that allows only one sphere to pass is to prevent a go-to action such as insertion of an illegal sphere.

  As shown in FIG. 10, the same rotary ball delivery device 8 as that used in the dispensing device 3 is employed for the discharging device 5. The guide body 810 connected to the game ball take-in port 81 is fitted into the lower end claw 49 of the guide rail 48. In the ball delivery device 8 used for the discharge device 5, the outlet of the discharge port 83 is opened to the island 300 as it is. In addition, the game ball staying upstream of the discharge port 83 can be returned from the return port 84 by reversing the rotary disk 82, and the outlet 870 of the return passage 87 extending from the return port 84 is connected to the ball outlet 41. It is arranged adjacent to the lower passage 45 near the lower part.

  A guide rod 421 is provided integrally with the ball removal slider 42. The ball removal slider 42 is urged in the closing direction by a spring 422 that receives a guide bar 421 at one end.

  The credit-up operation by forward rotation of the discharge device 5 shown in FIG. 10 is as follows.

  That is, (1) When a game ball is thrown into the tray 4, the game ball flows down to the suction port 47 due to the gradient of the tray 4. (2) After the game ball passes through the suction port 47, it reaches the intake port 81 through the guide rail 48. (3) The game ball is stored in the groove 820 of the rotating disk 82 or above. (4) When performing credit-up by counting the number of game balls, a current is supplied to the motor 821 so that the rotating disk 82 rotates counterclockwise (forward rotation). (5) The game ball that has entered the groove 820 of the rotating disk 82 moves along with the rotation of the disk 82 and passes through an upper portion of an upstream detection switch (not shown). (When the predetermined number of game balls is counted by the upstream detection switch, the motor 821 is stopped.) (6) The game ball that has passed through the upstream detection switch falls to the island 300. In the middle, a downstream detection switch (not shown) is provided, and the number of game balls counted by these two switches is credited.

  As shown in FIG. 9, the return of the remaining sphere and the sphere on the guide rail 48 due to the reverse rotation of the discharge device 5 is as follows.

(2) A current is supplied to the motor 821 so that the ball removal detection switch 46 is actuated by the rotation of the crank 44 and the rotating disk 82 rotates rightward (reversely). (3) The game ball that has entered the groove 820 of the rotating disk 82 moves along with the rotation of the disk 82 and falls from the return port 84 to the return passage 87. (4) The game balls flow down due to the gradient of the return passage 87, join the lower passage 45 connected to the lower side (dollar box) of the tray 4 and are returned.

  As described above, the ball return to the dollar box can be arbitrarily performed when the number of balls stored in the tray 4 increases (step 023 in FIG. 11), and after the game is finished, the settlement button 140 is pressed to pay out the credit to the tray 4. By subsequently performing, all the balls of the tray 4 can be collected at hand (steps 024 to 027). In addition, after paying out the credit amount to the tray 4 and resuming the game, the game is moved to the island 300 side by pressing the automatic supply button 150 or the manual supply button 160 without operating the ball pulling operation tool 40.

  By the way, in a general pachinko gaming machine, by adjusting the nail on the game board surface, it is possible to easily adjust the case where the game ball is likely to go to the start winning opening and the case where it is not. For this reason, the winning rate of the entire pachinko gaming machine differs for each pachinko gaming machine depending on the degree of nail adjustment. Therefore, there is a problem that the winning rate varies depending on the skill or skill level of the player.

  Therefore, the pachinko gaming machine according to the present embodiment has a function of making the probability of opening the electric tulip 23 of the start winning opening 22 variable according to the number of shot balls. In other words, the pachinko gaming machine according to the present embodiment has a high probability of opening the electric tulip at the start winning opening 22 when the number of winning balls at the start winning opening 22 is small relative to the number of shot balls, and can be started easily. It can be said that it has a kind of correction function that corrects the winning rate by enabling winning. Thereby, the nail adjustment by a special skill is not required, and the result according to the scheduled winning rate can be generated without being greatly influenced by the skill of the player in the actual game.

  Here, the effect of the correction function will be described below. In other words, the winning rate can be arbitrarily finely set on the game venue operator side, and the setting of the winning rate can be freely changed based on the business target or the like. Further, since the winning rate can be controlled, the technical intervention can be reduced, and the game can be enjoyed regardless of the skill of the player. Furthermore, excessive technical intervention by skilled players with high skills can be reduced. In addition, since nail adjustment is not necessary, it contributes to the reduction of the nail adjustment work burden on the amusement hall, which in turn leads to a reduction in the labor cost of the amusement hall and the work burden. In addition, failure due to nail adjustment can be prevented, leading to reduction in repair costs due to failure and replacement costs of new gaming machines, and prevention of a decrease in operating rate of gaming machines due to failure.

  Next, the configuration and operation related to the above correction function will be described.

  As shown in FIG. 15, the launching device 1 has a structure in which a plunger type solenoid is excited to launch a game ball, but a structure using a rotary solenoid or a motor as a drive source may be used. A first ball detection switch 15a and a second ball detection switch 15b are provided as the ball detection means for detecting a game ball shot from the launch device 1. Here, the first launch ball detection switch 15a is a launch ball detection switch close to the launch device 1 among the launch ball detection switches 15 shown in FIG. 8, and the second launch ball detection switch 15b is shown in FIG. Among the launch ball detection switches 15, the launch ball detection switch is provided on the downstream side in the launch direction with respect to the first launch ball detection switch 15a. These two launch ball detection switches are used to determine whether or not the game ball has been reliably fired. A drive signal is output to the launch device 1, and the first launch ball detection switch 15a outputs a detection signal. Thereafter, it is determined that the game ball has been fired for the first time after the second fire ball detection switch 15b detects the detection output. Therefore, if the second shot ball detection switch 15b first outputs a detection signal and then the first shot ball detection switch 15a outputs a detection signal, an error occurs and the game ball is not shot. .

  In addition, a return ball detection switch is used to detect a return ball that does not reach the game area even if the game ball passes through the first shot ball detection switch 15a and the second shot ball detection switch 15b in order. 16 is provided.

  Further, as an electrical configuration related to the correction function described above, as shown in FIG. 12, the main control circuit board 60 includes a first launch ball detection switch 15a, a second launch ball detection switch 15b, and a return ball detection switch 16. It is connected. Further, a setting switching device 90 is connected to the main control circuit board 60. The setting changeover device 90 includes a setting key switch and a setting changeover switch (not shown). The setting key switch determines whether or not the setting key inserted into the keyhole is a genuine one and inserts it. The setting changeover switch is switched by rotating the set key in a predetermined direction. By switching the setting changeover switch, it is possible to switch the winning probability table storing the probability of occurrence of various winnings. Although not shown in the present embodiment, the main control circuit board 60 is connected to a random number generator that generates random numbers used in the progress of each game.

  When the power switch is turned on, the main control circuit board 60 performs initialization processing of the memory and registers, and when an interrupt signal (reset pulse) is generated, interrupt processing such as update processing of random numbers used in game control is performed. Run sequentially.

  Hereinafter, with reference to FIG. 16, a game processing procedure by the main control circuit board 60 will be described.

  As shown in FIG. 16, first, a probability that a random value generated in accordance with a shot ball becomes a predetermined value (hereinafter referred to as a predetermined value probability) is determined (step 201). The predetermined value probability is determined by whether or not the “specific condition” is established during the game. Here, the specific condition is, for example, the probability that the variable symbol display on the normal symbol display device 29 stops in a specific manner (stop probability). ) Is established if the gaming state is high, and is not established if the gaming state has a low stop probability. That is, it is determined whether or not the stop probability is high, and the predetermined value probability is determined by selecting the predetermined value probability from a plurality of preset probabilities according to the result.

  Next, it is determined whether or not there is a firing ball (step 202). Here, when there is a detection output from both the first launch ball detection switch 15a and the second launch ball detection switch 15b in accordance with the game ball launched from the launching device 1 by the player's operation, it is determined that there is a launch ball. Is done. At this time, first random number extraction is performed (step 203). That is, one random number value is extracted from the random number generator at a predetermined timing. The random number extraction timing may be when there is a detection output from the two shot ball detection switches or after a certain time has elapsed. Then, it is determined whether or not the extracted random number value is a predetermined value (win) (step 204). When “YES” (win), a winning condition counter as a counting means is incremented by “+1” (step 205). ), "NO" (out of), the winning condition counter does not change.

  Here, the function of the winning condition counter will be described. In order to adjust the winning probability that is not influenced by the skill of the player as described above, in the case of winning, as a result of random number extraction by the timing of game ball firing, for example, It is conceivable to give a privilege of opening the start winning opening 22. However, not only in pachinko machines, but in ball game machines, it can be said that a game was actually played only after the released game ball contacted any member provided in the game area. The above-mentioned privilege giving method is strange in the light of the basic game in which profits can be obtained according to the skill of the player, which may result in distrust to the player.

  Therefore, if the result of the random number determination is successful, the result is accumulated in the counter, and the start winning opening 22 is opened on condition that the game ball has actually passed through the passing gate 25 provided in the game area. The normal symbol which is a condition for performing is variably displayed, the probability that it becomes a specific mode is changed according to the count value of the counter, and the opening of the start winning opening 22 is controlled based on the stop probability. If this is the case, the player will not have such distrust. For this reason, when the result of the first random number lottery with the shot ball is a win, the result is stored (“+1”).

  In this embodiment, the winning condition counter is incremented by “1” every time the random number lottery is won, but “2” may be incremented every time the random number is won, or conversely, it is won twice. You may make it add "1" every time. Further, instead of simply performing random number lottery, “1” may be added when a shot ball is detected.

  Next, some of the launch balls have passed through the above two launch ball detection switches, but some of them return without reaching the game area due to weak resilience. It is detected by the sphere detection switch 16. Accordingly, in the process of FIG. 16, it is determined whether or not there is a return ball (step 206). If there is a return ball, random numbers are extracted for the game ball to be fired next time. The random number extraction is stopped (step 207). It should be noted that the current random number lottery may be performed when there is no return ball even after a predetermined time has elapsed after detection of the shot ball by the two shot ball detection switches.

  When the game ball launched into the game area passes through the pass gate 25 and passes through the pass gate switch 25a (step 208), the normal symbol display device 29 starts to operate (step 209), and the pass gate switch 25a. The second random number is extracted from the random number generator at the timing when the game ball is detected (step 210). This random number extraction may be performed before the normal symbol display device 29 is activated.

  Next, it is determined whether or not the value of the winning condition counter is larger than a predetermined value (step 211). This predetermined value is, for example, the center value of the counting range of the counter to be used. If the result of the determination is greater than a predetermined value, winning probability data specifying the generation range of random numbers and the numerical value to win is selected so that the probability that the winning symbol stops on the normal symbol display device 29 is high ( Step 212) If the determination result is equal to or less than a predetermined value, the winning probability data is set to a low probability (Step 213).

  The winning probability data determined in this way is compared with the value of the second random number (step 214), and if the result is a win, the winning symbol is stopped and displayed on the normal symbol display device 29 (step 214). 215) In the case of detachment, the detachment symbol is stopped and displayed (step 216).

  As described above, the probability that the random number value by the shot ball becomes a predetermined value and the probability that the normal symbol display device 29 that makes the start winning opening 22 open will be in a specific mode based on the predetermined condition. By changing the selection, the probability of winning in the start winning opening 22 is adjusted.

  When the winning symbol is stopped and displayed, the start winning opening 22 is opened for a certain period of time in the sense of giving a privilege to the player (step 217). When a game ball wins the established start winning opening 22 and the start opening switch b1 outputs a detection signal (step 218), the winning condition counter is decremented by "1" (step 219). This subtraction is the same as adding “−1” in the calculation process.

  Here, “+1” (addition) as described above results in the condition for opening the start winning opening 22 being established, but conversely, “1” subtraction is the start winning opening. It will move away from the achievement of the condition of opening 22. In the above description, when one game ball is won at the start winning opening 22, the winning condition counter is decremented by “1”, but two game balls are won and “1” is subtracted, or one is won and “ 2 ”may be subtracted. Thereafter, when a predetermined time has elapsed (ST220), the start winning opening 22 is closed (step 221). In FIG. 16, the start winning opening 22 is closed when a certain time has elapsed. However, when there is a winning ball at the starting winning opening 22, the start winning opening 22 is closed even before a certain time has elapsed. It can be activated.

  In the game control process including the conversion of the start winning opening 22 and other operations as described above, whether or not the random number lottery for determining the predetermined value probability and the stop probability corresponds to a specific value. That is to say, if the random lottery is always performed in the same range or the same specific value, the result of the lottery is predicted by the player, and the purpose of the game control based on the probability as described above cannot be achieved. Therefore, for example, each time an interrupt signal is generated, the random number lottery can be made more effective by changing the value to a value obtained by adding a certain value (for example, +1) to the previous specific value (for example, a random value that is “winning”), that is, updating. It can be a typical one.

  FIG. 17 shows various random number update processes performed based on the above-described idea in the pachinko gaming machine according to the present embodiment.

  As shown in FIG. 17, first, a random number for determining the big hit that determines whether or not the variable display of the special symbol display device 28 is stopped in a specific manner (big hit) is updated within a certain range (step 301). ). This random number is extracted when a game ball wins the start winning opening 22.

  Next, it is determined whether or not the current gaming state is a high probability state (step 302). This determination is made based on whether or not a flag indicating a specific condition (high probability state) is set (set) at an address designated in the main RAM 63 of the main control circuit board 60. This flag is set to be set when the count value of the winning condition counter exceeds a predetermined value. As described above, this counter increments (+1) every time the random number generated in response to the detection of the fired ball is a predetermined value, and subtracts (-1) every time the starting winning ball is detected. When the count value exceeds a predetermined value, the flag is set (high probability state), and when the count value does not exceed the predetermined value, the set is released (low probability state).

  In the case of the low probability state (flag set release) in the above determination (step 302), random numbers extracted according to the six types of fired balls set in the winning probability table storing various winning occurrence probabilities are predetermined. From the probability data as values, it is confirmed which setting switching device 90 designates (step 303).

  After the confirmation, data in the designated random range for low probability is selected (step 304). This low-probability random number range data is data set to lower the probability that the random number extracted according to the launch ball will be a predetermined value by widening the random number update range, There are differences for each of the six types of probability values set.

  On the other hand, in the case of a high probability state (flag set) in the determination in step 302, data set so as to increase the hit probability of the shot ball by narrowing the range of random number update is selected (step 305). ). As described above, the random number update is continued within the random number update range (step 306).

  The probability can be adjusted by changing the random number update range as described above. Furthermore, the probability value set in the winning probability table is represented by “number of random numbers per random number / random number update range”. Since the numerator is smaller than the normal denominator, the random number update range of the denominator can be changed to change the probability value. It is possible to finely adjust the probability.

  Next, the determination random number is updated to determine whether or not to stop the normal symbol in a specific manner. That is, the random number is updated within a predetermined range of random numbers generated when the game ball passes through the passing gate 25 (step 307).

  In addition, as a production effect until the special symbol is stopped in the case of “big hit”, the random number is updated within a predetermined range of random numbers that causes a stopping process different from the special symbol stopping process in the normal time (step) 308), the random number is updated within a predetermined range of the random number corresponding to the special symbol displayed at the time of stopping in the case of big hit (step 309).

  Further, the random number is updated within a predetermined range of the random number corresponding to the normal symbol displayed at the time of stopping in the case of winning (step 310), and the random number corresponding to the normal symbol displayed at the time of stopping in the case of a loss The random number is updated within the predetermined range (step 311).

  This completes one random number update process and repeats the above procedure. Meanwhile, random numbers are extracted from the corresponding random number update process by the generation of a predetermined detection signal.

  As shown in FIG. 16 and FIG. 17, the winning rate is adjusted by controlling the operation of the start winning opening 22, and the relationship between the winning condition counter and the probability that the normal symbol stops in a specific manner is shown in FIG. This will be explained based on.

  FIG. 18 shows the transition of switching between two types of probability data in which the normal symbol stop probability corresponding to the transition of the winning condition counter value is set.

  The winning condition counter is an 8-bit counter and can take an area of “0 to 255”, and “128” is set as an initial value when the power is turned on or a big hit occurs.

  Here, in the case of winning in step 204 of FIG. 16, the value of the winning condition counter is incremented by “1” from the initial value “128” to become “129”. At this time, the probability data is switched from a low probability to a high probability. The specific probability value is set as a winning probability table and stored in the storage unit of the main control circuit board 60. When the value of the winning condition counter becomes “128” or less, the probability data is switched to low probability data again.

  FIG. 19 shows the transition of the number of difference balls when the pachinko gaming machine plays a game as described above. In the figure, the solid line portion represents a desired expected value, and the broken line portion represents a result according to the embodiment of the present invention.

  As illustrated, according to the embodiment, a locus close to an expected value can be drawn. The reason for this is that when low probability data is set, the winning condition counter value is low, that is, when the number of hits is small in the random number determination by the shot ball, so the display mode when the normal symbol display device 29 is stopped Becomes a winning and the start winning opening 22 is less likely to be opened. Therefore, the negative difference will increase. In FIG. 19, a locus starts to be drawn in a direction away from the expected value.

  However, since the random number determination by the launch ball is performed based on the probability, there is always an opportunity for the random number determination to be a hit, the value of the winning condition counter is increased, and high probability winning probability data is set. become. At this time, contrary to the case where low probability winning probability data is set, the number of difference balls moves in the positive direction. Start drawing a trajectory where this movement changes in a direction that approaches the expected value.

  Therefore, when these two operations are combined, a locus shown by a broken line is obtained. Further, since one hit of the ball and one winning to the start winning opening 22 are equivalently offset, the probability of being used for random number extraction of the ball is consequently obtained. The number of difference balls is controlled to be along.

  Next, characteristic parts of the pachinko gaming machine according to the present embodiment will be described with reference to FIGS. 12 and 20 to 23.

  As shown in FIG. 12, a main control circuit board 60, a sub control circuit board 400, a payout board 192, an external terminal board 500, a hall computer 501, a data display 502, a CR unit 200 and other peripherals constituting the pachinko gaming machine The devices are connected to each other by a communication cable in order to input and output necessary information. In a conventional pachinko machine, an electric cable is used as a communication cable.

  In the present embodiment, among the communication cables described above, in particular, between the main control circuit board 60 and the external terminal board 500, between the external terminal board 500 and the hall computer 501, and between the external terminal board 500 and the data display 502. A single-core optical fiber cable 901 is used as a communication cable used between the two. Each optical fiber cable 901 can communicate in only one direction. In addition, the hall computer 501 and the data display 502 in the present embodiment constitute an external device according to the present invention.

  The optical fiber cable 901 has a high degree of security and high safety against unauthorized electromagnetic or mechanical means from the outside. In other words, with conventional electrical cables, it has been difficult to prevent fraudulent acts such as electromagnetic wave or electric signal application, or unauthorized replacement such as rewiring, but optical fiber cables must prevent such fraudulent acts. Is possible.

  Specifically, the output terminal 60 b of the main control circuit board 60 and the input terminal 500 a of the external terminal board 500 are connected by an optical cable unit 900 having an optical fiber cable 901 and connectors 902 and 903. Similarly, the optical cable unit 900 is provided between the output terminal 500b of the external terminal board 500 and the input terminal 501a of the hall computer 501, and between the output terminal 500c of the external terminal board 500 and the input terminal 502a of the data display 502. Connected with.

  The connector 902 includes therein an electrical / optical signal converter (not shown) that converts electrical signals output from the output terminals 60b, 500b, and 500c of each device into optical signals and transmits them to the optical fiber cable 901. Have. The connector 903 includes an optical / electrical signal converter that converts an optical signal transmitted through the optical fiber cable 901 into an electric signal and inputs the electric signal to each input terminal 500a, 501a, 502a of each device. . For this reason, in this embodiment, modules such as an electric / optical signal converter and an optical / electrical signal converter are incorporated in all of the main control circuit board 60, the external terminal board 500, the hall computer 501, and the data display 502. There is no need. In other words, by using only the optical cable unit 900 according to the present embodiment, it is possible to use a device having an existing configuration in which a module such as an electrical / optical signal converter or an optical / electrical signal converter is not incorporated. . Therefore, since it is not necessary to separately install a dedicated module in each device in order to perform optical communication between the devices, it is possible to connect the devices by optical communication with an inexpensive and simple configuration.

  By the way, even when a plurality of optical fiber cables 901 are used as communication cables, which of the optical fiber cables 901 is disconnected when a failure such as disconnection occurs in any of these optical fiber cables 901, In other words, it is necessary to be able to easily check whether the communication state is not in view of maintenance or the like. Therefore, in the present embodiment, the optical cable unit 900 is configured as follows in consideration of this point.

  As shown in FIG. 21, the optical cable unit 900 includes an optical fiber cable 901, a transmission-side connector 902, and a reception-side connector 903.

  As illustrated in FIGS. 22A and 22B, the optical fiber cable 901 includes an optical fiber 910 including a core 911 and a clad 912, and a coating 920 that covers the optical fiber 910.

  The core 911 is made of, for example, polymethyl methacrylate resin. The clad 912 is made of, for example, a fluororesin. Therefore, the optical fiber 910 is a so-called plastic optical fiber, and has superior characteristics in terms of molding processability, weight reduction of members, cost reduction, flexibility, impact resistance, etc., compared to a quartz optical fiber. Have. For example, a plastic optical fiber is not suitable for long-distance optical transmission because of a large optical transmission loss compared to a silica-based optical fiber. Such a so-called large diameter can be achieved. This increase in the diameter eliminates the need to increase the connection accuracy of various peripheral parts and devices used for branching and connection of the optical fiber with the optical fiber. Therefore, the plastic optical fiber has the merit that connection with peripheral parts and devices, ease of terminal processing, and high-precision alignment are unnecessary.

  In addition, the clad 912 according to the present embodiment has a scattering structure in which visible light as communication light transmitted through the core 911 is scattered inside and emitted from the outer peripheral surface to the outside. The scattering structure is a structure in which the material constituting the clad 912 exhibits refractive index fluctuation, particularly density fluctuation. That is, it means a state in which the refractive index is partially different, and in particular has a non-uniform structure with different densities. One example is a structure in which irregularities and the like are formed on the outer surface of the clad 912. That is, the cladding 912 is roughened on at least a part of its outer surface. Therefore, most of the visible light as communication light is transmitted while being totally reflected in the core 911, but the remaining part depends on the wavelength of visible light and the incident angle with respect to the irregular surface of the outer surface of the cladding 912. Diffusely reflected or transmitted to the outside. Thereby, a part of visible light transmitted to the outside can be visually recognized, and the communication state can be visually confirmed with a part of the visible light. In addition, not only the outer surface of the clad 912 but also the inner surface of the clad 912 or the interface between the clad 912 and the core 911 may be roughened.

  The coating 920 is made of a transparent plastic resin or the like so that the optical fiber 910 can be viewed from the outside. For this reason, a part of visible light emitted outside from the clad 912 as described above can be visually recognized.

  Further, the outer surface of the coating 920 is subjected to a mirror finish that reflects external light. Here, the mirror finish is a process such as attaching a film such as a half mirror that reflects part of light and transmits part of light to the outer surface. Thereby, even if it is a case where the communication light which transmits the inside of the optical fiber 910 is made into the structure which can be visually observed, the influence of the external light with respect to the communication light can be excluded. Accordingly, it is possible to prevent fraud such as a command goto performed for communication light.

  As shown in FIG. 21, the transmission-side connector 902 is made of a transparent plastic resin or the like so that the inside can be seen through.

  As shown in FIG. 23, the transmission-side connector 902 includes a first light source 902a for communication, a second light source 902b for visualization, a dichroic mirror 902c, and a condensing lens 902d.

  As the first light source 902a for communication, for example, a semiconductor laser such as VCSEL (Vertical Cavity Surface Emitting LASER) or LD (Laser Diode) can be used. Further, as the second light source 902b for visualization, for example, a semiconductor laser such as a red LED can be used.

  The communication light emitted from the first light source 902a passes through the dichroic mirror 902c, and the visualization light emitted from the second light source 902b is reflected by the dichroic mirror 902c, thereby visualizing the communication light. The light for use is superimposed. This light beam is condensed by the condensing lens 902d, is incident on the core 911 from one end face of the optical fiber 910, and becomes the communication light described above. Therefore, the visible light as the communication light described above is strictly composed of a light beam in which communication light and visualization light are superimposed, and in particular, light visible from the outside is emitted from the second light source 902b. Is the visualization light.

  In the present embodiment, communication light and visualization light are overlapped to form communication light. However, the present invention is not limited to this, and light itself emitted from the first light source 902a may be visible light. In this case, the second light source 902b is not necessary.

  The connector 903 on the receiving side receives light from the first light source 902a emitted from the other end face of the optical fiber 910 and converts the electric signal from the light receiving element 903a into data. And a demodulating circuit 903b for outputting. Further, in the present embodiment, a filter 903c that selectively transmits only the light from the first light source 902a out of the light emitted from the other end surface of the optical fiber 910 may be provided in the connector 903 on the receiving side.

  As described above, the pachinko gaming machine according to the present embodiment can transmit information with high communication speed and high reliability by using the optical cable unit 900, and the influence of external noise due to static electricity or the like. Therefore, malfunctions of the main control circuit board 60 and the like can be reduced. Furthermore, it is possible to reduce the occurrence rate of failures such as substrate failure due to heat dissipation, wire breakage or connection failure.

  Further, the pachinko gaming machine according to the present embodiment includes an optical cable unit 900 that connects between the main control circuit board 60 and the external terminal board 500, and between the external terminal board 500, the hall computer 501, and the data display 502. Since the communication state is configured to be visible, the communication state between the devices can be easily grasped without using a special instrument or the like. For this reason, the visualization of the communication state can be realized at low cost only by using the optical cable unit 900. Furthermore, it is possible to remove only the optical cable unit 900 from the pachinko gaming machine and attach it to another pachinko gaming machine, thereby reducing costs by reuse regardless of the type of pachinko gaming machine.

  In addition, since the optical terminal unit 500 is connected between the main control circuit board 60 and the external terminal board 500, and between the external terminal board 500 and the hall computer 501 and the data display 502, it is an illegal board compared to the conventional electric cable. It becomes difficult to intervene, etc., and the fairness of pachinko machines can be maintained.

  In the pachinko gaming machine according to the present embodiment, the communication light transmitted through the optical fiber 910 is visible light, and at least one of the coating 920 and the connectors 902 and 903 is formed of a transparent member. The communication light transmitted through 910 can be made visible.

  In addition, the pachinko gaming machine according to the present embodiment uses communication light transmitted through the optical fiber 910 as visible light, and the coating 920 is formed of a transparent member, and at least part of the outer surface of the cladding 912 is roughened. Therefore, a part of the communication light transmitted through the optical fiber 910 can be intentionally leaked from the portion where the rough surface processing of the clad 912 is performed. Thereby, the communication light transmitted through the optical fiber 910 can be more easily visually confirmed.

  In addition, the pachinko gaming machine according to the present embodiment can comply with strict laws by prohibiting electrical connection between the main control circuit board 60 and external devices. Furthermore, since the output from the main control circuit board 60 is only unidirectional using the optical cable unit 900 and the communication state is visible as described above, the communication state can be checked visually while complying with strict laws. In addition, it is difficult to make modifications related to so-called hanging or the like with an illegal board interposed, and each communication state can be easily grasped even while the pachinko gaming machine is operating. Further, since the connection is made by optical communication, not only the above-described illegal goto (for example, command goto) can be prevented, but also stable communication can be secured. As a result, it is possible to reduce the failure rate due to electrical stabilization and the burden associated with repairs and the like, resulting in cost reduction.

  The pachinko gaming machine according to the present embodiment is an enclosed gaming machine and has a configuration in which the board game ball and the payout game ball are completely separated. For this reason, by using the above-described optical communication and a highly accurate board game ball that does not contain illegal balls or the like, mechanical and electrical problems can be reduced, and pachinko machines in a game hall can be reduced. The need for adjustment and repair can be reduced. Therefore, there is an advantage that not only cost reduction but also inspection and operation management can be easily performed.

  Further, the pachinko gaming machine according to the present embodiment has a winning rate correction function, and the setting switching device 90 can switch the winning probability table, so that a substantial payout rate setting function can be realized. It becomes. This makes it possible to make adjustments by setting the payout rate, thereby eliminating operations that lack fairness, such as strict nail adjustments in which game balls are extremely difficult to win. Further, since the payout rate can be adjusted by setting, it is possible to eliminate the need for nail adjustment. By eliminating the need for nail adjustment, it is possible to provide a game machine similar to that used in the type test to the amusement hall. This leads to strict operation of the type test and fair operation at the amusement hall. Furthermore, since the winning rate can be controlled, the pachinko gaming machine can be operated at the same winning rate as in the type test while reflecting the skill of the player.

  In this embodiment, the optical cable unit 900 connects the main control circuit board 60 and the external terminal board 500, and the external terminal board 500, the hall computer 501, and the data display 502. However, the present invention is not limited to this. Instead, for example, the optical control unit 900 may be connected between the main control circuit board 60 and the sub control circuit board 400, or between the main control circuit board 60 and the payout board 192. In addition, the optical cable unit 900 may be used to connect various devices connected to the main control circuit board 60.

  Further, in the present embodiment, in FIG. 12, the main control circuit board 60 and the CR unit 200 are configured to be capable of bidirectional communication. However, the present invention is not limited to this. There is no need to provide a signal line that goes to. In this case, it is preferable to provide a rental button on the CR unit 200 so that the rental information is transmitted to the main control circuit board 60. Further, in such a configuration, only one-way communication is possible between the CR unit 200 and the main control circuit board 60. Therefore, the optical cable unit 900 in the present embodiment is used as a signal line used here. May be used.

  Further, the optical cable unit 900 may be configured as described below.

  As shown in FIG. 24, in the optical cable unit 900, the receiving-side connector 903 has a photodetector 904. In this example, since the optical cable unit 900 can communicate in only one direction, the photodetector 904 is provided only in the connector 903 on the receiving side.

  The light detector 904 is connected to the light extraction unit 905 that extracts the position of communication light transmitted through the optical fiber 910 and detects a part of the communication light extracted from the light extraction unit 905. The light detection unit 906 and a display unit 907 that displays the detection result of the light detection unit 906 are included.

  The light extraction unit 905 is a hole that penetrates the housing of the connector 903 inside. Thereby, the communication light inside the connector 903 can be taken out. In this case, in the connector 903, the clad 912 is roughened at the end of the optical fiber 910, for example. Also, the coating 920 is configured to be transparent or absent.

  The light detection unit 906 includes a light receiving element such as a photodiode, for example, and receives communication light leaking through the light extraction unit 905. That is, communication light is detected.

  The display unit 907 includes, for example, a light source such as an LED. When communication light is detected by the light detection unit 906, the display unit 907 performs signal processing on the communication light and turns on the LED. Therefore, when communication light is not detected by the light detection unit 906, the LED is not lit.

  With this configuration, in this example, the communication state of communication light transmitted through the optical fiber 910 can be viewed via the display unit 907. In this case, even if the communication light transmitted through the optical fiber 910 is not visible light, the communication state of the communication light can be visually observed.

  Further, as shown in FIG. 25, a configuration may be adopted in which a part of the optical fiber 910 is roughened and a portion where the roughening is performed is covered with a casing 930. Even in this case, the coating 920 is made of a transparent member. In addition, a window portion (not shown) for visually recognizing a roughened portion is provided on the upper portion of the housing 930, that is, a surface closed by a cover 931 described later.

  The casing 930 includes a cover 931 that can be opened and closed, and can open or close the window portion to the outside in accordance with the opening and closing of the cover 931. Thereby, when it is not necessary to visually check the communication state, the influence of external light can be eliminated by closing the cover 931. Moreover, you may make it restrict | limit the opening and closing of this cover 931 as needed. Specifically, the cover 931 can be locked to the housing 930 or configured so that it cannot be opened unless a password or the like is input, so that only those involved in the game hall can open the cover 931. It is. In this case, a configuration may be added that issues an alarm when the locking is released by an unauthorized method. As a result, it is possible to prevent fraud such as a command line.

  As shown in FIG. 26, a cover 940 that can be opened and closed is provided on the connector 903 itself, and a window portion 941 that allows the inside of the connector 903 to be visually recognized is provided at a predetermined upper portion of the connector 903 that is closed by the cover 940. It is good also as a structure. Note that the cover 940 may be formed of a transparent member and may be processed with a half mirror or the like to eliminate the influence of external light. Thereby, command goto can be prevented by eliminating the influence of external light. Also in this case, similarly to the above-described example, the cover 940 can be locked to the connector 903 or can be configured to be opened only when a password or the like is input. In this case, the cover 940 is not necessarily transparent.

  In addition, in the example shown in FIG. 26, only when the communication state is confirmed, a photodetector with a built-in light receiving element is attached to the window portion 941, and the communication state of the optical fiber cable 901 is confirmed by this photodetector. May be. In this case, the communication light transmitted through the optical fiber 910 is not necessarily visible light. Moreover, as a photodetector, the thing similar to the photodetector 904 shown, for example in FIG. 24 can be used.

  As shown in FIG. 27, the optical fiber cable 901 is forcibly bent by the driving device 950, and a part of communication light leaking from the bent portion is detected by the photodetector 960 installed at the bent portion. You may comprise as follows. In this case, the covering 920 is made of a transparent member.

  As the driving device 950, for example, a rack and pinion mechanism, a pulley mechanism, or the like can be used, and a device provided with a motor 951 as a driving source can be used. Further, as the photodetector 960, for example, the same one as the photodetector 904 described in FIG. 24 can be used. The driving device 950 is repeatedly driven every predetermined time. Alternatively, it may be driven in conjunction with the game hall only when the inside of the gaming machine main body 100 is opened. Note that if visible light is used as communication light, the light detector 960 may not be provided and may be confirmed visually.

  Also, as shown in FIG. 28, an optical fiber cable 901 is branched by a branching device 970 in the middle thereof, and a part of the communication light after branching via an optical fiber cable 971 connected to the branching device 970 is used for inspection. You may make it display with the display apparatus 972. The branching device 970 takes out a part of communication light transmitted through the optical fiber cable 901 using, for example, various optical members, or reflects the reflected light and branches it to the optical fiber cable 971. As the branching device 970, for example, various optical members such as a light transmissive waveguide, a half mirror, and an optical waveguide can be used. As the display device 972, a configuration in which a light receiving element such as a photodiode is provided and an LED is turned on in accordance with an electric signal from the light receiving element can be used. Alternatively, the tip portion of the optical fiber cable 971 may be configured to be directly visible from the outside, and the communication light emitted from the tip portion to the outside may be visible.

  In the present embodiment, the first random number is determined when it is determined that there is a fired ball using the detection results of the first fired ball detection switch 15a and the second fired ball detection switch 15b with respect to the above-described winning rate correction function. Although extraction is performed (step 203 in FIG. 16), the present invention is not limited to this. For example, as shown in FIG. 29A, a shot ball is detected immediately before the game ball reaches the board from the guide rail 20. A projecting ball detection switch 980 may be provided, and the first random number extraction may be performed on condition that the projecting ball detection switch 980 detects a projecting ball. More specifically, the firing ball detection switch 980 is upstream in the launching direction (launching device side) with respect to the approach prevention mechanism 981 that prevents the launching ball launched from the guide rail 20 to the board surface from entering the guide rail 20 again. Provided. As a result, it is possible to reliably detect the fired ball actually fired on the board, and it is not necessary to determine the presence or absence of the return ball, so that the correction function described above can be made to work accurately. In this case, steps 206 and 207 in FIG. 16 may be omitted.

  In addition, as shown in FIG. 29B, the firing ball detection switch 980 may be provided on the downstream side in the firing direction from the approach preventing mechanism 981. Even in this case, the same effect can be obtained.

  Further, in the present embodiment, the main control circuit board 60 and external devices such as the hall computer 501 and the data display 502 are connected via the external terminal board 500. An external device such as the hall computer 501 or the data display 502 may be connected to the CR unit 200. In this case, necessary information such as jackpot information is transmitted from the main control circuit board 60 to the CR unit 200 through a communication cable that transmits information to the CR unit 200, and is transmitted from the CR unit 200 to an external device. Also in this case, it goes without saying that the optical cable unit 900 according to the present embodiment may be used for the communication cable that connects the CR unit 200 and the external device.

  Further, in the present embodiment, the example in which the launching device 1 is provided in the lower right side when viewed from the front with respect to the game board 2 has been described. May be provided. According to such an installation example, it is possible to prevent a return ball (a so-called foul ball) from being returned to the guide rail 20 by the shot ball launched on the board surface. In this case, it is preferable to provide a sensor for detecting a game ball at the out port 27. Further, a polishing unit that polishes the game ball may be provided on the transport path for transporting the game ball and the winning ball collected at the out port 27 to the launching device 1 on the upper right. The polishing unit includes, for example, a conveyance belt and a cloth polishing belt, and is configured to remove the dirt of the game ball. The configuration of the polishing unit is not limited to this, and various configurations capable of cleaning the game ball can be used.

  In this embodiment, an example in which the gaming machine according to the present invention is applied to a pachinko gaming machine has been described. However, the present invention is not limited thereto, and can be applied to other gaming machines such as a pachislot machine and a gaming machine. .

  As described above, the gaming machine according to the present invention makes it possible to visualize the communication state at a low cost while maintaining the fairness of the gaming machine, and to reduce the cost by reuse regardless of the type of gaming machine. It is useful for gaming machines such as pachinko machines or pachislot machines.
