Description

  The present invention relates to a gaming machine capable of preventing an illegal act of irradiating a radio wave to a proximity sensor that detects a game ball and erroneously detecting a winning.

  A pachinko gaming machine is equipped with a plurality of game ball detection switches for detecting that a game ball has passed through a winning opening for giving a predetermined number of prize balls or a predetermined gate. The game ball detection switch is configured to output a detection signal to the game control device when the passage of the game ball is detected.

  The game ball detection switch is, for example, a proximity sensor that detects a pachinko ball, and when a radio wave is applied to the proximity sensor from the outside due to the action of a sub-strate type PNP transistor provided therein, the pachinko ball passes therethrough. It is the structure which can prevent detecting this accidentally (for example, refer patent document 1).

Japanese Patent Laid-Open No. 03-292978

  Even if the proximity sensor disclosed in Patent Document 1 emits a radio wave from the outside in a state where the metal sphere is not in proximity, a signal of “no sphere” level is output from the comparison circuit 4. Never do. However, as shown in FIG. 5 of Patent Document 1, this proximity sensor irradiates the proximity sensor repeatedly with radio waves from the outside in a state where the metal sphere is in proximity, and from the comparison circuit 4 Would output a signal of the level of “no sphere” and “no sphere”.

  This can be realized by irradiating a radio wave from the outside with the coil portion of the proximity sensor clogged with a metal sphere having a diameter slightly larger than that of the pachinko sphere. In this case, as shown in FIG. 15, when the radio wave is irradiated, the output signal level from the proximity sensor becomes the same as the level indicating “no sphere”. There was a problem that it was determined that the pachinko ball passed through the coil portion of the sensor many times. In the gaming machine shown in FIG. 15, after detecting the state of “no ball”, the game machine won a prize when the state of “ball present” was continuously detected a plurality of times (eg, twice) at a predetermined sampling timing (eg, 2 ms). It is comprised so that it may judge.

  That is, the proximity sensor of the prior art of Patent Document 1 has a circuit configuration in which it is difficult to obtain the same signal output as when a pachinko sphere is detected by irradiating a radio wave from the outside when the metal sphere is not in proximity. However, it was possible to cause a malfunction when radio waves were irradiated from the outside with the metal spheres in close proximity. For this reason, there is a possibility that an illegal act of irradiating a radio wave in a state where the coil of the proximity sensor is intentionally clogged with a metal sphere may be performed.

  In view of the above problems, an object of the present invention is to provide a gaming machine capable of detecting fraudulent acts such as irradiation of radio waves in a state where a proximity sensor is clogged with a metal sphere.

  In a typical embodiment of the present invention, in a gaming machine comprising a detection means for detecting a game ball and a control means for performing control related to a game based on a detection signal from the detection means, the detection means is a predetermined A resonance frequency is set so as to include a first oscillation circuit that oscillates a high-frequency signal in a band and a first coil that detects proximity of a game ball, and includes a band of a high-frequency signal oscillated by the first oscillation circuit. The first LC resonance circuit, detection signal output means for outputting the detection signal to the control means when the first oscillation circuit is in an oscillation stop state, and substantially the same as the first oscillation circuit A second oscillation circuit that oscillates a high-frequency signal having a frequency of 2 and a second coil that is different from the first coil, and includes a band of a high-frequency signal oscillated by the second oscillation circuit. Resonance frequency is set A second LC resonance circuit, and an abnormality signal output means for outputting an abnormality signal indicating that an abnormality has occurred in the detection means to the control means, wherein the first LC resonance circuit includes the first LC resonance circuit. When the proximity of the game ball is detected by one coil, the first oscillation circuit is stopped from oscillating. On the other hand, when the proximity of the game ball is not detected by the first coil, the first The oscillation circuit is set in an oscillation state, the second LC resonance circuit normally sets the second oscillation circuit in an oscillation stop state, and the abnormal signal output means indicates that the second oscillation circuit is in an oscillation state. When detected, the abnormal signal is output, and the first coil and the second coil are arranged in a predetermined storage case.

  According to the present invention, it is difficult to output only a detection signal without outputting an abnormal signal when an improper act of irradiating a radio wave with the proximity sensor (detection means) clogged with a metal sphere is performed. Therefore, cheating can be prevented.

  Here, the flow of the game in the gaming machine according to the embodiment of the present invention, and the fluctuation display game (common figure fluctuation display game, first special figure fluctuation display game, second special figure fluctuation display game, decorative special figure fluctuation display game ) Will be described in detail.

  As described above, in the gaming machine according to the embodiment of the present invention, a game is played by launching a game ball (pachinko ball) from a hitting ball launcher (not shown) toward the game area 10a. The launched game balls flow down the game area 10a while changing the rolling direction by means of direction changing members such as obstacle nails arranged in various places in the game area 10a. The first start winning port 37, the normal variation winning device 36 or the special variable winning device 42 is won, or it flows into the out port 43 provided at the bottom of the gaming area 10a and is discharged from the gaming area. Then, when a game ball wins the general winning opening 44, the first starting winning opening 37, the normal variation winning apparatus 36 or the special variable winning apparatus 42, the number of winning balls corresponding to the type of the winning opening is discharged and controlled. It is discharged from a discharge device 151 controlled by the device 150.

  As described above, a gate switch 34a (see FIG. 2) for detecting a game ball that has passed through the general diagram start gate 34 is provided in the general diagram start gate 34. The usual start gate 34 is, for example, a non-contact type proximity sensor. When the game ball that has been driven into the game area 10a passes through the usual figure start gate 34, it is detected by the gate switch 34a, and the usual figure change display game is executed.

  In addition, a state in which the normal map change display game cannot be started, for example, when the normal map change display game has already been performed and the normal map change display game has not ended, or the result of the normal map change display game is a hit. When the normal variation winning device 36 is converted to the open state, when the game ball passes through the general figure start gate 34, if the normal figure start memory number is less than the upper limit of the normal figure start memory number, the normal figure start memory number is added (+1). As a result, one ordinary start memory is stored.

  In the normal chart start memory, a random number value for hit determination for determining a hit error of the normal figure change display game is stored, and when the random number value for hit determination coincides with the determination value, A specific result mode (specific result) is derived by hitting the normal map display game. The number of memorized map starts is displayed on a map reserved display provided on the map / special display 35.

  The normal map change display game is executed by a change display unit (general display display) 35c (see FIG. 2) provided in the general map / special map display 35. The general-purpose indicator 35c is composed of LEDs indicating normal identification information (normal diagrams, normal symbols) in the lit state, and indicating a deviation in the unlit state. Information variation is displayed, and after a predetermined variation display time has elapsed, the LED is turned on or off to display the result.

  When the random number value extracted at the time of detection of the passage to the general map start gate 34 is a winning value, the normal symbol displayed on the general map display 35c (see FIG. 2) is displayed in a predetermined stop display mode (specific result). Stops and hits. At this time, the second start winning port of the normal variation winning device 36 is driven by a built-in power solenoid 36b (see FIG. 2), so that the opening / closing member 36a is operated for a predetermined time (for example, 0.3 seconds). ), The game ball is allowed to enter the normal variation winning device 36.

  It should be noted that the universal map change display game may display the universal map change display game in a part of the display area of the display device 53. In this case, for example, numbers, symbols, character designs, etc. are used as identification symbols. This identification symbol is displayed by variably displaying for a predetermined time and then stopped and displayed. If the stop display of the normal map change display game results in a specific result, the normal map is hit.

  The first start winning opening 37 is provided with a first start opening switch (SW) 37d (see FIG. 2) for detecting a game ball won in the first start winning opening 37. When a game ball is detected by the first start port SW37d, a start right for starting the first special figure variation display game is generated. At this time, the start right to start the first special figure variation display game is stored as the first special figure start memory within a predetermined upper limit number (for example, 4).

  It should be noted that a state in which the first special figure fluctuation display game cannot be started, for example, either the first special figure fluctuation display game or the second special figure fluctuation display game has already been started, and the special figure fluctuation display game has ended. If there is no game, or the result of the special figure fluctuation display game is a big hit and the special fluctuation prize winning device 42 has been converted to the open state, when the game ball wins the first start prize opening 37, the first special figure If it is less than the upper limit number of start memories, the number of first special figure start memories is added (+1), and one first special figure start memory is additionally stored.

  Then, when the first special figure variation display game is ready to be started, a process for starting the first special figure variation display game by subtracting one from the start memory number stored in the first special figure variation display game is performed. It is carried out. However, in the gaming machine according to the present embodiment, the second special figure variation display game is executed in preference to the first special figure variation display game, so that the start memory (second special figure variation display game) is started. If the number of figure start memory is not zero, the first special figure variation display game is not started until the second special figure start memory number becomes zero.

  The first special figure starting memory stores a big hit determination random number value for determining a hit loss of the first special figure fluctuation display game, and starts the first special figure fluctuation display game. In the process to do this, it is determined whether or not the jackpot determination random number value matches the jackpot determination value. When the jackpot determination random number value matches the jackpot determination value, the first special figure variation display game becomes a jackpot, and a specific result mode (specific result) is derived. The first special figure starting memory number is displayed on a first special figure holding display provided in the general figure / special display 35.

  The first special figure fluctuation display game is executed by a fluctuation display section (first special figure display) 35a (see FIG. 2) provided in the general figure / special figure display 35. The first special figure indicator 35a is capable of expressing patterns of powers of 2 (n-th power) by 7-segment display LEDs (combination of a plurality of (n) LED points and the like (a combination of lighting / extinguishing)). The display information can be changed by updating the display of the LED, and a predetermined pattern can be displayed on the LED after a predetermined change display time has elapsed. Is displayed.

  Then, when the special figure random number extracted at the time of detection of winning at the first start winning opening 37 is a winning value, the special symbol displayed on the first special figure display 35a is in a predetermined stop display mode (specific result). Stop and hit a big hit. At this time, the special variable prize winning device 42 is converted into a state in which the open / close door 42a is opened for a predetermined time (for example, 30 seconds) by driving a built-in large prize opening solenoid 42b (see FIG. 2). Then, the winning of the game ball to the special variable winning device 42 is allowed.

  The opening / closing operation of the open / close door 42a is performed under any of the following conditions: a predetermined number (for example, 9) of game balls wins a prize winning opening, or a predetermined time (for example, 25 seconds) elapses from the opening of the prize winning opening. Opening the grand prize opening until 1 is achieved is defined as one round, and a control (cycle game) is performed that continues for a predetermined number of rounds (for example, 15 times).

  On the other hand, the normal variation winning device 36 includes a second starting port SW36d (see FIG. 2) including a proximity sensor for detecting a game ball that has passed through the second starting winning port of the normal variation winning device 36. It is done. When a game ball is detected by the second start port SW36d, a start right for starting the second special figure variation display game is generated. At this time, the right to start the second special figure variation display game is stored as the second special figure start memory within a predetermined upper limit number (for example, 4).

  Note that a state in which the second special figure fluctuation display game cannot be started, for example, either the first special figure fluctuation display game or the second special figure fluctuation display game has already been started, and the special figure fluctuation display game has ended. If there is no game, or if the result of the special figure variation display game is a big hit and the special variation prize winning device 42 is converted to the open state, the game ball will be awarded at the second starting prize opening of the normal variable prize winning device 36. If it is less than the upper limit number of the second special figure starting memory, the number of the second special figure starting memory is added (+1), and one second special figure starting memory is additionally stored.

  When the second special figure fluctuation display game is ready to be started, a process for starting the second special figure fluctuation display game by subtracting one from the start memory number stored in the second special figure fluctuation display game is performed. It is carried out.

  Note that the second special figure starting display memory stores a random number for determining the big hit for determining the miss of the second special figure fluctuation display game, and starts the second special figure fluctuation display game. In the process to do this, it is determined whether or not the jackpot determination random number value matches the jackpot determination value. When the jackpot determination random number value matches the jackpot determination value, the second special figure variation display game is a jackpot and a specific result mode (specific result) is derived. The second special figure starting memory number is displayed on a second special figure holding display provided on the general figure / special display 35.

  The second special figure fluctuation display game is executed by a fluctuation display part (second special figure display) 35b (see FIG. 2) provided in the general figure / special figure display 35. The second special figure display 35b is a display having the same configuration as that of the first special figure display 35a. The display of the display is updated to display the fluctuation of the identification information, and a predetermined fluctuation display time has elapsed. After that, the result is displayed by displaying a predetermined pattern on the display.

  When the special figure random number extracted at the time of detection of winning at the second start winning opening of the normal variation winning apparatus 36 is a winning value, the special symbol displayed on the second special figure display 35b is a predetermined stop display mode. Stops at (specific result) and becomes a big hit state. At this time, in the same way as when the first special figure fluctuation display game is a big hit, the built-in big prize opening solenoid 42b is driven to convert the open / close door 42a into a state of being opened for a predetermined time. The winning of the game ball to the special variable winning device 42 is allowed.

  The opening operation of the opening / closing door 42a is performed in the same manner as when the first special figure variation display game is a big hit, either when a predetermined number of game balls are won in the big winning opening or a predetermined time has elapsed since the opening of the big winning opening. Opening the grand prize opening until one of the conditions is achieved is defined as one round, and control is performed to continue this for a predetermined number of rounds.

  Note that the pachinko gaming machine according to the embodiment of the present invention corresponds to the results of the special figure fluctuation display game (including both the first special figure fluctuation display game and the second special figure fluctuation display game). The jackpot probability of the figure fluctuation display game may change, and the gaming state is always a low probability state (normal probability state) in which the special figure fluctuation display game is a big hit with a low probability, or a special figure than the low probability state. The variable display game is set to one of a high probability state in which the game is a big hit with a high probability. Note that the low probability state may be referred to as a non-probability variation gaming state, or the high probability state may be referred to as a probability variation gaming state.

  Furthermore, the gaming state of the pachinko gaming machine according to the embodiment of the present invention may change the opening frequency of the normal variation winning device 36 corresponding to the result of the special figure variation display game, and the gaming state is always It is set to either the suppression state where the opening frequency of the normal variation winning device 36 is low or the promotion state where the opening frequency of the normal variation winning device 36 is higher than the suppression state. Note that the suppression state may be referred to as a non-short game state, and the promotion state may be referred to as a short-time game state.

  In this promotion state, the execution time of the normal variation display game is controlled to be shorter than the execution time in the suppression state (for example, 10 seconds in the suppression state and 1 second in the promotion state). As a result, the number of times of opening of the normal variation winning device 36 per unit time is controlled to be substantially increased, and it becomes easier for the game ball to win the second start winning opening, resulting in the variation of the second special figure. The display game is easily executed.

  In the accelerated state, when the normal variation prize-winning device 36 is released as a result of the normal variation display game being won, the opening time may be controlled to be longer than the opening time in the suppressed state (for example, , 0.3 seconds in the restrained state and 2.9 seconds in the accelerated state). Further, in the accelerated state, the normal variation winning device 36 may be opened a plurality of times (for example, twice) instead of once for the result of one hit of the normal symbol variation display game. Further, in the promotion state, the probability that the hit result of the normal fluctuation display game is higher than the suppression state may be controlled. That is, in the accelerated state, the opening frequency of the normally variable winning device 36 increases more than in the suppressed state, and it becomes easier for the game ball to win the second start winning opening of the normally varying winning device 36, thereby displaying the second special figure variable display. A privilege that makes it easy to start the game is given.

  In this way, the special figure fluctuation display game (first special figure fluctuation display game and second special figure fluctuation display game) as an auxiliary game is executed by the general figure / special figure display 35 provided on the game board 10. After a plurality of pieces of identification information are variably displayed, a predetermined result mode is stopped and displayed. In this case, the second special figure fluctuation display game is executed with priority over the first special figure fluctuation display game, but each special figure fluctuation display game is not executed at the same time. Only the variable display game is executed.

  In addition, in the display device 53, in synchronization with the execution of the special figure fluctuation display game, a decorative special figure fluctuation display game that displays a plurality of types of identification information (for example, numbers, symbols, character designs, etc.) is executed. . And as a result of the special figure variation display game, when the display mode of the general figure / special map display 35 becomes a special result mode, it becomes a big win and becomes a special game state (so-called big hit state). Corresponding to this, the display mode of the decoration special figure variation display game of the display device 53 is also a special result mode (for example, any one of the numbers in the flat eyes such as “7, 7, 7”).

[Configuration of proximity sensor for gate switch]
FIG. 3 is an exploded perspective view showing the structure of the proximity sensor 200 used in the gate switch 34a of the universal start gate 34 according to the embodiment of the present invention.

  The proximity sensor 200 constituting the gate switch 34a includes a storage unit 210, a coil unit 220, and a control circuit unit 230.

  The storage unit 210 stores the coil unit 220 and the control circuit unit 230. The storage unit 210 includes a storage case lid 211a and a storage case bottom 211b. The storage case lid portion 211a and the storage case bottom portion 211b are fitted by members not shown. Further, at least one of the storage case lid portion 211a and the storage case bottom portion 211b is made of a transparent member so that the inside can be seen.

  The storage case lid portion 211a and the storage case bottom portion 211b are formed with game ball passage portions 212a and 212b which are circular through holes through which a game ball can pass. The game ball passage portion 212b formed on the bottom surface of the storage case bottom portion 211b is formed with an annular wall portion 213 that protrudes vertically upward from the bottom surface. When the game ball detection unit configured by the coil unit 220 and the control circuit unit 230 detects a game ball that has passed through the through hole, a signal is output to the control circuit unit 230.

  The coil unit 220 is formed in a cylindrical shape and is arranged on the same axis as the annular wall portion 213. And it is formed so that a game ball can pass the game ball passage part 212a of the storage case cover part 211a, the inside of the coil unit 220, and the game ball passage part 212b of the storage case bottom part 211b. The coil unit 220 includes a coil 221, a coil spool 222, and a shield member 223.

  The coil spool 222 is made of resin and is provided with a groove in the outer peripheral direction of the outer side surface, and a structure in which the coil 221 is embedded by winding a copper wire in an annular shape a plurality of times along the groove. It has become.

  Therefore, when a game ball passes through the game ball passage unit 212, the generation of an electromagnetic field is detected based on the voltage induced by the coil 221, and a signal corresponding to the detection result is supplied to the control circuit unit 230.

  The shield member 223 is made of a conductive member such as metal, surrounds the coil 221 and the coil spool 222, and shields an electromagnetic field from the outside. The shield member 223 includes a first shield member 223a and a second shield member 223b that are formed in an annular shape.

  The first shield member 223a is disposed so as to cover the coil spool 222 from above, and a wall portion is formed so as to protrude downward from the outer periphery to surround the coil 221. The second shield member 223b is disposed so as to cover the coil spool 222 from below, and a wall portion is formed so as to protrude upward from the outer periphery to surround the coil 221.

  Then, the first shield member 223a and the second shield member 223b are fitted to each other to form a cylindrical shape and surround the coil 221 and the coil spool 222. Therefore, even if a person who performs a fraudulent action tries to cause malfunction by irradiating the coil 221 with radio waves from the outside of the shield member 223, the shield member 223 shields it, so that the fraudulent action can be prevented.

  Further, in order to connect the coil 221 to the control circuit unit 230, the shield member 223 has openings so that both ends of the copper wire forming the coil 221 can be drawn from a part of the outer periphery of the shield member 223. . Note that since the opening is open on the back side of the gaming machine, there is almost no effect even when radio waves are irradiated from the front side of the gaming machine.

  The control circuit unit 230 is connected to both ends of the coil 221, and outputs a detection signal to the game control device 30 via the signal line 232 when detecting the voltage output by the passage of the game ball. In addition, two power supply lines 231 (a drive power supply line and a ground line of the control circuit unit 230) are connected to the control circuit unit 230, and necessary power is supplied from the power supply device.

  The gate switch 34a is configured to output a signal when the game ball passes the normal start gate 34, and only detects the passage of the game ball, so the control circuit unit 330 transfers the game control device 30 to the game control device 30. Only one signal line is connected.

[Composition of proximity sensor for prize opening]
FIG. 4 is an exploded perspective view showing the structure of the proximity sensor 300 that can output an abnormal signal when a radio wave is irradiated in a state where the metal sphere of the embodiment of the present invention is clogged.

  The proximity sensor 300 is configured to be able to detect an abnormality when a fraud in which a game ball is obtained illegally by irradiating radio waves. The proximity sensor 300 is used for the first start port SW37d, the second start port SW36d, the count SW 42c, and the winning ports SW44a to SW44a-n.

  The proximity sensor 300 includes a storage unit 310, a coil unit 320, and a control circuit unit 330.

  The storage unit 310 stores the coil unit 320 and the control circuit unit 330. The storage unit 310 includes a storage case lid 311a and a storage case bottom 311b. The storage case lid 311a and the storage case bottom 311b are mounted by constituent members not shown.

  The storage case lid 311a and the storage case bottom 311b are provided with game ball passage portions 312a and 312b that form through holes through which game balls can pass. Similar to the proximity sensor 200 shown in FIG. 3, the coil unit 320 and the control circuit unit 330 detect that the game ball has passed the game ball passage unit 312.

  The storage case bottom 311b is partitioned into three rows, and a game ball passage 312b is formed on the front side of the middle row. Further, a control circuit unit 330 is disposed on the back side of the middle row. Further, the game ball passage 312b formed on the front side of the middle row is formed with an annular wall portion 312c projecting vertically upward from the bottom surface.

  In addition, annular wall portions (a left annular wall portion 313 and a right annular wall portion 314) protruding upward from the bottom surface are formed on the front side of the left row and the right row of the storage case bottom portion 311b. Note that the insides of the left annular wall 313 and the right annular wall 314 do not penetrate. The diameters of the left annular wall portion 313 and the right annular wall portion 314 are substantially the same diameter as the game ball passage portion 312b, but are not limited thereto as will be described later.

  The proximity sensor 300 includes three coil units 320 (320a, 320b, and 320c), which are arranged in each row. The coil unit 320 has the same structure as that of the coil unit 220 shown in FIG. 3, and includes a coil, a coil spool, and a shield member. Each coil unit 320 is connected to the control circuit unit 330, and signals (a detection signal V1, an abnormal signal V2, and an abnormal signal V3, which will be described later) are sent to the game control device 30 via the corresponding three signal lines 332. Output.

  As described above, the middle row is formed with a game ball passage portion 312b that forms a through-hole through which a game ball can pass, so that the game ball can pass in the axial direction through the cylindrical coil unit 320a. Is arranged.

  A ferromagnetic body 340 formed in a cylindrical shape having a diameter slightly smaller than the inner diameter of the left annular wall 313 is fitted inside the left annular wall 313. Further, the coil unit 320b is disposed coaxially with the left annular wall 313, and the ferromagnetic body 340 is inserted through the inside. Therefore, the control circuit unit 330 always detects a state equivalent to a state in which a game ball is present inside the coil unit 320b. Further, even when the game ball passes through the game ball passage portion 312 formed in the middle row by the shield member of the coil unit 320b, the influence of the generated electromagnetic field can be prevented.

  A coil unit 320c is coaxially disposed on the right annular wall 314. Since nothing is inserted inside the coil unit 320c, the control circuit unit 330 always detects a state equivalent to a state where no game ball is present inside the coil unit 320c. Further, even when the game ball passes through the game ball passage portion 312 formed in the middle row by the shield member of the coil unit 320c, the influence of the generated electromagnetic field can be prevented.

  The control circuit unit 330 detects the generation of an electromagnetic field based on the voltage induced by the coil included in the coil unit 320 and outputs a signal corresponding to the detection result to the game control device 30. Three coil units 320 are connected to the control circuit unit 330 in the proximity sensor 300, and the control circuit unit 330 detects the generation of an electromagnetic field in each coil unit 320. Three signal lines 332 corresponding to each coil unit 320 are connected to the game control device 30 in the control circuit unit 330. Further, like the control circuit unit 230 of the proximity sensor 200 described above, two power supply lines 331 are connected to the control circuit unit 330, and necessary power is supplied from the power supply device.

  The coil unit 320a is in a state where a voltage is induced when the game ball passes, and a voltage is not induced when the game ball does not pass. The coil unit 320b disposed on the left annular wall 313 is in a state where voltage is always induced since the ferromagnetic body 340 is inserted. On the other hand, the coil unit 320c disposed on the right annular wall 314 is not inserted through anything, and a game ball or the like does not pass therethrough, so that no voltage is always induced.

  Note that changes in voltage and signal level induced by each coil when passing through the game ball and during radio wave irradiation will be described with reference to FIGS.

  Next, the configuration of the proximity sensor 300 shown in FIG. 4 will be further described. FIG. 5 is a block diagram showing a configuration of the proximity sensor 300 that can output an abnormal signal when a radio wave is irradiated in a state where the metal sphere is clogged according to the embodiment of the present invention.

  The proximity sensor 300 includes a sphere detection signal processing unit 350 and an abnormality determination signal processing unit 360. The sphere detection signal processing unit 350 is connected to a coil 321a included in the coil unit 320a.

  The sphere detection signal processing unit 350 includes a capacitor 351, an oscillation circuit 352, a determination circuit 353, and a detection signal output circuit 354. The ball detection signal processing unit 350 detects the generation of an electromagnetic field by detecting the induction of voltage by the coil 321a, and outputs a detection result (detection signal) to the game control device 30.

  More specifically, both ends of the capacitor 351 are connected in parallel with the coil 321a, and the end portion that becomes the upper voltage is grounded to the oscillation circuit 352, and the end portion that becomes the lower voltage is grounded. The oscillation circuit 352 is supplied with power from a power supply and is grounded, and supplies an oscillation output to the determination circuit 353. Note that the oscillation circuit 352 is set in an oscillation state in which a high frequency signal in a predetermined band is oscillated in a normal state (a state where the game ball is not present in the coil 321a), and the game ball is present in the coil 321a. When an electromagnetic field is generated when a game ball passes through the coil 321a, the oscillation is set to stop.

  Note that it is not necessary to completely stop the oscillation in the oscillation stopped state, and the oscillation output may be lowered to such an extent that the discriminating circuit 353 described later cannot detect the oscillation output. Therefore, there is no problem even if the resonance frequency of the LC resonance circuit 355 and the oscillation frequency of the oscillation circuit 352 are not completely the same. The resonance frequency of the LC resonance circuit 355 can be set to any frequency including the band of the oscillation output signal of the oscillation circuit 352 as long as the oscillation output of the oscillation circuit 352 can be lowered.

  The determination circuit 353 is a circuit for determining whether or not there is an oscillation output from the oscillation circuit 352. The determination circuit 353 is supplied with power from a power supply and is grounded. The threshold value is compared, and the comparison result is output to the detection signal output circuit 354. The detection signal output circuit 354 is supplied with power from the power source and is grounded, detects an electromagnetic field based on the comparison result of the determination circuit 353, and uses the detection result as a detection signal V1 via the signal line 332 to control the game control device. Output to 30.

  On the other hand, the abnormality determination signal processing unit 360 includes a first processing unit 360a connected to the coil 321b through which the ferromagnetic body 340 is inserted and a second processing unit 321c connected to the coil 321c through which the ferromagnetic body 340 is not inserted. And a processing unit 360b.

  Similar to the sphere detection signal processing unit 350, the first processing unit 360a and the second processing unit 360b are capacitors (361a, 361b), oscillation circuits (362a, 362b), discrimination circuits (363a, 363b), and detection signal circuits. (364a, 364b). The connection form of each configuration is the same as that of the signal processing unit 350 for detecting a sphere. The oscillation circuits (362a, 362b) oscillate high-frequency signals in substantially the same band as the oscillation circuit 352 of the sphere detection signal processing unit 350.

  In the first processing unit 360a, since the ferromagnetic body 340 is inserted through the coil 321b, the state is always the same as the state where the game ball is present (passed), and the oscillation circuit 362a is in the oscillation stop state. ing. Therefore, the oscillation circuit 352 is normally in an oscillation stop state, and the determination circuit 363a determines that an abnormality has occurred when the oscillation circuit 352 shifts to the oscillation state, and receives the abnormality signal V2 from the abnormality signal output circuit 364a. The signal is output via the signal line 332. Specifically, this is the case where a state in which a game ball is not passing is detected, for example, by radiating radio waves of a specific frequency from the outside.

  Note that the oscillation circuit 362a does not need to completely stop the oscillation in the oscillation stopped state, and may reduce the oscillation output to such an extent that the discrimination circuit 363a cannot detect the oscillation output. Therefore, there is no problem even if the resonance frequency of the LC resonance circuit 365a and the oscillation frequency of the oscillation circuit 362a are not completely the same. The resonance frequency of the LC resonance circuit 365a can be set to an arbitrary frequency including the band of the oscillation output signal of the oscillation circuit 362a as long as the oscillation output of the oscillation circuit 362a can be reduced.

  In the second processing unit 360b, nothing is inserted through the coil 321b, so the oscillation circuit 352 is in an oscillation state. Therefore, normally, the oscillation circuit 362b is in an oscillation state, and the determination circuit 363b determines that an abnormality has occurred when the oscillation circuit 362b shifts to the oscillation stop state, and outputs the abnormality signal V3 from the abnormality signal output circuit 364b. The signal is output via the signal line 332. Specifically, this is a case where a state in which a game ball has passed is detected, for example, by radiating radio waves of a specific frequency from the outside.

  Note that the oscillation circuit 362b does not need to completely stop the oscillation in the oscillation stop state, and may reduce the oscillation output to the extent that the discrimination circuit 363b cannot detect the oscillation output. Therefore, there is no problem even if the resonance frequency of the LC resonance circuit 365b and the oscillation frequency of the oscillation circuit 362b are not completely the same. The resonance frequency of the LC resonance circuit 365b can be set to any frequency including the band of the oscillation output signal of the oscillation circuit 362b as long as the oscillation output of the oscillation circuit 362b can be reduced.

  In the embodiment of the present invention, the size and the number of turns of each coil included in the coil unit 320a, the coil unit 320b, and the coil unit 320c are the same, specifically, the inductance of each coil is the same. Thus, the resonance frequencies of the LC resonance circuit 355, the LC resonance circuit 365a, and the LC resonance circuit 365b are unified. Therefore, it is possible to detect abnormalities caused by radio waves in the same band as the radio waves affecting the proximity sensor, and to detect non-detected radio waves that do not affect the detection of the game ball. It becomes possible to prevent.

  Furthermore, in order to obtain the effect of the embodiment of the present invention, the resonance frequency of the LC resonance circuit 355, the LC resonance circuit 365a, and the LC resonance circuit 365b only needs to be unified. What is necessary is just to be comprised so that the product with the electrostatic capacitance of this capacitor may become the same. Therefore, by increasing the capacitance of the connected capacitor while unifying the resonance frequency, the coil inductance can be reduced, that is, the number of turns of the coil can be reduced, or the coil diameter can be reduced. It becomes possible, and a coil unit can be reduced in size.

  Note that the resonance frequencies of the LC resonance circuit 355 and the LC resonance circuit 365a do not need to be set to completely the same value, and even if frequencies having slightly different values are set as long as an abnormal state can be detected. No problem. Similarly, the relationship between the resonance frequencies of the LC resonance circuit 355 and the LC resonance circuit 365b does not need to be set to the completely same value, and a frequency having a slightly different value is set as long as an abnormal state can be detected. There is no problem.

  In a modification of the embodiment of the present invention to be described later, a proximity sensor in which a coil unit for detecting an abnormality is miniaturized will be described.

  Hereinafter, a procedure for detecting the execution of fraud will be described. First, a procedure for erroneously detecting the proximity sensor will be described.

  Because the proximity of the game ball is detected by the proximity sensor for a moment when it falls, it is usually irradiated at the moment when the game ball is detected (the period in which the game ball is present inside the coil). Is very difficult. However, it is possible to always detect the passage of the game ball by clogging the detection unit with a metal ball slightly larger than the diameter of the game ball passage portion. At this time, it is possible to detect a state in which a game ball is not passing by irradiating a radio wave of a predetermined frequency toward the proximity sensor, and by repeating this, it is possible to erroneously detect the passage of the game ball.

  FIG. 6 illustrates a voltage change when an illegal act of erroneously detecting a winning is performed by irradiating a radio wave of a predetermined frequency in a state where the passing of the game ball according to the embodiment of the present invention is detected. FIG.

  From time t1 to time t2, the game ball is not passing (the game ball is not present inside the coil). At this time, the oscillation circuit 352 of the sphere detection signal processing unit 350 is in an oscillation state, and the voltage Va becomes larger than a predetermined threshold value (V0). The signal (V1) output from the detection signal output circuit 354 is HIGH.

  In addition, the oscillation circuit 362a of the first processing unit 360a of the abnormality determination signal processing unit 360 is in an oscillation stopped state because the gaming ball is detected by the ferromagnetic material 340, and the voltage Va is predetermined. It becomes smaller than the threshold value (V0). The signal (V2) output from the abnormal signal output circuit 364a is LOW.

  Furthermore, the oscillation circuit 362b of the second processing unit 360b of the abnormality determination signal processing unit 360 is in an oscillating state, and the voltage Vc is larger than a predetermined threshold value (V0). The signal (V3) output from the abnormal signal output circuit 364a is HIGH.

  Therefore, when the game ball has not passed, V1 is HIGH, V2 is LOW, and V3 is HIGH. In this state, a case where the proximity sensor is irradiated with radio waves from time t4 to time t5 will be described. The radio wave irradiated at this time has a frequency that causes a false recognition that the game ball does not pass if it is irradiated while the game ball is passing.

  Since the ball detection signal processing unit 350 is in a state in which no game ball passes, the voltage Va does not change greatly even when a radio wave that is misrecognized in a state in which no game ball passes through. Similarly, the voltage Vc does not change significantly in the second processing unit 360b of the abnormality determination signal processing unit 360. Therefore, both the signal V1 and the signal V3 remain unchanged and remain unchanged.

  On the other hand, in the first processing unit 360a of the abnormality determination signal processing unit 360, the ferromagnetic body 340 causes the voltage Vb to be smaller than the threshold value V0 corresponding to the detection state of the game ball. At this time, when the radio wave is irradiated, the voltage Vb becomes larger than the threshold value V0, and the signal V2 is set from LOW to HIGH. That is, when the signal V2 changes to HIGH, it can be determined that radio waves have been irradiated.

  Next, a case where radio waves are irradiated from time t6 to time t7 in the game ball detection state (from time t2 to time t3) will be described. Here, a case where a person who performs an illegal act intentionally generates a detection state of a game ball by the above-described method or the like will be described.

  Since the ball detection signal processing unit 350 is in a gaming ball detection state, the voltage Va is smaller than the threshold value V0. At this time, when a radio wave that is misrecognized in a state where no game ball is passing is irradiated, the voltage Va exceeds the threshold value V0, and the signal V1 is set to HIGH. Therefore, the ball detection signal processing unit 350 outputs a signal so that it is determined that the game ball has passed between time t2 and time t6. Note that the voltage Vc does not change significantly for the second processing unit 360b of the abnormality determination signal processing unit 360.

  On the other hand, in the first processing unit 360a of the abnormality determination signal processing unit 360, as described above, the voltage Vb is smaller than the threshold value V0 corresponding to the detection state of the game ball. At this time, when the radio wave is irradiated, the voltage Vb becomes larger than the threshold value V0, and the signal V2 is set to HIGH. That is, when the signal V2 changes to HIGH, it can be determined that fraud in which radio waves are irradiated has been performed.

  Even when radio waves are irradiated from the outside, only the oscillation circuit 362a of the first processing unit 360a of the abnormality determination signal processing unit 360 is stopped from oscillation, and the oscillation circuit 352 of the sphere detection signal processing unit 350 is If the oscillation state can be achieved, it is possible to execute an illegal act without determining that the abnormality has occurred. However, since the resonance frequencies of the LC resonance circuit 355 and the LC resonance circuit 365a are set to substantially the same value, it is very difficult to irradiate the radio wave from the outside so as not to be determined to be fraudulent. I can say that.

  As described above, fraud in which radio waves are irradiated can be detected by the first processing unit 360a of the abnormality determination signal processing unit 360. In addition, the abnormal signal output from the first processing unit 360a of the abnormality determination signal processing unit 360 is not always detected, but the abnormal signal is detected when the detection state of the game ball continues for a predetermined time. Good.

  Next, a case will be described in which the passage of the game ball is erroneously detected by irradiating the radio wave in a state where the game ball is not detected. In this case, a radio wave having a frequency for shifting the oscillation circuit from the oscillation state to the oscillation stop state is irradiated.

  FIG. 7 illustrates a voltage change when an illegal act of erroneously detecting a winning is performed by irradiating a radio wave of a predetermined frequency in a state where the passing of the game ball is not detected according to the embodiment of the present invention. FIG.

  In the example shown in FIG. 7, when the radio wave is irradiated, the voltage Va becomes smaller than the threshold value V0 when the game ball is in a non-detection state, so that the ball detection signal processing unit 350 has passed the game ball. judge. At this time, the first processing unit 360a of the abnormality determination signal processing unit 360 cannot detect an abnormality because the voltage Vb does not exceed the threshold value V0.

  On the other hand, since the voltage Vc becomes smaller than the threshold value V0 when the above-described radio wave is irradiated, the second processing unit 360b of the abnormality determination signal processing unit 360 detects the passage of the game ball that should not be possible. It will be. Therefore, when the second processing unit 360b of the abnormality determination signal processing unit 360 detects the passage of the game ball, it can be determined as abnormal.

  As described above, in the embodiment of the present invention, a fraudulent act of irradiating a radio wave to be in a non-detection state when a game ball is detected, and a radio wave to be in a detection state when no game ball is detected. It is possible to detect any fraudulent acts that are fraudulent.

  Since the gaming machine is installed in an environment where noise is likely to occur, it may be determined that an abnormality has occurred when an abnormal signal is continuously detected for a predetermined period, as will be described later. Good.

  Next, with reference to FIG.8 and FIG.9, the process regarding the game performed with the game control apparatus 30 is demonstrated. FIG. 8 is a flowchart of main processing executed by the game control apparatus 30 according to the embodiment of this invention. FIG. 9 is a flowchart illustrating a procedure of timer interrupt processing according to the embodiment of this invention.

  The game control device 30 executes a main process shown in FIG. 8 and a timer interruption process every predetermined time (for example, 4 msec) shown in FIG.

[Main processing (game control device)]
The main process shown in FIG. 8 is executed when the gaming machine is turned on, and is continuously executed until the power supply to the gaming machine is interrupted. For example, when a game machine is turned on to start a business at a game hall, or when it recovers from a power failure, the execution starts, and until the game machine is turned off to end the business at the game hall ( (Or until a power failure occurs).

  The game control device 30 first performs initialization processing (step S1) upon power-on as processing at the start of the program, and then performs power failure recovery processing (step S2).

  In the power failure recovery process, a process for resuming the game control in the gaming state at the time of the power failure using the data stored and stored in the RAM 31c (see FIG. 2) of the game control device 30 by the backup power supply 161 when the power failure occurs. Done. However, an initialization operation unit (not shown) is provided on the back side of the gaming machine, and if the initialization operation unit is operated when the gaming machine is turned on, the gaming state of the gaming machine is set in advance. Initialize to the specified state. As a result of this initialization, the lottery probability state of the special figure variation display game, which will be described later, becomes a low probability state, and the later-described normal power operating state (the operating state of the opening / closing member 36a of the normal variation winning device 36) is suppressed.

  Next, the game control device 30 executes main loop processing. In the main loop process, first, a process for starting an interrupt timer (step S3) is performed to start a CTC (counter timer circuit). Next, the game control device 30 performs a process for prohibiting interruption (step S4). Thereafter, the game control device 30 updates initial values of random numbers such as a jackpot determination random number (special figure determination random number) and a jackpot symbol random number (first special symbol random number, second special symbol random number). An initial value random number update process (step S5) for breaking the temporal regularity of random numbers is performed, and a process for permitting an interrupt (step S6) is performed.

  In the initial value random number update process in step S5, the same process is performed for each of the random numbers for the special figure 1 variable display game and the random numbers for the special figure 2 variable display game.

  In step S7, the game control apparatus 30 checks the power failure inspection area of the RAM 31c and determines whether or not a power failure has occurred. In the power failure inspection area of the RAM 31c, check data is stored when the power of the gaming machine is cut off due to a power failure, and the check data is not normally stored. Therefore, it is possible to determine whether or not a power failure has occurred by determining the presence or absence of check data in the power failure inspection area of the RAM 31c.

  If a power failure has not occurred (the result of step S7 is “N”), the process returns to the interrupt prohibition process of step S4, and thereafter, the game control device 30 repeats the processes of step S4 to step S7. On the other hand, when a power failure occurs (the result of step S7 is “Y”), the game control device 30 performs a power failure occurrence process in step S8. When a power failure occurs, the backup power source 161 (see FIG. 2) of the power supply device 160 supplies power that can execute the processing when the power failure occurs. Further, the backup power supply 161 supplies power necessary for maintaining the contents of the RAM 31c of the game control device 30 during a power failure. At this time, the backup power supply 161 can hold the game data for 2 to 3 days or more.

  In the power failure occurrence processing in step S8, first, processing for prohibiting interruption is performed, processing for turning off all output ports, and processing for clearing the power failure inspection area are performed. Then, after performing the process of saving the power failure recovery inspection area check data in the power failure recovery inspection area, performing the process of calculating the checksum when the RAM 31c is powered off, and performing the process of prohibiting access to the RAM 31c, the gaming machine Wait for the power to be turned off. Thus, by saving the power failure recovery inspection area check data in the power failure recovery inspection area and calculating and holding the checksum at the time of power interruption, the information stored in the RAM 31c before the power interruption is correctly backed up. It can be determined whether the power is turned on.

[Timer interrupt processing (game control device)]
Next, a timer interrupt process of the game control device 30 will be described with reference to FIG. The timer interrupt process is executed in a form of interrupting the main process in response to the generation of an interrupt signal (generated at a predetermined interval by the interrupt timer).

  In the timer interrupt process, the game control device 30 first performs a process of saving the register data (step S10). Next, input from various sensors (first start port SW37d, second start port SW36d, gate SW34a, winning port SW44a to 44n, count SW42c, glass frame opening SW146, inner frame opening SW121, etc.) and setting by various processes Based on the output data, an input / output process (step S11) is performed for processing an output for performing drive control of the big prize opening SOL42b, the ordinary electric power SOL36b, and the like. In step S11, a detection signal and an abnormality signal output from the proximity sensor of each switch are received, and it is determined whether an abnormality has occurred. This determination will be described with reference to FIG.

  In step S12, the game control device 30 performs a command transmission process for outputting the command set in the transmission buffer in various processes to the effect control device 40 or the like.

  In step S <b> 13, the game control device 30 updates a random number for determining whether the special figure fluctuation display game or the normal figure fluctuation display game is missed, or for determining the big hit symbol of the special figure fluctuation display game. Process 1 is performed. Thereafter, the game control device 30 updates the initial value of the random number and executes an initial value random number update process (step S14) for breaking the temporal regularity of the random number. As for the random numbers related to the special figure, the same processing is performed for each of the random numbers for the special figure 1 variable display game and the random numbers for the special figure 2 variable display game.

  In step S15, the game control device 30 performs a random number update process 2 for updating a random number for determining a variation pattern (execution mode) in the decoration special diagram variation display game related to the special diagram variation display game.

  In step S16, the game control device 30 determines whether or not signals are input from the first start port SW37d, the second start port SW36d, the gate SW34a, the winning ports SW44a to 44n, and the count SW42c (a signal indicating detection of a game ball). A prize opening switch monitoring process for monitoring whether or not the game has been input.

  Thereafter, the game control device 30 performs an error monitoring process (step S17) for monitoring each signal and error. At this time, in step S11, based on the detection signal and the abnormality signal output from the proximity sensor of each switch, it is determined whether or not an illegal act has been executed. If it is determined that an illegal act has been executed, processing necessary for outputting an alarm sound or displaying an error screen is executed.

  Further, the game control device 30 performs a special figure game process (step S18) for performing a process related to the special figure variable display game, and performs a general figure game process (step S19) for performing a process related to the general variable display game.

  The game control device 30 performs segment LED editing processing (step S20) related to the segment LED that displays various information related to the game, and sets the signal output to the external management device 190 (see FIG. 2) in the output buffer. Processing (step S21) is performed. Then, the game control device 30 performs an interrupt end declaration process in step S22, and performs a process of restoring the saved register data in step S23. And the game control apparatus 30 performs the process which permits an interruption in step S24, and complete | finishes a timer interruption process.

[Change in signal output from proximity sensor]
FIG. 10 is a diagram illustrating an example of changes in the signal levels of the detection signal V1 and the abnormality signal V2 according to the embodiment of this invention.

  As described above, since the gaming machine is installed in a place where noise is likely to occur, whether or not the signal level has changed is determined to have changed when the changed signal level continues for a predetermined period. . In the embodiment of the present invention, it is determined that the signal level has changed when a timer interrupt (FIG. 9) has occurred at least twice after the signal level has changed. In addition, the broken line of FIG. 10 has shown the generation | occurrence | production interval of the timer interruption.

  Therefore, as shown in FIG. 10, at the timings A to D when the abnormal signal V2 changes, the occurrence of the timer interruption is only once in the period in which the abnormal signal V2 is LOW indicating abnormality. judge.

  On the other hand, at timing E, since the occurrence of the timer interrupt has occurred twice or more during the period in which the abnormal signal V2 is LOW indicating abnormality, it is determined that the signal level has changed to LOW indicating abnormality. At this time, since the signal level of the detection signal V1 has also changed to LOW indicating winning, it can be determined that there is a high probability that fraud is being performed.

  If it is determined that the cheating is performed, the game control device 30 turns on the display LED 35d of the game hall state, transmits a command to the effect control device 40, and outputs an alarm sound from the speaker 145. Further, it may be controlled so that all winning signals are ignored until the warning is released to the employees of the game hall.

[Overview of Special Figure Game Processing]
Further, in the game control device 30, as will be described later in detail, in the special game processing in step S18, based on the input of the detection signal of the game ball from the first start port SW37d provided in the first start winning port 37. Then, the random number for determining the big hit of the special figure 1 variable display game is extracted and stored in the RAM 31c as a special figure 1 start memory up to a predetermined upper limit number (for example, 4). Similarly, based on the input of the detection signal of the game ball from the second start opening SW36d provided in the normal variation winning device 36, a random number for jackpot determination of the special figure 2 variation display game is extracted and stored in the RAM 31c with a predetermined upper limit. A process of storing up to a number (for example, 4) as the special figure 2 start memory is performed.

  At the start of the special figure 1 fluctuation display game based on the special figure 1 start memory, the game control device 30 uses the jackpot determination random number value stored in the special figure 1 start memory and the special figure 1 fluctuation stored in the ROM 31b. Compared with the big hit determination value for the display game, a process of determining the hit loss of the special figure 1 variable display game is performed. After this processing, 1 is subtracted from the special figure 1 start memory number.

  Similarly, the game control device 30 stores the jackpot determination random number value stored in the special figure 2 start memory at the start of the special figure 2 variable display game based on the special figure 2 start memory. Compared with the jackpot determination value for the variation display game in FIG. 2, a process of determining a hit out of the special diagram 2 variation display game is performed. After this processing, 1 is subtracted from the special figure 2 starting memory number.

  The game control device 30 determines the variation pattern (execution mode) based on the variation pattern random number in the processing based on either the special figure 1 start memory or the special figure 2 start memory (see FIGS. 15 and 16). Further, the game control device 30 performs a process of selecting a special result mode based on the jackpot symbol random number when the jackpot determination random number value matches the jackpot determination value. The game control device 30 displays the special identification information on the special figure 1 display 35a or the special figure 2 display 35b on the special figure 1 display 35a or the special figure 2 display 35b on the basis of the determination result of the start memory as described above, and then stops and displays the special figure change display. A process for displaying a game is executed.

  Here, as described above, the probability state from which the special result mode is derived in the special figure variation display game has two probability states: a low probability state (normal probability state) and a high probability state (probability variation state). In the game control device 30, any one probability state is set. The high probability state is a state in which the probability of a jackpot result in the special figure variation display game is higher than that in the low probability state. In the low probability state, a predetermined number of first determination values are set as specific values, and this specific value (first determination value) is compared with a big hit determination random number value. Yes. Further, in the high probability state, the first determination value and the second determination value different from the first determination value are set as the specific value, and the specific value (first determination value, second determination value) and the jackpot determination random number value Are compared, and if they match, it is determined that the game is a big hit. In this way, the game control device 30 selects and sets the lottery probability that makes the result of the special figure variation display game a special result from among a plurality of preset candidates (low probability state and high probability state). Derived probability setting means.

  If a special result is derived in a special figure variation display game and a certain condition is met (if a specific special result mode (high probability pattern)), the probability state is increased after the special game state ends. Probability state. Moreover, even if it becomes a high probability state based on the result aspect of either the special figure 1 fluctuation display game or the special figure 2 fluctuation display game, the special figure 1 fluctuation display game and the special figure 2 fluctuation display game Both are in a high probability state. When a special result is derived in the special figure fluctuation display game in the case of the probability state, the special figure 1 fluctuation display is performed regardless of whether or not the special result mode is accompanied by the establishment of the predetermined condition. Both the game and the special figure 2 variable display game are once in the normal probability state. And when it is a special result aspect accompanied by establishment of predetermined conditions, it will be in a high probability state again after completion | finish of a special game state. In the case of a special result mode (normal symbol) that is not accompanied by the establishment of a predetermined condition, the normal probability state is maintained as it is even after the special game state is ended.

  As described above, the operation state of the normal variation winning device 36 includes a suppression state and a promotion state. Depending on the type of the special game state, the special game state is displayed for a predetermined number of times after the special game state ends. It is determined in which operating state the normal variation winning device 36 operates.

  In addition, the game control device 30 determines a jackpot determination random number value, a jackpot symbol random number, a variation pattern random number, etc. stored in the special figure 1 startup memory at a predetermined timing (arbitrary timing such as a start winning prize). A pre-reading process is performed to determine whether or not the special figure 1 variable display game is missed, the jackpot symbol (special result type), and the presence or absence of reach. Similarly, the game control device 30 determines a jackpot determination random number, a jackpot symbol random number, a variation pattern random number, etc. stored in the special figure 2 startup memory at a predetermined timing (any timing such as a start winning prize). And a pre-reading process for determining whether or not the big hit or miss of the special figure 2 variable display game, the big win symbol (special result mode type), or reach has occurred. These determination results are transmitted from the game control device 30 to the effect control device 40 as result information. Note that for the special figure 2 starting memory, the prefetching process is always performed regardless of the gaming state. Further, for the special figure 1 start memory, the pre-reading process is not performed when the operation state of the normal variation winning device 36 is the acceleration state or in the special game state. Or, even if the pre-reading process is performed, the advance notice based on the result is not performed.

  Here, the reach (reach state) is a state in which the variable display game is being executed on the display device 53 and is a state in which it is notified that the execution result may become a special result mode. It is. In the gaming machine of the present embodiment, when the execution result of the variable display game becomes a special result mode, a gaming state (special gaming state) in which the gaming state is advantageous for the player occurs.

  For example, the decorative special figure fluctuation display game displayed on the display device 53 corresponding to the special figure fluctuation display game (the first special figure fluctuation display game and the second special figure fluctuation display game) When the right variation display area displays a plurality of pieces of identification information for a predetermined period of time and then stops the variation display in the order of left, right, and middle, and displays the result mode, the left and right variations In the display area, the state in which the variable display is stopped in a state where the condition for the special result mode is satisfied (for example, the same identification information) is the reach state. In addition to this, when the variable display of all the variable display areas is temporarily stopped, the condition that the special result mode is satisfied in any two variable display areas among the left, middle, and right (for example, the same identification information It is also possible to set the reach state (except for the special result mode) to the reach state, and display the remaining one variable display area in a variable manner from the reach state. This reach state includes a plurality of reach effects, and normal reach, special reach 1 (SP1 reach), and special reach 2 (SP2 reach) are different reach effects that have different possibilities (reliability) of special results. Is set. In addition, this reach state is included in the variation display mode of the decoration special diagram variation display game that occurs at least in the case where the special result mode is derived in the special diagram variation display game (in the case of a big hit). It has become. That is, it may be included in the variation display mode of the decoration special diagram variation display game, which occurs in response to the case where the special result mode is not derived in the special diagram variation display game (when it is out of place). Therefore, the state in which the reach state has occurred is a state that is more likely to be a big hit than the case in which the reach state does not occur.

  In the game control device 30, when the result of the special figure variation display game is a big hit, a special result mode is displayed on the special figure display and a process for generating a special game state is performed. The special result mode displayed on the special figure display is determined based on the big hit symbol random number extracted and stored simultaneously with the big hit judgment random number value. When the result of the special figure variation display game is out of control, control is performed to display the result form of the deviation on the corresponding special figure display.

  In addition, in the game control device 30, as a process for generating a special game state, for example, a control that opens the open / close door 42a of the special variable prize winning device 42 by the big prize opening SOL 42b and allows the game ball to flow into the big prize opening. I do. Then, until the condition that either a predetermined number (for example, nine) of game balls wins the grand prize opening or a predetermined time (for example, 25 seconds) elapses from the opening of the big prize opening is achieved. Opening the mouth is defined as one round, and control (cycle game) is performed in which this is continued for a predetermined number of rounds (for example, 15 times). Thus, the gaming machine functions as a gaming machine that generates a special gaming state that can give a predetermined gaming value to the player based on the result mode of the special figure variation display game.

  Furthermore, in the game control apparatus 30, based on the detection signal of the game ball input from the sensors (first start port SW37d, second start port SW36d, winning port SW44a to 44n, count SW42c) provided in various winning ports. A process for controlling the discharge and firing control device 150 so that a predetermined number of game balls are paid out from the discharge device 151 is performed.

  In the effect control device 40, based on a command signal (change time command, change stop command, etc.) from the game control device 30, a special figure change display game (first special figure change display game and second special figure change is displayed on the display device 53. The display special display variation display game corresponding to the display game) is controlled.

  Here, in the special result mode, a plurality of types having different execution value of the special game state and the additional game value given to the player after the end of the special game state are set. The special result mode is selected on the basis of this. That is, it can be said that the amount of additional game value is determined based on the jackpot symbol random number. Note that the execution mode of the special game state in the gaming machine of the present embodiment indicates the number of rounds executed in the special game state and the time for which the big prize opening is opened. Further, the additional game value means that the probability state is set to a high probability state until the next special result mode is derived after the special game state ends, or the operation state of the normal variation winning device 36 after the special game state ends, For example, the game is put into a promotion state until a predetermined number of special figure fluctuation display games (the first special figure fluctuation display game and the second special figure fluctuation display game) are executed.

[Special Figure Game Processing]
Next, the details of the special game process (step S18) in the timer interruption process of FIG. 9 will be described with reference to FIG. FIG. 11 is a flowchart showing a procedure of special figure game processing according to the embodiment of the present invention.

  In step S30, the game control device 30 monitors the winnings of the game balls at the first start winning port 37 (see FIG. 1) and the second starting winning port of the normal variation winning device 36 (see FIG. 1). Based on this, the start port SW monitoring process for storing various random number values is executed.

  In step S31, the game control device 30 performs a count switch monitoring process for monitoring an input from the count SW 42c (see FIG. 2).

  In step S32, the game control apparatus 30 determines whether or not the special figure game process timer set in each process of steps S36 to S42 is zero.

  When it is determined in step S32 that the special figure game processing timer is not 0, the game control device 30 updates the special figure game processing timer by -1 (step S33), and the updated special figure game processing timer is timed. It is determined whether or not it has become 0 (step S34). When the special figure game process timer has timed out, the game control device 30 executes the process of step S35, and when the special figure game process timer has not expired, the game control apparatus 30 executes the process of step S44. To do.

  On the other hand, if it is determined in step S32 that the special figure game process timer is 0, or if it is determined in step S34 that the special figure game process timer has expired, the game control device 30 determines the game process number. And a game branching process (step S35) for selecting a process to be executed based on the acquired game process number is performed.

  When the game process number is 0, in step S36, the game control device 30 monitors the start of fluctuation of the special figure variation display game, sets the start of fluctuation of the special figure fluctuation display game, the setting of effects, and the special figure. A special figure routine process for setting information necessary for performing the process during the fluctuation is executed. In the special figure routine process, information related to the fluctuation of the special figure fluctuation display game is set, and a process or special figure for decrementing the start memory by one in accordance with the execution of the special figure fluctuation display game based on the start memory. A process for setting a change time in a change display game is performed.

  When the game process number is 1, in step S37, the game control device 30 has information necessary for performing the special figure display process in step S38 (such as a result stop display time in the special figure variable display game). The special figure changing process for setting is executed.

  If the game process number is 2, in step S38, the game control device 30 executes a special figure display process. In the special figure display processing, when the result of the special figure fluctuation display game is a big hit, information necessary for performing the fanfare interval process in step S39 is set, and the result of the special figure fluctuation display game is out of sync In addition, information necessary for performing the special figure routine processing in step S36 is set.

  When the game process number is 3, in step S39, the game control device 30 executes a fanfare interval process for performing a process such as updating the number of times the special winning opening is opened in the special game state.

  If the game process number is 4, in step S40, the game control device 30 performs a special prize opening opening process. If the special game state is not the final round, the information necessary for performing the fanfare interval processing in step S39 is set in the process for opening the big prize opening. If the special game state is the final round, the special game state end screen is displayed. Information necessary for setting the command and performing the winning ball remaining ball processing in step S41 is set.

  If the game process number is 5, in step S41, the game control device 30 performs a big winning opening remaining ball process. In the special winning opening remaining ball processing, when the special gaming state is the final round, a time is set until all the gaming balls remaining in the special winning opening are detected by the count SW 42c after the special winning opening is closed. .

  If the game process number is 6, in step S42, the game control device 30 executes a big hit end process. In the big hit end process, a process for ending the special gaming state is performed, and information necessary for performing the special figure routine process in step S36 is set.

  After performing the processing of steps S36 to S42 based on the game processing number, in step S43, the game control device 30 executes table data saving processing for saving various set data. Thereafter, the game control device 30 executes a special figure 1 fluctuation control process (step S44) for updating the game process timer of the special figure 1 fluctuation display game, etc., and updating the game process timer of the special figure 2 fluctuation display game, etc. The special figure 2 fluctuation control process (step S45) is performed, and the special figure game process is terminated.

[Start-up SW monitoring process]
With reference to FIG. 12, the details of the start port SW monitoring process (step S30) in the special game process of FIG. 11 will be described. FIG. 12 is a flowchart illustrating a procedure of the start port SW monitoring process according to the embodiment of this invention.

  In the start port SW monitoring process, the game control device 30 first determines whether or not there is a first start prize (step S50). Whether or not there is a winning at the first starting winning opening 37 is determined by the presence or absence of a detection signal of a game ball output from the first starting opening SW 37d when there is a winning at the first starting winning opening 37. . If there is no first start prize, the game control device 30 executes the process of step S51. On the other hand, when there is a first start winning, the game control device 30 executes the special figure start port SW common process of step S54 and ends the start port SW monitoring process. The details of the special figure start port SW common process will be described later with reference to FIG.

  In step S51, the game control device 30 determines whether or not a normal power operation is in progress. The game control device 30 determines whether or not the opening / closing member 36a of the normal variation winning device 36 serving as a normal electric (ordinary electric accessory) is in an open state in which a game ball can be won. If the opening / closing member 36a is in the open state and is operating normally, the game control device 30 executes the process of step S53. On the other hand, when the opening / closing member 36a is in the closed state and is not operating in normal power, the game control device 30 executes the process of step S52.

  In step S52, the game control device 30 determines whether or not an illegal winning error has occurred. The game control device 30 determines whether or not there is an illegal winning that has occurred in a state where the opening / closing member 36a of the normal variation winning device 36 is in a closed state. Note that a winning detected in a predetermined period after the opening / closing member 36a of the normal variation winning device 36 is closed is determined not to be an illegal winning. If an illegal winning error has occurred, the game control device 30 ends the start port SW monitoring process. On the other hand, when the illegal winning error has not occurred, the game control device 30 executes the process of step S53.

  In step S53, the game control device 30 determines whether or not there is a second start prize (winning to the second start prize port of the normal variation prize winning device 36). Whether or not there is a prize at the second start prize opening of the normal variation prize winning device 36 is whether or not there is a detection signal of the game ball output from the second start slot SW36d when there is a prize at the second start prize prize opening. Is determined by When there is no second start winning, the game control device 30 ends the start port SW monitoring process. On the other hand, when there is the second start winning, the game control device 30 executes the special figure start port SW common process of step S54 and ends the start port SW monitoring process.

[Special figure start port SW common processing]
With reference to FIG. 13, the details of the special figure start port SW common process (step S54) in the start port SW monitoring process of FIG. FIG. 13 is a flowchart showing the procedure of the special figure start port SW common process according to the embodiment of the present invention.

  In the special figure start port SW common process, the game control device 30 first executes a process of setting a corresponding start winning flag (step S60). The game control device 30 sets the start winning flag based on which of the first starting winning port 37 and the second starting winning port of the normal variation winning device 36 is started by the winning of the special figure starting port SW common processing. Set. As the start winning flag, when the special figure starting port SW common process is started by winning the first starting winning port 37, the special figure 1 flag is set, and the normal variable winning device 36 is set to the second starting winning port. When the special figure start port SW common process is started by winning a prize, the special figure 2 flag is set. In the following processing, if the special figure 1 flag is set, the special figure 1 start storage process is performed as a corresponding process, and if the special figure 2 flag is set, the special figure 2 start storage is performed as a corresponding process. Is processed.

  In step S61, the game control device 30 determines whether or not the corresponding hold is an upper limit (for example, 4). If the corresponding start memory cannot be stored any more and the corresponding hold is the upper limit, the game control device 30 ends the present process and ends the start port SW monitoring process. On the other hand, if the corresponding hold is not the upper limit, the game control device 30 executes a process of incrementing the corresponding start memory number by 1 in step S62, and then executes a process of step S63.

  In step S63, the game control device 30 executes a process for setting the number-of-holds information. The game control device 30 sets the number-of-holds information, which is information on the number of start memories, based on the corresponding start memory number being incremented by one. The number-of-holds information is transmitted to the effect control device 40 at a later timing as one of the hold information commands including information related to the start memory.

  Thereafter, the game control device 30 acquires the corresponding jackpot determination random number (step S64), the corresponding jackpot symbol random number (step S65), and the corresponding special figure variation display game variation pattern random number. The process (step S66) to perform is performed. Further, in step S67, the game control device 30 executes a special figure hold information determination process. In the special figure hold information determination process, a prefetch process is performed in which the result related information corresponding to the start memory is determined before the start timing of the special figure variation display game based on the corresponding start memory.

  Then, the game control device 30 stores the corresponding jackpot determination random number (step S68), stores the corresponding jackpot symbol random number (step S69), and stores the corresponding variation pattern random number (step S70). Execute. In the process of storing these various random numbers (steps S68 to S70), the game control device 30 stores the acquired various random number values in the various random number value saving areas set in accordance with the updated starting storage number. Process.

  In step S71, the game control device 30 executes a process of setting a hold information command, ends the process, and ends the start port SW monitoring process. The hold information command is transmitted to the effect control device 40 later.

[Effect of the embodiment]
As described above, according to the embodiment of the present invention, a metal ball is clogged in the game ball passage portion of the start port and the radio wave having a predetermined frequency is directed toward the proximity sensor while maintaining the detection state of the game ball. , It is possible to detect a state in which the game ball is not passing through and to prevent an illegal act of erroneously detecting the passing of the game ball.

[Modification]
In the embodiment of the present invention, in addition to the coil unit that detects the passage of the game ball, the coil unit of the same size is sandwiched in order to detect an abnormality. However, such a configuration may cause a problem that the size is increased as compared with a conventional proximity sensor without an abnormality detection coil.

  Accordingly, as a modification of the embodiment of the present invention, a proximity sensor having a size smaller than that of the proximity sensor of FIG. 4 will be described while maintaining the effects of the present invention by disposing an abnormality detection coil in a small size. .

  FIG. 14 is an exploded perspective view showing the structure of the proximity sensor 400 that can output an abnormal signal when a radio wave is irradiated in a state in which the metal sphere according to the modification of the embodiment of the present invention is clogged. The function of the proximity sensor 400 of this modification is the same as that of the proximity sensor 300 shown in FIG. 4, and the block diagram is the same as that shown in FIG.

  The storage unit 410 includes a storage lid 411a and a storage bottom 411b. The storage lid 411a and the storage bottom 411b are fastened by screwing screws into screw holes 414 that penetrate the storage lid 411a and screw holes 415 formed in the storage bottom 411b.

  In this modification, as shown in FIG. 14, a game ball passage portion 412b is formed together with an annular wall portion 412c, and a coil unit 420a is disposed so as to be able to penetrate the game ball passage portion 412b. The coil unit 420a may be the same as the coil unit 320a shown in FIG.

  Further, as shown in FIG. 14, the coil units 420b and 420c including the abnormality detecting coil in the proximity sensor 400 of this modification are smaller than the coil unit 420a for detecting the passage of the game ball. . However, since the inductance is reduced by downsizing the coil unit, as described above, the resonance frequency in all the LC resonance circuits is unified by increasing the capacitance of the capacitor corresponding to each coil unit. To do.

  Further, the coil unit 420b and the coil unit 420c are disposed between the control circuit portion 430, the annular wall portion 412c for disposing the coil unit 420a, and the outer frame portion 417 formed vertically above the storage bottom portion 411b. .

  The coil unit 420b corresponds to the coil unit 320b of FIG. In the coil unit 320b of FIG. 4, a ferromagnetic body 340 is inserted through the coil in order to detect an illegal act of irradiating the proximity sensor with radio waves in the detection state of the game ball. On the other hand, in this modified example, a screw for fixing the storage lid 411a and the storage bottom 411b is used instead of the ferromagnetic body 340. In this case, a ferromagnetic material is used for the screw material. The coil unit 420b is disposed at a predetermined position by inserting the screw hole 415 and the screw.

  On the other hand, the coil unit 420c corresponds to the coil unit 320c of FIG. The coil unit 320c outputs a detection signal when a radio wave is irradiated from the surroundings when the game ball is not detected, but the coil unit 420c of this modification also has the same function.

  The storage bottom 411b is formed with a resin projection 416 having the same outer diameter as the screw hole 415 and the same resin as the storage bottom 411b on the opposite side of the screw hole 415. The coil unit 420c is disposed at a predetermined position by inserting the protrusion 416.

  The ferromagnetic material inserted into the coil unit 420b is not necessarily a screw, and may be a fastening member such as a rivet or a simple iron core that does not function as a fastening member. Moreover, the structure which inserts the fastening member which is not a ferromagnetic body inside the coil unit 420c, and fastens the storage cover part 411a and the storage bottom part 411b may be sufficient.

  Further, the sizes of the diameters of the coil unit 420b and the coil unit 420c may be unified or non-uniform. Further, the coils used in the coil unit 420b and the coil unit 420c may or may not have the same number of turns.

  As described above, in the modified example of the embodiment of the present invention, it is possible to obtain the same effect as the proximity sensor of the embodiment of the present invention while suppressing an increase in the size of the proximity sensor.

  The embodiment disclosed this time is illustrative in all points and is not restrictive. The scope of the present invention is shown not by the above description of the invention but by the scope of claims, and is intended to include all modifications within the scope and meaning equivalent to the scope of claims.

  As described above, the present invention can be applied to a gaming machine including a proximity sensor that detects passage of a game ball.
