  Below the variation display device 9, a start winning device 15 having a first start port 15a and a second start port 15b as a winning area capable of receiving a pachinko ball is provided. In the start winning device 15, the first start port 15a is provided in the upper part, and the second start port 15b is provided in the lower part. A pair of movable pieces 13 and 13 are provided on the left and right sides of the second start port 15b in such a manner that an opening / closing operation can be performed. The first start port 15a is open upward and is always in a state where a pachinko ball can enter (accept). On the other hand, the second start port 15b is provided with a structure around the first start port 15a above and the movable pieces 13 and 13 are provided on the left and right, so that the movable pieces 13 and 13 are in a closed state. When the movable pieces 13 and 13 are in an open state, the pachinko ball can enter (accept). Thus, the first start port 15a does not change the easiness of winning, and the second start port 15b changes the easiness of winning according to the opening / closing operation of the movable pieces 13, 13.

  The starting prize-winning device 15 is able to win in the state where the movable pieces 13 and 13 are in the closed state, although it is difficult to win in the second starting port 15b (that is, the pachinko ball has won a prize). It may be configured to be difficult). In addition, the start winning device 15 may be provided with only the first start port 15a that does not change the easiness of winning as a start port, and it is easy to win by opening and closing the movable pieces 13, 13. Only the second start port 15b whose height changes may be provided.

  The movable pieces 13 and 13 of the start prize-winning device 15 are driven by the solenoid 16 when an opening condition described later is satisfied, so that the movable pieces 13 and 13 are opened from the closed state for a predetermined period and then closed. When the movable pieces 13 and 13 of the start winning device 15 are in the open state, the pachinko ball is easy to win the second start port 15b (easy to start start) and is advantageous to the player (first state). ) On the other hand, when the movable pieces 13 and 13 of the start winning device 15 are in the closed state, the pachinko ball does not win the second start opening 15b (it becomes difficult to start winning), which is a disadvantageous state for the player (second state). State). The winning ball that has entered the first start port 15a is guided to the back of the game board 6 and detected by the first start port switch 14a. The winning ball that has entered the second start port 15b is guided to the back of the game board 6 and detected by the second start port switch 14b.

  The predetermined number of the game board 6 displays four numbers indicating the number of valid winning balls that have entered the first starting port switch 14a or the second starting port switch 14b, that is, the number of reserved memories (also referred to as starting memory or starting winning memory). A special symbol storage memory display 18 (see FIG. 3) is provided. The special symbol reservation storage display 18 displays up to four reservation storage numbers in the order of winning. The special symbol hold memory display 18 increases the stored data in the hold memory by 1 and increases the number of LEDs in the lit state by 1 every time there is a start winning in the first start port 15a or the second start port 15b. Each time the special symbol display 8 starts the variable display, the special symbol storage memory display 18 decreases the storage data of the storage by 1 and decreases the number of LEDs in the lit state by 1 (that is, one LED Is turned off. Specifically, the special symbol hold storage display 18 shifts the lighting state every time the special symbol display 8 starts the variable display. In this example, an upper limit number (up to 4) is provided for the number of reserved memories by winning to the first start port 15a or the second start port 15b. However, the present invention is not limited to this, and the upper limit number of the reserved storage number may be a value of 4 or more, or may be a value less than 4.

  A special variable winning ball device 20 using an opening / closing plate that is opened and closed by a solenoid 21 is provided below the start winning device 15. The special variable winning ball apparatus 20 is provided with a big winning opening that is opened and closed by an opening / closing plate, and the opening / closing plate is controlled to an open state (first state) advantageous to the player in the big hit gaming state, and the big hit gaming state In other states, the open / close plate is controlled to a closed state (second state) which is disadvantageous to the player. As described above, the special variable winning ball apparatus 20 satisfies the release condition when it enters the big hit gaming state. Of the winning balls that are won in the special variable winning ball apparatus 20 and guided to the back of the game board 6, the winning ball that has entered one (V winning area: special area) and the pachinko ball that has entered the other area are counted as they are. 23. A solenoid 21a (see FIG. 3) for switching the route in the special winning opening is also provided on the back of the game board 6. In addition, a magnetic sensor 43 for detecting fraud using a magnet is provided on the back of the game board 6 (see FIG. 1).

  When the pachinko ball passes through the gate 32 and is detected by the gate switch 32a, the variable display on the normal symbol display 10 which displays the normal symbols as a plurality of types of identification information in a variable manner is started. In this embodiment, left and right LEDs (not shown) are turned on alternately by turning on the LEDs alternately. For example, if the left LED is turned on at the end of the change display, it becomes a hit. . When the stop symbol on the normal symbol display 10 becomes a predetermined symbol (winning symbol), the opening condition of the movable pieces 13 and 13 of the start winning device 15 is established, and the movable pieces 13 and 13 in the start winning device 15 are 13 is opened for a predetermined number of times for a predetermined time. In the vicinity of the normal symbol display 10, the normal symbol holding memory display 41 (see FIG. 3) having a display unit with four LEDs for displaying the number of memorized effective passing spheres that have passed through the gate 32, that is, the starting passing memorized number. ) Is provided. Every time there is a pachinko ball passing through the gate 32, the stored data of the start passing memory is incremented by 1, and the normal symbol holding memory display 41 increments the LED to be lit by 1. Then, every time the variable display on the normal symbol display 10 is started, the stored data of the start passage memory is decreased by 1, and the LED to be lit is decreased by 1.

  The game board 6 is provided with a plurality of normal winning ports including a first normal winning port 29 and a second normal winning port 30 as a winning area of a winning device that accepts a pachinko ball and allows winning. The winning of the pachinko ball to the first normal winning opening 29 is detected by the first winning opening switch 29a. The winning of the pachinko ball in the second normal winning opening 30 is detected by the second winning opening switch 30a. The first starting port 15a, the second starting port 15b, and the big winning port also constitute a winning area of the winning device that accepts a pachinko ball and allows winning. In addition, decorative light emitting portions 25L and 25R in which decorative LEDs 25a blinking and displayed during the game are provided around the left and right of the game area 7, and an out port 26 for collecting pachinko balls that have not won a prize is provided at the bottom. There is.

  Two speakers 27L and 27R that emit sound effects are provided at the left and right upper portions outside the game area 7, and two speakers 27a and 27b that emit sound effects are provided at the left and right lower portions. In the following description, the speakers 27L, 27R, 27a, and 27b may be collectively referred to as speakers 27.

  On the outer periphery of the game area 7, a top lamp module 530 in which various LEDs such as a rotating body LED are incorporated, a left light emitting unit 28L in which a left frame LED 28b (see FIG. 3) is incorporated, and a right frame LED 28c (see FIG. 3). ) Is built in. Further, a decoration LED is installed around each structure (such as a big prize opening) in the game area 7. The LED for the rotating body, the left frame LED 28b, the right frame LED 28c, and the decoration LED are examples of the decoration light emitter provided in the pachinko machine 1.

  In this example, a prize ball LED 51 that is lit during award ball payout is provided at a predetermined position of the left light emitting unit 28L, and a ball break LED 52 that is lit when a supply ball is cut is provided at a predetermined position of the right frame LED 28c. Is provided.

  Various light emitting means such as prize ball LED 51, ball-out LED 52, decoration LED 25 a, left frame LED 28 b, right frame LED 28 c, and each LED in the top lamp module 530 are based on the effect control command output from the main board 31. Lighting control (LED control) is performed based on the serial signal output from the computer 81. In addition, sound generation control (sound control) from the speakers 27L, 27R, 27a, and 27b is also performed by the effect control microcomputer 81.

  A pachinko ball launched from a hitting ball launching device (not shown) by operating the hitting operation handle 5 of the player enters a game area 7 through a hitting guide rail (not shown), and then a game standing on the game area 7. While coming into contact with the nail and changing the course, the game area 7 is lowered. When a pachinko ball enters the first start port 15a and is detected by the first start port switch 14a, or enters the second start port 15b and is detected by the second start port switch 14b, a special symbol variation display is displayed. If it can be started, the special symbol on the special symbol display 8 starts to be displayed in a variable manner. If the special symbol variable display is not ready to start, the number of reserved memories is increased by one.

  The variation display of the special symbol on the special symbol display 8 stops when the variation display time set every time the variation display is performed. If the special symbol (stop symbol) at the time of stoppage is a jackpot symbol (also referred to as a jackpot display result) as a specific display result, it will be a jackpot and the game will shift to a jackpot gaming state. In the big hit gaming state, the special variable winning ball apparatus 20 is released until a predetermined time elapses or a predetermined number (for example, ten) of pachinko balls wins. Then, if the pachinko ball wins the V winning area while the special variable winning ball apparatus 20 is opened and is detected by the count switch 23, a continuation right is generated and the special variable winning ball apparatus 20 is opened again. The generation of the continuation right is permitted with a predetermined number of times such as 15 rounds as an upper limit value. Such control is called repeated continuation control. In the repeated continuation control, a state in which the special variable winning ball apparatus 20 is opened is called a round.

  When the special symbol on the special symbol display 8 at the time of stoppage is a predetermined special big hit symbol (probability variable big hit symbol) of the big hit symbols, the probability that the big hit is determined after the big hit gaming state (big hit probability) ) Becomes a more advantageous state for the player, a probability variation state (hereinafter referred to as a probability variation state) that becomes higher than the normal gaming state, which is a normal state different from the big hit gaming state. Hereinafter, the probability variation state is also referred to as a high probability state (sometimes abbreviated as a high probability state). Further, the non-probability change state is also referred to as a low probability state (sometimes abbreviated as a low probability state).

  In addition, when the display result of the special symbol when the variable display on the special symbol display 8 is stopped is the probability variation big hit symbol, the variable time is reduced after the big hit gaming state, and the control is performed for a predetermined period of time. The Compared to the normal gaming state, the time-short state is a variation display time of each of the special symbol display 8, the variation display device 9, and the normal symbol display 10 (the time from the start of variation to the time when the display result is derived and displayed). ) Is a control state in which display results are derived and displayed at an early stage. Further, during the time-short state, the probability that the stop symbol in the normal symbol display 10 becomes a winning symbol is increased, and the opening time of the movable pieces 13 and 13 of the start winning device 15 is lengthened and the number of times of opening is increased. . During the time-short state, since the display time of the symbol variation is shortened, the number of reserved memories to be described later is digested early, and the start winning that occurs exceeding the upper limit (for example, “4”) of the number of reserved memories becomes invalid. Since it is easy to derive and display the jackpot display result early in the short term, it is easy to derive and display the jackpot display result early, so the display result of the variable display is likely to become the display result of the jackpot symbol from a time efficient viewpoint It becomes a gaming state advantageous to the player. As described above, in the case of the probability variation big hit A, the high probability state and the short time state are controlled in a predetermined period after the end of the big hit gaming state. The short time state over a predetermined period after the end of the jackpot gaming state is the earlier, until the next jackpot gaming state occurs or until the special symbols and decorative symbols are displayed a predetermined number of times (100 times). Continue until either condition is met.

  Also, when considering the payout of pachinko balls according to the winning, the time-short state is shorter than the non-time-short state and the normal symbol variation display time is shortened, and the stop symbol in the normal symbol display 10 becomes a winning symbol. The probability is increased, the opening time of the movable pieces 13 and 13 of the start winning device 15 at the time of winning is lengthened, and the number of times of opening the movable pieces 13 and 13 of the starting winning device 15 at the time of hitting is increased. Based on this, the movable pieces 13 and 13 of the start winning device 15 are likely to be in an open state as compared with the normal gaming state. Accordingly, in the short-time state, it is easy to generate a prize (including both a case where the start prize is valid and a case where the prize is invalid) in the second start port 15b, so the number of pachinko balls ( The ratio of the number of pachinko balls (the number of balls to be paid out) to be paid out as winning balls according to the winning is greater than the number of hitting balls) as compared to the normal gaming state. In general, the ratio of the number of paid-out balls for winning a prize to the number of shot balls is called “base”. For example, when there are 40 payout balls with respect to 100 shot balls, the base is 40 (%). In the case of this embodiment, for example, a time-short state having a higher base than a non-time-short state such as a normal gaming state is called a high base state, and conversely, a base game state having a lower base compared to such a high base state. Such a non-short-time state is called a low base state.

  In this way, the ratio of the number of award balls paid out by winning a prize to the number of balls launched is generally called “base”, but the maximum number of pachinko balls fired per unit time such as 1 minute is limited to a certain number. ing. For this reason, the “base” can also be indicated by a total value of the number of winning balls paid out by winning a plurality of winning openings provided in the game area in a unit time. For example, assuming that the maximum number of pachinko balls fired per unit time is 100, the total number of award balls paid out by winning in a unit time matches the general “base” value. Based on such relevance, in the present embodiment, each of the first start port 15a, the second start port 15b, the first normal winning port 29, and the second normal winning port 30 is an abnormality monitoring target winning port, A total value of the number of paid-out balls of the winning ball due to the winning of the abnormality monitoring target winning opening is called a base, and is used as an object of abnormality monitoring regarding winning.

  Whether the probability variation state (high probability state) or the non-probability variation state (low probability state) is determined based on whether or not the probability variation flag, which is a flag set in the probability variation state, is set. . Whether the time-short state (high base state) or the non-time-short state (low base state) is determined is determined based on whether or not the time-short flag, which is a flag set in the time-short state, is set. Is done.

  In addition, in the state that is not controlled to the above-mentioned time-short state, every time the number of special symbols on-hold storage exceeds a predetermined number, the memory that controls the memory variation shortened state that shortens the variation display time of the special symbol and the decorative symbol Variation shortening control is performed. The memory fluctuation shortening control ends when the number of reserved symbols for special symbols is less than a predetermined number. Therefore, even in a state where the time-short state is not controlled, there is a case where the variation display time of the special symbol and the decorative symbol is shortened.

  The decorative symbols that are variably displayed in the variable display device 9 are variably displayed in a predetermined relationship with the special symbol variation display in order to enhance the decoration effect of the special symbol variation display in the special symbol display 8. It is a symbol with a special meaning. The predetermined relationship for such symbols includes, for example, the relationship in which the decorative symbol variation display starts when the special symbol variation display is started, and the special symbol display result at the end of the special symbol variation display. This includes a relationship in which the decorative symbol display result is derived and displayed and the decorative symbol variation display is terminated. When the special symbol display 8 derives and displays a predetermined jackpot symbol as a display result, the variable display device 9 derives and displays a combination of the jackpot symbol with left, middle and right symbols as a display result. The Such a display result of the jackpot symbol by the special symbol and the display result of the combination of the jackpot symbol by the decoration symbol are referred to as a jackpot display result.

  The special symbol display 8 and the fluctuation display device 9 have a correspondence relationship as described above, and therefore, in the following description, these may be collectively referred to as a fluctuation display unit.

  Next, the reach display mode (reach) will be described. The reach display mode (reach) in the present embodiment means that the symbols that have not been stopped when the stopped symbols constitute a part of the jackpot symbol, and that all or This is a state where some symbols are synchronously displayed while constituting all or part of the jackpot symbol.

  For example, in the variable display device 9, an effective line (one effective line in the case of this embodiment) that becomes a big hit when the symbol stops is determined in advance, and a part of the display area on the effective line is preliminarily set. A state in which the variable display is performed in the display area on the active line that has not been stopped when the predetermined symbol is stopped (for example, among the left, middle, and right variable display areas in the variable display device 9) The left and right display areas are stopped and the same display is still displayed, and the middle display area is still in the variable display mode), and all or part of the display area on the active line A state in which all or a part of the jackpot symbol is configured and displayed in a synchronized manner (for example, all the left, middle, and right display areas in the variation display device 9 are displayed in a varying manner and are always the same. The state) variable display in a state where the handle is aligned is made that reach the display mode or reach.

  In addition, during the reach, an unusual effect may be performed by display (variable display device 9), LED, or sound. This production is called reach production. Further, in the case of reach, a character (an effect display imitating a person or the like, which is different from a design (decoration design or the like)) or a display mode (for example, a color or the like) of the background image of the variable display device 9 is displayed. ) May change. This change in character display and background display mode is called reach effect display. In addition, some reach is set so that when it appears, a big hit is likely to occur compared to a normal reach. Such special (specific) reach is called super reach.

  Further, for the variable display device 9, there may be a jackpot notice effect such as a pseudo-ream that notifies that there is a possibility of a big hit in the variable display that triggers the occurrence of the big hit.

  In this embodiment, as a big hit, a plurality of types of big hits such as a normal big hit C and a probable big hit A are provided as will be described later. In the following description, when “big hit” is simply indicated without specifying the types of big hits, it is a case where these multiple types of big hits are representatively shown.

  Normally, the big hit C is a big hit (non-probable big hit) that becomes a low probability state and a low base state because it does not become a probable change state after the end of the big hit gaming state and does not become a short-time state. Such a state with a low probability state and a low base state is called a low probability low base state. The probability variation jackpot A is a jackpot that becomes a probability variation state after the end of the jackpot gaming state and is in a high probability state in which the time is short for a predetermined period and in a high base state. Such a state with a high probability state and a high base state is referred to as a highly accurate high base state. After the probability variation big hit, when the predetermined period elapses, the time reduction state ends, and the state becomes a high probability state and a low base state. Such a state having a high probability state and a low base state is referred to as a high probability low base state.

  The random number circuit is a hardware circuit that is used to generate a random number for determination to determine whether or not to win a jackpot based on the display result of the variation display of the special symbol and the decorative symbol. The random number circuit updates numerical data in accordance with a set update rule within a numerical range in which an initial value (for example, 0) and an upper limit value (for example, 65535) are set, and at random timing. Based on the fact that the start winning time generated is the time of reading (extracting) the numerical data, it has a random number generation function in which the numerical data to be read becomes a random value.

It is determined whether or not to make a jackpot display result as a display result, that is, whether or not to make a jackpot. When it is determined that the game is a big hit, the gaming state is shifted to a big hit gaming state as a specific gaming state advantageous to the player. The determination as to whether or not to win is actually executed based on the random number value extracted at the time of starting winning at the start of the variation display of the special symbol and the decorative symbol. Whether the random number generated by the random number circuit is a big hit, such as a random number for probability variation determination for determining whether or not to make a probability variation, and a random number for variation pattern determination for determining a variation pattern of a special symbol. It may be used as a random number for determination other than determination.

  The clock circuit outputs a system clock signal to the CPU 56, and outputs a reference clock signal CLK having a predetermined period generated by dividing the system clock signal to each random number circuit. When a low level signal is input for a certain period, the reset controller outputs a predetermined initialization signal to the CPU 56 and each random number circuit to reset the game control microcomputer 156 as a system.

  The effect control board 80 receives an effect control command from the game control microcomputer 156 via the relay board 77, and controls the display of the effect display on the variable display device 9 and the effect that becomes the game related sound in the present invention. Electric component control means such as an effect control microcomputer 81 for controlling the output of the sound effect (effect sound) related to is mounted.

  Here, the configuration and operation of each switching power supply used for the power supply board 960 of the present embodiment will be described below.

  As shown in FIG. 5, the first switching power supply 961 mounted on the power supply substrate 960 is tuned by an AC / DC conversion circuit and an AC / DC conversion circuit that outputs an inverted wave by alternating current. A switching regulator circuit (IC) 961a that generates a 34V DC current (VSL1) from the measured DC waveform, and a switching regulator circuit (12) that generates a 12V DC current (VDD1) from the DC waveform that has been rectified by the AC / DC converter circuit. IC) 961b, and a switching regulator circuit (IC) 961c for generating a DC current (VCC1) of 5 V from the DC waveform tuned by the AC / DC conversion circuit.

  Further, as shown in FIG. 5, the second switching power supply 962 mounted on the power supply board 960 is also adjusted by an AC / DC conversion circuit and an AC / DC conversion circuit that outputs an inverted wave by alternating current to direct current. Switching regulator circuit (IC) 962a that generates a 34V direct current (VSL2) from the waved direct current waveform, and a switching regulator that generates a 12V direct current (VDD2) from the direct current waveform rectified by the AC / DC converter circuit A circuit (IC) 962b and a switching regulator circuit (IC) 962c that generates a DC current (VCC2) of 5 V from a DC waveform tuned by an AC / DC conversion circuit are incorporated.

  Each DC current (VSL1, VDD1, VCC1) output from the first switching power supply 961 is, as shown in FIGS. 3 and 5, the main board 31 that controls the game in the pachinko gaming machine 1, the payout control It is supplied to a board 37, a launch control board (not shown) for controlling the launch of the game ball from the hitting ball launcher by operating the hitting operation handle 5, and various switches and sensors connected to the input circuit 58 of the main board 31. The

  On the other hand, each direct current (VSL2, VDD2, VCC2) output from the second switching power supply 962 is not a control for playing a game in the pachinko gaming machine 1, as shown in FIG. 3 and FIG. Effect control board 80, variable display device 9, decoration LED 25a controlled by effect control board 80, left frame LED 28b, right frame LED 28c, each LED such as sky lamp module 530, and a not-shown accessory (gimmick) Is supplied to the operation button 516 and the operation lever 600 for accepting the operation related to the motor, the solenoid, and the production for operating the camera.

  As for 12V VDD2 output from the second switching power supply 962, as shown in FIGS. 3 and 5, the solenoids 16, 21, 21a provided on the game board 6 connected to the main board 31 are provided. The LED is also supplied to each display unit connected to the main board 31.

  That is, the first switching power supply 961 serving as the first switching regulator circuit of the present invention includes various switches and sensors connected to the main board 31 serving as detection means of the present invention, and ON of these various switches and sensors. A second switching power supply 962 that supplies DC power of a predetermined voltage to the main board 31 having the input circuit 58 for detecting the state and serves as the second switching regulator circuit of the present invention is connected to the effect control board 80. In addition, direct current power of a predetermined voltage is supplied to the effect control board 80 serving as the effect means of the present invention that performs effects related to the game using the devices such as LEDs.

  In this embodiment, the solenoids 16, 21, 21 a, which consume more power than switches, sensors, etc., and the LEDs used for each display connected to the main board 31 will be described later. As described above, by supplying VDD2 from the second switching power supply 962 having a high oscillation frequency, the power supplied from the first switching power supply 961 having a low frequency is reduced, so that the first switching power supply 961 can also be reduced in size. However, the present invention is not limited to this, and the first switching power supply 961 is also applied to the solenoids 16, 21, 21 a connected to the main board 31, and the LEDs used in the respective displays. It is also possible to supply VDD1 output from

  A fuse is provided on each DC power supply line output from the first switching power supply 961 and the second switching power supply 962 as shown in FIG.

  Next, regarding the difference between the switching regulator circuits (IC) used for the first switching power supply 961 and the second switching power supply 962, examples of the switching regulator circuits (IC) 961b and 962b that generate a 12V power supply are shown in FIG. Explained.

  The switching regulator circuit (IC) 961b used for the first switching power supply 961 does not have an output voltage change terminal, so that a fixed voltage output type switching regulator circuit (IC) in which an input of an output voltage change signal is disabled. ), And outputs a 12 V DC current of maximum output X amps at the oscillation frequency f1.

  On the other hand, the switching regulator circuit (IC) 962b used for the second switching power supply 962 has a variable voltage output type switching regulator circuit (IC) that has an output voltage change terminal and can receive an output voltage change signal. Thus, a 12 V DC current having a maximum output Y ampere is output at the oscillation frequency f2.

  Thus, in this embodiment, a fixed voltage output type switching regulator circuit (IC) is used for the switching regulator circuit (IC) 961b that generates power to be supplied to the main board 31, each switch, sensor, and the like. In this way, for example, it is possible to reliably prevent an unauthorized operation of erroneously inputting the output voltage change signal to the output voltage change terminal and causing the main board 31, each switch, sensor, or the like to malfunction. It is like that.

  In addition, the maximum output Y ampere of the second switching power supply 962 is larger than the maximum output X ampere of the first switching power supply 961 and can supply a larger current than the first switching power supply 961, and the second The oscillation frequency f2 of the switching power supply 962 is higher than the oscillation frequency f1 of the first switching power supply 961, and the second switching power supply 962 has a smaller occupied volume per unit output than the first switching power supply 961.

  In other words, by increasing the oscillation frequency f, it is possible to reduce the capacity of the coil or capacitor required for charging / discharging the inverted rectified current cut out by switching. Therefore, the occupied volume per unit output of the switching power supply is reduced.

  On the other hand, since the first switching power supply 961 has an oscillation frequency f1 lower than the oscillation frequency f2 of the second switching power supply 962, it is necessary to use a relatively large capacity as a coil or a capacitor. Although the occupied volume is large, the generation of noise due to switching is less than that of the second switching power supply 962, and the direct current VDD1 with less power supply noise can be supplied.

  That is, VDD1 supplied from the first switching power supply 961 is power supplied from a power supply with a large occupied volume per unit output but with low power supply noise, and VDD2 supplied from the second switching power supply 962 is unit output. Since power is supplied from a power supply with a small occupied volume but power supply noise is large, VDD1 supplied from the first switching power supply 961 is connected to the main board 31 and the input circuit 58 of the main board 31. By supplying these switches and sensors, the main board 31 that controls these games, and detection means for detecting that a state advantageous to the player in the game has occurred and that a predetermined state relating to fraud has occurred The noise resistance of the parts indispensable to the game, such as, is greatly reduced by the power supply noise of the first switching power supply 961 In addition to these parts that are indispensable to the game, the parts related to effects, etc., and solenoids and LEDs that consume relatively large power, are reduced in size by increasing the oscillation frequency. By supplying VDD2 output from the 2-switching power supply 962, the volume occupied by the power supply is reduced as compared to the case where f1 which is a low frequency is used as both power supplies.

  In the above description, the switching regulator circuits (IC) 961b and 962b have been described as an example, but the same applies to the switching regulator circuits (IC) 961a and 962a as well as the switching regulator circuits (IC) 961c and 962c.

  Next, the relationship between the switching regulator circuit (IC) and the fuse will be briefly described.

  As shown in FIG. 8, each switching regulator circuit (IC) of the present embodiment incorporates a well-known overcurrent prevention circuit, and an overcurrent is output due to a short circuit or the like. When the operation is stopped, the output is temporarily stopped, and when the operation of the overcurrent prevention circuit stops due to the stoppage of the output, the current is output again (hiccup state), so that the overcurrent is continuously output. This prevents the switching regulator circuit (IC) from being damaged.

  In the present embodiment, as described above, the fuses are provided in the power supply lines. However, as the capacities of these fuses, the fuses provided in the power supply line from the second switching power supply 962 are the same as in the normal case. , If the maximum output current of the corresponding switching regulator circuit (IC) is approximately equal to the maximum output current of the switching regulator circuit (IC) is 5 amperes, The fuse provided on the power supply line from the first switching power supply 961 is smaller than the maximum output current of the corresponding switching regulator circuit (IC). For example, the maximum output current of the switching regulator circuit (IC) is 3 amperes. If so, the one of 1 amp is used.

  In this way, as a fuse of the power supply line from the first switching power supply 961, a fuse of Z ampere smaller than the maximum output current X ampere of the switching regulator circuit (IC) is used, so that the power supply line is short-circuited. (Short circuit fraud) can be prevented.

  Specifically, as shown in FIG. 8A, when the power supply line is improperly short-circuited, the switching regulator circuit (for example, the switching regulator circuit (IC) 961b) is protected by an overcurrent prevention circuit. Even if power is output from the switching regulator circuit, the fuse is blown by the output of overcurrent due to a short circuit. Is prevented from being supplied to each sensor, switch, etc., so that it is avoided that the switch, sensor, etc., which is set to the reverse logic due to the power interruption due to the operation of the overcurrent prevention circuit, is erroneously determined to be in the ON state. Therefore, fraud (short circuit fraud) caused by short-circuiting the power supply line can be prevented.

  On the other hand, as shown in FIG. 8B, when a fuse having a Z amperage that is substantially equal to or larger than the maximum output current X amperage of the switching regulator circuit (IC) is used as a fuse of the power supply line, a short circuit occurs. By operating the overcurrent prevention circuit in the state where the fuse is not blown by the above hiccup state, the power output in the hiccup state is supplied to each sensor, switch, etc. Power failure due to operation of the overcurrent prevention circuit will erroneously determine that the switch or sensor, etc., which is set to reverse logic is in the ON state. In this case, however, as in this embodiment, each switch or sensor for detecting fraud (door opening switch 42, magnetic The sensor 43, the radio wave sensor 44, and the vibration sensor 45) are also reverse logic, so that it is detected that each switch or sensor for detecting fraud is in an ON state. Since it is notified by being displayed or the like, it is possible to detect fraud (short circuit fraud) by short-circuiting these power supply lines.

  That is, in this embodiment, by using a Z-ampere fuse smaller than the maximum output current X ampere of the switching regulator circuit (IC), fraud (short-circuit fraud) caused by short-circuiting the power supply line is positively prevented. In addition, even if the fuse is not blown out due to a short circuit, each switch or sensor (door open switch 42, magnetic sensor 43, radio wave sensor 44, vibration sensor) for detecting fraud connected to these power supply lines is detected. By setting the detection logic of the sensor 45) to the reverse logic, it is possible to detect and report fraud (short circuit fraud).

  As described above, according to the present embodiment, each switch, sensor, main board 31 (input circuit 58), or the like serving as the detection means of the present invention is supplied from the first switching power supply that performs switching at a lower frequency than the second switching power supply. While power with low power supply noise is supplied, the various solenoids and LEDs that are the production means of the present invention and the production control board 80 that controls the operation of these various solenoids and LEDs are higher than the first switching power supply. By switching at a frequency, power is supplied from the second switching power supply, which can reduce the occupied volume as compared with the first switching power supply and can reduce the cost by reducing the size of the coil and the like. Switching power supply provided in the pachinko machine 1 without reducing the tolerance due to an increase in power supply noise It is possible to reduce the occupied volume.

  Further, according to this embodiment, since the first switching regulator circuit can output only the predetermined voltage, it is output from the switching regulator circuit like a switching regulator circuit capable of outputting a voltage other than the predetermined voltage. It is possible to prevent a fraud in which the detection unit malfunctions by changing the voltage.

  Further, according to the present embodiment, it is detected that the state of the detection target has occurred on the condition that the voltage equal to or lower than the specified value detected when the state of the detection target has not occurred becomes the predetermined voltage. Compared with the case where it does, the influence by power supply noise can be reduced.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above embodiment, the pachinko machine 1 is illustrated, but the present invention is not limited to this, and a slot machine for playing a game using a medal as a game medium, or a game medium is a game machine. The number of pachinko balls and medals enclosed and rented inside and the number of pachinko balls and medals awarded according to the winnings are added, while the number of pachinko balls and medals used in the game are subtracted. All of the value of points and points lent out in response to a loan request and the value of points and points awarded in response to winnings, without using the enclosed game machines, pachinko balls and medals It may be a gaming machine that stores as credits and can play a game using only the value stored as credits. In this case, these points, points, and the like correspond to game media, and credits become game value.

  Moreover, in the said Example, although the form which used two switching power supplies was illustrated, this invention is not limited to this, These switching power supplies are outside the 1st switching power supply of f1 with low transmission frequency, A plurality of switching power supplies such as f2, f3, etc. whose transmission frequency is higher than f1 may be provided, or a power supply circuit reduced in size by increasing the frequency of these switching power supplies is mounted on each substrate. You may make it disperse | distribute.
