Abstract

To provide a game machine capable of diversifying connection modes of an LED even when an LED driver of a constant current type is used.SOLUTION: A game machine has second wiring provided with "a current limit resistor" which makes current flowing in the second wiring smaller than a specified value, out of first wiring (a first LED) connected to a first terminal of an LED driver of constant current type and the second wiring (a second LED) connected to a second terminal. Thus, only current smaller than "large current (the specified value)" flows in the second terminal (the second wiring) even when the "large current" is flown to the first terminal in order to emit light of the first LED (in order to drive it), thereby breakage of the second LED can be prevented. As a result, it is possible to emit light of LEDs mutually different in drive current even when the LED driver of the constant current type is used.SELECTED DRAWING: Figure 10

Description

  The present invention relates to a gaming machine for playing a game using a game medium such as a game ball or a game medal.

For example, an effect indicating a possibility that a privilege is given to a player, an effect indicating a progress of a game, and the like are performed (Patent Document 1). As such an effect, in addition to an effect of displaying various images on a display unit such as a liquid crystal display, an effect of causing LEDs (light emitting diodes) to emit light in various modes is performed. In order to perform such an effect of causing the LED to emit light, an ordinary gaming machine includes an IC package (also referred to as an “LED driver” in this specification) in which an electronic circuit for emitting (driving) the LED is built. It is installed.

  As such LED drivers, there are a constant voltage type LED driver that applies a predetermined voltage to both ends of the LED, and a constant current type LED driver that supplies a constant current to the LED. Among them, the constant current type LED driver can supply a constant current to the LED even when the power supply voltage fluctuates, so that the brightness of the LED can be stabilized as compared with the constant voltage type LED driver. .

The first special figure and the second special figure (hereinafter, collectively referred to as “special symbols” unless otherwise distinguished) are obtained by switching the lit LED among the nine LEDs in each display unit. The variable display is performed, and the stop display is performed by turning on a predetermined LED among the nine LEDs. In the pachinko machine 1 of the present embodiment, 200 kinds of big hit symbols (big hit symbols 101 to 300) and one kind of off symbol (off symbol 101) can be stopped and displayed as a first special figure, and as a second special figure. , 200 kinds of big hit symbols (big hit symbols 401 to 600) and one kind of off symbol (off symbol 401) can be stopped and displayed. These types of symbols can be identified by differences in the combinations of the LEDs that are turned on.

  The CPU 201 of the main control board 200 determines that the result of the special figure hit determination (hereinafter, also referred to as “the special figure hit determination for the first special figure”) based on the game ball entering the first starting port 24 is “big hit”. , The first special figure is stopped and displayed at any of the big hit symbols 101 to 300, and if the result of the special figure hit determination for the first special figure is “missing”, the first special figure is removed. The display is stopped at the symbol 101. If the result of the special figure hit determination (hereinafter also referred to as “special figure hit determination for the second special figure”) based on the game ball entering the second starting port 25 is “big hit”, The second special figure is stopped and displayed with any of the big hits 401 to 600, and when the result of the special figure hit determination for the second special figure is "missing", the second special figure is stopped and displayed with the missing special pattern 401.

  Then, when the CPU 201 of the main control board 200 stops and displays the special symbol (the first special symbol or the second special symbol) in either the big hit symbol or the off symbol, the symbol is stopped to fix the symbol that has been stopped and displayed. A display for maintaining the displayed state until a predetermined time elapses (hereinafter, also referred to as “confirmed display”) is performed. Hereinafter, the game from the start of the variable display to the final display of the special symbol, that is, the game until the result of one variable display is obtained is also referred to as “symbol variable game”.

  Here, the CPU 201 of the main control board 200 selects a change pattern of the special symbol change display (symbol change game) when performing the change display of the special symbol (the first special figure or the second special figure). The fluctuation pattern is the time (variation time) from when the special symbol starts to display the fluctuation to when it is stopped, and information (variation pattern ID) for identifying each fluctuation pattern from other fluctuation patterns is added. Have been. In the process of selecting a variation pattern, a “variation pattern selection table” in which a variation pattern selection random number is assigned to a plurality of variation patterns (variation pattern ID, variation time) is referred to. Then, a fluctuation pattern corresponding to the fluctuation pattern selection random number acquired as the first special figure reservation or the second special figure reservation is selected as the current fluctuation pattern. The special symbol is variably displayed based on the variance pattern thus selected.

  When starting the variation display of the special symbol, the CPU 201 of the main control board 200 transmits a variation pattern designation command indicating the variation pattern of the variation display to the sub-control board 220. As a result, the variation pattern of the special symbol variation display started this time is transmitted to the sub-control board 220. When the CPU 221 of the sub-control board 220 receives the variation pattern designation command, the CPU 221 recognizes the variation pattern of the special symbol variation display started this time based on the variation pattern designation command, and based on (corresponds to) the recognized variation pattern. An effect corresponding to the special symbol change display (symbol change game) in the effect pattern (hereinafter also referred to as “symbol change effect”) is executed.

  In the above-described process of selecting a variation pattern, instead of always referring to the same variation pattern selection table, a variation pattern selection table corresponding to various game progress situations is referenced. For example, the type of the special symbol (the first special figure or the second special figure), the currently set game state, the result of the special figure hit determination, the stored first special figure hold and the second special figure hold The variation pattern selection table corresponding to the number or the like is referred to. By doing so, it is possible to select a variation pattern corresponding to various game progress situations, and, consequently, the CPU 221 of the sub-control board 220 can execute an effect with an effect pattern corresponding to various game progress situations.

  Further, when stopping the change display of the special symbol, the CPU 201 of the main control board 200 transmits a change stop command to the sub control board 220. When the CPU 221 of the sub control board 220 receives the change stop command, the timing at which the special symbol change display (symbol change game) ends is transmitted to the CPU 221 of the sub control board 220.

  Note that the special symbol can be regarded as “identification information”, and the CPU 201 of the main control board 200 that variably displays the special symbol can be regarded as “identification information display means”.

<Holding special symbols>
When the game ball enters the first starting port 24 or the second starting port 25, the special figure hit determination and the fluctuation display for the special symbol are performed as described above. The CPU 201 of the main control board 200 does not perform the game ball immediately after the ball enters the first starting port 24 or the second starting port 25, but stores the acquired judgment random number as a special symbol hold (special figure hold) in the RAM 203. Once.

  More specifically, when a game ball enters the first starting port 24, a judgment random number is acquired, and the acquired judgment random number is temporarily stored as a first special figure hold. Then, when a predetermined condition is satisfied, a special figure hit determination and a change display of the first special figure are performed for the stored first special figure reservation. Such first special figure reservation is stored with an upper limit of four. The storage number of the first special figure reservation (the first special figure reservation number) is displayed on the first special figure reservation display section 53 of the segment display section 50. That is, as shown in FIG. 4, two LEDs are arranged in the first special figure suspending display unit 53, and in the first special figure suspending display unit 53, both of the two LEDs are turned off. This means that the first special figure reservation number is 0, and that one LED is turned on to indicate that the first special figure reservation number is one, and that two LED are turned on. The first special figure reservation number is two, and one LED blinks to indicate that the first special figure reservation number is three, and the first LED is blinked by two LEDs. Indicates that the number of special figure reservations is four.

  Further, when the game ball enters the second starting port 25, a judgment random number is acquired, and the acquired judgment random number is temporarily stored as a second special figure hold. Then, when a predetermined condition is satisfied, a special figure hit determination and a change display of the second special figure are performed for the stored second special figure holding. Such second special figure reservations are also stored with an upper limit of four. The storage number of the second special figure reservation (the second special figure reservation number) is displayed on the second special figure reservation display unit 54 of the segment display unit 50. That is, as shown in FIG. 4, two LEDs are also arranged in the second special figure suspending display unit 54, and in the second special figure suspending display unit 54, both of the two LEDs are turned off. This indicates that the number of second special figure reservations is 0 and that one LED is lit, indicating that the second special figure reservation number is one, and that the two LEDs are lit. The second reserved special figure number is two, and one LED blinks to indicate that the second special figure reserved number is three, and the second LED is blinked to blink the second LED. Indicates that the number of special figure reservations is four.

  In the pachinko machine 1 of the present embodiment, during the variation display of any special symbol, during the confirmation display of any special symbol, or during the big hit game, even if the special figure hold is stored, Judgment and special symbol change display are not performed. Further, when a plurality of special figure reservations are stored, regardless of whether they are the first special figure reservation or the second special figure reservation, the special figure reservation for the first special figure reservation stored is stored. The hit determination and the special symbol change display are performed (they have a so-called special symbol sequential change function).

<Game state>
The CPU 201 of the main control board 200 determines, as the gaming state of the pachinko machine 1 of the present embodiment, “the gaming state related to the probability of being determined to be a big hit in the special figure hit determination” and “input of a gaming ball into the second starting port 25”. Game state related to ball frequency "is set as appropriate. Of these, as the "game state relating to the probability of being determined to be a big hit in the special figure hit determination", a "low probability state" or a "high probability state" is set. The “low-probability state” is a state in which the probability of being determined to be a big hit in the special figure hit determination is low (probability of about 1/100), and the “high-probability state” is determined to be a big hit in the special figure hit determination. Is a state with a high probability (approximately 1/10 probability).

  As the “game state related to the frequency of game balls entering the second starting port 25”, “non-electric support state” or “electric support state” is set. The “non-electric support state” is a state where the frequency of game balls entering the second starting port 25 is low, and the “electric support state” is a state where the frequency of game balls entering the second start port 25 is high. It is. By doing so, in the “non-electric support state”, the game ball is more likely to enter the first starting port 24 than the second starting port 25, and in the “electric support state”, the game ball is more second than the first starting port 24. A game ball easily enters the starting port 25. For this reason, in the “non-power support state”, the player can make the player make a left hit (aim to enter the first starting port 24), and in the “power support state”, the player makes a right-hand drive. Can be performed (aim to enter the second starting port 25).

  It should be noted that the segment display unit 50 is provided with an electric support display unit 58 that indicates that the above-described electric support state is being established. That is, as shown in FIG. 4, three LEDs are arranged in the electric support display unit 58, and during the electric support state, the three LEDs are turned on to indicate that the electric support state is in effect. Is shown to the player. Further, the segment display unit 50 is provided with a right-hand display unit 59 for urging the player to perform right-hand operation. During the power support state, the frequency of entering game balls into the second starting port 25 is high, and the second starting port 25 allows right-hit game balls to enter the ball. Is beneficial for the player. Therefore, during the power support state, the two LEDs arranged on the right-hand display unit 59 are turned on to prompt the player to perform right-hand.

<Big hit game>
When the first special figure or the second special figure is stopped and displayed with any of the big hit symbols, the CPU 201 of the main control board 200 performs a plurality of round games in which the first special winning opening 28 or the second special winning opening 35 is opened. Start a big hit game. As described above with reference to FIG. 2, the right-hit game ball can enter the first special winning opening 28 and the second special winning opening 35, so that the right-hitting is performed during the big hit game. Become.

  As shown in FIG. 5, in the pachinko machine 1 of the present embodiment, a big hit game of “V short” and a big hit game of “V long” can be executed as the big hit game. More specifically, as shown in FIG. 5A, when the first special figure is stopped and displayed with the big hit symbols 101 to 280 (when the first special figure is stopped and displayed with the big hit symbol, there is a 90% probability. ), When the big hit game of "V short" is performed and the first special figure is stopped and displayed with the big hit symbols 281 to 300 (when the first special figure is stopped and displayed with the big hit symbol), there is a 10% probability. ), A big hit game of “V long” is performed. Also, as shown in FIG. 5B, when the second special figure is stopped and displayed with the big hit symbols 401 to 600 (when the second special figure is stopped and displayed with the big hit symbols, there is a 100% probability). , "V Long" big hit game is performed.

  In the pachinko machine 1 of the present embodiment, two round games are performed regardless of whether the “V short” big hit game or the “V long” big hit game is performed, and the first round game is performed. Then, the first special winning opening 28 is in an open state, and in the second round game, the second special winning opening 35 is in an open state. However, the big hit game of “V short” and the big hit game of “V long” have different “possibility of entering a game ball into the specific opening 38”. In other words, in the "V short" big hit game and the "V long" big hit game, the first big winning opening 28 is opened for 10 seconds (or until four game balls enter) in the first round game. However, the opening time of the second special winning opening 35 in the second round game is different from each other. Specifically, in the big hit game of “V short”, since the opening time of the second big winning opening 35 in the second round game is 0.2 seconds, the game ball is difficult to enter the specific opening 38, and “V short” In the “long” jackpot game, since the opening time of the second big winning opening 35 in the second round game is 10 seconds (or until four gaming balls enter), the gaming ball enters the specific opening 38. Easy to ball.

  Then, as shown in FIG. 5C, when the game ball enters the specific port 38 during the "V short" big hit game, the game state after the big hit game ends is "high probability state and power support state". (High probability / electric support state) ", and if the game ball does not enter the specific port 38 during the" V short "big hit game, the game state after the big hit game ends is" low probability state and Non-electric support state (low probability, non-electric support state) ".

  Also, when a game ball enters the specific port 38 during the “V Long” big hit game, the game state after the end of the big hit game is set to “high probability / electric support state”, and the “V long” big hit If the game ball does not enter the specific port 38 during the game, the game state after the end of the big hit game is set to “low probability state and electric support state (low probability / electric support state)”.

  The "high-probability / electric support state" continues until the next big hit game is played, and the "low-probability / electric support state" continues until the symbol change game is performed 45 times. If done, terminate.)

  Here, when starting the big hit game, the CPU 201 of the main control board 200 transmits a big hit game start command indicating that the big hit game is started to the sub control board 220. Upon receiving the big hit game start command, the CPU 221 of the sub-control board 220 executes a big hit game effect corresponding to the big hit game.

  Note that the first special winning opening 28 and the second special winning opening 35 can also be regarded as a "variable winning opening", and the open state of the first special winning opening 28 and the second special winning opening 35 is set to a "ball entry possible state". , And the jackpot game can be caught as "specific game". In addition, the CPU 201 of the main control board 200 that executes the big hit game (specific game) in which the first special winning opening 28 and the second special winning opening 35 (variable entrance opening) are in an open state (a possible state of entering the ball), It can also be considered as “specific game execution means”.

<Various display of ordinary symbols, game per ordinary symbol, hold of ordinary symbols>
As described above with reference to FIG. 2, the normal symbol operation gate 27 allows a right-hit game ball to pass therethrough. When a right-hitting game ball passes through the normal symbol operation gate 27 and the game ball is detected by the gate sensor 27s, the CPU 201 of the main control board 200 determines a predetermined judgment random number (a later-described common figure hit judgment random number). Is obtained, and a general figure hit determination is made to determine whether it is a general figure hit or a miss based on the determination random number. Then, based on the result of the ordinary symbol hit determination, the normal symbol is displayed in a fluctuating manner and then stopped and displayed. As shown in FIG. 4, the segment display unit 50 is provided with a general-purpose display unit 56 for displaying a normal symbol, and the general-purpose display unit 56 includes two LEDs. The ordinary symbol is variably displayed by switching the LED to be lit among the two LEDs on the general symbol display unit 56, and is stopped and displayed by turning on a predetermined LED among the two LEDs. In the pachinko machine 1 of the present embodiment, two types of symbols are stopped as a normal symbol, a symbol per ordinary symbol in which the left LED is turned on and a non-normal symbol in which the right LED is turned on. Can be displayed. If the result of the normal hit determination is a normal hit, the normal symbol is stopped and displayed with the normal hit symbol, and if the result of the normal hit determination is a non-normal hit, the normal symbol is stopped and displayed with the non-normal hit symbol Is done. In this manner, when the normal symbol is hit and stopped and displayed with the off symbol, a display (fixed display) for maintaining the stopped and displayed state of the symbol until a predetermined time elapses is performed in order to fix the symbol that has been stopped and displayed. Then, when the normal symbol is stopped and displayed with the symbol per ordinary symbol, a game per ordinary symbol in which the second starting port 25 is in the open state and then in the closed state is performed.

  The non-electric support state and the electric support state described above are set by differentiating the manner of judging a normal figure, the manner of displaying a normal symbol in a fluctuating manner, and the manner of a game of a regular figure. In other words, the probability of being determined to be a perpetual figure in the perpetual figure perception is 1/100 in the non-power support state and 99/100 in the power support state. In addition, as the fluctuation time of the normal symbol, a long time is easily selected in the non-electric support state (one of 1000 ms, 2000 msec, and 3000 msec is equally selected), and a short time is selected in the electric support state. (Either 1000 ms, 1252 ms, or 1500 ms is equally selected). In the non-power support state, a non-power support game is performed in which the second starting port 25 is opened for a short time (16 msec × 1 time). A game per ordinary drawing in which the starting port 25 is open for a long time (840 msec × 2 times) is performed. As a result, during the non-power support state, the frequency at which the second starting port 25 is opened is reduced, and the frequency of game balls entering the second starting port 25 is also reduced. On the other hand, during the electric support state, the frequency at which the second starting port 25 is opened increases, and the frequency of game balls entering the second starting port 25 increases.

  When the game ball passes through the ordinary symbol operation gate 27, the normal symbol hit determination and the variation display of the ordinary symbol are performed, but these ordinary symbol hit determination and the variation display are performed immediately after the game ball passes the ordinary symbol activation gate 27. Rather than being performed, the obtained judgment random number is temporarily stored as a normal drawing hold. Then, when a predetermined condition is satisfied, a general symbol hit determination and a normal symbol variation display are performed based on the stored general symbol reservation. Such general reservations are also stored with an upper limit of four. The number of stored general-purpose drawings (number of general-purpose reservations) is displayed on the general-purpose display display unit 57 of the segment display unit 50. That is, as shown in FIG. 4, two LEDs are arranged in the general-purpose reserve display unit 57, and the general-purpose reserve display unit 57 turns off both of the two LEDs so that the general-purpose reserve display unit 57 turns off. It indicates that the reserved number is 0 and turns on one of the two LEDs to indicate that the reserved number is one. The number of reservations is two, the blinking of one LED indicates that the number of reservations is three, and the blinking of two LEDs indicates that the number of reservations is four. Indicates that there is. In the pachinko machine 1 according to the present embodiment, if the normal symbol is stored, if the normal symbol is not being displayed during the change display, the normal symbol is being confirmed, or the game is not being played per the ordinary symbol, the pachinko machine 1 is the earliest. The stored general figure holding related to the general figure holding and the fluctuation display of the normal symbol are performed.

<Display contents of effect display device 41>
In the pachinko machine 1 of the present embodiment, an effect of displaying various images on the effect display device 41 is performed in accordance with the progress of the game as described above. Processing for performing such an effect is mainly performed by the CPU 221 of the sub-control board 220. That is, the CPU 221 of the sub-control board 220 receives a command indicating the progress of the game (for example, the above-mentioned variation pattern designation command, big hit game start command, etc.) from the CPU 201 of the main control board 200, The progress is grasped, and an effect according to the progress of the game is performed.

  For example, when the CPU 221 of the sub-control board 220 receives the variation pattern designation command, it performs a symbol variation effect in accordance with the variation display (variation pattern) of the first special figure or the second special figure. In other words, in synchronism with the start timing of the fluctuation display (symbol fluctuation game) of the special symbol (the first special figure or the second special figure), the effect display device 41 starts the fluctuation display of the three identification symbols 41a, 41b, 41c. I do. After that, the variation of the identification symbols 41a, 41b, 41c is displayed in various modes until the variation time of the special symbol elapses. Then, the CPU 221 of the sub-control board 220 ends the symbol variation effect when receiving the variation stop command. That is, the fluctuation display of the identification symbols 41a, 41b, and 41c ends in synchronization with the end timing of the special symbol fluctuation display (stop display of the special symbol). In the pachinko machine 1 of the present embodiment, a design in which nine numbers from “1” to “9” are designed can be displayed as identification symbols.

  FIG. 6A conceptually illustrates a state in which three identification symbols 41a, 41b, and 41c are simultaneously displayed in a fluctuating manner. When a predetermined time has elapsed since the start of the variable display, for example, the left identification symbol 41a is first stopped and displayed, then the right identification symbol 41c is stopped and displayed, and finally the middle identification symbol 41b is stopped and displayed. The combination of the three identification symbols 41a, 41b, 41c stopped and displayed on the effect display device 41 is a special symbol (the first symbol) stopped and displayed on the first special figure display section 51 or the second special figure display section 52 described above. (The first special figure or the second special figure). For example, when the first special figure or the second special figure is stopped and displayed with the big hit symbol (that is, when the variation pattern selected when the result of the special figure hit determination is “big hit” is received), The three identification symbols 41a, 41b, and 41c of the effect display device 41 are stopped and displayed in a symbol combination (hereinafter, also referred to as a "double-eye") having the same symbol. In addition, when the first special figure or the second special figure is stopped and displayed with a deviated symbol (that is, when a variation pattern selected when the result of the special figure hit determination is “big hit” is received), The three identification symbols 41a, 41b, and 41c are stopped and displayed in a symbol combination that is not aligned with the same symbol (hereinafter, also referred to as a "ragged eye"). Note that the identification symbols 41a, 41b, and 41c that are stopped and displayed are in a state where they are stopped and displayed (determined and displayed) until the fixed symbol display time has elapsed.

  As described above, the special symbol displayed on the first special figure display unit 51 or the second special figure display unit 52 and the three identification symbols 41a, 41b, and 41c displayed on the effect display device 41 have different display contents. When the special symbols in the variable display are stopped and displayed, the three identification symbols 41a, 41b and 41c are also stopped and displayed. Moreover, as shown in FIG. 2, the effect display device 41 is provided at a position that is more conspicuous than the first special figure display unit 51 or the second special figure display unit 52 (segment display unit 50). Since the screen is large and the display content is easy to understand, it is normal for a player to play a game while viewing the screen of the effect display device 41. Therefore, as shown in FIG. 6B, for example, the left identification symbol 41 a that is first stopped and displayed on the display screen of the effect display device 41 and the right identification symbol 41 c that is subsequently stopped and displayed are the same symbol. If there is, the middle identification symbol 41b, which is finally stopped and displayed, also stops at the same symbol, and the player is prompted to change the identification symbol (design variation effect) by saying "may a big hit game be started?" ). As described above, the effect performed in a state in which the identification symbol excluding one identification symbol from the plurality of identification symbols is stopped at the same symbol (an aspect that can be a zigzag pattern) and the one identification symbol is variably displayed is “ It is called a “reach effect”, and it is possible to enhance the entertainment of the game by generating the reach effect.

  Also, at the lower part of the display screen of the effect display device 41, a first reserved display area 41d for indicating the first special figure reserved number, and a second reserved display area 41e for indicating the second special figure reserved number. Is set. In the pachinko machine 1 according to the present embodiment, the same number of the first special figure reservations (small circular symbols in the figure) as the first special figure reservation number is displayed in the first reservation display area 41d, so that the first special figure reservation number ( The upper limit number is 4), and the same number of “holding symbols” as the second special figure holding number (the upper limit number is 4) is displayed in the second holding display area 41e to indicate the second special figure holding number. Therefore, the example shown in FIG. 6 indicates that the first special figure reservation number is four and the second special figure reservation number is four. It should be noted that, of course, the number of holds indicated by the hold symbols displayed on the display screen of the effect display device 41 and the first special figure hold display section 53 and the second special figure hold display section 54 of the segment display section 50 are displayed. Matches the number of holds indicated.

<Lamp lighting effect>
In the pachinko machine 1 of the present embodiment, a “lamp lighting effect” for turning on the lamp 5 can be executed during the execution of the above-described symbol change effect, and whether the “lamp lighting effect” is executed or not is determined. The “reach expectation” and “big hit expectation” differ depending on the type. The “reach expectation” is a possibility that a reach effect is performed, and the “big hit expectation” is a possibility that a big hit is determined as a “big hit” (a possibility of a big hit game being performed). Such “reach expectation” and “big hit expectation” are set to be higher when the “lamp lighting effect” is performed than when the “lamp lighting effect” is not performed.

  In the “lamp lighting effect”, the “reach expectation” and the “big hit expectation” are suggested by the lighting color of the lamp 5. In detail, the “reach expectation” and “big hit expectation” when the “lamp lighting effect” is performed are the lowest when the lighting color of the lamp 5 is blue, the next lowest when the lighting color of the lamp 5 is green, and the red Is set to be highest.

  The “reach expectation” and the “big hit expectation” related to the “lamp lighting effect” are the execution probability of the “lamp lighting effect”, that is, the probability that the variation pattern corresponding to the “lamp lighting effect” is selected. This is realized by appropriately setting. In other words, the “lamp lighting effect” is configured to be executed when a variation pattern corresponding to the “lamp lighting effect” is selected, and the probability of selecting such a variation pattern is appropriately set. As a result, the above-described “reach expectation” and “big hit expectation” can be realized.

  For example, as shown in FIG. 7, when the result of the big hit determination is a big hit (or when a reach effect is performed), the “probability that a variation pattern in which the lamp lighting effect is not performed (the probability that the lamp lighting effect is not performed) is selected. )) Is set to the lowest, and the “probability of selecting a variation pattern for performing a lamp lighting effect lit in blue (probability of performing a lamp lighting effect lit in blue)” → “a lamp lighting effect lit in green” Probability of selecting a variation pattern to be selected (probability of performing a lamp lighting effect that lights up in green) ”, and increasing the order of“ probability of selecting a variation pattern that performs a lamp lighting effect of lighting up in red (lamp lighting that lights up in red) Is set to be highest. Conversely, when the result of the jackpot determination is out of order (or when the reach effect is not performed), the “probability that a fluctuation pattern in which the lamp lighting effect is not performed (the probability that the lamp lighting effect is not performed)” is the highest. It is set, "Probability of selecting a variation pattern for performing a lamp lighting effect lit in blue (probability of performing a lamp lighting effect illuminating in blue)" → "Selecting a variation pattern for performing a lamp lighting effect lit in green" Probability (probability of performing a lamp lighting effect that lights up in green) ”, and the probability of selecting a variation pattern that performs a lamp lighting effect of lighting up in red (probability of performing a lamp lighting effect that lights up in red) Is set to be the lowest.

C. LED control board:
The “lamp lighting effect” as described above is performed by the LED control board 300 controlling the light emission mode of the three LEDs provided inside the lamp 5. That is, a “red LED 71 that emits red light”, a “green LED 72 that emits green light”, and a “blue LED 73 that emits blue light” are provided inside the lamp 5, and a lamp lighting effect of lighting red is performed. In this case, the red LED 71 is illuminated, the green LED 72 is illuminated when a green lamp is lit, and the blue LED 73 is illuminated when a blue lamp is illuminated.

  In the above-described lamp lighting effect, not only the lighting color of the lamp 5 but also the brightness of the lamp 5 (the brightness of the LED) differs depending on the “big hit expectation (or reach expectation)”. That is, in the lamp lighting effect in which the "big hit expectation (or reach expectation)" is illuminated in red, the lamp 5 is turned on with the highest brightness (the red LED 71 emits light with the highest brightness), and the "big hit expectation ( Alternatively, in the lamp lighting effect in which “reach expectation degree” is illuminated to the next highest green, the lamp 5 is turned on at the next highest luminance (the green LED 72 emits light at the next highest luminance), and “big hit expectation degree (or reach expectation degree)” )), The lamp 5 is lit at the lowest luminance in the lamp lighting effect in which the blue LED is lit (the blue LED 73 emits light at the lowest luminance). In order to perform such a lamp lighting effect, in this embodiment, as the red LED 71, the green LED 72, and the blue LED 73, LEDs having different light emission luminances are adopted. That is, since the red LED 71, the green LED 72, and the blue LED 73 have different emission luminances, the drive currents (forward currents) are different from each other. Specifically, the driving current of the red LED 71 having the highest emission luminance is the largest (for example, 30 mA), the driving current of the green LED 72 having the next highest emission luminance is the next largest (for example, 20 mA), and the blue LED 73 having the lowest emission luminance. Is the smallest (for example, 10 mA).

  Hereinafter, the LED control board 300 of the present embodiment for emitting the red LED 71, the green LED 72, and the blue LED 73 will be described. First, as a preparation, the conventional LED control board 400 will be described.

C-1. Conventional LED control board 400:
FIG. 8 conceptually shows the configuration of a conventional LED control board 400. As shown in FIG. 8, a constant voltage type LED driver 401 is mounted on the LED control board 400, and a red LED 71, a green LED 72, and a blue LED 73 are connected to the LED driver 401. That is, the cathode side of the red LED 71 is connected to the output terminal O1 of the LED driver 401 via the wiring H1, and the cathode side of the green LED 72 is connected to the output terminal O2 of the LED driver 401 via the wiring H2. The cathode side of the blue LED 73 is connected to the output terminal O3 of the LED driver 401 via the wiring H3. The anodes of the red LED 71, the green LED 72, and the blue LED 73 are connected to the power supply V1. Since the LED driver 401 is of a constant voltage type, an electronic circuit for applying a constant and identical voltage to the output terminals O1 to O3 is mounted.

  The LED driver 401 causes a current to flow through the wiring H1 by making the voltage output to the output terminal O1 lower than the power supply V1, thereby causing the red LED 71 to emit light. Further, by making the voltage output to the output terminal O2 lower than the power supply V1, a current flows through the wiring H2, thereby causing the green LED 72 to emit light. Further, by making the voltage output to the output terminal O3 lower than the power supply V1, a current flows through the wiring H3, thereby causing the blue LED 73 to emit light. The LED driver 401 is naturally provided with various terminals in addition to the output terminals O1 to O3. For example, a terminal for inputting a lighting pattern designation command transmitted from the sub control board 220 is also provided. Have been.

  If the LED driver 401 turns on the lamp 5 in red (receives a lighting pattern designation command indicating that the lamp 5 is turned on in red), the LED driver 401 causes the red LED 71 to emit light by flowing a current through the wiring H1. When the lamp 5 is turned on in green (when a lighting pattern designating command indicating that the lamp 5 is turned on in green is received), a current is passed through the wiring H2 to cause the green LED 72 to emit light and the lamp 5 to turn blue. When the LED is turned on (when a lighting pattern designation command indicating that the lamp 5 is turned on in blue is received), the blue LED 73 is caused to emit light by flowing a current through the wiring H3.

  As described above, in the related art, when the red LED 71, the green LED 72, and the blue LED 73 having different driving currents emit light, a constant voltage LED driver (here, the LED driver 401) is used. If the LED driver is of a constant current type instead of a constant voltage type, it is natural (as is well known) that a plurality of output terminals (here, terminals corresponding to the output terminals O1 to O3) are identical to each other. This is because a constant current flows in the LED, so that LEDs having different driving currents cannot emit light. For example, when a current of 30 mA is applied to an output terminal (a terminal corresponding to the output terminal O1) to emit (drive) the red LED 71, a green LED 72 and a blue LED 73 (terminals corresponding to the output terminals O2 and O3) are applied. Also, a current of 30 mA flows, and the green LED 72 and the blue LED 73 may be damaged. Conversely, when a current of 10 mA flows through the output terminal (terminal corresponding to the output terminal O3) to cause the blue LED 73 to emit light, a 10 mA current flows through the red LED 71 and the green LED 72 (terminals corresponding to the output terminals O1 and O2). Only flows, the red LED 71 and the green LED 72 do not emit light, or the luminance of the red LED 71 and the green LED 72 becomes insufficient.

  On the other hand, in the case of the constant voltage type LED driver 401, since the same and constant voltage is applied to the output terminals O1 to O3, the resistors R1 to R3 are provided as shown in FIG. This allows the current (drive current) corresponding to the red LED 71, the green LED 72, and the blue LED 73 to flow (adjust). That is, a resistor R1 having a resistance value such that a current of 30 mA flows is provided on the wiring H1 to which the red LED 71 is connected, and a resistor R1 having a resistance of 20 mA is provided for the wiring H2 to which the green LED 72 is connected. A resistor R2 having a resistance value such that a current of 10 mA flows is provided on the wiring H3 to which the blue LED 73 is connected.

  As described above, in the related art, when the red LED 71, the green LED 72, and the blue LED 73 having different driving currents emit light, a constant-voltage LED driver (here, a constant-voltage LED driver 401) has to be used. Did not get. However, when the voltage of the power supply V1 fluctuates, the current flowing through the wirings H1 to H3 also fluctuates, as a matter of course (as is well known). There is a problem that the brightness of the blue LED 73 cannot be stabilized.

  Therefore, in the pachinko machine 1 of this embodiment, even when the red LED 71, the green LED 72, and the blue LED 73 having different driving currents emit light, a constant current type LED driver is used instead of a constant voltage type LED driver. . In other words, if a constant current type LED driver is used, it is normally impossible to cause the red LED 71, the green LED 72, and the blue LED 73 having different driving currents to emit light as described above. However, the pachinko machine 1 of the present embodiment makes this possible. Hereinafter, the LED control board 300 of the present embodiment that enables this will be described.

C-2. LED control board 300 of the present embodiment:
FIG. 9 conceptually shows the configuration of the LED control board 300 of the present embodiment. As shown in FIG. 9, an LED driver 301 of a constant current type instead of a constant voltage type is mounted on the LED control board 300 of the present embodiment. The output terminal O1 of the constant current type LED driver 301 is connected to the cathode side of the red LED 71 via the wiring H11, and the output terminal O2 is connected to the cathode side of the green LED 72 via the wiring H12. The cathode side of the blue LED 73 is connected to the terminal O3 via the wiring H13.

  Here, as shown in FIG. 9, a resistor R10 is provided on the wiring H2, and a resistor R11 is provided on the wiring H3. If there is), it is not provided in the constant current type LED driver 301. The reason will be described with reference to FIG.

  FIG. 10 is an explanatory diagram showing circuits around the output terminals O1 to O3 of the constant current type LED driver 301. As shown in FIG. 10, the constant current type LED driver 301 includes electronic circuits E1 to E3 having the same circuit configuration. These electronic circuits E1 to E3 have a function of flowing a constant current to the output terminals O1 to O3.

  That is, each of the electronic circuits E1 to E3 includes a constant current diode (CRD). The CRD is an element capable of flowing a constant current even when the applied voltage changes. In the LED driver 301 of this embodiment, the output terminals O1 to O3 are connected to the anode side of the CRD, and the cathode side of the CRD is connected to the ground (grounded). Therefore, by providing the CRD, a constant current flows from the output terminals O1 to O3 → CRD → ground. However, the MOS transistor m is provided between the CRD and the ground. Specifically, the drain side of the MOS transistor m is connected to the cathode side of the constant current diode (CRD), and the source side of the MOS transistor m is connected to the ground. Therefore, when the MOS transistor m is turned on (when the source-drain conducts), a constant current flows from the output terminals O1 to O3, CRD, and ground. In order to turn on the MOS transistor m, a voltage needs to be applied to the gate of the MOS transistor m, and the node IN is connected to this gate. That is, when a voltage is applied to this node IN (when a signal is input), a constant current flows from the output terminals O1 to O3 → CRD → ground. In this case, a current naturally flows through the wirings H11 to H13 (red LED 71, green LED 72, and blue LED 73).

  The LED driver 301 of this embodiment includes various electronic circuits in addition to the electronic circuits E1 to E3 described above, and is used to receive (analyze) a lighting pattern designation command transmitted from the sub control board 220. An electronic circuit (also referred to as a “command analysis circuit” in this specification) is also mounted.

  This command analysis circuit applies a voltage to the node IN of the electronic circuit E1 when the lamp 5 is turned on in red (when a lighting pattern designation command indicating that the lamp 5 is turned on in red is received). A constant current flows from the output terminal O1 to the CRD to the ground. In this case, of course, current also flows through the wiring H11 and the red LED 71.

  When the lamp 5 is lit green (when a lighting pattern designation command indicating that the lamp 5 is lit green is received), a constant current is applied by applying a voltage to the node IN of the electronic circuit E2. Output terminal O2 → CRD → ground. In this case, a current naturally flows through the wiring H12 and the green LED 72.

  When the lamp 5 is turned on in blue (when a lighting pattern designation command indicating that the lamp 5 is turned on in blue is received), a constant current is applied by applying a voltage to the node IN of the electronic circuit E3. Output terminal O3 → CRD → ground. In this case, a current naturally flows through the wiring H13 and the blue LED 73.

  The electronic circuits E1 to E3 are provided with resistors R21 to R23 for defining (adjusting) the voltage applied to each node, in addition to the elements described above.

  As described above, the LED driver 301 of the present embodiment can supply a constant current to the output terminals O1 to O3 by including the electronic circuits E1 to E3. The value of this constant current is defined by the resistance value of the resistor Rx connected to the terminal EXT of the LED driver 301. In the present embodiment, a resistor Rx having a resistance value at which the current flowing through the output terminals O1 to O3 becomes 30 mA is connected.

  Here, as described above, when the current flowing through the output terminals O1 to O3 is 30 mA, the current of 30 mA naturally flows through the red LED 71, the green LED 72, and the blue LED 73 (wirings H11 to H13). In this case, the red LED 71 having a drive current of 30 mA has an appropriate current value, and thus emits light without any problem. However, the green LED 72 having a drive current of 20 mA and the blue LED 73 having a drive current of 10 mA have the same drive current. Current may flow, and may be damaged.

  Therefore, in the pachinko machine 1 of the present embodiment, the following contrivance is made. That is, as described above, the constant current type LED driver 301 can supply a constant current to the output terminals O1 to O3. However, there is a condition, and the voltage Vac (the potential difference Vac between the node Na on the anode side and the node Nc on the cathode side of the CRD) applied to the CRD provided in the electronic circuits E1 to E3 is within a predetermined range. There is a need. FIG. 11 shows the voltage-current characteristics of the CRD. As shown in FIG. 11, when the applied voltage Vac is equal to or higher than Vth (threshold, for example, 2.5 V), a constant current (here, 30 mA) flows, but the CRD in this embodiment is lower than Vth. If there is, there is a characteristic that a current depending on the applied voltage flows (to the output terminal). Therefore, in order to take advantage of the characteristics of the constant current type LED driver 301 (the characteristic that a constant current flows to the output terminal) in the related art, each element is set so that a voltage of Vth or more is applied to the CRD. Was connected.

  In the present embodiment, contrary to the above, the electronic circuit E2 and the electronic circuit E3 are configured to apply only a voltage lower than Vth to the CRD. That is, as described above, by paying attention to the fact that the CRD has a characteristic that a current depending on the voltage flows when the applied voltage is lower than Vth, only the voltage lower than Vth is applied to the CRD ( The potential difference Vac between the node Na on the anode side of the CRD and the node Nc on the cathode side is made smaller than Vth.) The resistors R10 and R11 are provided. This intentionally causes a current depending on the voltage applied to the CRD to flow through the output terminals O2 and O3.

  Specifically, regarding the electronic circuit E2, by providing the resistor R10 between the CRD and the green LED 72 (wiring H12), only the voltage of V2 (for example, 1.0 V) smaller than Vth is applied to the CRD ( The potential difference Vac between the node Na on the anode side of the CRD and the node Nc on the cathode side is set to V2 smaller than Vth), and 20 mA which is a current depending on the voltage V2 applied to the CRD flows through the output terminal O2. did. As a result, even when the constant-current type LED driver 301 that supplies a constant current of 30 mA is used, a current of 20 mA can be supplied to the output terminal O2 (green LED 72), and the green LED 72 is defective. It is possible to emit light without any.

  Further, regarding the electronic circuit E3, by providing the resistor R11 between the CRD and the blue LED 73 (wiring H13), only the voltage of V3 (for example, 0.5 V) smaller than Vth is applied to the CRD (CRD The potential difference Vac between the node Na on the anode side and the node Nc on the cathode side is set to V3 smaller than Vth), and 10 mA, which is a current depending on the voltage V3 applied to the CRD, flows through the output terminal O3. . As a result, even when the constant-current type LED driver 301 that supplies a constant current of 30 mA is used, a current of 10 mA can be supplied to the output terminal O3 (blue LED 73), and the blue LED 73 may be defective. It is possible to emit light without any.

  As described above, in the pachinko machine 1 of the present embodiment, "when using the constant current type LED driver 301, a voltage equal to or higher than Vth is applied to the CRD and a constant current flows through the output terminals O1 to O3." A configuration that overturns the obvious was adopted. That is, in the electronic circuits E2 and E3, only a voltage lower than Vth is applied to the CRD so that a current depending on the voltage applied to the CRD flows intentionally through the output terminals O2 and O3. did. As a result, even when the constant-current LED driver 301 is used (while the luminance of the red LED 71 is stabilized by using the constant-current LED driver 301), the red LEDs 71 having different driving currents from each other are used. The green LED 72 and the blue LED 73 can emit light without any trouble.

  Further, the LED driver 301 of this embodiment has a terminal EXT to which a resistor for limiting the maximum value of the current that can flow to the output terminals O1 to O3 is connected. , A resistor Rx for limiting the maximum value to 30 mA, which is the drive current of the red LED 71, is connected. In other words, the drive current of the red LED 71 can flow to the output terminal O1 (red LED 71) only by connecting the resistor Rx to the terminal EXT. (It is not necessary to provide resistors corresponding to the devices R10 and R11), and the productivity can be improved.

  The output terminal O1 can be regarded as a "first terminal", and the output terminals O2 and O3 can be regarded as a "second terminal". Further, the wiring H11 can be regarded as a “first wiring”, and the wirings H12 and H13 can be regarded as a “second wiring”. The red LED 71 can be regarded as a “first LED”, and the green LED 72 and the blue LED 73 can be regarded as a “second LED”. Further, the resistors R10 and R11 can be regarded as “current limiting resistors”. Further, the electronic circuit E1 can be regarded as a “first electronic circuit”, and the electronic circuits E2 and E3 can be regarded as a “second electronic circuit”.

D. Modifications:
Next, a modified example will be described.
D-1. Modification 1:
In the first modification, the LED driver 501 is employed instead of the LED driver 301 described above. The LED driver 501 is also a constant current type like the LED driver 301, and includes electronic circuits E11 to E13 instead of the electronic circuits E1 to E3 described above.

  FIG. 12 is an explanatory diagram showing the electronic circuits E11 to E13. As shown in FIG. 12, the constant current type LED driver 501 includes electronic circuits E11 to E13 having the same circuit configuration. These electronic circuits E11 to E13 have a function of flowing a constant current to the output terminals O1 to O3.

  That is, each of the electronic circuits E11 to E13 includes the bipolar transistor b between the output terminals O1 to O3 and the ground. Specifically, the collector side of the bipolar transistor b is connected to the output terminals O1 to O3, and the emitter side of the bipolar transistor b is connected to the ground. Therefore, when the bipolar transistor b is turned on (when the collector-emitter conducts), a constant current flows from the output terminals O1 to O3 to the ground. In order to turn on the bipolar transistor b, it is necessary to apply a voltage to the base of the bipolar transistor b. The base IN is connected to the node IN. That is, when a voltage is applied to this node IN (when a signal is input), a constant current flows from the output terminals O1 to O3 to the ground. In this case, a current naturally flows through the wirings H11 to H13 (red LED 71, green LED 72, and blue LED 73).

  The LED driver 501 of the first modification includes various electronic circuits in addition to the above-described electronic circuits E11 to E13, and is used to receive (analyze) a lighting pattern designation command transmitted from the sub-control board 220. An electronic circuit (also referred to as a “command analysis circuit” in this specification) is also mounted.

  This command analysis circuit applies a voltage to the node IN of the electronic circuit E11 when the lamp 5 is turned on in red (when a lighting pattern designation command indicating that the lamp 5 is turned on in red is received). A constant current flows from the output terminal O1 to the ground. In this case, of course, current also flows through the wiring H11 and the red LED 71.

  When the lamp 5 is lit green (when a lighting pattern designation command indicating that the lamp 5 is lit green is received), a constant current is applied by applying a voltage to the node IN of the electronic circuit E12. Flow from output terminal O2 to ground. In this case, a current naturally flows through the wiring H12 and the green LED 72.

  When the lamp 5 is turned on in blue (when a lighting pattern designation command indicating that the lamp 5 is turned on in blue is received), a constant current is applied by applying a voltage to the node IN of the electronic circuit E13. Flow from output terminal O3 to ground. In this case, a current naturally flows through the wiring H13 and the blue LED 73.

  The electronic circuits E11 to E13 are provided with resistors R31 to R33 for defining (adjusting) the voltage applied to each node, in addition to the elements described above.

  As described above, the LED driver 501 of the first modification can supply a constant current to the output terminals O1 to O3 by including the electronic circuits E11 to E13. The value of this constant current is defined by the resistance value of the resistor Rx connected to the terminal EXT of the LED driver 501. Also in the first modification, a resistor Rx having a resistance value at which the current flowing through the output terminals O1 to O3 becomes 30 mA is connected.

  Here, as described above, when the current flowing through the output terminals O1 to O3 is 30 mA, the current of 30 mA naturally flows through the red LED 71, the green LED 72, and the blue LED 73 (wirings H11 to H13). In this case, the red LED 71 having a drive current of 30 mA has an appropriate current value, and thus emits light without any problem. However, the green LED 72 having a drive current of 20 mA and the blue LED 73 having a drive current of 10 mA have the same drive current. Current may flow, and may be damaged.

  Therefore, in the first modification, the following measures are taken. That is, as described above, the constant current type LED driver 501 can supply a constant current to the output terminals O1 to O3. However, there is a condition, and the voltage Vce (between the collector node Nc and the emitter node Ne of the bipolar transistor b) applied to (between the collector and the emitter of) the bipolar transistor b provided in the electronic circuits E11 to E13. The potential difference Vce between them must be within a predetermined range. FIG. 13 shows a voltage-current characteristic of the bipolar transistor b. As shown in FIG. 13, in the bipolar transistor b of the first modification, when the applied voltage Vce is equal to or higher than Vth2 (threshold, for example, 2.5 V), a constant current (here, 30 mA) flows from the collector side to the emitter side. Although it flows to the side, if it is lower than Vth2, a current depending on the applied voltage has a characteristic of flowing from the collector side (to the output terminal) to the emitter side. For this reason, naturally, in order to take advantage of the characteristics of the constant current type LED driver 501 (the characteristic that a constant current flows to the output terminal), the bipolar transistor b (between the collector and the emitter thereof) must have Vth2 or more. Each element was connected so that a voltage could be applied.

  In the first modification, the above-described matter is reversed, and in the electronic circuit E12 and the electronic circuit E13, only a voltage lower than Vth2 is applied to (between the collector and the emitter of) the bipolar transistor b. That is, paying attention to the fact that the bipolar transistor b has the above-mentioned characteristic that if the applied voltage is lower than Vth2, a current depending on the voltage flows from the collector side to the emitter side. A resistor R20 and a resistor R21 are provided so that only a voltage lower than Vth2 is applied between the emitters (between the collector node Nc and the emitter node Ne of the bipolar transistor b is lower than Vth2). I decided that. Thereby, a current depending on the voltage applied to (between the collector and the emitter of) the bipolar transistor b flows intentionally into the output terminals O2 and O3.

  More specifically, in the electronic circuit E12, by providing a resistor R20 between the bipolar transistor b and the green LED 72 (wiring H12), a voltage V2 smaller than Vth2 (for example, 1. 0V) (the potential difference Vce between the node Nc on the collector side and the node Ne on the emitter side of the bipolar transistor b is set to V2 smaller than Vth2). This allows a current of 20 mA, which depends on the voltage V2 applied to (between the collector and the emitter) of the bipolar transistor b, to flow to the output terminal O2. As a result, even when the constant current type LED driver 501 that supplies a constant current of 30 mA is used, a current of 20 mA can be supplied to the output terminal O2 (green LED 72), which causes the green LED 72 to malfunction. It is possible to emit light without any.

  In addition, regarding the electronic circuit E13, by providing the resistor R21 between the bipolar transistor b and the blue LED 73 (wiring H13), V3 (for example, 0.5 V) smaller than Vth2 (between the collector and the emitter of the bipolar transistor b) is provided. ) (The potential difference Vce between the node Nc on the collector side and the node Ne on the emitter side of the bipolar transistor b is set to V3 smaller than Vth2). This allows a current of 10 mA, which depends on the voltage V3 applied to (between the collector and the emitter of) the bipolar transistor b, to flow to the output terminal O3. As a result, even when the constant current type LED driver 501 that supplies a constant current of 30 mA is used, a current of 10 mA can be supplied to the output terminal O3 (blue LED 73). It is possible to emit light without any.

  As described above, in the first modification, “when using the constant current type LED driver 501, a voltage of Vth2 or more is applied to (between the collector and the emitter of) the bipolar transistor b and a constant voltage is applied to the output terminals O1 to O3. A configuration that overturns the natural flow of current is adopted. That is, in the electronic circuits E12 and E13, only the voltage lower than Vth2 is applied to (between the collector and the emitter of) the bipolar transistor b, so that the bipolar transistors b (of the output terminals O2 and O3 are intentionally applied to the output terminals O2 and O3). A current depending on the voltage applied between the collector and the emitter) was caused to flow. As a result, even when the constant current type LED driver 501 is used (while the luminance of the red LED 71 is stabilized by using the constant current type LED driver 501), the red LEDs 71 having different driving currents from each other are used. The green LED 72 and the blue LED 73 can emit light without any trouble.

  Further, the LED driver 501 of the first modification has a terminal EXT to which a resistor for limiting the maximum value of the current that can flow to the output terminals O1 to O3 is connected. The terminal EXT is connected to a resistor Rx that limits the maximum value to 30 mA, which is the drive current of the red LED 71. In other words, the drive current of the red LED 71 can flow to the output terminal O1 (red LED 71) only by connecting the resistor Rx to the terminal EXT. It is not necessary to provide resistors corresponding to the devices R20 and R21), and the productivity can be improved.

  In addition, also in the modified example 2, the output terminal O1 can be regarded as a “first terminal”, the output terminals O2 and O3 can be regarded as a “second terminal”, and the terminal EXT is referred to as a “third terminal”. Can be caught. Further, the wiring H11 can be regarded as a “first wiring”, and the wirings H12 and H13 can be regarded as a “second wiring”. The red LED 71 can be regarded as a “first LED”, and the green LED 72 and the blue LED 73 can be regarded as a “second LED”. Further, the resistors R10 and R11 can be regarded as “current limiting resistors”. Further, the electronic circuit E11 can be regarded as a “first electronic circuit”, and the electronic circuits E12 and E13 can be regarded as a “second electronic circuit”.

D-2. Modification 2:
In the above-described embodiment and the first modification, the example in which the red LED 71, the green LED 72, and the blue LED 73 having different driving currents are connected to the output terminals O1 to O3 of the constant current type LED driver 301 and the LED driver 501, respectively. The present invention is not limited to this, and different numbers of LEDs may be connected to the output terminals O1 to O3.

  For example, as shown in FIG. 14, three blue LEDs 73 are connected in parallel (drive current = 10 mA × 3) to the output terminal O 1 (the wiring H 11 through which a current of 30 mA flows) of the constant current type LED driver 301, and the output is performed. Two blue LEDs 73 are connected in parallel to the terminal O2 (the wiring 12 through which a current of 20 mA flows) (drive current = 10 mA × 2), and one blue LED 73 is connected to the output terminal O3 (the wiring H13 through which a current of 10 mA flows). It may be connected (drive current = 10 mA × 1).

  Here, the constant current type LED driver 301 normally (if it is conventional) supplies a constant current to the output terminals O1 to O3, so that a different number of LEDs (here, three blue LEDs 73, If two blue LEDs 73 and one blue LED 73) are connected, a problem occurs. For example, when a current of 30 mA corresponding to the drive current of the three blue LEDs 73 is caused to flow (drive) the three blue LEDs 73 through the output terminal O1, a current of 30 mA also flows through the output terminals O2 and O3. As a result, the LEDs (two blue LEDs 73 and one blue LED 73) connected to these terminals may be damaged. Conversely, when a current of 10 mA corresponding to a drive current of one blue LED 73 is supplied to the output terminal O3 to emit (drive) one blue LED 73, only a current of 10 mA flows to the output terminals O1 and O2. Therefore, the LEDs (three blue LEDs 73 and two blue LEDs 73) connected to these terminals do not emit light, or the brightness of these LEDs becomes insufficient.

  In this regard, if the resistor R10 similar to that of the above-described embodiment is provided on the wiring H12, the LED driver 301 can flow a current of 20 mA to the output terminal O2 (wiring H12). A current of 10 mA flows through each of the two blue LEDs 73 connected in parallel. Further, if the same resistor R11 as in the above-described embodiment is provided on the wiring H13, the LED driver 301 can flow a current of 10 mA to the output terminal O3 (wiring H13). As a result, even when the constant current type LED driver 301 is used, it is possible to cause LEDs having different numbers to emit light without any trouble.

  In addition, the LED driver 301 has a terminal EXT to which a resistor for limiting the maximum value of the current that can flow to the output terminals O1 to O3 is connected. The terminal EXT is connected to a resistor Rx that limits the maximum value to 30 mA, which is a drive current (drive current = 10 mA × 3) for the three blue LEDs 73. That is, only by connecting the resistor Rx to the terminal EXT, the drive current of the three blue LEDs 73 can flow to the output terminal O1, so that the three blue LEDs 73 (the blue LEDs 73 connected to the output terminal O1) are not included. There is no need to add electronic components to the device (no need to provide resistors corresponding to the resistors R10 and R11), and it is possible to improve productivity.

  The output terminal O1 can be regarded as a "first terminal", the output terminals O2 and O3 can be regarded as a "second terminal", and the terminal EXT can be regarded as a "third terminal". . Further, the wiring H11 can be regarded as a “first wiring”, and the wirings H12 and H13 can be regarded as a “second wiring”. The red LED 71 can be regarded as a “first LED”, and the green LED 72 and the blue LED 73 can be regarded as a “second LED”. Further, among the three blue LEDs 73 connected to the output terminal O1, the two blue LEDs 73 connected to the output terminal O2, and the one blue LED 73 connected to the output terminal O3, the one with the larger number is the “first”. The “number of LEDs” can be regarded as “the number of LEDs”, and the smaller number can be regarded as “the second number of LEDs”.

D-3. Modification 3:
In the above-described embodiment and the first modification, by providing the resistor R10, 20 mA flows to the output terminal O2 (wiring H12), and by providing the resistor R11, 10 mA flows to the output terminal O3 (wiring H13). I made it. However, the invention is not limited thereto, and the resistors R10 and R11 may not be provided. That is, in this case, a current of 30 mA flows through the output terminal O2 (wiring H12) and the output terminal O3 (wiring H13), similarly to the output terminal O1 (wiring H11).

  Therefore, as shown in FIG. 15, the wiring H12 branches into the wiring H21 and the wiring H22, and the green LED 72 is connected to the wiring H21, and the resistor R30 is connected to the wiring H22. At this time, the resistance value of the resistor R30 is set so that a current of 20 mA flows through the wiring H21 (so that a current of 10 mA flows through the wiring 22). The wiring H13 branches into a wiring H23 and a wiring H24, and the blue LED 73 is connected to the wiring H23, and a resistor R31 is connected to the wiring H24. At this time, the resistance value of the resistor R31 is set so that a current of 10 mA flows through the wiring H23 (so that a current of 20 mA flows through the wiring 24). As a result, even when the constant-current LED driver 301 is used (while the luminance of the red LED 71 is stabilized by using the constant-current LED driver 301), the red LEDs 71 having different driving currents from each other are used. The green LED 72 and the blue LED 73 can emit light without any trouble.

  In addition, the LED driver 301 has a terminal EXT to which a resistor for limiting the maximum value of the current that can flow to the output terminals O1 to O3 is connected. The terminal EXT is connected to a resistor Rx that limits the maximum value to 30 mA, which is the drive current of the red LED 71. In other words, the drive current of the red LED 71 can flow to the output terminal O1 (red LED 71) only by connecting the resistor Rx to the terminal EXT. It is not necessary to provide resistors corresponding to the devices R30 and R31), and the productivity can be improved.

  The output terminal O1 can be regarded as a "first terminal", the output terminals O2 and O3 can be regarded as a "second terminal", and the terminal EXT can be regarded as a "third terminal". . Further, the wiring H11 can be regarded as a “first wiring”, and the wirings H12 and H13 can be regarded as a “second wiring”. The red LED 71 can be regarded as a “first LED”, and the green LED 72 and the blue LED 73 can be regarded as a “second LED”.

However, the present invention is not limited thereto, and is not limited to the language described in each claim unless departing from the scope described in each claim. Those skilled in the art can easily replace them, and can appropriately add improvements based on the knowledge usually possessed by those skilled in the art.

An example in which is applied has been described. The present invention is not limited to this, and the present invention can also be applied to a gaming machine of a type that provides a gaming benefit in a form different from “payout of gaming balls”.

<Gaming machines A1 to A6 that can be extracted from the above-described embodiment>
The pachinko machine of the embodiment described above can be considered as the following gaming machines A1 to A6.

<Game machine A1>
A gaming machine that performs a game using a game medium,
A constant current type LED driver having a first terminal and a second terminal, and capable of flowing a current of a predetermined value to the first terminal and the second terminal;
A first LED connected to the first terminal via a first wiring,
A second LED connected to the second terminal via a second wiring and having a lower drive current than the first LED;
With
The second wiring of the first wiring and the second wiring is provided with a current limiting resistor which is a resistor for reducing a current flowing through the second wiring to a value smaller than the predetermined value. A gaming machine characterized by:

  In such a gaming machine, the constant current type LED driver supplies a predetermined value of current (the same current) to the first terminal and the second terminal, so that LEDs having different driving currents (first LED, If the second LED is connected to the first terminal and the second terminal, a problem occurs. For example, in order to cause the first LED to emit light (to drive it), a current corresponding to a drive current of the first LED (also referred to herein as a “large current”) is supplied to the first terminal. Therefore, a "large current" flows, and the second LED may be damaged. Conversely, when a current corresponding to a driving current of the second LED (herein, also referred to as “small current”) is caused to flow to the second terminal in order to cause the second LED to emit light (to drive it), the first terminal A “small current” also flows through the terminal, and the first LED does not emit light or the brightness of the first LED becomes insufficient.

  Therefore, in the present gaming machine, a “current limiting resistor” that makes the magnitude of the current flowing through the second wiring (second LED) smaller than a predetermined value is provided on the second wiring. In this case, even if a “large current” is caused to flow (drive) the first LED to the first terminal, the “large current (second wiring)” is applied to the second terminal (second wiring). Only a current smaller than "predetermined value)" flows, and damage to the second LED can be prevented. As a result, even when a constant current type LED driver is used, LEDs having different driving currents can emit light without any trouble.

<Game machine A2>
A gaming machine that performs a game using a game medium,
A constant current type LED driver having a first terminal and a second terminal, and capable of flowing a current of a predetermined value to the first terminal and the second terminal;
A first wiring having one end connected to the first terminal;
A second wiring having one end connected to the second terminal;
With
A first number of LEDs are connected to the other end of the first wiring,
A second number of LEDs smaller than the first number is connected to the other end of the second wiring,
The second wiring of the first wiring and the second wiring is provided with a current limiting resistor which is a resistor for reducing a current flowing through the second wiring to a value smaller than the predetermined value. A gaming machine characterized by:

  In such a gaming machine, the constant current type LED driver supplies a predetermined value of current (the same current) to the first terminal and the second terminal, so that different numbers of LEDs (first number of LEDs) are used. , A second number of LEDs) to the first terminal and the second terminal, a problem occurs. For example, when a current corresponding to a driving current of the first number of LEDs (here, also referred to as a “large current”) is caused to flow to the first terminal in order to emit (drive) the first number of LEDs, The “large current” also flows through the second terminal, and there is a possibility that a second number of LEDs less than the first number may be damaged. Conversely, in order to cause the second number of LEDs to emit light (to drive them), a current (also referred to as “small current”) corresponding to the drive current of the second number of LEDs flows to the second terminal. The "small current" also flows through the first terminal, and the first number of LEDs greater than the second number does not emit light, or the first number of LEDs has insufficient luminance.

  Therefore, in the present gaming machine, a “current limiting resistor” that makes the magnitude of the current flowing through the second wiring (second LED) smaller than a predetermined value is provided on the second wiring. In this case, even if a “large current” is caused to flow (drive) the first number of LEDs to the first terminal, the “large current” is applied to the second terminal (second wiring). Only a current smaller than the “current (predetermined value)” flows, and damage to the second number of LEDs can be prevented. As a result, even when a constant current type LED driver is used, it is possible to cause LEDs having different numbers to emit light without any problem.

<Game machine A3>
In the gaming machine A1 or the gaming machine A2,
The LED driver comprises:
By applying a potential difference equal to or greater than a predetermined threshold value between predetermined nodes of the first electronic circuit of the LED driver, the current of the predetermined value can flow through the first terminal,
When a potential difference equal to or greater than the predetermined threshold is given between predetermined nodes of a second electronic circuit of the LED driver, the current of the predetermined value can flow through the second terminal,
The gaming machine, wherein the current limiting resistor is a resistor that causes a potential difference less than the predetermined threshold value to be applied between the predetermined nodes of the second electronic circuit.

  A general constant current type LED driver can supply a current of a predetermined value (a so-called pinch-off current) to a terminal unless a potential difference equal to or more than a predetermined threshold is applied between predetermined nodes of a built-in electronic circuit. If the potential difference is less than a predetermined threshold value, a current depending on the potential difference (a current less than a predetermined value) flows. The same applies to the constant current type LED driver of the gaming machine. If a potential lower than a predetermined threshold is applied between predetermined nodes of the built-in electronic circuit, a current depending on the potential difference (less than a predetermined value) Flows through the first terminal and the second terminal. This gaming machine pays attention to this, and, for the second electronic circuit, by providing a “current limiting resistor” between predetermined nodes so as to prevent application of a potential less than a predetermined threshold, A current (current less than a predetermined value) depending on the potential difference flows intentionally through the second terminal. In this case, even when a “large current” is caused to flow (to drive) the first LED (or the first number of LEDs) to the first terminal, the second terminal (or the first number of LEDs) is turned on. Only a current smaller than the “large current (predetermined value)” flows through the second wiring, and damage to the second LED (or a second number of LEDs smaller than the first number) can be prevented. As a result, even when a constant current type LED driver is used, it is possible to cause LEDs having different driving currents (or numbers) to emit light without any trouble.

  In such a gaming machine, the constant current type LED driver supplies a predetermined value of current (the same current) to the first terminal and the second terminal, so that LEDs having different driving currents (first LED, If the second LED is connected to the first terminal and the second terminal, a problem occurs. For example, in order to cause the first LED to emit light (to drive it), a current corresponding to a driving current of the first LED (also referred to herein as a “large current”) is supplied to the first terminal. Therefore, a "large current" flows, and the second LED may be damaged. Conversely, when a current (also referred to as “small current” here) corresponding to the drive current of the second LED is caused to flow to the second terminal in order to emit (drive) the second LED, the first LED A “small current” also flows through the terminal, and the first LED does not emit light or the brightness of the first LED becomes insufficient.

  Therefore, in this gaming machine, the second wiring (second LED) is branched, a second LED is connected to one of the branches, and a resistor is provided to the other of the branches. did. In such a case, when a "large current" is caused to flow (drive) the first LED to the first terminal, a "large current" also flows to the second terminal (second wiring). The current will be shunted beyond. For this reason, only a current smaller than the “large current (predetermined value)” flows through the second LED, and damage to the second LED can be prevented. As a result, even when a constant current type LED driver is used, LEDs having different driving currents can emit light without any trouble.
