About.
[0002]
[Prior art]
In recent gaming machines such as pachinko machines and slot machines, for example, light-emitting diodes are often used as display lamps (light-emitting elements) for performing symbol display or decoration display. There is a tendency to use a combination of light emitting diodes of three colors of RGB (red, green, and blue). As a simple lighting control method for controlling multi-color lighting of such RGB light emitting diodes, for example, a dynamic lighting control method is generally used. In this dynamic lighting control method, a driving voltage common to each RGB light emitting diode is used. Is applied.
[0003]
[Problems to be solved by the invention]
By the way, the R light emitting diode that emits red light, the G light emitting diode that emits green light, and the B light emitting diode that emits blue light have greatly different forward voltage drops due to the difference in characteristics. For example, when a common driving voltage is applied to each light emitting diode, the forward voltage drop of the R light emitting diode is 1.2 V, the forward voltage drop of the G light emitting diode is 1.7 V, and the B light emitting diode. The forward voltage drop is 3.8V.
[0004]
Therefore, when such RGB light emitting diodes are used and a common drive voltage is applied to each light emitting diode, the forward voltage drop of each light emitting diode is greatly different as described above. There is a problem that the variation becomes large, and the display unit in the gaming machine using each of the RGB light emitting diodes exhibits a light emission color with a nonuniform light emission luminance balance.
[0005]
Therefore, a circuit configuration is also conceivable in which each light emitting diode has the same current by connecting a light emitting luminance adjusting resistor having a different resistance value to each light emitting diode so that each RGB light emitting diode has the same light emitting luminance. However, when the number of light emitting diodes increases, the number of resistors also increases, and the circuit configuration becomes complicated.
[0006]
The present invention has been made in order to solve the above-described problems, and has a simple circuit configuration and a light emission control circuit in which the light emitting elements constituting the display unit can have the same light emission luminance regardless of the light emission color. An object is to provide a gaming machine having a section.

A predetermined driving voltage for driving the red light emitting element and the green light emitting element is generated on the basis of the driving voltage of the blue light emitting element so that the light emission luminances of the elements are the same or substantially the same. When the light emission control circuit drives the light emitting element based on an instruction from the main game control unit, the drive voltage application condition for the light emitting element is read from the storage unit, and according to the read application condition, The power supply voltage from the power supply circuit unit is applied to the blue light emitting element, or the divided voltage from the voltage dividing means is applied to the red light emitting element and the green light emitting element.The present invention provides a gaming machine characterized by this.
[0008]
According to such an invention, the plurality of light emitting elements constituting the display unit can be controlled by the light emission control circuit unit, for example, by setting the predetermined value so that the light emission luminance of each light emitting element is the same. The same emission luminance can be obtained. Accordingly, for example, the R light emitting diode, the G light emitting diode, and the B light emitting diode can each have the same light emission luminance, and the display unit can exhibit light emission colors with a good light emission luminance balance. .

As a result, it is possible to apply a driving voltage that gives the same light emission luminance to each light emitting element.
[0016]
  According to this invention, when the light emission control circuit unit receives a display command from the main game control unit, a switching signal is generated from the switching signal generating means of the light emission control circuit unit. As a result, the divided voltage by the voltage dividing means is switched and light emission is performed.elementA predetermined drive voltage is applied to.

[0064]
Next, with reference to FIGS. 1-3, FIG. 5, and FIG. 6, the operation | movement of the lighting control of the light emitting element in the game machine which concerns on this embodiment is demonstrated. In order for the R, G, and B light-emitting diodes LR, LG, and LB to have the same light emission luminance, it is necessary to pass the same current I to each of the light-emitting diodes LR, LG, and LB. Since each light emitting diode LR, LG, LB has a different forward voltage drop, the driving voltage (applied voltage) to each light emitting diode LR, LG, LB is set to a different value so that the current I is the same. ing. That is, the voltages applied to the light emitting diodes LR, LG, and LB are set to predetermined values so that the light emitting luminances of the light emitting diodes LR, LG, and LB are the same.
[0065]
Here, as described above, since the forward voltage drop of the B light emitting diode LB is larger than the forward voltage drop of the R and G light emitting diodes LR and LG, the drive voltage to the B light emitting diode LB is set as follows. Each drive voltage is set as a reference. Hereinafter, each drive voltage to each light emitting diode LR, LG, LB will be described as Er, Eg, Eb. The drive voltages Er, Eg, and Eb may be 8V, 10V, and 12V, for example. However, the drive voltages Er, Eg, and Eb are not limited to this.
[0066]
Here, for easy understanding, a case where the blue light emitting diode LB11, the green light emitting diode LG11, and the red light emitting diode LR11 are lit in this order will be described. When the CPU 19 of the symbol display sub-board 15 inputs, for example, a 1-bit strobe signal from the main game control unit 13 and a blue display command signal including, for example, an 8-bit parallel signal for displaying blue on the display, the ROM 20 The B transistor array 16 is operated in accordance with the stored application condition of the blue driving voltage, and the blue light emitting diode LB11 connected to the line c is turned on.
[0067]
The drive voltage Eb for the blue light emitting diode LB11 is directly applied from the power supply circuit unit 12. At this time, the B transistor array 16 selects the line c by turning on the common side signal B1, and outputs the power supply voltage from the power supply circuit unit 12 to the line 1c as the drive voltage Eb. Further, the transistor array 18 selects the line d by turning on the segment side signal D1, and allows the current from the blue light emitting diode LB11 to flow. At this time, the counter circuit 5 in the switching signal generation circuit 102 is in a reset state.
[0068]
Next, when the CPU 19 inputs, for example, a 1-bit strobe signal from the main game control unit 13 and a green display command signal including, for example, an 8-bit parallel signal for displaying green on the display, the CPU 19 stores the green display command signal. The G / R transistor array 17 is operated in accordance with the application condition of the green driving voltage, and the green light emitting diode LG11 connected to the line b is turned on. The driving voltage Eg for the light emitting diode LG11 is supplied from the voltage dividing circuit 101.
[0069]
Specifically, in the switching signal generation circuit 102, the power supply switching circuit 1 generates a clock signal in accordance with the green power supply switching command signal from the CPU 19 and applies this clock signal to the clock terminal CK of the counter circuit 5. As a result, a high level drive voltage switching signal SG is outputted from the output terminal Q0 from the counter circuit 5, and the transistor T1 of the voltage dividing circuit 101 is turned on.
[0070]
Therefore, a voltage adjusted based on the resistors R1 and R2 is output from the regulator 4 to the line L2, and this voltage is given as a drive voltage Eg to the green light emitting diode LG11 via the G / R transistor array 17. As a result, the green light emitting diode LG11 is turned on.
[0071]
That is, the drive voltage Eg for the green light emitting diode LG11 is supplied from the voltage dividing circuit 101. At this time, the G / R transistor array 17 selects the line b by turning on the common side signal G1, and outputs the divided voltage from the voltage dividing circuit 101 to the line b as the drive voltage Eg. Further, the transistor array 18 selects the line d by turning on the segment side signal D1, and allows the current from the green light emitting diode LG11 to flow. As a result, the green light emitting diode LG11 is turned on.
[0072]
Next, when the CPU 19 inputs, for example, a 1-bit strobe signal from the main game control unit 13 and a red display command signal including, for example, an 8-bit parallel signal for displaying red on the display, the CPU 19 stores the red display command signal. The G / R transistor array 17 is operated according to the application condition of the red driving voltage, and the red light emitting diode LR11 connected to the line a is turned on. The drive voltage Er for the light emitting diode LR11 is supplied from the voltage dividing circuit 101.
[0073]
Specifically, in the switching signal generation circuit 102, the power switching circuit 1 generates a clock signal in accordance with a red power switching command signal from the CPU 19 and applies this clock signal to the clock terminal CK of the counter circuit 5. As a result, the signal at the output terminal Q0 of the counter circuit 5 changes from the high level to the low level, and instead, a high level drive voltage switching signal SR is output from the output terminal Q1, and the transistor T2 of the voltage dividing circuit 101 is turned on. Is done.
[0074]
Therefore, a voltage adjusted based on the resistors R1 and R3 is output from the regulator 4 to the line L2, and this voltage is applied as a drive voltage Er to the red light emitting diode LR11 via the G / R transistor array 17. As a result, the red light emitting diode LR11 is turned on.
[0075]
That is, the drive voltage Er for the red light emitting diode LR11 is supplied from the voltage dividing circuit 101. At this time, the G / R transistor array 17 selects the line a by turning on the common side signal R1, and outputs the divided voltage from the voltage dividing circuit 101 to the line a as the drive voltage Er. In addition, the transistor array 18 selects the line d by turning on the segment side signal D1, and allows the current from the red light emitting diode LR11 to flow. As a result, the red light emitting diode LR11 is turned on.
[0076]
Next, when the CPU 19 inputs a blue display command signal including, for example, a 1-bit strobe signal from the main game control unit 13 and, for example, an 8-bit parallel signal for displaying a blue color on the display, in response thereto The power supply switching circuit 1 of the switching signal generation circuit 102 generates a clock signal in accordance with the blue power supply switching command signal from the CPU 19 and applies this clock signal to the clock terminal CK of the counter circuit 5. As a result, the signal at the output terminal Q1 of the counter circuit 5 changes from the high level to the low level. Instead, a high level signal is output from the output terminal Q2, and the clear terminal CLR of the counter circuit 5 is output via the OR gate 3. The counter circuit 5 is cleared.
[0077]
Accordingly, at this time, since the signals at the output terminals Q0 and Q1 of the counter circuit 5 are at a low level, the transistors T1 and T2 of the voltage dividing circuit 101 are in an off state, and no voltage is output from the regulator 4. As a result, the light emitting diodes LG11 and LR11 are not turned on, and the light emitting diode LB11 is turned on.
[0078]
In this way, the light-emitting diodes are switched for each color, and a constant current flows through the light-emitting diodes of the respective colors.
[0079]
In the above description, the lighting control of the red light emitting diode LR11, the green light emitting diode LG11, and the blue light emitting diode LB11 is described, but the lighting control of the other light emitting diodes LR12, LG12, LB12, and the like is the same. .
[0080]
  FIG. 4 illustrates the present invention.Reference exampleFIG. 2 is a circuit block configuration diagram showing a circuit block of a symbol display circuit section in FIG. 4, components corresponding to those shown in FIG. 2 are denoted by the same reference numerals and description thereof is omitted.
[0081]
In the symbol display circuit unit 107 in FIG. 4, since the forward voltage drop of the red light emitting diode and the forward voltage drop of the green light emitting diode are close to each other as described above, the difference in emission luminance is small. When it is desired to emphasize only the difference from the light emission luminance of the blue light emitting diode, a common drive voltage is applied to the red light emitting diode and the green light emitting diode. That is, the voltage dividing circuit 101 in the symbol display circuit unit 107 drives the drive voltage Eb for driving the blue light emitting diodes LB11 and LB12 and the green light emitting diodes LG11 and LG12 or the red light emitting diodes LR11 and LR12. Drive voltage Egr (<Eb) is output to the line L2 in the order of Eb, Egr, Egr, Eb,.
[0082]
Therefore, when driving the blue light emitting diodes LB11 and LB12, the drive voltage Eb is applied to the light emitting diodes LB11 and LB12 via the B transistor array 16 in which the line c is selected. Next, when driving the green light emitting diodes LG11 and LG12, the drive voltage Egr is applied to the light emitting diodes LG11 and LG12 via the G / R transistor array 17 in which the line b is selected. Further, when driving the red light emitting diodes LR11 and LR12, the drive voltage Egr is applied to the light emitting diodes LR11 and LR12 via the G / R transistor array 17 in which the line a is selected. In this way, the drive voltages are sequentially applied to the blue, green and red light emitting diodes, so that the light emitting diodes of the respective colors are sequentially turned on with substantially the same light emission luminance.
[0083]
  As shown in FIG.Reference exampleIn this case, the driving voltage of the blue light emitting diode and the green light emitting diode are made common, and two systems for switching between the driving voltage and the driving voltage of the red light emitting diode are provided, so that the circuit configuration is compared with the embodiment shown in FIG. Is slightly simplified.
[0084]
  The explanation aboveFruitIn the embodiment, the drive voltage is controlled so that the light emission brightness of each of the RGB light emitting diodes is the same, but it goes without saying that the light emission brightness of each light emitting diode can be made variable by changing the drive voltage.
[0085]
In the pachinko machine of this embodiment, the light emitting diodes of RGB of the symbol display 52 are controlled to be lit by the symbol display circuit unit 7, and the light emitting diodes are controlled to emit light with the same emission luminance. In addition, each of the RGB light emitting diodes of the decorative display 45 is also controlled to be turned on by the decorative display circuit unit 8. In this case, the light emitting diodes are also controlled to emit light with the same light emission luminance. Although the detailed circuit description of the decoration display circuit unit is omitted, the symbol display circuit unit 7 shown in FIG. 2 or the symbol display circuit unit 107 shown in FIG. 4 may be replaced with the decoration display circuit unit. Needless to say, the present invention is not limited to the light emission control of the light emitting diodes in the symbol display unit and the decoration display unit, and any light emitting diodes in the display unit of the gaming machine can be applied. Note that the present invention is not limited to pachinko machines but may be applied to slot machines and other gaming machines.

Since it can be switched and supplied to the light emitting diode, a gaming machine capable of controlling light emission of the multicolor light emitting diode easily and inexpensively can be provided.
