2. Description of the Related Art As a gaming machine, a variable display device having a variable display portion whose display state can be changed is provided, and when a display result of the variable display portion becomes a predetermined specific display mode, the player is provided with a variable display device. Some are configured to shift to an advantageous specific game state. The variable display device includes a plurality of variable display units, and is generally configured to display the display results of the plurality of variable display units at different times. On the variable display section, for example, a plurality of identification information such as symbols are variably displayed. The fact that the display result of the variable display unit is a combination of predetermined specific display modes is usually referred to as “big hit”. In addition, the game value is a right to make the state of the variable prize ball device provided in the game area of the gaming machine advantageous for a player who is easy to win a hit ball, or a right for the player to be in an advantageous state. Or to generate.

[0003] When a big hit occurs, for example, a big winning opening is opened a predetermined number of times, and the state shifts to a big hit game state in which a hit ball is easy to win. Then, in each open period, when a predetermined number (for example, 10) of winning prizes is won, the winning prize opening is closed. The number of opening of the special winning opening is fixed to a predetermined number (for example, 15 rounds). An opening time (for example, 29.5 seconds) is determined for each opening, and if the opening time elapses even if the number of winnings does not reach a predetermined number, the winning opening is closed. If the predetermined condition (for example, winning in the V zone provided in the special winning opening) is not satisfied at the time when the special winning opening is closed, the big hit gaming state ends.

[0004] The progress of the game including the occurrence of a big hit is controlled by a microcomputer circuit for game control mounted on a game control board (main control board) installed on the back of the game board. Further, a lamp, an LED, a speaker, and the like for enhancing a game effect are installed on the game board surface or inside the frame. A board on which a circuit for performing the on / off control is mounted is also installed on the back of the game board. Also,

[0005] Solenoids for controlling the opening and closing of electric components such as lamps, LEDs, speakers, and the like, circuits mounted on each substrate, and variable winning ball devices such as a winning port are driven by DC power. In addition, a motor that performs hit ball firing and ball payout is often driven by DC power. Therefore, it is necessary to supply DC power to those game components. Further, it is necessary to supply DC power of different voltage according to the type of each game component. Therefore, the gaming machine is provided with a power supply circuit for generating a plurality of types of DC power from the AC power. Here, since the main control board controls the progress of the game, the number of signals exchanged with other boards is large. Therefore, a power supply circuit is also provided on the main control board, and DC power of various voltages is also supplied from the main control board to each board.

[0006]

If the types of lamps, LEDs, etc., and the various motorized objects provided on the game board surface and the frame side are different from each other, the driving voltage will be different. In some cases, the power supply circuit on the control board needs to be modified. In addition, when a board other than the main control board is changed due to a different model, if the voltage required for the changed board is also changed, it is necessary to remake the power supply circuit. That is, in the conventional gaming machine, it is necessary to reconfigure the power supply circuit when changing the model, and the power supply circuit cannot be reused. Further, when the power supply circuit is mounted on the main control board, the main control board cannot be reused. As a result, there is a limit in reducing the manufacturing cost of the gaming machine.

FIG. 10 is a block diagram showing a DC voltage supplied from the power supply substrate 150 to each substrate. As shown in FIG. 10, a power supply circuit 152 that generates various DC voltages is mounted on a power supply board 150. Then, the power supplied to each substrate is supplied via the power switch 151. Note that FIG. 10 shows only a DC voltage, but 24 V AC is also supplied to each substrate as needed.

In this embodiment, DC 30 V and DC 12 V are supplied to the main control board 31. The lamp control board 35 includes DC 30 V, DC 21 V and DC
12V is supplied. 30 V DC and 12 V DC are supplied to the prize ball substrate 37. The voice control board 70 includes
DC12V is supplied. Then, 30 V DC and 12 V DC are supplied to the launch control board 91. In addition,
The display control board 80 is connected to the DC through the main control board 31.
30V and 5V DC are supplied. As described below,
DC5V supplied to the display control board 80 is created in the main control board 31.

As shown in FIG. 10, the ground side of the voltage supplied to each substrate is shared by the power supply substrate 150. Therefore, the ground level in each substrate is common. Then, a voltage level can be used as it is as a signal transmitted from one substrate to another substrate. If there is a substrate whose ground level is not shared, when transmitting signals to such a substrate, it is necessary to use a non-contact type information transmitting means such as a photocoupler, which causes an increase in cost. However, when the ground levels of all the substrates are common as in this embodiment, it is not necessary to use a photocoupler or the like. In addition, since the power of each voltage from the power supply circuit 152 to each substrate is supplied through the power switch 151,
When a failure occurs in the gaming machine, power supply to all the boards can be stopped immediately.

Next, the operation of the gaming machine will be briefly described. FIG. 11 is a flowchart showing the main operation of the basic circuit 53 in the main control board 31. As described above, this process is started, for example, every 2 ms by the reset pulse generated by the periodic reset circuit 66. When the basic circuit 53 is started, the basic circuit 53 first performs a stack setting process for setting a designated address of a stack pointer (step S1). Next, an initialization process is performed (step S2). In the initialization process, the basic circuit 53 determines whether or not the power is turned on.
A process for initializing the AM 55 is performed. Further, various abnormality diagnosis processes are performed by the self-diagnosis function provided inside the pachinko gaming machine 1, and an alarm is issued if necessary according to the result (error process: step S3).

Next, a process for creating each judgment random number such as a big hit judgment random number is performed. Specifically, a process for updating a counter for creating each random number is performed (step S4). The basic circuit 53 further performs a process of creating a symbol random number (step S5). That is, a process of updating (adding 1) a random number or the like for determining a stop symbol of the symbol displayed on the variable display unit 9 is performed.

Next, the basic circuit 53 performs normal symbol processing (step S6). In normal symbol processing, variable display 1
A corresponding process is selected and executed according to a normal symbol process flag for controlling display of symbols displayed in 0 in a predetermined order. In addition, special symbol processing is performed (step S7). In the special symbol process, a corresponding process is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to a gaming state. Then, the value of the special symbol process flag is updated during each processing according to the gaming state.

Further, the basic circuit 53 performs a game effect process (step S8). In the game effect processing, the game effect L
Lamp processing for controlling lighting / extinguishing of the ED 28a, the game effect lamps 28b and 28c, and the decoration lamp 25, and voice processing for generating a predetermined sound from the speaker 27 in accordance with the progress of the game are executed. Next, the basic circuit 31 performs an external connection terminal process (step S9). In the external connection terminal processing, processing for transmitting data such as big hit information, start information, and probability variation information to the hall management computer via the information output circuit 64 is performed.

Next, the basic circuit 53 performs a prize ball process (step S10). In the prize ball processing, the basic circuit 53
The winning ball signal from the winning ball detection switch 99 is monitored.
When the winning ball signal is turned on, if the starting port switch 17 has been turned on, "6" is set in the winning ball number signal and sent to the winning ball substrate 37, and the count switch 23 or the V count switch 22 is turned on. If so, the prize ball number signal is set to "15" and sent to the prize ball substrate 37. If these switches are not turned on, the prize ball number signal is set to "10" and the prize ball is set. It is sent to the substrate 37.

Thereafter, the basic circuit 53 repeats the symbol random number generation processing of step S11 until a reset pulse is given from the periodic reset circuit 65 next time. That is, 1 is added to the value of each random number.

The DC12V is supplied to the winning ball count switch 123 and the ball lending count switch 124 in the ball payout device 97. A signal from each switch is input via the I / O port 371. Further, in this embodiment, the prize ball substrate 37 includes DC1

FIG. 17 is an explanatory diagram showing display control command data transmitted from the main control board 31 to the display control board 80. FIG. 18 is a block diagram showing a state of power supply in the display control board 80. As shown in FIG. 17, in this embodiment, the display control command data is transmitted from the main control board 31 to the display control board 80 through eight signal lines of the display control signals CD0 to CD7. Also,
A signal line for a display control signal INT for transmitting a strobe signal indicating output of display control command data is also provided between the main control board 31 and the display control board 80. Further, a supply line of 5 V DC serving as a power supply of the display control board 80 and a supply line of 30 V DC supplied to the variable display unit 9 and a signal line for supplying a ground level are also provided. Note that DC5V is generated by the DC-DC converter 69 on the main control board 31.

As described above, in this embodiment, DC5V, which is the power source of the IC on each board, is created on each board. When DC5V is generated by the power supply circuit 150 and supplied to each substrate, the DC5V power supply line is shared, so that noise is applied to the power supply line between the substrates and IC
May malfunction. However, if DC5V is generated on each substrate as in this embodiment, the possibility that the IC on the substrate malfunctions is greatly reduced.

The DC-DC converter as a low-voltage generating means provided on each substrate is composed of, for example, a regulator IC. However, it is only necessary to supply current to each IC on the substrate. It doesn't have to be big. Therefore, the calorific value is not so large. Therefore, it is not necessary to provide a heat radiating means such as a heat sink.

Since the power used by the display control board 80 is supplied via the main control board 31, it is possible to easily cope with a change in the configuration of the variable display section 9. In FIG. 18, CR
An example in which the variable display unit 9 using T is used has been described.
As shown in FIG. 19, when the variable display unit 9 using an LCD is used, for example, DC 12 V is supplied from the main control board 31 to the display control board 80. If the output terminals of both DC30V and DC12V are prepared on the main control board 31, when the type of the variable display section 9 is changed,
Although it is necessary to change the display control board 80, the hardware configuration of the main control board 31 does not need to be changed.

FIG. 20 is a block diagram showing an example of the configuration of the main control board 31 when the variable display unit 9 of the drum type is used. In this example, the drum motors 141, 142, 143 for rotating the drum are driven at DC 30V.

It is assumed that the heaters 142a, 143a are driven at 24 VDC and the heaters 141b, 142b, 143b for heating the drum lamps 141a, 142a, 143a are driven at 5.4V DC. In such a case, a DC-DC converter 801 is provided on the main control board 31, and the DC-DC converter 801 uses the DC-DC converter 801.
Can be configured to create

According to such an embodiment, the power supply board 150 has a voltage of 30 V DC, 21 V DC and 12 V DC.
V, or only DC30V, DC21V, DC12V and DC7V need to be created.
It can be shared with those using T or LCD. In the power supply board 150, DC 24V and DC
When all voltages including 5.4V are created, in the gaming machine using the variable display unit 9 by CRT or LCD, DC2
Since 4 V and 5.4 V DC are not used, an empty terminal will occur. However, if the DC 24 V and DC 5.4 V are generated in the main control board 31 in this manner, the power supply board 15 having no empty terminals and reduced cost can be realized.
0 can be commonly used in each model. Further, such a power supply substrate 150 is miniaturized. In the configuration shown in FIG. 20, the drum motors 141, 142, 143, and the like are driven by the sub CPU 820 for display control and the drive circuit 830.

In the above embodiment, the main control board 31,
Lamp control board 35, prize ball board 37, voice control board 70
The DC-DC converters 69, 359, 379, 709, and 919 mounted on the emission control board 91 generate 5 VDC from 12 VDC from the power supply board 150. However, the power supply circuit 152 in the power supply board 150 is DC1
A voltage other than 2V is created, and each substrate is set to DC
5V may be created.

FIG. 21 is a block diagram showing an example in which the power supply circuit 152 in the power supply board 150 creates DC 30V, DC 21V, DC 12V and DC 7V, and each board creates DC 5V from DC 7V. The DC 12 V is used for amplifying the volume of the speaker 27 in the audio control board 70. Then, a large current flows at the time of volume amplification, and the voltage value of DC12V may fluctuate. Therefore, when generating DC5V from DC12V, the fluctuation of DC12V may appear as noise of the 5V power supply. However, in the power supply board 150,
If a voltage different from DC12V is created, and if DC5V for driving the IC is created on each substrate based on the voltage, a more stable 5V power supply can be created.

As described above, in each of the above embodiments,

The power supply board 150 installed at a predetermined position on the frame 2A side is collectively created and supplied to each board. In the example shown in FIG. 2, the predetermined position is the upper right side of the back surface of the frame 2A.
Therefore, when the model is changed, it is not necessary to replace the power supply board 150, and the cost can be reduced and the life of the board can be extended. In addition, since the voltages used in each substrate are collectively created on the power supply substrate 150, the DC
It is not necessary to install a DC-DC converter for producing the same voltage other than 5 V on each substrate. Further, according to the present invention, there is also an effect that heat generation in each substrate is reduced. Further, among the voltages used in each substrate, the IC driving voltage is created in each substrate, so that IC malfunction is prevented.

Since the voltages used in each board are collectively created in the power supply board 150, the amount of heat radiation in each board is surely reduced as compared with the conventional gaming machine. Therefore, there is also an effect that the measures for heat radiation in each substrate or substrate housing (substrate box) can be simplified. Further, as shown in FIG. 2, since the information terminal plate 160 is provided in a layer on the power supply substrate 150, the area of the back surface of the gaming machine is effectively utilized.

The board configuration (the main control board 31, the lamp control board 35, the prize ball board 3) in each of the above embodiments is described.
7, the voice control board 70 and the launch control board 91), ie, the configuration of each control means is an example, and the present invention can be applied even when another configuration according to the form of the gaming machine is adopted. it can.

[0072]

As described above, according to the present invention, the game machine is provided with power supply creating means for creating a plurality of necessary voltages from electric power supplied from the outside and supplying the required voltages to each control means. However, since the power supply circuit is formed separately from each control means and installed at a predetermined position on the frame side, the power supply circuit can be shared between the models, thereby reducing the manufacturing cost and extending the life of the substrate. This has the effect of reducing heat generation in each control means.

When each control means has low voltage generating means for generating its own low voltage for driving the IC from the medium voltage supplied from the power generating means, the influence of noise on the power supply for driving the IC is reduced. Can be prevented. Further, when the power of the variable display control unit is configured to be supplied via the game control unit, it is possible to easily cope with a change in the type of the variable display unit. When the power supply creating means is configured to include at least a switching means for stopping power supply to each control means, it is easy to deal with a failure in the gaming machine.
