Description

  The present invention relates to a gaming machine, and more particularly to a technique for reducing the amount of heat generated from a power supply board used in the gaming machine.

A gaming machine such as a pachinko machine is provided with an effect device for performing an effect according to the gaming state. For example, a speaker for performing an effect by sound is provided.
The speaker is controlled by a sound control device. The sound control device includes a sound control circuit, a sound source IC, an amplifier (amplifier), and the like. The sound control circuit outputs a sound control signal corresponding to a main command signal (for example, a sound command signal) output from the main control circuit that controls the entire gaming machine to the sound source IC. The sound source IC outputs a sound signal corresponding to the sound control signal output from the sound control circuit. The amplifier converts the power source into a sound drive signal having an output waveform corresponding to the sound signal and outputs the sound drive signal to the speaker.
Normally, a gaming machine is provided with a power supply device that supplies power to each electric load. As the power supply device, for example, a power supply device that converts an AC24V power supply into a DC34V, DC12V, or DC5V power supply is used. The amplifier of the sound control device is supplied with DC12V power from this power supply device.
Conventionally, class A amplifiers and class B amplifiers are used as amplifiers for sound control devices.
However, the class A amplifier and the class B amplifier have a large loss. For this reason, the amount of power supplied from the power supply board to the sound control device increases, and the amount of heat generated by the power supply board increases.
In order to reduce loss in the amplifier, a gaming machine in which a class D amplifier is provided on a sound control board has been proposed. (See Patent Document 1)
JP 2002-355423 A

In recent years, there are many requests for multi-channel speakers and higher output in order to enhance the effect of sound. On the other hand, as the number of speakers increases and the output increases, the power consumption of the speakers increases and the capacity of the power supply device needs to be increased. When the capacity of the power supply device becomes large, not only the cost increases, but also a countermeasure against the temperature rise in the gaming machine due to the heat generated from the power supply board becomes important.
As a method for reducing the capacity of the power supply device, it is conceivable to use a class D amplifier as described in Patent Document 1. However, the method using the class D amplifier has a limit in reducing the capacity of the power supply device. Moreover, since the class D amplifier generates high-frequency switching noise, it is necessary to take measures against noise.

As the sound drive signal output circuit, a push-pull configuration in which two output elements are connected in series or a sound drive signal output circuit in a BTL (balanced transformer-less) configuration in which four output elements are bridge-connected is used. it can. Typically, a power amplifying element such as a transistor or FET is used as the output element, the power output from the voltage control circuit is input to the input terminal of the power amplifying element, and a sound signal is input to the control signal input terminal of the power amplifying element.

Thereby, the loss in the sound drive signal output circuit can be reduced as compared with the case where a power supply having a constant voltage is input to the sound drive signal output circuit. Therefore, the amount of heat generated from the control board can also be reduced.
Further, since the loss in the voltage control circuit provided to reduce the loss in the sound drive signal output circuit provided on the control board is small, the sound drive apparatus is changed from the power supply apparatus provided in the power supply board. It is possible to effectively reduce the amount of power required to drive the power source, and to effectively reduce the amount of heat generated from the power supply substrate on which the power supply device is provided.
Furthermore, since the sound drive signal output circuit outputs a sound drive signal corresponding to the sound signal, the switching noise is attenuated by the sound drive signal output circuit even when a switching regulator is used as the voltage control circuit. Therefore, unlike the class D amplifier, it is not necessary to take measures against switching noise.

Next, FIG. 2 shows a first embodiment of a sound driving device constituted by a voltage control circuit 144 and an amplifier 147.
In the present embodiment, two different types of transistors (NPN transistor 11 and PNP transistor 12) are connected in series between power supply terminals (input terminals) D and E, and connected to a connection point (output terminal A). A push-pull amplifier connected with a speaker 148 is used.
The output terminals of the differential amplifier 13 are connected to the bases (control signal input terminals) of the transistors 11 and 12. The sound signal Vin output from the sound source IC 146 is input to the non-inverting input terminal of the differential amplifier 13 via the delay circuit 15, and the sound driving signal Va output from the amplifier to the speaker 148 is input to the inverting input terminal. Are input via a detection circuit constituted by resistors 14a and 14b. The differential amplifier 13 outputs a difference signal between the signal input to the non-inverting input terminal and the signal input to the inverting input terminal to the bases of the transistors 11 and 12.
Thereby, the sound drive signal Va having a waveform corresponding to the waveform of the sound signal Vin is output from the output terminal A of the amplifier to the speaker 148.
In the present embodiment, the transistors 11 and 12, the differential amplifier 13, the resistors 14a and 14b, and the delay circuit 15 constitute an amplifier.

Switching regulators 20a and 20b are provided between the collectors (input terminals D and E) of the transistors 11 and 12 and the power source Vcc (for example, DC 12V power source output from the voltage converter 111), respectively. The switching regulators 20a and 20b correspond to the voltage control circuit 144 shown in FIG.
The switching regulator 20a includes a transistor 21a (switching element), a flywheel diode 22a, a coil 23a, a capacitor 24a, a differential amplifier 25a, an amplifier 26a, a half-wave rectifier circuit 27a, a reference voltage source, and the like.
The sound signal Vin is amplified by the amplifier 26a, and after the positive phase component (positive component) is extracted by the half-wave rectifier circuit 27a, the reference voltage V1 is added and input to the non-inverting input terminal of the differential amplifier 25a. The The output voltage of the switching regulator 20a (the voltage Vd of the input terminal D) is input to the inverting input terminal of the differential amplifier 25a. The differential amplifier 13 outputs a difference signal between the signal input to the non-inverting input terminal and the signal input to the inverting input terminal to the base of the transistor 21a.
Thus, the voltage Vd at the output terminal (amplifier input terminal D) of the switching regulator 20 is controlled to a value corresponding to the value obtained by adding the reference voltage V1 to the amplitude of the positive phase component of the sound signal Vin.
Here, the amplitude of the sound drive signal Va output from the amplifier to the speaker 148 is controlled by the differential amplifier 13 to a value corresponding to the amplitude of the sound signal Vin.
Therefore, the voltage V _CE between the input terminal D and the output terminal A of the amplifier, that is, the collector-emitter voltage of the transistor 11 is controlled to the reference voltage V1 by the switching regulator 20a.

The switching regulator 20b corresponds to a value obtained by adding the voltage Ve at the output terminal (amplifier input terminal E) of the switching regulator 20 to the negative phase component (negative component) of the sound signal Vin and the reference voltage −V1. The basic configuration is the same as that of the switching regulator 20a, except that the control is different.
Therefore, the voltage V _CE between the input terminal E and the output terminal A of the amplifier, that is, the collector-emitter of the transistor 12 is controlled to the reference voltage V1 by the switching regulator 20b.

Switching noise due to switching of the switching regulators 20a and 20b is input via the input terminals D and E.
However, in the present embodiment, the switching frequency of the switching regulators 20a and 20b is set to a frequency sufficiently higher than the sound frequency. Further, switching noise input to the input terminals D and E is attenuated between the collectors and emitters of the transistors 11 and 12.
Therefore, the switching noise mixed in the speaker wiring can be significantly reduced as compared with the class D amplifier.
In the present embodiment, the differential amplifiers 25a and 25b of the switching regulators 20a and 20b control the voltages of the input terminals D and E based on the sound signal Vin, that is, the input signal of the amplifier.
In this case, the control by the switching regulators 20a and 20b is delayed from the control by the differential amplifier 13 by an amplifier, a half-wave rectifier circuit, or the like. Therefore, in the present embodiment, the delay circuit 15 having a delay time corresponding to the control delay time of the switching regulators 20a and 20b is provided on the non-inverting input terminal side of the differential amplifier 13.

FIG. 3 shows the waveform of the sound drive signal Va output from the amplifier to the speaker 148 according to this embodiment.
As shown in FIG. 3, the sound drive signal Va has a waveform corresponding to the waveform of the sound signal Vin.
The difference V _CE of the amplitude of the voltage Ve and the sound drive signal Va of the voltage Vd and the input terminal E of the input terminal D of the amplifier is controlled to a constant value.
Thereby, the loss of the transistors 11 and 12 can be reduced compared to the loss of the class B amplifier.

In the sound drive device of the first embodiment, the switching regulators 20a and 20b control the voltages Vd and Ve of the amplifier input terminals D and E according to the sound signal Vin, that is, the amplitude of the amplifier input signal. is doing. Here, the amplitude of the sound drive signal Va output from the output terminal A of the amplifier is controlled to a value corresponding to the amplitude of the sound signal Vin. Therefore, it is possible to control the voltages Vd and Ve of the amplifier input terminals D and E according to the amplitude of the sound drive signal Va output from the amplifier.
In this case, the delay circuit 15 for compensating for the control delay of the switching regulators 20a and 20b provided in the first embodiment is not necessary.
FIG. 4 shows a second embodiment of the sound driving device that controls the voltage of the power source input to the amplifier based on the sound driving signal output from the amplifier.
In the present embodiment, as in the first embodiment, an amplifier in which two transistors (NPN transistor 31 and PNP transistor 32) are push-pull connected is used.
In the present embodiment, an amplifier is configured by the transistors 31 and 32, the differential amplifier 33, and the resistors 34a and 34b.
Similarly to the first embodiment, the differential amplifier 33 outputs a sound drive signal Va having a waveform corresponding to the waveform of the sound signal Vin from the output terminal A of the amplifier to the speaker 148.

The switching regulator 40a includes a transistor 41a (switching element), a flywheel diode 42a, a coil 43a, a capacitor 44a, a differential amplifier 45a, a reference voltage source, and the like.
A value obtained by adding the reference voltages V3 and V2 to the sound drive signal Va output to the output terminal A of the amplifier is input to the non-inverting input terminal of the differential amplifier 45a. The voltage Vd of the output terminal (amplifier input terminal D) of the switching regulator 40a is input to the inverting input terminal of the differential amplifier 45a. The differential amplifier 45a outputs a difference signal between the signal input to the non-inverting input terminal and the signal input to the inverting input terminal to the base of the transistor 41a.
As a result, the voltage Vd at the output terminal (amplifier input terminal D) of the switching regulator 40a is controlled to a value corresponding to the value obtained by adding the reference voltages V2 and V3 to the amplitude of the sound drive signal Va.
Therefore, as in the first embodiment, the switching regulator 40a, between the input terminal D and the output terminal A of the amplifier, i.e., the collector of the transistor 31 - the voltage V _CE is a reference voltage between the emitter (V2 + V3) Be controlled.
Switching regulator 40b includes a switching regulator 40a is, the amplitude of the sound drive signal Va at a positive collector of the transistor 31 - whereas the control to emitter voltage _{V CE} of the reference voltage (V2 + V3), the sound drive signal Va amplitude collector of the transistor 32 when the negative - only point of controlling the emitter voltage V _CE of the reference voltage (V2 + V3) are different, the basic configuration is the same as the switching regulator 40a.

When the switching regulator is controlled based on the amplifier output signal (sound drive signal Va having a waveform corresponding to the sound signal Vin), the switching regulator is controlled based on the amplifier input signal (sound signal Vin). There is no need to provide the delay circuit 15 of the first embodiment to be controlled.
However, when the amplitude of the sound drive signal Va abruptly changes, the response delay of the switching regulator 40,40b itself, the collector of the transistor 31 and 32 - reduces the emitter voltage _{V CE,} the transistor 31 and 32 May be saturated.
Therefore, in this embodiment, in order to prevent the transistors 31 and 32 from being saturated, a clamp circuit is provided for preventing the collector-emitter voltage V _CE from being lowered below a set value. In the present embodiment, a positive clamp circuit and a negative clamp circuit configured by unipolar operational amplifiers 35a and 35b that output current only in one direction are provided.
A signal obtained by adding the reference voltage V3 to the amplitude of the sound drive signal Va is input to the non-inverting input terminal of the operational amplifier 35a. The voltage Vd of the output terminal (amplifier input terminal D) of the switching regulator 40a is input to the inverting input terminal of the operational amplifier 35a.
As a result, when the voltage Vd at the output terminal D of the switching regulator 40a falls below the value obtained by adding the reference voltage V3 to the sound drive signal Va, the operational amplifier 35a supplies current to the terminal D, and the voltage Vd at the terminal D drops. To prevent it. When the voltage Vd at the output terminal D of the switching regulator 40a is larger than the value obtained by adding the reference voltage V3 to the sound drive signal Va, the clamp circuit does not operate.
The operational amplifier 35b constituting the negative side clamp circuit operates so that current flows from the terminal E.

In the first and second embodiments, a push-pull amplifier in which two output elements are push-pull connected is used. However, a BTL amplifier in which four output elements are connected in a bridge shape may be used. it can. The BTL configuration amplifier has a higher output power than a push-pull configuration amplifier, and a single power source can be used.
FIG. 5 shows a third embodiment of a sound driving device using an amplifier having a BTL configuration.
In the present embodiment, two different types of transistors (NPN transistor 51 and PNP transistor 52, NPN transistor 53 and PNP transistor 54) are connected in series between power supply terminals (input terminals) D1 and E1 and D2 and E2. By connecting the series circuits in parallel, and connecting the speaker 148 between the connection points (output terminals A and B) of the series circuits, the four transistors 51 to 54 are connected in a bridge shape. Yes.
The bases (control signal input terminals) of the transistors 51 and 52 are connected to the output terminal of an amplifier (normal phase amplifier) 55a. The bases (control signal input terminals) of the transistors 53 and 54 are connected to an inverting amplifier (reverse phase amplifier). ) 55b output terminal is connected.
The sound signal Vin output from the sound source IC 146 is input to the amplifier 55a and the inverting amplifier 55b. Thereby, the transistors 51 and 54 operate when the sound signal Vin is positive, and the transistors 53 and 52 operate when the sound signal Vin is negative. Therefore, the sound drive signal [Va−Vb] having a waveform corresponding to the waveform of the sound signal Vin is output to the speaker 148 connected between the output terminals A and B of the amplifier.
In this embodiment, the transistors 51 to 54, the amplifier 55a, and the inverting amplifier 55b constitute an amplifier.

Further, in this embodiment, the collector of the transistor 51 to 54 - as emitter voltage _{V CE} becomes the reference voltage, the transistor 51 through 54 respective input terminals D1, D2, E1, E2 power supply voltage to be input to the Switching regulators 56a to 56d for controlling the transistors 51 to 54 are provided.
As the switching regulators 56a to 56d, switching regulators having the same configuration as the switching regulators 40a and 40b shown in FIG. 4 can be used.
Although not shown, a clamp circuit similar to the clamp circuit on the reverse side and the clamp circuit on the reverse side shown in FIG. 4 is provided.

In the third embodiment, a switching regulator is provided for each output element of the amplifier. However, a common switching regulator may be provided for a plurality of output elements.
FIG. 6 shows a fourth embodiment of a sound driving device provided with a switching regulator corresponding to the output element on the power supply Vcc side and a switching regulator corresponding to the output element on the ground side.
In the present embodiment, a power supply side switching regulator 66a is provided between the power supply Vcc side input terminal D and the power supply Vcc, to which the power supply Vcc side transistors 61 and 62 are connected. , 64 is connected, and a ground-side switching regulator 66b is provided between the ground-side input terminal E and the ground.
As the switching regulators 66a and 66b, switching regulators having the same configuration as the switching regulators 40a and 40b shown in FIG. 4 can be used.
Further, a high level signal selector (HLS) 67a and a low level signal selector (LLS) 67b are provided for controlling the operating states of the switching regulators 66a and 66b.

The high level signal selector 67a selects and switches the sound drive signal having the higher level among the sound drive signal Va (normal phase signal) at the output terminal A and the sound drive signal Vb (reverse phase signal) at the output terminal B. -Output to regulator 66a. Thus, the switching regulator 66a allows the transistor 61 to operate based on the amplitude of the output terminal A sound drive signal Va when the transistor 61 operates based on the positive phase component of the sound signal Vin. Based on the amplitude of the sound drive signal Vb at the output terminal B, the voltage Vd at the power supply side terminal D is controlled.
Further, the low level signal selector 67b selects a sound drive signal having a smaller level of the sound drive signal Va (normal phase signal) at the output terminal A and the sound drive signal Vb (reverse phase signal) at the output terminal B. Output to the switching regulator 66b. Thereby, in the switching regulator 66b, when the transistor 64 is operated by the normal phase component of the sound signal Vin, the transistor 62 is operated by the reverse phase component of the sound signal Vin based on the amplitude of the sound drive signal Vb of the output terminal B. Sometimes the voltage Ve at the ground terminal E is controlled based on the amplitude of the sound drive signal Va at the output terminal A.

In the third and fourth embodiments, the full-wave waveform is always output by driving the output element on the power supply side and the output element on the ground side with a half-wave waveform having a phase difference of 180 degrees of the sound signal Vin. Configured. However, if a full-wave waveform is obtained when the waveforms output to the output terminal are superimposed, a desired sound can be generated from the speaker. In this case, for example, the output element on the power supply side and the output element on the ground side may be driven alternately by a half-wave waveform having a phase difference of 180 degrees of the sound signal Vin, and input to the output element to be driven. Only the voltage of the power supply needs to be controlled.
FIG. 7 shows a fifth embodiment of a sound driving device using one switching regulator.
In the present embodiment, a switching regulator 76 is provided between the input terminal D on the power supply Vcc side and the power supply Vcc, to which the transistors 71 and 73 on the power supply Vcc side are connected.
As the switching regulator 76, a switching regulator having the same configuration as the switching regulators 40a and 40b shown in FIG. 4 can be used.
Further, a high level signal selector circuit 77 similar to the high level signal selector circuit 67a shown in FIG. 6 is provided. As a result, the switching regulator 76 adjusts the amplitude of the sound drive signal with the larger amplitude of the sound drive signal Va (normal phase signal) at the output terminal A or the sound drive signal Vb (reverse phase signal) at the output terminal B. Based on this, the voltage Vd of the power supply side terminal D is controlled.
Although not shown, a clamp circuit similar to the clamp circuit shown in FIG. 4 is provided.

In the present embodiment, the full-wave waveform is formed by superimposing the half-wave waveforms. For this reason, crossover distortion may occur when half-wave waveforms are superimposed.
Therefore, in this embodiment, the sound signal Vin is configured to be output to the transistors 71 to 74 via the nonlinear amplifier 75.
The nonlinear amplifier 75 has input / output characteristics as shown in FIG. That is, when the amplitude of the input sound signal Vin is larger than Vin0, an output signal Vout having an amplitude obtained by multiplying the amplitude of the sound signal Vin by the amplification factor G is output. When the amplitude of the sound signal Vin is equal to or less than Vin0 and equal to or greater than -Vin0, an output signal Vout having an amplitude obtained by multiplying the amplitude of the sound signal Vin by an amplification factor [G / 2] is output. When the amplitude of the sound signal Vin is smaller than -Vin0, an output signal Vout having a substantially constant amplitude is output.
When the positive phase component of the sound signal Vin is input (when the positive phase signal Va is output), the non-linear amplifier 75 sets the base (control signal input terminal) side of the transistors 71 and 72 as positive, and the transistors 73 and 74 as positive. When the negative phase component of the sound signal Vin is input (when the negative phase signal Vb is output), the base (control signal input terminal) side of the transistors 71 and 72 is negative. Negative, the base (control signal input terminal) side of the transistors 73 and 74 is positive. That is, the transistors 71 and 74 operate when the positive phase signal Va is output, and the transistors 73 and 72 operate when the negative phase signal Vb is output.
Thereby, when the positive phase component (positive half wave) of the sound signal Vin is input to the nonlinear amplifier 75, the transistor 71 is driven according to the amplitude of the sound signal Vin by the output signal Vout, and the transistor 74 is On the other hand, when the negative phase component (negative half wave) of the sound signal Vin is input to the nonlinear amplifier 75, the transistor 73 is driven by the output signal Vout according to the amplitude of the sound signal Vin. Transistor 72 is grounded.
FIG. 9 shows waveforms of the sound drive signal Va (normal phase signal) at the output terminal A and the sound drive signal Vb (reverse phase signal) at the output terminal B of the present embodiment. As shown in FIG. 9, in the present embodiment, since the positive phase signal Va and the negative phase signal Vb overlap in the vicinity of the midpoint voltage, the signal [Va− Crossover distortion included in Vb] can be suppressed.

As described above, according to the present invention, it is possible to reduce the loss of an amplifier (sound drive signal output circuit) that outputs a sound drive signal that drives a sound generator as compared with a class B amplifier. Thereby, heat generation from the amplifier can be reduced, and the heat dissipation device can be eliminated or downsized. Therefore, it is possible to reduce the size of the substrate on which the circuit constituting the sound driving device is disposed.
Further, since the loss of the amplifier is reduced, the power supplied to the amplifier can be reduced. As a result, the capacity of the power supply circuit can be reduced, and the loss in the power supply circuit, and thus the heat generation amount of the power supply circuit can be reduced.
In particular, in the present invention, the power consumption of the amplifier is shared by the power supply circuit and the voltage conversion circuit. For this reason, it is possible to reduce the loss in the power supply circuit, and hence the amount of heat generated by the loss in the power supply circuit, compared to the case where the power consumption of the amplifier is borne by the power supply circuit. For example, when power is supplied from a power supply circuit with an efficiency of 88% to a speaker with power consumption of 31 W via a class B amplifier with a loss of 15 W, the loss in the power supply circuit is 6 W. On the other hand, in the present invention, the loss of the amplifier is 10 W, and the loss in the power supply circuit having an efficiency of 88% is reduced to 4.9 W.
Further, the power supply board on which the power supply circuit is disposed is attached to the gaming machine so that the gaming machine is positioned at the lower part in the vertical direction in order to supply power to each electric circuit. It is preferable. Here, if the power supply board is arranged at the lower part in the vertical direction, the heat generated from the power supply board is transmitted upward, and it is necessary to consider the influence of heat on other electric circuits arranged above the power supply board There is. For this reason, when there is much calorific value from a power supply board | substrate, it is necessary to devise the arrangement position of each board | substrate, or to provide a thermal radiation apparatus. In the present invention, since the amount of heat generated from the power supply substrate can be reduced, it is not necessary to consider the influence of heat generated from the power supply substrate. Thereby, a power supply board | substrate can be easily arrange | positioned to the perpendicular direction lower part.

By using the sound drive device described above, the amount of heat generated from the power supply board and the control device can be reduced.
However, the problem of temperature rise due to the amount of heat generated from the power supply board has not been completely solved. For this reason, by using in combination with the technology for radiating the heat generated in the power supply board, it is possible to more effectively prevent the temperature rise due to the amount of heat generated from the power supply board.
Next, the heat dissipation technique of the present invention will be described with reference to FIGS. Hereinafter, an embodiment configured as a pachinko machine will be described.

The reinforcing frame portion 207 is disposed horizontally in the left-right direction (the lateral width direction of the gaming machine) along the lower edge portion of the main body frame 203 and protrudes to the rear side of the main body frame 203 with a predetermined length.
The reinforcing member 207 on the lower edge side corresponds to the “main body frame constituting member” of the present invention.
Thus, an outflow space 208 having a predetermined height is formed above the power supply board box 210.
Further, since the power supply board box 210 and the heat radiation fins 211a are surrounded by the mounting plate 205, the prize ball control board box 220, the ball path component 270, and the reinforcing frame portion 207, a heat radiation space is secured. Is difficult.
Therefore, in the present embodiment, in order to further flow the air heated by heat radiation from the heat radiation fins 211a, a plurality of heat radiation holes (slits) 207a penetrating in the vertical direction are formed in the reinforcing member 207 on the lower edge side. is doing.

Here, if the main control board box 230 and the sub control board box 240 are directly attached to the game board 291, the flow of the air flowing upward through the heat radiation holes 207 a of the lower edge side reinforcing member 207 is hindered. .
Therefore, in the present embodiment, the first board box mounting base 292 and the second board box mounting base 293 are provided on the rear surface of the game board 291.
Then, when the main control board box 230 and the sub control board box 240 are viewed from the rear side of the pachinko machine 200 on the first board box mounting base 292, the main control board box 230 is behind the sub control board box 240 ( Wear it in a state of being stacked in the front-rear direction so that it is on the front side. Further, as viewed from the rear side of the pachinko machine 200, the sub-control board box 240 mounted on the front side is disposed so as to float from the rear surface of the game board 291 (arranged at a predetermined distance). The heat radiation space 296 is formed between the front surface of the sub control board box 240 and the rear surface of the game board 291.
A display control board box 260 in which the display control board 160 is housed is mounted on the second board box mounting base 293 with an appropriate distance from the game board 291.

A plurality of heat radiation holes (slits) 292b penetrating in the vertical direction are formed on the front side and the rear side of the flat plate portion 292a.
Thus, the air that has flowed upward through the heat radiation hole 207a of the reinforcing member 207 on the lower edge side is configured to flow into the heat radiation space 296 through the heat radiation hole 292b formed in the flat plate portion 292a.
Note that by arranging the flat plate portion 292a above the lower end of the game board 291, a relay space 295 having a predetermined height is formed between the flat plate portion 292a and the reinforcing member 207 on the lower edge side. Thereby, the air that has flowed from the outflow space 208 to the relay space portion through the heat radiation hole 207a of the reinforcing member 207 on the lower edge side easily flows into the heat radiation hole 292b of the flat plate portion 292a.

In addition, a display control board box 260 is attached above the heat radiation space 296 via a second board box mounting base 293 with an appropriate gap from the rear surface of the game board 291.

For this reason, a part of the air heated by the heat released from the radiation fins 211 a is discharged to the outside (rear) of the pachinko machine 200 even through the gap 209.

Further, the lower end side of the heat dissipating fins 211 a of the power supply board box 210 is configured to communicate with the lower space of the pachinko machine 200 through an out-ball discharge port 204 c formed in the ball passage constituting member 270.

Further, the lower end portion side of the radiating fin 211 a communicates with a lower space on the rear surface side of the main body frame 203 through a gap 206 between the rear end surface of the lower passage portion 204 b and the front surface of the payout control board box 220.
Thereby, the flow path for air to flow toward the said radiation fin 211a is ensured under the radiation fin 211a.

  As described above, in the present embodiment, air passages are formed by forming passages for air to pass above and below the radiating fins 211a, respectively. For this reason, the air that has been heated by the heat radiation action of the heat radiation fins 211a and has flowed upward is the upper outflow space 208, the heat radiation holes 207a of the lower edge side reinforcing frame portion 207, the relay space portion 295, and the first board box mounting base 292. After flowing to the rear surface of the game board 291 through the heat radiation hole 292b of the flat plate portion 292a, it is discharged from the heat radiation hole 280a of the protective cover 280 to the outside of the pachinko machine 200 through the heat radiation space 296. Along with this, air flows into the lower end portion side of the radiating fin 211a through the out ball discharge port 204c or the gap 206 between the out ball discharge port 204b and the payout control board box 220. On the other hand, the radiation fins 211a extend in the vertical direction, and the space between the adjacent radiation fins 211a constitutes an air flow path. Thus, a smooth and efficient air flow is formed, and the heat radiation effect of the heat radiation fins 211a can be improved.

  According to the present embodiment, as a result of improving the heat dissipation effect by ensuring the air permeability of heat dissipation of the power supply board box 210, the surface of the payout control board box 220 and the power supply board box 210 mounted on the main body frame 203 is As for the power supply board box 210 that does not have any problem even if it is not visually recognized, it can be arranged on the back side, while the surface of the payout control board box 220 that is likely to be fraudulent is visible. Arranging on the near side when viewed from the rear side of the pachinko machine 200 can suppress illegal acts such as modification and replacement of the control board. In addition, the two board boxes can be rationally arranged on the rear surface of the main body frame 203 with a small space.

  Further, in the present embodiment, the lower passage portion 204c located below the radiating fin 211a is formed in a bowl shape with the upper surface opened, and the out-sphere discharge port 204c is opened on the bottom surface of the lower passage portion 204b. It constitutes an air passage that penetrates vertically. Thereby, the ventilation function of the air with respect to the lower end part of the radiation fin 211a can be provided to the out ball discharge passage 204 without impairing the out ball discharge function. As a result, it is not necessary to make the space below the radiating fins 211a empty, and the rear space of the main body frame 203 can be used effectively.
