  The main board 700 includes a storage unit (not shown) composed of a semiconductor memory or the like in which a system program for managing the entire operation of the slot machine 100 and an execution program for a slot machine game are stored in advance, and a program for executing these programs. The illustrated microprocessor (MPU) is provided. An input port and an output port provided in the microprocessor and the remaining boards 300, 400, 500, 600, and 800 are connected by a wiring cable.

  In the sub control board 300, the mounted electric circuits are produced by the production speakers SR, SL, SW and the production lamps 103a, 104a, 104b according to the production control signal supplied from the microprocessor in the main board 700, Each of the effect display devices 103d is driven to function to perform an effect display appealing to the player's vision.

  The sub-control board 300 includes a temperature calculation unit 112, a determination unit 113, a drive voltage switching instruction unit 114, and a current limiting resistance switching instruction unit 110.

  The temperature calculation means 112 changes the electric resistance of the thermistor 122 arranged corresponding to the temperature that changes due to the heat generated during the light emission of each of the effect lamps 103a, 104a, 104b, the side lamp 106, and the back lamp 107. Calculate based on

  The determination unit 113 uses the temperature calculated (detected) by the temperature calculation unit 112 (detected temperature t (see step S4 in FIG. 6)) as a preset value (70 ° C. in step S4 in FIG. 6, step S6). (That is, whether or not the specified value has been reached), and the determination result is output to at least one of the drive voltage switching instruction means 114 and the current limiting resistance switching instruction means 110. To do.

  When the determination unit 112 determines that the detected temperature t has reached a specified value, the drive voltage switching instruction unit 114 is applied to illumination members such as the back lamp 107, the effect lamps 103a, 104a, and 104b, and the side lamp 106. A signal for reducing the drive voltage to be output is output to the drive voltage switching circuit 115. When the determination unit 113 determines that the detected temperature t has reached the specified value by the drive voltage switching instruction unit 114 and the drive voltage switching circuit 115, the drive voltage change that reduces the drive voltage to be applied to various illumination members. Means are configured.

  As will be described in detail later with reference to FIG. 5, the drive voltage switching circuit 115 is provided so that a plurality of different drive voltages set in advance can be applied to the illumination member. In this embodiment, the drive voltage is prepared so that +12 V and +24 V can be individually applied to the illumination member through different paths based on a transistor switching operation described later. Accordingly, when the drive voltage switching circuit 115 receives the signal from the drive voltage switching instruction unit 114, the drive voltage switching circuit 115 switches the path by a timely switching operation of the transistor, and uses + 12V or + 24V prepared in advance as the drive voltage. It can be applied to various illumination members.

  Further, the current limiting resistance switching instruction means 110, when the determination means 112 determines that the detected temperature t has reached a specified value, the illumination member such as the back lamp 107, the effect lamps 103a, 104a, 104b, and the side lamp 106. A signal to reduce the drive current to be supplied to the current limiting resistor switching circuit 120 is output. When the determination means 113 determines that the detected temperature t has reached the specified value by the current limiting resistance switching instruction means 110 and the current limiting resistance switching circuit 120, the current reduces the drive current to be supplied to various illumination members. Limiting resistance switching means is configured.

  As will be described later with reference to FIG. 5, the current limiting resistor switching circuit 120 includes a plurality of paths into which resistors having different electrical resistances are inserted so that current can be supplied to each of the illumination members. It is configured. Therefore, when the current limiting resistance switching circuit 120 receives the signal from the current limiting resistance switching instructing unit 110, the current switching resistance switching circuit 120 switches the path by a timely switching operation of the transistor, and different paths in which resistances of different electric resistances are inserted. By switching to, different drive currents can be supplied to various illumination members in a timely manner.

  Next, a specific configuration example of the drive voltage switching circuit 115, the current limiting resistor switching circuit 120, and the thermistor 122 is shown in FIG. In the figure, as elements connected to a state in which a signal from a CPU (Central Processing Unit) 111 in the sub-control board 300 can be received, a drive voltage switching circuit 115, a current limiting resistance switching circuit 120, a liquid crystal display device 103d, The speakers SR, SL, SW, the power supply device substrate 500, and the electric motor 118 are extracted and shown, but the other elements are not shown.

  In other words, the thermistor 122 is connected to the sub-control board 300 via the connector CN at one terminal and the other terminal. One terminal of the thermistor 122 is connected to an input port (not shown) of the CPU 111 through the connector CN and then connected to the power supply VCC via the pull-up resistor R1. The other terminal of the thermistor 122 is grounded via the connector CN.

  Next, the drive voltage switching circuit 115 and the current limiting resistance switching circuit 120 will be described as an integrated form in terms of the circuit configuration.

  That is, the circuit has an npn-type bipolar transistor Q4 as a switching element that cuts off / contacts the application of voltage on the drive voltage switching circuit 115 side, and has different drive voltages of + 24V and + 12V when the transistor Q4 is energized. It has a field effect transistor (FET) Q3 for switching. The transistor Q4 has a base connected to an output port (not shown) of the CPU 111, a collector connected to the gate electrode of the FET Q3, and an emitter grounded.

  In addition, the circuit includes an illumination member LP to which a driving voltage of + 24V or + 12V switched according to the driving state of the FET Q3 is to be applied, and any driving voltage is applied depending on the switching state of the FET Q3. In this case, npn bipolar transistors Q1 and Q2 for switching the drive current to be supplied to the illumination member LP are provided. In the present embodiment, the illumination member LP is an illumination member such as the back lamp 107, the effect lamps 103a, 104a, 104b, and the side lamp 106.

  The FET Q3 has a gate electrode connected to the collector of the transistor Q4, one electrode connected to the high-voltage power supply (+ 24V), and the other electrode connected to the low-voltage power supply (+ 12V) via the diode D1. Yes. Further, a resistor R3 of 10 kΩ, for example, is inserted between the gate electrode of the FET Q3 and the high-voltage power source. Furthermore, one terminal of the illumination member LP is connected to a connection node between the FET Q3 and the cathode of the diode D1, and the other terminal of the illumination member LP is connected to the collector of the transistor Q1. The collector of the transistor Q2 is connected to a connection node between the other terminal of the illumination member LP and the collector of the transistor Q1. Furthermore, the emitter of the transistor Q1 is grounded through a resistor R4 of 15Ω, for example, and the emitter of the transistor Q2 is grounded through a resistor R5 of 1 kΩ, for example.

  The transistor Q3, resistor R3, diode D1, etc. constitute a drive voltage switching circuit 115, and the transistors Q1, Q2, Q4, resistors R4, R5 etc. constitute a current limiting resistor switching circuit 120.

  In the driving voltage switching circuit 115 having the above configuration, for example, when the FET Q3 is energized in the energized state where the transistor Q4 is turned on, the illumination member LP is conducted to the high voltage side power source, and the driving voltage of + 24V is applied. Applied. On the other hand, when the transistor Q4 is turned on and the FET Q3 is turned off, + 12V low-voltage power is applied to the illumination member LP via the diode D1. Control of these transistors Q4 and FETQ3 is executed based on the signal transmitted from the drive voltage switching instruction means 114 to the drive voltage switching circuit 115 described above.

  In the current limiting resistor switching circuit 120, for example, when a driving voltage of + 24V is applied to the illumination member LP while the FET Q3 is energized, for example, the transistor Q2 is in a non-energized state and the transistor Q1 is in an energized state. A relatively large drive current corresponding to the resistance R4 of 15Ω flows through the illumination member LP. Thereby, the illumination member LP becomes a light emission state (high luminance state) at the time of normal control before the temperature rises (or after being raised and cooled). Similarly, when a driving voltage of + 24V is applied to the illumination member LP, if the transistor Q1 is in a non-energized state and the transistor Q2 is in an energized state, the illumination member LP is compared with a resistance R5 of 1 kΩ. A small drive current flows. Thereby, the illumination member LP will be in the light emission state (low-luminance state) in the control at the time of temperature rise.

  Next, the operation of the slot machine 100 will be described with reference to the flowchart of FIG. First, when power is turned on by the game hall staff, power supply from the power supply unit PWU to the corresponding part is started (step S1), and timely power supply to the lighting member LP is started. . In step S2, it is determined whether or not to end the game. Here, for example, when the player or the game hall clerk determines that the game is to end, the process jumps to step S8, and the power is turned off by the operation of the power supply board 500 by the game hall clerk.

  On the other hand, if it is determined in step S2 that the game is to be continued, the illumination member LP is brightly emitted as a normal state through the current path on the low resistance R4 side with the + 24V drive voltage applied. Lamp control 1 is executed (step S3). At this time, since the current limiting resistance switching circuit 120 switches to the current path on the low resistance transistor Q4 side in response to the signal from the current limiting resistance switching instruction means 110, the illumination member LP emits light with the highest luminance. It is in a state to get. And while playing a game in this state, the temperature of the said lighting member LP and its surroundings rises by the heat_generation | fever of the lighting member LP. Further, in step S4, the temperature calculation means 112 calculates the temperature based on the change in the electrical resistance of the thermistor 122 (detection temperature t), and the determination means 113 sets the detection temperature t to a preset specified value (for example, 70 ° C). As a result, if the detected temperature t does not exceed 70 ° C. (if it is 70 ° C. or lower), the process returns to step S2 and the process is repeated.

  On the other hand, if it is determined in step S4 that the detected temperature t has exceeded 70 ° C., the process proceeds to step S5 and the lamp control 2 is executed. That is, a signal is output from the drive voltage switching instruction unit 114 to the drive voltage switching circuit 115, and in response to this, the drive voltage switching circuit 115 switches the drive voltage to the + 12V side, and the luminance of the illumination member LP is increased. Reduce. At the same time, a signal is output from the current limiting resistance switching instruction means 110 to the current limiting resistance switching circuit 120, and the current limiting resistance switching circuit 120 switches the current path to the high resistance resistor R5 side, and thereby the luminance of the illumination member LP. Is further reduced. As a result, the temperature of the portion that has risen due to the heat generated during the light emission of the illumination member LP gradually decreases.

  Subsequently, in step S6, the temperature calculation unit 112 calculates the temperature, and the determination unit 113 compares the detected temperature t with a specified value (for example, 60 ° C.) this time. As a result, if the detected temperature t does not exceed 60 ° C., the process returns to step S2 and the process is repeated. On the other hand, if it is determined in step S6 that the detected temperature t has exceeded 60 ° C., it is determined in step S7 whether or not to end the game. If the player or the game hall attendant determines that the game is to end, the process proceeds to step S8, and the power is turned off by the operation of the power supply board 500 by the game hall attendant.

  Then, when an appropriate time required for cooling the portion that has risen due to heat generation has elapsed, the game hall staff manually opens the front door 101 and manually operates the power supply unit PWU to turn on the power again. The player can use the same slot machine 100 to continue the game.

  As described above, according to the present embodiment, even when the temperature rises due to heat generation of the illumination member LP, the drive voltage to be applied is driven by the drive voltage switching instructing unit 114 and the drive voltage switching circuit 115 when reaching the specified value. Since it can be reduced by the voltage changing means and the current limiting resistance switching means consisting of the current limiting resistance switching instructing means 110 and the current limiting resistance switching circuit 120, it is possible to reliably prevent the occurrence of an abnormal heat generation state exceeding the specified value. Can be avoided. As a result, it is possible to reliably avoid the adverse effects of the electronic components and the like mounted on the gaming machine when the temperature rises, and to expect the power consumption reduction effect associated therewith.

  In addition, since the drive voltage changing means includes a plurality of preset different drive voltages that can be applied to the illumination member LP, the drive voltage change means is prepared in advance when it is determined that the detected temperature t has reached the specified value. It is possible to quickly switch to another driving voltage, and therefore, it is possible to smoothly switch to a plurality of levels of brightness set in advance in consideration of lighting in the amusement store, etc. Can be done. And since the said current limiting resistance switching means is equipped with two electric current paths which interpose resistance R4, R5 which has different electrical resistance so that switching is possible with respect to the illuminating member LP, it determines with the detected temperature t having reached the regulation value. At this point, it is possible to quickly switch to another current path, and therefore, it is possible to smoothly switch to a plurality of levels of brightness set in advance in consideration of lighting in the game store. Furthermore, since the determination unit 113 sequentially determines whether or not the detected temperature t has reached the specified value based on a stepwise comparison with each specified value (70 ° C., 60 ° C.), control for suppressing the temperature rise. Can be implemented more finely.

  In each of the above-described embodiments, the present invention has been described by taking the slot machine 100 including the relatively small liquid crystal display device 103d on the front upper portion of the front door 101 as an example. Of course, the present invention may be applied to a slot machine provided with a so-called donut-shaped large-sized liquid crystal display device that covers substantially the entire front central portion of the front door 101 and has the central portion made transparent in a substantially rectangular shape. It is.
