It should be noted that the number of drive current switching steps is not limited to the above two steps in both the manual luminance switching means 115 and the luminance adjusting means 114, and may be three or more stages.

  Next, with reference to FIG. 5, a specific example of a circuit for performing drive control on the illumination unit by the above-described illuminance measurement unit 112, determination unit 113, luminance adjustment unit 114, and manual luminance switching unit 115 will be described. . Here, description will be made assuming that LEDs D1 to D5 described later are provided in the effect lamp 103a.

  That is, as shown in FIG. 5, the circuit includes a plurality of (for convenience sake, five shown) LEDs D1 to D5, resistors Ra to Rj, and npn-type bipolar transistors Q1 to Q5 that constitute the effect lamp 103a. And pnp bipolar transistors Q6 to Q10, resistors Rk and Rm, and a path switch 129. The path changeover switch 129 operates in a state where the position changeover switch 128 is switched to the first changeover position A, and is connected to the voltage source VCC via the resistor Rm. For example, the resistors Ra to Re each have an electric resistance of 1.5 kΩ, the resistors Rf to Rj each have an electric resistance of 330 Ω, the resistors Rk have an electric resistance of 2 kΩ, and the resistors Rm An electric resistance of 10 kΩ can be used. The circuit is configured to be supplied with a voltage of + 12V.

  LEDD1 has an anode connected to a voltage source of + 12V via a resistor Rf and a transistor Q6, and a cathode grounded via a resistor Ra or a transistor Q1. LEDD2 has an anode connected to a voltage source via resistor Rq and transistor Q7, and a cathode grounded via resistor Rb or transistor Q2. LEDD3 has an anode connected to a voltage source via resistor Rh and transistor Q8, and a cathode grounded via resistor Rc or transistor Q3. LEDD4 has an anode connected to a voltage source via a resistor Ri and a transistor Q9, and a cathode grounded via a resistor Rd or a transistor Q4. LEDD5 has an anode connected to a voltage source via resistor Rj and transistor Q10, and a cathode grounded via resistor Re or transistor Q5.

  And each connection node of LEDD1-D5 and resistance Rf-Rj is connected to the predetermined | prescribed detection circuit so that the dispersion | variation in the voltage value of each conductive path resulting from the individual difference of several LED can be detected. . Further, each base of the transistors Q6 to Q10 has a predetermined value so that the drive pulse signal can be applied to the LEDs D1 to D5 in a feedback-controlled manner so as to keep the voltage value constant while changing the on / off duty ratio. Connected to the control circuit. In FIG. 5, the voltage values of the connection nodes of LEDs D1 to D5 and resistors Rf to Rj are V1 to V5, respectively, and the drive pulse signals applied to the bases of the transistors Q6 to Q10 are t1 to t5. .

Further, the bases of the transistors Q1 to Q5 are turned on when a base current is applied according to the switching operation of the path changeover switch 129, and the current path from the LEDs D1 to D5 via the resistors Ra to Re is changed to the low resistance current path side. It is connected to the brightness adjusting means 114 via the path switching switch 129 so that the light emission brightness of the LEDs D1 to D5 can be increased at the same time. Incidentally, in the case although not shown, the transistor Q1~Q5 is the position changeover switch 128 (FIG. 1, FIG. 2, see FIG. 4) is switched to the second switching position _{M L} or the third switching position _{M H} is path changeover switch 129 in response to the second switching position M _L in response to off, also in response to the switch 129 switched path corresponding to the third switching position M _H is turned on, a current path above Thus, it is configured to be switchable in two stages.

  Next, the operation of the slot machine 100 will be described. First, after the power is turned on by the game hall staff, the player executes a required game in the slot machine 100. That is, a game medal is inserted into the medal insertion unit MD, the start lever ST is pressed, and the spinning reels R1, R2, and R3 of the spinning reel device 200 are simultaneously rotated, and then the stop buttons SP1, SP2, and SP3 are pressed. Each press operation. Then, the spinning reels R1, R2, and R3 are sequentially stopped in response to the operation.

  When a special role such as a big bonus is won by repeating the above operation, various effects using lighting means such as the effect lamps 103a, 104a, 104b and the side lamps 106 are performed. At this time, for example, in the production lamp 103a, the drive current is supplied to the LEDs D1 to D5 via the transistors Q6 to Q10 that operate in response to the drive pulse signal and the resistors Rf to Rj.

  At this time, in the slot machine 100, the light receiving element 121 receives light emitted from the lighting in the game store, and the illuminance measuring means 112 measures the illuminance around the gaming machine main body (101, 102) based on the received light signal. Then, when the determining unit 113 compares the measured illuminance with a preset specified value and determines that the measured illuminance does not reach the specified value (that is, the lighting in the store is dark), the path changeover switch 129 is used. Without switching, the current paths of the LEDs D1 to D5 are kept switched to the resistors Ra to Re. Accordingly, the LEDs D1 to D5 (that is, the effect lamp 103a) emit light with the illuminance on the dark side of the two stages. On the other hand, when the determination unit 113 determines that the measured illuminance has reached the specified value (that is, the lighting in the store is bright), the determination unit 113 switches the path changeover switch 129 so that the current paths of the LEDs D1 to D5 are changed to the transistors Q1 to Q1. Switch to the Q5 side. Thereby, LEDD1-D5 light-emits with the illumination intensity of the bright side of two steps.

Incidentally, in a state where the position changeover switch 128 is switched to the second switching position M _L or the third switching position M _H, corresponding to the switching position of the position change-over switch 128 in response to the path changeover switch 129 on and off With the transistors Q1 to Q5 operating, the LEDs D1 to D5 perform an effect operation while switching their illuminance in two stages.

  As described above, according to the present embodiment, the illuminance detection means (121, 112) detects the illuminance around the gaming machine main body, and the brightness change means (114, 115) determines the LEDs D1 to D5 (for example, according to the detected illuminance). Since the light emission brightness of the effect lamp 103a) is changed, the light emission brightness at the time of effect by the illumination means equipped in the slot machine 100 is changed for each game shop or according to the illuminance that varies depending on the time zone in the same store. Therefore, it is possible to change the setting in a timely manner so as to adapt to the brightness of the game machine. Therefore, it is possible to reduce power consumption by a large number of gaming machines and to expect cost reduction.

Further, since the luminance changing means (114, 115) changes the drive current to the LEDs D1 to D5 in response to the switching operation by the position switching switch 128, the lighting means can be made to the player's preference by the switching operation of the position switching switch 128. It is possible to change the brightness accordingly. Further, since the brightness changing means (114, 115) is configured to be able to change the brightness to a plurality of levels step by step, the light emission brightness at the time of the lighting means is appropriately matched to the brightness in the amusement store. This makes it possible to make finer adjustments. Then, a plurality of switching positions of the position selector switch 128, a first switching position A for executing the automatic switching mode, and a second switching position M _L for performing manual switching low luminance mode, manual switching high brightness And a third switching position _MH for executing the mode. By switching the position changeover switch 128 at appropriate times, automatic adjustment of light emission luminance, manual switching to low luminance, manual switching to high luminance can be performed. Switching can be freely selected and executed according to the player's preference.
