Has a printed wiring (not shown) printed at a predetermined position on its surface to form a printed circuit board.

A motor (not shown) is attached to the holding plate 65. The drive shaft of this motor is the rotary drum 62.
The rotary drum 62 is rotated in the circumferential direction when the motor is rotationally driven.
A backlight 67 is provided inside the rotary drum 62. The backlight 67 is attached to the holding plate 65 so that the light projecting surface 67 a faces the inner peripheral surface of the rotating drum 62. Projection surface 67a of the backlight 67
Is a curved surface along the inner peripheral surface of the rotating drum 62, and a large number of light emitting diodes (not shown) are arranged. The peripheral surface of the rotary drum 62 facing the light projecting surface 67a is brightly illuminated by the light emission of these many light emitting diodes.

A connector (not shown) is attached to the holding plate 65. This connector is connected to a motor (not shown) and a backlight 67 via a printed wiring printed on the surface of the holding plate 65, a wiring attached to the holding plate 65, and the like.

In this embodiment, with the display unit 60 attached to the game board 41 (FIG. 4), each rotating drum 62 is rotated in the direction shown by the arrow A in FIG. The numbers "1" to "6" drawn on the outer peripheral surface of each rotary drum 62 are variably displayed from the top to the bottom at the display position 52L and the display position 52R on the right. Alternatively, by rotating at least one of the rotary drums 62 in the direction opposite to the arrow A, the respective numbers “1” to “6” may be variably displayed from bottom to top.

The main body casing 61 has a frame shape including an upper plate 61a, a lower plate 61b, a left side plate 61c, and a right side plate 61d, and each holding plate 65 is fitted in the main body casing 61. At both ends of the upper plate 61a and the lower plate 61b,
A mounting portion 69 for fitting the holding plate 65 is provided in a protruding manner. Each mounting portion 69 extends in the front-rear direction, and the cut groove 70 extends in the front-rear direction. The upper side and the lower side of each holding plate 65 are fitted into the corresponding cut grooves 70 from the back side. Then, each holding plate 65 is slid to the front side, so that the front side thereof is received by the groove end of the cut groove 70 and is mounted in the main body casing 61. In the state where each holding plate 65 is mounted inside the main body casing 61, the interval between the rotary drums 62 is substantially equal to the width of the dot display 63.

The dot display 63 has, for example, a semi-cylindrical shape, and its outer peripheral surface has a curvature substantially equal to that of the outer peripheral surface of the rotary drum 62. Since the dot display 63 is formed in a semi-cylindrical shape, a semi-cylindrical space can be secured on the back side of the dot display 63. Thereby, for example, the wiring or the like can be accommodated in the space, so that the space can be effectively used.

An accommodating recess 73 for accommodating a not-shown mounting piece of the dot display 63 is formed at the substantial center of the upper plate 61a and the lower plate 61b so as to project outward.
When the two rotating drums 62 and the dot indicators 63 are mounted inside the main body casing 61, they are adjacent in a row with the dot indicators 63 sandwiched between the two rotating drums 62, and their outer peripheral surfaces are They are almost flush with each other.
As a result, the display of the dot display 63 is displayed on the rotary drum 62.
Since it is possible to have a perspective as in the case of, the discomfort of the display mode can be reduced.

At the front edges of both ends of the upper plate 61a of the main body casing 61 and the front edges of the lower ends of the left and right side plates 61c, 61d, mounting portions 80 for mounting the display unit 60 on the game board 41 are projected. ing. Two mounting holes 81 are formed in each mounting portion 80, and a screw is passed through these insertion holes 81 and screwed into a screw hole (not shown) formed on the back side of the game board 41, thereby displaying the display unit. 60
Is attached to the game board 41.

The light emitting diode of the symbol display 52 in the gaming machine having such a configuration is controlled by the lighting control circuit section E shown in FIG. This lighting control circuit unit E controls the switching of the cathode side of the light emitting diode, so that even when the light emitting diode of the symbol display 52 is added, the size of the sub CPU, the control port, the control program, etc. are not increased. This can be dealt with with a simple circuit configuration, and thus lighting control can be realized at low cost.

The lighting control circuit portion of the present embodiment is applied to control the light emitting diode of the symbol display,
The invention is not limited to this, and may be applied to the control of the light emitting diode of the decoration display and other light emitting diodes of the display unit.
Further, in the present embodiment, the lighting control circuit unit is applied to a pachinko machine, but needless to say, the present invention can be applied to a gaming machine such as a slot machine. Further, although the light emitting diode is described as the light emitting element in the present embodiment, the EL element may be used without being limited thereto.
