When the pachinko machine 1 is used, the display panel 2
When the pachinko ball hit above enters a predetermined winning hole portion of the display panel 2, an operation start signal is input to the display device 3 from the control means of the pachinko machine 1 and the display device 3 starts operating.

The operation of the display device 3 is as follows: in all the display units 11, the stepping motor 13 is driven,
The rotary drum 21 rotates. Due to the rotation of the rotary drum 21, the upper edge of the display plate 22 located above the display position is disengaged from the stopper 23 and rotated downward in the forward direction. The subsequent display plate 22 rotated downward engages with the stopper 23,
While the display 21 rotates a predetermined angle, the following display plate 22 and stopper 23
The engagement state with is maintained, and thereafter, the succeeding display plate 22 is similarly disengaged from the stopper 23 and rotated downward in the forward direction.
Such an operation of each display plate 22 is continuously performed during the rotation of the rotary drum 21.

In the display plate 22 that engages with the stopper 23, the engagement piece portion 32 is in contact with the outer peripheral surface of the flange portion 26 of the rotary drum 21, and the display plate 22 and the display plate 22 are rotated as the rotary drum 21 rotates. The engaging piece portion 32 and the rotary drum 21 are more than the engaging position with the stopper 23.
When the contact position with and moves to the front, elasticity is imparted so that the upper side of the display plate 22 bends backward. Therefore, when the upper edge portion of the display plate 22 is disengaged from the stopper 23, the display plate 22 rapidly rotates forward and downward due to the elastic action, and the rear surface of the display plate 22 (the display window is rotated by downward rotation). The surface that faces 94) and the surface of the subsequent display panel 22 are instantaneously switched to the next pattern.

Therefore, while the rotary drum 21 is rotating, 1
The two patterns can be visually recognized as being displayed for a relatively long time, and can also be visually recognized as being instantaneously switched to the next pattern.

The rotation speed of the rotary drum 21 of each display unit 11 may be constant or different.

Then, when the user operates a stop button (not shown) or when a predetermined time elapses from the start of the operation, the stepping motor 13 of each display unit 11 is stopped, for example, in the order from the left side to the center and the right side.

The control unit for stopping each stepping motor 13 can grasp the stop position of the rotary drum 21 of each display unit 11, that is, the displayed pattern, so that the patterns of the three display units 11 match each other in a predetermined arrangement. It is judged whether or not it has become, and the judgment result is output to the control means of the pachinko machine 1.

As described above, the display device 3 includes the stepping motor 13 inside the rotary drum 21 of the leaf type display mechanism 12.
Since the stepping motor 13 is used to rotate and stop the rotary drum 21, the leaf type display mechanism 12 can be reliably operated, and the size and the structure can be simplified. Further, by supplying a minute hold current when the stepping motor 13 is stopped, the pattern can be reliably held at the stop position, and the pattern does not change even when vibration is applied.

Next, FIG. 10 to FIG. 12 show another embodiment. In this embodiment, the lamp 71 is provided at the front position of the opening 63 of the front case 53 and at both sides of each display unit 11.
Are arranged vertically. Therefore, instead of the reflector 72 of the above-described embodiment, the cover body 101 that supports each lamp 71 is used.

The cover body 101 is made of a translucent acrylic resin, and a mounting portion 102 to be mounted on the rear surface of the frame portion 64 of the front case 53 is horizontally formed in the upper and lower portions.
Lamp housing portions 103 are formed between the display units 11 so as to correspond to the positions on both sides thereof. This lamp compartment 10
The reference numeral 3 denotes a storage space 104 that projects forward from the mounting portion 102 and opens rearward to store the lamp 71 in a vertical posture.

By turning on each lamp 71, the lamp
The light 71 passes through the cover body 101 and is illuminated on the display plate 22 located at the display position.

Further, a lamp housing portion 10 having a built-in lamp 71
3 also functions as an isolation member that isolates the display plate 22 of each display unit 11 and a concealment member that conceals the gap between the display units 11 so that it cannot be seen from the front.

FIGS. 13 to 15 show other examples of pictures on the display board 22, respectively. In FIG. 13, a pair of upper and lower display plates 22 form a numerical picture. In FIG. 14, a numerical pattern is displayed on each of the upper and lower display boards 22. In FIG. 15, dice patterns are displayed on the upper and lower display plates 22.

Since the display unit 11 is constructed as one unit by integrally combining the leaf type display mechanism 12 and the stepping motor 13, it can be used by arranging as many as necessary. The display unit 11 can be shared.

Further, although the display device 3 is applied to the pachinko machine 1 in the above embodiment, it can be applied to a gaming machine such as a slot machine.
