Among them, the leaf display mechanism has the advantage that it is inexpensive compared to the dot matrix display element and can be made smaller than the rotary drum display mechanism.

A conventional leaf type display mechanism rotatably supports a plurality of display plates on the outer periphery of a rotating wheel having flanges at both ends, as disclosed in, for example, Japanese Patent Publication No. 57-8623. The rotating wheels are mounted in parallel on one rotating shaft so that they can rotate by frictional contact. When the rotating shaft is rotated by the motor, each rotating wheel is rotated by frictional contact with the rotating shaft.

A stop mechanism is provided for each rotating wheel, and each of the stopping mechanisms swings a lever by a solenoid and locks the lever to a ratchet gear provided on a side surface of the rotating wheel. Thus, the rotation of the rotating wheel is forcibly stopped with respect to the rotating rotating shaft.

The evacuation space where the shielding plate 82 that moves to the evacuation position is disposed behind the decorative plate 111 and below the decorative plate portion 113.
115 are formed.

Next, the operation of this embodiment will be described.

When the machine is set or the power is turned on, in all the display units 11, the stepping motor 13 is driven, and the rotation position detection sensor 44 detects the detection plate 30 of the rotating drum 21 to be rotated. Twenty-one rotation reference positions are detected. The rotation position of the rotating drum 21 is grasped by the control unit of the control circuit based on the rotation reference position, and the rotation of the stepping motor 13 is controlled.

The stop position of the rotary drum 21 is such that the intermediate portion of the adjacent support holes 29 is positioned corresponding to the vertical center of the display window 114, that is, the pair of upper and lower display plates 22 at the display position.
The drive stop of the stepping motor 13 is controlled so that the image faces the display window 114.

When the rotary drum 21 is stopped, the upper display plate 22 is locked by the stopper 23, and a pair of upper and lower display plates 22 located at the display position are vertically and planarly arranged. A pair of upper and lower display panels through the display window 114
One pattern is displayed with 22 as a set.

The shielding mechanism 81 includes a stepping motor.
After a certain period of time when the rotation of 13 stops and the upper display plate 22 is locked by the stopper 23 (after the lock, the display plate 22 is rotated and dropped, and is arranged in a substantially planar manner to form a pair of upper and lower patterns. After the time necessary for the operation), the shielding plate 82 at the retracted position is rotated to the shielding position by the solenoid 83, and the lower portion of the lower display plate 22 located at the display position is covered below the lower end of the lower display plate 22 by one. The front display panel 22b is shielded.

The light of the upper lamp 71a is reflected directly and on the horizontal reflector 73 and the vertical reflector 74, and illuminates the display plate 22 located at the display position. Lower lamp 71b
When the shielding plate 82 is in the retracted position, the light of
Similarly to the light of a, the light is directly and reflected to illuminate the display plate 22, and when the shield plate 82 moves to the shield position, it is diffused through the shield plate 82 and illuminated to the display plate 22.

When the pachinko machine 1 is used, the display panel 2
When the pachinko ball hit upward enters a predetermined winning hole portion of the display panel 2, an operation start signal is input from the control means of the pachinko machine 1 to the display device 3, 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 pivotally drops downward in the forward direction. Then, the subsequent display plate 22 engages with the stopper 23, and the rotating drum
While the display 21 rotates by a predetermined angle, the following display plate 22 and stopper 23
The engagement state with is maintained, and thereafter, the subsequent display plate 22 is similarly disengaged from the stopper 23 and pivotally drops downward in the forward direction. Such operation of each display plate 22 is continuously performed while the rotating drum 21 is rotating.

The display plate 22 engaged with the stopper 23 has the engagement piece 32 abutting on the outer peripheral surface of the flange portion 26 of the rotary drum 21. The engagement piece 32 and the rotating drum 21 are more than the engagement position with the stopper 23.
When the contact position moves forward, elasticity is imparted so that the upper side of the display plate 22 curves backward. Therefore, when the upper edge portion of the display plate 22 comes off the stopper 23, the display plate 22 suddenly turns forward and downward due to elasticity and falls downward. The next picture composed of the face facing the window 114) and the surface of the subsequent display panel 22 is instantly switched.

Therefore, while the rotating drum 21 is rotating, 1
The user can visually recognize that one of the patterns is displayed for a relatively long time, and can also visually recognize that the next pattern is instantly switched.

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

The shield plate 82 is configured to be driven in conjunction with the stop of the stepping motor 13 of each display unit 11. For example, the left stepping motor 13
Is stopped and the upper display plate 22 is locked by the stopper 23, after a certain time, the left shield plate 82 is moved from the retracted position to the shield position. During this time, the stepping motors 13 of the remaining central and right display devices 3 continue to be driven, and the rotating drum 21 integral therewith also rotates. This rotating drum 21
While is rotating, the center and right shield plates 82 are in the retracted position.

Then, after a certain period of time, the rotation of the right stepping motor 13 is stopped by a signal from a main control circuit of a pachinko machine (not shown), and the upper display plate 22 is locked by the stopper 23. After a lapse of time, the right shield plate 82 is moved from the retracted position to the shield position. During this time, the stepping motor 13 of the central display device 3 continues to be driven,
The rotating drum 21 integral therewith also rotates. While the rotary drum 21 is rotating, the central shielding plate 82 is in the retracted position.

Subsequently, after a certain period of time, the rotation of the central stepping motor 13 is stopped by a signal from the main control circuit of the pachinko machine (not shown), and when the upper display plate 22 is locked by the stopper 23, After a time, the central shielding plate 82 is moved from the retracted position to the shielding position.

It should be noted that this kind of pachinko machine detects that a pachinko ball has entered a predetermined winning hole (winning ball) and drives the display device 3. Therefore, next, each display unit 11 is stopped and the shielding plate 82 also keeps the shielding position until there is a winning ball.

Next, when there is a winning ball, the shielding plate 82 moves from the shielding position to the retreat position almost simultaneously from the right, center, and left, and the three rotating drums 21 start rotating. Have been. This state is the same when the player finishes the game, that is, when the so-called prize-holding ball ends, and when the pachinko machine starts to be started.

In the control unit for stopping each stepping motor 13, the stop position of the rotating drum 21 of each display unit 11,
That is, since it is possible to grasp which pattern is displayed, it is judged whether or not the patterns of the three display units 11 are in a predetermined arrangement such as matching, and the judgment result is output to the control means of the pachinko machine 1. It

By the way, in the display device using the conventional leaf-type display mechanism described in the above-mentioned publication, a ratchet gear rotating at high speed is securely locked at a predetermined position, and at the time of starting, it is retracted from the locked state. Is necessary, and a large torque locking mechanism is indispensable for each rotating wheel, the overall size becomes large, the structure becomes complicated, and each rotating wheel rotates due to frictional contact with the rotating shaft, so wear is caused The rotation operation is not reliable due to the occurrence of slippage.

On the other hand, the display device 3 of this embodiment is
Since the stepping motor 13 is arranged inside the rotary drum 21 of the leaf type display mechanism 12 and the rotary drum 21 is rotated and stopped by this stepping motor 13, the operation of the leaf type display mechanism 12 can be reliably performed, and it is small in size. The structure can be simple. Further, by supplying a small 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.

When the rotary drum 21 is stopped, the shielding plate 82
Moves forward near the lower end of the lower display panel 22 located at the display position, and covers below the lower end of the lower display panel 22 located at the display position to shield the immediately preceding display panel 22b. In addition, it is possible to make it easy to confirm the pattern of the display plate 22 at the display position, since a part of the design of the display plate 22b immediately before the lower display plate 22 does not overlap. Furthermore, the shielding plate 82
In terms of the movement of the player, the player can be impressed.

Further, the shielding plate 82 is
The rotary drum can be quickly moved to a shielding position that covers the lower part of the lower display plate 22 located near the lower end located at the display position and a retracted position that retreats from the vicinity of the lower end of the display plate 22.
It can also respond to fast rotation and stop of 21 operations.

Further, the light from the lamp 71b inside the shielding plate 82 is transmitted and diffused by the shielding plate 82 and illuminated on the display panel 22 to obtain a shielding effect and an illumination effect.

The outer surface 82a of the shielding plate 82 is processed into a V-groove shape,
The light from the LED 122 is scattered so that the outer surface 82a of the shielding plate 82 itself emits light so that the player can see it. The decorative effect can be enhanced by turning on, blinking or discoloring the LED 122.

A slide member 125 is attached to the plunger 91 of the solenoid 83, and a connecting arm 126 is provided on the upper front end of the slide member 125. The connecting arm 126 is connected to a lower arm 86 of the shielding plate 82. Therefore, below the space between the solenoid 83 and the shielding plate 82, a space for the components of the pachinko machine 1 is secured near the display window 114.

In each of the above embodiments, the shielding plate 82
It is also possible to enhance the decorative effect by directly attaching a light source to the surface of the panel, in which case the material of the shielding plate 82 may be an opaque substance.

Although the shielding plate 82 has been described as rotating about the support shaft 88, the displacement of the shielding plate 82 may be a sliding movement.

Although the solenoid 83 is employed as the electromagnetic driving means for the shielding mechanism 82, a general motor can be used. In this case, it is also possible to rotate or slide directly or via a transmission mechanism such as a gear.

Further, as the design of the display plate 22, examples of the design shown in FIGS. 19 to 21 can be applied. In other words, in FIG. 19, a pair of upper and lower display panels 22 constitute a numeric picture. In FIG. 20, a numerical pattern is displayed on each of the upper and lower display boards 22. In FIG. 21, a dice pattern is displayed on each of the upper and lower display boards 22.

Further, since the display unit 11 is configured as a single unit by integrally combining the leaf-type display mechanism 12 and the stepping motor 13, the required number of display units can be used side by side. The display unit 11 can be shared.

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.
