Abstract

PROBLEM TO BE SOLVED: To prevent a pictorial pattern from becoming worn out by forming a protruding part which prevents the edge on a free end side of a display plate from coming into contact with another display plate located before or after the former, on at least, one of the free end sides of each of the display pates, in a leaf-type motor-driven accessory consisting of the plural display plates supported, in freely rotatable manner, on the outer periphery of a rotary drum on a cylinder. SOLUTION: When a power supply is turned ON, a rotary drum 21 is rotated by a stepping motor 13, and the rotary reference position of the rotary drum 21 is detected by a rotary position detecting sensor 44 collaborating with the detecting plate part 30 of the rotary drum 21. In addition, when the rotary drum 21 is rotated, plural display plates 22 suspended in a stepped arrangement manner are swung depthwise, so that the lower edge on a free end side of the display plate 22 at a higher position tends to come into contact with the pictorial pattern part of the display plate 22 at a lower position. Therefore, a protruding part 22a is formed on the part where a pictorial pattern is not drawn is formed on the tip of a free end side of the display plate 22. Thus it is possible to prevent the whole lower edge of the display plate 22 from coming into contact with the pictorial pattern and thereby the pictorial pattern from becoming worn out.

2. Description of the Related Art A conventional leaf type electric accessory has a plurality of display plates rotatably mounted on the outer circumference of a rotary drum having flanges at both ends, as disclosed in, for example, Japanese Patent Publication No. 57-8623. The plurality of rotary drums are mounted in parallel on one rotary shaft so as to be frictionally contactably rotatable. By rotating this rotating shaft with a motor, each rotating drum is rotated by frictional contact with the rotating shaft.

Further, a stop mechanism is provided for each rotary drum, and each stop mechanism causes a solenoid to swing a lever, and the lever is locked to a ratchet gear provided on the side surface of the rotary drum. As a result, the rotation of the rotating drum is forcibly stopped with respect to the rotating rotating shaft.

Then, when the rotating wheel is stopped, the upper display plate of the pair of upper and lower display plates forming the display surface is locked by the stopper at the display position. Therefore, the pair of upper and lower display plates located at the display position are arranged in a plane, and one picture is displayed with the pair of upper and lower display plates as one set.

As described above, the three display units 11 and
The display device 3 is configured by combining the case 51 and three shielding mechanisms 81. An opening 101 is formed at the position where the display device 3 of the display board 2 is mounted, and a plurality of mounting bosses 102 are formed on the back surface of the edge of the opening 101.
The display device 3 is mounted on the rear surface of the display panel 2 by screwing the mounting flange 61 of the front case 53 to the mounting boss 102.

A decorative plate 111 is attached to the opening 101 of the display panel 2. The decorative plate 111 has a fitting portion 112 which is fitted into the opening 101 from the front, and a decorative plate portion 113 which is slightly curved in the vertical direction is formed inside the fitting portion 112. The plate portion 113 is formed with a display window 114 having a size such that a pair of upper and lower display plates 22 located at display positions corresponding to the respective display units 11 can be visually recognized from the front. 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, the rotation position detection sensor 44 detects the detection plate portion 30 of the rotating drum 21 that is driven by the stepping motor 13 in all the display units 11 to rotate the rotating drum 21. The reference position is 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.

When the rotary drum 21 is rotated, the plurality of display plates 22 that hang downward in different steps are swayed in the front-rear direction.
Since the lower edge of the free end side comes into contact with the picture part of the display plate 22 at the lower position, the design may be worn, but at the free end side tip of the display plate 22 as in the present invention, Moreover, since the protrusion 22a is formed in the portion where the picture is not extracted, the protrusion 22a of the display plate 22 in the higher position abuts the portion in the lower position where the picture is not extracted.

Therefore, the entire lower edge of the display plate 22 does not come into contact with the design, so that the design is not worn and the design is kept in a beautiful state for a long period of time.

The stop position of the rotary drum 21 is such that the middle portion of the front and rear support holes 29 is located 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.

In the state where the rotary drum 21 is stopped, the projection 22a of the upper display plate 22 is locked by the stopper 23, and the pair of upper and lower display plates 22 positioned at the display position are vertical and planar. One picture is displayed from the front through the display window 114 with the pair of upper and lower display plates 22 as one set.
At this time, the display panel 22 on the upper side is
Since the pattern is held by a, the pattern is not obscured by the stopper 23 so that the pattern is not obscured, and the entire pattern is visible and looks good.

The shielding mechanism 81 is 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 from the upper lamp 71a is reflected directly and by 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 a, the light is illuminated on the display panel 22 directly and reflected, and when the shielding plate 82 moves to the shielding position, the light is diffused through the shielding plate 82 and illuminated on the display plate 22.

When the pachinko machine 1 is used, the display board 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 rotating drum 21 rotates. Due to the rotation of the rotating drum 21, the upper edge of the display plate 22 located above the display position is disengaged from the stopper 23, and is rotated forward and downward to fall.

Then, while the succeeding display plate 22 engages with the stopper 23 and the rotating drum 21 rotates by a predetermined angle, the engagement condition between the succeeding display plate 22 and the stopper 23 is maintained, and thereafter, similarly. The subsequent display plate 22 is 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.

In the display plate 22 that engages with the stopper 23, the engaging 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 moves forward, elasticity is imparted so that the upper side of the display plate 22 curves backward.

Therefore, the upper edge of the display board 22 is stopped by the stopper 23.
When the display plate 22 is disengaged from the display plate 22, the display plate 22 suddenly rotates forward and downward due to the elastic action, and the back surface of the display plate 22 (the surface facing the display window 114 by the downward rotation) and the subsequent display plate 22 are separated. Instantly switch to the next pattern consisting of the surface.

Further, the locking piece portion of the display plate 22 located on the lower side
Since 32 abuts on the outer peripheral surface of the flange portion 26 of the rotary drum 21, the lower display plate 22 in the display state does not shake, and the player can clearly confirm the pattern.

Therefore, while the rotary 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 rotary drum 21 of each display unit 11 may be constant or different.

Further, the shield plate 82 is configured to be driven in association 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 remaining stepping motors 13 of the central and right display devices 3 continue to be driven, and the rotary drum 21 integrated with the stepping motors 13 also rotates. While the rotary drum 21 is rotating, the central and right shield plates 82 are in the retracted position.

Then, after a certain time, when the rotation of the right stepping motor 13 is stopped by the signal from the main control circuit of the pachinko machine (not shown), and the upper display plate 22 is locked by the stopper 23, it is kept constant. 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.

The pachinko machine of this type drives the display device 3 by detecting that a pachinko ball has entered a predetermined winning hole (winning ball). Therefore, until the next winning ball is present, each display unit 11 is stopped, and the shielding plate 82 also keeps the shielding position.

Next, when there is a winning ball, the shield plate 82 is moved from the shield position to the retracted position at substantially the same time for all three of the right, center, and left, and the three rotary drums 21 start to rotate. Has been done. 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 section for stopping each stepping motor 13, the stop position of the rotary drum 21 of each display unit 11,
That is, since it is possible to grasp which pattern is displayed, it is determined whether or not the patterns of the three display units 11 are in a predetermined arrangement such as coincidence, and the determination result is output to the control means of the pachinko machine 1. You.

By the way, in the display device using the conventional leaf type display mechanism described in the above publication, the ratchet gear rotating at a high speed is reliably locked at a predetermined position and is retracted from the locked state at the time of starting. It is necessary to have a large torque locking mechanism for each rotating car, which makes the entire size larger and the structure more complicated, and each rotating car rotates due to frictional contact with the rotating shaft, which causes wear. The rotation is not reliable due to the occurrence of slippage and slippage.

On the other hand, the display device 3 of this embodiment is
The stepping motor 13 is arranged inside the rotary drum 21 of the leaf display mechanism 12, and the rotation and rotation of the rotary drum 21 are performed by the stepping motor 13, so that the operation of the leaf display mechanism 12 can be reliably performed. The structure can be simplified. 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.

Moreover, when the rotary drum 21 is stopped, the shield 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
From the aspect of the movement of the player, the player can be given a favorable feeling.

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. Also,
The light from the lamp 71b inside the shield plate 82 is transmitted and diffused by the shield plate 82 and illuminated on the display plate 22, so that the shielding effect and the illumination effect can be obtained.

Next, a second embodiment of the present invention will be described with reference to FIGS. The same structures as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In this embodiment, the lamp 71c is provided at the front position of the opening 63 of the front case 53 so as to correspond to both side positions of each display unit 11.
Are arranged vertically. Therefore, instead of the reflector 72 of the first embodiment, each lamp 71c
A cover body 116 for supporting the is used.

The cover body 116 is made of a translucent acrylic resin, and an attachment portion 117 attached to the rear surface of the frame portion 64 of the front case 53 is formed in the upper and lower portions in a horizontally long shape.
Lamp storage sections 118 are formed between the display units 11 at both sides thereof. This lamp compartment 11
8 has a storage space 119 that protrudes forward from the mounting portion 117 and opens rearward in the inside to store the lamp 71c in a vertical posture.

When the lamps 71c are turned on, the light from the lamps 71c is transmitted through the cover body 116 and illuminated on the display plate 22 located at the display position. Further, the lamp housing 118 having the lamp 71c built therein also functions as an isolating member that isolates the display plate 22 of each display unit 11 and a concealing member that conceals the gap between the display units 11 from the front.

Next, in the present invention, it is possible to further develop the above embodiment, and a third embodiment thereof will be described with reference to FIG.
This will be described with reference to FIGS. Note that the same reference numerals are used for the same structures as those in the above-described embodiment, and the description thereof is omitted.

The difference from the above-mentioned embodiment is that, instead of the engaging piece portion 32 of the display plate 22, a protrusion 26a is provided on the inner wall of the flange portion 26 of the rotary drum 21, and this protrusion 26a causes the upper display at the display position. The plate 22 is prevented from tilting backwards.

That is, when the rotary drum 21 is stopped, the front surface of the display plate 22 displayed on the surface on the shaft support side abuts the protrusion 26a, so that the upper display plate 22 is prevented from tilting backward. At the same time, the lower display plate 22 is prevented from swinging in the front-back direction. Therefore, the upper display plate 22 is instantaneously switched and the lower display plate 22 is also stopped without shaking, so that the player can instantly recognize the pattern.

The rotational position detecting sensor 44 is arranged inside the stepping motor 13 for driving the drum. In the front case 53 and the rear case 52, the storage space of the leaf type display mechanism 12 is formed in a cylindrical shape, and the diameter thereof is set to such a degree that each display plate 22 can be rotated in a state of being tilted toward the center side of the rotating drum 21. , Miniaturized.

A stopper is provided above the opening 63 of the front case 53.
23 is integrally formed, and the stopper 23 prevents the upper display plate 22 from tilting forward at the display position. Note that, compared to the above embodiment, the stopper 23 is
Has a long distance from the rotation axis, and has no function of giving elasticity to the display plate 22 at the display position.

A guide portion 121 is formed below the opening 63 of the front case 51 so that the front end of the display plate 22 fed from the display position abuts and guides the tip of the display drum 22 so as to fall toward the center of the rotary drum 21. . As the light source arranged below the opening 63 of the front case 51, a plurality of LEDs 122 emitting two colors are used.

The shield plate 82 is integrally formed with levers 84 on both sides, and a bearing portion 85 having a support shaft 88 is formed in the middle of each lever 84 so as to project therefrom.
1 is rotatably supported by a shaft support member 123. A prism 124 is formed between the levers 84 so as to face the inner surface 82b of the shielding plate 82, and a lower arm 86 is formed on one of the levers 84. Then, the light from the LED 122 is guided to the shielding plate 82 by the prism 124.

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 above the front end of the slide member 125, and the connecting arm 126 is connected to the 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 shield 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. Further, although the shield plate 82 has been described as rotating about the support shaft 88, the shield plate 82 may be displaced by sliding.

Further, although the solenoid 83 is adopted as the electromagnetic drive means in the shielding mechanism 82, a general motor can also 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, the examples of the designs as 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, 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 base 1 in the above-mentioned embodiment, it can be applied to electric role machines such as slot machines.

[0075]

As described above, according to the present invention, since the protrusion is formed at the free end of the display plate and in the portion where the pattern is not extracted, the protrusion of the display plate at the high position is formed. Will come into contact with the portion of the lower position where the picture is not extracted, and therefore the entire lower edge of the display plate will not come into contact with the picture, and the picture will not be worn away and the picture will be kept for a long time. It has an effect that it is kept in a beautiful state over the entire area and the pattern is not easily visible.
