00 and the solenoid 109 for actuating the decorative movable plates 110a and 110b are screwed to the back surface of the drive source mounting frame 96 via a mounting plate. Also, the solenoid 109
Is turned on when a specific game state is entered and a predetermined opening / closing cycle is started, and the above-described predetermined condition (until 9 opening / closing operations or 5 winning balls occur) is achieved. Alternatively, it is controlled to be turned off when a winning ball is won in the specific winning opening 63a before the predetermined condition is achieved.

In addition to the above-mentioned constituent elements, the above-mentioned back surface constituent plate 73 has the lens-shaped decorative plates 71a, 7a.
1b, lamp insertion holes 79a and 79b for mounting the decorative lamps 97a and 97b, and the opening / closing blade piece 53.
Rotating shaft insertion holes 79c and 79d (79d is not shown) through which the rotating shafts 66a and 66b of the a and 53b penetrate are provided, and a lamp and an electric drive source provided in the variable winning ball device 50 are further provided. Wiring of the winning ball passage cover pair 30
A relay board 116 for connecting to the control board via a relay board 44 provided on the board, and mounting bosses 78a, 78b (78a see FIG. 7) for fixing the board 116 are provided.

Further, in addition to the above-mentioned components, the drive source mounting frame 96 is provided with decorative lamps 97c to 97f for decorating the inside of the winning space 74 from the rear surface of the rear surface constituting plate 73, and further the opening / closing blades. Rotating shaft 6 of pieces 53a and 53b
Rear bearing tubes 99a, 99b into which 6a, 66b are inserted
(However, 99a is not shown). At the rear ends of the rear bearing sleeves 99a and 99b, the bearing member 69 is provided.
b and 69d are inserted. 1 in this embodiment
The two rotating shafts 66a or 66b are attached to the front and rear bearing tubes 68.
By bearing a, 99a or 68b, 99b, it is made different from the conventional bearing that is supported by a single long bearing tube extending in the front-rear direction. This has the disadvantage that the conventional long bearing cylinder is deformed due to heat change after molding or is deformed due to stress over a long period of time, which prevents normal rotation of the rotation shaft. On the other hand, by using the two relatively short bearing cylinders in the front and rear, it is possible to minimize the subsequent deformation and ensure a stable rotation operation of the rotation shaft for a long period of time. . Further, the drive source mounting frame 96 has opening / closing solenoids 120a, 1 (described later) for controlling the opening / closing operation of the opening / closing blades 53a, 53b.
Mounting bosses 117a to 117d for mounting the 20b are formed rearward.

Next, a mechanism for opening / closing the opening / closing blade pieces 53a, 53b will be described with reference to FIGS. "L" -shaped link members 131a and 131b (however, 131a is shown in FIG. 7) are fixed to the rear ends of the rotary shafts 66a and 66b of the opening / closing blades 53a and 53b.
Engagement pins 132a, 132 planted on 1a, 131b
b (however, 132a is shown in FIG. 7) is inserted and engaged in the engagement elongated holes 127a and 127b of the actuating member 125. The operating member 125 has a connecting pin 124 at the tip of the plungers 122a and 122b of the open / close solenoids 120a and 120b.
a and 124b (however, 124a is not shown) are connected. Then, the connected state is the operating member 12
5, the long holes 126a and 126b are bored, and the long holes 126a and 126b are formed.
Since the connecting pins 124a and 124b are loosely fitted in the a and 126b, the actuating member 125 is movable laterally and tiltable with respect to the plungers 122a and 122b within a certain range. It is connected in the state. Therefore, as shown in FIGS. 1 and 2, when the opening / closing solenoids 120a and 120b are fixed along a line L2 that is inclined at a slight angle with respect to the line L1 to which the original attachment should be made (in the illustrated embodiment, one opening / closing operation is performed). The solenoid 120a is normally fixed along the original line L1,
The other opening / closing solenoid 120b is fixed along the inclined line L2), but the plunger 122
b can be in a parallel state with the sliding empty portion 121b of the solenoid 120b, and when the solenoid 120b is excited, a specific portion of the plunger 122b is located at the solenoid 12b.
It does not come into contact with the 0b body to cause uneven wear. Further, as another embodiment of the coupling state of the plungers 122a, 122b and the actuating member 125, as shown in FIG.
26b instead of the notch holes 128a and 128b
25, the notch holes 128a and 128b may be loosely fitted to the forked ends of the plungers 122a and 122b and connected by the connecting pins 124a and 124b.
In addition, the structure is not limited to the above, and any structure may be used as long as the plunger and the actuating member are movable with respect to each other and can be tilted.

Further, the open / close solenoids 120a and 120b
Is firmly fixed by a screw 130 to a metal solenoid mounting plate 129 screwed to the mounting bosses 117a to 117d so that the mutual solenoids 120a and 120b do not vibrate due to the operation of the solenoids themselves.
The return spring 12 is attached to the plungers 122a and 122b.
3a and 123b are provided around the opening / closing solenoid 120.
When a and 120b are in the non-excited state, the urging force holds the actuating member 125 in the lowered position. In addition, an operating member dropout prevention piece 129a is bent in the lower center of the solenoid mounting plate 129. This is for facilitating the work when connecting the plungers 122a, 122b and the operating member 125. It has been formed.

Furthermore, the solenoid mounting plate 129 is
The opening and closing solenoid 120a is made of metal,
The opening / closing solenoids 120a and 120b are formed so as to be larger than the area to which the 120b is attached.
The heat generated during the operation of can be efficiently dissipated,
The attraction force of the plungers 122a and 122b is not weakened by heat, and the durability of the solenoid is improved. In this embodiment, the solenoid mounting plate 129 is used as the heat radiating plate, but the heat radiating plate may be attached to the solenoid separately from the solenoid mounting plate 129.

Then, as described above, the opening / closing solenoid 1
When the 20a and 120b are mounted on the solenoid mounting plate 129, the mounting holes for mounting the screws 130 are formed at slightly different positions due to design mistakes, or large mounting holes are formed. 1
Even if 20a and 120b are installed at an angle,
The open / close solenoids 120a, 120b operate normally to open / close the open / close blades 53a, 53b smoothly over a long period of time.

In this embodiment, the two plungers 1
Since one actuating member 125 is connected to 22a and 122b, the actuating member 125 always remains parallel to the solenoid mounting plate 129, and therefore the link member 112 is
The engagement state of the a and 112b with the engagement pins 113a and 113b can be reliably maintained. Therefore, conventionally,
It is not necessary to provide the restriction portion that is necessary to prevent the operating member from coming off the engagement pin of the link member.

In the illustrated embodiment, the two opening / closing solenoids 120a and 120b and one operating member 12 are used.
Although the case of connecting 5 and 5 has been described, one open / close solenoid and one operating member may be connected, or two open / close solenoids and two operating members may be connected respectively.

Next, referring to FIGS. 1 to 11, the operation of the embodiment will be described.
When the player operates 1 to start the game, the ball striking mechanism 20 drives a pachinko ball into the game area 8 of the game board 6, and the hit ball collides with an unillustrated obstacle nail or a windmill 14a to 14f. And flow down while changing the direction of the fall. Then, when the hit ball wins the start winning holes 11, 12a, 12b in the course of flowing down, the opening / closing solenoids 120a, 120b are given one or two pulse signals at relatively short time intervals. Along with this, the open / close blades 53a and 53b perform the opening / closing operation once or twice. The ball hitting the game area 8 during the opening or closing operation once or twice is the opening / closing wing pieces 53a, 5
When the player wins the prize by being guided to 3b and the prize ball wins the special winning opening 63a, the special game state is established. When the specific game state is reached, the specific game state notification lamps 15a, 15b,
The frame lamps 28a and 28b blink, and further, the decorative LED 58 and the decorative lamp 9 provided in the variable winning ball device 50.
7a to 97f are lit or blinking to notify the player that the specific game state has been reached. The decoration LED 58 and the decoration lamps 97a to 97f may be turned on or blinked for demonstration in a normal state to enhance the decoration effect.

On the other hand, in the specific game state, a drive signal is sent to the solenoid 109 and the sliding operation plate 105 is slid downward. As a result, the ball stoppers 101a and 101b, which are the second distributing member 100, are rotated so that the locking portions 102a and 102b of the ball stoppers 101a and 101b project to the front surface of the lower ball channel plate 76, and that state is maintained. (See FIGS. 6 and 7). In this situation,
A pulse drive signal with a relatively short time interval is again sent to the open / close solenoids 120a, 120b, and the open / close wing pieces 53a,
53b repeats opening and closing. These open / close wings 53a, 53b
The ball hit by the opening / closing blades 53a, 53b during the opening / closing operation of the above is guided on the ball rolling plate portion 81 of the first distributing member 80 and guided rearward, and then from the communication port 86 to the lower ball flow passage portion. 76
Is guided to one of the three passages partitioned by the partition plates 85a and 85b. The left and right passages of the three passages are closed by the locking portions 102a and 102b, so that the winning balls guided to the left and right passages are
It will be stored until the locked state is released.
Moreover, in the case of this embodiment, the winning balls flowing down on the ball rolling plate portion 81 fall from the left and right communication ports 86, so that there is a high possibility that they are preferentially stored in the above-mentioned left and right passages. However, since the number of coins to be stored is two each on the left and right, more prize balls overflow from the rear part of the partition plates 85a and 85b into the central passage and flow down the lower rolling plate 76a, and the specific prize hole 63a or General prize holes 63b, 63c
Be induced to either.

As described above, the open / close cycle of the open / close blades 53a, 53b has progressed to some extent, and the open / close operation has reached 9 times, or the number of winning balls counted by the 10-count detection switch 35 has reached 5. In this case, the drive signal of the solenoid 109 is stopped, the sliding operation plate 105 rises, the ball stoppers 101a and 101b rotate reversely by their own weight, and the locking state of the locking portions 102a and 102b is released, and the accumulation is completed. Cancel the accumulated prize balls. The released stored balls flow down on the lower rolling plate 76a, and are almost guided to the general winning openings 63b, 63c. At the same time, the rotation driving signal of the drive motor 92 is output, the first distributing member 80 starts to move up, and the ball rolling plate portion 81 of the first distributing member 80 moves to the highest position, that is, the drive motor 92. The rotation stops at the time when the half-turn has occurred (see FIGS. 8 and 9). In this state, the open / close blades 53a, 53
The winning balls guided by b are open / close blades 53a, 53
It directly drops from b and collides with the inclined plate 61, and the winning space 74
Is bounced off toward the rear and falls onto the lower rolling plate 76a, then flows down toward the front, and the specific winning opening 63a
Alternatively, the player can be guided to either the general winning opening 63b or 63c.

When the winning ball guided as described above is guided to the specific winning port 63a, the opening / closing blade pieces 53a, 5 are again provided.
3b repeats a predetermined opening / closing cycle. At this time, the rotation drive signal is again output to the drive motor 92, the distribution member 80 returns to the original state, and the drive signal is sent to the solenoid 109 to cause the locking portion 102a. , 102b protrude, and then the opening / closing cycle of the opening / closing blades 53a, 53b starts. Further, the maximum number of repetitions of the opening / closing cycle is determined to be eight, but if the number of repetitions of the opening / closing solenoids 120a and 120b becomes the maximum in the specific game state, one specific operation is performed. In the game state, the opening and closing solenoids 120a and 120b are operated hundreds of times to hundreds of times. Therefore, if the connection state of the opening and closing solenoids 120a and 120b and the operating member 125 is not accurate, the plungers 122a and 122b of the opening and closing solenoids 120a and 120b are used for a short period of time.
Due to uneven wear, the opening / closing operation of the opening / closing blades 53a, 53b may not be performed smoothly. However, in the case of this embodiment, since the coupling state of the plungers 122a, 122b and the actuating member 125 is movable and can be tilted, there is durability, and since two solenoids are used. , The load on each solenoid is small. Therefore, a long-term smooth opening / closing operation of the opening / closing blades 53a, 53b is guaranteed.

Further, in this embodiment, one rotary shaft 66a or 66b is connected to the front and rear two bearing cylinders 68a and 99a.
Alternatively, the bearings 68b and 99b are used to make the bearings different from the bearings which are conventionally supported by one bearing cylinder long in the front-rear direction. It has a drawback that it deforms due to heat change or deformation due to stress over a long period of time, which hinders the normal rotation operation of the rotation shaft. By doing so, it is possible to minimize the subsequent deformation and to ensure the stable rotation operation of the rotation shaft for a long period of time.

It is to be noted that, before the first distributing member 80 operates by an operation not described in the above operation, the specific winning opening 63a
When the winning ball is guided to the solenoid, the solenoid 109 is immediately de-energized, and the ball stoppers 101a, 10a
1b reversely rotates to release the locked state of the locking portions 102a and 102b, and after a predetermined time elapses, the solenoid 109 is excited again to operate to start the next opening / closing cycle. In addition, when a predetermined opening / closing cycle (18 opening / closing operations or occurrence of 10 winning balls) is achieved without the winning balls being guided to the specific winning opening 63a while the first distributing member 80 is operating. , The specific game state ends, but a rotation drive signal is sent to the drive motor 92 to return the first distributing member 80 to the original state.

In the above-described embodiment, the pair of open / close blades 53a and 53b are exemplified as the movable member, but the invention is not limited to this.
It may be a movable piece that slides in the lateral direction.
