BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention receives a ball hitting a game area of a game board and performs its closed state by the action of an electric drive source, and the open state thereof does not act on the electric drive source. The present invention relates to a variable winning ball device of a ball game machine provided with an opening / closing plate which is carried out by its own weight under a state.

[0002]

2. Description of the Related Art Conventionally, a ball hitting a game area of a game board is received and the closed state is performed by the action of an electric drive source, and the open state is weighted under the non-acting state of the electric drive source. In the variable winning ball device provided with the opening / closing plate according to, the lower ends of the opening / closing plate are supported by the support shafts.

[0003]

Therefore, for the stability of the opening / closing operation of the opening / closing plate, it is necessary to maintain a good supporting state on the support shaft, but the opening / closing plate collides with a hitting ball dropping vigorously. Therefore, there is a problem in that the supporting state of the support shaft deteriorates due to long-term use, and therefore the opening / closing plate does not perform the opening operation due to its own weight even when the electric drive source is in a non-operating state. The present invention has been made in view of the above problems, and an object thereof is to provide a variable winning ball device for a ball game machine in which the opening operation of the opening / closing plate is reliably performed even after long-term use. Especially.

[0004]

In order to achieve the above-mentioned object, in the present invention, a ball hitting a game area of a game board is received and the closed state is performed by the action of an electric drive source. In a variable winning ball device of a ball game machine provided with an opening / closing plate for performing the open state by its own weight under the non-operating state of the electric driving source, the opening / closing plate is in the operating state of the electric driving source. It is characterized in that it has a contact portion to be in contact with, and a pressing portion to be pressed in the initial stage of the transition of the electric drive source from the operating state to the non-operating state.

[0005]

The opening / closing plate is provided with a contact portion that abuts in the operating state of the electric drive source and a pressing portion that presses in the initial stage of the transition from the operating state of the electric drive source to the non-operating state. Since it is provided, even if the support of the support shaft of the opening and closing plate deteriorates due to long-term use and the opening and closing plate does not rotate in the opening direction by its own weight, Since the pressing portion is forcibly pressed in the opening direction during the transition, the opening / closing plate is surely opened.

It is covered with glass plates 26a and 26b (see FIG. 1).

Next, a detailed structure of the variable winning ball device 50, which constitutes a main part of the present embodiment, will be described with reference to FIGS. 1 is a cross-sectional view showing the relationship between the opening / closing plate 53 and the solenoid 61, FIG. 2 is a perspective view showing the relationship between the opening / closing plate 53 and the solenoid 61, and FIG. FIG. 4 is a cross-sectional view, FIG. 4 is a perspective view of the main part of the variable winning ball device 50 as seen from the front, and FIG.
It is a front view of the variable winning ball device 50. In the figure, a variable winning ball device 50 has a mounting board 51 mounted on the surface of the game board 1, a rectangular winning opening 52 is formed in the center of the mounting board 51, and the winning opening 52 is closed. The opening / closing plate 53 is provided so that a winning space 54 is formed behind the winning opening 52.

Here, the structure of the opening / closing plate 53 will be described. The opening / closing plate 53 is formed by a rectangular flat plate, and support shafts 55a and 55b projecting from the lower ends of both ends are formed behind the winning opening 52. Bearing hole (not shown)
The upper side is opened by fitting with. Further, on the front surface of the opening / closing plate 53, side guides 56a and 56b are provided on both sides thereof, and a distribution protrusion 57 is provided on the center thereof. Side guides 56a, 56b
The distribution projection 57 guides the falling direction of the hitting ball that falls on the front surface of the opening / closing plate 53 in the closed state, and guides the winning opening 52 when the opening / closing plate 53 is opened. The opening / closing plate 5 is brought into contact with the surface of the lower mounting substrate 51.
It supports the impact of the hitting ball that collides with the No. 3 together with the support shafts 55a and 55b. Further, on the back surface of the opening / closing plate 53, rail projecting pieces 58, 59 that smoothly guide the hit balls received by the opening / closing plate 53 to the winning space 54 are provided. The rail projecting pieces 58 and 59 are formed such that the central rail projecting piece 59 is lower than the left and right rail projecting pieces 58.
The ball is received in the center of 3 and is guided to the rear as it is, so that the player is expected to be guided to either the specific first guide slope 72 or the normal first guide slope 74 described later. It is designed to give.

Further, as shown in FIG. 2, engaging portions 60 are formed at the rear portions of both ends of the opening / closing plate 53, and one engaging portion 60 is formed.
An engagement piece 64 fixed to the plunger 62 of the solenoid 61 via an actuating member 63 is engaged. The solenoid 61 is separated from the main body of the variable winning ball device 50 and is fixed to the solenoid mounting portion 25 of the lower cover body 22 as described above. Then, in order to stabilize the vertical movement of the plunger 62 of the solenoid 61, the operating member 6 directly fixed to the plunger 62.
The guide piece 65 is extended from the side of the guide member 3, and the tip of the guide piece 65 is slid along the groove of the guide member 66 fixed to the lower cover body 22. In the solenoid 61 in this embodiment, the winding coil is once connected to the board 67 (printed wiring board), and the board 67 is
The solenoid wiring 68 is soldered to the. With such a structure, compared to the conventional solenoid in which the tip of the winding coil is directly connected to the solenoid wiring as in the related art, the length of the winding coil at the time of manufacturing the solenoid is constant and the manufacturing is easier and the solenoid is easier to manufacture. Since it suffices to connect the wiring having the required length, the manufacturing cost can be reduced.

As is apparent from the above structure, the opening / closing plate 53 is opened / closed by turning on / off the solenoid 61. The opening / closing operation will be described in more detail with reference to FIG. First, the solenoid 61 is turned off
1A, the plunger 62 of the solenoid 61 is pressed downward by the urging force of the spring 62a around the solenoid 62, which causes the plunger 62 to be fixed to the plunger 62. The tip of the engaging piece 64 of 63 abuts against the abutting portion 60a that constitutes one of the protruding pieces of the engaging portion 60 to bring the open / close plate 53 into a standing state.

On the other hand, when the solenoid 61 is turned on, as shown in FIG.
Since the plunger 62 rises against the biasing force of the spring 62a, the tip end of the engaging piece 64 separates from the contact portion 60a and becomes inoperative. Due to this inactive state, the opening / closing plate 5
3 rotates in the opening direction about the support shafts 55a and 55b due to its own weight, but this is when it has not been used for a long time, and when it has been used for a long time, the support shafts 55a and 55b.
May be damaged or worn and may not rotate smoothly by its own weight. However, in the present embodiment, when the plunger 62 rises, the pressing portion 60b forming the other protruding piece of the engaging portion 60 is forcibly pressed by the engaging piece 64, so that the opening / closing plate 53 is opened in the initial stage. And the tilted opening / closing plate 5 while forcibly assisting rotation in the direction
3 is then completely opened by its own weight (Fig. 1
(State of broken line in (B)). The pressing range of the pressing portion 60b by the engaging piece 64 is such that, when the plunger 62 is most raised, the distance L between the tip of the opening / closing plate 53 and the inner glass plate 26b is substantially the same as the diameter of the pachinko ball P1. A little larger is desirable. This is because if the pressing portion 60b is pressed by the solenoid 61 to an interval smaller than the diameter of the pachinko ball P1, there is a disadvantage that a hitting ball falling between the opening / closing plate 53 and the glass plate 26b is bitten. .
Therefore, in this embodiment, it is possible to surely shift to the open state without biting the hitting ball when the opening / closing plate 53 is opened.

When the solenoid 61 is switched from ON to OFF, the plunger 62 descends, and the urging force of the spring 62 causes the engaging piece 64 to act on the contact portion 60a again to return the open / close plate 53 to the upright state. The side guides 56a and 56b and the distribution protrusion 57 have an opening / closing plate 5 attached thereto.
In order to increase the weight of the opening 3 in the opening direction, a weight may be embedded inside.

In the above-described embodiment, since the opening / closing plate 53 and the solenoid 61 are provided separately, the solenoid 61 is attached so that the relative positions of the solenoid 61 and the opening / closing plate 53 are accurate. There must be.
Therefore, in this embodiment, in order to accurately position the relative positions of the main body side of the variable winning ball device 50 provided with the opening / closing plate 53 and the lower cover body 22 to which the solenoid 61 is fixed, the lower cover body is provided. The positioning protrusions 24a and 24b projecting from 22 are engaged with positioning holes 92a and 92b, which will be described later, formed on the back surface side of the variable winning ball apparatus 50.

As shown in FIG. 3, a specific winning area 70 is formed at one end of the winning space 54, and a normal winning area 71 is formed at the other end opposite to the specific winning area 70. Are formed. The bottom surface of the winning space 54 is highest at almost the center thereof, and the first guide ramp 7 is inclined downward from the center toward the left and right ends.
2, 74, which is the specific winning area 70 and the normal winning area 71.
The second guide ramp 7 that slopes backwards just before
It is 3, 75. Then, in the normal winning area 71, the winning ball detector 78 faces immediately after, but further on the downstream side of the specific winning area 70, a backward guiding slope 76 is formed, and the backward guiding slope thereof is formed. A specific winning ball detector 77 is provided at the end of the path 76. In the illustrated case, since the rear guiding slope 76 is formed behind the rear wall 79 of the winning space 54, the winning ball detector 78 and the specific winning ball detector 77 are arranged side by side in the left-right direction. . In addition, the specific winning ball detector 77 is for detecting the occurrence of the continuation right described above, and cooperates with the winning ball detector 78 to receive the opening / closing plate 53 during one opening in the specific gaming state. It is for counting the number of winning prize balls.

The hit balls received by the opening / closing plate 53 and received in the winning space 54 roll on the first specific guiding slope 72 for specification and the second guiding slope 73 for specification, and the specific winning area 70. Or is guided to the normal winning area 71 by rolling the normal first inclined guide path 74 and the normal second guide inclined path 75. And
In this case, if the batting ball rolls to the right as viewed from the front, the batting ball is surely guided to the specific winning area 70, and if the batting ball rolls to the left as viewed from the front, the batting ball is Since it is surely guided to the normal winning area 71, it is possible to very easily determine which winning area 70, 71 the hitting ball is led to from the player.

In the illustrated embodiment, the rear wall 79 divides the winning chamber into a guiding chamber for guiding the winning balls and a processing chamber for processing the winning balls, and the specific winning ball detector 77 and the winning ball detector are disposed on the processing chamber side. Since it has a structure in which 78 is installed side by side, in the conventional variable winning ball device in which the center is the specific winning area and the left and right are the normal winning areas, the detector is installed in each of the sections Therefore, the number of detectors can be reduced, and the structure is simple as compared with a structure in which after the ball has passed through the specific winning area, the ball is joined to the passage in which the ball from the normal winning area is guided. Further, in the present embodiment, the hitting ball is the first guide slope 72 for identification and the second guide slope 73 for identification.
Since it takes a long time to roll over to reach the specific winning ball detector 77, the last winning ball of the number of winning balls allowed while the opening / closing plate 53 is opened rolls toward the specific winning area 70. If there is, there is a possibility that several extra hit balls will be received by the opening / closing plate 53 and become winning balls.

The structure of the main part of the variable winning ball device 50 is generally as described above, but the variable winning ball device 50 in this embodiment further has the following structure. That is,
On the left and right sides of the mounting board 51, the normal winning holes 80a, 8a

b, 18, 115 are driven to light, and the solenoids 12, 61 are driven via the solenoid drive circuit 109. In addition, the big hit information signal is led to the outside via the big hit information output circuit 110. In addition, the above devices and circuits include
Electric power having various voltages is supplied from the power supply circuit 111.

Although the variable winning ball device 50 according to the embodiment has been described above, the variable winning ball device 50 according to the embodiment contacts the opening / closing plate 53 when the solenoid 61 is in the operating state (OFF state). Since the contact portion 60a to be operated and the pressing portion 60b that presses in the initial stage of the transition of the solenoid 61 from the operating state to the non-operating state (ON state) are provided, the opening / closing plate 53 can be used for a long period of time. Spindle 5
Even if the support state of 5a and 55b deteriorates and the opening / closing plate 53 does not rotate in the opening direction due to its own weight, the pressing portion 60b is forced in the opening direction during the transition from the operating state of the solenoid 61 to the non-operating state. Since it is pressed, the open / close plate 53 is reliably opened. Also, the pressing portion 60b by the solenoid 61
Since the pressing range of is only in the initial stage, the problem of ball biting does not occur between the opening / closing plate 53 and the glass plate 26b.

In the above-described embodiment, the variable winning ball apparatus 50 is shown to have the inside divided into the specific winning area 70 and the normal winning area 71, but the inside is not divided or more than that. Although it may be divided or provided with a prize-ball detector 78 for counting the number of prize-balls received during one opening, it may be one without.

As is apparent from the above description, according to the present invention, the opening / closing plate is in contact with the contact portion in the operating state of the electric drive source and the operating state of the electric drive source. Since the pressing part that presses in the initial stage of the transition from the non-operating state to the non-operating state is provided, the support state of the support shaft of the opening and closing plate deteriorates due to long-term use, and the opening and closing plate rotates in the opening direction due to its own weight. Even without doing so, the pressing portion is forcibly pressed in the opening direction during the transition from the operating state to the non-operating state of the electric drive source, so that the opening / closing plate is reliably opened.
