Description

Detailed Description of the Invention The present invention is a pachinko machine in which a pair of movable blades are pivotally supported on the front surface of a mounting plate so that they can freely stand up and tilt, and are operated in a state where it is easy for a ball to enter and a state where it is difficult to enter the ball. This invention relates to a winning ball device for a pachinko machine, and in particular, to a winning ball device for a pachinko machine that uses a new structure to cause the movable wing pieces to rise and tilt, thereby simplifying the overall structure and improving the efficiency of assembly work. It is.

Conventionally, many prize winning ball devices of this type have already been proposed and known. However, with such conventional devices, a pair of movable wing pieces are pivotally supported on the front side of the mounting plate, a chucker is attached below them, a guide box is attached to the back side of the mounting plate, and a side plate is attached to the guide box. An operating member for controlling the upright and tilting of the movable blade is supported on the shaft. In other words, in the conventional device, it is necessary to install a guide box on the back of the mounting plate and assemble operating members with a complicated shape inside it, which not only makes the assembly process complicated and time-consuming, but also makes the whole device large. The manufacturing cost was high. In addition, when attaching these to the game board surface, it is necessary to drill a large mounting hole for inserting the guide box, so if multiple pieces are installed, the game board will be weakened by the mounting holes, causing warping and distortion. There were disadvantages such as causing

In view of the above, the present invention has developed a new structure that eliminates the need for a guide box on the back side of the mounting plate by assembling parts for controlling the upright and tilting of the movable blades inside the chuck car that is mounted on the front side of the mounting plate. One object of the present invention is to provide a device which eliminates all the drawbacks of the conventional device described above.

Another object of the present invention is to provide an interesting prize winning ball device with a simple structure and at low cost, which can repeat the tilting state of the movable wing piece continuously or several times.

An example of implementing the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a mounting plate that is attached to the surface of the game board, and a through hole 2 is bored in the lower part of the center part. Reference numeral 3 denotes a chucker attached to the front surface of the mounting plate 1, the bottom of which communicates with the lower edge of the through hole 2, and the inner surface of the front wall 4 has two chucks at both upper sides and a lower position slightly closer to one side than the center. Shafts 5, 5 and 6 are provided protrudingly on the respective sides. Reference numerals 7 and 7' denote a pair of movable blades pivotally mounted on the shafts 5 and 5;

Reference numeral 8 denotes a rotating body located inside the chucker 3 and rotatably supported by a shaft 6. A plurality of balls (four in this embodiment) are arranged radially at approximately equal intervals from the central shaft cylinder 9. Receiving pieces 10a, 10b,
10c, 10d are formed, and a predetermined one ball receiving piece 10 among these plurality of ball receiving pieces 10a to 10d
A locking piece 11 that projects rearward is integrally provided at the rear end of the a. Then, one of the plurality of ball receiving pieces 10a to 10d of the rotating body 8 faces the passage path of the winning ball to the movable wing pieces 7, 7', and is divided into the ball receiving pieces 10a to 10d by the ball. It is installed so that it can be rotated by a certain rotation angle. 20
is a braking spring attached to the shaft 6, which presses the rotating body 8 against the inner surface of the front wall 4 of the chuck car 3 to produce a braking action and stop the rotating body 8 at a constant rotation angle. It is something.

One of the pair of movable wing pieces 7, 7' has a first engaging arm piece 12 projecting downward from the lower end of the rear edge at a predetermined inclination angle;
A second engaging arm piece 13 is integrally provided which projects inwardly at a predetermined angle from the center portion of the front edge. When the first engagement arm piece 12 engages with the locking piece part 11 of the rotating body 8, it holds one movable wing piece 7 upright, and the second engagement arm piece 13 holds the other movable wing piece 7. The other movable wing piece 7' is held upright by contacting the abutting portion 14 formed at the lower part of the inner surface of the wing member 7'. Note that one movable wing 7 is held in a tilted position with the tip of the first engagement arm 12 in contact with the shaft portion 5' of the other movable wing 7', and the other movable wing 7' is held in a tilted position. The chucker 3 is held in the tilted position by abutting its outer step against a retaining pin 15 protruding from the inner surface of the front wall 4 of the chucker 3.

Serial numbers 16a to 16d from 0 to 3 are displayed near the outer periphery of the surface of the circular plate 8' of the rotating body 8, corresponding to the number of ball receiving pieces 10a to 10d, and
The front wall 4 of the chuck car 3 has the numbers 16a to 1
A display window 17 corresponding to one of the numbers 6d is provided, and numbers 16a to 1 corresponding to the rotation angle of the rotating body 8 are displayed.
6d can be seen through the display window 17. Reference numeral 18 indicates a guide frame that guides the balls that have fallen onto the ball receiving pieces 10a to 10d of the rotating body 8 to the through hole 2, and 19 indicates the through hole 2.
This is a passageway frame that guides the balls flowing out from the game board to the winning path behind the game board.

The present invention has the above configuration, and its operation will be explained next. As shown in FIG. 5, when the first engaging arm piece 12 bored at the lower end of one of the movable wing pieces 7 is locked to the locking piece part 11 of the ball receiving piece 10a of the rotating body 8, , this one movable wing 7 stands up, and at the same time the other movable wing 7' also moves its abutting portion 14.
The second engaging arm piece 13 of one movable wing piece 7 is in contact with and held upright. Incidentally, at this time, the display window 17 of the chucker 3 corresponds to the number 16a of "0". In this state, the first ball B is moved to the movable wing pieces 7, 7'
When the ball falls between the balls, it falls onto the ball receiving piece 10a of the rotating body 8, and the weight of the ball causes the rotating body 8 to rotate.
As the rotating body 8 rotates, the first engagement arm 12 of one movable wing 7 disengages from the locking portion 11 and tilts under its own weight to open, and at the same time the other movable wing 7' also opens. The second engaging arm piece 13 separates from the abutting part 14, is released from its restraint, and tilts under its own weight to be in the expanded state as shown in FIG. When the next ball receiving piece 10b is positioned in the ball passing path between the movable blades 7 and 7' due to the rotation of the rotating body 8, the ball B falls to the bottom of the chucker 3 and passes through the through hole 2 to the passage frame 19. The ball flows out and becomes the winning ball. In addition, the display window 1 of the chat car 3
The number 16b of "3" corresponds to 7.

Next, in the expanded state shown in Figure 6, the second ball
When B' enters between the movable blades 7 and 7', it falls onto the ball receiving piece 10b of the rotating body 8 while raising the movable blades 7 and 7', and rotates the rotating body 8 with its ball weight. Then, the next ball receiving piece 10c is positioned on the ball passage path between the movable wing pieces 7 and 7'. At this time, since the ball receiving piece 10b of the rotating body 8 does not have the locking piece portion 11, both movable wing pieces 7, 7' are not held upright but are tilted again by their own weight to maintain the expanded state. At this time, the number 16c of "2" is displayed on the display window 17 of the chatter 3.
will be dealt with.

In addition, in this state, the third ball B' is moved to the movable blade 7,
7', this is the ball receiving piece 10c of the rotating body 8.
The weight of the ball rotates the rotating body 8 to position the next ball receiving piece 10d in the ball passage path between the movable wing pieces 7 and 7'. At this time, since the ball receiving piece 10d does not have the locking piece portion 11, the movable wing pieces 7, 7', which were once erected by the ball B', are tilted again by their own weight to maintain the expanded state. Further, the display window 17 of the chaser 3 corresponds to the number 16d.

In this state, the fourth ball B' moves to the movable blade 7,
7', and while standing it up, it falls onto the ball receiving piece 10d of the rotating body 8 and rotates, and the rotating body 8
The ball receiving piece 10a returns to the position shown in FIG. 5 after one rotation. Therefore, one of the movable wing pieces 7 is held upright with its first locking arm piece 12 being locked with the locking piece part 11 of the ball receiving piece 10a, and the other movable blade piece 7' is also held in the second position.
It is held upright by the locking arm piece 13. Then, the display window 17 of the chucker 3 again corresponds to the number "0" 16a.

In this way, the ball inserted between the movable wing pieces 7 and 7' rotates the rotating body 8 by a constant rotation angle divided by the ball receiver pieces 10a to 10d, and the ball receiver piece 1
Only when the ball receiving piece 10a on which the locking piece part 11 is provided among 0a to 10d is located in the ball passage path between the movable blades 7 and 7', the movable blades 7 and 7' are placed in the upright state. Since it is for holding, the movable wing piece 7,
The tilting state of 7' can be continued to give an advantage to the player. If, as in this embodiment, the number of consecutive tilting states is correctly displayed on the display window 17 of the chuck car 3 in relation to the rotation of the rotating body 8 to inform the player, the interest of the game will be increased. useful for. In addition, by providing the locking pieces 11 at two locations, for example, the ball holder pieces 10a and 10c, the movable wing pieces 7, 7' can be made to alternately stand up and tilt. Pieces 10a-1
Various changes are possible, such as increasing the number of 0d to allow more consecutive tilting states.

As described above, the prize winning ball device according to the present invention has the rotating body 8 that controls the upright and tilting of the movable wing pieces 7, 7' inside the chuck car 3 attached to the front surface of the mounting plate 1, so it is different from the conventional one. There is no need to provide a ball guide box on the back side of the mounting plate as in the case of the device, and the overall structure can be made smaller, and the assembly work is simple and can be manufactured at low cost. In addition, since there is no need to drill a large mounting hole to insert the ball guide box into the game board, it can be easily installed in locations that were previously considered difficult, and the installation process is simple and quick. There are effects that can be achieved.

Furthermore, we can provide a winning ball device that has a simple structure and can continuously repeat the tilting state of a pair of movable wing pieces several times, and also can easily display the number of tilting states. It is possible to provide a winning ball device having a structure.
