Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a winning ball device in a pachinko game machine, and particularly to a so-called variable winning ball device in which the difficulty level of landing a pachinko ball in a winning area changes.

[Prior Art] As a winning ball device that is placed on the game board of a pachinko game machine and in which the difficulty level of winning a pachinko ball changes, a Yakumono ball device called a chulip is well known. ing.

[Problems to be Solved by the Invention] However, the above-mentioned Yakumono had the disadvantage that there was little variation in the difficulty level of winning prizes, that it could not fully meet the demands of players, and that it lacked the ability to make the game more interesting. .

Therefore, an object of the present invention is to provide a novel winning ball device in which the winning area is divided into winning areas having different values, and the value given to the pachinko ball differs depending on the winning location of the ball. be.

[Means for solving the problem] The present invention divides a winning area formed on a mounting plate attached to a game board into a plurality of sections, and makes at least one of the winning areas a specific area, and , a winning ball device having an opening/closing member that is driven by a driving means to open and close the winning area; This is a winning ball device in a pachinko game machine configured to be able to give a predetermined value depending on the presence of pachinko balls that have passed through an area.

[Operation] When the winning ball device enters a specific gaming state,
The opening/closing member opens the winning area by being driven by the driving means. If a pachinko ball lands in a specific area of the winning areas during the period when the winning areas are open,
A predetermined relatively large value is assigned. Conversely, if a pachinko ball enters a winning area other than the specific area during the period when the opening/closing member opens the winning area, a predetermined relatively small value is given.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1A and FIG. 1B are illustrative views of a variable winning ball device 30 according to an embodiment of the present invention. especially,
FIG. 1A is a perspective view thereof, and FIG. 1B is a longitudinal cross-sectional view of a specific area 32a defined so that the variable winning ball device 30 can be repeatedly opened and closed by the passage of balls.

Next, with reference to FIG. 1A, the variable winning ball device 3
The specific configuration of 0 will be explained.

A through hole is formed in the center of the decorative frame 31, which becomes a winning area 32 in which a ball can be won. On the front side of this through hole, an opening/closing plate 33 is provided so as to be freely openable on the front side. The lower side of the opening/closing plate 33 is supported by a shaft 332, and a U-shaped protrusion 331 is formed on the back surface of one side (the right side in the figure). This protrusion 331 is provided with a through hole. A pin 341 fixed to the tip of the lever 34 is inserted into the through hole. The other end of the lever 34 is supported by a fulcrum 342. An opening/closing mechanism 35, which is an example of a driving means for driving the opening/closing plate 33 to open or close, is provided above the lever 34. The opening/closing mechanism 35 includes a solenoid 351 , one end of a rod 353 is connected to a plunger 352 of the solenoid 351 , and the other end of the rod 353 is connected to a central portion of the lever 34 .

The winning area 32 includes a plurality of areas 32a, 32b,
It is divided into 32c. Among these, the balls that have won into the winning areas 32b and 32c are guided to the back side as they are (without driving any member of the variable winning ball device 30). Then, the balls flow out into a predetermined path of the pachinko game machine to which this variable winning ball device 30 is attached.

On the other hand, the winning area 32a formed in the center of the winning area 32 is a specific area defined so that the opening/closing plate 33 of the variable winning ball device 30 can be repeatedly opened and closed in accordance with the passage of balls. That is, the special prize area 32a is an area that can be given a predetermined value by being able to repeatedly open and close the opening/closing plate 33 of the variable winning ball device 30. Note that the configuration and operation for this will be explained in detail later.

Safe holes 36a and 36b are formed in the decorative frame 31 on both sides sandwiching the winning area 32. These safe holes 36a, 36b are formed to protrude to the front side from the surface of the decorative frame 31 so that they can always receive pachinko balls falling from above along the game board.

Next, the operation of the variable winning ball device 30 of this embodiment will be briefly explained. The opening/closing plate 33 is the solenoid 3
When the plunger 51 is energized and the plunger 352 is pulled up, it is opened as shown in FIG. 1A, and the winning area 32 is placed in an open state. On the contrary, solenoid 3
When the plunger 51 is deenergized, the plunger 352 is pushed downward by the force of the return spring.
The lever 34 rotates downward, closing the opening/closing plate 33 and closing the winning area 32.

Next, details of the specific area 32a will be explained with reference to FIG. 1B.

As mentioned above, the specific area 32a is the opening/closing plate 33.
This winning area is designed to accept a ball when the opening/closing plate 33 is opened to the front side, and to open the opening/closing plate 33 again if a hit ball wins while the opening/closing plate 33 is open. Therefore, it is necessary to detect the winning ball in this specific area 32a by some kind of detection means. Generally known means for detecting pachinko balls include a microswitch, a detector that detects magnetic flux density or capacitance that changes as the ball passes, or a photoelectric sensor.

On the other hand, there is a desire to use the playing area of the game board as effectively as possible, and in order to meet that request, the variable winning ball device 30 should be positioned as far down as possible on the game board (naturally, above the out ball entrance). It is desirable to have a configuration that can be installed in However, when the variable winning ball device 30 is installed below the game board, the installation location is too large for the above-mentioned known ball detection means, and it is impossible to install it spatially in relation to the out ball entrance. It had the disadvantage of becoming boring.

Therefore, in this embodiment, it was decided that the winning ball in the specific area 32a is detected by the detection means configured as follows.

That is, with reference to FIG. 1B, the specific area 32
At the bottom of the back surface of a is a path 3 that is inclined diagonally downward.
7 is formed. A ball detection member 38 is rotatably attached to the cutout portion of the path 37. The ball detection member 38 has two F-shaped pieces 38.
1,382, and the joint portion is supported by a shaft 383. and,
In the ball detection member 38, one side of the F-shaped member 381 is inserted into the path 37, as shown by the solid line in the drawing. In this state, when a pachinko ball enters the specific area 32a and passes through the path 37, the F-shaped member 381 is pressed counterclockwise. The pressed state is indicated by a dashed line.

A photocoupler 39 is provided at the upper position of the F-shaped piece 382 when the ball detection member 38 is pushed up most by the passage of pachinko balls. This photocoupler 39 includes a light emitting part and a light receiving part, and the amount of light received by the light receiving part differs depending on whether the F-shaped piece 382 is closest or not, and detects a passing ball based on the change in the amount of received light. It is something.

Note that the ball detection member 38 is made of a resin material, and has an F-shaped piece 382 facing the photocoupler 39.
In order to improve the reflection of light from the light emitting part, a reflective plate 384 is attached which is made of a glossy aluminum plate, aluminum paper, thin stainless steel plate, or thin iron plate that has been subjected to plating treatment.

In addition, as another member for detecting the passing ball, a reed switch is used instead of the photo coupler 39,
In addition, a so-called magnetic sensor using a permanent magnet in place of the reflecting plate 384 may also be used.
