Description

[Detailed description of the invention] [Industrial field of application] This invention is a combination pachinko machine that uses a ball receiving device, more specifically a ball, to play a game.
This invention relates to a ball receiving device used in a pinball game machine, such as a mahjong-style pachinko machine or a score-adding type pachinko machine, in which the game is played depending on the position of the ball dropping to the lower part of the board.

[Prior art] A conventional pinball game machine has a micro-switch arm protruding from a part corresponding to the position where the ball falls, and when the ball touches the arm of the micro-switch, it is possible to determine where the ball has fallen. The microswitch was used to detect whether this was the case.

In addition, a frame body, a plurality of passage holes formed side by side in this frame body, and a plurality of passage holes each located in each passage hole,
Those equipped with a plurality of levers individually pivoted on the frame (Japanese Patent Application Laid-Open No. 53-9651), those equipped with a rotating body (Japanese Utility Model Application Publication No. 16184-1984), and opto-sensors. There is one equipped with the following (Utility Model Application Publication No. 122181/1981).

[Problems to be solved by the invention] However, since the above-mentioned conventional detection device uses a micro switch, etc., this cannot be done when two balls enter the hole at the same position at the same time. was detected as one, causing problems with the game.

In order to prevent such detection errors, conventional systems have been designed to sort the fallen balls one by one and send the separated balls to the detection device, but this leads to an increase in the number of parts. It was becoming.

Further, due to the chattering that occurs in the microswitch, the detection part is likely to fail, and the overall lifespan of the microswitch is shortened.

Furthermore, in a device equipped with a plurality of levers individually pivoted to the frame (Japanese Patent Application Laid-open No. 53-9651),
Since the number of rotating shafts for each lever is required for the number of levers, the structure is complicated and the number of parts is large.

Therefore, the present invention was devised in view of the above-mentioned problems of the conventional technology, and its purpose is to solve the problem even if, for example, multiple balls fall into the socket in succession. It is an object of the present invention to provide a ball receiving device which not only can reliably detect all balls, but also has a simple structure and can reduce the number of parts.

In addition, a ball receiving device is used to ensure that all the winning balls can be detected even if a plurality of winning balls fall in succession.

[Means for Solving the Problems] The present invention is intended to achieve the above-mentioned objects, and the contents thereof will be explained below using embodiments shown in the drawings.

This invention protrudes from the front side of the board surface 60, and the board surface 60
A plurality of sockets 11 lined up side by side to catch balls flowing down, a plurality of passages 14 that individually guide the balls received by each socket 11 to the back side of the board surface 60, and a plurality of falls where the balls guided through each passage 14 fall individually. The opening 12 has an auxiliary receptacle 15 whose upper end communicates with a guide path (not shown) that guides winning balls (not shown) through the back side of the board 60 and whose lower end communicates with the drop opening 12. , board surface 60
A frame 10 fixed to the frame 10, a rotary shaft 30 passing through the frame 10 laterally and having both ends fixed to the frame 10, and rotatably fixed to the rotary shaft 30 individually. , a storage section 22 for receiving one ball falling through each drop port 12 and one ball falling through the auxiliary socket 15, and this storage section 22
A plurality of rotating bodies 20 each having a guide plate 23 that rotates the balls received by the rotating body by weight and guides the balls in the storage section 22 to each drop port 12 by this rotation, and a plurality of rotating bodies 20 that individually protrude from each rotating body 20. It is characterized by comprising a detection plate 25 and a plurality of opto-sensors 40 that individually detect the movement of each detection plate 25 and are fixed to the frame 10.

[Function] Therefore, according to the present invention, each rotating body 20 is serially passed through one common rotating shaft 30 at a position corresponding to each socket 11 of the frame 10, and the rotating bodies 20 are individually rotatably rotated. At the same time, an opto-sensor 40 is installed at a position corresponding to the detection plate 25 of each rotating body 20.
First, assemble the whole thing.

After that, when attaching the ball receiving device to the ball game machine, the plurality of receiving holes 11 of the frame 10 are inserted into the board surface 6.
The entire board is fixed as one piece from the back side of the board surface 60 so as to be located at the bottom of the front side.

After attaching it to the ball game machine in this way,
During the game, balls enter the socket 11 one after another. The balls that have entered each socket 11 are then placed in the storage section 22 of the rotating body 20.
Located in

When the ball is located in the storage section 22, a weight imbalance occurs in the rotating body 20, and the rotating body 20 rotates around the rotating shaft 30. The ball guided by the guide plate 23 falls into the drop opening 12.

Further, as the rotating body 20 rotates, the rotating body 2
Since the detection plate 25 protruding from the ball 0 also rotates at the same time, by detecting the rotation of the detection plate 25 with the opto-sensor 40, it is possible to easily detect the drop of the ball into the socket 11. .

Furthermore, according to the present invention, since the rotating body 20 is formed so that only one ball can fit into the storage section 22, after one ball enters the storage section 22,
Even if balls enter the same socket 11, the next ball will not enter the storage part 22 until the first ball that entered is dropped into the drop port 12.

Therefore, if two balls are placed in the same socket 11,
Even if it enters at an extremely short time interval,
The rotation of the rotating body 20 by the first ball completes the fall of the first ball into the drop port 12, and the next ball cannot be placed in the storage area unless the rotating body 20 returns to its current state. 22 will not be stored.

Therefore, according to the present invention, even if a plurality of balls fall into the same socket 11, the rotating body 20 rotates according to the number of balls, and this rotation determines whether or not the balls have passed. It is also possible to accurately detect passing balls, including the number of balls that have passed.

Also, if you win a prize with a prize (not shown) instead of through the socket 11, you will be guided to the back side of the board 60, and
Through the guide path (not shown) arranged on the back side,
The ball guided to the auxiliary socket 15 also passes through the auxiliary socket 15.
Similarly, when falling from the drop port 12, the rotating body 2
0 and is detected by the opto-sensor 40.

Therefore, according to the present invention, even if a plurality of balls win the same prize, the rotating body 20 rotates according to the number of balls, and this rotation determines whether or not the balls have passed. It is also possible to accurately detect passing balls, including the number of balls that have passed.

[Example] Figures 1 to 3 show an example of the present invention, in which Figure 1 is a partial perspective view showing an outline of a ball receiving device, Figure 2 is a perspective view of a rotating body, FIG. 3 each shows a cross-sectional view to show the operation of the rotating body.

In this embodiment, as shown in FIGS. 1 to 3, a frame 10 having a plurality of sockets 11 arranged side by side and a drop port 12 communicating with each socket 11, In addition, both ends are the frame body 10.
A plurality of rotating bodies 20 each rotatably fixed to a common rotating shaft 30 fixed to a common rotating shaft 30, a sensor board 41 having a plurality of opto-sensors 40 fixed thereon corresponding to each rotating body 20, and a sensor board 41. 41 to the frame 10.

As shown in FIGS. 1 and 3, the frame 10 includes an interior portion 13 for housing a large number of rotating bodies 20;
A socket 11 is provided that projects from the interior portion 13 to the front side of the board surface 60.

Further, as shown in FIGS. 1 and 3, the frame 10 is formed with a passage 14 for passing the ball along the way from the socket 11 to the drop opening 12.

At the lower part of the interior portion 13 in the direction of the socket 11,
As shown in FIG. 3, the drop port 12 is missing. The frame body 10 includes a socket 1 of the interior portion 13.
It is fixed to the board surface 60 from the back side of the board surface 60 so that the first side is in contact with the back side of the board surface 60. By being fixed to the board surface 60, only the socket 11 protrudes to the front side of the board surface 60.

In addition to the large number of sockets 11, as shown in FIG. 3, an auxiliary socket 15 is provided which does not protrude from the front side of the board 60 but has an opening only on the back side.

The auxiliary receptacle 15 is formed so as to guide the winning ball, such as an appropriate accessory provided on the board surface 60, to the auxiliary receptacle 15 via a guide path (not shown) on the back side of the board surface 60. An opto-sensor 4 installed in the auxiliary socket 15 indicates that a prize has been won.
This is for detection by 0.

The rotating body 20, as shown in FIGS. 2 and 3,
Its overall shape is approximately cylindrical with a shaft hole 21 in the center for pivotally supporting a rotation shaft 30 provided in the frame body 10. Further, a part of the outside of the circumference of the rotating body 20 is provided as a storage portion 22 which is large enough to accommodate approximately one ball. A guide plate 23 protrudes from the lower part of the storage section 22 for guiding the balls entering the storage section 22 to the drop opening 12.

Further, as shown in FIGS. 2 and 3, a weight 24 is fixed to the rotating body 20 on the side opposite to the housing section 22 when viewed from the shaft hole 21. Also, from the outer periphery approximately halfway between the weight 24 and the storage section 22, a detection plate 25 is located on the opposite side of the guide plate 23.
is installed protrudingly.

As shown in FIGS. 1 and 3, the sensor substrate 41 has a large number of opto-sensors 40 fixed to its lower surface.

As shown in FIG. 3, in each of the opto-sensors 40 described above, when the sensor board 41 is fixed to the frame 10 via the mounting material 50, the detection plate 25 of each rotary body 20 rotates as the rotary body 20 rotates. This detection plate 25 is arranged so as to cross the opto-sensor 40 when it rotates. When the detection plate 25 crosses the opto-sensor 40, the rotation of the rotating body 20 is detected by the opto-sensor 40.

Furthermore, each opto-sensor 40 is made up of a light emitter and a light receiver, and the light receiver detects light from the light emitter.

Next, the fixing of the ball receiving device having the above-described configuration to the board surface 60 and the actual operation thereof will be explained.

First, the assembly of the ball receiving device will be explained.

That is, a sensor board 41 on which a predetermined number of sensors 40 are fixed at a predetermined pitch, and a mounting material 5.
0. A frame 10, a rotating shaft 30 provided on the frame 10, and a predetermined number of rotating bodies 20 to be installed inside the interior portion 13 of the frame 10 are prepared.

Next, as shown in FIG. 3, the rotating bodies 20 are respectively positioned in the interior portion 13 of the frame 10, and the entire body is pivotally supported by one rotating shaft 30. At this time, the guide plate 23 of the rotating body 20 is in pressure contact with the lower surface of the passage 14 communicating with the socket 11 due to the uneven load of the weight 24.

That is, the rotating body 20 attempts to rotate so that the weight 24 moves downward when viewed from the shaft hole 21 . However, before the weight 24 reaches the lowest position, the guide plate 23 protruding from the rotating body 20 collides with the lower surface of the passage 14, so it stops at this position and waits.

In addition, in such a state, the detection plate 25 is connected to the opto-sensor 4 as shown in FIG.
Since the optical sensor 40 is far from the 0 position, the opto-sensor 40 is in a state where the light receiving body receives light from the light emitter.

Assume that at this time, the ball falls into the socket 11 of the frame 10.

The ball reaches the storage portion 22 of the rotating body 20 from the socket 11 through the passage 14. Then, the weight of the ball is added to the storage section 22.

Therefore, the entire rotating body 20 is rotated until the guide plate 23 collides with the edge of the drop port 12.

Such rotation of the rotor 20 causes the ball to fall through the guide plate 23 into the drop hole 12 .
At the same time, due to the rotation of the rotor 20, the detection plate 25 reaches the position of the sensor 40, and the light receiver is no longer able to receive the light from the light emitter.

Therefore, the stopping of light reception by the photoreceptor can be thought of in the same way as the falling of a ball, so the passing of a ball can be reliably detected.

Furthermore, even if two or more balls enter the socket 11 at the same time, the first ball enters the storage section 22 and the next ball does not enter the storage section 22 until it finishes falling.
I can't get into it.

In other words, since the ball cannot reach the drop opening 12, the ball receiving device always has one ball catch for each ball.
It will rotate.

Therefore, the number of balls that have entered the socket 11 can be reliably detected by the opto-sensor 40.

Also, if you win a prize with a prize (not shown) instead of through the socket 11, you will be guided to the back side of the board 60, and
Through the guide path (not shown) arranged on the back side,
The ball guided to the auxiliary socket 15 also passes through the auxiliary socket 15.
Similarly, when falling from the drop port 12, the rotating body 2
Detection plate 2 that rotates 0 and protrudes from the rotating body 20
5 crosses the opto-sensor 40, making the light receiving body unable to receive light from the light emitting body, making it possible to detect the passage of the sphere.

Therefore, the opto-sensor 40 can reliably detect the number of balls that have won prizes.

[Effects of the invention] As explained above, according to the invention, even if multiple balls fall into the receptacle in succession, not only can all the balls be reliably detected, but also all the balls can be detected. Even if a plurality of winning balls fall in succession, all the balls can be detected reliably, the structure is simple, and the number of parts can be reduced.
