Description

  The present invention relates to a variable winning device for a pachinko machine.

The variable prize device equipped in the pachinko machine has a rotary wing piece and a door that opens and closes at the prize opening, and opens and closes the rotary wing piece and the door according to changes in the winning conditions. On the other hand, it is possible to change the winning state by releasing a large number of prize balls by enabling a large number of winnings when opening.
The present invention includes a door that opens and closes at the prize opening in the variable prize winning device, receives a hit ball that falls when the door is opened at the door (actually the back of the door), and guides it to the prize opening. The present invention relates to a variable winning device of a type that can acquire a large number of winning balls.

This variable prize-winning device is generally referred to as a big prize opening or an attacker. When the door opens a ball that is equipped at the lower part of the game board and falls toward the out-going opening, it receives a lot of prizes. It can be a sphere.
Normally, this variable prize winning device has a ball gathering chamber that accepts a winning ball behind the winning opening, aligns the balls when a number of balls have won at the same time, and guides them to the Ryukyu outlet. Alignment guidance can be performed toward the guide path following the ball discharge port.

  In order to align the winning balls, the bottom plate in the ball assembly chamber is generally inclined, arranged in a horizontal row using the narrow depth space of the ball assembly chamber, and opened to the lower end of the inclination using the horizontal inclination. A method of guiding and aligning to a sphere discharge port is adopted.

However, when a large number of winning balls enter at the same time only by the inclination of the bottom plate, the so-called bridging phenomenon such as ball biting occurs in the vicinity of the ball discharge opening, which may cause clogging of the ball.
As one method for solving this problem, a collision wall for winning balls is formed opposite to the ball discharge port that opens at the lower end of the bottom plate that is inclined, and the ball discharge port is guided by the inclination of the bottom plate. A variable winning device has been proposed in which a winning ball that strikes against the collision wall and another subsequent winning ball is pressed against the collision wall and dropped into the ball discharge port with the resultant force to prevent the biting of the ball. For example, the invention disclosed in Patent Document 1 is an example.
Japanese Patent Publication No. 8-2385.

The invention described in the above-mentioned patent document 1 is configured so that a winning ball guided along the inclination of the bottom plate (winning ball guiding rod 10) of the ball collecting chamber (winning ball collecting space 3) is discharged from the outlet (winning ball outlet 15). A winning ball collision wall (18) for colliding and receiving on the opposite side is provided opposite to the upper surface of the bottom plate.
When the ball discharge port opens at one end of the ball gathering chamber as disclosed in Patent Document 1, the wall at this end becomes a winning ball collision wall, which can be substituted, but the ball discharge port is the ball gathering port. In the case of opening in the center of the chamber, it is necessary to form the winning ball collision wall (18) while standing from the bottom plate.

When this ball discharge port is located at the center of the ball gathering chamber, the bottom plates on the left and right are divided up and down to form the required step to form the winning ball collision wall (18).
However, it is necessary to increase the height of the ball gathering chamber in accordance with this, so that a step having a height sufficient for the winning ball to collide with the ball gathering chamber needs to be increased accordingly. The height of the device itself will increase and become larger.

Increasing the size of the above-mentioned device increases the limited installation space of the game board, which presses the installation space of other components and is not preferable in terms of board design.
However, it is difficult to guide the winning ball in one direction by always opening the ball outlet at either the left or right end of the ball gathering chamber due to the relationship with other winning ball guiding paths, and so on. There is often a need to open it to a different location and a solution is sought.

  The present invention has been developed to solve this problem in view of the above-described circumstances. In the variable winning device, a ball discharge port is opened without providing a collision wall or a step on the bottom plate in the central portion of the ball gathering chamber or in the vicinity thereof. It is another object of the present invention to provide a variable winning device for a pachinko machine that allows the winning ball to be released from the system without clogging the ball.

  In order to achieve the above-mentioned object, the present invention opens a ball discharge port for discharging a winning ball at or near the center of the rear wall that closes the rear part of the ball gathering chamber, and the bottom plate of the ball gathering chamber has the above-mentioned The front central plate part facing the ball discharge port is formed on the inclined surface after the downward slope toward the ball discharge port, and the left and right side plate parts sandwiching the central plate part are respectively separated from the left and right end portions to the central plate part. Along the inclined surface at the position where the winning ball that has entered the front entrance of the ball gathering chamber is formed with a downward slope toward the winning opening that opens to the front of the ball gathering chamber and that enters through the winning opening. In other words, it is guided to the ball discharge port while aligning the spheres until reaching the central plate portion.

  More specifically, the present invention includes a door that is opened and closed by an electric drive source at a winning opening that is opened on the mounting substrate, and receives a winning ball through the winning opening when the door is opened, In the variable prize winning device that is guided to discharge out of the system through a ball discharge port that opens toward the bottom plate of the ball collection chamber, the ball collection chamber is located between the mounting substrate and a rear wall that stands behind the prize collection port. A rear inclined surface that is formed in the rear wall and opens the spherical outlet facing the bottom plate in the central portion of the rear wall, while the central plate portion of the bottom plate in front of the spherical outlet is inclined downward toward the spherical outlet. And the left and right side plate portions of the bottom plate sandwiching the center plate portion are formed on front inclined surfaces that are downwardly inclined in both directions of the center plate portion and the winning opening, respectively. To provide a variable winning device

  The variable winning device according to the present invention configured as described above receives a winning ball that jumps into the ball gathering chamber through the winning opening for guidance on the door that is opened and protrudes in front of the winning opening, on any plate portion of the bottom plate, The center plate part is guided to the respective slopes, and finally guided to the ball discharge port so as to be sent to the winning ball guide path.

  In this guidance, when there are a large number of winning balls at the same time and a plurality of winning balls are received by the left and right side plate parts, if there is a difference in the speed to reach the central plate part, the first one will be given priority in order. When the ball reaches the center plate portion from the left and right at the same time, there is a risk of meshing at the front edge of the center plate portion, and there is a risk of clogging the ball.

  Conventionally, when a ball clogging occurs in this way, it is necessary to open the glass frame and remove the meshed winning ball, or to apply an impact and flow into the ball discharge port. The door that is opened is always closed as the predetermined time elapses or other conditions are set, and the winning opening is closed. The ball biting state is eliminated by utilizing the impact.

  The winning balls that are impacted by the door closing are pushed into the Ryukyu discharge port as they are, and the left and right side plates may be pushed back backwards. It rolls toward the door according to the inclination, and further toward the central plate portion at the center, and is guided to the ball discharge port, whereby the ball clogging state is completely eliminated.

  Therefore, according to the present invention, in the variable prize winning device, it is possible to open a ball outlet in the central part of the ball gathering chamber or in the vicinity thereof. As a result, the design of the variable prize-winning device can be made free, and there is no need to provide a step for eliminating the ball clogging on the bottom plate, so that the height of the entire device can be increased by raising the ball gathering chamber. As a result, a miniaturized variable prize-winning device can be manufactured, and unnecessary restrictions are not imposed on the design of the game board.

The drawings show an embodiment which is a specific example of the variable prize device according to the present invention described above.
In this embodiment, the present invention is applied to a large prize opening device provided with a first prize opening provided with doors that open and close up and down and a second prize opening, respectively. 1 is a front view of the apparatus, FIG. 2 is a plan view, FIG. 3 is a right side view, FIG. 4 is a front view of the first winning opening, FIG. 5 is a plan view of FIG. 6 shows a right side view in the state of FIG. 4, FIG. 7 shows a cross-sectional view taken along line AA in FIG. 4, and FIG. 8 shows a cross-sectional view taken along line BB in FIG.

In the drawings, 1 is a grand prize device according to the present invention, 2 is a mounting board for mounting the apparatus on a game board, 3 and 4 are horizontally long first winning openings opened on the mounting board vertically. , 2nd prize opening, 5 and 6 are doors which are pivotally attached to each prize opening freely.
The upper and lower winning holes 3 and 4 are formed by dividing the opening 7 opened in the mounting substrate 2 into two vertically. Here, it is divided by the installation of the door 5 that extends horizontally in the middle of the height of the opening 7.

  The door 5 is freely swingable back and forth by causing the bearings 8 and 8 provided in the middle of the right and left edges of the opening 7 to support pivot shafts (not shown) provided at both ends of the lower edge. It is configured to change between a closed posture that stands vertically and closes the first winning opening 3 and an open posture that tilts forward and receives the hit ball A.

  The door 6 provided in the second winning port 4 has a guide base 9 and 9 that projects from the front surface of the mounting substrate 1 and guides the hit ball A to the second winning port 4, and has a lower edge. Pivoting shafts (not shown) projecting at both ends of the door are supported by this, and the same as the door 5 is stood up to close the second winning opening 4 and tilted forward to enter the hit ball. It is designed to change to an open posture that allows

Reference numeral 10 in the figure denotes a frame formed on the back surface of the mounting substrate 2, and the first half of the frame corresponding to the first winning opening 3 is provided in the front half of the frame along the mounting substrate 2. 11 and a second ball gathering chamber 12 corresponding to the second winning opening 4 are provided side by side.
The two ball collecting chambers 11 and 12 are separated from a space 14 for a ball passage provided behind by a rear wall 13 that closes the back surface, and the diameter of the pachinko ball is set between the rear wall 13 and the mounting substrate 2. A depth exceeding the depth is provided so that the ball A can be received into the room.

  The ball gathering chambers 11 and 12 positioned above and below are substantially divided by a bottom plate 15 that forms the bottom of the upper first ball gathering chamber 11, and the leading edge of the bottom plate 15 is used as the opening of the winning opening 4. The wide opening 7 is also vertically divided into two at the same time by projecting under the pivoted end of the door 5.

The bottom plate 15 guides the winning balls A that enter the first ball gathering chamber 11 to the ball discharge port 16 while aligning them in a line, and from there to the ball guide path 17 and to face the guide path 17 in the middle. In order to guide to the detection switch 18, a rearward inclined surface that leads to the ball discharge port 16 is provided on the upper surface.
The ball discharge port 16 in this embodiment is opened at the left end of the rear wall 13 of the ball assembly chamber 11 as disclosed, and therefore the upper surface of the bottom plate 15 has a downward slope toward the rear side. Along with this, an inclined surface with a left slope that goes from the right to the left is attached.

  For this reason, when the door 5 falls forward with the support shaft as a fulcrum and the first winning opening 3 is opened, the door 5 falls to the door 5 and is guided by the inclination to jump into the winning opening 3. The winning balls are guided by the inclination of the bottom plate 15 in the ball gathering chamber 11 and once brought to the rear wall 13. Here, when a plurality of spheres enter at the same time, they are aligned by the wall 13, and then guided to the sphere discharge port 16 while being guided to the right-to-left inclination and to the sphere guide path 17. Will be guided.

On the other hand, the lower second ball gathering chamber 12 has a bottom plate 20 for guiding the incoming winning ball A to the ball discharge port 19.
The ball discharge port 19 has the space 14 provided behind the ball gathering chambers 11 and 12 in order to prevent the ball guiding passage 21 connected to the back from interfering with the ball guiding passage 17 following the first ball gathering chamber 11. Is formed in the central portion of the rear wall 13 along with the formation in the central portion. Therefore, an inclined surface for guiding the winning ball toward the ball discharge port 19 is formed on the upper surface of the bottom plate 20.

  FIG. 11 is a perspective view showing the upper surface of the bottom plate 20, which will be described together with FIGS. 7, 8, and 10. The upper surface of the bottom plate 20 is a central plate portion 20 a that contacts the front of the ball discharge port 19. Are formed on the rear inclined surface that is inclined downward toward the ball discharge port 19, and the left and right side plate portions 20b and 20c sandwiching the central plate portion 20a are inclined downward toward the center and simultaneously forward. It is formed in the front inclined surface which becomes a downward slope toward.

  The central plate portion 20a is formed to have a lateral width substantially equal to the diameter of the pachinko ball in order to guide the winning balls one by one to the ball discharge port 19, and the winning balls guided here follow a backward inclination. The ball is automatically guided and sent to the ball discharge port 19 opened in the rear rear wall 13.

On the other hand, the winning balls received by the left and right side plate portions 20b, 20c first roll forward, that is, in the direction of the winning opening 4 according to the forward and downward inclination, and the edge (door 6) of the door 6 opened here is opened. The lower end of the head).
When a plurality of balls are on the side plate portion 20b or 20c through this forward rolling, they are aligned side by side by contact with the edge of the door 6, and then the side plate portions 20b and 20c According to the inclination toward the center, rolling is induced to the central plate portion 20a. Then, the spheres guided to the central plate portion 2a are sent to the sphere discharge port 19 in order as described above.

  As the winning balls are sequentially guided in this way, the winning balls gathered from the left and right side plate portions 20b and 20c reach the central plate portion 20a at the same time, and the front edge of the plate portion 20a is in a ball-engaged state. Then, the subsequent movement stops, and the subsequent winning balls are stored in the Ryukyu gathering chamber 12 as they are. When a predetermined time elapses in this state, the door 6 is closed by a preset door closing command. Since it operates, the winning ball that closes on the door 6 and creates the above-mentioned ball-engaged state is subjected to an impact or swinging motion associated with the closing operation. As a result, the meshing balance is lost and the ball is automatically jammed. Will be eliminated.

  As is well known, the above-mentioned ball biting is generally caused by the sticking of spheres when the spheres move from a wide area formed for alignment to a narrow area like a supply bowl of spheres. Ball engagement in the gathering chamber is a small-scale bridging phenomenon that occurs when a small number of balls collide with each other in the middle of the flow, resulting in a balance of forces. , Will start the guidance again.

  The winning spheres whose ball bites are broken at the front edge of the central plate portion 20a enter the ball discharge port 19 one by one by making a normal flow, and a ball guide provided behind the second ball collecting chamber 12 The vehicle enters the path 21 and passes through the detection switch 22 that faces the ball guide path 21 and is sent to the winning ball path behind the game board.

  In the figure, reference numeral 23 is a solenoid as an electric drive source for opening and closing the door 5 for opening and closing the first winning opening 3, and 24 is a solenoid for opening and closing the door 6 for opening and closing the second winning opening 4. It is. Reference numeral 25 denotes an electric decoration board for blinking and decorating a lamp (not shown) provided on the mounting board 2, 26 is an electric decoration relay board, 27 supplies electric power to the solenoids 23 and 24, and It is a relay board that relays the detection signals of the detection switches 18 and 22.

In the large winning opening device 1 constructed as described above, the upper and lower doors 5 and 6 are normally closed so that a winning is impossible, and when the solenoid 23 is excited in response to an external signal, the first door 5 Open.
The door 5 is expected to receive a winning ball from directly above and from the left and right, and after being opened for a certain time, the door 5 is closed according to the game settings. During this time, the winning ball in the first ball gathering chamber 11 is guided to the bottom plate 14 and directed to the ball discharge port 16, thereby being sent to the winning ball passage through the ball guiding path 17.

On the other hand, when the solenoid 6 is excited to close the second winning opening 4 and the door 6 is opened, when the upper door 5 is in a closed state, the ball is dropped from directly above the guide stand. The balls 9 and 9 receive the hit balls from the left and right through the inwardly inclined upper surfaces, and pass them through the winning holes 4 as indicated by arrows by the inclination of the door, and are received by the second ball collecting chamber 12. It will be.
In the second ball gathering chamber 12, all the winning balls are collected in the central plate portion 20 a at the central portion by the upper surface of the bottom plate 20, and are then guided to the ball discharge port 19.

As described above, the winning ball A received by the left and right side plate portions 20b and 20c is first returned to the front winning port 4 side by the forward inclination, and the pivotal attachment of the door 6 facing the winning port 4 is performed. It will contact the edge on the end side. At this time, when there are a plurality of winning balls at the same time, they are aligned side by side by rolling forward.
After contact with the edge of the door 6, the door 6 is collected in the central plate portion 20a by using a downward gradient toward the inner side of the side plate portions 20b and 20c, that is, toward the central plate portion 20a. Then, it is guided to the ball discharge port 19. In the meantime, when the balls from the left and right side plate portions 20b and 20c collide with each other when the front edge of the central plate portion 20a is reached and the balls are engaged, this is eliminated by the closing operation of the door 6 as described above. As a result, ball clogging is prevented.

  Therefore, as is clear from the above description, according to the device of the present invention according to the above configuration, it is installed from the relationship with the first ball assembly chamber 11 installed above or directly above the grand prize opening device. When a ball discharge port is opened at either the left or right end of the ball gathering chamber due to the placement relationship of the winning ball guiding passage connected to the starting winning port (not shown) As described above, the ball biting which has become a problem when the ball outlet is unavoidably opened in the center can be reliably eliminated as described above. It is possible to set a special prize opening device, that is, a variable winning device.

  In the present invention, a step is provided on the upper surface of the bottom plate 20 that guides the winning ball toward the ball discharge port 19 in the central portion as in the conventional device in order to avoid the collision of the winning ball from the left and right directions. There is no need to increase the height of the ball gathering chamber, so there is no need to increase the overall height of the variable prize-winning device to expand the installation space in the game board, and there is no restriction on the installation space.
