Description

[Detailed description of the invention] <Industrial application field> The present invention forms a downstream direction guide part in at least one of the plurality of channels formed in the variable prize winning device, and the action of this downstream direction guide part is This invention relates to a pachinko machine in which winning balls are distributed to the upstream side of an inclined guide shelf of a winning ball collection gutter provided on the back side of a game board to flow out winning balls.

<Prior art> In a conventional pachinko machine, a wide winning ball collecting gutter is vertically provided on the back side of the game board, and one winning ball is placed at the lower end of an inclined guide shelf at the bottom of the winning ball collecting gutter.
A winning ball flow control device is installed to control the flow of individual winning balls, and the winning balls from each winning device flowing out to the back side of the game board are received by the inclined guide shelf of the above-mentioned winning ball collection gutter, and the winning balls are transferred to the inclined guide shelf. The winning balls are guided to the flow control device while lining up in a line.

<Problem that the invention aims to solve> However, in recent years, a variable winning device has been developed that can win a large number of balls in a very short period of time when a specific condition is achieved during a game. Pachinko machines with a winning device installed at the bottom of the gaming section are becoming increasingly popular. In such pachinko machines, when the variable winning device opens, a large amount of winning balls are temporarily generated, so the winning balls are concentrated in the winning ball flow down controller within a very short time, and these winning balls are It is easy to cause problems such as stacking up like a stone wall on the slanted guide shelf and getting stuck.

<Means for Solving the Problems> The present invention was proposed in view of the above, and includes a variable winning device with multiple channels through which winning balls flowing into the continuous inflow port and the general inflow port flow down to the winning ball collecting gutter. At least one of the plurality of channels is formed with a downstream guide portion for causing the winning balls to flow out toward the upstream side of the inclined guide shelf of the winning ball collection gutter.

<Function> Since the downstream direction guide part changes the downstream direction of the winning balls, the winning balls flowing down from the channel in which the downstream direction guide part is formed head toward the upstream side of the inclined guide shelf of the winning ball collection gutter. In this way, when the winning balls flowing down from the flow path of the variable winning device to the inclined guide shelf of the winning ball gathering gutter are dispersed, the time required for each winning ball to reach the winning ball flow down controller is different, so it is extremely Even if a large number of batted balls enter the variable winning device in a concentrated manner within a short period of time, these winning balls flow down the inclined guide shelf of the winning ball collection gutter in a dispersed state. Therefore, the rectification state on the inclined guide shelf of the winning ball collection gutter becomes smooth, and it is possible to eliminate lumps of winning balls especially near the entrance of the winning ball flow down controller.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

As shown in FIG. 1, the pachinko machine 1 has a ball feeding tray 3, a receiving tray 4, a ball firing operation section 5, etc. on the front side of a frame-shaped front frame 2, and the window section of the front frame 2 is closed from the back side. A game section 8 surrounded by a guide rail 7 is formed on the surface of the game board 6 installed in this manner, and within the game section 8 there are a general winning hole 9, a special winning hole 10..., a tulip type winning hole 12... and a variable winning hole. Winning devices such as a winning device 13 are arranged, and a display section 11 is arranged approximately at the center of the gaming section 8.

Therefore, when the player operates the batted ball firing operation unit 5, the batted ball firing device 14 can fire one ball in the ball supply tray 3, and the fired batted ball is sent to the game via the guide rail 7. The top of section 8 is reached. Then, the hit ball that reaches the top of the game section 8 flows down while hitting the obstacle nail, enters the above-mentioned winning hole or winning device, and flows out to the back side of the game board 6 to become a winning ball, or flows down as it is. The ball enters the out hole 15 and becomes an out ball.

As shown in FIG. 2 and subsequent figures, the variable winning device 13 has a ball inlet 17 in the approximate center of a board 16 attached to the surface of the game board 6, and the ball inlet 17 can receive a plurality of balls at once. It is formed horizontally so that it can be used. A door plate 18 is pivotally attached to the lower edge of the ball entrance 17 by shafts 19, 19 so as to be openable and closable. This door plate 18 is always on the outside (board 16
It is biased by its own weight, a weight, or a spring so as to open toward the front), and an engaging arm 20 is attached to one side edge of the back surface.

A surrounding frame 21 is provided on the back surface of the substrate 16 so as to surround the ball inlet 17, and a third
As shown in the figure, a continuous inlet 22 forming a continuous inlet 30 located approximately at the center of the ball inlet 17 and recessed downward, a pair of general inlets 31 located on the left and right,
31 and general guide ports 23, 23 are provided. A mountain-shaped branch portion 24 is formed between each side edge of the continuous guide port 22 and the side edge of each general guide port 23, 23. At the open rear end of the surrounding frame 21, the mounting board 25 and the back plate 26 are connected with a space between them.
5 and 26, a continuous flow path 27 that communicates with the continuous induction port 22, and a pair of general flow paths 28a and 28b that communicate with each of the general induction ports 23 and 23 individually,
The terminal end of each channel 27, 28a, 28b is made to face above the inclined guide shelf 29' of the winning ball collecting gutter 29 on the back side of the game board 6. According to the embodiment of the drawings, each flow path has a continuous inlet 30 and a pair of general inlets 31, 31 at a position opposite to each guide port 22, 23 of the mounting board 25, and the back side of the mounting board 25. has an inlet 30,3
Edges 32a, 32b, 32c are provided from the opening portion of 1 to form a groove in which the batted ball flows down, and the open end surface of the groove is closed with a back plate 26 to form channels 27, 28a, 28.
b is formed. Since the edge 32c functions as a downstream guide, it is sloped downward to the side opposite to the slope of the slope guide shelf 29', as shown in FIG.

Each flow path 27, 28a, 28b has a shaft 3.
Ball bearing members 34a, 34 swingably supported at 3

The detection switch 35 is located within the swing range of 4b and 34c.
Place a, 35b, and 35c. Ball receiving member 34
a, 34b, 34c are detection switches 35a, 35
The spring action of each operating protrusion 35' of b, 35c always rotates upward to close each flow path 27, 28a, 28b, and tilts downward due to the weight of the winning ball flowing down from the inlet ports 30, 31. When the ball is tilted sufficiently, the winning ball is released into the channels 27 and 28. The ball receiving member 34c functions as a downstream guide part together with the edge 32c, and in order to convert the downstream direction of the ball to the inclined upstream side of the inclined guide shelf 29',
The end of the inclined guide shelf 29' located on the downstream side of the slope is pivoted, and the other end of the inclined guide shelf 29' located on the upstream side of the slope is configured to be able to be lowered.

The outlet ports 27', 28a', and 28b' located at the terminal ends of the flow paths 27, 28a, and 28b open in different directions, as shown in FIG. For example, when looking at the variable winning device 13 from the back side, the central outlet 27' extends downward, the left outlet 28a' extends diagonally downward to the left like the inclined guide shelf 29', and the right outlet 28b' opens diagonally downward to the right, opposite to the direction of inclination of the inclined guide shelf 29', and the winning balls falling from each outlet 27', 28a, 28b' are directed to the inclined guide shelf 29 of the winning ball collecting gutter 29. The structure is such that the objects do not fall concentratedly in the same direction. Therefore, in FIG. 4, the winning balls that flowed out of the outlet 27' fall in a nearly vertical direction, and the winning balls that flowed out of the outlet 28a' fall while tilting slightly to the left, and fall toward the outlet 28.
The winning balls flowing out from b' fall to the right side, that is, toward the upstream side of the inclined guide shelf 29', and due to this dispersed outflow, a large number of winning balls are delivered to the variable winning device 13 within a very short time. Even if a ball hits a prize, the time it takes for these winning balls to flow down to the winning ball flow down controller 29'' provided at the lower end of the slope of the inclined guide shelf 29' is varied, so that the rectification is smooth and the winning ball is won. The balls will not become clogged in the ball collection gutter 29, especially near the entrance of the winning ball flow down controller 29''.

The engaging arm 20 of the door plate 18 described above is attached to the mounting board 25.
The other end of the actuating piece 36, one end of which is rotatably supported on the mounting board 25, is engaged from above with the protruding rear end of the actuating piece 36. The tip of the operating rod 37a of the electric drive source 37 attached to an appropriate position such as the back surface of the game board 6 or the back surface of the mounting board 25 faces from above. Therefore, when the drive source 37 is demagnetized, the door plate 18 stands up to block the ball entrance 117, as shown by the dashed line in FIG. 5, and enters the first state in which it does not accept a batted ball. In addition, when the drive source 37 is excited, the door plate 1 is shown as a solid line in FIG.
8 rotates in front of the base plate 16 to open the ball entrance 17 and enter a second state in which it is easy to receive a batted ball.

On the inner surface 18' of the door plate 18 described above, as shown in FIG. 6, a large number of ribs 38 extending orthogonal to the length direction are provided in parallel. The height of these ribs 38 is set individually, and the two ribs 3 near the end of the door plate 18
8a and 38a are the highest, and gradually become lower toward the center of the door plate 18. Furthermore, the ribs 38 at both end portions of the door plate 18 are also lower than the upper rib 38a.
Therefore, on the inner surface 18' of the door plate 18, there is a first guide surface 39 that slopes downward toward the continuous inlet 30 by the upper surface of each rib 38, and the left and right general inlets 3.
2nd guide surfaces 40, 4 that slope downward toward 1, 31;
0, the first guide surface 39 has a width equal to the distance between the two highest ribs 38a, and each second guide surface 40 has a width from the rib 38a to the side edge of the door plate 18. be. Therefore, the ball continues to be hit at the inlet 3.
The width 1 ₁ of the first guide surface 39 formed as a guide slope portion for guiding to zero is sufficiently longer than the width 1 ₂ of the second guide surface 40 . However, the widths 1 ₁ and 1 ₂ can be set appropriately by adjusting the height of each rib 38 when forming the door plate 18.

In addition, 41, 41 is a sub-winning hole of the variable winning device 13, and the batted ball that wins in the sub-winning hole 41 is discharged into the winning ball collection gutter 29 through an outflow path 42 formed on the back surface of the mounting board 25. , becomes the winning ball.

As shown in FIG. 1, the variable winning device 13 having the above-described configuration is attached to the lower part of the gaming section 8 of the pachinko machine 1, and each detection switch 35... and drive source 37 are connected to an electric control device 43. connected.

In the pachinko machine 1 shown in FIG. 1, when a batted ball enters a specific winning opening 10, a detector (not shown) provided in a flow path communicating with the specific winning opening 10 detects the hitting ball, and a display section 11 To convert and display multiple numbers etc. displayed at high speed. The converted and displayed numbers stop being converted and displayed when a stop switch (not shown) is operated, or when a certain period of time has elapsed when the stop switch is not operated, and the numbers, etc. are displayed statically. If the combination of numbers, etc. forms a specific prize mode, the drive source 37 is energized for a certain period of time via the electric control device 43 to start a special game. For example, if all four numbers on the display unit 11 display "7", "7", "7", "7",
The electric control device 43 controls the drive source 37 to a maximum of 30
Excite for seconds. When the drive source 37 is excited, the operating rod 37a rises against the bias of the wound spring 37b, making the operating rod 36 freely rotatable. When the operating rod 36 is in this state, the door plate 18 rotates forward by its own weight and stops in a slightly downwardly inclined state toward the ball inlet 17, thereby opening the ball inlet 17. For this reason, the batted ball flowing down inside the gaming section 8 is
It is received on the inner surface 18', that is, the upper surface, of the door plate 18,
While rolling on this upper surface, it is guided to the rear end of the door plate 18 and placed on the branching part 24, and due to the downward slope of the branching part 24, it is connected to either the inclined inlet 30 or the general inlet 31.
are distributed to guide ports 22 and 23, respectively. At this time, the batted ball received by the first guide surface 39 of the door plate 18 rolls toward the center of the door plate 18 due to the downward slope of the first guide surface 39, and rolls toward the center of the door plate 18.
8, the probability of entering the continuation guide port 22 located approximately in the center of the ball inlet 17 and flowing into the continuation inlet port 30 is increased. In addition, the door plate 18
The batted ball received by the second guide surfaces 40, 40 is guided to the rear end of the door plate 18 while rolling on the second guide surface 40. , 23 and directly flows into the general inflow ports 31, 31.

The batted ball that has entered the continuous inflow port 30 is transferred to the mounting board 2
5, the ball receiving member 34a is tilted, and the ball is discharged through the continuation channel 27 into the winning ball collection gutter 29 while being detected by the continuation switch, and becomes a winning ball. Further, the batted balls that have flowed into the general inlets 31, 31 are also discharged into the winning ball collection gutter 29 through the general channels 28a, 28b while tilting the ball receiving members 34b, 34c, and become winning balls.

Then, when the winning ball tilts the ball receiving member 34,
Each detection switch 35 is temporarily turned on, and this signal is transmitted to the electrical control device 43.

In the electrical control device 43, each detection switch 35
The signals from a, 35b, and 35c are individually counted and processed, and when the total count reaches a certain number, the drive source 37 is demagnetized on the spot, and the variable prize winning device 13 is changed from the second state to the second state. The special game is controlled to return to the 1 state and end the special game.

On the other hand, the detection switch 35 facing the continuous inflow port 30
The signal from a is specially processed by the electrical control device 43. That is, it is determined whether the special game continuation condition is met based on the presence or absence of a signal from the detection switch 35a.

As for the game mode of the variable winning device 13 described above, for example, as a condition for ending the operation in the second state in the first round, the total number of winning balls that have flowed into the ball entrance 17 becomes 10, or the The variable prize winning device 13 is changed from the second state to the first state in accordance with the end condition that is achieved first of both end conditions when the conversion duration from the first state to the second state reaches 30 seconds. It is set to convert. Therefore, during the first operation time, the continuous inlet 30
If no ball is hit in the game, all the actions, ie, the special game, are completed when the first action is completed.

Then, during the first operation time, the continuous inlet 3
If one or more batted balls win a prize at 0 and the continuation condition is met, after the first operation is completed, the variable prize winning device 13 again converts from the first state to the second state and returns to the second state.
The second operation is started, the second operation is finished under the same termination conditions as the first operation, and the next operation continues in sequence.

This continuous operation is set to a maximum of 9 times, and from the first operation to the 10th operation in total,
Even if 10 or more batted balls enter the continuous inflow port 30, all operations are completed at the end of the 10th operation, and the variable winning device 13 returns from the second state to the first state. .

Note that the game modes set in the electrical control device 43 are not limited to those of the above-mentioned embodiments,
Various embodiments are possible. In addition, the number of inflow ports of the variable winning device is not limited to three as shown in the embodiment, and any variable winning device with at least two or more inflow ports is sufficient. Various aspects of the flow path are also possible. Further, the downstream direction guide part in the embodiment is made up of the ball receiving member 34c and the edge part 32c, but is not limited thereto, Any structure may be used as long as it has the function of discharging winning balls.

<Effects of the invention> As explained above, according to the invention, the variable prize winning device is provided with a flow direction guide portion in at least one of the plurality of flow paths, so that the winning balls flowing out from this flow path are The ball temporarily moves toward the upstream side of the inclined guide shelf of the winning ball collection gutter due to the action of the downstream guide section. Therefore, the winning balls that flowed out from this flow path will no longer be stored in the same part on the inclined guide shelf, and the time required to reach the winning ball flow down controller and the winning balls that flowed out from other flow paths will be reduced. A difference occurs in the time required for the balls to reach the ball flow lower controller, and the rectification state of these winning balls becomes smooth. For this reason,
Even if a large number of batted balls enter the variable prize winning device intensively within a very short period of time, these winning balls can flow down in a rectified state on the inclined guide shelf of the winning ball collection gutter, and the winning balls are It is possible to eliminate clogging of balls on the inclined guide shelf of the collection gutter, especially clumping of winning balls near the entrance of the winning ball flow down controller.
