Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pachinko game machine, and particularly to a new pachinko machine that has been improved so that a large amount of prize balls can be awarded to a player when a certain gaming state is reached. Regarding gaming machines.

[Prior Art] In general, pachinko gaming machines (hereinafter referred to as pachinko machines) that use pachinko balls to play games are widely used and are popular among players as one of the convenient cash registers. As is well known, a pachinko machine has a plurality of safe holes and a winning ball device (Yakumono; commonly known as a chulip) arranged on the board, and when a player drives a pachinko ball along the board, the pachinko machine If the ball lands in the safe hole or Yakumono with a certain probability,
A fixed number of prize balls are paid out. In order to improve services to players, conventional pachinko machines open a predetermined number of yakumonos when a ball hits a certain safe hole or winning area, or Time was opening up. For this reason, in the past, even if prize balls were awarded depending on the pachinko playing state, players would only be able to win prize balls for a predetermined number or for a predetermined time based on winnings in a specific winning area. If you want to win a large amount of prize balls by playing until the machine stops, you need excellent gaming skills and the durability to withstand continuous gaming for long periods of time. Therefore, many skilled pachinko players, known as pachinko players, were able to win a large number of prize balls from one pachinko machine until it was stopped.

[Problems to be Solved by the Invention] However, as a game hall, it is important to provide not only specific players but also many players with a wide opportunity to win a large amount of prize balls, although the appearance probability is relatively low. There is a desire to standardize services for all players. In addition, conventional pachinko machines
Since the game is only won based on the winning balls placed in the center winning area provided at the center of the game board or the winning balls placed in the specific safe holes formed on the game board, the game It's easy to get bored with people. Therefore, there is a need for a pachinko machine with a new way of driving the winning ball device.

Therefore, an object of the present invention is to provide a service in which the winning ball device has a new driving method, which is easy to attract players' interest, and which also provides a wide range of opportunities for general players to win a large number of prize balls. It is an object of the present invention to provide a new pachinko machine that can achieve uniformity of the game.

[Means for Solving the Problems] A pachinko game machine according to the present invention is arranged on a game board of the pachinko game machine, has a ball receiver that can be opened to an expanded state, and has a ball receiver that can be opened to an expanded state. a variable winning ball device that receives falling pachinko balls and guides them to a winning area when the pachinko balls are opened; a first special prize area that is determined to give a relatively small value according to the passing of the pachinko balls; an opening/closing drive mechanism that drives the ball receiver of the variable winning ball device to open in response to a pachinko ball that has passed through the first special prize area and keeps the ball receiver in an expanded state until a relatively small value is given; a second special prize area that is determined to give a relatively large value according to the passing of balls; a predetermined number of winning balls detecting means for detecting that the number of winning balls in the entered prize area has reached a predetermined number; and driving the ball holder of the variable winning ball device to open in response to the pachinko balls that have passed through the second special prize area, and maintaining the expanded state of the ball holder until an output from the predetermined number of winning balls detecting means is received. The invention is characterized in that it is equipped with an opening driving means.

[Function] In this invention, when the pachinko balls pass through the first special prize area, the ball receiver of the variable winning ball device is controlled to be in the expanded state until a relatively small value is given. When the pachinko balls pass through the second special prize area, the ball receiver of the variable winning ball device is driven to open, and the number of winning balls in the winning area formed in the variable winning ball device reaches a predetermined number. The expanded state of the ball holder is maintained until the ball is reached.

In other words, the ball receiver of the variable winning ball device is opened based on the winning balls in the first and second special prize areas, and a relatively large number of pachinko balls can be won.
Depending on the type of special prize area in which the hit ball wins, the termination conditions for ending the open state of the variable winning ball device and bringing the ball receiver into the closed state vary, and the gaming value given to the player varies. The quality is different.

FIG. 6 is a control circuit diagram for controlling the game of the pachinko game machine of the present invention. Next, the operation of the present invention will be explained with reference to FIGS. 1 to 6.

First, when the hit ball enters the safe hole 12, the ball receivers 33a, 33b are opened, and the ball receivers 33a, 33 are opened based on the winning ball entering the winning hole 35.
Let us now discuss the case of closing b. Driving ball is safe hole 1
2, the winning ball is guided to the passage 463 via the path 211. This winning ball is in aisle 463
When passing through, the ball rests on the ball mounting portion 472 of the rotating lever 47, and the weight of the ball causes the lever 47 to rotate counterclockwise. At this time, the engagement pin 413 engaged with the other end 473 of the rotary lever 47 is pushed upward as the rotary lever 47 rotates.
As a result, the engagement pin 413 presses the lever 43 while coming into contact with the arcuate portion 432 of the lever 43. When the engagement pin 413 is pushed up to the upper position, the engagement pin 413 and the protrusion 433 of the lever 43 engage with each other, thereby locking the engagement pin 413. At this time, when the engagement pin 413 is pushed upward, the lever 41 rotates clockwise around the cylindrical part 411, thereby rotating the cylindrical shaft 331 that is fitted and fixed to the cylindrical part 411. to rotate the ball receiving portion 33a outward.
At the same time, the lever 42 that is loosely fitted with the engagement protrusion 412 is rotated counterclockwise, so that the cylindrical shaft 33 that is inserted through and fixed to the lever 42 is rotated counterclockwise.
1' is rotated, thereby rotating the ball receiving portion 33b outward. In this way, the ball receiving part 33
a, 33b are opened.

When the ball receivers 33a, 33b are rotated outward and opened, pachinko balls can enter the winning hole 35 and winning area 32 that were previously covered by the ball receivers 33a, 33b. Then, the pachinko balls hit by the player move to the guide protrusions 37a, 37.
between b or between guide protrusions 37a and 38a,
Alternatively, it falls through between 37b and 38b and falls into the winning hole 35. In response, the winning ball is guided to the side via the path 314, placed on the ball mounting piece 435 of the lever 43, and is released from the through hole 452 by rotating the lever 43 clockwise. This rotation of the lever 43 causes the engagement pin 413 and the protrusion 4 to
33 is released, the lever 41 rotates counterclockwise, and accordingly, the ball receivers 33a and 33b are rotated inward to close them. As a result, when one winning ball enters the winning hole 35 with the ball receiving parts 33a and 33b open, the ball receiving parts 33a and 33b are immediately closed.

On the other hand, when a pachinko ball hit by a player passes between the guide protrusions 37a and 38a or between the guide protrusions 37b and 38b and reaches the ball receiving part 33a or 33b, the pachinko ball hits the ball receiving part 33a or 33b. Part 33
a and 33b to the lower winning area 32
The player is guided to the back side of the game board via the winning area 32. At this time, ball receivers 33a and 33b
Since the pachinko balls guided by do not rotate the lever 43 at all, the pachinko balls that have won into the winning area 32 do not close the ball receivers 33a and 33b. Therefore, no matter how many pachinko balls are guided to the winning area 32 by the ball receivers 33a and 33b, the ball receivers 33a and 33b are not closed and remain continuously opened. .

In this way, the ball receiving parts 33a and 33b are opened according to the winning balls in the safe hole 12, thereby making it possible for the balls to enter the winning area 32 and the winning hole 35, and pachinko balls to the winning area 32. As long as the player wins a prize, the ball receivers 33a and 33b are not closed at all, and the player is given an opportunity to win a large amount of prize balls. If a player unfortunately wins a prize in the winning hole 35, the ball receivers 33a and 33b are immediately closed, and the state changes from a state in which it is easy to win a prize to a state in which winning is prohibited. After that, no matter how much the ball passes between the guide protrusions 37a, 37b, 38a, 38b, it is bounced by the outer arc portions of the ball receivers 33a, 33b and goes into the winning ball area and the winning hole 35. I am not given the opportunity to win.

Next, an explanation will be given of the operation in the case where the ball receivers 33a and 33b are opened until the maximum value, which is a feature of the present invention, is given by the ball hitting the second special prize area 14. A second special prize area 14 is located at a position (directly below the variable winning ball device 30 in the illustration) where it is difficult for the player to win even if he or she aims for it, and therefore there is a certain chance of winning. is formed. If the ball is lucky enough to land in this special prize area 14, the special prize ball will be detected by the special prize ball detection switch 24 as it falls through the path 215.
When the special prize ball detection switch 24 detects a special prize ball,
The detection output is a flip-flop (hereinafter referred to as FF)6
Set it to 1. This FF61 set output is
It is given as one input to the AND gate 62 and also given as an operation command signal to the timer 63. This timer 63 starts from the time when the operation command signal is given to the ball receivers 33a and 3 of the variable winning ball device 30.
The "H" signal is derived for a relatively long period of time (for example, 20 to 30 minutes) so that 3b can be opened, and the "H" signal is sent to the AND gate 6.
2 as one input. AND gate 62
, a counter 6 is an example of a means for detecting the number of winning balls.
The count-up output ("H" signal) of No. 4 is inverted to a low-level (hereinafter "L") signal and given as the remaining input, but since the counter 64 does not derive the count-up output in the initial state,
The AND gate 62 derives an "H" signal. The solenoid 51 is energized by the "H" signal output from the AND gate 62. In response to this, by pulling down the L-shaped lever 53, the rotating lever 47 is rotated electrically.
The ball receivers 33a and 33b are opened in the same manner as the above-mentioned operation.

Then, the ball receiving part 33 is opened to the expanded state.
When the winning ball is guided to the winning area 32 through paths a and 33b, the winning ball is guided to the winning ball processing device 22 via paths 314 and 216. When the winning balls are dropped one by one by the winning ball processor 22, the winning ball detection switch 224 detects the winning balls and gives a counting command signal to the counter 64. This counter 64
is a relatively large predetermined number of winning balls (for example, 100)
The output is used as an L signal until it is counted. Therefore, the AND gate 62 remains active until either the timer 63 has elapsed for a relatively long preset period of time or the counter 64 has counted a relatively large predetermined number of winning balls, whichever comes first. , thereby causing the solenoid 51
Continuous energization control. Therefore, the hit ball enters the winning area 32 with a relatively high probability. At this time, even if the hit ball enters the winning hole 35, the solenoid 51 is continuously energized to hold the rotating lever 47 in a rotating state.
a and 33b remain open continuously.

Then, a time-up signal (signal that inverts from high level to low level) is derived by counting a certain period of time after the timer 63 is activated, or the counter 63
The output of the AND gate 62 is inverted to a low level by counting a predetermined number of winning balls having a relatively large number of 4 and deriving a count-up output (a signal inverted from a low level to a high level). As a result, the solenoid 51 is deenergized and turned off, and the ball receivers 33a and 33b are closed.

In other words, when the special prize ball detection switch 24 detects a special prize ball, the solenoid 51 is energized and turned on, and the ball receiving parts 33a and 33b are opened.
Then, the solenoid 51 is deenergized and turned off based on the output of the timer 63 counting a certain period of time or the counter 64 counting a predetermined number of winning balls, whichever comes first, and the ball receiver 33a, 33
b is closed.

The FF 61 and the counter 64 are reset or cleared by a differentiated pulse obtained by differentiating the time-up output of the timer 63 (a signal that inverts from high level to low level) by a differentiating circuit 65. Therefore, the FF 61 and the counter 64 can return to their initial states and prepare for the next input. The differentiating circuit 65 is a differentiating circuit that performs falling differentiation, as indicated by the signal (-) in the figure, and does not perform rising differentiation of a signal that is inverted from a low level to a high level. This is to prevent the differential pulse from being output when the timer 63 operates.

In the description of the above-mentioned embodiment, the embodiment in which the winning ball detection switch 224 is provided in the vicinity of the winning ball processing device 22 has been described. In such an embodiment, in the maximum value imparting state (the gaming state when the pachinko ball passes through the second special prize area 14),
The winning ball detection switch 224 detects not only the number of pachinko balls that have won in the variable winning ball device 30 but also the number of pachinko balls that have entered other winning areas and winning holes. Therefore, in the maximum value imparting state, the winning ball hit by the player is the variable winning ball device 3.
Since the ball is counted not only when it is zero but also when it enters any prize area, the number of prize balls that can be given to the player when the maximum value is awarded can be made equal as a result.

In addition, as mentioned above, the winning ball detection switch 224 is not limited to the vicinity of the winning ball processing device 22, but may be provided at another location, for example, in relation to and near the path 214. In this case, in the maximum value imparting state, only the number of winning balls that have won in the variable winning ball device 30 can be detected, and the number of winning balls that have won in the variable winning ball device 30 can be detected by a predetermined number (for example,
10 balls), the variable winning ball device 30 may be controlled to close.

In addition, in FIG. 6, after a relatively long time set by the timer 63 after the detection of the special prize ball, or after the counter 64
The solenoid 51
During this period, the ball receivers 33a, 33b are securely
Although the case where the winning balls are won has been described, the control may be controlled only by counting a predetermined number of winning balls by the counter 64. In addition, as another method, the number of profitable balls (number of out balls or number of balls hit) that is profitable for the gaming hall and the number of disadvantageous balls that are disadvantageous to the gaming hall (number of winning balls or number of supplementary balls) ) is detected and the solenoid 51 is energized and controlled until the difference between the number of profitable balls and the number of disadvantageous balls becomes constant. ,33
b may be controlled to open.

By the way, in the above embodiment, the solenoid 51
Although the case where the ball receiving parts 33a and 33b are electrically opened using the above-mentioned method has been described, various other modifications can be considered as a method of providing maximum value.

Figures 7A and 7B are back illustrations showing other examples of the variable prize winning ball device which is a feature of the present invention, in particular, Figure 7A shows the normal state, and Figure 7B shows the maximum value giving state. .

A safe hole 82, which is an example of a first special prize area, is formed on the game board 81 of the pachinko machine 80 of this embodiment, and the winning balls that have entered the safe hole 82 are guided to the passage 463 on the back side of the safe hole 82. A path 83 is formed. In addition, at the top of the game board 81, there is a second special prize area 8 with nails adjusted so that it is relatively difficult to win.
4 is formed. On the back of the first special prize area 84,
A path 85 is formed that guides the special prize balls won into the second special prize area 84 to the special prize ball passage 712.

Next, the operation of this embodiment will be explained with reference to FIGS. 7A, 7B, and 8. Safe hole 82
The operation when opening the ball receivers 33a and 33b based on the winning balls is the same as that of the variable winning ball device 30 described above, and will therefore be omitted. Therefore, to explain the case where the hit ball lands in the second special prize area 84, the special prize ball that wins in the second special prize area 84 is guided to the special prize ball passage 712 via the path 85, and the rotating lever 72 is moved. The rotating lever 7 rests on the ball mounting part 722.
Rotate 2 clockwise. At this time, the other end of the rotary lever 72 engages with the engagement pin 413 and moves the engagement pin 413 upward.
The ball receiving portions 33a and 33b are opened. At the same time, the engaging pin 723 of the rotary lever 72 engages with the hook-shaped portion 731 of the hook-shaped holding member 73 and is locked, so that the ball receiving portions 33a and 33b continue to be opened from now on. Note that the closing of the ball receivers 33a and 33b is continued until the pachinko machine 80 is controlled to stop. It is restored by manually releasing the engaged state.

In this embodiment as well, the ball receivers 33a and 33b can be opened continuously by mechanical drive until a relatively large number of prize balls are awarded, giving the player an opportunity to win a large number of prize balls. There are advantages. In addition, a rotating lever 72 and a hook-shaped holding member 73
Since it is mechanically driven by the ball receivers 33a, 3
There is also the advantage that the structure for opening 3b is simple and inexpensive.

[Effects of the Invention] The present invention having the above configuration drives the ball receiving part of the variable winning ball device to open in accordance with the number of balls passing into the special prize area, and allows a relatively large predetermined number of winning balls to enter the winning area. A new pachinko game machine is obtained in which the expanded state of the ball receiving part is maintained until the end of the game. By this,
In order to win a large number of prize balls with a relatively high probability, the player plays the game by aiming the ball to land in the special prize area, and after the ball passes through the special prize area, a relatively large predetermined number of balls are awarded. Since the ball receiver is kept open until the winning balls pass into the winning area, the player can easily win many prize balls in a short time, and since the winning balls are generated continuously, it is easy for the player to It has the effect of allowing you to repeatedly experience the sensation of pleasure. As a result, services including general players can be made uniform, making it easier to attract the interest of a wide range of general players, and also having the effect of improving the operating rate of pachinko gaming machines.
