Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pinball game machine represented by a pachinko game machine, etc., and specifically relates to a pinball game machine in which a special prize area is formed on the game board. .

[Prior Art] This type of pinball game machine has been generally known in the past, in which a predetermined number of prize balls can be won by pachinko balls landing in a special prize area formed on a game board. Some games were designed to give a certain value to the player, such as by paying out a prize or by controlling the probability of winning a ball to be advantageous to the player.

[Problems to be Solved by the Invention] However, the conventional pinball game machine releases prize balls in the same way as regular winning balls when they enter a special prize area where a certain value is given to the player. It was recovered on board the aircraft to be used for future work. For this reason, if the player determines that a certain value will be given as a result of the ball hitting the special prize area, the game will be canceled if that certain value is not given. This creates a sense of distrust among players and causes trouble between players and game hall staff.

In view of the above circumstances, it is an object of the present invention to provide a pinball game machine with a simple configuration that can prevent troubles regarding whether or not a player wins a prize in a special prize area in which a certain value is given. .

[Means for Solving the Problems] A pinball game machine according to the present invention includes: a special prize area formed on a game board; a special prize ball detection means for detecting a winning ball that has entered the special prize area; and a special prize ball. A value imparting means that imparts a certain value to the player based on the output of the detection means; A winning ball storage means that stores the winning balls that have won in the special prize area; and Winning balls stored in the winning ball storage means. It is characterized by being equipped with a display window that allows the user to see through the display window.

[Function] According to the present invention, if the ball landed in the special prize area, a certain value is given to the player by the action of the value giving means. Then, by the action of the winning ball storage means, the winning balls that have won in the special prize area are stored, and the stored winning balls can be seen through the display window.

In other words, the winning balls that have won in the special prize area where a certain value is given to the player are stored by the winning ball storage means and can be viewed by the player from the display window, which serves as evidence that the winning ball has been won in the special prize area. The presence or absence of winning balls can be visually confirmed from the display window.

It is configured by forming a path 464 along the perpendicular direction in a plate member 461. Below this path 464,
The special prize ball detection switch 44 is provided.

Below the special prize ball detection switch 44, the 3rd B
A special prize ball storage mechanism 47 is provided as shown in detail in FIGS. 3C, 3C, and 4. The special prize ball storage mechanism 47 includes a rotating lever 471. Rotating lever 47
1 is formed in a "he" shape, and the fulcrum 4 is positioned so that its long side is located below the special prize ball detection switch 44.
It is rotatably supported at 72. Rotating lever 471
When there is no one special prize ball, the tip of the long side is at the stopper wall 473, as shown by the solid line in Fig. 3C.
Waiting for the prize ball while touching the ball. When the special prize ball passes along the long side and reaches the short side, the rotating lever 471 is rotated clockwise because the short side is pushed down by the weight of the ball. A protruding wall 747 is formed opposite to the rotating lever 471 . The upper end portion of the protruding wall 474 is connected to the rotating lever 7.
When 41 rotates, it engages with the tip of the long side and functions as a stopper. A solenoid 475 is provided near the short side of the rotation lever 471. The solenoid 475 is of a so-called double action type, and includes a coil (475a shown in FIG. 7, which will be described later) for moving the plunger 476 toward the rotating lever 471 side by its urging, and a coil (475a shown in FIG. 7, which will be described later) in the opposite direction. It includes a coil to be moved (475b shown in FIG. 7, which will be described later). And solenoid 475
The excitation state of each coil is determined by the left end of the plunger 476 and the rotating lever 47 when the state is not a specific game state.
The distance between the ball and the short side of the ball is set to be larger than the diameter of one ball, and in a specific game state, the space is set to be smaller than the diameter of one ball. Therefore, the tip of the long side of the rotating lever 471 is connected to the protruding wall 47.
The plunger 47 rotates to a position where it engages with the plunger 47.
6 protrudes toward the rotating lever 471 side, the special prize balls are stored at a position sandwiched between them. In this state, the display window 6 is formed in front of the storage position of the special prize balls. Therefore, in a specific game state, the special prize area 43a
The winning prize balls are stored at a position sandwiched between the rotary lever 471 and the plunger 476. Therefore, the player can see the special prize balls through the display window 6, and has the advantage of being able to confirm that a winning ball has been placed in the special prize area 43. The special prize ball storage mechanism 47
This constitutes a winning ball storage means for storing winning balls that have won into the special prize area.

A path 465 is formed in the plate member 461 below the rotation lever 471. The path 465 functions to guide the winning ball downward into the special prize area 43a after the first special prize ball is won in a specific game state.

In addition, in the illustration, as an example of a variable winning ball device, there is a state in which balls are easily won as a state that is advantageous to the player, and a state that does not allow balls to win as a state that is disadvantageous to the player. However, it goes without saying that various other variable winning ball devices may be used. For example, as another example of a variable winning ball device, there is a so-called chulip, in which a pair of ball receiving pieces are opened on the left and right sides to make it easier for the player to win the ball. As a disadvantageous condition for the player, the ball receiving piece may be closed to make it difficult for the player to win a prize.

Next, details of the variable display device 50 will be described. Variable display device 50 includes a rotating drum display mechanism 50A and a segment display 50B. The rotating drum display mechanism 50A is constructed as shown in FIG.
That is, the rotating drum group 51 includes multiple rows of rotating drums 51a, 51b, and 51c. Identification information such as a picture pattern, a symbol, or a number (for example, a picture pattern such as a bell, a star, a yacht, or a number or a symbol such as an alpha alphabet) is drawn on the outer periphery of the rotating drums 51a to 51c in each row. Ratchet gears 52a to 52c (only 52c is shown in the figure) having the number of teeth corresponding to the number of identification information drawn on the outer periphery are fixed to the respective side surfaces of the rotating drums 51a to 51c in each row. Rotating drum 51 in each row
Each of a to 51c is loosely fitted onto the drum shaft 53 and supported so as to be individually rotatable by its frictional force. The drum shaft 53 is pivotally supported on both sides of the box 54. A gear 551 included in the rotational force transmission mechanism 55 is provided at one end of the drum shaft 53.
is fixed. The gear 551 is meshed with a transmission gear 552. A motor 56 for driving the rotating drum is attached to the side surface of the box 54. The motor 56 is a geared motor,
The drive gear is coupled to gear 552. The rotational force of the motor 56 is transmitted to the drum shaft 53 via gears 552 and 551, and drives the rotating drum group 51 to rotate. Furthermore, solenoids 57a to 57c are fixed to the rear rear surface of the box 54 for individually controlling rotation or stopping of the rotating drums 51a to 51c in each row. Plungers 571 of these solenoids 57a to 57c
are connected to one end of each of the locking levers 58a to 58c by a pin. These locking levers 58a~
A substantially central portion of 58c is supported by a shaft 581.
Both sides of the shaft 581 are fixed to both sides of the box 54. A claw-like portion 582 is formed at the tip of each of the locking levers 58a to 58c. The claw-like portions 582 of each of the locking levers 58a-58c engage with the corresponding ratchet gears 52a-52c, respectively, to stop the rotating drums in each row and maintain the locked state.

The specific game state that allows the variable winning ball device 40 to be in the first state for a relatively long time is a combination of identification information such as a picture pattern in each row displayed on the rotary drum display mechanism 50A. It is determined by a combination of the alignment state and the display state of numerical information displayed on the segment display 50B.

Other examples of the specific game state include only the display state of the rotary drum display mechanism 50A, only the display state of the segment display 50B when a plurality of digits are provided, or a specific winning state provided on the game board 1. The case may be based on any case where there is a ball passing through the area.

FIG. 6 is a game control circuit diagram of an embodiment of the present invention. In the configuration, the game control circuit 60 includes a variable display possible condition detection circuit 61, a rotating drum drive control circuit 62, a display drive circuit 63, a specific game state detection circuit 64, a repeated opening condition detection circuit 65, and a predetermined value provision state detection circuit 66. , and a drive control circuit 70.

Here, the variable display enable condition detection circuit 61 detects a condition that allows the variable display device 50 to display a variable display. The rotating drum drive control circuit 62 drives and controls the rotating drum display mechanism 50A based on variable display enable conditions. The display drive circuit 63 drives the segment display 50B to display based on variable display enable conditions. The specific game state detection circuit 64 detects the display state of the rotating drum display mechanism 50A and the segment display 50.
Based on the combination with the display state of B, it is detected that a predetermined specific gaming state has been entered. In addition,
The specific gaming state detection circuit 65 preferably includes a function of detecting not only the specific gaming state but also a condition in other gaming states that can bring the variable prize winning ball device 40 into the first state. Repeated opening condition detection circuit 6
5 detects that there is a winning ball in the special prize area 43a in a specific game state. The predetermined value provision state detection circuit 66 detects a state in which a predetermined value is given in a specific game state (for example, a state in which a relatively large number of prize balls set as the number of prize balls are given).

FIG. 7 is a detailed circuit diagram of the drive control circuit 70 and the repeated opening condition detection circuit 65. This drive control circuit 70 includes an OR gate 71 and a timer 72.
74, a driver 75, a driving circuit 76 for repeatedly opening and closing for a certain period of time, and a driving circuit 77 for storing and discharging special prize balls. Here, the driver 75 is the or gate 71
By energizing the solenoid 451 during the output period, the variable winning ball device 40 is driven to the first state. The opening/closing drive circuit 76 repeatedly opens and closes for a certain period of time as an example of putting the variable winning ball device 40 into the first state for a relatively long period of time (for example, t1).
= 30 seconds) to make it easier to win continuously.

Next, with reference to FIGS. 1 to 7, specific operations when playing a game with the pachinko game machine 10 of this embodiment will be described. The player puts the balls borrowed from the ball lending machine into the ball waiting bucket 13, adjusts the strength of the ball by rotating the ball handle 14, and then turns the ball into the ball hitting switch 14.
Press s. Electric power is supplied to the motor 241 in response to the depression of the ball hitting switch 14s. depending on,
A motor 241 is rotationally driven and a ball hitting hammer 242 is rotated intermittently to drive balls into the game board 1 one by one. When the player is playing a ball hitting game in this way, if the ball lands in either the safe holes 2a to 2c or the Yakumono 4a, 4b,
The prize ball release mechanism operates to release a predetermined number of prize balls for each winning ball.

On the other hand, when the ball hits any of the winning areas 3a to 3c, the corresponding detection switch 22a, 2
2b derives a high level and applies it to the drive circuit 621 via the OR gate 611 and also to the timer 622. Furthermore, the output of OR gate 611 causes flip-flop 631 included in display drive circuit 63 to be set. Accordingly, the drive circuit 62
1 is by energizing the solenoids 57a to 57c to disengage the claw-like portions 582 of the locking levers 58a to 58c from the corresponding latch gears 52a to 52c, and by driving the motor 56 to rotate. , the rotating drums 51a to 51c in each row are rotationally driven to vary the display state of the rotating drums.
At the same time, the set output of flip-flop 631 is provided as one input of AND gate 632. The output clock pulse of the clock oscillator 633 is always applied to the AND gate 632 as the other input. For this reason, and gate 6
32 derives a clock pulse according to the set output of the flip-flop 631, and outputs a clock pulse to the ring counter 6.
Give to 34. The ring counter 634 controls the segment display 50 in response to the clock pulse input.
B cyclically counts the numerical values 0 to 9 that can be displayed, and the counted value is sent to the decoder driver 63.
5 and a determination circuit 645 included in the specific game state detection circuit 64. Decoder driver 635
decodes the count value of the ring counter 634 and displays the segment display 50 based on the count value.
The numbers displayed at B are sequentially changed in synchronization with the period of the clock pulse. In this manner, the rotary drums 51a to 51c are rotationally driven and the segment display 50B is variably displayed, whereby mechanically variable display and electrically variable display are performed simultaneously.

As described above, the rotating drums 51a to 51c
In a state where the segment display 50B is variably displayed, the player presses the stop command switch 17 so that the combination of display states of the rotating drums 51a to 51c in each row becomes a specific game state. Note that timer 6 starts after variable display starts.
If the stop command switch 17 is not pressed within a certain period of time set by the timer 622, a stop command is issued by the output of the timer 622. In response, the drive circuit 621 deenergizes the solenoids 57a-57c in a predetermined order (or in an irregular order) to sequentially stop the rotating drums 51a-51c. and,
The drive circuit 621 stops the rotation of the motor 56 after a short delay and also derives a high level signal indicating that all rotating drums have stopped.
This high level signal is applied to the flip-flop 631.
is reset, and is also given to the display state determination circuit 643 as a determination command signal. depending on,
AND gate 632 stops deriving clock pulses. Therefore, the count value of the ring counter 634 is not incremented, and therefore, the number corresponding to the count value counted by the ring counter 634 is continuously displayed on the segment display 50B.

The display state determination circuit 643 determines the combination of identification information displayed on the rotating drums in each row based on the outputs provided from the sensors 641 and 642 in response to the determination command signal. By the way, as the sensors 641 and 642, for example, a photoelectric sensor having a light projecting section and a light receiving section is used. Each sensor 6
The light projecting portions and light receiving portions 41 and 642 are provided facing each other on both axially outer sides of all the rows of rotating drums. Although not shown in FIG. 5, on each side surface of the rotating drums 51a to 51c, first circles with different radii and angles corresponding to the identification information displayed on each rotating drum are formed. A portion with a through hole and a portion without a through hole are provided at positions on the circumference and the second circumference. This makes it possible to identify four types of identification information based on the combination of portions with and without holes. For example, if the part with a hole is set to logic ``1'' and the part without a hole is set to logic ``0'', four types of 2-bit codes ``00'' and ``01'' are generated. ,
With "10" and "11", it is possible to detect the combination of identification information of the rotating drums in each row. The display state determination circuit 643 then determines whether the rotating drum 51
A score is determined based on the combination of identification information displayed in a to 51c, and the score is provided to the drive control circuit and determination circuit 645.

If the combination of identification information displayed on the rotating drums 51a to 51c is a combination of a specific game state,
That is, unless the combination is determined to give the maximum value (for example, all symbols are A), the display state determination circuit 643 determines that a value smaller than the maximum value should be given based on the combination at that time. One of the representing determination signals j2 to j4 is derived. Each judgment signal j2 to j4 corresponds to the corresponding timer 7.
2 to 74. Each timer 72, 73, 7
4 are the corresponding judgment signals j2, j3, j
According to the input of 4, the predetermined fixed time t2, t3,
A high level signal is derived only for t4. Here, the fixed time set by the timers 72 to 74 is selected such that t2≧t3≧t4, for example, t2=
10 seconds, t3 = 6 seconds, t4 = 4 seconds are selected. Note that, if the determination signal is other than j1 (i.e., j2 to j4), the determination circuit 645 determines that the segment display 50B
The display status of is not determined at all.

For example, assuming that the display state determination circuit 643 derives the determination signal j2, the timer 72 derives a high level signal for a certain period of time t2. This high level signal is applied to the driver 75 via the OR gate 71. In response, the driver 75 continuously energizes the solenoid 451 for a certain period of time t2. Therefore, the opening/closing plate 41 of the variable winning ball device 40 is opened for a certain period of time t2 to allow the hit ball to win. At this time, the ball is in the winning area 43
When a prize is won in a or 43b, a prize ball discharging mechanism releases a predetermined number of prize balls according to the winning ball. However, even if a ball enters the special prize area 43a, the opening operation of the variable winning ball device 40 is not extended and only a predetermined number of prize balls are released for each winning ball.

Next, a case will be described in which the combination of identification information displayed on the rotating drums 51a to 51c in each row is determined to give the maximum value. In this case, the display state determination circuit 643 derives the determination signal j1 and provides it to the determination circuit 645 and also provides it as a set input to the flip-flop 761. Accordingly, flip-flop 761 is set. Further, the determination circuit 745 receives the determination signal j
1, it is determined whether the count value of the ring counter 634 is in a display state (for example, a state in which 7 is displayed) in which the maximum value set in the combination setting section 644 should be given. At this time, even if the combination of display states of the rotary drums 51a to 51c is a state that provides the maximum value, if the segment display 50B does not display 7, the determination circuit 645 outputs the maximum value provision command signal j0 ( high level). In this case, the set output of flip-flop 761 set by determination signal j1 is applied to timer 763 via OR gate 762. In response, the timer 763 starts counting operation for a certain period of time t1, derives a high level signal during that period, and supplies it to the driver 75 via the OR gate 71. In response, driver 75 operates solenoid 45
1 to open the opening/closing plate 41. At this time, the output of timer 763 is also given to AND gate 771 . However, the high level from the output Q of the flip-flop 764 is not applied to the other input of the AND gate 771. Therefore, AND gate 771 remains disabled.
Therefore, monostable multi 772 is plunger 4
A signal for moving 76 toward the rotation lever 471 is not derived. On the other hand, the determination signal j1 is applied to a monostable multi-channel 774 via an OR gate 773. In response, the monostable multi 774 generates a signal to move the plunger 476 to the position indicated by the dashed line in FIG. A signal indicating what to do is provided to driver 775. In response, driver 775 connects solenoid 475
energizes the coil 475b included in the coil 475b. Therefore, the plunger 476 is moved to a state where it does not store any special prize balls. In addition, immediately before that, if the plunger 476 is in a position where the special prize balls cannot be stored, the plunger 476 will not move even if the coil 475b is energized. As a result, in cases other than the specific game state, even if a ball enters the special prize area 43a, the ball falls downward while rotating the rotating lever 471. In this case, even if the special prize ball detection switch 44 detects a special prize ball and sets the flip-flop 651, the AND gate 652 detects the output Q of the flip-flop 764.
remains immobilized by (low level). Therefore, the repeated opening condition detection circuit 65
The AND gate 652 included in the gate does not repeatedly derive the open command signal. When the timer 763 measures a certain period of time t1, its output is set to a low level, and the opening/closing plate 41 is closed.

Next, when a specific game state is reached, which is a feature of this invention, that is, the combination of display states of the rotating drums 51a to 51c becomes a predetermined state that can give the maximum value (all display states with the symbol A), and When the display state of the segment display 50B reaches a state where 7 is displayed, the following operation is performed. That is, the determination circuit 645 derives a high level signal indicating that a specific gaming state has been established and supplies it to the AND gate 646. At this time, the AND gate 646 detects the predetermined value provision state detection circuit 66
Since the low level of the output of is inverted to the high level, a high level judgment signal j0 is derived. This decision signal j0 causes flip-flop 764 to be set. flipflop 764
The output Q of is given to AND gates 652 and 771. AND gate 771 is timer 763
In response to the presence of the output of the flip-flop 764 and the presence of the output Q of the flip-flop 764, a high level is derived and applied to the monostable multi 772. Monostable multi 772 provides a signal to driver 775 to energize coil 475a. The driver 775 controls the coil 47 in response to the output of the monostable multi 772.
5a is energized. Therefore, the plunger 476 moves toward the rotating lever 471, and the rotating lever 471
The distance between the ball and its tip is made smaller than the diameter of one ball.

In the above state, the ball is in the special prize area 43a.
When a prize is won, the special prize ball detection switch 44 detects it and sets the flip-flop 651. After the special prize ball is detected by the special prize ball detection switch 44, the rotary lever 471 is rotated while rolling along the upper surface of the rotary lever 471. At this time,
The tip of the short side of the rotating lever 471 and the plunger 47
Since the distance from the tip of the display window 6 is smaller than the diameter of the ball, the special prize balls are stored on the back side of the display window 6. Balls that enter the special prize area 43a after that are sent to the rear path 465 detected by the special prize ball detection switch 44.
It falls downward through the. These balls are used for the prize ball discharging operation in the same way as normal winning balls.

If at least one ball enters the special prize area 43a before the timer 763 times up, the variable winning ball device 40 is repeatedly driven to open as described below. That is, timer 76
3 times out, the driver 75 de-energizes the solenoid 451. Therefore, the opening/closing plate 41 is temporarily closed. At the same time, the differentiation circuit 765
differentiates the time-up output and provides the differentiated pulse to the monostable multi 766. monostable multi 76
6 derives a high level for a certain period of time and supplies it to AND gate 652 and delay circuit 767. The AND gate 652 determines that there is an output of the flip-flop 651 (that is, that there is at least one special prize ball during the opening period of the variable winning ball device 40), and that there is an output Q of the flip-flop 764 (that is, that there is a specific game state). ), and in response to the output of the monostable multi 766,
Derive the high level. The output of AND gate 652 passes through OR gate 773 to monostable multi 77
given to 4. Therefore, monostable multi 774
causes the driver 775 to energize the coil 475b. In response, the plunger 476 is moved so that it cannot store the special prize balls. As a result,
The special prize balls stored on the back side of the display window 6 are dropped, and the rotating lever 471 is returned to its original position. Thereafter, the output of the AND gate 652 is given to the timer 763 via the delay circuit 76a and the OR gate 762, so the timer 763 again opens the variable winning ball device 40 for a certain period of time. Also, after a certain time delay from the output of the monostable multi 766, the delay circuit 7
67 causes flip-flop 651 to be reset.

Thereafter, in the same way, special prize area 4 after a specific game state
As long as there are winning balls in 3a, the variable winning ball device 40 can be driven to open repeatedly for a certain period of time t1. The flip-flops 651, 764, the AND gate 652, the delay circuit 76a, the OR gate 762,
Timer 763, differentiation circuit 765, monostable multi 7
76, the OR gate 71, the driver 75, the solenoid 451, and the variable winning ball device 30 constitute a value giving means that gives a certain value to the player based on the output of the special prize ball detecting means.

In addition, when the variable winning ball device 40 is repeatedly driven to open, the ball is in the special prize area 43a.
If you don't win any prizes, flip-flop 65
1 remains reset. In this case, AND gate 768 derives a high level signal according to the output of monostable multi 466, and OR gate 7
69 to reset flip-flop 764. As a result, the repeated opening and driving operation of the variable winning ball device 40 is thereafter terminated.

In addition, after the specific game state, each time the variable winning ball device is repeatedly driven to open, the ball is moved to the special prize area 43.
If you repeatedly win a, the variable winning ball device 40
The repeated opening drive continues. However, when the predetermined value award state detection circuit 66 detects that a relatively large fixed number of prize balls have been paid out, the detection output causes the flip-flop 764 to be reset via the OR gate 769. This also ends the repeated opening and driving operation of the variable winning ball device 40.

Further, as another embodiment of the drive circuit 70, an AND gate is provided between the OR gate 71 and the driver 75, and a pulse at a constant time interval (for example, 2 seconds) is applied to the other input of the AND gate. The variable winning ball device 40 may be driven to open and close within a relatively long fixed period.

Incidentally, the embodiments shown in FIGS. 6 and 7 described above show a case in which a hardware circuit is used to achieve the operation of the present invention, but the technical idea of the present invention is that a program is implemented using a microprocessor. This can also be done by treatment. In that case,
Those skilled in the art will easily be able to set a program to perform the operations of the circuits shown in FIGS. 6 and 7, so a detailed explanation thereof will be omitted.

[Effect of the Invention] According to the present invention having the above-mentioned configuration, since the presence or absence of a winning ball, which is evidence of winning in a special prize area in which a certain value is given to a player, can be visually confirmed from the display window, winning in the special prize area It has now been possible to provide a pinball game machine that can prevent troubles related to the presence or absence of game players with a simple configuration and can reduce troubles between players and staff as much as possible.
