Description

  The present invention relates to an improvement of a big winning device which is arranged on a game board surface constituting a pachinko gaming machine and is opened at a big hit.

  In the pachinko gaming machine, various board parts such as a winning device (start winning device, large winning device), a windmill, a symbol display device, and an illumination device are provided on the surface of the game board in order to diversify the game contents. For example, the symbol displayed on the symbol display device in the game board starts to change due to the establishment of the start condition that the game ball wins at the start winning opening provided on the game board, and a specific symbol (for example, “777” or the like) The game is configured to shift to a big hit state, which is a special gaming state, by stopping at a three-piece design). In the big hit state, the big winning opening of the big winning device is opened, and a large number of balls are released by repeating this opened state a predetermined number of times based on a predetermined condition.

By the way, there are several types of jackpot states in recent pachinko machines, for example, once a big prize opening is opened for a certain period or until a specified number of game balls are won in the big prize opening When this release operation is made (this one release operation is called 1 round), 15 rounds (15R) release operation is repeated as a jackpot game, and after the jackpot game is over, a probability variation game (hereinafter, a probable game) ) And time-reduced game (hereinafter referred to as “short-time game”), 15R probability change big hit, 7R (7R) after winning the big hit game state 7R probability change and 7R probability change given both short-time game There is a big hit.
Also, the opening time of the grand prize opening is extremely short, for example, 0.4 seconds, and after the two round (2R) big hit gaming state where the number of times of opening of the big prize opening is two, both probable games and short-time games are given as bonus games. There is a promiscuous jackpot that has been awarded, and a sudden jackpot that has been given only a short-time game as a bonus game after the 2R jackpot gaming state has ended.
Note that the probability variation game is a game state in which the winning probability in the big hit game state is higher than that in the normal game state (hereinafter also referred to as a high probability state). The short-time game is a game state in which the opening pattern of a movable prize device such as an electric tulip is extended to increase the probability of establishment of the start condition.
The 2R probability variation jackpot described above is set to an extremely short opening time per winning prize opening, so that it is not possible to expect a ball due to a big hit, but after the big hit is over, it shifts to a probability fluctuation state. For this reason, it is possible to give the player a feeling as if the player suddenly wins the probability variation state, so it is called “surprise (sudden probability variation) big hit”.

Next, in Patent Documents 1 and 2, a horizontally long prize-winning port communicating with a guide chamber provided in the interior and a shaft provided along the lower edge of the prize-winning mouth are vertically supported. A large winning device including an open / close plate that opens and closes a large winning opening and a solenoid that drives the open / close plate is disclosed. In the big hit state, the open / close plate is tilted forward to open the grand prize opening, and the game ball flowing down the game board surface is received by the back surface of the open / close plate and guided to the rear guide chamber. Thereafter, the opening / closing plate is closed at the stage of transition to a predetermined gaming state.
However, since the conventional big prize opening has a simple structure that only opens and closes a single opening / closing plate provided in a single big prize opening, it is easy to get bored by the player, and there is a strong demand for improvement in this respect. It was.
There is also known a prize winning device in which two prize winning openings are spaced apart at different positions on the game board surface, and the opening / closing plates provided in each prize winning opening are individually opened and closed. Regardless of the opening / closing time, the opening / closing operation of each opening / closing plate was performed at the same speed, so that the content of the game was hardly changed, causing the player's interest to be significantly reduced. That is, when the game state is suddenly changed from the normal game state to the probability fluctuation state, the opening / closing operation needs to be performed quickly because the opening / closing plate needs to be opened / closed in a short time without exiting. On the other hand, in the case of 7R jackpot with a ball and 15R jackpot, the opening / closing operation of the opening / closing plate and the closing operation may be slow, but the state suddenly shifts to the probability fluctuation state. It was performed at the same rapid opening / closing speed (for example, 0.4 seconds). For this reason, the opening / closing operation of each opening / closing plate became monotonous, and the game content was poorly changed.
Utility model No. 3063845 JP 2003-299804 A

In the conventional prize winning device having an opening / closing plate (door) for opening and closing the conventional prize winning opening, the opening / closing time of the opening / closing plate is provided even when two prize winning openings provided with the opening / closing plates are provided. Regardless of the length, each opening / closing plate opens and closes at the same speed, so that there is little change in game content, which causes a decrease in the interest of the player.
The present invention has been made in view of the above, and two large winning openings are arranged side by side and close to each other, and doors for individually opening and closing each large winning opening are provided, and the opening operation speed and closing operation of each door are provided. An object of the present invention is to provide a prize winning device, a game board unit, and a pachinko gaming machine that can bring about various changes in game contents by changing the speed according to the progress of the game.

Since the two winning openings are arranged adjacent to each other, if the doors that open and close each winning opening are opened and closed at the same speed, the game content may become monotonous and lower interest. In the present invention, the game content is changed by varying the time required for the opening and closing operations of each door according to the length of the opening time of each door.
Moreover, a special winning device according to the present invention, prior Symbol first door, the first door body and, first door body rotates in the front-rear direction about the rotation shaft provided in one lower A pin protruding laterally from a side plate protruding rearward from the side, and the first drive source is a solenoid including a solenoid body and a plunger protruding and retracting in the front-rear direction from the solenoid body, The first opening / closing mechanism has a long hole in the front part for fitting the pin tightly and movably in the front part, and a rotating member having a shaft part pivotally supported in the vertical direction at the rear part. And the first door body is opened and closed through the pin fitted in the elongated hole by rotating the rotating member about the shaft portion by the retracting operation of the plunger.
Since the first door is driven without a time lag through the first opening / closing mechanism when the solenoid is operated, the first door is suitable when the door opening time is short.

The second door body is moved to the open position by its own weight after the pin is initially pressed upward by the lower inner wall of the recess by raising the front part of the rotating member .
Since the second door is driven with a predetermined time lag through the second opening / closing mechanism when the solenoid is operated, it is suitable for a case where the opening time of the door is long .

  In the present invention, the two big prize winning openings are arranged side by side and close to each other, and doors for opening and closing each big winning prize opening are provided, and the opening operation speed and the closing operation speed of each door are made different to advance the game. Since it is used properly according to the game, various changes can be brought about in the game contents. In particular, since the two doors are arranged close to each other, it is possible to bring about a change in the game content when the two doors behave differently.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

The special symbol displayed on the symbol display device 9 is configured to be in a big hit state when the stop symbol is a predetermined symbol combination, for example, the same symbol combination. In addition, the special symbol is provided on condition that the winning of the game ball is detected at the lower starting port (not shown) through which the game ball is guided by the opening operation of the upper starting pocket 14 of the variable winning device 11 or the electric tulip. The display is scrolled by a random number control or the like, and is varied (variable) for a predetermined time with a predetermined variation pattern and stopped at the symbol. At that time, when two stop symbols become the same on the active line, a reach state occurs, and in this reach state, the last stop symbol on the active line is already stopped. A big hit state occurs when they are the same. In addition, as a special symbol, a numerical symbol, an alphabet symbol, a character symbol, etc. can be used.
A characteristic configuration of the present invention resides in a large winning device 20 including a large winning port 13 disposed below the variable winning device 11.

2, 3, 4, and 5 are a front view, a perspective view, a perspective view showing the internal configuration with the top plate removed, and an exploded perspective view showing the configuration of the special winning device 20 of the present invention.
The grand prize winning device 20 includes a substantially rectangular parallelepiped device main body 21 fitted in a big prize winning device mounting hole provided on the game board surface, and a decorative plate 22 fixed to the front portion of the device main body 21. . The large winning device 20 is assembled by fitting the device main body 21 into the large winning device mounting hole from the front and screwing the decorative plate 22 to the game board surface.
On the front surface of the apparatus main body 21, a first prize-winning port 25 and a second prize-winning port 40 arranged side by side and adjacent to each other, and a lower end for opening and closing each of the first and second prize-winning ports 25 and 40 independently. The first door 26 and the second door 41 that are pivotally supported are disposed.
The first and second doors 26 and 41 arranged on the front surface of the apparatus main body 21 are exposed from a rectangular opening 22 a provided on the front surface of the decorative plate 22.
A first winning opening 25; a first door 26 that opens and closes the first winning opening 25 by rotating in the front-rear direction; a first opening / closing mechanism 27 that opens and closes the first door 26; A first driving source 28 that drives the opening / closing mechanism 27 of the first door constitutes a first door opening / closing unit 29.
A second winning opening 40 disposed adjacent to the side of the first winning opening 25, a second door 41 that opens and closes the second winning opening 40 by rotating in the front-rear direction, and a second door A second opening / closing mechanism 42 that opens and closes 41 and a second drive source 43 that drives the second opening / closing mechanism 42 constitute a second door opening / closing unit 44.

As shown in the exploded perspective view of FIG. 5, the first door opening / closing unit 29 and the second door opening / closing unit 44 are assembled to the lower base member 50 and covered with the upper cover member 60. . On the base member 50, in addition to the first door opening / closing unit 29 and the second door opening / closing unit 44, the passage of game balls that have entered the power supply board 51 and the winning holes 25 and 40 are detected. A right count switch 52 and a left count switch 53 for counting, a magnetic sensor 54 for detecting opening / closing of each door, and the like are arranged.
The first door opening / closing unit 29 is configured to drive the first door 26 to open / close (directly move) without a time lag from the operation of the first opening / closing mechanism 27. The second door opening / closing unit 44 includes a second door opening / closing unit 44. The door 41 is configured to be opened and closed with a predetermined time lag between the operation of the second opening and closing mechanism 42.
For this reason, for example, when the 2R jackpot gaming state occurs, the first door 26 is opened quickly for a short opening time and then quickly closed, while when the 7R or 15R jackpot gaming state occurs, the second door 41 is opened. It can be opened by a slow operation and kept open for a long time, and can be closed by a slow operation even when closed. Therefore, the opening / closing operation patterns of the two doors 26 and 41 arranged adjacent to each other can be made different to give a contrasting impression, and an important change in the progress of the game can be brought about.

In order to realize the operation as described above, the first door opening / closing unit 29 and the second door opening / closing unit 44 according to the present invention have the following configurations.
First, the first door 26 constituting the first door opening / closing unit 29 includes a first door main body 26a that rotates in the front-rear direction around a rotation shaft 26b provided in the lower part, and a first door main body 26a. A side plate 26c that protrudes rearward from one side portion, and a pin 26d that protrudes laterally. The rotating shaft 26b is pivotally supported by a pivotal support provided on the base member 50. The first drive source 28 includes a solenoid body 28b, a plunger 28c protruding and retracting from the solenoid body 28b in the front-rear direction, a slider 28c rod integrated with the plunger, and a coil spring 28d that urges the plunger 28c in the protruding direction. Solenoid 28a. The solenoid 28a is ON / OFF controlled by a control signal from a control means (not shown), and when turned ON, the plunger 28c is retracted against the coil spring 28d.
The first opening / closing mechanism 27 includes a long hole 27b in which the pin 26d is closely and movably fitted, and a shaft portion 27c that is pivotally supported in the vertical direction at the rear portion. A moving member 27a is provided. The shaft portion 27 c is pivotally supported by a shaft support portion provided on the base member 50. By fitting the pin 28e provided on the slider 28c ｀ integrated with the plunger 28c into the notch 27d provided on the rotating member 27a, the driving force in the front-rear direction due to the protrusion and withdrawal of the plunger 28c is passed through the notch 27d. Is transmitted to the rotation member 27a, and the rotation member is rotated about the shaft portion 27c. When the plunger 28c (slider 28c２７) moves in and out as the solenoid 28a is turned on and off, the rotation member 27a is rotated about the shaft portion 27c, whereby the first through the pin 26d fitted in the elongated hole 27b. The door body 26a is opened and closed.

6 and 7 are perspective views showing a closed state and an open state of the first door opening / closing unit 29, respectively. A pin 26d provided on the first door 26 is a long hole 27b provided on the rotating member 27a. The first door body 26a is operated in the same manner as the rotation of the rotation member 27a when the rotation member 27a is rotated. There is almost no time lag between them, and quick opening and closing operations are achieved. In other words, the opening operation and the opening / closing operation of the first door 26 generally depend on the driving force from the solenoid, and there is no room for opening by a slow operation due to its own weight. Here, “substantially tightly fitting” does not necessarily mean a state in which the outer periphery of the pin and the inner wall of the elongated hole 27b are always in contact, but a state in which the pin is fitted in the elongated hole with some margin. Is included.
8 and 9 are perspective views showing the closed state and the open state of the second door opening / closing unit 44, respectively, and the second door 41 rotates in the front-rear direction around a rotation shaft 41b provided in the lower part. A second door main body 41a and a pin 41d protruding sideward from a side plate 41c protruding rearward from one side of the second door main body 41a are provided. The rotating shaft 41 b is pivotally supported by a pivotal support provided on the base member 50. The second drive source 43 is a solenoid 43a including a solenoid main body 43b, a plunger 43c protruding and retracting from the solenoid main body 43b in the front-rear direction, and a coil spring 43d that urges the plunger 43c in the protruding direction. The solenoid 43a is ON / OFF controlled by a control signal from a control means (not shown), and when turned ON, the plunger 43c is retracted against the coil spring 43d.

The second opening / closing mechanism 42 has a concave portion 42b in which the pin 41d is loosely fitted in a non-tight state at the front portion, and a rotating member 42a having a shaft portion 42c at the rear portion that is pivotably supported in the vertical direction. I have. The shaft portion 42 c is pivotally supported by a shaft support portion provided on the base member 50. By fitting a pin 43e provided on a slider 43c ｀ integrated with the plunger 43c into a notch 42d provided on the rotating member 42a, the driving force in the front-rear direction due to the protrusion and withdrawal of the plunger 43c is passed through the notch 42d. Is transmitted to the rotation member 42a, and the rotation member is rotated about the shaft portion 42c. The second door main body 41a is opened and closed via the pin 41d fitted in the recess 42b by rotating the rotating member 42a about the shaft portion 41b by the retracting operation of the plunger 43c accompanying the on / off of the solenoid 43a. It has a configuration.
Since the opening diameter of the recess 42b is significantly larger than the diameter of the pin 41d, the driving force when the rotating member 42a rotates is not immediately transmitted to the pin 41d in the recess 42b. There is a time lag between the rotating operation of the rotating member and the operation of the pin.
That is, when the solenoid body shown in FIG. 8 is turned off, the plunger is elastically biased in the protruding direction to lower the front portion of the rotating member 42a, whereby the pin 41d is pushed down by the upper inner wall 42b-1 of the recess 42b. The door body 41a is held in the closed position.

  When the solenoid body is turned on, the second door shifts from the closed state of FIG. 8 to the open state of FIG. 9, but even if the plunger 43c is retracted rearward to raise the front part of the rotating member 42a. The driving force in the door opening direction is not immediately transmitted to the pin 41d. That is, since there is a gap of a required width between the upper inner wall 42b-1 and the lower inner wall 42b-2 of the concave portion, the pin 41d is only relative to the pin 41d for the time required to pass through the gap. No driving force is transmitted, and the second door body 41a remains closed until the lower inner wall 42b-2 of the recess 42b contacts the pin 41d and presses it upward. Thereafter, after the pin 41d is initially pressed upward by the lower inner wall 42b-2 of the recess, the second door body 41a moves to the open position by its own weight. That is, the lower inner wall of the recess does not continue to push the pin until the second door body 41a shifts to the fully opened state shown in FIG. It only gives the door body an opportunity to open. The second door main body 41a reaches the fully opened position by its own weight after the pin 41d is pressed by the lower inner wall 42b-2 of the concave portion and the balance is lost. In this example, the complete open position of the second door body 41 is maintained by the pin 41d coming into contact with the upper inner wall 42b-1 of the recess as shown in FIG.

Therefore, the upward pivoting motion of the pivoting member 42a is not immediately transmitted to the pin 41d, but starts to be transmitted after a time lag corresponding to the time required for the pin 41d to relatively pass through the gap of the recess 42b. Then, immediately after the pin is pressed upward, the second door is opened by its own weight.
When the second door main body 41 is closed, the plunger 43c protrudes by the biasing force of the coil spring 43d by turning off the solenoid main body, contrary to the opened state. Move to the posture. In the state of FIG. 9, the pin 41d maintains a completely open posture by the upper inner wall of the recess. However, the upper inner wall 42b-1 of the recess causes the front part of the rotating member 42a to move to the lowered state of FIG. The pin 41d is pushed down to shift to a closed state.
Thus, according to the present invention, for example, when a big hit gaming state occurs with a short door opening time, the first door 26 is opened quickly for a short opening time and then quickly closed, while the door opening time is long. When the big hit gaming state occurs, the second door 41 can be opened with a slow motion and kept open for a long time, and can be closed with a slow motion even when closed. Therefore, the opening / closing operation patterns of the two doors 26 and 41 arranged adjacent to each other can be made different to give a contrasting impression, and an important change in the progress of the game can be brought about.

In particular, in the present invention, since two winning openings are arranged adjacent to each other, if the doors that open and close each winning opening are opened and closed at the same speed, the game contents may become monotonous and the interest may be reduced. In the present invention, the game content is changed by varying the time required for the opening and closing operations of each door according to the length of the opening time of each door.
In this example, the rotation shaft inside each of the first door 26 and the second door 41 uses one common rotation shaft 26b, but the other door is used for opening and closing the one door. A separate shaft member may be used to prevent the door from being opened and closed. That is, in FIG. 10, the first door 26 is supported by a dedicated inner turning shaft 26b, while the second door 41 is supported by a dedicated inner turning shaft 41e. For this reason, the other door is not operated by the opening / closing operation of one door, and the operation of each door can be made independent and separate.
The grand prize winning device of the present invention can construct a game board unit by being assembled to the game board. Further, by incorporating this game board unit into a pachinko gaming machine, it is possible to realize a door opening / closing operation that varies depending on the type of jackpot gaming state.
