Description

  The present invention relates to a variable display device installed on a game board.

  The variable display device installed on the game board of a pachinko machine displays a symbol that consists of multiple sets (usually three) of characters and figures on the central symbol display screen, and a predetermined prize opening (starting prize opening) ), The symbol is started to rotate, for example, in the vertical direction, and then, for the combination set in advance, the variation of this symbol is stopped based on the lottery result, and the symbol is stopped when stopped. When they are aligned in a set state, this is regarded as “winning”, for example, the door of a big winning opening (so-called “attacker”) is opened to make it easy to win the next hit ball, etc. The progress state of the game that occurs after the winning ball has entered is expressed through the above screen, and the game is produced to entertain the player.

  The present invention improves this variable display device, and also uses the variable display device as a temporary storage means for hitting a ball in accordance with the display of an image. The stored ball (injection ball) is, for example, a symbol display screen. In other words, the game is improved by actively guiding the start winning award to encourage the start of the game, thereby relevance between the two.

  As is well known, the variable display device generally displays three sets of symbols, and on the condition that the hit ball has entered the starting winning opening, this symbol is rotated and the like is changed, and then each symbol is stopped. When three sets of symbols come together in a predetermined combination, this is regarded as “winning”, and in conjunction with this, a specific winning device, for example, the aforementioned big winning opening etc., is opened, and a large amount is obtained within a short time. It is widely used as a way to add amusement to the game by expressing and producing the progress and the result of the game through images so that a prize ball can be released. For this reason, this device is also an indispensable component in current pachinko machines.

  In this way, the variable display device is usually installed at the center of the game board from the standpoint of producing effects. In order to further enhance the effect, the screen is further increased in size, and accordingly, a large area in the center portion of the game board is occupied by the variable display device. For this reason, there is a problem that the passing area of the hit ball is narrowed, and the change when the hit ball is dropped is scarce and simplified, and guidance to other winning devices is not performed smoothly.

Conventionally, as a solution to the problems associated with the increase in the size of the variable display device, or from the progress of the game displayed on the variable display device, the player's psychology that it is not a good idea to continue firing shots is solved. As a measure, a ball hitting entrance is formed in the variable display device, and a ball received by the ball is guided through a passage formed inside the variable display device, and this is positively applied to the start winning opening that generates the next hit condition. In order to eliminate the player's disadvantage, it is possible to change the fall of the hit ball, for example by guiding it to It has been broken. For example, Patent Documents 1 to 3 are given as such examples.
Japanese Patent Application Laid-Open No. 2002-315884. JP2003-290468A. JP 2004-135825 A.

Each of the above-mentioned patent documents relates to a variable display device that changes the design, although the names are different. An entrance that receives a hit ball in the device and a ball that is received through this entrance pass through the predetermined display. It is common to have a passage that leads to the direction of, and in addition to setting the downflow passage of the hit ball inside the device, it takes time to pass through this passage, and to the starting prize opening It is also common in the point of trying to cut the consecutive winnings.
However, the devices listed here form a new path, such as accepting a hit ball inside the device and guiding the received ball in a specific direction, for example, towards the starting prize opening as described above. , It does not give any further change, and no such expectation has been made.

  In view of the above-described conventional situation, the present invention adds a guidance and control function that leads to winning of the hit ball in addition to the original symbol display function for the variable display device installed in the center of the game board. In order to further increase the interest in the game by amplifying the probability of winning a prize, in addition to eliminating the simplification accompanying the decrease of the falling area on the game board It is in that.

  In particular, the present invention guides a hitting ball to a specific winning opening through forming a hitting ball passage in the variable display device so that it is advantageous to the player, and Temporarily storing the ball and releasing the ball under certain conditions to control the jump to the next prize opening or to change the jump condition advantageously. It is in.

  In order to achieve the above-described object, the present invention provides a variable display device having a display screen that displays a symbol in the center, and the left and right side frame portions of a frame that surrounds the screen that displays the symbol, or any one of them. Forming a hollow storage space that penetrates vertically in the side frame, forming an inlet at the upper part of the storage space, and forming an outlet at the lower part to form a storage chamber that can store a required number of jumping balls inside, Further, the outlet of the storage chamber is equipped with a discharge control device for storing the incoming ball by protruding a stopper piece when closed and retreating the stopper piece to release the stored ball from the outlet when opened. An object of the present invention is to provide a variable display device for a pachinko machine.

  The present invention utilizes the left and right side frame portions of the frame surrounding the symbol display screen in the variable display device, forms a hollow storage space inside the frame, and incorporates a release control device therein, thereby storing the sphere. The chamber is formed. Then, the inflow ball that enters through the entrance provided in the upper part of the storage space is stored in the storage chamber, and the storage ball is released in accordance with the release instruction to the release control device. This is because the variability is increased by controlling.

  That is, the present invention controls the release of the stored sphere to give a change in strength in the flow of the sphere, or selects the release timing, adjusts the number of released spheres, and further continuously or intermittently. In other words, it is possible to change the induction of the ball, for example, to the start winning opening which is held downstream after the release by creating various release modes by releasing the target.

The frame surrounding the symbol display screen constitutes the outer shape of the front surface of the variable display device, and is a part conventionally formed as a decoration. In the present invention, this frame, particularly the side frame, A storage space for storing the hit ball is formed inside, and a storage chamber is formed in the storage space.
As a result, a storage chamber provided in the winning device is formed in the variable display device itself. As a result, the variable display device itself is powerfully large without reducing the size of the variable display device or preventing the device from becoming large. The screen can be provided as it is.

The storage space is formed as a vertically long space along the side frame portion, and a storage chamber is formed in the storage space.
The storage chamber is formed by incorporating a stopper means for preventing the ball from flowing out, for example, a release control device provided with a stopper piece freely in and out at the lower part of the storage space. It is assumed that the hitting ball that enters through the inlet formed in the upper part of the storage space by the stopper piece is stored inside, and is released by an opening instruction to the release control device.

Moreover, the said storage chamber is stored in the state which arrange | positions the 1 thru | or several hit ball up and down by making it a vertically long space. As a result, at the time of discharge, the materials are discharged in order from the bottom.
When discharging a plurality of hit balls, that is, stored balls at the same time, the release speed, that is, the falling speed is different from the height position of each stored ball at the time of release. It will change individually and lead to a difference in induction after release.

On the other hand, the storage chamber is formed in the storage space by a release control device provided in the lower part. The storage chamber is spaced along the vertical length direction so that a plurality of stopper pieces can be moved freely. This includes partitioning the interior into a plurality of sections.
In this case, by opening the plurality of stopper pieces simultaneously or individually, it becomes possible to adjust the number of stored and discharged numbers, thereby realizing the discharge of different stored balls.

When the above-mentioned plurality of stopper pieces are provided, it is necessary to set the interval between the stopper pieces so that the pachinko balls are not bitten in between, but it is substantially set to the diameter of the pachinko balls or larger than that. This will prevent the biting of the ball. Of course, this does not prevent the space for storing two or more spheres between the stopper pieces, and in this case, an interval of two or more is provided.
Incorporation of a plurality of stopper pieces is selected according to the size of the storage chamber. At this time, the opening / closing operation of each stopper piece is arbitrarily selected based on the method of guiding the discharge ball.

The storage chamber in the variable display device of the present invention stores a hit ball that is fed through an inlet formed in the frame, and when the inlet is formed in the main body of the variable display, There are cases where the second upper entrance is opened on the upper surface portion of the upper frame portion.
The second entrance is opened to directly receive the hit ball falling from above the variable display device, and is usually formed on the upper surface of the upper frame portion and formed by hollowing the inside of the upper frame portion. The ball that has entered through the air will be introduced into the storage chamber.

  In the case of forming the second entrance, when the storage chambers are respectively formed in the left and right side frame portions of the frame body, the upper guideway is branched right and left immediately below the second entrance. The balls are distributed and guided to the respective storage chambers.

As described above, the storage chamber receives the hit ball through the flying port formed in the left and right side frame parts or the upper frame part of the frame body, and releases the storage ball by the opening operation of the release control device. This discharge is performed by retracting the stopper piece.
Then, in the present invention, the released storage balls are led to a guide shelf protruding forward along the lower edge of the symbol display screen of the variable display device, and rolled on the guide shelf, during which the front edge of the shelf is moved. It is dropped from the section, or is released again to the game area of the game board surface through a guide path formed on the upper surface of the shelf or inside the shelf.

The guide shelf can be arbitrarily selected in the direction of movement of the discharge storage ball by utilizing the width of the upper surface, and as described above, the difference in fall speed resulting from the difference in the height of the discharge position at the time of discharge is used. Some will be close, some will be far away and various rolling movements will be produced.
Then, in accordance with this rolling movement, the drop position from the guide shelf is changed, thereby increasing the gameability by making a difference in the winning rate to the next winning opening.

The guide shelf may have a dish-like upper surface of the shelf as one form so that the emitted ball can freely roll and fall from an arbitrary position. Also, a plurality of guide paths may be formed on the upper surface in advance, and a function of actively guiding such as leading to a specific winning opening, for example, a starting winning opening may be given by passing through the guide path in some cases.
In forming the guide path, in addition to being formed on the upper surface of the guide shelf, the guide shelf may be previously thickened to form a tunnel-shaped guide path inside. Further, the tunnel-shaped guide path and the groove-shaped guide path may be provided on the upper surface of the shelf so that they can be selectively guided to be changed.

  In addition, the guide shelf does not uniformly guide the balls released from the storage chamber, but also makes the player entertained by changing the rolling, and at the same time, when it finally falls, However, in practice, a specific route is established by, for example, forming the guide route, and this route is arbitrarily selected. As a result, the released storage ball is valued.

  By the way, the storage chamber formed in the side frame part of a frame body may open a vertical slit-shaped window along the length direction from confirming the number of balls to store. Of course, the opening of the window can be omitted by using a transparent or translucent plastic material for the side frame itself. In this case, since the release control device or the like is exposed, the confirmation of only the sphere is hindered, and the appearance is also impaired, so that care is required in manufacturing.

  According to the present invention, as is apparent from the above description, a storage chamber is formed in the side frame portion of the frame surrounding the symbol display screen of the variable display device, and a hitting ball is stored in this chamber and released in accordance with each situation. Therefore, the storage function provided in the conventional winning device is provided in the variable display device, and therefore, a ball storage chamber can be provided in the central portion of the game board together with the variable display device.

At the same time, since the present invention can release the stored ball in conjunction with the image expression through the display screen of the variable display device, it is possible to simultaneously execute the hitting ball processing and the image expression in conjunction with each other. It is possible to produce an integrated production with a sense of action.
And since the release of the storage ball can be selected by operating mechanically or artificially, for example, when a so-called reach state occurs, the change has stagnated after the hit occurs. When the game is executed, the game can be progressed.

  In addition, the variable display device is installed in the central part of the game board where the line of sight is most concentrated, and is equipped with a storage chamber for controlling the hitting ball in the interior thereof. There is an advantage that it can be directed to this storage room and a more powerful game can be enjoyed.

  In addition, since the present invention has a structure in which the hit ball is controlled and operated in the variable display device at the center of the game board in this way, the hit ball is processed in the left and right narrow spaces avoiding the conventional variable display device. Compared to, it is possible to secure a wide processing space, and there is an advantage that a large change can be given by the hit ball.

  Next, the best mode for carrying out the present invention will be described based on the embodiments shown in the accompanying drawings of the variable display device according to the present invention.

  FIG. 1 is a front view showing a state in which a variable display device according to the present invention is mounted on a game board, FIG. 2 is a schematic enlarged front view of the variable display device, and FIG. FIG. 4 is a schematic perspective view of the same.

  Reference numeral 1 in the drawing is a game board, 2 is a band attached to the front surface of the game board to form a game section 3, and a shot guiding path 4 for hitting a ball, 5 is a variable display device according to the present invention, 6 Is a start winning opening for creating an operation start state of the variable display device 5, 7 is a large winning opening having an opening / closing door 8 on the front surface, 9a, 9b, 9c are obstacle nails appropriately planted on the game board surface, It is a windmill.

  The game board 1 shown here is a game board used for a so-called separation-type pachinko machine. The variable display device 5 is assembled at a substantially central portion of the game unit 3 on the front surface of the game board. Above this variable display device, obstacle nails 9a that become ceiling nails are planted at a required interval so as to surround them, and obstacle nails 9b and 9c are arranged in rows from the left and right sides toward the lower central part, respectively. In addition, guide routes 11 and 12 are formed for guiding the hit ball toward the start winning opening 6 provided immediately below the center of the variable display device.

The variable display device 5 includes a liquid crystal screen 14 on the front surface of the display body 13, and is provided so as to project a frame 15 forward so as to surround the screen 14. A bowl-shaped mounting board 16 is extended from the outer peripheral surface of the opening of the frame 15, and the mounting board 16 is attached to the front surface of the game board 1 and assembled to the game board by fastening with a fixing tool such as a screw (not shown). Attached.
An upper frame portion 17 projects from the upper edge of the mounting substrate 16 over the entire length so as to cover the upper side of the screen 14, and a left frame 18 is formed on the left edge of the mounting substrate 16. Are formed in alignment with the front surface portion, and a storage space 19 is formed by providing a space penetrating vertically inside the left side frame portion 18.

  Here, the storage space 19 is formed as a rectangular tube-shaped space having a cross-sectional shape through which one pachinko sphere passes. The storage space 19 can sequentially pass through each sphere. The first release control device 21a is installed at a position near the outlet 20 at the lower end of the storage space 19, and the storage space 19 is formed in the storage chamber 22 by stopping and retaining the pachinko balls passing through the space. ing.

  Here, the release control device 21a is mainly formed of a solenoid. A stopper piece 23a is assembled to a plunger (not shown) of this solenoid, the stopper piece 23a is allowed to enter and exit freely in the storage space 19, and when the stopper piece protrudes inward, the passage of the sphere is stopped and stored. When retreated, the space, that is, the sphere stored in the room is discharged.

In the storage chamber 22 in this embodiment, as shown in the figure, second, third, and fourth release control devices 21b, 21c, and 21d are further provided above the release control device 21a, and each stopper piece 23b. , 23c, and 23d face each other freely so that the interior of the storage chamber 22 is partitioned into a plurality of rooms.
These stopper pieces discharge all the balls stored when they are all retracted, and sequentially release the stored balls in each partitioned room when they are sequentially retracted from the lower stopper pieces. Then, by selecting the stopper piece to be retracted, it is possible to discharge while selecting the number of discharges.
The number of the release control devices to be installed is arbitrarily selected in the design. However, the upper and lower stopper pieces should be installed so as to accommodate at least one pachinko ball with an interval not to bite the pachinko ball. become.

The plurality of release control devices increase the change of the game by making it possible to select the number of discharges of the storage balls. In this way, the storage chamber partitioned by the plurality of stopper pieces is at the lowest level. The protruding stopper piece substantially constitutes the bottom of the storage chamber.
On the other hand, the height of the bottom of the ball stopped by the stopper piece changes depending on the position of each stopper piece, resulting in a difference in height at the drop position at the time of discharge. A change occurs, and the rolling movement of the sphere after release changes.

On the other hand, the upper end of the storage space 19 serves as an inlet, and communicates with an air inlet 24 opened outward through a guide path 25. The entrance receives a hit ball that jumps in from the side of the frame body 15, and further communicates with an upper guide path 26 formed in the upper frame portion 17, and opens at the center of the upper surface of the upper frame portion 17. A hit ball that enters through the entrance 27 is received.
A hit ball that passes through the top nail 9a enters the second entrance 27, and an obstacle (not shown) is installed outside the left frame 18 in the entrance 24 that opens to the side. It will jump in by the guidance of the nail.

In the figure, 28 is a guide shelf provided so as to protrude forward along the lower edge of the frame 15, that is, the lower edge of the liquid crystal screen 14.
The guide shelf 28 is a device for rolling the storage ball discharged from the storage chamber 22 and creating a change during the movement to the next process. Here, the upper surface 29 is the lowest at the center of the front edge. It is formed in a half dish-shaped concave curved surface, and an entrance 30 is opened on the right side of the upper surface 29, and a tunnel-shaped guide path 31 formed in the inside of the shelf is formed in the front portion at the center of the front edge portion. It can be guided to the opening 32 to be opened. As a result, the stored sphere released from the left end of the upper surface 29 is guided by rolling the concave curved surface of the upper surface 29, and when the ball reaches the right entrance 30 and enters the right entrance, it rolls through the guide path 31. It can be guided to the outlet 32.

  The above-mentioned turnout opening 32 opens directly below the center of the lowest front edge of the upper surface 29 and faces the start winning opening 6 located below the turnout 32. Accordingly, the storage ball discharged from the outlet 20 of the storage chamber 22 rolls on the upper surface 29 and moves to the front edge portion according to the forward inclination, and varies from any position of the front edge portion depending on the strength of the roll. It will fall and be returned to the game board surface. At this time, a certain thing is guided to the nail row 9b and faces the start winning opening 6, and a certain thing comes off from the nail row 9b and falls as it is. And what reaches and falls to the center of the front edge falls from directly above the start winning opening 6, so that the jump rate to the winning opening 6 becomes high.

On the other hand, since the sphere that has reached the right entrance 30 falls vertically through the guide path 31 from the exit 32 toward the start winning opening 6 directly below, the entry rate is further increased.
The rolling of the guide shelf upper surface 29 varies depending on the state of discharge from the storage chamber 22. That is, when one storage ball is released when the lowermost (first) release control device 21a is opened, the falling speed is the slowest, and therefore the shortest roll is achieved. When a plurality of balls are released at the same time, the height of each ball is different, and at the same time, the upper one pushes out the lower one, so that the falling speed is increased and the ball rolls farther.
As a result, the position away from the guide shelf 28 changes due to the difference in rolling, and the distribution is made between the one that reaches the most advantageous start winning opening 6 and the one that does not.

  By the way, the plurality of release control devices 21a to 21d arranged in the step have different heights of the stopper pieces 23a to 23d in addition to selecting the number of discharges of the stored balls, so It was set to create a change in the falling speed resulting from the difference in height when the height changed and released. Therefore, by selecting the stopper piece to be opened, the rolling speed on the upper surface 29 of the guide shelf 28 can be variously changed by changing the falling speed of the discharge sphere.

  In the figure, 33 is a viewing window for confirmation formed vertically along the front wall of the storage chamber 22, and is used when the player confirms the stored ball during the game.

  FIG. 6 discloses a second embodiment of the present invention. This embodiment shows an example in which the shape of the upper surface 29 of the guide shelf 28 in the first embodiment is changed to change the rolling of the discharge sphere from the storage chamber 22. In the present embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  The guide shelf 34 in this embodiment is provided so as to protrude forward over the entire width along the lower edge of the liquid crystal screen 14 like the guide shelf 28 of the above embodiment. As shown in the figure, the upper surface 35 is formed in a mountain shape with a high central portion, and a groove-shaped guide path 36 having a downward slope toward the front is formed at the top of the center. All the spheres rolling on the upper surface 35 with a downward gradient roll to the front edge side and fall.

  Therefore, when the sphere released from the storage chamber 22 reaches the upper surface 35 of the guide shelf 34 by using the height of the discharge position as described above, some of the spheres on the left side 37a are based on the difference in the falling speed. In this case, some of them fall from the front edge and some enter the guide path 36 and fall down to the start winning opening 6 located immediately below the guide path 36. In addition, a certain thing passes over this guide path 36 and changes to the slope 37b on the right side, and similarly falls from its front edge along the forward and downward gradient, and is returned to the game board surface.

  Of course, the subsequent result of the falling ball in this case varies depending on the dropping position, and some of the balls reach the out-out ball port 38 and are discharged out of the machine, and some of them are nail rows 9b and 9c. To the start winning opening 6 or directly. Furthermore, it falls toward the open big winning opening 7 and wins.

  As described above, the present invention has been described based on the embodiments, but as is clear from the above-described configuration, the hit ball hitting the game board 1 and reaching the game unit 3 falls along the game board surface as it is and is installed in the center. When approaching the variable display device, not only the variable display device is avoided, but also an opportunity to jump into the entrance 24 or 27 provided therein is obtained. The hit ball that has entered here is then stored in the storage chamber 22 provided in the variable display device through the guide path.

The storage chamber 22 is configured by closing the discharge control device, that is, the solenoid 21a (or 21b, 21c, 21d), and the ball that has entered is stopped by the stopper piece 23a and stored.
The feature of the present invention is the storage chamber 22 and the discharge control device forming the storage chamber 22, that is, the solenoid 21a (21b, 21c, 21d), and the solenoid stopper piece 23a (23b, 23c, 23d) is stored. A storage chamber is formed by rushing into the space 19, thereby enabling the storage of the incoming ball. Then, by releasing this stopper piece, the stored balls are discharged at a time or individually or at a time, and moved to the next step, for example, as guided to the guide shelf 28 as described above. It is to be able to produce change.

  Next, the above relationship will be further described. The limit number that can be stored in the storage chamber 22 is set arbitrarily. The balls stored here create a state of staying as the game progresses, and thereafter, at one time by the player's operation or reaching a preset number of balls as described above, or Can be released in multiple batches. Therefore, conventionally, for example, when the number of remaining records of the ball that entered the start winning opening when the big hit state occurs exceeds the set number, the player temporarily stops the game by stopping the hitting of the ball, etc. Although the completion of the state is sometimes waited, in the present invention, such a suspended state can be effectively avoided because the effective ball can be kept waiting in the storage chamber immediately before the start winning opening.

In the present invention, the storage ball can be released at a time or by installing a plurality of release control devices in a divided manner. Thus, the rolling on the guide shelves 28 and 34 can be changed, and the winning rate for the start winning opening 6 can be changed.
In particular, if multiple solenoids are operated to change the number of emitted balls, the height of the release position of each ball will change, and the momentum of each drop will vary, so the rolling on the guide shelf will vary. In addition to being able to entertain the player, it is possible to further enhance the interest because the winning rate with respect to the start winning opening 6 is different.

  Note that the solenoid 21a, which is the release control device, and the other solenoids 21b, 21c, 21d can be opened and closed by the player's operation to release the stored ball, or the release conditions can be set in advance. It may be electrically controlled to release the storage balls, which are optionally selected by the practitioner.
