DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine having means for preventing ball clogging in a member arranged in a game area, and more particularly, to a pachinko machine in which a game ball is sandwiched between a special winning opening and a pachinko machine front glass. The present invention relates to a pachinko machine having a ball bite preventing means for preventing biting (biting).

[0002]

2. Description of the Related Art Based on the satisfaction of a predetermined condition,
As a pachinko machine in which the special winning state of the variable winning device of the variable winning device provided on the game board is continuously opened for a predetermined time and a special gaming state advantageous to the player is generated, a plurality of types of symbols are displayed or changed. There is a device provided with a symbol display device for performing stop display.

[0003] This symbol display device is generally arranged at a substantially central portion of a game board, and a plurality of symbols are changed on a display unit arranged in a plurality of rows based on winning of a game ball to a starting winning opening. After a predetermined time, the symbols selected from the symbols are stopped and displayed on the respective display units. When the combination of symbols stopped and displayed is a combination of predetermined specific symbols (when the above-described predetermined conditions are satisfied), the special winning opening provided on the game board surface is set to a predetermined size. , The player can obtain many prize balls in a short time, and a special game state (also called a big hit state) advantageous to the player occurs.

[0004] The special winning opening is provided below the symbol display device, and is provided with a door that opens and closes by the operation of a solenoid or the like. When the opening is opened, the door is rotated forward by a predetermined angle to flow down on the game board surface. It works by catching incoming game balls with open doors and guiding them into the special winning opening.

In a pachinko machine having such a configuration, a big hit state is generated by a symbol displayed on a symbol display device, so that the interest of the player is concentrated on the displayed symbol. Therefore, in order to further increase the willingness to play the game, it is necessary to display the symbol large, that is, to further increase the size of the symbol display device. However, when the size of the symbol display device is increased, the game area (downflow area) of the game ball on the game board is reduced by that amount, which causes a problem that the original playability of the pachinko machine is reduced. Also, since the game balls flowing down the game board surface flow down the symbol display device, when the symbol display device is enlarged, the starting winning opening and the large winning opening located substantially at the center below the symbol display device are provided. It becomes difficult to make the game ball flow down in the direction. Therefore, in order to allow the game balls to enter the big winning opening to the same extent as before when the big winning opening is opened due to the big hit state, the starting winning opening and the big winning opening are set according to the size of the symbol display device. It is necessary that the position be as low as possible below the game board.

However, the size of the game area is constant,
Since the shape is also formed in a substantially circular shape, the positions of the starting winning opening and the large winning opening to be installed below are limited, and the degree of freedom is small. Therefore, in order to make it easier for the game ball to win the big winning opening, a means for increasing the width of the door of the big winning opening can be considered. In addition, when the starting winning opening is located as much as possible below the game board, it is necessary to reduce the vertical width of the large winning opening located below the starting winning opening. However, when the vertical width of the winning opening door is reduced, a gap between the door and the front glass when the door is opened becomes large, and a game ball is easily trapped in the gap (a so-called ball bite). (Prone to occur). Due to the occurrence of this ball biting, the door of the special winning opening is not closed (it remains open), causing serious damage to the hole side.

Therefore, in order to prevent such a problem caused by the occurrence of the ball biting, the ball biting is performed on the front side of the special winning opening, that is, a gap formed between the door and the front glass when the large winning opening door is opened. A ball game machine provided with a (jamming) prevention member has been proposed (JP-A-11-206971).

[0008]

By the way, in the conventional pachinko machine having such a configuration, it is effective to prevent a game ball from being caught in a gap between a door of a special winning opening and a front glass. However, it has the following drawbacks. That is, since the pinching prevention member for the game ball is disposed at a position substantially overlapping the large winning opening in the front-rear direction of the game board surface (a position covering the entire large winning opening), the door of the large winning opening is When opened, an anti-jamming member overlaps the opening, and the player controls the movement of the game ball in the vicinity of the special winning opening and the movement of the game ball winning in the grand winning opening via the anti-jamming member. (The other side of the prevention member), or must be viewed from above the pinch prevention member, making it difficult to confirm the whereabouts of the winning ball or determine the drop position of the winning ball. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and facilitates the movement of a game ball that wins in the special winning opening when the door of the special winning opening is opened, or a game ball in the special winning opening. It is an object of the present invention to provide a pachinko machine having a ball biting prevention member that can be recognized, and a pachinko machine having a ball biting prevention member capable of improving the assembly workability of the pachinko machine.

[0010]

In order to solve the above-mentioned problems, the invention according to claim 1 is characterized in that a large winning opening door provided on a game board is provided with a predetermined winning condition based on satisfaction of a predetermined condition. In a pachinko machine in which a special game state advantageous to the player occurs at least once, the pachinko machine is continuously opened for a period of time, a ball biting prevention member is provided in front of the special winning opening, and a door portion of the special winning opening is provided. The ball bite prevention member disposed on the front surface of the ball bite prevention member is installed at a position where the position of the upper end portion of the ball bite prevention member is approximately the same height as the position of the upper end portion of the door when the big winning opening door is opened. It is characterized by that.

[0011] By providing a ball biting prevention member on the front side of the special winning opening, the gap between the door and the front glass formed when the large winning opening door is opened can be reduced, and when the door is opened or the door is opened and closed, A game ball is prevented from being caught in a gap between a door and a front glass, and stoppage of the opening / closing operation of the door is reduced.
Further, when the door of the special winning opening is opened, the opening and the ball biting prevention member do not overlap with each other, that is, the ball biting prevention member is installed at a position where the ball biting prevention member does not cover the opening when viewed from the player. This makes it possible for the player to easily recognize the game ball that wins the special winning opening.

According to a second aspect of the present invention, in the first aspect of the present invention, the shape of the ball biting prevention member is a thin plate, and its height gradually increases from the center toward both ends. Is characterized by an arcuate shape in which the height is higher. The game area formed on the game board has a substantially circular shape. By setting the shape of the ball biting prevention member to an arcuate shape substantially along the outer periphery of the game area, a limited game area can be used effectively.

According to a third aspect of the present invention, in the first or second aspect, the ball biting prevention member is
It is provided in the projection surface of the special winning opening mounting base. Thereby, in the manufacturing process of the pachinko machine, when the mounting base member having the winning opening is mounted on the game board, the ball biting preventing member does not hinder the mounting operation and prevents a reduction in work efficiency.

The special winning opening door 10a provided in the special winning opening 10 opens and closes. FIG. 2 shows a state in which the special winning opening door 10a performs an opening operation and the special winning opening 10 is opened. Winning device 2
1 is a special winning opening mounting base (hereinafter referred to as mounting base)
22, a winning opening door 10a, and a driving unit 23 for driving the opening and closing operation of the winning opening door 10a.

The mounting base 22 is made of a thin plate made of a synthetic resin material having excellent impact resistance.
And is screwed to the lower area of the game area 3 (the lower area of the variable winning device 5) via the screw hole 24.
Since the attachment base 22 has a thin plate shape, it does not protrude from the game area surface even when attached to the game area 3 and does not obstruct the flow of the game ball. In addition, since the shape of the lower surface of the mounting base 22 is substantially the same as the lower shape (arc shape) of the game area 3, the mounting base 22 can be efficiently mounted even in a narrow area. A mounting member 25 for mounting the ball biting prevention member 15 is provided near the left and right ends of the front surface of the mounting base 22. The upper surface of the attachment member 25 is formed so as to be inclined toward the out opening 12 and the special winning opening 10, and has a function of guiding the flowing game balls toward the out opening 12 and the special winning opening 10.

The opening of the special winning opening 10 is attached to the mounting base 22.
Is formed by notching a part of a rectangular shape, and is provided at the upper center of the mounting base 22. Grand Prize Win Door 1
Reference numeral 0a denotes a door that covers the special winning opening 10 when the door is closed and prevents game balls from winning into the special winning opening 10, and has a horizontally long thin plate shape and a substantially rectangular shape. A pair of supporting shafts are provided at both ends in the longitudinal direction of the special winning opening door 10a, and are pivotally supported in convex portions 26 provided on both sides of the opening of the mounting base 22. As a result, the special winning opening door 10a opens and closes around the pivotally supported longitudinal door side. When the door is opened, the door is opened to the front side, the door surface is directed upward, and the flowing game balls are received and guided into the special winning opening 10. Further, in order to surely guide the game balls received by the open door into the special winning opening 10, the open special winning opening door 10a is opened so as to have a predetermined inclination angle toward the special winning opening 10. .

The driving unit 23 is provided on the back of the mounting base 22,
That is, when the winning device 21 is attached to the game board 1, it is disposed so as to be located on the back side of the game board 1. The driving unit 2
Numeral 3 generally comprises a solenoid 27 for controlling the opening and closing operation of the special winning opening door 10a, and a control board 28 for transmitting an electric signal to the solenoid 27 and controlling the operation of the solenoid 27.

The ball biting prevention member 15 disposed on the front side of the special winning opening 10 (the special winning opening door 10a) so as to face the mounting base 22 is fixed to the mounting member 25 by screws. Further, the ball biting prevention member 15 has a substantially arcuate shape, and its center portion is the lowest, and its height gradually increases substantially symmetrically from the center portion toward both ends. It is fixed. Since the game area 3 formed on the game board 1 has a substantially circular shape, the shape of the ball biting prevention member 15 is formed into an arcuate shape substantially along the outer shape of the game area 3 (substantially the same as the outer shape). This makes it possible to effectively use the limited game area below the variable display device 5 where the special winning opening 10 is arranged. In addition, ball biting prevention member 1
5 is made of a thin synthetic resin material having excellent impact resistance, so that it is possible to recognize a game ball flowing down on the back side of the ball bite prevention member 15. The ball biting prevention member 1
5 is not limited to a transparent material, and may have a predetermined pattern, color, or the like. By giving patterns, colors, and the like, the visual interest of the player can be enhanced.

The ball biting prevention member 15 is mounted so as to be located within the projection plane of the mounting base 22. That is, the lateral width of the ball biting prevention member 15 (the width in the left-right direction in FIG. 1).
Is smaller than the horizontal width of the mounting base 22, and the height (the vertical width in FIG. 1) of the ball biting prevention member 15 is formed lower than the height (the vertical width) of the mounting base 22. The winning device 21 has a screw hole 24 formed in the mounting base 22.
Is screwed into the game area 3 via the ball. Therefore, by making the shape of the ball biting prevention member 15 smaller than the shape of the mounting base 22, the ball biting is performed when the winning device 21 is mounted in the manufacturing process of the pachinko machine. The prevention member 15 prevents the installation work from becoming an obstacle. The means for attaching the prize device 21 to the game board 1 is not limited to screwing, and the game device 1 is engaged with the game board 1 by a claw provided on the prize device 21 without using screws or screws or screws. It may be the one that causes it.

The width of the ball biting prevention member 15 (width in the left-right direction in FIG. 1) is smaller than the width of the variable display device 5 (the width including the decorative frame 14 covering the symbol display 6). . In order to prevent a game ball from being caught (ball biting) between the door and the front glass accompanying the opening and closing operation of the special winning opening door 10a, ball biting is prevented more than the minimum required width of the special winning opening door 10a. While setting the width of the member 15 large,
The width is set smaller than the width of the variable display device 5 on which the big hit determination symbol is displayed. By setting the ball bite prevention member 15 to such a size, the size of the variable display device 5, which most greatly affects the player's willingness to play, can be designed to be larger. Thereby, it becomes possible to concentrate the interest of the player on the variable display device 5, and
By increasing the size of the variable display device 5, the lower game area of the variable display device 5, which is limited, can be effectively used.

The ball biting prevention member 15 is installed at a position where the opening portion of the special winning opening 10 is not covered when the large winning opening 10 is opened by the opening operation of the special winning opening door 10a.
That is, when the special winning opening door 10a is opened, the long side 10p of the special winning opening door 10a approaching the ball bite preventing member 15 side is set.
Height (position) and the height (position) of the upper end 15p of the ball bite prevention member 15 disposed in front of the special winning opening 10 (large winning opening door 10a) are substantially the same height (position). It is installed so that it becomes. As a result, the player receives the special winning opening door 10a.
The position of the game ball flowing down or the movement of the game ball winning in the special winning opening 10 can be easily and accurately recognized. Further, the gap between the door and the front glass, which is generated when the special winning opening door 10a is opened, is surely reduced.
The game ball can be prevented from being caught in the gap between the door and the front glass at the time of opening the opening or the opening and closing operation of the special winning opening door 10a, and the trouble of stopping the opening and closing operation of the special winning opening door 10a can be reduced.

The ball biting prevention member 1 having a thin plate shape
The thickness of No. 5 is changed according to the vertical width (height) of the special winning opening 10 (large winning opening door 10a) of the pachinko machine. That is, when the height of the special winning opening door 10a is low, a gap generated between the special winning opening door 10a and the front glass at the time of opening the door increases, so that the thickness of the door is reduced by that much in order to reduce the gap. It is set thick, and conversely, the big winning opening door 10a
When the height of the door is high, the thickness of the door is set thinner accordingly. When the width of the special winning opening 10 is increased by appropriately changing the plate thickness of the ball bite preventing member 15 in this manner (in this case, if the entire area of the special winning opening 10 is constant, the special winning opening is correspondingly increased). (The height of the game ball 10 becomes smaller). The player can be guided into the special winning opening 10 with a probability, and a large number of prize balls can be given to the player when a big hit occurs. In the above-described embodiment, the case where the specific symbol is stopped and displayed is shown as a condition for opening the special winning opening. However, the present invention is not limited to this. May be conditional on the case of winning.

[0030]

According to the pachinko machine of the present invention, since the ball winning prevention member is provided on the front side of the special winning opening, the gap between the door and the front glass which occurs when the special winning opening door is opened can be reduced. This prevents game balls from being caught in the gap between the door and the front glass when the door is opened or when the door is opened or closed (so-called ball biting), and prevents the door from stopping the opening and closing operation. It is possible to prevent the damage on the pachinko hall side. Also, the player can concentrate on the game. When the winning opening door opens,
Since the opening of the special winning opening is not overlapped with the ball biting prevention member as viewed from the player, that is, the opening is not covered or covered by the ball biting preventing member, the player wins the large winning opening. It is possible to easily and accurately recognize the game ball to play, and to play the game in a big hit state more concentratedly.

Since the shape of the ball biting prevention member is substantially the same as the outer peripheral shape of the game area, the winning device (large winning opening) is provided even if the variable display device is further enlarged. The limited game area below the variable display device can be effectively used.

Further, the size of the ball bite preventing member is formed smaller than the size of the special winning opening mounting base, and the ball bite preventing member is mounted on the projection surface of the large winning opening mounting base. In the manufacturing process, when the special winning opening mounting base is mounted on the game board, the ball biting prevention member does not hinder the mounting operation, and the working efficiency can be improved. Further, even in the state of the winning device alone before assembling the pachinko machine, it is possible to prevent the ball biting prevention member from being damaged.
