Description

  The present invention relates to a gaming machine such as a pachinko machine.

  Conventionally, in a pachinko machine that is an example of a gaming machine, a middle frame that supports various control devices such as a game board is hinged so that it can be opened in a single direction with respect to a machine frame that supports the main body. A front door for closing the front space (game area) of the board is hinged to the middle frame so as to be able to open one side. This front door is often opened and closed during games due to ball clogging occurring in the game area. However, when the front door is opened, for example, a game ball that has been clogged with a ball may spill and fall into the butterfly portion of the front door, causing a bite of the ball. Therefore, conventionally, a discharge hole through which a game ball can pass is formed in the hinge portion of the front door, and the game ball that has entered the hinge portion through the discharge hole is discharged outside the hinge portion. (For example, Patent Documents 1 and 2).

Further, when the “hit symbol” is confirmed and displayed, a so-called “hit state” occurs in which the door members of the big prize attackers 18a and 18b are intermittently opened a predetermined number of times. Therefore, the player performs “right-handed” to flow down the right-handed space SR and aims to win game balls to the big winning attackers 18a and 18b that are intermittently opened.

  In addition, after the jackpot state is finished, a so-called short-time state occurs in which the start winning combination 17 is frequently opened until the number of fixed symbols displayed on the special symbol display unit reaches a predetermined number. Therefore, the player continues “right-handed” until the short-time state ends, aiming to pass the game ball to the gate member 20 and to win the game ball to the start winning combination 17. Then, when the number of symbols fixed display reaches a predetermined number of times and the time-short state is finished, the game is returned to the above-described game in which the “right-handed” is stopped and the left-handed space SL is made to flow down.

(Ball removal structure at the hinged part of the front door)
Here, the ball extraction structure in the hinge part of the front door 4 which is the main part of the present invention will be described in detail.
FIG. 4 is an explanatory view showing the pachinko machine 1 from which the front door 4 and the game board 2 are removed from the front. FIG. 5 is an explanatory diagram showing the area A in FIG. 4 in an enlarged manner.

FIG. 9 is an explanatory view showing a horizontal cross section of the door hinge part 44, and the front door 4 is in an open posture with an open angle of 110 degrees.

  The middle frame 5 is a metal frame body assembled in a rectangular shape that is long in the vertical direction. The middle frame 5 is provided with a game board 2 in the upper part on the front side and a storage tray 8 and a handle 9 in the lower part on the front side. While each of the lower members 41 can be installed, various control devices can be installed on the rear surface side. The middle frame 5 is hinged to an upper butterfly portion 42 and a lower butterfly portion 43 provided at the upper left portion and the lower left portion on the front side of the machine frame 3. It can be opened as a shaft. Further, a door hinge part 44 for hinged to the lower side of the front door 4 is provided at a position facing the upper hinge part 42 in the vertical direction on the upper surface of the lower member 41. The front door 4 is hinged at the upper part to the upper butterfly part 42 and at the lower part to the door butterfly part 44, and can be opened to the middle frame 5 with the left edge as an axis. Note that the front edge of the left frame portion of the middle frame 5 (particularly located at the rear of the front door 4) is bent to the left (outside) as shown in FIG. The front surface of the bent portion is a facing surface 45 that faces the rear surface of the left edge of the front door 4 in the closed position.

  The door buttering portion 44 has a flat portion 46 that is flat in the horizontal direction, and a shaft hole (not shown) provided on the bottom surface of the front door 4 at a position near the front of the flat portion 46. A shaft portion 47 that can be inserted into is projected. Further, further forward of the shaft portion 47, when the opening angle of the front door 4 reaches a specific angle (110 degrees in this case), it comes into contact with a predetermined portion of the front door 4 and the front door 4 is further rotated in the opening direction. A restricting rib 48 for restricting the movement is provided. Further, the rear end edge of the flat portion 46 abuts on the facing surface 45, and the guide plate 49 is attached to the facing surface 45 in such a manner that the rear end edge is erected upward along the facing surface 45. It has been.

  The guide plate 49 is formed by bending the upper end portion of the metal plate forward by approximately 90 degrees, and the leading edge of the bent portion 49a is formed in a curved shape that gradually protrudes forward toward the left side (outside). Yes. Further, the vertical length of the guide plate 49 (the length from the flat portion 46 to the bent portion 49a) is about half of one game ball (for example, 6 mm). The outer surface of the guide plate 49 is covered with an outer rib 51 protruding forward from the left end portion of the facing surface 45.

  On the other hand, the left side surface of the front door 4 is substantially flush with the outer surface rib 51 in the closed posture, and is between the rear edge 4a of the left side surface of the front door 4 and the front surface of the outer surface rib 51 of the middle frame 5. Are very close. In addition, on the rear surface of the front door 4, a protruding portion 52 that protrudes rearward is provided at a position that is positioned in front of the bent portion 49 a of the guide wall 49 in the closed posture, and a reinforcing plate 53 is provided on the protruding portion 52. Is attached, and the rear end edge of the reinforcing plate 53 and the front surface of the guide plate 49 are also very close to each other. Furthermore, a ball scoop portion 54 (shown in FIG. 1) that is recessed to the right and that opens to the front side of the front door 4 is provided at the lower end portion of the left side surface of the front door 4 (position near the hinged portion). ing. The ball scoop portion 54 has a vertical height and a horizontal width in which a game ball can enter, and its bottom surface is gradually inclined downward toward the left side (outside), and the thickness to the bottom surface of the front door 4 is increased. It is formed into a thin tapered shape.

Then, the movement of the door hinge part 44 when opening and closing the front door 4 will be described. When the front door 4 (shown in FIG. 7) in the closed position is rotated in the opening direction, the left side surface of the front door 4 The rear end edge 4a moves across the front of the guide plate 49 from left to right (FIG. 8). During this movement, the longitudinal distance between the rear edge 4a and the leading edge of the bent portion 49a of the guide plate 49 is not more than the diameter of one game ball (strictly, the radius of the game ball). Yes. Further, when the opening angle of the front door 4 is further rotated in the opening direction until the rear edge 4a faces forward, the left side surface (including the ball scooping portion 54) and the front surface of the front door 4 are guided. The posture is such that it faces the plate 49 side (FIG. 9). At this time, the gap 55 between the front door 4 and the leading edge of the bent portion 49a of the guide plate 49 is at least a diameter of one game ball (in this embodiment, 11 mm or more), and the left side is pachinko. The gap 55 is opened to the outside of the machine 1 and functions as a discharge path for discharging the game ball that has entered the door buttering portion 44 to the outside of the door hinge portion 44.
Note that when the front door 4 is rotated in the closing direction, the rear end edge portion 4a of the left side surface of the front door 4 naturally follows the movement locus when rotating in the opening direction.

Here, the ball removing action at the door butterfly 44 will be described.
For example, when a ball clogging occurs in the game area 16, it is necessary to open the front door 4 to eliminate the ball clogging. Therefore, when the front door 4 is opened, a game ball may spill from the game area 16 and may enter the flat part 46 of the door hinge part 44. At this time, when the opening angle of the front door 4 is small, for example, when the rear end edge 4a of the left side surface of the front door 4 is positioned in front of the guide plate 49, the rear end edge 4a faces the middle frame 5 side. Due to the proximity, the game ball is prevented from entering the flat portion 46. On the other hand, if the opening angle of the front door 4 is large, for example, the front door 4 is opened to the maximum, the game ball enters the gap 55 between the front door 4 and the guide plate 49, that is, on the flat portion 46. However, the game ball that has jumped into the gap 55 is discharged out of the pachinko machine 1 through the gap 55 as it is. Even if the front door 4 is rotated in the closing direction, the rear end edge 4a is rotated close to the middle frame 5 until the distance is equal to or less than the diameter of the game ball, even if the front door 4 is stopped. Therefore, the game ball that has been stopped is pushed out to the left side surface of the front door 4, and moves to the left (outside of the pachinko machine 1) in the gap 55 while being guided by the leading edge of the bent portion 49a. Finally, it is discharged out of the pachinko machine 1.

  However, even when trying to discharge outside the pachinko machine 1 (to the left of the pachinko machine 1), a ball lending machine (not shown) is generally installed on the left side of the pachinko machine 1, so the front door 4 It is also possible to cause a ball bite between the left side and the ball lending machine. However, according to the pachinko machine 1 of the above embodiment, since the ball scoop portion 54 is provided at the lower end portion of the left side surface of the front door 4, it is likely to be sandwiched between the left side surface of the front door 4 and the ball lending machine. The game ball that has entered enters the ball scoop portion 54. And since the ball lending machine is installed, it moves to the front side of the pachinko machine 1 while being held in the ball scoop part 54 without spilling from the ball scoop part 54 to the left, and the front door 4 Is discharged to the front side of the pachinko machine 1.

(Effects of the pachinko machine of this embodiment)
In the pachinko machine 1 having the above-described configuration, when the front door 4 is opened to a predetermined opening angle or more, a game ball can pass between the left side surface of the front door 4 and the middle frame 5 side, and A gap 55 is formed so that the left side opens to the outside of the pachinko machine 1. In addition, when the front door 4 is rotated on the closed posture side below a predetermined opening angle, the distance in the front-rear direction between the rear edge 4a and the middle frame 5 side is less than the diameter of one game ball. The rear end edge portion 4a is configured to be close to the middle frame 5 side. Therefore, even if a game ball enters the gap 55 between the front door 4 and the middle frame 5 side, it is only necessary to close the opened front door 4 (strictly speaking, by turning in the closing direction). The game ball is pushed out to the left side of the front door 4 and the game ball is discharged out of the pachinko machine 1 through the gap 55. Therefore, it is very easy to remove the ball from the door buttering portion 44, and it is not necessary to open a discharge hole in the door buttering portion 44 as in the prior art, so that the crime prevention performance is not impaired.

In addition, a ball scooping portion 54 that is recessed to the right and opened to the front side of the front door 4 at the lower left side portion of the front door 4 (in the vicinity of the hinged portion) and into which a game ball can enter is provided. The game ball that is about to be discharged from the gap 55 is inserted into the ball scooping portion 54. Therefore, the game ball to be discharged out of the pachinko machine 1 is sandwiched between the ball lending machine adjacent to the pachinko machine 1, and as a result, the ball between the front door 4 and the ball lending machine. It is possible to prevent a situation in which biting occurs.
Further, since the bottom surface of the ball scooping portion 54 is gradually inclined downward toward the outside, and the thickness up to the bottom surface of the front door is formed in a tapered shape, the game ball can be smoothly moved into the ball scooping portion 54. Thus, it is possible to more reliably prevent the ball biting between the front door 4 and the ball lending machine.

  In addition, a guide plate 49 having a height about the radius of the game ball is erected on the rear end edge of the flat portion 46 of the door buttering portion 44 along the facing surface 45 of the middle frame 5. A bent portion 49a is provided at the upper end, and the leading edge of the bent portion 49a is formed in a curved shape that gradually protrudes forward toward the left side. Therefore, when the front door 4 rotates, when the rear end edge 4a passes right and left in front of the guide plate 49, the distance between the rear end edge 4a and the middle frame 5 side is equal to or less than the diameter of the game ball. The ball can be prevented from being bitten further, and the game ball in the gap 55 can be smoothly moved outside the pachinko machine 1 along the front edge of the bent portion 49a (front surface of the pachinko machine 1). Side).

(Modifications of the present invention)
Note that the configuration related to the gaming machine of the present invention is not limited to the above-described embodiment, and the configuration related to the ball pulling structure in the door hinge part as well as the configuration of the entire gaming machine is the gist of the present invention. As long as it does not deviate from this, it can change suitably as needed.

For example, in the above embodiment, the rear edge of the front door and the middle frame are opposed to each other, but the rear edge of the front door may be opposed to the machine frame. “Middle frame side” is a subordinate concept of “machine frame side”.
In the above embodiment, the upper side of the front door and the upper side of the middle frame are hinged to the same upper butterfly part, but there is no problem even if they are hinged to different butterfly parts. In addition, the design of the front door and the middle frame can be appropriately changed as to whether the left and right side edges are attached as a shaft so that they can be opened in a single direction.

Further, to what degree the front door is opened, a gap is formed that allows the game ball to pass and the left side to open outside the gaming machine (ie, how many times the predetermined opening angle is set) Can be changed as appropriate.
Needless to say, the design of the presence / absence and size of the guide plate and the shape of the front surface as well as the presence / absence and size of the recess and the shape of the recess can be changed.

In addition, in the above embodiment, a pachinko machine that is an example of a gaming machine has been described. However, the present invention is naturally applicable to other gaming machines such as a sealed pachinko machine.
