Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a variable winning device in which a game ball wins in a ball game machine such as a pachinko gaming machine that uses a game ball to play, and more particularly to a variable winning device that allows a door plate to be opened manually.
[0002]
[Prior art]
A conventional gaming machine will be described by taking a pachinko machine as a typical example as an example.
Conventional pachinko machines have a game area on the surface of the game board, and in this game area, obstacle nails that change the flow direction of the game ball are planted, and a winning opening for the game ball to win is arranged. It is. Then, when a game ball is launched into the game area and the direction of the game ball flowing down by a obstacle nail or the like wins the prize opening, a predetermined number of game balls are discharged as a prize ball by the prize ball discharge device. .
The winning awards include a normal award and a variable award (a variable award device) provided separately from the award.
[0003]
The variable winning opening has a larger opening than a normal winning opening, and a large number of game balls can be won. A door plate that closes the opening is provided in front of the opening so as to be tiltable forward. This door plate has a first state (corresponding to a closed state) in which the opening is closed and the game ball cannot be received in the variable prize opening, and a second state (open) in which the door plate is tilted forward to accept the game ball. Equivalent to the state).
And this door board is arrange | positioned so that it may become substantially the same plane as the surface of a game board so that the movement of the game ball which may flow down may not be prevented in the 1st state which block | closed the opening part. Then, by tilting forward, it is possible to accept a game ball flowing down from above. Therefore, in the second state in which the door plate is tilted, a large number of game balls can be easily won.
[0004]
This variable winning opening is controlled to open and close when, for example, it is a big win in a variable display game performed by a special symbol display device arranged at the approximate center in the game area. In other words, at the time of a big hit, the door plate is intermittently tilted forward so that a variable winning opening can be won, so that a player can easily obtain many prize balls. For example, a predetermined number (for example, 10) of game balls is counted as one cycle, and the door plate is tilted forward with a predetermined pause time between each cycle.
[0005]
[Problems to be solved by the invention]
By the way, in a gaming machine using such game balls, a maximum of 100 game balls are continuously fired into the game area per minute. Therefore, when a plurality of game balls flow down in a continuous state, the game balls may be clogged in a flow path formed by obstacle nails or the like. In addition, when game balls win continuously, a large amount of game balls (prize balls) are discharged from the prize ball discharge device, and the game balls may be clogged in the prize ball discharge device. .
In such a case, the game store clerk removes the game balls that are jammed, and the door plate is artificially tilted forward (ie, opened) to compensate for the player's disadvantage due to the game balls being clogged. A service is provided in which an appropriate number of game balls are picked up with a finger and awarded to a winning opening.
[0006]
In addition, even when a variable display game is a big hit just before the closing of a game store, in order to guarantee a large amount of prize balls due to this jackpot, an appropriate number of game balls are awarded to the winning opening. .
[0007]
However, it is troublesome to pick a plurality of game balls with a finger and win a regular winning opening many times.
There is also a variable prize winning device in which a rib also used as a weight is provided on the front surface of the door plate, and this rib is used for opening and closing the door plate, but in this case, the door plate can be easily opened, so multiple games It is easy to win the ball by hand, but the variable winning device without ribs is arranged so that the door plate is almost flush with the surface of the game board, so it is difficult to open (tilt forward) manually. Met.
Further, the variable winning device having the ribs may be damaged by the collision of the game balls. In other words, game balls are generally made of iron and have a certain amount of weight. Therefore, if a large number of game balls collide with the ribs over a long period of time, the ribs may be damaged by the impact from the game balls. was there.
[0008]
In addition, the apparatus having the ribs on the door plate has a problem that the aesthetics of the apparatus are impaired by the ribs. Further, since the rib changes the flow path of the game ball, the layout considering the flow path is limited when the winning opening is provided below the variable winning device.
[0009]

And when a solenoid demagnetizes, it will be urged | biased by a spring and will return to a 1st state. As described above, the door plate 15 can be controlled to be opened and closed by a solenoid or a spring.
[0038]
The case 141 is disposed on the back surface of the mounting base plate 16 so as to cover the opening 161 from the rear. As shown in FIG. 6, a concave chamber 142 communicating with the opening 161 is formed by the case 141. The concave chamber 142 is an empty space in which a game ball won in the special variation winning device 14 enters, and the concave chamber 142 is used to determine whether or not the winning possible state for the special variation device 14 is continued until the next round. A continuous winning switch, a count switch for counting the total number of game balls won in the special winning device, and the like are provided.
[0039]
A blindfold plate 143 is erected downward on the upper inner wall in the concave chamber 142. The blind plate 143 is provided at a position adjacent to the back surface of the door plate 15 in the first state so that the concave chamber 142 cannot be seen from the gap CL.Clearance CL Block from the concave chamber 142 sideYes. At least the front surface of the blindfold plate 143 has a dark color such as black or gray or the same color as the door plate 15 or the mounting base plate 16. As a result, the color of the gap CL is the same as that of the dark color or the door plate 15 or the mounting base plate 16, and the gap CL becomes inconspicuous from the player. Therefore, it is possible to improve the aesthetic appearance of the special variation winning device 14.
[0040]
When the door plate 15 is opened forward by a manual operation by a store clerk or the like of a game store, after opening the glass frame 2 ', as shown in FIG. 6, the pin of the ball removal pin 50 as an opening operation member The front end 53 of the part 52 is inserted between the upper end surface of the door plate 15 and the opening 161, that is, in the gap CL serving as an insertion part. At this time, as shown by a solid line in the figure, by tilting the pin portion 52 downward, the tip 53 of the pin portion 52 enters the recessed portion 151, and both are caught.
[0041]
From this state, the grip 52 (FIG. 3) of the ball removal pin 50 isFIG.As shown by the arrows in FIG. 4, when the rear end 53 is moved toward the game board 3 side, the tip 53 rotates forward, that is, toward the front, with the edge of the opening 161 indicated by symbol A in FIG. At this time, the tip 53 of the pin portion 52 is in a state of being hooked with the recess 151 of the door plate 15, so that the door plate 15 is tilted forward by its own rotation, as indicated by a dotted line in FIG.
Then, in the state of this dotted line, a fingertip is hooked on the upper end surface of the door plate 15, the door plate 15 is further tilted forward, and a game ball is inserted.
[0042]
As described above, in this embodiment, the opening operation member is disposed on the back surface side of the upper end portion of the door plate 15 which is the outer peripheral edge portion of the door plate 15 above the shaft portion 152 which is the axially attached portion of the door plate 15. As shown in FIG. 4, a recess 151 is provided to which the tip 53 of the pin portion 52 of the ball removal pin 50 is engaged, and between the upper end of the door plate 15 and the opening 161 of the mounting base plate 16, the tip 53 of the pin 52. Is provided with a gap CL having a vertical width that can be inserted from the front, and the hollow portion 151 and the gap CL are used as insertion empty portions, so that the tip 53 of the pin portion 52 can be easily locked to the door plate 15. When the door plate 15 is manually tilted, the operation can be facilitated.
[0043]
In addition, if the above-mentioned hollow part 151 and the clearance gap CL are above the axial attachment part of the axial part 152 used as the rotation center of the door board 15, it will also be on the outer peripheral part of door plates, such as a right side part or a left side part. It can be provided similarly.
[0044]
As the operation member for tilting the door plate 15, in addition to the ball removal pin 50, any member having a thin tip such as a mechanical pencil or a flat-blade screwdriver or a thin plate member can be used.
However, as described above, the ball removing pin 50 is normally used for other purposes and is carried by a store clerk of the game shop. By using a member, a dedicated operation member becomes unnecessary, and the convenience can be improved.
[0045]
Further, the pin portion 52 of the ball removing pin 50 is very thin with a diameter of about 1.4 mm, and at the same time has high strength due to operability or portability. CL can be set to a narrow width, and can be suitably used as an opening operation member for tilting the door plate 15 by manual operation.
[0046]
Further, regarding the recess 151, the recess 151 is located on the back side of the door plate 15 in a state in which the door plate 15 is pivotally attached, and is in a state invisible to the front, that is, the player. .
Therefore, by providing the recess 151 on the back side of the door plate 15, the aesthetic appearance of the apparatus is not impaired.
[0047]
Next, a door plate having a configuration other than the door plate 15 described above will be described with reference to the drawings. FIG. 8 is an external perspective view of the door plate 45, and the attachment base plate 16 is also shown by phantom lines.
[0048]
The door plate 45 includes a horizontally long rectangular base 451, a rectangular cutout 452 that is the upper end of the base 451 and penetrates in the thickness direction substantially at the center in the width direction, and both left and right end surfaces of the base 451. It consists of a shaft part 453 protruding to the lower end side.
[0049]
The notch portion 452 is a notch into which the tip 53 of the pin portion 52 of the ball removing pin 50 as an opening operation member can be inserted, and is an insertion having the functions of the recessed portion 151 and the gap CL in the door plate 15 described above. It is empty. The width and height are set corresponding to the pin portion 52 of the ball removal pin 50, and are slightly smaller than about 1.4 mm which is the diameter of the pin portion 52 so that the pin portion 52 can be inserted. It is about 1.6-2.0 mm which is large.
[0050]
And when opening this door plate 45 by manual operation, after opening glass frame 2 ', while inserting the pin part 52 of the ball removal pin 50 with respect to the notch part 452, it grasps from this insertion state. The part 51 is moved upward toward the game board 3 as indicated by an arrow in FIG. As a result, the tip 53 of the pin portion 52 is,Edge of opening 161(Reference A in FIG. 6)It turns to the front, that is, this side as a fulcrum. At this time, the front end 53 of the pin portion 52 is in a state of being caught by the rear edge of the notch 453 indicated by reference numeral B in the drawing, so that the door plate 15 is tilted forward by its own rotation.
[0051]
Thus, the door plate 45 can be easily opened manually by the ball removal pin 50. And in this door plate 45, since the notch part 452 is visually recognizable from the front, there exists an advantage that the position which inserts the ball removal pin 50 can be known at a glance. There is also an advantage that the gap between the mounting base plate 16 and the opening 161 can be made as narrow as possible.
[0052]
However, as described above, the size of the notch 452 is set in accordance with the diameter of the pin portion 51 of the ball removal pin 50. In the case of the pin portion 51 having a diameter of about 1.4 mm, The diameter is about 1.6 to 2.0 mm, which is slightly larger than the diameter of the pin portion 51, and is not conspicuous. Thereby, it is difficult for the player to notice the notch 452.
Therefore, the cutout portion 452 does not impair the aesthetics of the apparatus.
[0053]
The bottom surface of the notch 452 is more preferably an inclined surface that descends toward the back surface. That is, the distance from the upper end of the door plate 45 to the bottom surface of the cutout portion 452 is set to be approximately the same as the diameter of the pin portion 52 of the ball removal pin 50 on the insertion portion side opened to the front of the door plate 45, and the rear side Increase continuously toward
[0054]
This is because, when the door plate 45 is opened manually by the ball removal pin 50, if the bottom surface of the notch 452 is an inclined surface that descends toward the back surface, the pin portion 52 of the ball removal pin 50 is This is because it can be inserted along the inclined surface obliquely from above, and the store clerk of the game shop can perform the opening operation of the door plate 45 without bending his / her waist while standing.
[0055]
8 is provided at the edge of the door plate 45, it may be provided at the edge of the opening 161 of the mounting base 16.
That is, the notch 452 is an edge of the opening 161 of the mounting base 16, and is at an arbitrary position on the outer peripheral edge of the door plate 45 above the shaft 453 that is a shaft attachment portion of the door plate 45. Can be provided.
