  The present invention relates to a gaming machine such as a pachinko gaming machine such as a seven machine or a property, or a combination gaming machine (arranged ball gaming machine), and more particularly to a gaming machine equipped with a prize winning device.

  In a pachinko machine, a big hit state occurs when a symbol that has started changing display due to winning a start opening is stopped at a specific symbol, and the big winning opening is opened and a predetermined number (for example, 10 or 9) of games. The round until the ball enters and closes is repeated a plurality of times to obtain a large number of prize balls.

FIG. 16 shows a cross-sectional configuration of such a large winning device J33. As shown in FIG. 16, the big prize device J33 is configured to open and close the big prize opening J330 by operating a horizontally long opening and closing plate J331 by a solenoid J332, and the upper and lower plates J331 are centered on the lower end and the upper end is a game. By moving to the front side of the board J20, the game ball is easily opened (see, for example, Patent Document 1).
JP 2001-327687 A

  However, in the above-described prior art big winning device, the open / close plate J331 rotates around the lower end and the upper end pivots to the front side of the game board J20, so that the game ball flowing down to the big prize opening when the open / close plate J331 closes Ball biting between the opening / closing plate J331 and the special winning opening J330 is likely to occur.

  FIG. 17 shows a perspective view of a state in which a game ball is engaged with a ball. In FIG. 17, when viewed from the front, the ball is bitten at the left end of the special winning opening J330. As shown in FIG. 17, when the ball bite occurs, the special prize opening J330 is not completely closed, so that a gap is formed between the right prize opening J330 and the opening / closing plate J331. For this reason, as shown in FIG. 17 (a), even if the number of game balls that have entered the big prize opening J330 reaches a predetermined number that can be entered in one round, the gap between the big prize opening J330 and the open / close plate J331 is not reached. A game ball having a design value or more may enter the winning prize opening J330 from the gap. Alternatively, as shown in FIG. 17 (b), a game ball may stop in the gap between the big prize opening J330 and the opening / closing plate J331, and when a player gives a strong impact by hitting the game machine or the like. In some cases, a game ball that has stopped together with a game ball that has bitten the ball enters the grand prize winning opening J330.

  Also, by inserting a piano wire or the like into the front frame of the game board and pulling the opening / closing plate, the grand prize opening is forcibly opened, and the game ball is entered into the grand prize opening to obtain a prize ball illegally. Cheating may occur.

Tei is characterized in Rukoto.

Such an opening / closing plate rotates in the clockwise direction when shifting from the closed state to the open state, and rotates in the counterclockwise direction when shifting from the open state to the closed state, so that the opening / closing plate is in the open state. When shifting from the closed state to the closed state, the first plate portion positioned on the rear side rotates upward and the second plate portion positioned on the front side rotates downward, so that the game ball rides on the opening / closing plate. Even so, the game ball falls to the front side of the game board. Thereby, it is possible to prevent the occurrence of a ball bite in which the game ball is sandwiched between the special winning opening and the opening / closing plate.

  Further, when the opening / closing plate shifts from the closed state to the open state, the first plate portion positioned above rotates rearward, and the second plate portion positioned below rotates forward. Thus, even if the upper end of the opening / closing plate is hooked with a piano wire or the like, the opening / closing plate is pulled in the direction opposite to the rotation direction of the opening / closing plate, and the opening / closing plate cannot be rotated. As a result, it is possible to prevent an illegal act that attempts to open the special winning opening illegally.

  In addition, the rotating shaft is located on the rear side of the board surface of the game board, and the opening / closing plate is opened / closed when the upper end of the first plate part is located on the rear side of the board surface of the game board in the closed state. It becomes difficult to hook the upper end of the board with a piano wire or the like, and it is possible to prevent fraudulent acts that attempt to open the grand prize opening illegally.

  In addition, even if the upper and lower plates are configured so that the upper end of the first plate is positioned above the upper end of the big prize opening in the closed state, the upper and lower plates may be hooked with a piano wire or the like. The end portion of the first plate portion is caught by the upper end of the big prize opening and cannot move to the front side of the big prize opening. As a result, it is possible to reliably prevent an illegal act that attempts to open the grand prize opening illegally.

  In addition, the open / close plate is configured so that the plate surface of the first plate portion is shifted downward from the plate surface of the second plate portion in the open state, so that the game ball that has entered the big winning opening is smoothly It is possible to flow down to the rear side.

  In this specification, “the front side of the game board” means the side near the player (front side), and “the back side of the game board” means the side far from the player (back side). .
