Description

  It relates to gaming machines.

  In a pachinko machine, a ball that has been bulleted flows down a game area (an area formed on or near the game board surface for realizing a game or production by the flow of the game ball). In the course of the flow, the game ball rolls while colliding with a game nail or windmill in the game area, and the flow direction changes. As a result, if a game ball wins at various winning holes arranged on the game area, a predetermined prize ball (prize ball) will be paid out, but on the other hand, the ball flows into the out port without winning any of the winning holes. If you do this, the prize ball will not be paid out. The player enjoys the game by demonstrating his / her skill in the ball or using the chance of the game ball flowing down and expecting the game ball to be won and the prize ball paid out.

  As game parts to be arranged in the game area of this pachinko machine, flow path changing members such as game nails, various winning holes through which game balls can flow in, pass gates for detecting the passage of game balls, images for performing image effects There are display means and the like, and these game parts are arranged on the game board.

  The game board is fixedly arranged on the front frame at a fixed position defined on the front frame of the gaming machine. Further, in Patent Document 1, when the game board is stored in the game board storage part provided in the front frame and the back mechanism board is locked to the front frame from the back side, the pressing part of the ball storage tank provided in the back mechanism board Discloses a gaming machine that presses the game board and maintains the stored state of the game board.

  A large number of the game nails described above are arranged in the game area of the game board of the pachinko machine, but countless game balls fall and collide with these game nails during the game. As a result, the game nail may be gradually tilted downward or obliquely downward due to the impact of a fall or collision of the game ball over a long period of time. In amusement halls, it is necessary to always maintain the state of the game nail at a predetermined angle, so maintenance (repair) of the game nail is performed regularly or irregularly. For maintenance of the game nail, a dedicated repair tool called a dedicated hammer and gauge bar is generally used.
