Description

  The present invention is a decorative body that can exhibit a characteristic effect in the progress of the game by opening and closing and moving the decorative body in and out in a direction substantially parallel to the board surface on the game board surface constituting the pachinko gaming machine. The present invention relates to units, game boards, and pachinko machines.

In pachinko machines, various board parts such as a prize opening, windmill, variable display device, and lighting device are provided on the board surface of the game board in order to diversify the contents of the game, winning prizes during the game, and other situation changes The stage effect is enhanced by moving the movable panel surface parts in various directions.
For example, when a game ball wins a start winning opening provided on the game board, the symbol displayed on the variable display device in the game board starts to change, and the symbol stopped after a predetermined time elapses is a predetermined jackpot symbol. When it becomes, it becomes a big hit state, and a player can acquire a lot of balls. In such a gaming machine, various display effects are performed in order to enhance the interest of the game.
For example, Patent Document 1 relating to the proposal of the present applicant includes a first movable accessory that reciprocates in the left-right direction parallel to the board surface of the game board, and a second movable accessory that reciprocates in the front-rear direction of the game board. , An accessory device including the above is disclosed. According to this, it is possible to realize an effect corresponding to the complexity and sophistication of game contents.

Patent Document 2 also discloses a configuration for operating the first movable member and the second movable member.
However, when each movable accessory is moved up and down and left and right using the gear mechanism, it is difficult to maintain the state where the movable accessory is stopped at the retracted position. In other words, due to backlash between gears, dimensional error between members, etc., the movable accessory often stops in a state of being deviated from the original stop position to the game area side, obstructing the path of the game ball, This will cause the game to become less fun and less fun.
Such inconvenience is likely to occur in a board surface component having a structure in which a movable accessory is attached to the tip of a long arm that rotates in a direction parallel to the board surface around a rotation axis provided at one end. This is because when the long arm is stopped at the retracted position because the distance between the rotating shaft provided at one end of the long arm and the movable accessory provided at the other end is long, the long arm and the movable arm This is because it is difficult to reliably stop the retracted position due to the weight of the accessory and the backlash of the gear portion.

For example, a long arm made of a resin material or a metal member such as iron is fixed to the movable accessory side, and a permanent magnet is fixedly arranged on the game board side as a measure for reliably stopping the movable accessory at a normal retreat position. Therefore, it is conceivable to hold the metal member by a permanent magnet when the movable accessory reaches the stop position, but it is only for positioning with respect to the long arm made of resin material or the movable accessory. Since it is necessary to make a design change for attaching a dedicated metal member, which leads to an increase in the number of parts and an increase in the number of assembling, it is not a good idea. In particular, when the target part to which the metal member is to be attached and the member located in front of the metal member are made of a transparent material, the appearance of the metal member is deteriorated because the metal member is viewed from the front.
