Abstract: A plurality of medals are placed both on a fixed table and a movable table. A player supplies medals one by one on the movable table via a medal feeding rail. The movable table moves forward and backward in a reciprocating motion to drop medals placed on the fixed table into a medal outlet so as to give the medals to the player. A field table which is placed under the fixed table revolves around a tower, while containing a large number of medals accumulated therein, thereby circulating a large number of accumulated medals. Medals in the field table are automatically taken out, when the amount being in excess, by an overflow prevention device. Thus, the game machine permits the player to continue the game, free from concern about any medal overflowing from the field table.

Abstract: A shovel type game machine is adapted to pick up articles on a display platform. The game machine has a resiliently deformable bucket, and a bucket drive device for supporting the top of the bucket for tilting movement. The bucket drive device causes the bucket to perform its shoveling operation while tilting the bucket forwardly with a given force. The shoveling operation is performed by moving the pivot center of the bucket downwardly. Thus, the bucket can be resiliently deformed to move its tip below the articles.
