GAME BALL DETECTION DEVICE, GAME MACHINE ACCESSORY DEVICE AND GAME MACHINE

PROBLEM TO BE SOLVED: To miniaturize and simplify the entire device by forming a small and thin light emitting board, and to facilitate visual recognition of a light emitting element. SOLUTION: A recess 13d is formed in a front wall part 13c of a front decorative part 13 in parallel with a board face 2a of a game board 2. The light emitting board 15 is held widthwise between a bottom face 13e of the recess 13d and an inserting tip face 11c of a proximity switch 11 opposite to the bottom face 13e. The light emitting element 16 is mounted on a main surface of an inserting tip of the light emitting board 15 so that an optical axis O is perpendicular to the board face 2a of the game board 2. When the proximity switch 11 detects a game ball in a detection region 11b, a light emitting mode of the light emitting element 16 is changed. A display hole 13f having a circular cross section is pierced through the front wall part 13c of the front decorative part 13 so that its center corresponds to the optical axis O of the light emitting element 16. Thereby, a player can directly recognize light of the light emitting element from outside. COPYRIGHT: (C)2008,JPO&INPIT
