Claims

[Scope of claim for utility model registration] A game board equipped with a guide rail, obstacle nails, multiple prize openings, etc. is removably fitted into the front frame, which is hinged to the machine frame on one side and can be opened and closed. In a pachinko machine in which a housing-shaped rear cover is provided to close the rear cover from the back side, the lower edge of the rear cover is inclined in a one-sided flow state, and an invalid ball passage is provided downward from the lower edge, An engraved passage of a predetermined width is provided in the thickness direction and along the surface of the game board, one of the engraved passages is communicated with some of the winning openings, and the other side is communicated with a part of the winning openings. A bag portion larger than this cross-sectional area is formed in the carved passage by connecting it downwardly to either an upper tray or a lower tray for storing prize balls formed on the lower front surface of the machine frame, and A rolling passage in the bag portion that communicates with the carved passage, and a rotation that is pivoted in a direction perpendicular to the rolling passage and is normally maintained in a closed state with respect to the upstream opening of the carved passage. A tamper prevention device for a pachinko machine, comprising a tamper prevention body having a flexible blocking member.
