Gaming Machines

Abstract

To provide a game machine that can suppress a decrease in reliability.SOLUTION: A game machine having multiple circuit boards on which multiple electronic components are mounted includes a specific control circuit board that has a solid ground. On the front surface of the specific control circuit board, a mounting portion where electronic components are mounted and a non-mounting portion where electronic components are not mounted are formed. A specific mounting portion in the mounting portion includes a specific insulating portion in which a surrounding copper foil is removed and a specific conductive portion connected to the solid ground where the surrounding copper foil remains. A special non-mounting portion in the non-mounting portion includes a special insulating portion in which the surrounding copper foil is removed and a special conductive portion connected to the solid ground where the surrounding copper foil remains. The specific mounting portion is formed of a rectangular copper foil portion, and the special non-mounting portion is formed of a circular copper foil portion.SELECTED DRAWING: Figure 129

Claims

[Claim 1] A gaming machine having a plurality of substrates on which a plurality of electronic components are mounted, A specific control board having a solid ground is provided, At least one of the front and rear substrate surfaces of the specific control board is provided with a mounting section on which the electronic component is mounted; a non-mounting portion where the electronic component is not mounted; an IC having two sets of opposing sides; a capacitor disposed adjacent to the IC on a specific side of the IC; a specific mounting portion among the mounting portions is connected to a solid ground of the specific control board by a thermal pattern formed so as to be positioned around the specific mounting portion; a special non-mounting portion of the non-mounting portion is connected to a solid ground of the specific control board by a thermal pattern formed so as to be positioned around the special non-mounting portion; At least one of the connection terminals of the capacitor is soldered to a first specific mounting portion of the specific mounting portions and is connected to a solid ground of the specific control board; the IC has a plurality of connection terminals formed along at least one of the pair of opposing sides not including the specific side, Furthermore, among the multiple connection terminals of the IC, a special connection terminal arranged on a special side opposite to the specific side is soldered to a second specific mounting portion of the specific mounting portions and connected to a solid ground of the specific control board, At least one of the first specific mounting portion and the second specific mounting portion is formed of a rectangular copper foil portion, The special non-mounting portion is formed of a circular copper foil portion.
