<p>PROBLEM TO BE SOLVED: To provide a game machine of a structure hardly influenced by noises, by devising a connector and a wiring pattern in a control board.SOLUTION: A control board 27 comprises: a connector 60 having a plurality of terminals 61 arranged in two rows for being connected electrically through a harness with another substrate; power source patterns 51, 53 and 54 connected with a power terminal of a plurality of terminals of the connector; a ground pattern 56 formed to enclose the power source patterns and connected with the ground terminal of the terminals of the connector; and electronic parts 71 to 73 fed with en electric power source through the power source patterns and said ground pattern. Of the terminals of the two-row arrangement of the connector, at least two adjoining terminals in the row direction are the power source terminals for the same power source, and the width W of the power source patterns extracted from those power source terminals and leading to at least one of said electronic parts is formed to a width of two or more of the terminals.</p> |
