PROBLEM TO BE SOLVED: To facilitate working such as a replacement of separation units in a spin drum type game machine which enables the detachable mounting of the separation units having reels on a cabinet. SOLUTION: A slot machine (1) which has upper and lower mask units (300) and (400) adapted to detachably close the opening of the cabinet (100) separately is, for example, provided with a speaker base plate (450) as a relay board in which a sub control board (60) provided on the upper mask unit is connected to speakers (460a and 460b) through a connector with a harness. The removal of the harness by taking off the connector improves the workability for replacing the lower mask unit. COPYRIGHT: (C)2007,JPO&INPIT
