PROBLEM TO BE SOLVED: To solve problems when a plurality of conventional wall sockets are connected one after another to connect power cords to the respective wall sockets (in the state of so-called "many loads on one electrical outlet"), wherein it is difficult to feed stable power supply to all the game machine casings and wherein the operation of electronic circuits mounted on the casing side and electronic circuits on the game machine side is instable to cause malfunction because the voltage becomes lower toward the game machine casings on both ends. SOLUTION: A male plug 4 is attached to the rear side of a casing A, which is the game machine casing permitting replacement of a pachinko machine or a pachinko slot machine. The power supply device in a game machine such as a pachinko machine is composed of a female plug 6 which can be connected to the male plug, and a male plug 62, which can be connected to a power outlet 7, at the other end of a power cord 61 whose one end is connected to the female plug. The cord is formed with different lengths, which can be selected according to the distance from the game machine casing to the power outlet. COPYRIGHT: (C)2009,JPO&INPIT
