Game machine having communication terminals

提供一种具有通信终端的游戏机，设有一个集成电路部分(3)，露出于游戏机主机(1)的一侧之外的通信终端(TA1)和(TA2)，在集成电路部分(3)和通信终端(TA1)和(TA2)之间设置一保护电路。该保护电路包括用于旁路浪涌电压的第1二极管(DD1)和第2二极管(DD2)。该第1和第2二极管(DD1)和(DD2)正向串联连接且连接点被连接到通信终端上。此外，还设置一个电阻电路(RR6)，位于集成电路部分(3)和通信终端之间的通信线上。 It is an object to provide a game machine having communication terminals wherein an integrated circuit portion is reliably protected from static electricity or a surge voltage input through the communication terminals without using communication terminals in a special configuration or providing an openable cap while reducing the overall cost. There is provided an integrated circuit portion 3 which includes communication terminals TA1 and TA2 provided such that they are exposed at one side of a game machine main body 1 and which transmits and receives data to and from another game machine through the communication terminals when the communication terminals TA1 and TA2 are connected to the communication terminals of another game machine. A protection circuit is provided between the integrated circuit portion 3 and communication terminals TA1 and TA2. This protection circuit includes a first diode DD1 for bypassing a current produced by a positive surge voltage and a second diode DD2 for bypassing a current produced by a negative surge voltage. The first diode DD1 and the second diode DD2 are series-connected in the forward direction, and the connecting point is connected to the communication terminals. Further, the protection circuit has a configuration wherein a resistor circuit RR6 is provided for reducing a current flowing into the integrated circuit portion 3 and wherein the resistor circuit RR6 is provided on the communication line between the integrated circuit portion 3 and the communication terminals.
