PROBLEM TO BE SOLVED: To provide a game machine capable of preventing illegal alteration of both contents stored in the monitor means of an IC (integrated circuit) tag and the operation control program of the monitor means. SOLUTION: The IC tag 86 for storing identification data is attached to the cover member 202 of a control box 201 in a Pachinko machine. An attachment piece 33 is projected in an outer case body 204 with an R/W (reader/writer) unit 56 stored therein. An antenna 68 is attached to the attachment piece 33. An antenna through-hole 226 is pierced in an intermediate case body 203 for storing a main control board 41. In the control box 201, the attachment piece 33 is put through the antenna through-hole 226 when the cover member 202 is closed, so as to perform RF (radio frequency) exchange between the antenna 68 and the IC tag 86. When the cover member 202 is opened, RF exchange is not performed between the antenna 68 and the IC tag 86. COPYRIGHT: (C)2004,JPO
