PROBLEM TO BE SOLVED: To provide a game machine which can prevent illegal alteration of contents stored in an IC (integrated circuit) tag and a monitoring means and illegal alteration of an operation control program of the monitoring means. SOLUTION: The IC tag 86 storing identification data is attached to a cover member 202 of a control box 200 in a game machine. An antenna 6 is attached to an attaching piece 3 projected from an outer case body 204 storing an R/W (reader/writer) unit 56. An antenna inserting hole 226 is bored in an inner case body 203 storing a main board 41. When the cover member 202 is closed, the attaching piece 33 is inserted into the antenna through hole 226 and RF (radio frequency) transmission/reception between the antenna 68 and the IC tag 86 is enabled, but when the cover member 202 is opened, RF transmission/reception between the antenna 68 and the IC tag 86 is disabled.
