PROBLEM TO BE SOLVED: To allow a worker to easily confirm that a front door is fraudulently opened, for example, during carrying a game machine with a main control board mounted on a housing inside, and easily confirm that an inspected ROM is fraudulently replaced by a so-called dirty ROM or fraudulent ROM or a currently-used board case is replaced by a board case storing a fraudulent control board. SOLUTION: This game machine is so formed that the side of the front door 3 is attached with a front door side engagement block 50 having a front door side engagement part, the side of the housing 2 is attached with a housing side engagement block having a housing side engagement part, the front door side engagement part and the housing side engagement part are engaged with each other in response to a closing operation of the front door 3, the engagement is confirmed or released via a hole 2c in the side of the housing 2 and, when the front door 3 is fraudulently opened, the cutting of a connection part of the housing side engagement part is left behind as a trace of the fraudulent opening.
