PROBLEM TO BE SOLVED: To provide a game machine capable of reducing chances of an oversight of a fraudulent opening. SOLUTION: An opening trace giving part 400 of a board box 263 includes an ink capsule 280, a storage hole 405 formed when respective hole parts 401 and 403 of mating faces of both cases (a box base 265 and a box cover 267) are connected together by a slide-mounting state of the both cases, and a coil spring 407 in the hole part 401. When the box cover 267 is slidingly mounted with the ink capsule 280 pushed in the hole part 401, a part of the ink capsule 280 enters in the hole part 403 to reduce the resilient deformation of the coil spring 407, the ink capsule 280 in the storage hole 405 is cut by slidingly opening the box cover 267, and liquid flows out therefrom to be stuck to the board box 263, so that, if the board box 263 is opened, the part stuck with the ink is conspicuous so as to reduce the oversight of the trace.
