PROBLEM TO BE SOLVED: To provide a game machine in which, whether a ball tank is full of balls can be detected, and the attaching and detaching work of the ball tank is facilitated. SOLUTION: At a most upstream part on the bottom surface of the ball tank 42, a detection board 160 which is tilted by riding over of a game ball BL and displaces a lever part 166 downward is provided. On the rear surface 14A of an inner frame 14, a switch 170 is installed through an installing board 178. Regarding the switch 170, when the tank 42 is fitted to the inner frame 14, a movable arm 174 is arranged nearly horizontally in the front and rear direction of the lever part 166 of the detection board 160, and a roller 176 installed at the distal end part of the movable arm 174 is arranged so as to abut on the lower surface of the lever part 166. Since there is no need to carry out wiring processing of the switch 170 in the case of attaching and detaching the tank 42 to/from the inner frame 14 in a detector 180 provided with the detection board 160 and the switch 170, attaching and detaching of the tank 42 are facilitated.
