PROBLEM TO BE SOLVED: To dissolve a problem caused by that a ball supply cassette for supplying game balls is not used for taking out the game balls from a game machine body but supplying them to the game machine body alone, the ball supply cassette can be detached outside the circulating passage of the game balls and a cassette for use in replacing a game ball constitutes a part of a circulating passage of the game ball in a enclosed ball type game machine. SOLUTION: An enclosed ball circulating device is provided with a cassette mount part 270 for mounting the ball supply cassette 340 which can store a predetermined number of game balls B to be supplied to the enclosed ball circulating device and be detachably attached to the enclosed ball circulating device. The game balls B flowing out from a storage opening part 341 formed in the ball supply cassette 340 mounted on the cassette mount part 270 of the enclosed ball circulating device are supplied from a supply opening part 267 formed in the cassette mount part 270 and communicated with the circulating passage 220 of the enclosed ball circulating device to the enclosed ball circulating device.
