PROBLEM TO BE SOLVED: To provide a ball putout device capable of being reduced in size, requiring only one ball detection device to simplify wiring and reduced in manufacturing costs. SOLUTION: A supply passage 17 is bent into an L with a vertical gutter section 19a and a lateral gutter section 19b so that they may enclose a drive motor 21, an exhaust passage 20 to which a front edge of a lead screw 27 intervenes is formed in the end of each lateral gutter section 19b, the outer circumference face at least front side of a lead screw 27 is tapered to narrow gradually toward the front edge, a passage wall 32 in the exhaust passage 20 slopes along the gradient of the tapered face section 29a of the lead screw 27 and an exhaust port 34 is established to the lower end, an attachment space S is formed below the inclined passage walls 32, 32 of the exhaust passage 20, and, a ball detection machine 35 electrically detecting the game ball losing support of a ball supporting part 30 of the lead screw 27 is located in the attachment space S.
