Abstract

PURPOSE:To reduce the burden to a player providing a gate plate which is normally closed by a spring, at an opening for dropping balls in the leading edge part of the bottom plate of a ball return chute for excess balls upon exchange with a premium, and by taking out balls from the opening after the gate plate is pushed. CONSTITUTION:When a calculated number of excess balls B are accumulated in a return chute 7, if a gate plate 23 is pushed in the direction of the arrow C, the gate plate is moved by overcoming a spring 24 so as to open an opening 22 in order to drop the balls B. Accordingly, the balls B can be received by the palm of a human hand or a receiving box. The manipulation for receiving the balls B dropping from the opening 22 can be simultaneously made by the hand or the box. In such a case that a cut-out is formed in the lower part of a front plate 25d so that the latter is floated up from a bottom plate 21, the area of the opening 22 is increased and the balls drop also obliquely forward, and accordingly, even though a large number of excess balls are present, they can be rapidly discharged. Since it is sufficient that the force of the spring 24 is weak, the manipulation can be made one hand, thereby it is possible to reduce the burden to a player.
