IPC: A63F7/02
Filed: 2000-09-12
Abstract: PROBLEM TO BE SOLVED: To provide a ball-withdrawing apparatus which makes ball- withdrawing operation easy to do and has a simple structure and a reduced cost. SOLUTION: A case body has an electromagnetic solenoid 28 which is a switch operation source of a control member 68 controlling the rotation and the halt of a ball sending body 67. When the electromagnetic solenoid 28 is at the degaussed state, the control member 68 is held at a halt position to halt the rotation of the ball sending body 67 by the energizing force of an extension spring 71. When the electromagnetic solenoid 28 is at the excited state, the control member 68 is held at a release position to allow the rotation of the ball sending body. An operation member 81 to switch the control member from the halt position to the release position is fixed on the case body. By carrying out a pushing operation of the operation member 81, the control member 68 is tilted to change from the halt position to the release position against the energizing force of the extension spring 71.  If the pushing pressure onto the operation member 81 is removed, the control member 68 returns automatically to the halt position by the energizing force of the extension spring 71.
