Title: Pachinko ball sensor
Inventor: ISHIBASHI KEISUKE
IPC: A63F7/02
Filed: 1989-05-22
Abstract: PURPOSE:To eliminate ill influence of external factors without causing wear of contacting parts and chattering, etc., which is likely with contact type, by displacing a movable piece with a pachinko ball (Japanese pinball) passing through a sensing hole, and by changing the distance of a Hall element and magnetic resistance element from the magnetized portion. CONSTITUTION:When a sensing hole 3 is free from passage of any pachinko ball 2, a movable piece 5 is energized toward the hole 3 by a leaf spring 7, and a ball sensing part 5a at one end is protruding into the hole 3. On the other hand, the magnetized portion 10 of this movable piece 5 at its other end is positioned apart from a Hall element 6, which generates Hall electromotive force, and passage of the sensing hole 3 allows the mentioned sensing part 5a of movable piece 5 to push the pachinko ball 2 to cause intrusion of the piece 5 into a mounting hole 8 against the force of the leaf spring 7. With compressive deformation of this leaf spring 7 the movable piece 5 displaces toward the Hall element 6 to permit the magnetized portion 10 to approach the Hall element 6, and thus a magnetic field and electromotive power are generated.
