<p>PROBLEM TO BE SOLVED: To obtain a contact sensing sensor with a large degree of free arrangement with small and simple configuration. SOLUTION: The contact sensing sensor 10 is set in a windwheel or a contrivance being a member to be an operation start trigger by the contact of a pachinko ball. Then, it is detected that the pachinko ball is brought into contact with the windwheel or the contrivance. This pachinko machine contact sensing sensor 10 is provided with a piezoelectric polymer material-made detecting plate 12 which is formed in a film sheet shape. Then, it is detected that the pachinko ball is brought into contact with the windwheel or the contrivance based on an electric signal generated with the deformation of the detecting plate 12 by the contact of the pachinko ball.</p> |
