Claims

[Claims for Utility Model Registration] 1. A pressure sensor installed at least near the line along the line direction, and a determining means for determining the relative arrival position of the pole with respect to the line based on the output signal from the pressure sensor. Equipped with a ball position determination device. 2 Utility Model Registration Scope of Claim 1 In the ball position determining device according to claim 1, the pressure sensor includes a plurality of elongated pressure-sensitive switches arranged in parallel in the line direction, and the determining means includes a plurality of elongated pressure-sensitive switches arranged in parallel in the line direction. A ball position determining device characterized in that the relative position is determined based on a time-series ON pattern of a switch.
