<p>PURPOSE:To detect accurately and simply moving conditions such as a moving direction and the like of a body to be detected such as a pachinko ball and the like. CONSTITUTION:A coil is formed on a circuit board 13, and two detecting portions 10A, 10B, which are composed of oscillating circuits, oscillating using the inductance component of the coil, and switching circuits, are adjacently established. The detecting portions 10A, 10B determine the moving conditions of a body to be detected by the output conditions of the two detecting portions 10A, 10B. The changing orders of the outputs of the detecting portion 10A and the detecting portion 10B are different according to the moving directions when a pachinko ball P passes through a through hole. Thereby the moving direction is detected so as to detect the total number of the pachinko balls P supplied to a pachinko playing board 3.</p> |
