POINTER DETECTION SENSOR AND POINTER DETECTION APPARATUS

摘要

A plurality of first conductors and a plurality of second conductors disposed in first and second directions crossing with each other are disposed in an opposing relationship to each other and in a spaced relationship by a determined distance from each other, and a variation of a capacitance formed between any of the first conductors and any of the second conductors based on a variation of a distance between the first conductor and the second conductor when one of the first conductor and the second conductor is deflected by pressing by a pointer is detected to detect a position pointed to by the pointer. A spacer is disposed between the first and second conductors in a region of a cross point such that a deflection amount of one of the first conductor and the second conductor by the pressing by the pointer has a value higher in a region other than the region of the cross point than in the region of the cross point at which the first conductor and the second conductor cross and overlap with each other.

1. A pointer detection sensor of a capacitance type, comprising:
a plurality of first conductors disposed in a first direction; a plurality of second conductors disposed in a second direction crossing with the first direction, the plurality of first conductors and the plurality of second conductors disposed in an opposing relationship to each other and spaced apart from each other, wherein, in operation, a variation of a capacitance formed between any of the first conductors and any of the second conductors based on a variation of a distance between the first conductor and the second conductor when one of the first conductor and the second conductor is deflected by pressing by a pointer is detected to indicate a position pointed to by the pointer; and one or more spacers disposed only in regions of cross points between conductors of the plurality of first conductors and conductors of the plurality of second conductors.
