Title (EN) POINTING DEVICE
(FR) DISPOSITIF DE POINTAGE
(JA) 位置指示器
Abstract:
(EN) An objective of the present invention is to facilitate accurate pointing even when a pointing device is at an incline relative to an input surface of a sensor of a position detection device. Provided is a pointing device having a pen shape, for interacting electrostatically with a sensor of a position detection device. The pointing device comprises: a conductive core body, positioned such that a leading end part protrudes from an aperture of one end side of a pen-shaped casing body in the axial direction thereof; a ring-shaped conductor encircling the core body; and a signal transmission control circuit for generating a signal for electrostatically interacting with the sensor and supplying the generated signal to the core body. The signal transmission control circuit further comprises a configuration such that an AC signal, having an inverse phase to an AC signal transmitted from the core body to the sensor, is transmitted from the ring-shaped conductor.
(FR) L'objectif de l'invention est de faciliter un pointage précis même lorsqu'un dispositif de pointage est incliné par rapport à une surface d'entrée d'un capteur d'un dispositif de détection de position. À cet effet, l'invention concerne un dispositif de pointage ayant une forme de stylet et permettant d'interagir de manière électrostatique avec un capteur d'un dispositif de détection de position. Le dispositif de pointage comprend : un corps de noyau conducteur positionné de façon à ce qu'une partie d'extrémité avant ressorte d'une ouverture d'un côté d'extrémité d'un corps de boîtier en forme de stylet dans la direction axiale de celui-ci; un conducteur en forme d'anneau encerclant le corps de noyau; et un circuit de commande de transmission de signal permettant de générer un signal pour une interaction électrostatique avec le capteur et de fournir le signal généré au corps de noyau. De plus, le circuit de commande de transmission de signal possède une configuration telle qu'un signal CA, ayant une phase inverse à un signal CA transmis par le corps de noyau au capteur, est transmis par le conducteur en forme d'anneau.
(JA) 位置指示器が位置検出装置のセンサの入力面に対して傾いていても、正確な位置指示を可能とする。 ペン形状を有し、位置検出装置のセンサとの間で静電的にインタラクションする位置指示器である。ペン形状の筐体の軸心方向の一端側の開口から先端部が突出するように配置された導電性を有する芯体と、芯体を取り囲むリング状導体と、センサとの間で静電的にインタラクションするための信号を生成して、その生成した信号を芯体に供給する信号送信制御回路を備える。さらに、信号送信制御回路は、芯体からセンサに対して送出される交流信号とは逆相の交流信号がリング状導体から送出されるようにする構成を備える。
