Patent number: 10514781Abstract: A position detection apparatus of the electrostatic coupling type is provided, to detect not only a position of a pointer but also information other than the position information such as, for example, pointer pressure or side switch information. The pointer transmits two codes such that a pressure applied to a pen tip is associated with a time difference between the two codes. A position detector carries out a correlation matching operation between signals generated in reception conductors and correlation calculation codes corresponding to the two codes, to thereby detect a position on a sensor section pointed to by the pointer from a result of the correlation matching operation and based on at least one of the codes.Type: GrantFiled: February 14, 2018Date of Patent: December 24, 2019Assignee: Wacom Co., Ltd.Inventors: Yasuo Oda, Sadao Yamamoto, Yoshihisa Sugiyama

Patent number: 10345983Abstract: An inputting apparatus of the electromagnetic induction type may provide a transmission signal of a sufficient signal level to a position indicator. A process controlling unit controls a selection circuit on the basis of a reception state of a reception signal received by each of a plurality of electrodes and detected by a reception signal processing circuit such that a first signal for transmitting a transmission signal is supplied to a first electrode at which the reception signal indicates the highest signal level. Further, the process controlling unit controls the selection circuit such that a second signal is supplied to a second electrode at which the signal level of the reception signal is lower than a predetermined signal level. Consequently, signals can be transmitted to a position indicator from both the first electrode, which most receives the signal from the position indicator, and the second electrode spaced from the first electrode.Type: GrantFiled: March 10, 2017Date of Patent: July 9, 2019Assignee: WACOM CO., LTD.Inventors: Takeshi Kobori, Yoshihisa Sugiyama
