Title: Position measuring instrument for touch panel
Inventor: AARU DEBITSUDO MIIDOUZU
IPC: G06F3/048
Filed: 1990-07-19
Abstract: PURPOSE:To attain the making of an electromagnetic noise generated by a position measuring signal into low amplitude by using a signal with prescribed amplitude whose frequency changes irregularly as a position signal to be supplied to an electrode on a display plane. CONSTITUTION:Position measuring instrument finds a contact position 46 by measuring intervals between the contact position 46 and each of the electrodes 36, 38, 40, and 42. A position measuring signal source 56 generates a bipolar consecutive rectangular wave measuring signal, and sends it to the input terminal 58 of an output filter, and the measuring signal alternates between a positive voltage +V and a negative voltage -V with the frequency changing sufficiently irregularly. Especially, since the frequency of the measuring signal changes within the range of band width of 150 to 250kHz, the electromagnetic noise generated by the measuring signal is distributed to the same band area. In such a way, the electromagnetic noise can be formed in the one with comparatively low amplitude, an electromagnetic interference generated from the position measuring instrument can be reduced.
