Abstract

PURPOSE: To improve the operability, by recognizing coordinate points indicated with a finger by logical signals outputted in series from a shift register.
CONSTITUTION: It is arranged that an inputted coordinate is recognized by placing an electrode conductor group for detecting coordinate on an electrode to which a pulse voltage is supplied, so that they are electrostatically coupled with each other, and by detecting variations of level of the pulse voltage induced from electrodes 2 and 2' of at least one electrode conductor based on approach of a finger of operators, and, moreover, that numerous detected contents of the electrode conductor group are transferred to an external central processor through an interface after they are converted into series logical information by parallel input shift registers SRX and SRY. Therefore, careful coordinate inputs can be performed and the number of signal lines between interfaces can be reduced as much as possible.
