を特徴とするスイツチ入力読み込み装置。[Claim for Utility Model Registration] A digital/analog converter that converts a digital quantity into an analog quantity obtains different analog quantities according to the on/off status of each of a plurality of switches, and converts this analog quantity into an analog/digital converter. A switch input reading device that individually determines on/off of a plurality of switches based on digital quantities obtained by conversion by a digital converter, wherein the digital quantities are sampled at each predetermined conversion timing in the analog/digital converter. 1. A switch input reading device comprising a discrimination permission means for permitting discrimination of an on/off state based on the digital quantity only when the digital quantity remains at the same level continuously for a predetermined number of times or more.
