PROBLEM TO BE SOLVED: To provide a touch operation input device capable of detecting both a touch operation position and an operator by sharing electrodes without influencing the detection of the touch operation position.SOLUTION: At a time of controlling a selected electrode driver to select a selected electrode, a controller controls the selected electrode driver to select a seated electrode other than the selected electrode. More specifically, a touch operation position is detected by detecting a pulse signal from the selected electrode driver by scanning a scan electrode, and a signal from an output device is detected while setting the timing of detecting a capacitance between the seated electrode and the selected electrode, as the timing different from that of detecting the touch operation position, to timing between scan intervals of the scan electrode or the like when the selected electrode driver switches the selected electrode. 【課題】タッチ操作位置の検出に影響を与えることなく、電極を共用してタッチ操作位置の検出と操作者の検出の双方の検出を行うことが可能なタッチ操作入力装置を提供することを目的とする。【解決手段】コントローラが選択電極ドライバを制御して選択電極を選択する際に、選択電極以外に着座電極を選択するように制御する。更に具体的には、タッチ操作位置の検出は、選択電極ドライバからのパルス信号を走査電極の走査よって検出し、選択電極ドライバが選択電極を切り換える際に、タッチ操作位置の検出とは異なるタイミングとして、着座電極と選択電極間の静電容量を検出するタイミングを走査電極の走査間等に設けて、出力装置からの信号を検出する。【選択図】図２
