<p>PROBLEM TO BE SOLVED: To provide a matrix-type input device capable of easily detecting a position pressed to a touch panel, in a short time. SOLUTION: This matrix-type input device comprises column conductive sheets Ai, Bi, etc., composed of first rectangular pieces insulated from each other, row conductive sheets Aj, Bj, etc., composed of second rectangular pieces insulated from the column conductive sheets Ai, Bi, etc., while intersecting with the same, a panel-shaped switch part 20 having touch keys 22 electrically connecting the column conductive sheets Ai, Bi, etc., to the row conductive sheets Aj, Bj, etc., by pressing the column conductive sheets Ai, Bi, etc., an image display part 12 oppositely abutted on the switch part 20, and capable of displaying an image such as characters, a voltage applying means for successively applying the voltage at least for every other column conductive sheets Ai, Bi, etc, arranged in parallel in a thinning-out state, and a detecting means for specifying the pressed touch keys of the column conductive sheets Ai, Bi, etc., and the row conductive sheets Aj, Bj, etc.</p> |
