PURPOSE:To obtain a miniature input device of simple constitution which enables the multiple-item inputting without using several independent switch elements. CONSTITUTION:This device is provided with contact part 2 constituted by providing either conductive rubber 15 turning ON-OFF the intersection of a matrix between column and row layers and conducting electrically only at its pressure-applied part or pressure-sensitive rubber sheet 14 whose opposite part to the intersection of the matrix has been punched out, and small-booklike conductor 12 forming the matrix at column and row layers. Furhter, detacheable display sheet with a plural number input items written ant intersections along column and row conductors 12 is arranged at the upper part of contact part 2, and display windows 10 are provided corresponding to intersections of the matrix; and then, the positioning mechanism is provided which has the click function of making it possible to display items of sheet 22 through windows 10 and detecting cover 3 and the sliding position of cover 3. Next, intersections of the matrix which correspond to input items are depressed through windows 10 of cover 3, thereby making contact parts 2 conductive. |
