<p>PURPOSE:To give the degree of freedom to a display form of a key, and to discriminate a function of a key element by display information, by executing input processing being function discriminating processing of the key element which has been touched independently from the display form of the key. CONSTITUTION:A touch system input device 5 is constituted of a plane type display 2, a transparent type touch panel 3 and a controlling circuit 6, and the circuit 6 is provided with a touch panel input circuit 61, a displaying circuit 62, a RAM 63, a ROM 64, and a microprocessor 65. In a memory table 63a of the RAM 63 of this circuit 6, information for showing a function of each key element is stored in advance in accordance with a display form of the display 2. In this state, when a key has been depressed, the function of the key element concerned is discriminated by detecting a key number of the depressed key element, and referring to information of a table 63a corresponding to its number.</p> |
