<P>PROBLEM TO BE SOLVED: To improve usability of a display input device by delaying acceptance of a specific type of input among erroneous input resulting from fast-pressing due to habitual practice and accepting only accurate input while suppressing decrease in operational efficiency, so as to exonerate a user from do-overs of time-consuming settings. <P>SOLUTION: A display input device comprises: a display part (liquid crystal display part) for displaying a plurality of keys on a screen; a touch panel part for detecting a position pressed in the display part; and a display control part for accepting input by recognizing a pressed key and controlling display of the display part to make the display part switch the display in response to the pressed key. The display control part measures time intervals between pressing of the keys, and accepts key input in an erroneous input prevention mode which delays acceptance of input by specific keys specified beforehand when the keys are pressed at a time interval shorter than a preset reference time. <P>COPYRIGHT: (C)2013,JPO&INPIT |
