Abstract
A display unit with touch panel includes a press detection switch for detecting a press on a touch panel at a pressure exceeding a predetermined level so as to output a press detection signal, a driving-signal generating circuit responding to the press detection signal to generate a driving signal, a driving portion actuated by the driving signal to drive the touch panel into displacement thereby providing an operator with a tactile feedback, and an AND circuit for outputting an AND signal upon receipt of both of a coincidence detection signal from a coincidence detecting circuit and the press detection signal from the press detecting switch, and a gate circuit for inhibiting a passage of the operated-position signal from the operated-position detecting circuit when the AND signal from the AND circuit is not supplied and permitting the passage of the operated-position signal when the AND signal from the AND circuit is supplied. The display unit with touch panel ensures the prevention of operation errors caused by the operator merely sliding his finger on the touch panel or accidentally touching the touch panel.
