  • Patent number: 6118435
    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.
