    • 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.
    • 具有触摸面板的显示单元包括按压检测开关,用于以超过预定水平的压力检测触摸面板上的压力,以输出压力检测信号;响应于按压检测信号的驱动信号发生电路, 驱动信号,由驱动信号驱动的驱动部分,以驱动触摸面板移位,从而向操作者提供触觉反馈;以及AND电路,用于在从符合检测电路接收到重合检测信号时输出AND信号 和来自按压检测开关的按压检测信号,以及一个门电路,用于当AND电路的AND信号不被供给时,禁止来自操作位置检测电路的操作位置信号的通过,并允许操作的 来自AND电路的AND信号被提供时的位置信号。 具有触摸面板的显示单元确保防止由操作者引起的操作错误仅将触摸面板上的手指滑动或意外地触摸触摸面板。
