Panel units ( to ) continuing an operation indicating panel ( ) each have a rectangular surface S with length and width each being substantially an integral multiple of a predetermined reference size (L). The panel units ( and ) are placed so that their surfaces S may be adjacent to one another. A whole surface (AS) consisting of the surfaces S of all the panel units ( to ) is formed in a rectangular shape with length and width each being substantially an integral multiple of the predetermined reference size (L). The arrangement and the like of the panel units ( to ) can be easily changed.

Operation indicator device and panel unit

In a display and input device (CP) displaying information on a display (DP) and performing changing of the information and communication through switch operating means (CSW1), the switch operating means (CSW1) are arranged on the left and right edges of the display (DP), opaque members among members forming the switch operating means (CSW1) are arranged outside the screen of the display (DP), and only transparent members are arranged on the display (DP). Thus, a switch operation can be performed while recognizing functions of the switch operating means (CSW1) and the switch operating means (CSW1) having the stroke feeling and click feeling of a mechanical switch so that an operating environment having excellent operability and implementing reliable input can be obtained.

Display and input device and display and input system

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.
