Holding structure for a touch panel

A holding structure for a touch panel, comprising:

• a display panel for forming a display screen;
• a touch panel disposed outside the display panel, for allowing an input operation;
• an elastic supporting frame for holding the display panel at an entire peripheral edge thereof and supporting the touch panel in parallel with the display panel;
• a piezoelectric device disposed at a side edge of the touch panel, for applying vibration to the touch panel in accordance with the operation of the touch panel;
• and
• a casing for holding the display panel and the touch panel via the elastic supporting frame, the casing having an opening through which the touch panel is exposed, wherein
• the elastic supporting frame holds the touch panel at an entire peripheral edge of the touch panel and includes a plurality of touch panel supporting portions for supporting the touch panel at a side edge portion of a rear surface of the touch panel, and
• the touch panel supporting portions of the elastic supporting frame support portions where nodes of the vibration of the touch panel by the piezoelectric device exist.
