发明名称 Information display device and supporting frame for supporting a piezoelectric element for use in information display device
摘要 An information display device (1A) comprises a touch panel (TP), an information display panel (LCD) located under the touch panel (TP) and four strip-like piezoelectric elements (E), which are caused to be vibrated and displaced by pressing force generated when the touch panel (TP) is pressed, being disposed at the outer peripheral portion of the touch panel (TP), wherein both end portions of each strip-like piezoelectric element (E) are supported by surface-like holders (112A, 112B) with twist resilient deformation structures and a rotary shaft (113) so that each strip-like piezoelectric element (E) may not be disturbed from being vibrated and displaced. In this touch panel type information device, both end portions of a plurality of strip-like piezoelectric elements are supported by the supporting member having the holders with the twist resilient deformation structure which do not disturb both end portions of the strip-like piezoelectric elements from being vibrated and displaced.
