Abstract:
1. A mode-switching device of a control panel for use in an electronic apparatus, said control panel comprising a control region having a first area and a second area, said mode-switching device being operated to control the operating status of said control panel to be switched between a first operating mode and a second operating mode, said mode-switching device comprising: a foldable plate disposed above said control panel and arranged on said control region between said first area and said second area, said foldable plate including a rotating shaft and a rotating arm, said rotating arm having a cam adjacent to a connecting portion between said rotating shaft and said rotating arm, said cam having a first arc surface, a second arc surface and a rotating center, wherein a first distance between said first arc surface and said rotating center is less than a second distance between said second arc surface and said rotating center; a triggering element disposed under said cam and beneath said control panel, said triggering element being partially exposed relative to said control panel; and a switch device disposed on a control circuit board and under said triggering element, wherein said control panel is operated in said first operating mode when said rotating arm of said foldable plate lies on said first area such that said cam is separated from said triggering element, and said foldable plate is rotated along said rotating shaft to cause said rotating arm to lie on said second area such that said second arc surface of said cam is directly sustained against said triggering element to move said triggering element downwardly to activate said switch device, thereby controlling the operating status of said control panel from said first operating mode to said second operating mode.
