Abstract:
A digital camera with a lens being automatically retractable and an automatic retraction method thereof are provided. After the digital camera is turned on, it can continuously capture images from the outside at a predetermined time interval, and convert the images into corresponding image characteristic values and then compare them. When the characteristic values of the current image differ from the previous one and reach a predetermined difference, the lens exposed outside is automatically retracted, so as to reduce damage to the lens due to falling or heavy shaking of the digital camera.

The circuit board body includes at least one stuck part, wherein the stuck part is disposed along the edge of the circuit board body and corresponds to the fixing part; further, the stuck part recesses inwards into the circuit board body to form a U shape. One end of the adjusting component movably penetrates the fixing part and being screw locked thereon, and another end of the adjusting component is embedded to the stuck part.
Abstract:
A focus adjustment mechanism is used for a photo device for adjusting a focus of a lens assembly of the photo device. The focus adjustment mechanism comprises a focus adjustment button connected to a casing of the photo device and comprising a contact portion, and a pressure detection module disposed in the photo device in a position corresponding to the focus adjustment button to contact the contact portion, and the pressure detection module is electrically coupled with the lens assembly. When the focus adjustment button is pressed, the pressure detection module can generate a signal value according to a displacement value of the focus adjustment button so that a focus of the lens assembly is determined according to each signal value. Furthermore, the present invention discloses a photo device having the focus adjustment mechanism.
Abstract:
The present invention discloses a touch screen comprising a flexible print circuit board, an electrically conducting layer, and a flexible control board. The flexible print circuit board has a functional plane, and the functional plane comprises a plurality of electrically conducting areas. Each of the electrically conducting areas is capable of transmitting a corresponding signal when conducted. The electrically conducting layer is disposed on the functional plane of the flexible print circuit board. The flexible control board covers on the conducting layer and comprises a plurality of pressing areas, wherein each of the pressing areas corresponds to one of the conducting areas. By pressing any of the pressing areas, the corresponding electrically conducting area on the flexible print circuit board is conducted, so the conducted electrically conducting area transmits the corresponding signal.
Abstract:
A key button is provided for pressing against a metal dome to trigger a signal. The key button structure includes a button cap and a button stem. One tip end of the button stem is in a shape of spherical camber which is in point contact with the metal dome, so that the button stem, when being pressed, is within an effective pressing area of the metal dome to prevent the metal from being permanently deformed and damaged.
