Abstract: An electronic device is provided, including a main body and a camera module. The camera module has a frame, a lens unit disposed in the frame, a guiding member, and a hinge. The guiding member is affixed to the main body and has a rail and a spring sheet. The hinge pivotally connects to the frame and the guiding member. When the camera module is in the retracted position, the camera module is hidden in a recess of the main body. When the camera module slides out of the recess from the retracted position along the rail into the operational position, the spring sheet is pressed by the hinge to increase the friction between the hinge and the guiding member.

Abstract: The present invention provides a gel polish composition characterized by containing no irritating reactive (meth)acrylate monomer, such as hydroxyethylmethacrylate (HEMA) and ethyl methacrylate (EMA). In the present invention, the gel polish composition comprises at least an aliphatic urethane acrylate oligomer, a polyester acrylate oligomer, a low-irritating acrylate monomer, and a photoinitiator. The gel polish composition possesses low or no irritating effects to skin, exhibits excellent adhesiveness to nails, and is stable in long-term storage at ordinary shelf conditions.

Abstract: The present invention discloses a nail gel solidification apparatus including a housing, a control circuit board, a plurality of reflecting lamp holders, a plurality of light emitting diode (LED) elements and a power supply module. By replacing the traditional lamp with the LED elements of the reflecting lamp holders, the invention provides longer using life and lower power consumption and reduces the solidification time for nail gels.
