Patent ID: 8665589

Claim:
A peripheral input device capable of carrying a tabular electronic device, the tabular electronic device having a bottom and a back casing, the peripheral input device comprising: a base having a surface; an inputting module disposed on the surface for allowing a user input data to the tabular electronic device; a supporting mechanism comprising a first support and a slip stopper, a first lower end portion of the first support being pivotally connected to the base, a first upper end portion of the first support being pivotally connected to the slip stopper, such that the slip stopper is capable of rotating on the first upper end portion, the slip stopper having a designated contact surface; and a retaining structure disposed between the inputting module and the supporting mechanism; wherein when the bottom of the tabular electronic device is retained by the retaining structure, and the first support is lifted by pivoting upward on the first lower end portion, the slip stopper is rotated to fit an inclination angle of the back casing so that the slip stopper keeps contacting the back casing through the designated contact surface when the inclination angle of the back casing changes, and the first support and the tabular electronic device form a reverse V-shaped structure to support the tabular electronic device stably.
