Abstract
Abstract Disclosed is a palm rest with a simple structure that can be stored in a lid of an electric device. A palm rest 10 is supported rotatable at a case assembly 14 within which a keyboard 34 is mounted. By rotating the palm rest 10 outward, an operator can rest his palms on it, thus facilitating key manipulation. When the palm rest 10 is positioned upright, it is retained within a lid 18, which covers the keyboard 34. In this case, the palm rest 10 does not project outward from the PC 12 and the PC 12 can therefore be stored without difficulty. Since a gap is defined between the palm rest 10 and the front wall of the case assembly 14 when the palm rest 10 is rotated forward, a user can slip his fingers through the defined gap and grasp the palm rest 10, which then can serve as a handle for carrying the PC 12.
