ABSTRACT:
A computer mouse includes an upper cover and a chassis. The upper cover and the key assembly are made with one-piece construction. The upper cover and the chassis are separately provided with a buckle and fastener mechanism for connecting those two elements together. By this arrangement, the upper cover can be readily attached to the chassis without applying screws or similar fasteners. A Y-shape slot is provided at the encoding wheel supporter for easy mounting of the encoding wheel and adding lubricant. The skidding pads are provided with ratchet hookers to readily attach to the mounting holes of the chassis. The roller is mounted on a U-shaped elastic sheet for providing a biasing force to the tracing ball. The roller mechanism can be readily mounted on the roller bracket of the chassis.
