1. Field of the Invention
The invention relates to a mouse, more particularly to a wireless mouse.
2. Description of the Related Art
As a pointing device, a mouse has been widely utilized in personal computers and laptops. Recently, a wireless feature has been introduced to the mouse, such that a user can have a relatively unlimited use of the mouse. A conventional wireless mouse includes a base and a receiver connected with the computer for data transmission between the wireless mouse and the computer. Since the base and the receiver of the wireless mouse are two separate members, and since the receiver is made relatively small, storage of the receiver becomes an important issue (As addressed in Taiwanese Invention Patent No. I296770, I265445 and Taiwanese Utility Model Patent Publication No. 545648).
In another aspect, in order to provide the power needed to transmit wireless signals between the wireless mouse and the computer, the base of the mouse must be installed with a battery unit. However, since the battery unit needs to be attached firmly in the base of the wireless mouse, and detachment of the battery unit from the base due to an external force needs to be prevented, an appropriate securing mechanism for the battery unit is also needed.
