摘要

#CMT# #/CMT# The mouse (2) has a housing (20) including a receptacle (23) with an entrance (23`) exposed from the housing. A rubbery cover (21) closes the receptacle when the cover is plugged into the entrance. The cover has a post (211) extended from a surface facing to the entrance. A tip portion of the post is formed as a bulge (212). An indentation (201) is formed in a bottom surface of the receptacle corresponding to the bulge that is embedded into the indentation. A recess structure (202) of the housing proximates the entrance. A wireless signal receiver (22) is accommodated within the receptacle. #CMT#USE : #/CMT# Wireless mouse for use as an input device of a computer system, and for storing a wireless signal receiver within a main body of the mouse. #CMT#ADVANTAGE : #/CMT# The indentation is formed in the bottom surface of the receptacle corresponding to the bulge that is embedded into the indentation, thus preventing detachment of the rubbery cover from the housing when the cover is plugged into the entrance of the receptacle. The mouse allows the user to easily pull and open the rubbery cover by placing a finger into the recess structure, and reduces the cost of the mouse. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded view of a wireless mouse. 2 : Wireless mouse 20 : Housing 21 : Rubbery cover 22 : Wireless signal receiver 23 : Receptacle 23` : Entrance 201 : Indentation 202 : Recess structure 211 : Post 212 : Bulge.
