ABSTRACT:
A pointing device includes a housing, a ball, and a cleaning member. Part of the ball protrudes from an opening of the housing. The cleaning member is pressed against the ball by a mechanism including a rod and a resilient member. The rod is made slidably movable in first and second directions. One end of the rod is connected to the cleaning member. The other end of the rod protrudes from a hole of the housing to form a button. The cleaning member is brought into contact with the ball when the button is pushed in the first direction. The resilient member forces the rod in the second direction to separate the cleaning member from the ball during normal operation.
