Third axis input device for a computer mouse
First Claim
1. A third axis input device for a computer mouse, comprising a fixed primary seat, a fixed secondary seat, a wheel, an annular ring-like grating member, a suspending member, and an idle roller, characterized in that:
- said fixed primary seat has a lower portion provided with a first fixed rod and a first L-shaped hook member adapted to engage with a printed circuit board, a recess between said fixed rod and said L-shaped hook member for receiving a photoelectric controller, two arms provided at two sides of said fixed primary seat for engaging with said fixed secondary seat, a vertical rod and a vertical lug extending upwardly from the top of said fixed primary seat, said lug being formed with an opening;
said fixed secondary seat includes a second fixed rod and a second L-shaped hook member having the same structure as said first fixed rod and first L-shaped hook member at the bottom rear portion, a slot at the bottom for receiving a photoelectric controller, and a hole above said slot;
said wheel is fitted on said annular ring-like grating member for facilitating operation with a forefinger;
said annular ring-like grating member is provided with an axle and a grating clearance and held between said primary and secondary fixed seats so that said annular ring-like grating member can be moved downwardly or rotated;
said suspending member is fitted over said vertical lug and said vertical rod enclosed with a helical spring for urging said annular ring-like grating member to go upwardly and turning off a power switch; and
said idle roller mounted on a top of said suspending member for supporting said annular ring-like grating member and enabling it to rotate steadily and smoothly.
