Abstract:
1. A slender wheel mouse comprising: a base; a circuit board disposed on said base; a supporting member disposed on said base and movable upwardly or downwardly with respect to said base, wherein said supporting member comprises: a first protrusion inserted into said first fixing plate gliding groove; a second protrusion inserted into said second fixing plate aperture; and a third protrusion inserted into said third fixing plate aperture, wherein said supporting member is movable upwardly or downwardly with respect to said base by using said second protrusion and third protrusion as a shaft and gliding said first protrusion along said first fixing plate gliding groove, and wherein said base further comprises a first fixing plate, a second fixing plate and a third fixing plate, which are penetrated through corresponding perforations of said circuit board and connected with said supporting member, wherein said first fixing plate has a first fixing plate gliding groove, said second fixing plate has a second fixing plate aperture, and said third fixing plate has a third fixing plate aperture; a tilt frame disposed on said supporting member and tiltable with respect to said supporting member; a slender wheel disposed on said tilt frame and having multiple saw-toothed structures formed on a surface thereof; an encoder disposed on said circuit board and beside said supporting member; a slender ratchet having multiple ratchet pawls, wherein a first end of said slender ratchet is inserted into said encoder; and a resilience sheet disposed on said supporting member, wherein said resilience sheet is sustained against said slender ratchet such that said ratchet pawls are engaged with said saw-toothed structures and said slender ratchet is rotated with said slender wheel.
