Abstract
A slender wheel mouse includes a mouse case, a base, a circuit board, a supporting member, a tilt frame, a slender wheel, an encoder, a slender ratchet, a resilience sheet and several switch elements. The slender ratchet is engaged with the slender wheel to drive the encoder. The slender wheel has a relatively smaller diameter and thus the height of the mouse case is reduced.

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;
- 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.
