Abstract
A mouse roller module includes a roller, a swingable rod, an adjusting assembly and a positioning track. When the swingable rod is contacted with the roller at a first location, a first interference force between the swingable rod and the roller is generated. When the swingable rod is swung to a second location, the swingable rod is contacted with the roller at a second location and a second interference force between the swingable rod and the roller is generated. The adjusting assembly includes a protrusion structure. The positioning track includes a first positioning recess and a second positioning recess. When the swingable rod is contacted with the roller at the first location, the protrusion structure is positioned in the first positioning recess. When the swingable rod is contacted with the roller at the second location, the protrusion structure is positioned in the second positioning recess.
