Abstract
A roller module for an input module includes a roller base, a roller element and an adjusting element. The roller element is pivotally coupled to the roller base. Moreover, at least one discontinuous protrusion structure is circumferentially arranged a bottom surface of a concave region of the roller element. A contacting part of the adjusting element is contacted with the at least one discontinuous protrusion structure. Consequently, a rotation of the roller element results in a tactile feel.
Claims12
A roller module for an input device, the roller module comprising:
- a roller base;
- a roller element comprising a concave region and a fixing shaft, wherein the fixing shaft is partially disposed within the concave region and pivotally coupled to the roller base, and at least one discontinuous protrusion structure is circumferentially arranged at a bottom surface of the concave region;
- and an adjusting element comprising a contacting part and an operating part, wherein the operating part is connected with the contacting part, wherein the contacting part is contacted with the at least one discontinuous protrusion structure, so that a rotation of the roller element results in a tactile feel, wherein the at least one discontinuous protrusion structure includes a first discontinuous protrusion structure, a second discontinuous protrusion structure and a third discontinuous protrusion structure, wherein the first discontinuous protrusion structure is circumferentially arranged around the fixing shaft, the second discontinuous protrusion structure is circumferentially arranged around the first discontinuous protrusion structure, and the third discontinuous protrusion structure is circumferentially arranged around the second discontinuous protrusion structure.
