Abstract
The invention is to provide a rotary-type encoder structure utilized by a device to control movement and scrolling on the screen of a display, which has a resilient projecting member unitarily formed on a footing such that the resilient projecting member is postured against and between arcuate sections contiguously disposed along the inner wall of a recess in one side of a roller wheel; such that, when the user rotates the roller wheel, the coordinative relationship between the said arcuate sections and the said projecting member enables all intervals of engagement are identical during each revolution of the roller wheel to achieve the objective of page turning or movement on the screen.
Claims9
A rotary-type encoder structure comprised of:
- at least a roller wheel, a recess is hollowed out in one side of the said roller wheel and a plurality of arcuate sections are contiguously disposed along the inner wall of the said recess;
- a footing, the said footing enabling the said recess to be rotatably sleeved onto it and, furthermore, having a resilient projecting member emerging from it;
- the said resilient projecting member is unitarily formed on the said footing such that it is postured against the said arcuate sections, thereby locating the said roller wheel at relative positions;
- a shaft;
- after one extremity of the said shaft is inserted through the said footing, it is secured to the center position of the said roller wheel;
- and a turn disc is situated on the opposite extremity of the said shaft such that the said turn disc rotates synchronously along with the said roller wheel;
- as such, when the said roller wheel is rotated, the said projecting member is in a coordinative relationship with the said arcuate sections such that all intervals of engagement are identical during each revolution of the said roller wheel.
