Abstract
A roller structure for input devices with improvement is disclosed. The roller structure of the present invention comprises a roller, a supporting seat, an encoder, a circuit board, a contact switch and a roller supporting seat. The supporting seat is disposed within the roller, and a space is provided on one side of the supporting seat so that the encoder is fixedly disposed in the space and hence the roller structure has a smaller size. A contact switch is provided on the circuit board. Two positioning protrusions are provided on the outside of the supporting seat and two positioning tracks are provided on the roller supporting seat so that the movement of the supporting seat may be guided and limited by the roller supporting seat. An activation protrusion is provided on the two positioning protrusions and may activate the contact switch when the supporting seat is pressed down.
