ABSTRACT:
The present invention relates to a roller mechanism for generating a plurality of control signals, for example to scroll an image on a computer display in multiple directions. The roller mechanism has a carriage, and a roller rotatable within the carrier. The roller can drive an encoding unit to output the control signal. The carriage has a coupling portion, and the coupling portion is pivoted to a bottom support. Thus the roller and the carriage are turnable relative to the coupling portion in a fan-shaped movement while the roller is also being rotated within the carriage.
