Patent ID: 8276447

Claim:
A balancing machine for balancing vehicle wheels, comprising a supporting structure for supporting grip and rotation means for gripping and rotating a wheel to be balanced, detection means for detecting the unbalance of the wheel during rotation, at least a processing unit which is operatively associated to said grip and rotation means and to said detection means, at least a screen which is associated to said supporting structure and which is operatively associated to said processing unit and adapted to display the detected unbalance data and selection functions or lists of functions, and at least a control panel for the selection of said functions or lists of functions having at least a touch-screen control surface, wherein said machine comprises control means for controlling the operation of said control surface between a continuous operating mode, in which the touching of said control surface without removing one's finger between two positions leads to scrolling on said screen between said functions or lists of functions, and a discrete operating mode, in which on said control surface is determined at least a discrete portion and the touching of said discrete portion with a finger leads to the selection of one of said functions or lists of functions, said control means being able to dynamically associate said discrete portion with a respective function or list of functions represented graphically on said screen and to dynamically determine the perimeter and the position of said discrete portion or said control surface, according to a particular graphic interface displayed on said screen, so as to reproduce the position of the functions of list of functions graphically represented on said screen.
