Recognition system for tools insertable into dental treatment instruments

摘要

A recognition system is provided for tools, such as drill bits and milling bits, which are insertable into dental treatment instruments, each of the tools having an optimum speed at which the tool must be rotated for effective treatment. In the recognition system, each tool is provided with a code corresponding to the speed or speed graduation necessary to effectively use the tool. The system also includes a reader which reads the code on each tool, and generates identifying signals in accordance with the code, which are supplied to an evaluation logic. The logic converts the signal from the reader into control signals for the drive motor used to operate the tool, as well as indicator signals for visually displaying information relating to the tool currently in use.
