Abstract

A bar code scanner with small size has the features: 1. bendable component with one cantilevel side end supported on the platform; 2. scanning mirror installed on the bendable component; 3. scanning beam generator for guiding the scanning mirror; 4. device for receiving the reflective light from the scanned bar code and generating electric signal corresponding to the reflective light; 5. permanent magnet installed on the bendable component; 6. driving coil positioned beside the permanent magnet, applied exteranl driving signal with peridic changes, then induced by the periodic magnetic field to vibrate the bendable component in the frequency of driving signal with peodic change, then generating scanning beam.
