Light source for bar code reader, has swinging magnet holder designed to cooperate with coil arrangement and to drive reflector, such that reflector oscillates to and fro, when coil arrangement is electrically excited

摘要

The source has an oscillating structure, which includes a housing (1) with a retaining chamber (11). An illuminant (14) is arranged in an inner side of the chamber. A reflector (2) is attached to a swiveling hole in a pivotable manner and is designed to reflect the light from the illuminant . A coil arrangement (3) is attached to a localizing part within the housing. A swinging magnet holder (22) is designed to cooperate with the coil arrangement and to drive the reflector, such that the reflector oscillates to and fro, when the coil arrangement is electrically excited.
