Abstract
The present invention provides a barcode reader, which irradiates a scanned laser beam onto a barcode symbol and reads the information written in the symbol, wherein a laser beam scanning unit is made by insertion molding as one body with a movable support member, a support member fixed to the main body, and a metallic elastic member connecting these support members, the support members are molded as one body with a scanning mirror, and a permanent magnet is fixed to the support members. A driving coil is provided in proximity to the permanent magnet, and generates an attractive force or a repulsive force to rotate the magnet at a periodic laser beam scanning angle. Further, a stopper mechanism is provided to soften an external impact to the rotation of the scanning mirror.
