Abstract:
An improved scanning apparatus for use in a barcode device, comprising:a twist means including a formed member and a holding beam mounted on the formed member, the holding beam having a reflection element located thereon and two ends each having a recess, each recess having a magnetic element disposed therein; and a driving means located at two sides of the twist means; wherein the formed member is made from a material of high elasticity coefficient selected from the group consisting of silicon rubber and rubber, said formed member being arranged to twist upon application of a corresponding force resulting from interaction between the magnetic elements and a magnetic force generated by the driving means when the driving means is magnetized, and to move the reflection element concentrically as a result of a counter reaction force and the inertia of the formed member when the magnetic force is absent for projecting light to a barcode of an object to be scanned.
