ABSTRACT:
A scanning arrangement for use in an optical scanner, for example a bar code scanner, comprises an optical element which is mounted for oscillation in two directions to produce a two dimensional scanning pattern. The optical element is preferably relatively light, and is mounted for oscillatory motion in an x direction by the flexing of a spring of relatively high modulus of elasticity. The spring is secured to a mounting bracket which itself is mounted to a stationary frame by a further spring which is arranged to flex and cause oscillation in the y direction. The mounting bracket is relatively heavy in comparison with the mirror, and the second spring has a relatively low modulus of elasticity, thereby producing a y oscillation which is slower than the x oscillation.
