Patent ID: 7212324

Claim:
An optical scanning arrangement including adjustment means for adjusting a scanning position of a scanning beam from optical scanning means, the adjustment means adjusting a position of a curved mirror for reflecting the scanning beam and guiding the scanning beam thus reflected to a scanning target, so as to adjust the scanning position of the scanning beam, and including first adjustment means for carrying out coarse adjustment in the position of the curved mirror and second adjustment means for carrying out fine adjustment in the position of the curved mirror, the first adjustment means moving the curved mirror linearly in substantially vertical and parallel directions with respect to an approximately plane surface of a part where the scanning beam can be incident in a reflective surface of the curved mirror, so as to carry out the coarse adjustment in the position of the curved mirror, the second adjustment means moving the curved mirror linearly only in a substantially parallel direction with respect to the approximately plane surface after the first adjustment means have completed the coarse adjustment, so as to carry out the fine adjustment in the position of the curved mirror.
