A light deflection device comprises a deflection member having a sphere body (71) enclosing a deflection face portion (72) for deflecting a light beam, or a segmental sphere body (1) having the deflection face portion (2) and a segmental sphere face opposing to the deflection face portion, a supporting member (73,3)for supporting the deflection member in a turnable manner, and a driving means for turning the deflection member, said driving means being provided on the sphere face (75a,b) or the segmental sphere face (7a,7b) of the deflection member, and at a position opposing to the sphere face (76a-e) or the segmental sphere face (8) of the deflection member to apply a driving force to the sphere face or the segmental sphere face. A light deflection device array comprises the arrangement of light deflection devices in one-dimensional or two-dimensional array. <IMAGE> |
