Patent ID: 7940442

Claim:
An optical scanning device comprising: first control means for controlling a light source to adjust conditions for emission of an optical signal emitted by said light source; a light transmission mechanism adapted to receive the optical signal emitted by said light source, allows the received optical signal to pass therethrough, and emerges it as a scanning optical signal, said light transmission mechanism being also adapted to serve to vary an angle of deviation in response to an input of predetermined control information, the angle of deviation being an angle formed between the incident optical signal entering said light transmission mechanism and the scanning optical signal which emerges from said light transmission mechanism; and second control means for use in providing the control information to said light transmission mechanism, wherein said light transmission mechanism includes a light transmission member adapted to deform, according to an external force, at least one of a face on which the optical signal is incident, and another face from which the scanning optical signal emerges, thereby to vary an angle of incidence of the laser beam or an angle of output of the laser beam; and a driving mechanism for use in applying the external force to the light transmission member.
