Abstract
Abstract A light deflector comprising a rotating member provided with at least one light transmitting means having an input terminal and an output terminal. In this light deflector, with the rotation of the rotating member, a light beam put into the light transmitting means from the input terminal exits from the output terminal as a light beam to be rotatingly scanned about the rotating axis of the rotating member as a center.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
94 words
A light deflector comprising a two-stage cylindrical rotating member having a small diameter portion and a large diameter portion and including at least one light transmitting member, each light transmitting member having an input terminal located on the peripheral side surface of said small diameter portion and a corresponding output terminal located on the peripheral side surface of said large diameter portion such that when said rotating member rotates, a light beam, entering an input terminal exits from the corresponding output terminal, and is rotatingly scanned about the rotating axis of the rotating member.
Claim 2
Dependent Claim
94 words
A light deflector comprising a two-stage cylindrical rotating member having a small diameter portion and a large diameter portion and including at least one light transmitting member, each light transmitting member having an input terminal located on the peripheral side surface of said small diameter portion and a corresponding output terminal located on the peripheral side surface of said large diameter portion such that when said rotating member rotates, a light beam, entering an input terminal exits from the corresponding output terminal, and is rotatingly scanned about the rotating axis of the rotating member.
Claim 3
Dependent Claim
27 words
The light deflector of claim 1 wherein the light transmitting member comprises an optical fiber adjacent said input terminal and a rod lens adjacent said output terminal.
Claim 4
Dependent Claim
33 words
The light deflector of claim 1 or 2 wherein the rotating member is provided with a plurality of light transmitting members having their input terminals and output terminals disposed at predetermined angular intervals.
Claim 5
Dependent Claim
64 words
The light deflector of claim 1 or 2 wherein the rotating member is provided with a plurality of light transmitting members having their input terminals disposed at the same angular position at predetermined intervals in the direction of the rotating axis of the rotating member and their output terminals disposed at the same angular position at intervals in the direction of the rotating axis.
Claim 6
Dependent Claim
30 words
The light deflector of claim 1 or 2 wherein the input terminal and the output terminal of each of said light transmitting members are disposed at the same angular position.
