Abstract
Abstract A fiber optics element for picking up light reflected by a subject copy which is disposed closely adjacent to the one face thereof, said fiber optics element comprising a first fiber plate formed of a plurality of optical fibers through which the incoming light is conducted to said subject copy, a second fiber plate formed of like optical fibers through which the light reflected by said subject copy is conducted in a direction different from that of said incoming light and a reflector means for reflecting said light conducted by said second fiber plate to provide a light output modulated by said subject copy.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
50 words
A fiber optics element according to claim 1, wherein said cut surface is formed at an angle of 45* to said fiber axes and the numerical aperture of the optical fibers of said second fiber plate is substantially larger than that of the optical fibers of said first fiber plate.
Claim 2
Dependent Claim
36 words
A fiber optics element according to claim 1, further comprising a transparent filler member which is interposed in the triangular notch between said full reflector means and said inner end face of said second fiber plate.
Claim 3
Dependent Claim
70 words
A fiber optics element according to claim 1, wherein a second cut surface and full reflector means are provided on the opposite side surface of said first fiber plate, with a third smaller fiber plate, to define a symmetrical arrangement with at least a central row of optical fibers of said fIrst fiber plate extending continuously between the end faces of said fiber optics element for illuminating the subject copy.
