Abstract

Abstract This invention relates to a copying apparatus comprising a housing having therein a reflex exposure means, a bridge-like glass fiber optic, means for moving an optically clear spacing film together with copying material past one end of the fiber optic, and means for moving an optically clear spacing film together with a master past the other end of the fiber optic and in a direction opposite to that of the copying material.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 84 words
A copying apparatus comprising a housing having therein a reflex exposure means, a bridge-like glass fiber optic, means for moving an optically clear spacing film together with copying material past one end of the fiber optic, and means for moving an optically clear spacing film together with a master past the other end of the fiber optic and in a direction opposite to that of the copying material, said spacing films being located intermediate said copying material and master, respectively, and said fiber optic.
Claim 2
Dependent Claim 84 words
A copying apparatus comprising a housing having therein a reflex exposure means, a bridge-like glass fiber optic, means for moving an optically clear spacing film together with copying material past one end of the fiber optic, and means for moving an optically clear spacing film together with a master past the other end of the fiber optic and in a direction opposite to that of the copying material, said spacing films being located intermediate said copying material and master, respectively, and said fiber optic.
Claim 3
Dependent Claim 26 words
A copying apparatus according to claim 1 in which the exposure means includes a light source mounted at an acute angle to the plane of exposure.
Claim 4
Dependent Claim 21 words
A copying apparatus according to claim 2 including a deflecting mirror mounted in the path of rays from the light source.
Claim 5
Dependent Claim 17 words
A copying apparatus according to claim 1 in which a single optically clear spacing film is employed.
Claim 6
Dependent Claim 18 words
A copying apparatus according to claim 1 in which a pair of optically clear spacing films is employed.
Claim 7
Dependent Claim 28 words
A copying apparatus according to claim 1 including means for the application of an oil film between the spacing films and the glass fiber optic in contact therewith.
Claim 8
Dependent Claim 24 words
A copying apparatus according to claim 1 including roller means for ensuring that the films are stretched only horizontally when adjacent the fiber optic.
Claim 9
Dependent Claim 29 words
A copying apparatus according to claim 1 including a sufficient supply of optically clear spacing film to ensure a repeated transfer between a wind-off reel and a wind-up reel.
Claim 10
Independent Claim 78 words
A method of copying which comprises moving an optically clear spacing film together with copying material past one end of a bridge-like glass fiber optic, and moving an optically clear spacing film together with a master past the other end of the fiber optic in a direction opposite to that of the copying material while exposing the master to a light source, said spacing films being located intermediate said copying material and master, respectively, and said fiber optic.
Claim 11
Independent Claim 78 words
A method of copying which comprises moving an optically clear spacing film together with copying material past one end of a bridge-like glass fiber optic, and moving an optically clear spacing film together with a master past the other end of the fiber optic in a direction opposite to that of the copying material while exposing the master to a light source, said spacing films being located intermediate said copying material and master, respectively, and said fiber optic.
