Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
175 words
A photocopier for the line-by-line copying of a document, comprising: a body having an upper plate; a substantially linear array of optical fibers disposed along the length of the picture-taking line; a light-proof housing disposed in said body, said housing comprising first and second lateral chambers, first and second light-proof walls separating said first and second lateral chambers, respectively, from said central chamber, a central chamber intermediate said lateral chambers, and a light-proof lateral joint disposed beneath said central chamber, said array of optical fibers being maintained in position with the upper end thereof extending laterally into the bottom of said central chamber by said lateral joint; a substantially planar plate transparent disposed in said upper plate and covering said central chamber; first and second tubular illuminating assemblies disposed in said central chamber on either side of said array of optical fibers; and first and second driving rollers disposed in said first and second lateral chambers, respectively, said rollers being insulated from said array of optical fibers and tubular illuminating assemblies by said light-proof walls.
Claim 2
Dependent Claim
175 words
A photocopier for the line-by-line copying of a document, comprising: a body having an upper plate; a substantially linear array of optical fibers disposed along the length of the picture-taking line; a light-proof housing disposed in said body, said housing comprising first and second lateral chambers, first and second light-proof walls separating said first and second lateral chambers, respectively, from said central chamber, a central chamber intermediate said lateral chambers, and a light-proof lateral joint disposed beneath said central chamber, said array of optical fibers being maintained in position with the upper end thereof extending laterally into the bottom of said central chamber by said lateral joint; a substantially planar plate transparent disposed in said upper plate and covering said central chamber; first and second tubular illuminating assemblies disposed in said central chamber on either side of said array of optical fibers; and first and second driving rollers disposed in said first and second lateral chambers, respectively, said rollers being insulated from said array of optical fibers and tubular illuminating assemblies by said light-proof walls.
Claim 3
Dependent Claim
91 words
The photocopier of claim 1, further comprising dismountable bridge means disposed above said upper plate for driving the document across said driving rollers and said transparent plate, said bridge means comprising: a cover; plaquette means attached to said cover for applying the document against said transparent plate; first and second driven rollers disposed in said cover for cooperation with said first and second driving rollers, respectively; and engagement means attached to said bridge for releasably engaging said upper plate, whereby said bridge means can be completely dismounted from said upper plate.
Claim 4
Dependent Claim
35 words
The photocopier of claim 1, further comprising first and second reflector means disposed around said first and second tubular illuminating assemblies, respectively, for orienting the light from said tubular illuminating assemblies toward said transparent plate.
