Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
196 words
A microfiche viewer and copier comprising in combination: a microfiche viewing system having optical projecting means and means for identifying a desired microfiche card and frame and selecting the desired card from a library and positioning said card in said projection means to project an image of the desired frame on a viewing screen; an optical image copier having a copying cycle of operation for copying images projected thereto; means in said optical projection means for projecting images to said copier; selectively actuatable means for activating said copier; and control means actuated by the copying cycle of the copier for effecting the copying of a desired sequence of successive frames on said microfiche card; said control means comprising a counter means, means for injecting a first frame identification count in said counter means, means for generating signals in response to the copying cycle of the copier for advancing the frame identification count in the counter means, and means for coupling the frame identification count in the counter means to said frame identifying and positioning means to effect successive positioning of frames in said projection means in correspondence with the frame identification count in said counter means.
Claim 2
Dependent Claim
196 words
A microfiche viewer and copier comprising in combination: a microfiche viewing system having optical projecting means and means for identifying a desired microfiche card and frame and selecting the desired card from a library and positioning said card in said projection means to project an image of the desired frame on a viewing screen; an optical image copier having a copying cycle of operation for copying images projected thereto; means in said optical projection means for projecting images to said copier; selectively actuatable means for activating said copier; and control means actuated by the copying cycle of the copier for effecting the copying of a desired sequence of successive frames on said microfiche card; said control means comprising a counter means, means for injecting a first frame identification count in said counter means, means for generating signals in response to the copying cycle of the copier for advancing the frame identification count in the counter means, and means for coupling the frame identification count in the counter means to said frame identifying and positioning means to effect successive positioning of frames in said projection means in correspondence with the frame identification count in said counter means.
Claim 3
Dependent Claim
61 words
A microfiche viewer and copier as set forth in claim 1, wherein said control means further comprises means for establishing a last frame identification count, means for continually comparing the frame identification count in the counter means for correspondence with the last frame identification count, and means responsive to such correspondence cooperating with said selectively actuatable means to deactivate said copier.
Claim 4
Dependent Claim
56 words
A microfiche viewer and copier as set forth in claim 2, wherein said means in said optical projection means is a mirror moveable between a first position for projecting an image to said screen and a second position for projecting an image to said copier, and said selectively actuatable means includes means for driving said mirror.
Claim 5
Dependent Claim
54 words
A microfiche viewer as set forth in claim 1, wherein said means in said optical projection means is a mirror moveable between a first position for projecting an image to said screen and a second position for projecting an image to said copier, and said selectively actuatable means includes means for driving said mirror.
