Abstract

Abstract The present invention is directed to a reader printer which handles an image of a microfilm held by an aperture card and maintained in such a manner that the microfilm center aligns with the center of card aperture. At the time of printing, the image of the microfilm is projected by scanning from a scanning start position that is same irrespective of film sizes on a photosensitive member, and the image thereon is transferred to a paper sheet which is provided by cutting the web supplied from rolled paper. The supply of the web is controlled by a first timer which starts simultaneously with start of scanning and the cutting of the web is controlled by a second timer which starts simultaneously with expiration of the first timer.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 262 words
A reader printer for handling an image of microfilm held by an aperture card and positioned in such a manner that the microfilm center aligns with the center of the card aperture, comprising; means for projecting the image of microfilm onto a screen at the time of reading or onto a photosensitive member at the time of printing, means, at the time of printing, for scanning the aperture card across a projection axis for slit manner projection from the same scanning start position for each aperture card irrespective of film size, means for supplying paper web from rolled paper, means for cutting the web supplied in a paper transporting path so as to provide a sheet paper of desired size, means for altering a magnification ratio for projecting the image of microfilm, means for selecting a paper cutting size to be cut by the web cutting means, first timer means which has a timer value in accordance with an altered magnification ratio and a selected cutting size and starts counting of the time simultaneously with the start of scanning of the microfilm, second timer means which has a timer value in accordance with a selected cutting size and starts counting of the time simultaneously with the end of counting of said first timer, and control means which controls said web supplying means and said web cutting means so that the supply of the web starts when the first timer means completes the counting of the time and the web is cut when the second timer means completes the counting of the time.
Claim 2
Dependent Claim 262 words
A reader printer for handling an image of microfilm held by an aperture card and positioned in such a manner that the microfilm center aligns with the center of the card aperture, comprising; means for projecting the image of microfilm onto a screen at the time of reading or onto a photosensitive member at the time of printing, means, at the time of printing, for scanning the aperture card across a projection axis for slit manner projection from the same scanning start position for each aperture card irrespective of film size, means for supplying paper web from rolled paper, means for cutting the web supplied in a paper transporting path so as to provide a sheet paper of desired size, means for altering a magnification ratio for projecting the image of microfilm, means for selecting a paper cutting size to be cut by the web cutting means, first timer means which has a timer value in accordance with an altered magnification ratio and a selected cutting size and starts counting of the time simultaneously with the start of scanning of the microfilm, second timer means which has a timer value in accordance with a selected cutting size and starts counting of the time simultaneously with the end of counting of said first timer, and control means which controls said web supplying means and said web cutting means so that the supply of the web starts when the first timer means completes the counting of the time and the web is cut when the second timer means completes the counting of the time.
Claim 3
Dependent Claim 27 words
A reader printer as claimed in claim 1, wherein the timer values of the first and the second timer means are variably set for compensating various errors.
Claim 4
Dependent Claim 48 words
A reader printer as claimed in claim 1, wherein the control means has a first memory which stores reference values for said first and second timer values and a second memory which stores compensating values for compensating the reference values so as to add to the reference values.
Claim 5
Dependent Claim 22 words
A reader printer as claimed in claim 3, wherein said control means further includes an input means for inputting said compensating values.
