Abstract

Magnetic record storage unit 1 functions to store facsimile information such as engineering drawings or charts on magnetic records either in digital or analog form. The output 2 of unit 1 is supplied to an ultraviolet facsimile projector 3. This functions to convert the magnetically stored information to an ultra-violet facsimile pattern which is projected onto a belt 4. Belt 4 is coated with fulgide material. Because of one light responsive characteristic, the ultra-violet pattern, projected from 3, is stored temporarily on 4.

Magnetic record storage unit 1 functions to store facsimile information such as engineering drawings or charts on magnetic records either in digital or analog form. The output 2 of unit 1 is supplied to an ultraviolet facsimile projector 3. This functions to convert the magnetically stored information to an ultra-violet facsimile pattern which is projected onto a belt 4. Belt 4 is coated with fulgide material. Because of one light responsive characteristic, the ultra-violet pattern, projected from 3, is stored temporarily on 4.

The stored image on 4 next is subjected to yellow light from light sources 5. Because of another characteristic of fulgide material, the stored image becomes readily visible.

The portion of the now visible facsimile reproduction requiring a change is subjected to infrared radiation by means of a manually operated stylus 6. Because of a third characteristic of fulgide material, the exposed portion is erased and returns to the condition prior to exposure by the ultra-violet light pattern. Suitable corrections are then entered on the erased portion by means of a manually operated ultra-violet stylus 7.

Belt 4 is then advanced to a reading station where the corrected and updated facsimile reproduction is scanned by a facsimile scanner 8. The output 9 of scanner 8 provides either binary data signals or video-type analog signals which are stored by unit 1.

The corrected facsimile reproduction on the belt 4 is then...
