Abstract

Abstract This invention provides a unique system for capturing the image of a cathode ray tube (CRT) and transferring it to a copier machine. Cathode ray tubes have many uses, one being part of a terminal device for a computer, another being the screen of an oscilloscope and one other being part of a television set. Sometimes a permanent image is desired of what is displayed on a CRT. This is often referred to as a hard copy. This invention provides for the transfer of the image displayed on the CRT screen to a copier machine.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 122 words
An image display and recording system comprising: A. a terminal including a cathode ray tube adapted to display visual intelligence on the front face of a fluorescent screen which may be observed within a predetermined viewing area, said tube being provided with an envelope having an optical assembly thereon affording a view of the mirror image of the display appearing on the rear face of the screen, B. a copier device for making copies of the mirror image without interfering with front face observation of the display, said device being installed at a position displaced from said viewing area; and C. image-transmission means linking said optical assembly with said copier device to transfer said image thereto, whereby copies thereof may be made.
Claim 2
Dependent Claim 122 words
An image display and recording system comprising: A. a terminal including a cathode ray tube adapted to display visual intelligence on the front face of a fluorescent screen which may be observed within a predetermined viewing area, said tube being provided with an envelope having an optical assembly thereon affording a view of the mirror image of the display appearing on the rear face of the screen, B. a copier device for making copies of the mirror image without interfering with front face observation of the display, said device being installed at a position displaced from said viewing area; and C. image-transmission means linking said optical assembly with said copier device to transfer said image thereto, whereby copies thereof may be made.
Claim 3
Dependent Claim 18 words
A system as set forth in claim 1, wherein said copier device is an electrostatic dry copier machine.
Claim 4
Dependent Claim 35 words
A system as set forth in claim 1, wherein said image-transmission means is constituted by an arrangement of crystal wedges to deflect the image along a path from the optical assembly to the copier device.
