BACKGROUND OF THE INVENTION In general, this invention relates to a printing transfer and display arrangement incorporating a continuous removing transfer band onto which there is formed a transferable image, and more particularly to an arrangement that includes a secondary transfer band having means for visual display and means for producing a permanent record copy.
The prior art as indicated'in the above-identified crossreferences provides transfer band means from which there is produced the permanent record copy. According to the invention described herein, there is the incorporated visual display which permits the use of the transfer band concept with large volume information communications systems, where only a selected fraction of the incoming information need be preserved as a permanent record. Therefore, this arrangement develops further the concepts and features presented in the above-identified applications.
SUMMARY OF THE INVENTION It is an object of this invention to provide a printing transfer band arrangement which includes means for visual display and means for producing a permanent record copy of the image produced on a continuously moving primary transfer band.
It is another object of this invention to provide a secondary transfer band onto which the image produced on said primary transfer band is transferred for visual display and subsequent printout of the image.
According to the broader aspects of this invention, there is provided a primary transfer band onto which, at an image forming station, there is formed a transferable image, a secondary transfer band movable in a traverse direction to said primary band, a transfer station having means for transferring the image from said primary band to said secondary band, and a print station including means for causing the printout of said transferred image on a permanent record copy.
BRIEF DESCRIPTION OF THE DRAWING The following description will be more clearly understood by reference to the sole accompanying drawings which illustrates the printing transfer band and display arrangement according to the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the accompanying drawing, a printing transfer band display arrangement according to the invention is shown. The primary transfer band 11 is mounted on a pair of rollers 12, one or both of which may be powered to provide the motion for the continuous loop. An image forming station 13 forms a transferable image 14 on a continuously moving band.
The image forming station 13 may be one of the arrangements as disclosed in the above-identified reference US. Pat. No. 3,477,368. The image 14 is carried on the primary transfer band to a transfer station 15, wherein the image 14 is transferred onto a secondary band 16 by means of an electrostatic or magnetic field station 17. Normally, as described in the above-identified cross-references, the image 14 is transferred across a gap existing between the primary transfer band and the secondary transfer band 16 due to excitation of the electrostatic or magnetic field station 17 as described in said referenced patent.
The secondary transfer band 16 1S transversely movable in relation to said primary transfer band and is mounted on rollers 18, one or all of which may be powered to supply the motion for the secondary band. The band 16 is a transparent band and when it reaches display position 19, it forms a suitable surface for the visual display of image 14.
The transfer band continues on its course until the image 14 reaches the print station 20, wherein the print field generator 21 comprising two plates connected to positive and negative sources of potential, is excited when the image 14 is positioned at the proper location opposite a permanent copy media 22. The excitation of the generator plates creates a magnetic field to cause the transfer of the image from the secondary transfer band 16 to the copy media 22 to form the permanent record copy. The transfer of the image 14 from the band 16 to media 22 may also occur across a gap between the copy media 22 and the band 16.
The above described arrangement shows a method in which an image placed on a continuous looped transfer band 11 is transferred onto another continuously looped transparent band 16 which may also be used to serve as a visual display at position 19, and thereafter to produce a permanent record from the image 14 which has been displayed, or to reproduce in permanent record form any desired part of the image.
While 1 have described above the principle of my invention in connection with specific apparatus, it is to be clearly understood that this description is made only by way of example and not as a limitation to thescope of my invention, as set forth in the objects thereof and in the a accompanying claims.
1, A printing arrangement comprising:
A primary transfer band mounted on a pair of rollers and formed in a continuous loop, said primary band having formed thereon a transferable image;
a secondary transparent transfer band mounted on at least three rollers and movable in a traverse direction to said primary band and in a continuous triangular loop;
a transfer station located adjacent one leg of said triangular loop, said transfer station including means for creating a magnetic field for transferring said image from said primary band onto the interior surface of said triangular loop;
a print station located on a second leg of said triangular loop, said print station including means for generating a magnetic field and causing said image to be transferred onto a copy media; and
a visual display position located adjacent said one leg and between said transfer and print station, whereby the transferred image is in a proper position for direct viewing on the outer surface of said transparent band.
