The apparatus (18) includes an applicator tip (22) using a wick (30) or roller (36).
Description
NON-DISΛPPEΛRING HIGHLIGHTER FOR OPTICALLY-SCANNED DOCUMENTS
Background of the Invention:
This invention relates to document highlighting devices and, more particularly, in a highlighting device for highlighting portions of documents including a hollow body sized to fit conveniently in a user's hand in the manner of a pen, a coating-producing medium disposed within the body, and an applicator tip located at a tip portion of the hollow body and communicating with the coating- producing medium in the body for applying a portion of the coating-producing medium to a surface of a document over which the applicator tip means is wiped, to the improvement for highlighting documents to be optically scanned in a copying process so as to prevent disappearance of highlighting or substitution of black therefor during the optical scanning comprising, the applicator tip and the coating-producing medium in combination producing a coating over the surface which appears to optical scanning apparatus as a gray, half-toned, semi-translucent area.
The highlighting of portions of documents to draw attention thereto is well known in the art. Typically, a bright colored transparent ink is applied over the portions of the document to be highlighted employing a felt- tipped marking device. Where the document is to be optically scanned as by photocopying or during facsimile transmission, there is a problem with conventional highlighting devices. Early optical scanners typically "saw" highlighting in the yellow to red portions of the spectrum as black • and simply put a black bar over the highlighted portions, rendering them unreadable. Blue portions of the spectrum simply disappeared and, therefore, so did the highlighting in the copied or facsimile transmitted document. In modern facsimile and copy machines, the most common result is that all highlighting is simply ignored during scanning regardless of the color and all highlighting disappears.
In some modern word processing systems printing on laser printers, changes made to the document are "highlighted" by a gray, half-toned, semi-translucent overprint done by the laser printer. The gray overprint, of course, appears on both photocopies and facsimile transmissions. Thus, if there were some way to hand- apply a gray, half-toned, semi-translucent "highlighter" by hand in an inexpensive manner in virtually the same way that the colored transparent highlighting is applied, the problems of disappearing highlighting in documents would be solved. Wherefore, it is the object of this invention to provide a way of hand-applying a gray, half-toned, semi-translucent coating to portions of documents by hand in an inexpensive manner in. virtually the same way that the colored transparent highlighting is applied so that the problem of disappearing highlighting in optically-scanned documents is solved.
Other objects and benefits of the invention will become apparent from the detailed description which follows hereinafter when taken in conjunction with the drawing figures which accompany it.
Summary:
The foregoing object has been achieved by the highlighting device of the present invention for highlighting portions of documents to be optically scanned in a copying process to prevent disappearance of highlighting or substitution of black therefor during the optical scanning comprising, a hollow body sized to fit conveniently in a user's hand in the manner of a pen; a coating- producing medium disposed within the body; applicator tip means located at a tip portion of the hollow body and communicating 'with the coating-producing medium in the body for receiving and applying a portion of the coating-producing medium to a surface of a document over which the applicator tip means is wiped to produce coating over the surface which appears to optical scanning apparatus as a gray, half-toned, semi-translucent area. In one embodiment, the coating-producing medium comprises a transparent liquid vehicle containing minute gray-to-black micro-
particles in homogeneous suspension and the applicator tip means comprises wick means for conducting the liquid vehicle from within the hollow body to the surface of a document without filtering the micro-particles therefrom. The preferred wick means comprises a bundle of parallel fibers contained within an outer sheath. The bundle of parallel fibers may comprise glass fibers.
In another embodiment, the coating-producing medium again comprises a transparent liquid vehicle containing minute gray-to- black micro-particles in homogeneous suspension but the applicator 0 tip means comprises highlighting roller means for conducting the liquid vehicle from within the hollow body to the surface of a document on an outer surface thereof as the highlighting roller means is rolled along the surface. In this embodiment, there may be sealing means contacting the outer surface of the highlighting s roller means as the highlighting roller means is rotated to prevent excess portions of the coating-producing medium from flowing out of the hollow body and the outer surface of the highlighting roller means may contain micro-pits therein for receiving the micro- particles therein to prevent the micro-particles from being removed o from the vehicle by the sealing means.
In still another embodiment, the coating-producing medium comprises an opaque ink and the applicator tip means comprises highlighting roller means for conducting the liquid vehicle from within the hollow body to the surface of a document on tips of a 5 plurality of minute projections carried on an outer surface of the highlighting roller. In one version, there are wick means for conducting the ink from within the hollow body to the tips of the plurality of minute projections. In another version, there are inking roller means for rotatingly applying the ink from within the hollow o body to the tips of the plurality of minute projections.

Description of the Preferred Embodiments: A highlighted portion 10 of a document 12 according to the present invention is depicted in Figure 1. The highlighting in the portion 10 comprises a gray, half-toned, semi-translucent coating 14 which is hand-applied using a highlighter 16 such as that shown in Figure 2. The highlighter 16 comprises a hollow body 18 sized to fit conveniently in the user's hand in the manner of prior art highlighters. The hollow body 18 is filled with a coating-producing medium (to be described in various embodiments shortly) which is applied to the paper 20 of the document with an applicator tip 22 extending outward therefrom. As will also be described shortly, the applicator tip 22 can be of several types according to various embodiments of the present invention.
Turning first to Figure 3, the highlighter 16 is shown in a first partially cutaway view so as to see how the applicator tip 22 communicates with the coating-producing medium 24. The medium 24 could be a semi-translucent ink producing a non-continuous coating (i.e. a half-toned coating) when applied to the paper 20.
The "ink" medium 24 in such case would be a transparent vehicle 26 containing minute gray-to-black micro-particles 28 in homogeneous suspension so as to produce the desired gray, half-toned, semi- translucent coating when applied over the surface of the paper 20 as the vehicle dries. The applicator tip 22 in that case would have to be of a non-filtering wicking material that would not filter out the micro-particles. Thus, the felt tip of the prior art highlighters would have to be replaced as it is suitable for an ink but unsuitable for this application. A bundle of parallel glass fibers 30 in an outer plastic sheath 32 would probably be the easiest and lowest cost approach and is, therefore, preferred for this embodiment.
Another approach employing the same type of medium 24 as just described is shown in Figures 4 and 5. The medium 24 comprising the transparent vehicle 26 containing minute gray-to- black micro-particles 28 in homogeneous suspension is disposed in the body 18 above a pair of plastic sealing strips 34 that ride along the surface of a highlighting roller 36 rotatably carried by the highlighter 16 at the applicator tip 22 thereof. Alternatively, sealing rollers 35 could be used in place of the strips 34, as in Figure 5. The highlighting roller 36 is of plastic and has a textured outer surface 38 containing micro-pits 40 therein into which the micro- particles 28 can fit so as to be transferred onto the paper 20 as the highlighting roller 36 rolls across the paper 20. With this embodiment and approach, the micro-particles 28 can be somewhat larger than in the wicked version described above.
Another general approach .is shown in two separate embodiments in Figures 6 and 7. In this version, the medium 24' comprises an opaque ink (preferably black or dark gray) which is applied by the tips 42 a plurality of minute projections 44 on the surface of the highlighting roller 36'. In the embodiment of Figure 6, a felt wick 46 conducts the inked medium 24' to the tips 42 of the projections 44. In the embodiment of Figure 7, an inking roller 48 performs the same function.
Thus, it can be seen that there are several embodiments of a highlighter according to the present invention for accomplishing the method of highlighting thereof of applying a gray, half-toned, semi-
translucent coating over portions of a document to be highlighted without disappearing during optical scanning for photocopy or facsimile transmission purposes. In this regard, it should be noted that the coating must be half-toned in nature as that term is understood by those skilled in the art as the optical scanning decision logic in facsimile machines, for example, looks at darkness levels of areas against a threshold value. If the black and white scanning apparatus sees "gray" over the threshold level, it is input as black. By employing a half-toned gray (i.e. dark dots separated by white) the scanning apparatus sees the dots and white as separate pixels and reproduces them in kind without seeing a totally gray area over the threshold which is then reproduced as black.
Wherefore, having thus described our invention, what is claimed is:
