Develops Technology to Make Dot Images That Denshi-Pen Reads Invisible

TOKYO, April 23, 2012 –Fuji Xerox Co., Ltd. has developed a technology^Note1 to make dot images on paper exclusive for use with Denshi-Pen (Photo 1) invisible.

Denshi-Pen is a hand-written information input system consisting of pen and paper, which easily and swiftly converts handwriting on paper into digital data. With this system, position information and other data are coded in dot images that are printed in advance on paper. The Denshi-Pen uses a tiny camera mounted on its tip to take pictures of the dot images and reads the coded data as text is hand-written on the paper. Previously, the dot images were printed on paper with ink containing carbon black, making the entire paper look gray.

Developed proprietary color material that is invisible to the human eye but can be read by the Denshi-Pen

Utilizing the material technology for xerographic photoreceptors that Fuji Xerox has nurtured over many years, the company has developed an infrared-absorbing color material that is not easily visible to the human eye due to having no absorption in the visible region. However, it can be read with the camera installed on tip of the pen. Paper printed with the ink based on this near-transparent infrared-absorbing material does not produce the overall gray appearance, making the paper look as clean as white plain paper and making hand-written characters easy to read (Photo 2).

Starting April 24, Fuji Xerox will give an offer of a free Denshi-Pen Standard Notebook White (B5) pad, applied with the new technology to the first 700 people who newly purchase a Denshi-Pen 1 JS. See the website below on how to apply.

Denshi-Pen consists of pen and paper, which are common tools that anyone is familiar with. The system easily and swiftly digitizes handwritten information without changing the style of writing on paper, which is required in situations such as work at clients' sites, outdoors, at factories and at other locations where a computer may not be brought in.
