ABSTRACT:

FIELD OF THE INVENTION
The present invention relates generally to the field of electronic whiteboards and more particularly to a dry erase electronic whiteboard with a page-wide-array or board-wide-array inkjet printhead mechanism.
BACKGROUND OF THE INVENTION
Whiteboards with erasable markers for interactive discussions have widespread use in business and educational settings. There are also various types of electronic whiteboards and chalkboards available that are capable of capturing the image on the board and transferring the image to a copier. However, it would be valuable to be able to electronically put information back onto a whiteboard. For example, if a meeting, seminar or class has been suspended and resumed at a later time, it would be valuable to have the previous white board information put back on the board in order to continue the meeting or discussion. Alternatively, if a meeting must be moved to another room and reconvened, it would be advantageous to have the information on the whiteboard automatically recopied onto the whiteboard in the new meeting room. It would also be desirable for a whiteboard to be able to electronically put charts, graphs, scanned information or other electronically stored information onto the whiteboard for discussion. It would also be desirable to have a solution that is adaptable to any white board. It is possible to electronically put information on a large, flat computer screen and then store, transmit or manipulate the data. However, this is an expensive and not widely available solution.
SUMMARY OF THE INVENTION
The above and other aspects of the present invention are accomplished in a dry erase electronic whiteboard with a page-wide-array or board-wide-array inkjet printhead mechanism. Specifically, an electronic whiteboard is disclosed that is capable of scanning the surface of the whiteboard and storing the information rather than printing it out on paper. The electronic whiteboard use dry erase ink in a page-wide-array or board-wide-array inkjet printhead to put the information back onto the whiteboard at a later time. Alternatively, the electronic whiteboard may send the information to another electronic whiteboard, to a storage device, such as a floppy disk or a CD to be retrieved later by the same or a different electronic whiteboard and put back onto the whiteboard with dry erase ink by a board-wide-array inkjet printhead. Still further, the electronic whiteboard may electronically receive stored information from a computer, a fax, a floppy disk, a CD or other known means and electronically put the received information onto the whiteboard using dry erase ink by means of a board-wide-array inlet printhead. The electronic whiteboard scanner/inkjet printer head of the present invention may also be portable and usable with any standard whiteboard.
