Patent ID: 6917442

Claim:
An electronic pnint-board apparatus comprising: a writing medium having a writing surface where image information is written on said writing surface, reading means for reading said image information, printing means for printing said image information read by said reading means onto a printing medium, and control means for adjustably controlling driving of said reading means and driving of said printing means so that initiation of driving of said reading means being synchronous with initiation of printing of said printing means, wherein said printing means includes a transportation system for transporting said printing medium as a plurality of paper sheets to a printing section, and said transportation system includes time adjustment means for said plurality of paper sheets for allowing a printing to be initiated n synchronization with initiation of reading of said image information by said reading means, wherein said transportation system includes a paper tray for containing a stack of said plurality of paper sheets, and a feeding roller for picking up and sending out a paper sheet that forms an uppermost layer of said stack of said plurality of paper sheets, and said transportation time adjustment means includes a paper detecting sensor provided downstream of said printing section for detecting a position of a leading end of said paper sheet and a control system, in which said control system calculates time required for the paper sheet to reach said printing section from paper detection time detected by said paper detecting sensor, and pauses and reduces a speed of said feeding roller when time for initiating printing operation of said printing section is to be reached before the time for initiating reading of image information on said writing medium.
