Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 296 words
A document processing and printing apparatus having a main body frame, comprising: an input unit for inputting character data and control commands; an external storage unit; a display unit; a print-output unit; and a control circuit unit for editing document data on the basis of inputs supplied from said input unit, for making said external storage store the data therein, for making said display unit display the data thereof and for making said print-output unit perform printing; wherein in said apparatus, said external storage unit, said display unit and said print-output unit are integrally combined together and incorporated in said main body frame; wherein said main body frame includes a top surface providing a generally horizontal, flat first paper supply guide surface; wherein said print-output unit includes pairs of paper supply rollers disposed at the rear of said first paper supply guide surface, each pair of said paper supply rollers defining therebetween a paper supply plane flush with said first paper supply guide surface, a flat platen juxtaposed with said pairs of paper supply rollers and directed upwards, said flat platen having an upper surface flush with said first paper supply guide surface, a paper supply guide plate tiltably disposed at the rear of said first paper supply guide surface a having an upper surface which guides recording paper, wherein said upper surface of said paper supply guide plate defines a second paper supply guide surface flush with said first paper supply guide surface, and a carriage mechanism and a recording head carried by said carriage mechanism and disposed above said flat platen and directed downward to face said flat platen, said carriage mechanism moving said recording head along said flat platen, and means interposing an ink ribbon between said flat platen and said recording head.
