Abstract
A pen type recording device for recording data in any of several colors has a carriage having a rotary drum and movable across the surface of the recording paper through a printing region and a pen-selecting region. The rotary drum carries a plurality of pens arranged on its periphery and cam means mounted on the rotary drum and provided with feed teeth adapted to engage a stationary projection in such a manner that when the carriage is in the printing region, the rotary drum cannot rotate and when the carriage is in the pen-selecting region, the drum can be rotated by reciprocating the carriage to bring a selected pen into printing position.
