ABSTRACT:
A compact flying printer has a continuously rotating print drum and ratchet wheel, a trigger lever positionable to be struck by a tooth of said ratchet wheel and a hammer lever driven by said trigger lever and provided with a print hammer at its end. The trigger lever is formed with a linear guide portion for regulating the motion thereof and an energy-transmitting portion projected for transmitting energy from said ratchet wheel to said hammer level. Paper and ribbon are advanced by selective coupling of a transmitting member to a continuously rotating rotor operated in conjunction with the print drum.
