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 lever.
Claims11
In a printing device having printing means, drive means for said printing means, and means for incrementally, longitudinally advancing an inked ribbon relative to said printing means, the improvement in said ribbon advancing means which comprises a continuously rotating member driven by said drive means;
- a transmitting member displaceable between a first rest position and a second position;
- first coupling means selectively operably engaging said transmitting member and said rotating member for the selective displacement of said transmitting member between said first and second positions in response to the rotation of said rotating member;
- spring means coupled to said transmitting member for the storage of energy during the displacement thereof between said first and second positions;
- means disengaging said transmitting member and said rotating member at said second position to release said transmitting member for return to said first position in response to the energy stored in said spring means;
- ribbon engaging means;
- and second coupling means operably engaging said transmitting means and said ribbon engaging means during said displacement of said transmitting member for operative displacement of said ribbon advancing means.
A printing device having printing means, continuously rotating drive means for said printing means, and means for supporting an inked ribbon in registration with said printing means, the improvement in said printing device which comprises a continuously rotating member driven by said drive means;
- a transmitting member displaceable between a first rest position and a second position;
- first coupling means selectively operably engaging said transmitting member and said rotating member for the selective displacement of said transmitting member between said first and second positions in response to the rotation of said rotating member;
- first spring means coupled to said transmitting member for the storage of energy during the displacement thereof between said first and second positions;
- means disengaging said transmitting member and said rotating member at said second position to release said transmitting member for return to said first position in response to the energy stored in said spring means;
- means pivotably mounting said ribbon support means for displacement between first and second positions representative of two laterally shifted positions of said ribbon;
- second spring means biasing said ribbon support means in its second position;
- detent means coupled to said ribbon support means for releasably retaining said ribbon support means at its first position;
- means for selectively releasing said detent means to release said ribbon support means for displacement from its first to its second position;
- and means coupling said transmitting member and said ribbon support means, when released, for displacing said ribbon support means from its second to its first position at which it is captured by said detent means during the displacement of said transmission member.
