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. Both print paper and inked ribbon are selectively advanced by a transmitting lever. The transmitting lever is mounted for reciprocal displacement and is operatively coupled to a continuously rotating member for selective displacement in response to the rotation of the rotating member. The print paper is guided by an upper and a lower paper guide, each of which are provided with projections on the inner surface thereof extending in the direction of travel of the print paper and projecting toward the other paper guide. The projections on the two guides are out of overlapping relation with each other. The gap between the outer surfaces of the projections of the respective paper guides is substantially equal to the thickness of the print paper.
In a compact flying printer, the improvement in a guide for print paper which comprises an upper paper guide and a lower paper guide in spaced overlapping relation to said upper paper guide for the passage of said print paper therebetween, each of said upper and lower paper guides being formed with at least one rib extending along the surface thereof facing the other of said upper and lower paper guides substantially in the direction of displacement of said print paper, the ribs on each of the upper and lower paper guides projecting toward the other of said upper and lower paper guides and terminating at outer ends facing the other of said upper and lower paper guides, the ribs on the respective upper and lower paper guides being out of overlapping relation and dimensioned to define a gap between the outer ends of the ribs of said upper paper guide and the outer ends of the ribs of said lower paper guide measured in a direction substantially normal to said upper and lower paper guides, said gap being substantially equal to the thickness of said print paper for receipt of said print paper, whereby the respective ribs of each of said upper and lower paper guides do not project beyond the outer ends of the ribs on the other of said upper and lower paper guides.

In a compact flying printer, the improvement in a guide for print paper which comprises an upper paper guide and a lower paper guide in spaced overlapping relation to said upper paper guide for the passage of said print paper therebetween, each of said upper and lower paper guides being formed with at least one rib extending along the surface thereof facing the other of said upper and lower paper guides substantially in the direction of displacement of said print paper, the ribs on each of the upper and lower paper guides projecting toward the other of said upper and lower paper guides and terminating at outer ends facing the other of said upper and lower paper guides, the ribs on the respective upper and lower paper guides being out of overlapping relation and dimensioned to define a gap between the outer ends of the ribs of said upper paper guide and the outer ends of the ribs of said lower paper guide measured in a direction substantially normal to said upper and lower paper guides, said gap being substantially equal to the thickness of said print paper for receipt of said print paper, whereby the respective ribs of each of said upper and lower paper guides do not project beyond the outer ends of the ribs on the other of said upper and lower paper guides.
