Abstract

Roller platen 6 is rotatably supported on shaft 7, journaled in frame member 13. Guide rollers 8 roll on guide member 9 as 6 is moved to the right during the print stroke. Member 9 slides on inclined surface 5 and is biased to the left by compression spring 12. Stationary shaft 23 serves as a pivot for 13 which is mounted on 23 by slots 29. Tension spring 27 connected between 23 and crossbrace 18 biases 8 into contact with 9. Torque spring 19 confined at one end by stop 20 and bearing at its other end upon 18, provides the motive force to draw 6 across the surface 25 to be printed on. When awaiting initiation of a print cycle, 9 is retained against leftward movement by detent 2, connected to solenoid 1. Catch 26 on 14 engages latch 15, preventing movement of 6.

13. Guide rollers 8 roll on guide member 9 as 6 is moved to the right during the print stroke. Member 9 slides on inclined surface 5 and is biased to the left by compression spring 12. Stationary shaft 23 serves as a pivot for 13 which is mounted on 23 by slots 29. Tension spring 27 connected between 23 and crossbrace 18 biases 8 into contact with 9. Torque spring 19 confined at one end by stop 20 and bearing at its other end upon 18, provides the motive force to draw 6 across the surface 25 to be printed on. When awaiting initiation of a print cycle, 9 is retained against leftward movement by detent 2, connected to solenoid 1. Catch 26 on 14 engages latch 15, preventing movement of 6.

To initiate a print cycle, 1 is energized, pulling 2 out of the path of 9. This frees the latter to move leftward, under the influence of 12, into the position shown at 30, placing 6 in the plane of surface 25. The upward movement of 9 also causes catch 26 to lift out of engagement with 15, freeing 13 to be moved rapidly to the right by 19, effecting a print stroke.

Direct-reading characters on type wheels 28 generate an inked impression on 25. The ink is supplied either directly by 6 or by an ink ribbon interposed between 6 and 25. At the end of the print stroke, 14 strikes stop member 10 mounted on crossbrace 11. The momentum of 13 carries 9 to the right, against the bias of 12, to it...
