Wire Printer

The wire printer is equipped with a cartridge for feeding a duplicated strip of medium upon which printing is to occur and for delivering the printed original strip while the duplicated one is stored within the cartridge.

The wire printer comprises a print station composed of wires arranged in a column array and disposed in front of print platen 1. Strip 2 to be printed and its duplicate 3 are contained within cartridge 4 comprising supply reel 5 and take-up reel 6. Strips 2 and 3 are made of self-printing paper. Strips 2 and 3 are simultaneously drawn from reel 5 by capstan 7 cooperating with pressure roller 8. Capstan 7 is rotated by driving pinion 9, the internally knurled hub 10 of which engages a corresponding driving shaft mounted on the printer when cartridge 4 is positioned on the printer. Reel 5 is provided with gear 11 meshing an associated gear secured to reel 6. Thus, when reel 5 rotates under the traction exerted by capstan 7 upon strips 2 and 3, rotation of take-up reel 6 occurs. Adequate slip spring clutches are provided on the axles of the reels for compensating the diameter variations of the two spools.

Two sets 12 and 13 of guiding rollers are provided for guiding the strips past the print platen and then for separating the printed original 2 from its duplicate 3. The latter is taken up by reel 6 while the printed original is delivered.

Pinion 9 is rotated step-by-step so that the strips are fed step-wise past the printing station....
