  • the plate 18 is moreover provided with a series of apertures 21 (FIG. 1) each defined by two bent strips 22 housing a pin 23 on which a roller 24 (FIG. 3) is rotatable.
  • Each sideplate 20 is provided with an arm 25 to which a guide rod 26 for the paper strip I6 is fixed. Fulcrumed on the rod 26 are two levers 27 each connected to the respective arm 25 by a spring 28. The two levers 27 are connected by a bar 29 which normally keeps the paper strip ll6 under tension by the action of the springs 28.
  • two cylindrical members or knurled wheels 30 Disposed at the two sides of the type drum 13 are two cylindrical members or knurled wheels 30 having a diameter sub-. stantially equal slightly greater to that of the type drum l3 and adapted to be rotated independently of the type drum l3 and in synchronism with one another to control the line spacing of the paper strip 16.
  • the wheels 30 can moreover be rotated continuously when a key 52 carried by a shank 35 is depressed, in the manner described in the above-mentioned patent with reference to the key indicated therein by the reference 139.
  • the arrangement for guiding the paper strip 16 moreover comprises an arcuate plate formed of a convex paper-guiding cradle 32 disposed below and to the rear of the type drum l3 and the wheels 30.
  • the cradle 32 has two bent arms 33, each fulcrumed on a fixed pin 34, and two paper-pressing rollers 36 disposed at the two sides of the cradle 32.
  • a spring 37 anchored to a bent lug 38 of the cradle 32 normally holds the rollers 36 in contact with the wheels 30.
  • the left-hand arm 33 (FIG. 4) has a shoulder 42 which can cooperate with a lug 45 of a lever 44 pivoted on a fixed pin 46.
  • the paper strip 16 is further guided by a fixed guide 62 and I by a series of rollers 63 rotatable on a fixed shaft or rod 64.
  • the paper strip 16 is guided after printing in a tunnel means or passage generally indicated by the reference 65 and arranged below the path of the carriage 7.
  • the machine casing comprises a cover 68 integral with two arms 67 and made of plastic material. The arms 67 can rotate on two pins 66 fixed to the two sideplates 20.
  • the cover 68 (FIG.
  • I) has at the front end on top an opening 7] closed at the front by a metal section 72 by which it rests against an edge 73 of a front wall 74 (FIG. 3) of the casing of the machine.
  • a metal section 72 Fixed in the section 72 is a transparent window 79 provided with a serrated edge 81 to enable the strip 16 to be cut.
  • the cover 68 is moreover provided with two projections 82 to which a plate 83 is fixed.
  • a rod 85 on which two lugs 86 (FIG. 3) of a second plate 87 can turn.
  • the plate 87 is provided forwardly with a manipulative portion or front edge.
  • a spring 89 anchored to each lug 86 keeps the plate 87 bearing against a shoulder 91 of the cover 68 so as to form with the plate 83 a first part of the tunnel means 65.
  • the plates 83 and 87 form a leading part of the tunnel means 65.
  • the casing of the machine has to the rear of the plates 98 and 99 an inclined portion 103 terminating in a vertical portion 104 (FIG. 3).
  • This last-mentioned portion 104 is offset to the rear with respect to a backwall 106 in such manner as to form with the latter an exit slit 107 for the paper strip 16.
  • the paper strip 16 is then passed around the bar 29, the rod 26, between the cradle 32 and the type drum 13 and around the guide 62 and the rollers 63. If it is foreseen that the carriage 7 (FIG. 3) of the typewriter will not be transversely moved while operating the machine, the strip 16 is brought out between the edge 81 of the transparent window 79 and the front edges of the plates 83 and 87, The cover 68 is then placed in position again and the key 52 (FIG. 4) is depressed through a predetermined portion of its total travel. The key 52 acts by means of the lug 61 on the lug 58 of the latch 56, which new releases the lever 44. The spring 48, bringing the lever 44 back to its inoperative position,'allows the cradle 32 to bear against the wheels again by means of the rollers 36, as a result of which the machine can be used as a conventional calculating machine.
  • the key 52 (FIG. 4) is now depressed as in the preceding case, thus causing the cradle 32 to return to the position shown in FIG. 3.
  • the strip 16 advances within the tunnel means 65 until it encounters the inclined portion 103 of the casing. The strip 16 is then deflected downwards and emerges from the slit 107.
  • the key 52 is depressed for a greater distance than in the preceding case.
  • the key 52 in the manner described in the cited U.S. Pat. No. 3,33l,3l6 is arranged to cause repeated line spacing whereby the strip 16 advances rapidly within the tunnel means 65.
  • An accounting or like machine having an alphanumeric printing mechanism, a carriage for supporting a document, rail means for guiding said carriage along a rectilinear path for a transverse movement with respect to said alphanumeric printing mechanism to cause said alphanumeric printing mechanism to print in separate transverse positions of the document, a numeric printing mechanism located laterally adjacent to said alphanumeric printing mechanism, said numeric printing mechanism being operable for printing a paper strip fed from a tally roll, and a strip-feeding mechanism for feeding said paper strip past said numeric printing mechanism, wherein the improvement comprises:
