Abstract

Abstract In an accounting machine having an alphanumeric printing mechanism and a numeric printing mechanism the paper carriage for the alphanumeric mechanism is guided by a rail located to the rear of the numeric mechanism. This latter is adapted to print on a tally roll adapted to be housed in a substantially semicylindrical plate located under the guiding rail and provided with a set of parallel apertures for a set of rotatable rollers supporting the tally roll. The paper of the roll is so guided as to pass after printing along a path beneath said guide rail, a slit on the rear wall of said cover being provided for the exit of the printed paper of said roll.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 281 words
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: a. at least a first cylindrical member included in said strip feeding mechanism for guiding the paper strip, said cylindrical member being rotatable for advancing said paper strip and lying substantially forwards and downwards with respect to said rectilinear path, b. a substantially semicylindrical plate located under said rectilinear path, said plate forming a concave seat for said tally roll, c. a machine casing including a rear wall and a cover located above said semicylindrical plate and rockable backwards, d. tunnel means mounted on said machine casing for guiding said paper strip from said numeric printing mechanism along another path located between said concave seat and said rectilinear path, thus enabling said carriage to be moved transversely to a superimposed relationship with respect to said tunnel means, e. a first pair of guiding plates forming a portion of said tunnel means and secured to said cover for allowing the insertion of a fresh tally roll into said concave seat by so rocking said cover, and f. a slit on the rear wall of said machine casing for the exit of said paper strip.
Claim 2
Dependent Claim 281 words
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: a. at least a first cylindrical member included in said strip feeding mechanism for guiding the paper strip, said cylindrical member being rotatable for advancing said paper strip and lying substantially forwards and downwards with respect to said rectilinear path, b. a substantially semicylindrical plate located under said rectilinear path, said plate forming a concave seat for said tally roll, c. a machine casing including a rear wall and a cover located above said semicylindrical plate and rockable backwards, d. tunnel means mounted on said machine casing for guiding said paper strip from said numeric printing mechanism along another path located between said concave seat and said rectilinear path, thus enabling said carriage to be moved transversely to a superimposed relationship with respect to said tunnel means, e. a first pair of guiding plates forming a portion of said tunnel means and secured to said cover for allowing the insertion of a fresh tally roll into said concave seat by so rocking said cover, and f. a slit on the rear wall of said machine casing for the exit of said paper strip.
Claim 3
Dependent Claim 120 words
An accounting or like machine according to claim 1 further comprising: g. a set of parallel apertures provided at different angular positions on said semicylindrical plate, said apertures being arranged in said semicylindrical plate in at least one circumferential row, h. a set of parallel pine mounted on said semicylindrical plate in correspondence with said apertures, and i. a set of rollers each one mounted on one of said pins and freely rotAtable with respect to said semicylindrical plate, said rollers entering the corresponding apertures of said semicylindrical plate and having such a diameter as to engage the external surface of said tally roll in said concave seat at a small distance from the internal surface of said semicylindrical plate.
Claim 4
Dependent Claim 179 words
An accounting or like machine according to claim 1, having another cylindrical member included in said strip-feeding mechanism and axially distanced from said first cylindrical member, and a rotatable type drum comprised in said numeric printing mechanism and located coaxially with said cylindrical members, said cylindrical members being formed of a pair of knurled wheels having a diameter slightly greater than the diameter of said type drum, said type drum being continuously rotatable independently from said knurled wheels, wherein the improvement comprises: g. an arcuate plate embracing said knurled wheels and said type drum and pivotally mounted and yieldably urged towards said knurled wheels for guiding said paper strip from said tally roll towards said type drum, h. a control member operable for rockably moving said arcuate plate away from said knurled wheels to facilitate the insertion of said paper strip around said knurled wheels, i. a first key depressible for operating said control member, j. latching means for latching said control member in the operated position, and k. a second key depressible for rendering ineffective said latching means.
Claim 5
Dependent Claim 108 words
An accounting or like machine according to claim 1, further comprising: l. a second pair of guiding plates comprised in said tunnel means and carried by said cover, said second pair of guiding plates being so located as to form a leading part of said tunnel means, m. means for tiltably mounting one of said second pair of guiding plates with respect to the other plate of said second pair of guiding plates, and n. a manipulative portion integral with said tiltable plate and operable to tilt said tiltable plate so as to facilitate the insertion of the leading edge of said paper strip into said tunnel means.
