Abstract
Abstract Multicolour inked ribbon cartridge for an impact serial printer comprising a ribbon housing body and two arms protruding from such body to allow the interposition of a ribbon portion between printing head and printing support for the whole length of the platen when the cartridge is inserted by means of two lateral cylindrical shaped projections provided on the body into two suitable housings of the serial printer frame, allowing rotation of the body around a common axis of said cylindrical projections, parallel to the platen. The cartridge rotation around such axis and therefore the positioning of a suitable multicolour band between printing head and printing support is assured by a cam actuated by a motor and interacting with the body of such cartridge. The cartridge is further provided with a string tight between the ends of its arms upon the multicolour ribbon portion interposing between head and printing support. Such string is devoted to hitch a ribbon positioning and guiding element, which therefore follows the cartridge rotation, and at the same time, being suitably coupled to the carriage of the serial printer, follows the printing head in its transversal shift in order to assure a correct positioning and tensioning of the subsequent zones of the multicolour ribbon contacted by the printing head.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
162 words
MuLticoLour inked ribbon cartridge for impact serial printer of the kind where a printing head mounted on a carriage slides parallely to a platen for subsequently printing a character row on a printing support Leaned against said platen, comprising: - an housing body for a multicolour ribbon formed by a plurality of LongitudinaL contiguous bands of different colour, said body being provided with two parallel arms, a portion of said multicolour ribbon extending between the ends of said arms outside said body, said portion of ribbon being intended to interpose between said printing head and said printing support along the whole prin ting Line, characterised by that it comprises: - two cylindrical shaped projections protruding externally from said body, said projections being insertable in suitable housing of the frame of said printer in order that such body is able to rotate around the axis of said two projections, said axis being parallel to the direction of the movement of said printing head.
Claim 2
Dependent Claim
162 words
MuLticoLour inked ribbon cartridge for impact serial printer of the kind where a printing head mounted on a carriage slides parallely to a platen for subsequently printing a character row on a printing support Leaned against said platen, comprising: - an housing body for a multicolour ribbon formed by a plurality of LongitudinaL contiguous bands of different colour, said body being provided with two parallel arms, a portion of said multicolour ribbon extending between the ends of said arms outside said body, said portion of ribbon being intended to interpose between said printing head and said printing support along the whole prin ting Line, characterised by that it comprises: - two cylindrical shaped projections protruding externally from said body, said projections being insertable in suitable housing of the frame of said printer in order that such body is able to rotate around the axis of said two projections, said axis being parallel to the direction of the movement of said printing head.
Claim 3
Dependent Claim
28 words
MuLticoLour inked ribbon cartridge as per claim 1 further characteri sed by that the axis of said two projections does not get through the barycenter of said cartridge.
Claim 4
Dependent Claim
124 words
MuLticoLour inked ribbon cartridge as per claim 1 further characte rised by that it comprises: - guiding means between the ends of said two arms, said guiding means being intended to transmit the angular displacements of said cartridge to a positioning and tensioning element of the subsequent zones of said ribbon portion between the ends of said two arms which are interposed between said printing head and said printing support during the printing process, said element, in its transversal movement along the printing Line together with said printing head, being able to slide along the axis of said guiding means, said element being coupled to said guiding means and also movable perpendicularly to the direction of its transversal movement due to said cartridge rotation.
Claim 5
Dependent Claim
31 words
Multicolour inked ribbon cartridge as per claim 3, further charac terised by that said guiding means are constituted by a string up perty tight between the end of said two arms.
Claim 6
Dependent Claim
195 words
Positioning mechanism of a multicoLour inked ribbon cartridge in an impact serial printer having a frame of the type where a printing head mounted on a carriage slides parallely to a platen for subsequently printing a character row on a printing support Leaned against said platen, said cartridge comprising a housing body for a multicolour ribbon formed by a plurality of LongitudinaL contiguous bands of different colour, said body being provided with two arms between whose ends a portion of said multicolour ribbon extends freely, out side said body, said portion of ribbon being intended to interpose between said printing head and said printing support along the whole printing line, said body being further provided with two cylindrical shaped projections for engagement into two suitable housings characterised by that it comprises: - two housings in said frame, each for receiving one of said projec tions and rotatably mounting said cartridge in said frame with a rotation axis parallel to the movement direction of said print ing head, and - a cam actuated by electro-mechanical means, supporting and positioning said body of said cartridge at selectable angular positions defined by said cam and said electromechanical means.
Claim 7
Dependent Claim
195 words
Positioning mechanism of a multicoLour inked ribbon cartridge in an impact serial printer having a frame of the type where a printing head mounted on a carriage slides parallely to a platen for subsequently printing a character row on a printing support Leaned against said platen, said cartridge comprising a housing body for a multicolour ribbon formed by a plurality of LongitudinaL contiguous bands of different colour, said body being provided with two arms between whose ends a portion of said multicolour ribbon extends freely, out side said body, said portion of ribbon being intended to interpose between said printing head and said printing support along the whole printing line, said body being further provided with two cylindrical shaped projections for engagement into two suitable housings characterised by that it comprises: - two housings in said frame, each for receiving one of said projec tions and rotatably mounting said cartridge in said frame with a rotation axis parallel to the movement direction of said print ing head, and - a cam actuated by electro-mechanical means, supporting and positioning said body of said cartridge at selectable angular positions defined by said cam and said electromechanical means.
Claim 8
Dependent Claim
118 words
Positioning mechanism of a mutLicoLour inked ribbon cartridge as per claim 5 where said cartridge is further provided with a guiding mean extending between the ends of said two arms, further characterised by that it comprises: - a positioning and tensioning element of the subsequent zones of said ribbon portion extending between the ends of said two arms which are interposed between said printing head and said printing support during the printing process, - first means to restrain, perpendicularly to the printing Line said positioning and tensioning element to said guiding means, - second means to restrain, parallely to the printing Line, said positioning and tensioning element to the group constituted by said printing head and said carriage.
Claim 9
Dependent Claim
43 words
Positioning mechanism for a multicolour inked ribbon cartridge as per claim 6 further characterized by that said first means comprises an hook with flat eye, which is integral part of said positioning and tensioning mechanism, sliding along the axis of said guiding means.
