Claim 1
Independent Claim
258 words
A multicolour inked ribbon cartridge for an impact serial printer of the type having a frame, a printing head slidably mounted on a carriage, said printing head being capable of sliding parallel to a platen for printing a character row on a printing support which leans against said platen, said multicolour inked ribbon cartridge comprising: a housing body for a multicolour ribbon formed by a plurality of longitudinal contiguous bands of different colours, said body being provided with two parallel arms so that a portion of said multicolour ribbon extends between the ends of said arms outside of said body, said portion of ribbon capable of being interposed between said printing head and said printing support along the entire printing line; means integral to said body for rotatably attaching said cartridge to said frame so that such body is able to rotate around an axis parallel to the direction of movement of said printing head; and guiding means mounted on and extending between the ends of said two arms, said guiding means for transmitting the angular displacements of said cartridge to a positioning and tensioning element of subsequent zones of said ribbon portion which are interposed between said printing head and said printing support during the printing process, said element, in its transverse 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 perpendicular to the direction of its transverse movement due to said cartridge rotation.
Claim 2
Dependent Claim

A multicolour inked ribbon cartridge for an impact serial printer of the type having a frame, a printing head slidably mounted on a carriage, said printing head being capable of sliding parallel to a platen for printing a character row on a printing support which leans against said platen, said multicolour inked ribbon cartridge comprising: a housing body for a multicolour ribbon formed by a plurality of longitudinal contiguous bands of different colours, said body being provided with two parallel arms so that a portion of said multicolour ribbon extends between the ends of said arms outside of said body, said portion of ribbon capable of being interposed between said printing head and said printing support along the entire printing line; means integral to said body for rotatably attaching said cartridge to said frame so that such body is able to rotate around an axis parallel to the direction of movement of said printing head; and guiding means mounted on and extending between the ends of said two arms, said guiding means for transmitting the angular displacements of said cartridge to a positioning and tensioning element of subsequent zones of said ribbon portion which are interposed between said printing head and said printing support during the printing process, said element, in its transverse 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 perpendicular to the direction of its transverse movement due to said cartridge rotation.
Claim 3
Dependent Claim
30 words
A mutlicolour ink ribbon cartridge as per claim 1, further characterized in that said guiding means is comprised of a string made tight between the ends of said two arms.
Claim 4
Dependent Claim
251 words
A positioning mechanism for a multicolour inked ribbon cartridge in an impact serial printer having a frame of the type wherein a printing head mounted on a carriage slides parallel to a platen for subsequently printing a character row on a printing support which leans against said platen, said cartridge comprising a housing body for a multicolour inked 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 ribbon extends freely outside said body, said ribbon portion being capable of being interposed between said printing head and said printing support along a whole printing line, said body being further provided with means for rotatably attaching said cartridge to said frame so that said cartridge is able to rotate around an axis parallel to the direction of movement of said printing head and having guiding means mounted on and extending between the ends of said two arms, said positioning mechanism comprising: actuation means supporting and positioning said body of said cartridge at selectable angular positions; a positioning and tensioning element of subsequent zones of said ribbon portion, which is interposed between said printing head and said printing support during the printing process; first means to restrain, perpendicular to the printing line, said positioning and tensioning element to said guiding means; and second means to restrain, parallel to the printing line, said positioning and tensioning element to the group comprised by said printing head and said carriage.
Claim 5
Dependent Claim
251 words
A positioning mechanism for a multicolour inked ribbon cartridge in an impact serial printer having a frame of the type wherein a printing head mounted on a carriage slides parallel to a platen for subsequently printing a character row on a printing support which leans against said platen, said cartridge comprising a housing body for a multicolour inked 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 ribbon extends freely outside said body, said ribbon portion being capable of being interposed between said printing head and said printing support along a whole printing line, said body being further provided with means for rotatably attaching said cartridge to said frame so that said cartridge is able to rotate around an axis parallel to the direction of movement of said printing head and having guiding means mounted on and extending between the ends of said two arms, said positioning mechanism comprising: actuation means supporting and positioning said body of said cartridge at selectable angular positions; a positioning and tensioning element of subsequent zones of said ribbon portion, which is interposed between said printing head and said printing support during the printing process; first means to restrain, perpendicular to the printing line, said positioning and tensioning element to said guiding means; and second means to restrain, parallel to the printing line, said positioning and tensioning element to the group comprised by said printing head and said carriage.
Claim 6
Dependent Claim
52 words
A positioning mechanism for a multicolour inked ribbon cartridge as per claim 3, further characterized in that said first means comprises a pair of opposed teeth forming a hook with a flat eye, which is an integral part of said positioning and tensioning element, sliding along the axis of said guiding means.
Claim 7
Dependent Claim
50 words
A positioning mechanism for a multicolour inked ribbon cartridge as per claim 3 further characterized in that said second means comprises: a shaft at least, integral to said carriage; and a hollow pin at least, integral to said positioning and tensioning element, said shaft being inserted in said hollow pin.
