Definitions

  • the field of the invention is that of printers, peripheral printers of central processing units such as printers integrated into printing devices, such as fax machines.
  • Thermal printing printers provided with a head of resistive heating elements, use as printing medium either thermal paper, in rolls, or plain paper in sheets.
  • the field of the invention is, more particularly, that of thermal printing printers using sheets of plain paper, that is to say thermal transfer printing printers.
  • the printing is carried out, under the action of the print head, by transfer of a hot-melt ink previously coated on a support film, the whole forming a printing ribbon.
  • the invention relates to these printing ink ribbons, therefore of a width at least equal to that of the sheets intended to be printed.
  • the present invention aims to overcome such manipulation.
  • a cassette for a thermal transfer printing ribbon arranged to be placed in a printer comprising a print head in front of which sheets of paper are intended to run, and comprising a housing for receiving a supply reel, a housing for receiving a take-up reel, means arranged to be driven in rotation and driving the take-up reel, a window being formed between the two housings and arranged to allow the cooperation of the head tape extending between the two slots.
  • the cassette is in one piece.
  • the window formed between the two housings is arranged to allow the cooperation of the ribbon and a support head.
  • means for guiding sheets of paper are associated with each of the two housings.
  • means for deflecting the path of the ribbon between the two housings are associated with the housing of the take-up reel in order, after printing, to facilitate the separation of the ribbon and the sheets of paper.
  • the housing of the take-up reel is associated with means for guiding sheets of paper and means for deflecting the path of the ribbon forming the baffle.
  • the cassette of the invention can be symmetrical with respect to a median plane extending through the window.
  • the means for driving the two coils in rotation are respectively arranged on two opposite sides of the cassette.
  • the cassette shown in Figures 1 and 2 has a housing 1 containing a ribbon 2 for thermal transfer printing.
  • the cassette is arranged to be placed in a printer, not entirely shown, which here belongs to a fax machine and includes a line print head 21 in front of which sheets of paper 30 to be printed are intended to be scrolled.
  • the cassette comprises a receiving housing 3 for a supply reel 4 of the tape 2, a receiving housing 5 for a receiving reel 6 and, in the receiving housing 5, a drive shaft 7 having coupling grooves in rotation with the take-up reel 6 and terminated by a pinion 8 making projection of the housing 1 containing the above elements.
  • a motor with gear 22 of the printer meshes with the pinion 8 to drive it in rotation and likewise drive the take-up reel 6.
  • a window 9 is formed between the two housings 3 and 5 and is here arranged to allow the cooperation of the print head 21 and ribbon 2 extending between the two housings 3 and 5.
  • a support roller 23 of the printer is opposite the printhead 21 and presses the paper 30 and the ribbon 2 against the printhead 21, while ensuring by friction the entrainment of the paper 30.
  • a shaft 17 is here provided to support the supply reel 4, as well as a brake 10 opposing the rotation of the shaft 17.
  • the ribbon 2 upstream of the print head 21 leaves the housing 3 while being guided, or deflected, by an extension 3R of the housing 3 extending towards the print head 21, while the ribbon 2 downstream of the print head 21 is guided, or deflected, by an extension 5R of the housing 5.
  • the extensions 3R and 5R are arranged so that the upstream ribbon 2 is approximately straight, while the downstream ribbon 2 is guided approximately an edge of the housing 5 opposite to the extension 5R, up to a rounded edge 5A making it follow a baffled path from which it departs towards an edge adjacent to the extension 5R by forming a very approximately right angle.
  • the ribbon 2 and the sheet 30 of printed paper remain bonded between the print head 21 and the edge 5A, where they separate at a relatively large angle.
  • the ribbon 2 is pulled by the action of the motor 22 and remains stretched by the effect of the brake 10, while the paper 30 is pushed by the roller 23. It is also possible to provide drive rollers to extract the paper 30 .
  • the housings 3 and 5 respectively have two other extensions 3P and 5P ensuring the guiding of the paper 30, in inlet, towards the head 21 and, at the outlet, from the head 21.
  • the extensions 3P and 5P are associated respectively with two guides 24 and 25 belonging to the same part of the printer and respectively arranged opposite the extensions 3P and 5P to constitute with them two guide channels, at the inlet and outlet of the paper 30.
  • the cassette is, here, in one piece and the window 9 allows the print head 21 and the support roller 23 to occupy a position interposed between the two housings 3 and 5, for which they cooperate.
  • the cassette shown in FIG. 3 has a general shape and elements similar to those shown in FIGS. 1 and 2, except that it has symmetry with respect to a median plane 140 extending through the window 109.
  • elements similar to those of FIGS. 1 and 2 bear identical references, preceded by the hundred 1 and, where appropriate, by the tens 1, and they are not described again.
  • the cassette of FIG. 3 carries two layers of ink allowing two passages in printing.
  • the cassette comprises a second pinion 118 integral with the shaft 117, for driving the reel 104 in rotation when, the cassette having been turned over in the printer, the reel 104 occupies the previous position, shown therein, of the take-up reel 106 and is driven by the motor 122.
  • the second pinion 118 is disposed on one side of the housing 101 opposite to that from which the pinion 108 projects, in order to occupy the place of the latter after turning the cassette over.
