Definitions

  • the invention relates to a printer, comprising a print head; a paper path for a document to be printed; and an ink ribbon cartridge with a drive motor and transmission means belonging thereto.
  • the invention additionally relates to an ink ribbon cartridge for a printer, which cartridge comprises a frame, an ink ribbon and a drive wheel for driving the ink ribbon, which drive wheel is positioned in such a way that its axle is perpendicular to the level formed by the frame.
  • the object of the present invention is to eliminate the problems described above by means of a novel printer and ink ribbon cartridge. This object is achieved by means of a printer of the invention, which is characterised in the features presented in claim 1; and by means of an ink ribbon cartridge of the invention, which is characterised in the properties presented in claim 7.
  • the invention is based on an idea to use a pair of coupled drive wheels in connection with an ink ribbon cartridge, which wheels form a 90° angle with each other, whereby the drive from the printer to the ink ribbon cartridge can be arranged by means of a straight drive shaft parallel with the cartridge surface. Only one movement in one direction is then needed for changing the cartridge and for coupling the drive shaft.
  • the pair of drive wheels serves as a reduction gear, and so the transmission between the drive motor and the drive shaft does not need to transmit any big torque. Due to this the drive wheels and the drive shaft can preferably be manufactured of plastic without losing their reliability.
  • An advantage of the invention is also that the manufacture, assembly and mounting of the cartridge, i.e. the tolerances, do not influence the drive mechanism in a disadvantageous manner.
  • Figures 1 and 4 show a printer according to the invention, comprising a print head 1, a paper path 2 for a document to be printed and an ink ribbon cartridge 3 with a drive mechanism 4, 5, 6, a drive motor 7 and transmission means 8 to 14 belonging thereto.
  • Figure 4 relates to an area X of Figure 1 and shows the arrangement of the cartridge 3 in the printer in the direction of arrow A, obliquely from below.
  • Figure 1 shows the printer simplified and not all the details thereof are shown. Additionally, Figure 1 shows the ink ribbon cartridge 3 separately from the printer.
  • the drive mechanism of the ink ribbon cartridge 3 comprises a pair of drive wheels, which wheels 4 and 5 form a 90° angle with each other.
  • the axle of the first wheel 4 is perpendicular to the level or major surface formed by the cartridge 3 and the axle of the second wheel 5 is parallel with the level formed by the cartridge 3.
  • the drive mechanism comprises further a straight drive shaft 6 positioned between the second wheel 5 and the transmission means 8 to 14.
  • Both drive wheels 4 and 5 are mounted to fixed positions in a frame 3a of the cartridge 3 (see especially Figures 2 and 3).
  • the drive wheels 4 and 5 can be for instance gear wheels, friction wheels or pin wheels.
  • the drive shaft 6 can be a separate part or it can form an integral whole with the second drive pulley 5.
  • Figure 4 may concern both cases, because structures like this do not necessarily differ from each other, as far as appearance is concerned, when the cartridge 3 is fastened to the printer.
  • the ink ribbon cartridge 3 of the invention is substantially similar to the prior art ink ribbon cartridges, except for the drive mechanism described above, and includes an ink ribbon 3b, which is folded within the frame 3a in a conventional manner and with which the first drive wheel 4 is in driving contact.
  • the present invention it is extremely simple to mount the ink ribbon cartridge 3 in the printer.
  • the cartridge 3 is pushed into guide track 15 of the printer by means of one horizontal movement (arrow B in Figure 1) and the drive shaft 6 is simultaneously coupled between the transmission means 8 to 14 and the second drive wheel 5 of the cartridge 3. Because the drive shaft 6 usually is ready-fastened to the transmission means or fastened to the cartridge 3, no problems are caused by coupling the drive shaft either.
