Definitions

  • the invention relates to a drive device for a Ribbon cassette that can be used in a printer's frame according to the preamble of claim 1.
  • a printer of the type mentioned is from DE 43 15 510 A1 known.
  • the printer described in it comes with a single drive motor for all movements:
  • the Motor feeds the printhead along the Print line and with the print head drive is a control disc coupled, depending on their angular position the feed of a record carrier or a cutting device drives.
  • Ribbon transport no information can be found in the publication.
  • a drive device is already known from EP-A-0 267 480 for a stationary use in the printer frame of a printer Ribbon cassette known, the drive device a coupling end for the ribbon feed mechanism the ribbon cassette includes.
  • the drive device a coupling end for the ribbon feed mechanism the ribbon cassette includes.
  • a gear wheel arranged on a rocker arm for an ink ribbon drive device which depends on the direction of movement a print head carriage with a drive wheel or a reversing gear is both in US-A-4,596,480 as well as in PATENT ABSTRACTS OF JAPAN, vol.11, no.6 (M-551) [2453] & JP-A-61 182 976 described. In both cases, the drive device attached to the print head carriage.
  • a drive device for a ribbon with an only in one direction revolving motor is from US-A-3 854 670 known.
  • One on a swing arm, with one Reversing gear cooperating gear reverses the transport direction of the ribbon when the tension in the Ribbon exceeds a specified value.
  • the invention has for its object a drive device for a stationary in the printer frame of a printer arranged ribbon cassette to indicate the kinetic energy derived from a control disc, the rotation of which is coupled with the movement of a printhead.
  • the task is characterized by the characterizing features of the claim 1 solved.
  • crank pin on the side of the control disc to attach the connecting rod to the rack attacks.
  • the crank pin With the radial distance of the crank pin from the center of the control disc is easier Way the stroke of the rack and thus the feed width of the ribbon. It is also the invention Solution so applicable to control disks, the one Transport of the print head over the entire length of the print line make several turns without the length of the rack to change.
  • Figure 1 shows a printer 10, which is used as a structural unit executed in a cash box (not shown) is.
  • Two side walls 12 hold those arranged in parallel cylindrical guide rails 14, between which a printhead holder 16 is performed.
  • the print head holder 16 can record a printhead 16 ', for example after the Mosaic printing process prints color dots line by line.
  • Of the Printhead holder 16 is reversible by one of a DC motor 28 driven, not illustrated timing belt on the guide rails 14 back and forth moved. The timing belt is tight with the Printhead holder 16 connected so that by the rotation of the reversible motor different printing positions lengthways the guide rails 14 with high repeatability can be controlled.
  • the printer 10 includes a paper supply roll 18 for Receipts and a paper supply roll 20 for journal printing.
  • the paper of the paper supply rolls 18, 20 is guided along the guides, not shown, past the print head and can be output via output chutes 22 become.
  • the movement of the toothed belt is via a gear transmission transferred to a control disc 24 with a ring gear.
  • This control disc 24 has a switching cam 26, which a ratchet mechanism 30 a line switch device operated.
  • printer 10 corresponds to that in DE 43 15 510 A1 printer described. There is also the way he works explained in more detail.
  • a crank pin 32 On the outwardly facing surface of the control disk 24 a crank pin 32 is attached. On this is one End of a connecting rod 34 rotatably mounted, the other End is pivotally connected to a rack 36. over the toothing is attached to the side of the rack 36 in engagement with an adjacent ribbon transmission 40, which is described in more detail below becomes.
  • the output side of the ribbon transmission 40 is through a drive shaft 42 is formed, which to a coupling end 44 is formed with a cross-shaped cross-sectional profile. This is designed to be complementary in shape Coupling recess in the transport roller of a known and therefore not shown ribbon cassette intervene positively.
  • the ribbon transmission 40 is described below with reference to FIG. 2 described in more detail, with all of them below mentioned wheels are spur gears.
  • the Rack 36 engages with a switching wheel 46, that at one end of a rocker 48 on a shaft 50 is rotatably mounted.
  • the other end of the swing arm is pivotally mounted on a pin 52 on the printer frame.
  • To the right of the rocker 48 is a drive wheel 54, left a turning wheel 56.
  • Both wheels form a pair of gears, which is arranged symmetrically to the pin 52 so that their centers with the pin 52 isosceles Form a triangle, the base of which is approximately midway between the Shaft 50 and pin 52 and parallel to rack 36 lies.
  • With the turning wheel 56 there is a driving wheel 58 in Engagement the shaft 42 (Fig. 1), as already described, runs out in a cruciform coupling end 44.
  • Fig. 3 is a second embodiment of an ink ribbon transmission 40 'shown. This differs of the ribbon transmission 40 (Fig. 2) only in that the Coupling end 44 'formed on the shaft of the drive wheel 54' is. As a result, the driving wheel 58 can be omitted.
  • the principle of operation is 40 for both ribbon drives, 40 'equal. It is described below with reference to FIG. 3.
  • the rack 36 is due to a Rotation of the control disk 24 in Fig. 1 in the direction of Arrow x moves.
  • the switching wheel 46 becomes counterclockwise turned. This rotary movement is transmitted on the drive wheel 54 ', whereby the coupling end 44' in Is turned clockwise and a ribbon feed in causes a ribbon cassette, not shown.
  • the transmission is carried out described movement of the rack 36 over the switching wheel 46 on the drive wheel 54 and from there on the turning wheel 56 and the driving wheel 58 on the coupling end 44, which is also clockwise in this embodiment turns.
  • FIG. 4 is a third embodiment of a ribbon transmission 40 '' shown.
  • a 24 '' control disc which otherwise corresponds to the control disk 24 in FIG. 1, is a gearwheel 60 coaxial with it and externally toothed non-rotatably connected. With this one combs on one surface of a square toothed rack 36 '' first toothing 62. One on a side surface the rack 36 '' attached second toothing 64 is with the switching wheel 46 in engagement, its arrangement and Function already in connection with Figures 2 and 3 is described.
  • By turning the control disc back and forth 24 '' becomes the rack 36 '' as there for the rack 36 described moving back and forth.
  • an external toothing can also be used directly on the - compared to this larger - control disc 24 '' can be provided, with which the first toothing 62 the rack 36 '' is to be engaged. This is especially true for printers with only a few characters per print line interesting because of the through the larger diameter of the control disc 24 '' larger number of teeth, the rack 36 '' and thus the ribbon experiences a greater feed.
  • a smaller gear 60 has a smaller number of teeth, so that the rack 36 '' experiences a lower feed rate. Such a gear is advantageous for printers 10 with larger print widths.
