Definitions

  • the invention relates to an inkjet printer with a Cover and cleaning device for the ink nozzles an inkjet print head according to the preamble of Claim 1.
  • An inkjet printer with a cover and cleaning facility for the ink nozzles of an ink print head is known from DE-C-36 11 666.
  • that of the Record carrier maximum ingestible and from the ink print head maximum printable area is a parking area with a cover device and a cleaning device arranged for the ink nozzles of the ink print head.
  • the parking area gives the printer a width that not accepted in some applications can. This is especially true for POS printers of the type for example in the international patent application WO-A-9 840 219.
  • Such cash register printers will be often built into a cutout in a checkout counter, so that there is a quasi standard for their base area has formed with a width that is little larger than the width of the largest to be printed on Document.
  • This has A4 format, so one Width of 210 mm. This is the case with printers in this class The ink printing principle has therefore not yet been used.
  • the object of the invention is therefore for an inkjet printer with one in the print area of the ink print head arranged covering and cleaning device for the ink nozzles of the ink print head provide support to propose for a record carrier that at Place the cover and cleaning device in the Pressure range can be brought.
  • the cover device and the cleaning device are arranged in the print area of the ink print head.
  • the cover device, the cleaning device and the support section for the recording medium on the circumference of a circular or circular segment-shaped disc are arranged around a through the center of the circle extending axis is rotatable, no additional Space for a parking area outside the printing area or in front of and behind the ink printhead.
  • the Disc can be anywhere within the pressure range Print line to be arranged.
  • the axis can be parallel to the platen as well also perpendicular to this and parallel to the plane of the record carrier be aligned.
  • the disc is preferably driven by a motor, in particular rotated a stepper motor. In the latter case it can the angular position of the disc simply by counting the Motor step impulses are recorded.
  • the drive of the Disk preferably takes place via a toothing on at least a part of its scope, which with a through the Motor driven gear meshes.
  • the Slidable along the platen thereby can be used with a POS printer with a receipt printing station, as he from the German patent application 197 09 941.6 is known, the disc in the part of Print area that is not shifted from the receipt paper strip is occupied. If a receipt is placed side by side and used a journal printing station, the disc can in the gap between the receipt and journal paper strips to be brought.
  • the covering device In order for the cover device to be lifted off normal to the surface the nozzle plate of the ink printhead, is the covering device with the disc over a radial adjustable slider connected, and on the slider is a control pin attached in one in the inkjet printer arranged, the axis helical surrounding control curve is guided.
  • the control curve is on one held on the axis, opposite the disc stationary control plate, i.e. not with the disc rotating educated.
  • Fig. 1 is a first embodiment of an ink jet printer 10 in a schematic perspective Front view shown in which all not relevant to the invention Printer parts are omitted.
  • From the side of the side wall that faces the inside of the printer 12 is a bar-shaped platen 14 normal to the surface from. This is due to a gap 16 in the middle area of the inkjet printer divided into two parts 14 ', 14 ".
  • the platen 14 is on a paper guide surface 38 (FIG. 2).
  • an ink print head 18 Along the platen 14 and parallel to this is an ink print head 18 below Formation of a print line in the direction of a double arrow A slidably mounted.
  • the gap 16 there is a cylindrical disk 20 ⁇ m an axis 22 which coincides with the cylinder axis, rotatably mounted.
  • the axis 22 runs parallel to the Platen 14 on its side facing away from the ink print head 18 Page.
  • a covering device 24, a cleaning device 26 and a support section 28 are on the circumference of the disc 20, respectively offset with respect to one another.
  • the covering device 24 has the shape of a open towards the nozzle plate of the ink print head 18 Cap and consists of an elastically deformable ink-resistant plastic or rubber.
  • the cleaning facility 26 has the shape of a radially from the peripheral surface the disk 20 protruding axially aligned Plate. It is also made of an elastically deformable ink-resistant plastic or rubber formed.
  • the support section 28 is a section enlarged Disc diameter. It extends over the entire Width of the disc 20. Is the latter rotated so that the Support section 28 faces the ink print head 18, the surface of the support section 28 has the
  • the disc 20 is in the direction of a within the gap 16 Double arrow B between positions 20 '(with solid lines) and 20 "(dashed drawn) movable.
  • position 20 " is the Disc 20 shown in an angular position in which the cover device 24 faces the ink print head 18 is.
  • the cap-like shape is in this angular position the cover device 24 can be seen.
  • the setting of the Disc 20 when printing a gap 16 overlapping Document 34 is described below.
  • Fig. 2 shows a schematic side view of the in Fig. 1 illustrated inkjet printer 10.
  • the disc 20 is mounted on a coaxial shaft 36. Further is they in their peripheral area facing away from the paper guide surface 38 provided with a toothing 40 which with a gear 44 which can be driven by a stepper motor 42 combs.
  • the cover 24 is radial at one end arranged to the disc 20 adjustable slide 46, which is rotatable together with the disc 20.
  • To the Slider 46 is aligned parallel to the shaft 36
  • Control pin 48 attached in a helical shape the cam 22 surrounding the axis 22 is guided. This, in turn, is held on a shaft 22 fixed to the disc 20, so not with this co-rotating control plate 52 formed.
  • the slider 46 is in the region of the shaft 36 with an elongated hole 54 provided with which it is longitudinally displaceable on the shaft 36 is stored.
  • the control pin 48 runs along the cam 50.
  • the slide 46 is radial in the direction of the axis 22 moved so that the cover 24 of the Nozzle plate of the ink print head 18 lifted off and after is swung away in front of this.
  • the disk 20 enters the cleaning device 26 the area of the ink print head 18. It becomes elastic deflected so that their leading, parallel to the axis 22 aligned edge 56 the nozzle plate of the Ink printhead 18 sweeps over and on this removes any adhering contaminants.
  • By multiple Turning the disk 20 back and forth can have the cleaning effect still be increased.
  • the disk 20 is used for printing rotated further until the support section 28 reaches the pressure area 18 faces. Now the latter can be in the print line direction can be moved across the entire printing area.
  • the disc 20 starting from the in Fig. 2nd shown position, in which the printing area 18 covered is controlled as follows: The leading edge of a the inkjet printer 10 in the direction of arrow C fed document 34 is from one in front of the platen 14 arranged first light barrier 58 recognized, whereupon a document transport device, not shown is stopped. Then the disc 20 is like described above until the support portion 28 the Ink printhead 18 faces. The gap 16 is thereby largely closed, so that the document 34 also in this area is supported. Reaching this Position is based on the number of the stepper motor 42nd fed impulses determined and thus the document transport device Approved.
  • the document 34 After printing on the Document 34 is either in or against the direction arrow C transported from the ink jet printer 10.
  • the document 34 has the inkjet printer 10 with Leave safety if neither the first photoelectric sensor 58 another one arranged above the platen 14 second light barrier 60 the presence of a document reports.
  • the disc 20 is then turned clockwise into the Turned back position in which the cover 24th the nozzle plate of the ink printhead 18 covers what again based on the number of the stepper motor 42 fed Impulses is determined.
  • Fig. 3 shows a second embodiment of an ink jet printer 100 in a schematic top view. This differs from that in FIGS. 1 and 2 illustrated inkjet printer 10 in that the Axis 122 and thus the shaft 136 of the disk 120 perpendicular to the platen 114 ', 114 "and parallel to Level of a recording medium 134 is aligned.
  • the disk 120 is shown in its ready-to-print position, otherwise the arrangement is the same as that shown in FIG. 2 identical. The same positions are therefore with marked with the same reference numerals.
