Definitions

  • the invention relates to a printing apparatus according to the preamble of claim 1.
  • Printing apparatuses are known for example as printers, fax machines and/or copying machines.
  • Known printing apparatuses often comprise the paper cassette for providing a stack of paper.
  • the JP 06 247 568 A shows a paper cassette with stoppers to limit the capacity of the paper cassette.
  • the JP 11 165 884 A shows a roteable filling-level limiting apparatus of a paper cassette.
  • the JP 2004 189 388 A discloses a cover sensor able to detect a maximum capacity exceeding.
  • the US 2007/040 323 A describes a stopper mechanism preventing a sheet to enter the paper cassette in the first direction while a sheet within the paper cassette is able to be moved in the second direction to be fed to the printer.
  • the disadvantageous aspect in conventional printing apparatuses with conventional paper cassettes is that when the paper cassette is filled completely, i.e. it is filled to 100% capacity or even more, which means it is provided with more sheets of paper than required, the removal of the sheets of paper from the stack of paper in the printing apparatus occurs repeatedly in a faulty way, which means oftentimes not with the required high reliability.
  • the occurring faults are that two sheets are drawn in simultaneously, that no sheet is drawn in or that a sheet is damaged when drawn in, e.g. it is torn.
  • the disadvantageous aspect is that the printing process is incomplete and/or erroneous or that the printing process is interrupted. It is further disadvantageous in this respect that in the erroneous drawing of the sheet of paper there will be a paper jam in the printing apparatus and printing can only be resumed after operator intervention, thus leading to a waste of time and/or additional costs. Two simultaneously withdrawn sheets of paper can further cause erroneous printing.
  • the printed document may comprise disturbing empty sheets which may have to be sorted out.
  • the invention further relates to a method according to the preamble of claim 10.
  • Figs. 1 and 2 show a preferred first embodiment of a paper cassette 1 of a printing apparatus with at least one paper cassette 1 for receiving a stack of sheets 2, especially a stack of paper, with the paper cassette 1 being provided for arrangement in a readiness position and in a loading position, with stack of sheets 2 arranged for removal of sheets for a printing process in the readiness position of paper cassette 1 and the paper cassette 1 is arranged for loading with sheets, especially paper, in the loading position, with the paper cassette 1 comprising a filling-level limiting apparatus 3 for predetermining the maximum filling level 4 of the receivable stack of sheets 2, and with filling-level limiting apparatus 3 being provided in the loading position of the paper cassette 1 for contact with an upper surface 21 of the stack of sheets 2.
  • the filling-level limiting apparatus 3 is arranged at a distance from an upper surface 21 of the stack of sheets 2.
  • either the filling-level limiting apparatus 3 and/or the stack of paper are displaced relative to one another during the displacement of the paper cassette from its loading position to its readiness position.
  • the uppermost sheet of the stack of sheets 2 which thus forms the upper surface 21 of the stack of sheets 2 rests in a substantially loose manner on the one but top sheet of the stack of sheets 2 and substantially low holding forces act thereby. It is advantageous that the uppermost sheet can be withdrawn with a low amount of effort and with high reliability from the stack of paper and can be drawn for printing into the printing apparatus. It is also advantageous in this respect that the reliability is high that only one sheet is drawn in during the withdrawal of the uppermost sheet into the printing apparatus. It is further advantageous that during the withdrawal of the uppermost sheet into the printing apparatus the sheet of paper is twisted merely to a very low extent, thus preventing with a high amount of reliability the tearing, deformation and/or twisting of the sheet to be drawn in.
  • a paper jam during the withdrawal of the uppermost sheet can advantageously be prevented and similarly the positioning of the withdrawn sheet in the printing apparatus can be improved, so that the printed image can be positioned with more precision on the sheet of paper and/or further means for positioning the sheet in the printing apparatus can be omitted.
  • the printing apparatus can be arranged especially as a printer and/or copying machine.
  • the sheet can be printed by the printing apparatus by means of laser printing, needle printing, ink-jet printing and/or thermoprinting.
  • the sheet is a thin-layered medium suitable for receiving a print image.
  • the sheet suitable for printing in the printing apparatus is usually provided with a sheet thickness of between 0.01 mm and 1 mm.
  • the sheet can be arranged especially as a sheet of paper which can also be designated as paper. Similarly, the sheet may be made of plastic and therefore be designated as a foil.
  • the sheet can especially have a surface size of between A6 and A00 or can be cut with standardized dimensions or special dimensions. Sheets are usually arranged to be rectangular, with paper cassette 1 being arranged especially for rectangular sheets.
  • a filling-level boundary area 34 of the filling-level limiting apparatus 3 which can come into contact with the upper surface 21 and a paper stack support 11 are arranged in a third position 13 closer to one another than in a fourth position 14 of the same.
  • the third position 13 - as shown in Fig. 1 - can be arranged to a frame 12 of the paper cassette 1 by means of a relative movement of the filling-level limiting apparatus 3 and/or to a frame 12 of the paper cassette 1 by a relative movement of the paper stack support 11.
  • Filling-level limiting apparatus 3 and paper stack support 11 are arranged in their third position in the loading position of the paper cassette 1.
  • Filling-level limiting apparatus 3 and paper stack support 11 are arranged in their fourth position 14 in the readiness position of the paper cassette 1.
  • the distanced arrangement of the filling-level limiting apparatus 3 to the upper surface 21 of the stack of sheets 2 can be achieved especially in such a way that the filling-level limiting apparatus 3 is moved for this purpose relative to the paper stack support 11 of the paper cassette 1. It can be provided advantageously that the filling-level limiting apparatus 3 is arranged in a first position 31 in the loading position of the paper cassette 1, and that the filling-level limiting apparatus 3 is arranged in a second position 32 in the readiness position of the paper cassette 1.
  • the filling-level limiting apparatus 3 and especially the filling-level boundary area 34 of the filling-level limiting apparatus 3, is in contact with the upper surface 21 of the stack of sheets 2.
  • the filling-level limiting apparatus 3 and especially the filling-level boundary area 34 of the filling-level limiting apparatus 3, is spaced from the upper surface 21 of the stack of sheets 2.
  • the motion between the first position 31 and the second position 32 can especially be arranged as a movement of translation, with the filling-level limiting apparatus 3 being moved in a substantially translational way.
  • said translational movement can be aligned parallel to a normal line 22 to the upper surface 21 of the stack of sheets 2. It is advantageous in this respect that the filling-level limiting apparatus 3 can be lifted off the upper surface 21 of the stack of sheets 2 with minimal translational movement.
  • the filling-level limiting apparatus 3 comprises a lateral guide means 36 for lateral guidance of the stack of sheets 2.
  • the lateral guide means 36 can be provided especially for lateral guidance of the stack of sheets 2 both in the first position 31, especially also in the third position 13, as well as in the second position 32, especially also in the fourth position 14, with the stack of sheets 2 being laterally guided by means of a lateral guide means 36 which is comprised by the filling-level limiting apparatus 3.
  • the lateral guide means 36 can preferably be arranged in a substantially planar way.
  • the filling-level limiting apparatus 3 and/or the paper stack support 11 can be moved parallel to the substantially parallel lateral guide means 36 between the first position 31 and the second position 32, with the distance of the lateral guide means 36 to the stack of sheets 2 not changing. It is advantageous that despite the motion of the filling-level limiting apparatus 3 the lateral guidance of the sheet remains substantially the same both in the loading position as well as in the readiness position of the paper cassette 1.
  • the filling-level boundary area 34 of the filling-level limiting apparatus 3 can be lifted off the upper surface 21 of the stack of sheets 2 by means of the release device 5, with the release device 5 being provided for moving the filling-level limiting apparatus 3 from the first position 31 to the second position 32 during the displacement of the paper cassette 2 from the loading position to the readiness position.
  • the release device 5 is shown schematically in Fig. 2 .
  • the guide surface 35 can advantageously be moved relative to the release device 5 and brought into contact with the release device 5.
  • the guide surface 35 as shown in Figs.
  • the filling-level limiting apparatus 3 in the loading position will become arranged in the first position 31 automatically, which means without any manual action on the part of a user of the printing apparatus, for which purpose a pretensioning element 33 can advantageously be provided.
  • the release device 5 is arranged on a housing 6 of the printing apparatus and, in the readiness position of paper cassette 1, is provided for making contact with the filling-level limiting apparatus 3, especially a guide surface 35 of the filling-level limiting apparatus 3.
  • the filling-level limiting apparatus 3 can thus be moved easily from the first position 31 to the second position 32, with the filling-level limiting apparatus 3 being moved by means of a release device 5.
  • the release device 5 can be arranged as a guide rib, hump and/or as a cam, so that the motion of the filling-level limiting apparatus 3 can be guided in a simple and reliable way, with this occurring without any manual intervention during the displacement of the paper cassette 2 from the loading position to the readiness position and vice-versa.
  • the release device 5 in the readiness position of paper cassette 1, is arranged as a counter-bearing to the filling-level limiting apparatus 3, especially to the guide surface 35 of the filling-level limiting apparatus 3, the release device 5 can also be designated as a counter-bearing.
  • the pretensioning element 33 is connected with the filling-level limiting apparatus 3 and the paper cassette 1. It can advantageously be provided that the pretensioning element 33 pretensions the filling-level boundary area 34 in the direction towards the paper stack support 11 and that the pretensioning element 33 tensions the release device 5 in the readiness position, i.e. it is moved in a direction against the direction of relaxation of the pretensioning element 33.
  • the release device 5 is arranged in a contact-free manner relative to the filling-level boundary area 34, the pretensioning element 33 relaxes, through which the filling-level limiting apparatus 3 is arranged substantially automatically in the first position 31 through the pretensioning element 33 and moves substantially automatically from the second position 32 to the first position 31.
  • This substantially automatic arrangement of the filling-level limiting apparatus 3 in its first position 31 can occur in an especially simple and reliable manner when the pretensioning element 33 is arranged between the paper stack support 11 and the guide surface 35.
  • the pretensioning element 33 can especially comprise a metal spring, and can preferably be arranged as a metal spring.
  • the filling-level limiting apparatus 3 can comprise a stop element which acts in the loading position and which is provided that the filling-level limiting apparatus 3 cannot displace from the first position 31 in the direction towards the second position 32 during the filling of the paper cassette 4.
  • the stop element can be arranged advantageously between the paper stack support 11 and the guide surface 35, thus ensuring a specific minimum distance between the paper stack support 11 and the guide surface 35.
  • the stop element is ineffective in the readiness position.
  • the stop element can be moved out of the intermediate space between the paper stack support 11 and the guide surface 35, through which the filling-level limiting apparatus 3 can be displaced beyond the first position 31 in the direction towards the second position 32.
  • the moving out of the stop element can advantageously occur by means of a counter-bearing, especially a counter-bearing comprised by the housing, which is arranged on the housing of the printing apparatus.
  • the stop element can be displaced or twisted, and tilted for example, when moving the stop element out of the intermediate space between the paper stack support 11 and the guide surface 35.
  • the filling-level limiting apparatus 3 is arranged in a firmly positioned way relative to the frame 12 of the paper cassette 1, and that the paper stack support 11 is arranged to be movable relative to the frame 12 of the paper cassette 1, especially relatively displaceable to the frame 12.
  • Such relative motion between the filling-level limiting apparatus 3 and the paper stack support 11 can occur especially in the same manner as described above, with the filling-level limiting apparatus 3 being arranged in a firmly positioned way relative to the frame 12 and the paper stack support 11 being moved.
  • the second embodiment of paper cassette 1 can be operated by means of a method in which it is provided that the paper stack support 11 which is arranged in the loading position of the paper cassette 1 in the fifth position is moved to a sixth position when displacing the paper cassette 1 from the loading position of the paper cassette 1 to the readiness position of the paper cassette 1, with the filling-level limiting apparatus 3 and the paper stack support 11 - relatively to each other - being arranged in the loading position in the third position 13 and the filling-level limiting apparatus 3 and the paper stack support 11 - relatively to each other - being arranged in the readiness position in the fourth position 14.
  • the release device 5 is provided for cooperating with the paper stack support 11.
  • the release device 5 can especially be arranged on the housing and disposed thereon in such a way that during the displacement of the paper cassette 1 to its readiness position the release device 5 moves the paper stack support 11 away from the filling-level boundary area 34.
  • the pretensioning element 33 can especially be provided which can be arranged and/or disposed especially according to the above explanations made in connection with the pretensioning element 33.
