Definitions

  • the present invention relates to an ink cartridge for ink jet printers or the like. Recording apparatus according to the preamble of claim 1.
  • printers have means which determine what the level of the ink cartridge is, in particular determine whether the ink cartridge is empty or will soon be empty, in order then to prevent further printing. It is indicated that a cartridge exchange is required.
  • the ink cartridge has a level indicator which comprises an opaque or alternatively light-reflecting lug, the lug being connected to a float arranged inside the ink cartridge or the housing thereof, such that the lug is either in or out of the range with decreasing level in the printer arranged light barrier is movable.
  • the flag may be arranged on a rotatably mounted float device. If a predetermined level is reached, the light barrier is released, ie, the light beam passes unhindered from the light transmitting part through the cartridge to the light receiver part. This triggers a predetermined procedure indicating that cartridge replacement is required.
  • the level detection means comprise a first arranged outside the cartridge and the light emitting part facing light beam deflection surface, within the cartridge depending on the fill level by ink wettable or ent Missionbares deflection prism, and a second arranged outside the cartridge and the light receiver part facing light beam -Umlenk Chemistry.
  • the filling level falls below the deflecting prism, it is dehusked and the light beam entering the deflecting prism is deflected via a total reflection, so that it emerges again from the deflecting prism.
  • the exiting light beam is then directed through the second light beam deflection surface into the light receiver part. Then again, the signal already mentioned that the cartridge is empty and must be replaced.
  • first and second light beam deflection surface must each be provided with a separate light-reflecting surface.
  • the corresponding surfaces are provided in the prior art with high-gloss aluminum foils.
  • the effort for the production of the first and second light beam deflection surfaces is correspondingly large. Also, these deflection can be easily damaged by improper treatment and thus made unusable.
  • the present invention is therefore based on the object to improve the latter version of an ink cartridge to the effect that the level detection means, in particular light beam deflection means can be made easier with the result that the ink cartridge is generally easier and cheaper to manufacture.
  • the first and second light beam deflection surfaces are an integral part of the cartridge.
  • the corresponding triangular prisms are produced together with the cartridge or the cartridge housing as an injection molded part.
  • the light beam deflection surfaces are within the triangle prisms, so no longer on the outside, so that separate light-reflecting measures are unnecessary.
  • the first and second triangular prisms are each positioned so that the sides of the catheter each extend perpendicular to the incident and outgoing light beam and the light beam deflection takes place on the hypotenuse side.
  • the triangular prisms in cross-section each define an isosceles right-angled triangle where the adjacent and opposite cathets are the same length.
  • the two triangular prisms can be arranged either at the same or different height above the deflecting prism disposed within the cartridge.
  • an ink outlet is formed on the front side of the cartridge near the bottom thereof.
  • the level detection means are then arranged above the same.
  • an extension of the ink receiving space projecting forward over the front of the cartridge is formed, the upper side of which comprises the deflecting prism so that the tip opposite the hypotenuse side is directed into the extension.
  • the cross-section of this deflecting prism also preferably defines an isosceles right-angled triangle.
  • the emitted light beam from the light emitting part of the light beam is deflected via the first triangular prism with the aid of total reflection on the deflection prism arranged underneath, which is in sufficiently full ink cartridge in contact with the ink.
  • the light beam is then absorbed in the ink.
  • the second triangular prism which is assigned to the light receiver part.
  • the light beam is then diverted to the light receiver part via this second triangular prism. This triggers a signal indicating that the ink cartridge is largely empty and needs to be replaced.
  • the arranged within the ink cartridge deflecting prism is wetted with ink, the light beam is not deflected there, but only deflected into the ink and absorbed there. If the filling level drops so far that the deflecting prism is dewaxed, the light beam is deflected via the total reflection then taking place there to form the second triangular prism.
  • both the known float device and the separate reflective surfaces which must be created by appropriate measures, either by the application of light-reflecting films or the vapor deposition of a light-reflecting layer omitted.
  • Fig. 1 illustrated ink cartridge is indicated by the reference numeral 10.
  • This has a flat parallelepiped shape with an in mounting direction front or front 11, top 12, bottom 13, back 14 and front and rear flat side 15 and 16.
  • On the front side 11 is near the bottom 13 an ink outlet 17 and near the top 12th an air inlet 18 is formed.
  • Ink outlet and air inlet are on the front side 11 before. Since these are design features known per se, a more detailed description is unnecessary at this point. Ink outlet and air inlet are associated with corresponding printer side ports.
  • the mounting direction is in Fig. 1 marked with the arrow 19.
  • first light beam deflection surface which is arranged outside the cartridge 10 and faces a light transmitting part, not shown here, in the form of a first Triangular prisms 20, a within the cartridge 10 depending on the level by ink or entsobenbares Umlenkprisma 21 and a second disposed outside the cartridge 10 and a not shown here Lichtempfteil facing light beam deflection within a second triangular prism 22.
  • the two triangle prisms 20, 22nd are each positioned so that the Kathetencount 23, 24 and 25, 26 (see FIGS.
  • FIGS. 2 and 3 each extend perpendicular to the incident light beam 28 and the outgoing light beam 29, and that the light beam deflection takes place on the hypotenuse side 30.
  • FIGS. 2 and 3 are light emitting part with the reference numeral 31 and light receiver part indicated by the reference numeral 32. As already mentioned, these two parts are designed on the printer side.
  • the first and second triangular prisms 20, 22 are arranged at the same height above the deflecting prism 21 arranged inside the cartridge 10.
  • the two triangular prisms 20, 22 and also arranged within the cartridge 10 deflecting prism 21 are further integral to each of the cartridge 10 and the cartridge housing. They are thus integrally connected to the cartridge housing and preferably made as an injection molded part.
  • the prisms could also be designed as separate insert components.
  • Fig. 2 the beam path of the light emitted by the light emitting part 31 light beam at sufficiently high level of the ink cartridge 10 is shown.
  • the light beam 28 is deflected within the first triangular prism on the Hypotenusenseite 30 down.
  • the deflection prism 21 is wetted with ink. As a result, there is no further deflection of the light beam. This is instead deflected into the ink 27 and absorbed by it.
  • the printer-side light receiver part receives no signal. This indicates that the ink cartridge is still full. Only when the level drops so far that the Umlenkprisma 21 is de-meshed, there is a total reflection accordingly Fig. 3 such that the light beam is deflected to the second triangular prism 22. There, the light beam undergoes a further deflection towards the printer-side light receiver part 32. There, too, a total reflection takes place, namely within the second triangular prism 22 on its hypotenuse side. The printer then receives a light signal, which is a Interruption of the printing process and an indicator triggers that the ink cartridge must be replaced by a new one.
  • a guide web 35 is formed, which is narrower than the top or the distance between the front and rear flat side 15, 16. Furthermore, the upper guide web extends 35 not over the entire length of the ink cartridge or top 12. The front 11 facing the end of the upper guide bar 35 is tapered towards the top 12 and formed like a ramp.
  • a guide web 36 is formed, whose width is smaller than the distance between the front and rear flat side 15, 16. This guide web starts at the front side 11 and extends over about half the length of the ink cartridge 10. This is followed by a Recess 37, which extends to a rear side 14 extending projection 38 back. Immediately before the projection 38, the recess 37 is additionally recessed. This additional recess is identified by the reference numeral 39.
  • the projection 38 and the recess 39 serve to engage a printer side arranged pivot lever, by means of which the ink cartridge can be pulled out of the mounting position, and indeed until they are easily gripped between two fingers and completely pulled out of the printer or from the corresponding receptacle can be.
