Definitions

  • the invention relates to a printing material container, in particular an ink cartridge or a laser cartridge, for insertion into a container receptacle of a recording device or an adapter for receiving and / or contacting a printer material container in a recording apparatus according to claim 1, and a holder for a circuit board to a printing material container according to Claim 16.
  • printing material containers with a printing device on the container provided on the contact elements with the printing device.
  • These contact elements may serve to detect certain states or to transmit information or commands between the printing device and the printing material container, for example.
  • the printing material container may be an integrated circuit comprising a memory having access to the via contact elements.
  • the contact elements can be used to detect an inserted cartridge, to control any provided electrical or optical elements, such as those used for level detection or integrated print heads of ink cartridges for ejecting ink droplets.
  • Object of the present invention is to propose a printing material container or adapter for receiving and / or contacting a printing material container, a allows comparatively reliable and secure contacting of the printing material container or adapter in a container receptacle of a recording device.
  • a signal transmission of an electrical signal should be able to take place without interference.
  • Another object of the present invention is to ensure the contact during operation, so that slipping or displacement of the printer-side and cartridge-side contacts during operation, even with possible shocks is not possible.
  • Such a printing material container or adapter for a printing material container for insertion into a container receptacle of a recording device with device contacts is inserted substantially along an insertion direction Z in the printer.
  • a circuit board located on a first side of the printing material container, which is opposed to the device contacts in the inserted state, a circuit board, which is a printed circuit board, having a first surface and a second, the first opposing surface.
  • the first end of the board both surfaces at least partially spaced from an outer surface of the printing material container or adapter and at least one, but preferably on the first and the second surface provided at least one contact portion on a spaced portion of the surface for contacting with at least one device contact, wherein the board is pivotally arranged in and / or against the insertion direction Z.
  • the pivoting movement in addition to the motion vector directed in or against the Z direction, also includes a motion vector directed in or against the direction G, for example parallel to the x axis or parallel to the x, z plane, so that the circuit board also in and / or direction G is pivotable.
  • the x, y, z coordinates correspond to a conventional orthogonal coordinate system in which the Z direction is determined by the insertion direction. In the case of, for example, essentially cuboid printing material containers, then x and / or y coordinates can be aligned parallel to one or two side surfaces (see also FIGS.).
  • the board can be arranged so that it is pivoted when inserting initially by resiliently projecting device contacts a first contact row against the insertion direction from its intended or set position. At the same time a first end moves, or the corresponding edge of the board in or against the direction of the example. Linearly arranged on the same z-coordinate device contacts. The latter feathers, either through the edge of the board itself or through guide elements discussed below in the holder of the board, in a printer-side contact block, so that the board edge or the guide elements can slide over the first row of contacts. Subsequently, the board can be fixed or clamped in the end or printing position between the first, now again at least partially rebound and a second, adjacent and substantially parallel to the first row contact row.
  • the board can be made elastic at least in the region of the first end or consist of elastic material. It can also be largely or even completely elastic or largely or completely made of elastic material.
  • the device or printer contacts may be formed from two immediately adjacent, parallel rows of contacts, which are designed resiliently against the contacts of the printing material container. They should be designed so that between the contact rows, for example, a V- or U-shaped, positioning or clamping position is formed, so that the board edge can be covered with the contacts.
  • at least two device contacts are required with an offset device contact arrangement, with an offset device contact arrangement, wherein the single contact, for example, the 1st row / side between the contacts of the 2nd row / page is.
  • individual Device contacts are replaced by support ribs or, for example, all device contacts on one side, by a support or terminal block.
  • the board may include, at least in a portion of a spaced portion of the surface, one or more fingers that have contact pads on the first and / or second surfaces to form a contact portion where the device contacts contact the finger.
  • the board may also be formed finger-shaped in the entire region of the first end, wherein the fingers, either on both sides or preferably alternately on the first and second surfaces, contact portions.
  • contacts or contact portions disposed on opposite surfaces are generally not interconnected, or for specific purposes alone, which alone reduces the likelihood of shorting during the insertion process. This is especially true when two-row arranged device contacts spaced apart not only with respect to the insertion direction Z from each other are arranged to contact the contact portions on the first and the opposing second surfaces but are also offset with respect to a direction Y which is perpendicular to the insertion direction Z and perpendicular to the direction G and X, respectively.
  • adjacent fingers contacted only from below or from above they are by the spring force of the contacts and / or a resilient employment of the board against the contacts, alternately with respect to the insertion positive or negative, for example, up / forward or after bent down / back.
  • the entanglement of the fingers essentially leads to a single-row alignment of the contact sections, ie the points of contact of the device or printer contacts with the contacts of the board.
  • the board itself even without trained fingers between the two device contact rows be wavy clamped, so that even in this case the contact sections substantially single row, for example, with respect Direction Z be arranged at the same coordinate or height.
  • electrodes may be arranged between two contacts adjacent to one another on the same surface, for example in a region which is not spaced from an outer surface of the printing material container or the holder.
  • such electrodes can be used to prevent short circuits caused by, for example, conductive ink splashes.
  • the board is fixedly arranged in a holder pivotally mounted on or in the first side, wherein both surfaces are at least partially spaced from an outer surface of the holder in the region of a first end of the board when inserting the cartridge to the device contacts.
  • the holder can be pivotable about an axis Y, which is aligned at right angles to the insertion direction Z and at right angles to the direction X or G.
  • at least one guide element in particular at least one guide recess may be provided on the holder and / or on the printing material container or adapter in order to receive a corresponding protruding device contact.
  • at least one guide nose in particular a nose limiting the guide recess laterally, can be provided.
  • the guide nose is advantageously arranged so that the board is guided or clamped with inserted cartridge between the guide nose and device contact.

  • the disadvantage of such arrangements is that by a lateral deflection of the contact springs, for example. When inserting the cartridge, incorrect contacts are not sure to exclude.
