Definitions

  • the invention relates to a printer with an exchangeably insertable ink ribbon cassette, which has a storage space for an ink ribbon and a transport device for the ink ribbon which can be driven by an electric motor via a reduction gear.
  • the invention has for its object to design the arrangement of the type mentioned in such a way that the susceptibility to repairs of the printer is reduced.
  • the solution is achieved in that the electric motor and the reduction gear are arranged in a drive housing which is firmly integrated into the housing of the ink ribbon cassette and in that means are provided for establishing a power connection from the motor to the printer by means of a detachable contact connection.
  • the electric motor and its reduction gear are no longer part of the printer but of the cassette. In the event of a defect in these components, only the then defective cassette needs to be replaced by an operator, the help of a skilled technician being no longer required.
  • the effort for a drive assigned to a cassette is considerably less than when assigned to the printer, because it only has to be dimensioned for the relatively short life of a cassette.
  • the initial cost of a printer including a cartridge is reduced.
  • the ribbon cassette according to the invention must be electrically connected to a printer. This is possible in a simple manner in that the contact connection through the Cassette arranged connector takes place, which are inserted into associated mating connectors of the printer when the cassette is inserted into the printer.
  • the electrical connection can be made automatically without additional effort in that resiliently excellent contact elements, which are electrically connected to the electric motor, are provided from a cassette wall, which contact the associated mating contact surfaces of the printer with the cassette inserted in a current-conducting manner.
  • the contact elements of the cassette are advantageously arranged in a plane parallel to their direction of insertion.
  • the corresponding electrical contact surfaces can slide to a certain extent relative to one another, so that tolerance differences in the cassette position may be permitted without impairing the power connections.
  • the contact surfaces of the cassette are arranged in a plane orthogonal to the pivot axis in the vicinity of the pivot axis. A displacement of the contact connection within particularly narrow limits is sufficient.
  • FIG. 1 a section of an ink ribbon 3 runs in the area between side arms 1 and 2, a large length of which is stored in a storage space 4.
  • the ink ribbon 3 is moved further in the direction of the arrow 5 by means of a drive which is provided in the integrated drive housing 6.
  • FIGS 2 to 4 show details of a drive designed according to the invention for a ribbon cassette.
  • a motor 12 operated with a DC voltage of less than 12 volts drives its belt wheel 13 via the toothed belt 14 the gears 15 and 16 of a reduction gear.
  • the gearwheel 16 meshes with the transport roller 23, during the rotation of which the ink ribbon 3 clamped between the transport rollers 23 and 24 is pulled.
  • the gears 15 and 16 can advantageously be molded onto the bottom wall of the drive housing 6.
  • the connecting lines 17 and 18 coming from the electric motor 12 are connected to sliding contacts 19 and 20 which protrude from spring arms 21 and 22 of a contact carrier 25.
  • the sliding contacts 19 and 20 are arranged in the immediate vicinity of the axis of rotation 11, so that their sliding movement when pivoting the ribbon cassette is as small as possible.

Claims (5)

  1. Imprimante munie d'une cassette de ruban encreur insérable de façon remplaçable, qui présente un espace récepteur pour un ruban encreur et un dispositif de transport pour le ruban encreur, pouvant être entraîné par un moteur électrique via un dispositif démultipticateur, caractérisée en ce que le moteur électrique (12) et le dispositif démultiplicateur (15, 16) sont montés dans une boîte d'entraînement (6) intégrée à demeure au boîtier de la cassette de ruban encreur et que des moyens (7 à 10) sont prévus pour réaliser une connexion électrique du moteur (12) à l'imprimante via un dispositif de contact séparable.
  2. Imprimante selon la revendication 1, caractérisée en ce que le dispositif de contact est réalisé par des organes d'enfichage prévus sur la cassette qui sont insérés dans des douilles de contrepartie qui leur sont affectées dans l'imprimante lorsque la cassette est insérée dans celle-ci.
  3. Imprimante selon la revendication 1, caractérisée en ce que des éléments de contact (7,8 ou 19 à 22) connectés électriquement au moteur et faisant saillie élastiquement à partir d'une paroi de la cassette sont prévus et viennent en contact avec des surfaces de contact antagonistes correspondantes (9, 10) dans l'imprimante pour laisser passer le courant lorsque la cassette est insérée en place.
  4. Imprimante selon la revendication 3, caractérisée en ce que les surfaces de contact (19 à 22) de la cassette sont disposées dans un plan parallèle à la direction d'insertion.
  5. Imprimante selon la revendication 4, caractérisée en ce que les surfaces de contact (19,20) de la cassette sont disposées, dans le cas d'une cassette montée à pivotement sur un axe de pivotement (11) fixé par rapport à l'imprimante, dans un plan perpendiculaire à l'axe de pivotement (11) au voisinage de celui-ci.
