Definitions

  • the present invention relates to a method of loading a printing media into printers and also to a printer which uses the said method and to a combined push-button/deflector device for use in the said method.
  • a problem which frequently arises in printers of this type is that, given that the manual guiding of the sheet of printing media or of the roll of printing media has to be carried out at a considerable distance from the front edge of the printing media, it is difficult to achieve good alignment of the printing media and, in many cases, this delays the operation of the printer when this operation has to be repeated, since the printer cannot tolerate appreciable deviation of the printing media from the theoretical position.
  • US 5,379,998 describes an apparatus which may be used in order to manually feed sheet print media into a printer.
  • This document teaches to manually align the sheet along a media guide provided on the apparatus. The sheet is then fed towards the printer when the operator activates the feed mechanism, using a switch located near to the media feed path.
  • the teaching of this disclosure is suitable exclusively for aligning cut sheets (as opposed to media wound on a roll) and furthermore, only sheets which are small enough to be aligned with one hand.
  • the teaching of this disclosure is suitable for aligning neither media which is wound on a roll, nor media which is too wide to be satisfactorily aligned with one hand.
  • the present invention relates to a method which is intended to solve the problem mentioned above by providing means for considerably simplifying the initial loading of the printing media into the printer so that the misalignments mentioned do not occur.
  • Another subject of the present invention consists of the disclosure of a printer which incorporates means for implementing the method of the present invention.
  • Yet another subject of the present invention consists of the disclosure of a combined device including a deflector and guide for the printing media upon its output from the printer and a push-button for operation in a printer formed in accordance with the present invention.
  • a basic concept of the present invention lies in the fact that the method of loading the printing media into the printer provides for the operation of the rollers for advancing the printing media to be activated manually by the operator himself at the moment when the said printing media is introduced into the printer and at the moment when the operator estimates that the sheet of printing media is correctly positioned, without deviation.
  • This basic concept prevents the present problem that, once the printing media has been introduced, the entrainment rollers advance the printing media at once, almost without there being time for the operator to assess the alignment of the printing media, so that the operator has very little chance of manoeuvring to ensure beforehand that the printing media is supplied correctly without deviation.
  • means are provided in the printer for enabling the operator to introduce the end of the printing media into the machine whilst observing sufficiently precisely the position of the front edge of the printing media during its introduction into the machine in order to ensure that it is correctly positioned, the entrainment rollers for the printing media being stationary during this time and being set in motion only by manual action by the operator after the printing media has been put in place and only at the moment when the operator estimates that the printing media is correctly positioned.
  • the manual action by the operator consists of the operation by the operator of a push-button which starts the operation of the rollers which entrain the printing media towards the interior of the machine.
  • An important feature of the present invention consequently consists of the arrangement of the push-button for manual operation by the operator in a position which is convenient for its operation, bearing in mind that the operator is in a position to present the printing media and to align it in the input region of the printer. For this reason, the arrangement of a push-button in a region as close as possible to that in which the operator's hands are situated during the operation to introduce the printing media into the machine is preferable.
  • the printer is characterized in that it has means for the manual operation of the printing-media feed rollers in order for the print cycle to be able to start, with regard to the activation of the remaining members of the machine, the printer having separate manual means for setting the printing-media feed rollers of the printer in motion independently and by manual operation.
  • the printer has a system for supplying the drive motor of the printing-media feed rollers, the initial activation of the system prior to a printing cycle being brought about by means of a manually-operated push-button the operation of which is essential for initially setting in motion the drive motor of the said printing-media feed rollers.
  • the position of the said push-button may vary according to the precise configuration of the printer and its manner of operation, but a preferred arrangement consists of its incorporation in a position very close to that in which one or both of the operator's hands are situated at the moment when the printing media is introduced into the printer.
  • the printer has a combined device for deflecting the printing media at the output, once the printing operation has been carried out, the device being disposed in the front portion of the printer partially covering the printing media in the input region and incorporating the manual push-button for activating the printing-media feed rollers.
  • the said combined device can preferably also support the device for detecting the presence and/or absence of the laminar printing media.
  • the present invention is applicable to a printer, indicated 1, into which the printing media 2, which may be constituted by a roll or by individual sheets of printing media or other similar material, is fed.
  • the front guide platen 3 for the printing media 2 has, on one side, an alignment of reference marks 4 which may be formed by small holes, for enabling the corresponding side edge 5 of the printing media 2 to be aligned at the moment when it is introduced into the front portion of the printer 1.
  • the manual feeding operation for loading the printing media into the machine therefore involves the alignment of the edge 5 with the reference line 4, see Figure 2, the operator ensuring that the front edge of the printing media is suitably arranged, without deviation.
  • the push-button 6 is incorporated in a combined assembly 7 which acts as a deflector for the output of the printing media and which has a removable front frame 8 for permitting the said guiding, the assembly being mounted above the input for the printing media into the machine, as indicated in the drawings. This arrangement considerably facilitates the manual operation of the activation push-button.
  • the printing media can proceed from a roll 10 to the guide plate 11 of the printer beneath the deflector and push-button assemblies 12, and is then guided by the main roller 13 towards the output path 14.
  • the combined deflector and push-button assembly comprises a narrow body 7 which is disposed at the input to the copier, above the printing media during its input into the printer, and which has an upper face for guiding the printing media upon its output from the printer, with a removable front frame 8 and central push-button 6, the assembly being mounted above the printing media upon its input into the printer so that the lever 15 of the detector for detecting the presence or absence of the printing media is disposed in the lower portion of the said assembly, acting on the face of the printing media which will not receive the printing.
  • the frame 8 has two arms 16 and 17 which are intended to extend the area for guiding the printing media and which can be coupled releasably to the body 7 of the deflector by means of lateral projections 18 and recesses 19 in the body 7, or by another suitable arrangement.
  • the switch 20 operated by the push-button and the detector 21 for detecting the presence or absence of the printing media, which is operated by a pivoting element 22, are disposed inside the assembly comprising the deflector 7 and the push-button 6, as can be seen in Figure 9.
  • the body 7 of the deflector and push-button assembly comprises two component parts 21 and 22 which fit into one another and include the elements mentioned above and, in particular, the push-button 6 which is coupled in a housing 23 by means of a region of matching shape 24, and which is pivotable on the said housing.
