Definitions

  • the invention relates to a paper transport device according to the preamble of patent claim 1.
  • the transport devices are designed so that they can be replaced without special aids. This is e.g. B. necessary if single sheets are to be written with the printing device.
  • the transport device for continuous paper including its paper tractors and the associated motor drive, has previously been removed from the printing device and replaced by a specific transport device designed for single sheets.
  • a combined transport device for continuous forms and account cards for writing, booking and similar machines contains a paper guide channel arranged above the writing area and ensuring a vertical supply of account cards and pressure elements arranged in the area of the paper guide channel and pressing the single sheet against a drive shaft resiliently after insertion into the paper guide channel.
  • this known device has an endless paper tractor combined with the vertical account card feed channel, which is integrated into the entire device immovably, that is to say not pivotably, in order to be able to also print endless forms.
  • the existing platen roller, the paper tray and the pressure rollers must be removed from the machine beforehand, which complicates the exchange.
  • CH-PS 243 855 In order to ensure lateral guidance of individual sheets during insertion into a paper transport device of a typewriter and to be able to adapt the guide to the different paper widths, it is known from CH-PS 243 855 to provide a guiding device with displaceable side elements on the typewriter.
  • DE-OS 2 615 788 describes a paper feed device for a printer, which consists of a transport device for continuous paper with two paper tractors.
  • the paper tractors are swivel-mounted without the tractors being supposed to bring about paper in this second position.
  • the object of the invention is to design a paper transport device of the type mentioned at the outset in such a way that it can be converted in a simple manner for the transport of single sheets and that when writing sets of forms with multiple copies, there is no offset between the copies.
  • the known transport device for continuous paper can thus be moved according to the invention into a transport device for single sheets or
  • the transport device for continuous paper - as claimed - is pivotally mounted in the printer.
  • the vertical paper transport channel between the transport device and the writing point thereby results in the paper being guided vertically past the writing point. This means that when writing continuous form sets or individual sheets fed via the single sheet feeder, there is no offset between the copies.
  • paper transport shafts forming a lower roll feed are arranged below the writing area, e.g. are favorable for the transport of single sheets
  • the transport of these paper transport roller shafts is likewise carried out by means of a corresponding gear coupling, likewise via a single motor assigned to the paper tractors.
  • the printing device shown schematically in FIG. 1 contains a wire dot print head 10, which is moved line by line along a recording medium with the aid of a motor 11 in writing operation.
  • This record carrier can either consist of continuous paper or, with the appropriate addition, of single sheets.
  • the paper is moved via paper tractors 12 along the writing point via a pressure bar 13 serving as a platen.
  • the paper tractors are connected on the one hand via a guide bar 14 and on the other hand via drive shafts 16 coupled to a motor 15.
  • the paper tractors 12 can be moved along the guide bar 14 and the drive shafts 16.
  • the entire transport device for continuous paper with its tractors and the associated motor 15 mounted on the side can be pivoted within the printer housing.
  • the operation with continuous paper is assigned the horizontal position of the transport device shown in dashed lines and the operation with single sheet described in more detail below is the vertical position of the transport device.
  • a push-on transport device for single sheets is placed on this transport device in the vertical position of the transport device for continuous paper. It consists of two side elements 18 and 19 which can be symmetrically configured and laterally displaced with the aid of latching elements 17 and which can be slid onto the guide bar 14, the side elements 18 and 19 being designed in the manner of a funnel-shaped plastic cassette with recesses 20, with paper pressure rollers 21 mounted therein via spring elements 22 .
  • these spring elements 22 press a single sheet 23, which is inserted into the side elements as shown in FIG. 1, against the lower drive shaft 16 of the paper transport device, which likewise has paper pressure rollers 24.
  • the entire paper transport channel is now designed such that, in the vertical position of the paper transport device, the paper channel is located directly above the writing point, as shown in FIGS. 5 and 6.
  • the record carrier be it single sheet or continuous paper
  • this configuration supports and facilitates feed of the recording medium in both feed directions.
  • continuous paper 25 can be moved both forwards and backwards with the help of the paper tractors 12 around the pressure beam 13.
  • Such forward and reverse operation is e.g. an advantage when filling out forms.
  • a single sheet 23 can be transported in the same way with the attached transport device for single sheets.
  • the printing device contains a lower roller feed 26 from two paper transport shafts, the lower roller feed 26 likewise being driven by the motor 15 via a belt transmission 27, as shown in FIG. 3. Due to the small distance between the caterpillars of the paper tractors and the printing point (needle print head 10), a forward and backward movement can be easily accomplished here.
  • the guide of the continuous paper shown in FIG. 6 with a paper feed from the back combined with vertical feeding past the printing point is also also the guide of the continuous paper shown in FIG. 6 with a paper feed from the back combined with vertical feeding past the printing point.
