Definitions

  • the invention relates to a paper transport device for printing devices according to the preamble of patent claim 1.
  • Such a paper transport device is known from JP-OS 58-142 877.
  • the continuous paper In the operation with continuous paper, the continuous paper is guided over pin wheels and pulled by the platen roller in frictional engagement.
  • An electro-optical positioning device assigned to the pin wheels emits positioning signals when the continuous paper is moved.
  • the positioning signals for a specific paper feed are compared with the control steps of the stepper motor driving the paper roll and the feed is corrected in the event of deviations.
  • JP-OS 60-21 275 a paper transport device for continuous paper and single sheets can be found, in which an electro-optical scanning device is arranged in the area of the platen roller. With the paper feed drove the paper over the scanner triggers an electromagnet, which presses the paper against the platen roller.
  • the object of the invention is to provide a paper transport device of the type mentioned at the outset which makes it possible to transport both single sheets and continuous paper reliably and in a positionally accurate manner and which enables the continuous paper to be inserted in a simple manner.
  • an electro-optical scanning device which compares the feed of the incoming paper, be it continuous paper or single sheets with that of the drive element (stepper motor) of the platen roller in front of the removable setpoint, and controls or corrects the feed as a function thereof.
  • the pin wheels are equipped with a locking mechanism that emphasizes the direction of rotation couples. This enables the continuous paper to be moved in the transport direction, but the paper is strongly inhibited by the locking mechanism in the opposite direction. However, this resistance can be overcome with more force.
  • a pivotable paper guide flap is provided, the surface of which is designed as a guide surface for the continuous paper and which has on its inner surface a guide attachment for the continuous paper, which forms a paper feed channel for the pin wheels together with the printer frame, which is designed such that the continuous paper with its edge perforations has an intended wrap angle around the pin wheels.
  • the paper transport device shown schematically in FIG. 1 for a typewriter or office machine working according to the principle of the ink printer contains a motor-driven platen roller 1 with an associated stepping motor 2, which has a recording medium made from single sheets 3 or continuous perforated paper 4 in a paper guide channel 6 formed by paper pressure rollers 5 moved along by an ink writing head 7.
  • the ink writing head 7 is arranged in a manner not shown here on a printer carriage and is moved line by line in a known manner along the recording medium during the writing operation.
  • the continuous paper and the individual sheets are driven by frictional engagement between the paper pressure rollers 5 and the motor-driven platen roller 1, the paper pressure rollers themselves also being able to be motor-driven.
  • the printing device shown is suitable for operation with single sheets 3 as well as for operation with continuous paper 4.
  • a paper guide channel 8 for continuous paper and another paper guide channel 9 for single sheets lead into the paper guide channel 6 between the platen roller and paper pressure rollers 5.
  • Upstream in the transport direction of the paper of the platen roller 1 are two pen wheels 10 which are rigidly connected to one another via a square axis 11.
  • the pin wheels engage with their pins in the side perforation of the continuous paper.
  • On one side of these pin wheels is connected to the square axis 11 which is shown in FIG. 2 posed locking direction arranged arranged with a ratchet wheel 12 into which a pawl 13 engages via a locking projection 13/1.
  • the pin wheels 10 are mounted with their square axis in the frame 14 of the printer.
  • flanks 27 of the toothing 26 of the ratchet wheel 12 and the locking projection 13/1 are so matched in terms of their pitch that a strong escapement is generated in the direction of rotation 28.
  • this inhibition resistance can be overcome from a certain force, and the pawl 13 swings out again.
  • the printer itself is covered by a paper discharge flap 15, the outer surface (surface) 16 of which serves as a guide surface for the continuous paper and which has on its inner surface guide lugs 17 which cooperate with the printer frame 14, so that a paper guide channel when folded (FIG. 1) 18 is formed for the continuous paper.
  • This paper guide channel 18 runs in such a way that the continuous paper with its edge perforations is guided over the pin wheels 10 so that a certain number of pins, e.g. three engage in the peripheral perforations.
  • These guide elements 19 can also be formed and attached to the paper discharge flaps.
  • an electro-optical scanning device 20 Arranged in the area of the platen roller 1 is an electro-optical scanning device 20 which interacts with the actual control arrangement 21 of the printer, which is implemented in a known manner, namely via a comparison device 22.
  • the paper discharge flap 15 corresponding to the ge is used to insert the continuous paper dashed representation opened.
  • a projection 23 (FIG. 2) arranged on the paper guide flap 15 releases the pawl 13, which pivots about an axis of rotation 24 under the action of a spring 25 (arrow direction) and with its latching projection 13/1 into the toothing 26 of the ratchet wheel 12 engages.
  • the pin wheels 10 can also be rotated backwards after overcoming the inhibition resistance, which enables the paper to be inserted and pretensioned precisely.
  • the inhibition resistance must be chosen so large by appropriate dimensioning of the spring 25 in connection with the flanks that even heavier paper from e.g. 90g / cm2 is held by the locking mechanism without it sliding out of the paper guide due to its own weight.
  • the optoelectronic device detects the holes in the edge perforation of the continuous paper and compares the feed measured in this way with the nominal feed in the form of electrical signals which are taken from the stepper motor 2. Depending on the comparison process, the control arrangement 21 and thus the feed and the position of the continuous paper is then corrected via the comparison device 22.
  • the paper discharge flap 15 is first opened and the locking mechanism is thus engaged. Since the locking mechanism is designed as a locking mechanism that emphasizes the direction of rotation, the paper can be pulled backwards without having to pivot the guide elements after overcoming the locking inhibition force. This is possible either by pulling the continuous paper 4, or by turning the handwheel. After the inlet channel has been released, the paper discharge flap 15 is closed again and the individual sheets 3 can be fed individually to the paper feed channel 6 of the platen roller via the paper guide channel 9 for single sheets or with the aid of an automatic feeder.
