Definitions

  • the invention relates to an office machine, e.g. on a printer, with a printing unit, a continuous paper transport via a tractor and with a single paper transport via drive rollers.
  • Such an office machine designed as a printing device has become known, for example, from DE-PS 32 08 111.
  • the individual paper transport takes place in a base part with a paper feed from the front and a paper discharge at the rear.
  • the printing unit and the continuous form transporter are pivotally connected to the base part, the continuous form transporter being additionally hingedly connected to the printing unit.
  • the paper path for the continuous forms runs from an inlet on the lower front via a tractor in the continuous form transporter to an outlet on the upper front of the continuous form transporter. The two paper paths are therefore completely separate.
  • the invention has for its object to improve an office machine of the type mentioned in such a way that it is possible to switch from one mode of operation to another without requiring any special conversion work for the provision of the various paper paths.
  • This object is achieved in that for the deflection of the two paper paths, which form a common path behind the printing unit, a switch which is rotatable in the housing is provided, that the switch can be coupled to a tractor drive by means of a two-armed rotary lever, and in that each has been carried out by a rotary movement Coupling or uncoupling of the tractor drive results in a simultaneous switchover of the switch.
  • Such a positive coupling between the switch on the one hand and the tractor on the other hand ensures that when the tractor drive is uncoupled, single paper transport is made possible via drive rollers and the individual papers are stored in a storage compartment by a corresponding position of the switch.
  • the continuous paper transport is started, whereby at the same time, through the switch that is then adjusted, the continuous papers are not fed out of the machine into the storage compartment, but through a special slot on the side of the switch opposite the storage compartment.
  • a reliable design results from the fact that in the embodiment of the invention the rotary lever has two lockable positions and that in a first lever position the tractor is driven for continuous paper transport and the switch is set to continuous paper storage and that the tractor drive is uncoupled in a second lever position is, the pairs of rolls are set for single paper transport and the switch is set on single sheet storage.
  • An easy-to-produce connection between the switch and the rotary lever advantageously results from the fact that one lever arm of the rotary lever is operatively connected to the free end of a tab which is fixedly coupled to an axis of rotation of the switch.
  • the fact that the tab engages with a pin protruding at a right angle into a fork-shaped recess formed at the end of the lever arm results in a particularly robust, failure-prone design.
  • the tractor drive is preferably actuated in that the other lever arm of the rotary lever carries a drive roller which is driven by a main drive of the office machine and which can be brought into or out of engagement with a drive wheel of the tractor when the rotary lever is rotated.
  • This type of engagement and disengagement of the tractor drive is simple in construction and not prone to failure.
  • the rotary lever can be actuated in various ways.
  • a preferred embodiment is that the two-armed rotary lever is adjustable via a motor-driven eccentric, which acts on one of the two lever arms. This is preferably done in that one of the lever arms has a recess into which the eccentric protrudes.
  • manual operation can also be advantageous, the two-armed rotary lever being provided with an additional hand lever.
  • the rotary lever can be adjusted by moving a printer carriage horizontally.
  • the printer has as its central component a printing unit 10 with a printing roller 11 mounted in the side walls of the housing.
  • 12 is a tractor for the transport of continuous paper, which is rotatably mounted in the housing walls via bolts 13 and can take two lockable end positions.
  • 14 with a pivotable pivot point 15 of the housing walls is designated, which enables or facilitates access to the tractor 12 when folded up.
  • the pivot part 14 carries a switch 17 which can be rotated at point 16, which is provided with a tear-off edge 18 and has a non-rotatably arranged tab 19 with a pin 20.
  • a two-armed rotary lever 22 which has a first lever arm 23 and a second lever arm 24, is also rotatably mounted in a pivot point 21.
  • the first lever arm 23 stands over a fork-shaped recess with the pin 20 Tab 19 in connection.
  • the second lever arm 24 carries a drive roller 25, which is driven by a main drive 26 together with a further drive roller 27, which is mounted in the pivot point 21, via a toothed belt 28.
  • the rotary lever 22 contains a recess 29 into which an eccentric 30 projects. With 31, 32 and 33 pairs of rollers are designated, each having drive rollers and pressure rollers.
  • the paper path for individual papers is shown at 34, which are fed into a channel 35 and stored in a storage compartment 36.
  • the rotary lever 22 Due to the position of the eccentric 30 shown in Figure 1, the rotary lever 22 is pivoted clockwise about the pivot point 21, so that the drive wheel 25 is disengaged from the drive wheel 12a of the tractor. This means that it cannot feed continuous paper.
  • the switch 17 Due to the aforementioned rotary movement of the rotary lever 22, the switch 17 is simultaneously moved to the right about the pivot point 16 via the fork-shaped end 23a of the lever arm 23, so that the individual papers pass the switch 36 into the compartment 36 on the left.
  • the eccentric 30 is rotated through its pivot point 30a by 180 ° and assumes the position shown in FIG.
  • the rotary lever 22 is moved counterclockwise and brings the drive roller 25 into engagement with the drive roller 12a of the tractor 12.
  • the switch 17 is moved to the left via the pin 20, so that now the path for the continuous paper transport past the switch 17 on the right leads and leaves the housing through a slot 37.
  • the paper path for the continuous paper in the operating position continuous paper transport is designated by 38 in FIG.
  • catch plates of a paper mill are designated, which form a common paper path for the individual papers and the continuous papers after passing through the printing unit 10.
  • the catch plates 39 are rotatably supported against the force of a spring 40 via a pivot point 41 on the pivot part 14.
  • the drive roller of the tractor 12 is shown in dashed lines when it is locked after rotation about point 13 in its second pivoted up position.
