Definitions

  • the invention relates to a paper guide device for office machines, in particular for matrix printers, consisting of a mounting part located above the writing abutment, which has a paper feed shaft and in the area of the writing abutment, angular trays for single sheets.
  • a paper guide device is known (DE-PS 28 56 950), which forms a paper guide shaft together with the rear wall of a storage compartment.
  • the single sheets described are conveyed tangentially to the writing abutment in the storage compartment.
  • the individual sheets are stacked on top of each other according to their consecutive numbers (1,2,3,4, ...) so that the highest number is always on top.
  • This disadvantage must be compensated for by rearranging from bottom to top.
  • Such a re-sorting may still seem feasible if there are fewer than five single sheets. In the long run, however, such sorting is time-consuming and therefore expensive and cumbersome.
  • the invention is therefore based on the object of carrying out the stacking process optionally for numbered single sheets in the order of increasing numbers, so that the finished paper stack is in the correct order of the increasing number sequence 1 to X and no longer has to be sorted.
  • a second storage compartment can be provided for pages that are not to be numbered.
  • the object is achieved in that in the area of the writing abutment a front, pivotable about a horizontal axis storage compartment and a rear storage compartment are provided in that an adjustable paper guide is arranged between the storage compartments is, with the pivoting movement of the pivotable storage compartment an adjustment of the paper guide in the direction of the front storage compartment or the rear storage compartment is connected. It is therefore sufficient to switch the front storage compartment from a basic position to a working position for switching on the stacking with increasing number sequence 1 to X.
  • the individual sheets are immediately stacked one after the other, with the first single sheet of the sheet stack with the number 1 lying on top.
  • the paper guide be formed from at least one pair of shafts arranged between the storage compartments with drivable friction rollers and at least one switch tongue arranged between the pair of friction rollers and the abutment.
  • the pivoting of the front storage compartment is therefore used to bring the paper guide into the desired position.
  • front, pivotable, angular storage compartment being adjustable from the storage position into a position which is flush with the attachment part on its end face.
  • the front storage compartment thus provides extremely ergonomic access to the individual sheets of a stack of sheets in the correct sequence of numbers.
  • the front storage compartment advantageously fits into the outer design of the attachment part.
  • the front storage compartment is mounted on the side walls of the attachment part about the horizontal pivot axis, and also has guide curves in pairs, in each of which a bearing plate is guided, two bearing plates receiving the pair of shafts with the friction rollers and the switch tongue between them and the bearing plates are each pivotally mounted about a common horizontal axis in the side walls of the attachment part.
  • a leg spring abuts against the outer circumference of the shafts and that one of the shafts is mounted in an elongated hole which runs in the direction of the adjustment path for different paper thicknesses between the two friction rollers.
  • bearing plates each have a locking projection and that latching means are provided in the side walls of the attachment part for the operating position of the pivotable front storage compartment and for its non-operating position.
  • the paper guidance in the respective storage compartment is further improved in that resilient guide fingers are attached to the switch tongue, which are angled in the area of the shafts in each case towards the direction of the front storage compartment or towards the direction of the rear storage compartment.
  • a mounting part 1 is shown with solid lines (FIG. 1), while a matrix printer 2, for which the mounting part 1 is used, is shown with dash-dotted lines.
  • the paper guide device described below is located within the attachment part 1 and is arranged between the side walls 3a and 3B of the attachment part 1. As can be seen, the attachment part 1 is attached in the area of the writing abutment 4. On the rear side 5 there is a paper guide shaft 6, through which single sheets 7 are fed to the abutment 4, printed on the front side and then deposited in angular trays in a stack of sheets.
  • a front storage compartment 10 which can be pivoted about a horizontal axis 9.
  • a horizontal axis 9 is rotatably supported in the side walls 3a and 3b of the attachment part 1 .
  • a rear storage compartment 11 is part of the attachment part 1.
  • drive gear trains which will be described in more detail.
  • a paper guide 12 is formed in connection with these drive gear trains, which can be aligned in two positions directed towards the storage compartments 10 or 11, in which the single sheets 7 are driven into the storage compartments 10 or 11.
  • the drive energy is transmitted via a pair of shafts 13a and 13b with drivable friction rollers 14a and 14b and the direction is determined partly by the pair of friction rollers 14a and 14b and partly by a switch tongue 15.
  • the drive of the friction rollers 14a and 14b is achieved via the drive gear train mentioned, which starts from a gear 16 on the platen 4, a platen, and drives intermediate gears 17, 18 and 19 to a gear 20 which is assigned to one of the friction rollers 14a or 14b is.
  • the friction roller 14b which is rigidly rotatably mounted, is provided with the toothed wheel 20.
  • the front storage compartment 10 is mounted with the horizontal pivot axes 9 in the side walls 3a and 3b of the attachment part 1 and is flush with the end face 1a of the attachment part 1 in the inoperative position (FIG. 3).
  • 10 guide curves 21 are provided in the side walls 10a and 10b of the storage compartment, in each of which a bearing plate 22 engages with guide pins 23.
  • the two bearing plates 22 opposite each other across the width of the attachment part 1 receive the shafts 13a and 13b with the friction rollers 14a and 14b between them, and the switch tongue 15, which extends over the full width between the two bearing plates 22 in the form of a rod.
  • the two bearing plates 22 are pivotally mounted as an assembly about the common horizontal axis 24 in the side walls 3a and 3b of the suspension part 1.
  • the bearing plates 22 carry the friction rollers 14a, 14b as well as the switch tongue 15 and the guide pin 23 mentioned in each case.
  • An elongated hole 25 is also provided for the shaft 13a, which permits a movement of the thickness of the associated friction roller 14a by different thicknesses of individual sheets 7 feed.
  • the two shafts 13a and 13b are pressed together by a leg spring 26, which is highlighted by a double dash line. The legs 26a and 26b each rest against the outer circumference 27 of the two shafts 13a and 13b.
  • the bearing plates 22 also each have a locking projection 28 on.
  • two locking pins are fastened as locking means 30 in the attachment part 1 at a radius from the axis 24 on which the switch tongue 15 is mounted and which at the same time forms the axis of rotation for the intermediate wheel 19.
  • switch tongue 15 Since the switch tongue 15 is fixed on the axis 24, the switch tongue 15 always moves with the intermediate wheel 19.
  • resilient guide fingers 31 and 32 are fastened on both sides, each in the area of the shaft 13b or the friction roller 14a for direction of the rear storage compartment 11 toward the direction of the front storage compartment 10 are angled to form a fixed path for each individual sheet 7 depending on the paper guide into the two storage compartments 10 and 11.
  • the storage compartments 10 and 11 are provided with a paper support 33 which can be interchangeably attached to them. After removal of the paper support 33 from the front storage compartment 10 and swiveling in, the paper guiding devices are largely form-closed.
