Definitions

  • the invention relates to a paper feed device according to the preamble of patent claim 1.
  • Paper feed devices of the type mentioned at the outset are generally known and have been used successfully
  • a device for feeding paper sheets for a writing office machine which has a paper supply area, which consists of a rectangular trough-shaped housing, and has a base plate and side walls.
  • guide walls are inserted into the cassette, which lie against the side of the paper stack.
  • a pressure plate is pivotably articulated in the vicinity of the base plate. The pressure plate rests on the back of a stack of paper and is pressed into the open housing plate by a compression spring which is inserted between the bottom plate and the bottom plate at the freely pivotable end of the pressure plate.
  • a compression spring which is inserted between the bottom plate and the bottom plate at the freely pivotable end of the pressure plate.
  • a separating roller which is driven by a motor, is provided in the swivel range of the pressure plate to pull off the individual sheets from the paper stack.
  • the cassette To refill paper, the cassette must be removed from the printing device and reinserted after loading the paper. Single sheets can also only be inserted into the printing device after the cassette has been removed.
  • the invention is based on the object of designing a paper feed device of the type mentioned in the introduction in a simple and user-friendly manner.
  • the lever by means of which the pressure plate is pivoted from the operating position into the loading position, the separating corner flaps being pivoted away in the latter, has the effect that the paper stack can be inserted into the storage area without further operator manipulations.
  • the pressure plate can advantageously be pivoted into the middle position, in which a single sheet can be fed directly to the writing area in a user-friendly manner. 1
  • displaceable pressure plate enables the storage area to be adapted to different paper widths.
  • bracket is actuated via the axial attachment of the lever. 10
  • singling corner flaps are pivotally mounted on the pressure plates.
  • the singling corner flaps are pivoted away from the pressure plates in the loading position.
  • the slot provided in the base plate of the storage area makes it easy to insert small-format single-sheet paper.
  • FIG. 1 shows the paper feed device according to the invention in front view
  • FIGS 2-4 the paper feed device in side view 30 at different positions of a lever.
  • a paper feed device is removably arranged, which essentially consists of two pressure plates which are pivotally mounted on a stationary frame part
  • the pressure plate 1 is in this case mounted in a stationary manner, while the pressure plate 2 is slidably mounted along the singling roller 3, for example on an axis fastened between the side walls of a printer housing in the upper part of the pressure plates 1, 2.
  • the paper is moved, sheet by sheet, via the motor-driven separating roller 3, via a paper feed channel, to a writing or printing station with a platen roller 18 indicated in FIG. 4 and written there line by line using a writing head, not shown here.
  • a support surface 16 is provided which is firmly connected to the printer housing. A lies on this contact surface 16 Stack of paper 5 on. The support surface 16 extends so far in the direction of the separating roller 3 that the paper drawn off from the paper stack 5 can be moved freely downwards.
  • the pressure plates 1, 2 or the inserted paper stack 5 are pressed against the separating roller 3 by springs, which are not specified in any more detail.
  • the pressure plates 1, 2 are pivotably attached to the printer housing or to a removable frame part of the same.
  • the corner tabs 14 engage under the bearing surface 16.
  • the corner tabs 14 make this movement up to the predetermined central position of the pressure plates 1, 2 (see FIG. 2).
  • the corner flaps 14 will, or 'sheet-metal strip 15 to which they are attached, by a fixed to the printer casing stop 17 push plates 1,2 in the opposite direction from the An ⁇ pivoted away (see Figure 3) .
  • the paper stack 5 can be inserted into the paper supply area.
  • a U-shaped bracket 6 is provided for pivoting the pressure plates 1, 2, which is rotatably mounted in two bearing elements 7, 8.
  • the two bearing elements 7, 8 are arranged on the side of the pressure plates 1, 2 and are connected to the housing of the pressure device or to a removable part of the same.
  • a central leg 9 of the U-shaped bracket 6 is articulated behind the separating roller 3 in the lower region of the pressing plates 1, 2, so that when the bracket 6 is pivoted, the pressing plates 1, 2 can be pivoted away from the separating roller 3 are.
  • a rotatably mounted lever 10 is provided according to the invention, the axis of rotation of which is arranged parallel to the central leg 9 of the bracket 6 or to the pivot bearings 7, 8.
  • the lever 10 has on a lever arm 12 an axially aligned shoulder 11 which bears against a lateral leg 13 of the bracket 6. When the lever 10 rotates, the bracket 6 can thus be pivoted.
  • the central leg 9 of the bracket 6, which can be seen in its entire length in FIG. 1, is shown in a side view in FIGS. for example seen as a circle.
  • the approach 11 on the lever arm 12 of the lever 10, which is shown in its entire length in FIG. 1, can be seen in FIGS. 2-4 in the axial direction as a circle at the end of the lever arm 12.
  • the fulcrum of the lever 10 is in the
  • lever 10 can be locked in these three positions. These locking elements are not shown in the drawing.
  • FIG. 4 shows a paper storage area 20 arranged in front of the paper supply area.
  • the paper which is guided around and described around the platen roller 18, is transported into and deposited by depositing rollers 19 therein.
  • the paper storage area is delimited by a base plate 21, which is fastened between the side walls of the printer housing.
  • a slot 22 is provided in this base plate 21 which is parallel to the separating roller 3 and through which a small-format single-sheet paper can be fed to the platen roller 18. This path is shown in Fig. 4 by an arrow.
