Definitions

  • the invention relates to a typewriter or similar office machine with a disk-shaped type carrier and a device for preventing the ribbon from getting caught with a disk-shaped type carrier of the type specified in the preamble of claim 1.
  • In typewriters it is known to lift the ink ribbon only for the type print in the area of the line to be labeled, so that, as long as no type print is carried out, the set line of the paper to be labeled remains freely visible to the person operating the machine.
  • the line judge and the center marking are also arranged in the above-mentioned space. This also narrows the gap further.
  • the object of the invention is to design the individual parts of the machine that are absolutely necessary for writing in the area of the imprint location in such a way that no malfunctions occur in the type imprint or in the correction process. This object is achieved by the invention specified in claim 1.
  • the machine according to the invention prevents in the simplest way that the disk-shaped type carrier can get caught with the ink ribbon or other individual parts of the machine present at the impression point.
  • the protective strip according to the invention also guides the ink ribbon in the area of the impression point and also serves as a line judge. As a result, the number of individual parts present in the area of the impression point is reduced compared to other known arrangements.
  • the protective strip can be arranged and locked with simple means. Due to the advantageous embodiment of the subject matter of claim 7, the subject matter of the invention becomes cheap and enables easy assembly. The further advantageous refinements of the subject matter of the invention according to claims 9 and 12 enable use even with machines with a switchable step division.
  • FIG. 1 shows a carriage 3 which can be moved along the recording medium 1 by means not shown, with a disc-shaped type carrier 5 which is adjustably mounted thereon.
  • the record carrier 1 can be transported by means of the platen roller 7, which can be driven in a known manner by means not shown.
  • the disk-shaped type carrier 5 has on its circumference radially extending type arms 9, at the ends of which the type elements 11 are arranged.
  • the type elements 11 are brought in front of the impression point 13 by control means which are operatively connected to the disc-shaped type carrier, the type elements being brought to the impression on the recording medium 1 by means of a not shown hammer using an ink ribbon 15.
  • the ribbon 15 is one Unwrapped supply spool 19, which is rotatably mounted in a cassette 17 which is exchangeably arranged on the carriage 3, and passes through a slot in this cassette 17 to 2 ribbon guide forks 21, 23 arranged at a distance from one another.
  • This ribbon guide forks 21, 23 guide the ribbon 15 in the region of Impression point parallel to the plane of the recording medium 1.
  • the ink ribbon 15 After leaving the ribbon guide forks 21, 23, the ink ribbon 15 passes through an entry slot back into the ink ribbon cassette 17 to a take-up reel 25, which winds up the ink ribbon 15 in a known manner by means not shown.
  • the ribbon guide forks 21, 23 are slidably arranged in guides 27, 29 firmly connected to the slide 3 in order to lift the ribbon into the printing position according to FIG.
  • the ribbon guide) 21, 23 are lowered again with the ribbon 15 so that the person operating the machine can see the writing line.
  • the guides 27, 29 for the ribbon fork 21, 23 arranged on both sides of the disc-shaped type carrier have inwardly directed bearing arms 31, 33, between which a thin protective strip 35 below the print line between the disc-shaped type carrier 5 and the part of the ribbon 15 guided parallel to the writing plane is arranged taut.
  • Eccentric bolts 37, 39 are frictionally connected to this protective strip 35 on both sides, their eccentrics 38, 40 in bearing bores 41, 43 of the protective strip 35 and their bolts 45, 47 arranged in the writing direction, elongated holes 49, 51 of the bearing arms 31, 33 being displaceable and lockable by screwdrivers 53, 55 are stored.
  • the protective strip 35 which is provided on its upper edge 57 with line markings 59 and with a center marking 61, can be aligned precisely with the lines.
  • the line markings 59 and the center marking 61 are formed in one piece with the protective strip 35.
  • the character markings 59 consist of projections 62 with edges 63 located on a common straight line. In order that the subject of the invention can also be used in machines with a step division switching device, the projections 62 are each spaced by half an inch. This applies in particular to division switching devices with 10 characters or 12 characters per inch.
  • the protective strip 35 has a U-shaped recess 65 which is open toward its upper edge 57 and for the passage of the type arms 9 of the disk-shaped type carrier 5 which are to be moved for printing.
  • the center marking 61 is arranged in the center above the U-shaped recess 65 on a web which runs parallel to the common straight line of the projections 62 and which is firmly connected to the upper edge 57 of the protective strip 35 via two lateral alignment webs 69, 71.
  • the lateral alignment webs 69, 71 are spaced one inch apart by a full character width and are so narrow that the alignment webs 69, 71 are always between two adjacent letters. Since this does not cover any letters, the legibility of the printed lines is always guaranteed.
  • the upper web 67 is also so far from the edges 59 of the projections 62 and so narrow that its width is smaller than the smallest distance between two lines. The web 67 is always in the free space between two successive lines when writing.
  • the protective strip 35 also has a continuous leading edge 73 below the lower longitudinal edge of the ink ribbon 15, through which the radially extending type arms 9, which are not yet in their starting position, can be pressed from the region of the ink ribbon level with types 11 arranged at their ends.
  • the leading edge 73 is bent somewhat from the recording medium 1 and projects with its free end under the lower longitudinal edge of the ink ribbon 15. The protective strip 35 thus prevents the ink ribbon 15 from getting caught with the circumferential disk-shaped type carrier 5 even when the type arms 9 of the disk-shaped type carrier 5 have not yet been returned to their starting position.
  • the protective strip 35 it is also possible for the protective strip 35 to be arranged in a resilient manner between the guide parts 27, 29 for lifting and lowering the ribbon forks 21, 23.
  • the protective strip has a shoulder bolt 75 on both ends, which can be locked by means of a locking recess 77 on a spring-shaped arm and an edge 81 on the guides 27 and 29, see FIG. 4.
  • the two longitudinal edges 83, 85 of the U-shaped recess 65 of the protective strip 35 are rounded on the inlet side for the resilient type arms 9 of the disc-shaped type carrier 5.
  • the bolts 45, 47 of the eccentric bolts 37, 39 provided with a slot for adjustment are fixed according to FIG. 1 by means of the nuts 53, 55. This fixing can also take place in that the bolts 45, 47 are provided with an internal thread 42 into which screws according to FIG. 2 can be screwed.
