Definitions

  • the invention relates to an arrangement for mosaic printing units for recording characters using a character generator in which the printable characters are stored in binary form as column and row-by-character elements and with a control unit connected to the character generator and controlling the feed of the print head.
  • the characters can either be printed at a fixed distance, which, however, gives a significantly poorer overall impression of the typeface compared to type printing, or in proportional font with a spacing between the characters that is adapted to the character width.
  • a special character generator is usually used to generate proportional font in mosaic printing devices, in which the print head executes a feed path corresponding to the character width, in which a combination is assigned to each individual character, which contains a statement about the character width. In order to be able to carry out the required different feed paths of the printing unit, this information must therefore be queried in a complex manner by the character generator and supplied to control electronics. Such a character generator for proportional font is therefore constructed much more complex than a character generator for generating characters with a fixed character spacing.
  • the object of the invention is therefore for mosaic printing devices such as e.g. Represent ink printing devices to provide a circuit arrangement that makes it possible to generate proportional font using a known simple character generator, which is only intended for the generation of characters with a constant time interval.
  • mosaic printing devices such as e.g. Represent ink printing devices to provide a circuit arrangement that makes it possible to generate proportional font using a known simple character generator, which is only intended for the generation of characters with a constant time interval.
  • This object is achieved according to the invention in an arrangement of the type mentioned at the outset in that a character known per se is used as the character generator Generator for generating characters with a fixed character spacing is arranged, in which each character, regardless of its actual width, is assigned a memory field of the same size and each column of this memory field corresponds to a feed step, and that an operating state for generating proportional font and an operating state for generating characters with a fixed character section spaced control unit is provided, which has an evaluation unit which is designed such that it performs feed steps for occupied columns on the one hand, depending on the column assignment of the memory fields, on the other hand, the sum of not in the operating state for generating proportional font assigns a space advance of predetermined width to occupied columns between two adjacent characters.
  • the invention is advantageously based on the consideration that all the characters of the customary known fonts are written together and that there is therefore no empty column of the basic grid within a character. It is therefore possible to control the movement of the print head directly via the split grid, with which a character generator, which is set up for printing characters with a constant spacing, can be used.
  • Such characters are generated with the help of a mosaic print head, which e.g. can be an ink mosaic printhead, and is driven by a character generator.
  • the characters are stored in matrix-like memory fields of the same size SF.
  • the memory fields consist of fourteen columns, numbered from 0 to 13 and a corresponding number of lines. Each matrix point corresponds to a possible imprint point in the SF character field. These memory fields are queried column by column when a character is called up, with each column (0 to 13) of a memory field being assigned a single feed step of the write head.
  • the invention is based on the principle of arranging a feed step for each column of the character matrix occupied by an impression bit and a feed step with a defined width of e.g. four individual steps ZZ.
  • a fixed constant space ZZ is achieved in that, on the one hand, feed steps are only carried out with occupied columns, which are then followed by a feed step ZZ of defined width if an unoccupied column is arranged after an occupied column.
  • the information to be recorded is supplied in binary coded form, for example from a keyboard T, a magnetic tape or punched tape device or via a line from a control unit containing a character generator ZG outside.
  • the control bits for the mosaic writing mechanism are formed with its writing carriage SW and added to it via an amplifier stage. This is done in detail by reading out the character information from the character generator ZG column by column using a column counter SZ.
  • An OR gate 0G linked to the outputs then delivers an output signal if the column is occupied with an information bit (print bit).
  • This information is stored in a memory element SG, which can be a monostable multivibrator, for example.
  • a subsequent AND gate UG then sends a trigger signal to a control unit VA which triggers a feed, which triggers a large feed ZZ on the typewriter drive SW if the column currently present on the OR gate OG is not occupied with an information bit, but the preceding line with an information bit was occupied. In this case there is a logic zero at the inverting input of the AND gate UG and a logic one at the non-inverting input.
  • the AND gate UG therefore supplies a signal triggering a feed ZZ.
  • the control unit VA controlling the typewriter can be blocked if characters with a constant character spacing are to be written (numbers, "). This blocking can take place automatically if a decoding device is provided, which for numbers or quotes is triggered.
  • control unit AE In addition to the arrangement shown in FIG. 3, other embodiments within the scope of the person skilled in the art, in particular of the control unit AE, are of course also possible, so that the invention is not restricted to this arrangement.
