Definitions

  • the invention relates to a computer-controlled printing and drawing device for printing on all printable materials, as well as heat, electrical and pressure sensitive paper.
  • the present invention is intended to solve the printing and drawing problems which, to date, have not been overcome by typewriters, offset machines, embossing machines, stamps and rubbing letters, etc.
  • Typewriters, offset and embossing machines require precise guide mechanisms, which are usually large and expensive and are only suitable for printing on the formats intended for this (thin paper of a given size).
  • the stamp can only reproduce contours for which it is intended.
  • Rub-off letters can only be transferred individually to the printing document in their present form.
  • fonts of all kinds, characters and drawings of any length can be produced with high speed and precision.
  • the maximum character height is given by the width of the printer head. It can be used to print on curved, or because of the size not movable or difficult to access areas, books, index cards, labels, forms, etc.
  • the device according to the invention can be carried out by hand, but it can also be used in drawing, recording devices and robots for printing objects.
  • connection of the printer head with an electronic computing and storage unit also allows a quick and even automatic change of the text, such as. Date, time, numbers etc.
  • printing can be carried out directly on heat-, electro- or pressure-sensitive documents. You can print on non-sensitive documents by inserting a color carrier (for example a ribbon) between the printer head and the base or using a modern inkjet printer.
  • a color carrier for example a ribbon
  • FIG. 1 shows a block diagram of an embodiment of the computer-controlled printing and drawing device.
  • FIG. 2 shows an embodiment of a printer head for heat-sensitive paper.
  • FIG 3 shows an embodiment of the printer head for electro-sensitive paper or electro-sensitive ink carriers.
  • FIG. 4 shows an embodiment of the printer head with friction wheels as a displacement sensor.
  • FIG. 5 shows an embodiment of a printer head with ink carrier and pressure roller which is connected to a displacement sensor.
  • FIG. 6 shows an embodiment of an optical displacement sensor with a light guide.
  • the printer head 1 is connected to the control unit 2.
  • the control unit 2 supplies all the control signals and voltages necessary for the operation of the printer head 1.
  • the data and signals are stored, processed and fed to the control unit 2 via corresponding lines 8.
  • the data flow to Control unit 2 is controlled by displacement sensor 10. Only the data corresponding to the travel unit covered are released from the travel sensor 10 to the control unit 2 or to the printer head 1. These are converted into discrete dots by the printer head 1, which then represent a type or character image on the base 11.
  • the data input 4 can be a keyboard, a computer or any superordinate data storage. The data can be entered individually or in blocks via the corresponding lines 9 into the computer or memory 3, from where they are processed further in the manner described above.
  • the supply unit 5 which can be an accumulator, a battery or an external supply, supplies the energy necessary for the operation of the computer-controlled printing and drawing device.
  • the control unit 2 and the computing and storage unit 3 are tiny. They occupy a space of less than 1 cm2. They are manufactured as monolithically integrated semiconductors or in hybrid technology.
  • the data input or the keyboard 4 can be built directly into the device or can be connected to a higher-level computer or memory via a connection (not shown in the block diagram).
  • FIG. 2 shows a printer head 19 that can be used for heat-sensitive paper.
  • Electrical conductor tracks 16 and 17 are attached to the carrier 15, which can be made of glass, ceramic, aluminum or magnesium oxide.
  • Two conductor tracks 16 and 17 are connected to a micro-heating element 18.
  • the heating elements 18 form on the apex 20 of the printer head 19 a line which is in contact with the base 11 to be printed.
  • the heating elements that are heated leave small dots of color on the surface that form a lettering 12 or a drawing.
  • FIG. 3 shows a printer head 25 for electro-sensitive ink carriers 29. It consists of the contact fingers 26 which are firmly embedded in a carrier 27. Such printers can if appropriately designed, write directly on electro-sensitive substrates 11 or indirectly via an electrically conductive ink carrier 29. The contact fingers 26 are in intimate contact with the ink carrier 29. If a current pulse is supplied to the contact finger 26, the ink carrier heats up directly and exclusively under the contact point 28 by means of a constriction of the current, causing a layer of ink to melt, which connects to the base 11. The circuit of the contact finger 26 with the ink carrier 29 is closed via a contact, not shown in Figure 3.
  • FIG. 4 shows an embodiment of the printer head 1 with friction wheels 10 as a displacement sensor.
  • the discrete points which can represent the lettering 12 or a drawing in a row, must be transferred to the base 11 depending on the distance covered.
  • This path can be determined, for example, with a friction wheel 10 which is designed as a position sensor. If two friction wheels are firmly connected to one another by an axis, not shown in FIG. 4, the parallel guidance of the printer head 1 on the support 11 is made considerably easier.
  • the friction wheels 10 can be embedded in the printer head 1.
  • the lines 31 connect the printer head 1 to the control unit 2.
  • the ink carrier 29 which is designed as an ink ribbon, lies between the printer head 1, the base 11 and the pressure roller 35. This configuration is suitable for printing on band-shaped documents 11.
  • the pressure roller 35 is simultaneously connected to the displacement sensor 36, which essentially consists of current-carrying lamellae 37. If the pressure roller 35 rotates with the displacement sensor 36 because the band-shaped base 11 with ink carrier 29 is pulled through between the printer head 1 and the pressure roller 35, the current-carrying lamellae 37 come into contact with the contact tongue 38 in turn.
  • the number of impulses is a measure of the distance covered. The impulses control the data flow and the write speed depending on of the path covered.
  • the ink carrier 29 is wound in a coil-shaped magazine 39.
  • FIG. 1 An embodiment of an optical displacement sensor is shown in FIG.
  • the displacement sensor essentially consists of the light source 41, the transmission light guide 42, the reception light guide 43 and the receiver 44.
  • a dot 45 is printed on the outer side. If the printer head 1 is moved in the direction of the arrow on the support 11, the optical displacement sensor 47, after the printer head 1 has traveled the distance 46, detects the point 45 and gives the printer head 1 the command to reprint a point 45, etc. There are no moving parts in this variant.
  • the printer head 1 with the computing and storage unit 3, with a data input 4 and the feed unit 5 can be accommodated in a small plastic housing with recesses.
  • the printing and drawing device can also be loaded or operated via a connection to any computer or memory.
