The invention relates to the combination of a copier with a copy-capable screen controlled by a computer, so that the copier is able to output graphics and text created by a commercially available computer.

The printer, as one of the ^most important devices* in the computer peripherals, can thus be replaced or at least partially replaced.
A variety of printer types with different technologies are known: for example, daisy wheel printers, matrix printers, thermal printers, inkjet printers and laser printers. The goals of all printer manufacturers for their products are, for example, speed, graphic capability, quiet operation, good typeface, the ability to make carbon copies and a long service life of the devices.

However, practice shows that even if these goals are only achieved at great expense, an extreme level of technology and cost is required if speed is to be achieved.
For example, matrix printers with three adjacent -

S0 lying print heads are known which can print up to 300 characters per second at simultaneous use and at a high noise level.

Low-noise inkjet printers print up to 600 characters per second. However, unlike all non-contact printers, they cannot produce throughput. With average font quality, the devices are very difficult to maintain.

Laser printers with perfect typeface and maximum speed (approx. 14 DIN A4 pages per minute) are very expensive and also require a lot of maintenance. Color prints cannot be produced.

The aim of the invention is to create a system that combines as many positive properties as possible from all known devices, but is primarily characterized by low noise and extreme speed, so that the question of the possibility of creating breakthroughs becomes irrelevant.

This object is achieved according to the invention according to claim 1 in that a device combination is formed from a copier and a computer-controlled, copyable display unit. By arranging the display unit in a suitable manner, either the display unit or a standard copy template can be copied. Further advantageous embodiments can be found in claims 5 to 7.

Well-known controllable display units, monitors or displays are, for example, cathode ray screens, plasma screens and flux crystal LCDs.

Preferably, liquid crystal displays are used, which are particularly suitable due to their flat construction and good copying ability. 20

According to the invention, the display unit can be arranged on the copier so that it:

- takes the position of a normal copy template. This also makes it possible to convert existing devices.

- installed at a suitable location inside the copier. A controlled mechanical adjustment of the scanning optics enables the display unit to be copied.

3Θ - the glass platen on which the copy templates are usually placed is replaced. LCD displays are transparent when not activated and thus enable conventional copying through the platen system.

In comparison to conventional printer designs as peripheral devices of computer systems, the combination device according to the invention offers advantages that cannot be surpassed by any other printer type&idigr;

- Maximum speed combined with low noise generation.

- By appropriate design and arrangement of the screen, the normal copying capability can be known copy templates are retained so that the combination device is both a printer and a copier. This results in a favorable price-performance ratio.

- Color copies can be made using color copiers and suitable color displays .

- Playback as enlargement or reduction is possible. independent of the computer software or hardware.
