Description

The invention relates to a teleprinter in which each character to be transmitted by a Group of dot pressure signal bits within a specified grid is represented with a number of symbol buttons which operate a number of symbol switches and with a diode matrix which has a plurality of conduction paths to these point print signal bits when closing the corresponding To generate symbol switches, this diode matrix having a number of inputs, connected to these symbol switches, and a number of outputs and with a commutator, which is connected to the matrix outputs.

From the German patent specification 956 767 a type image telex transmitter is known in which the symbol key 'five switches operated. In this known device Qiodengrup'pe'n are provided, which commutation segments with connecting lines, associate. With this well-known fine writing transmitter a considerable amount of circuitry is required to generate the type images.

The invention is based on the object of simplifying the circuit complexity for the teleprinter.

According to the invention, a single symbol switch is connected to the symbol buttons, and groups of Diodes connect commutator segments with connecting lines, and diodes are also provided, around each symbol switch with the required commutator segments and with the required To connect connecting lines.

In an advantageous manner, simple diodes are used to connect the connecting lines with simple Connect switches with two contacts that are operated by the buttons. This creates a great simplification achieved. ■

A number of common diodes can be located in a number of conduction paths with particular advantage. ■

With this design, the common diodes in the conduction path or in the Routes are used to have the same lines or lines of a letter or Symbols to be generated by the same diode circuit, so that the entire diode matrix is simplified can be. In particular, vertical lines of letters can be followed by the "same" Diode circuits are made.

In a particularly advantageous embodiment, the number of inputs of the diode matrix is greater than the number of outputs of the matrix, and they are output bit transfer devices and switching devices provided to control the operation of the commutator according to the actuation of any to activate the symbol selection switch, to carry out and · to terminate in order to achieve an over-; carry out a set of dot-print-signal bits, the number of these dot-print-signal bits is at least equal to the number of commutator inputs.

'Furthermore, it can be advantageous that at least one of the commutator segments corresponds to and represents a start section of the signal and that a number · of commutator segments a progressive sequence of dot / pressure signal bits of a represents a fixed grid, at least one of these segments being a stop portion of the character signal corresponds and wherein automatic start-stop devices are provided to the operation to control the commutator over a cycle, according to the actuation of each selection switch.
