    1487724 Keyboards with coded outputs; telegraphy SIEMENS AG 24 June 1976 [25 Sept 1975] 26228/76 Heading H4P [Also in Division G4] An arrangement for coding data characters comprises a counter TUZ arranged to count cyclically pulses of a pulse train G, a keyboard matric TMF comprising a plurality of intersection points, each associated with a respective data character key and a respective associated count of counter TUZ, for producing in response to actuation of each key one transfer pulse at a time when the counter has the count associated with that key, a gating circuit T1 arranged to transfer the count (e.g. to a store PS) in response to a transfer pulse supplied thereto, means UVFG for supplying the transfer pulse to T1 in the absence of an inhibiting signal, means SDC, T2, OVMZ for detecting a count associated with a hybrid data character key (e.g. õ, ÷, ³, shift) for the coding of which a plurality of consecutive coded characters are required and for producing the inhibiting signal in the presence of a transfer pulse, and means SZ, ASP, FWSP responsive to the production of both a transfer pulse and an inhibiting signal to produce and to supply to T1 a plurality of consecutive transfer pulses at times at which the counts of TUZ are those associated with keys relating to consecutive data characters (e.g. a, e) corresponding to the hybrid data character (e.g. õ) selected. As shown, SDC detects a hybrid count to produce a signal on one of four leads which passes through a gate T2 enabled by the transfer pulse to a gate OVHZ and an addressing store ASP (Fig. 3, not shown). The output of OVMZ provides the inhibiting pulse for a gate UVFG, and also enables a counter SZ which counts pulses G in synchronism with TUZ. The outputs of ASP and SZ address a read-only store FWSP (Fig. 3) which produces one output from each of a pair of selected NOR gates therein at counts in SZ corresponding to the required two characters making up the hybrid. These outputs pass via gate OVFG to enable gate T1 for the corresponding counts in TUZ. A counter ZZ, a gate NOR32 and an analyser TB are provided to eliminate "bounce effects". Circuit SDC may be neutralized by an input A (e.g. from a keyboard key so that no hybrid characters, or only certain ones, are detected.

    (54) DEVICE FOR INPUT OF INFORMATION
    one
    The invention relates to the field of computer technology.
    A device for interfacing is known comprising a converter of the intended value into a digital code, a controller of five AND elements, an OR element, a trigger, two signal conditioners, a switch, a strobe pulse generator, two groups of AND elements, and a group of OR elements
    The closest to the technical essence of the invention is a device for inputting information containing a matrix of switching elements, the horizontal buses of which are connected to the outputs of the first decoder, the vertical buses with one multiplexer outputs, the inputs of which are connected to the corresponding outputs of the ring counter, the inputs of which are connected to the outputs of the pulse generator, and other outputs - with the inputs of the first decoder
    2 ..
    The disadvantage of these devices is owner. There is no possibility of separating mixed informational signs.
    The aim of the invention is to extend the functionality
    devices by separating messed informational signs.
    The goal is achieved by the fact that the proposed device
    5 contains two memory blocks, the AND element, the address register, the first element. OR, the first valve block connected in series the second decoder, the second valve block, the second
    10 OR element and a counter connected to the outputs of the pulse generator / the first and second inputs of the address register, one output of the first memory block, the first input of the AND element and
    15 The first inputs of the first memory block, the second inputs of which are connected to the outputs of the address register / other outputs - with one input of the first OR element, the other input of which
    20 is connected to the output of the element I, the output from the first input of the first blok of the valves, the second inputs of which are connected to the outputs of the ring counter and to the inputs of the second decoder, the outputs to the inputs of the second memory block. The multiplexer output is connected to another input of the second valve block and the second input of the electrical unit I, and the third inputs of the register of address 30 with the outputs of the second valve block.
    The block diagram of the device is shown in the drawing.
    The device contains a pulse generator 1, a ring counter 2 / second decoder 3, the second valve block 4, the second element OR 5 / counter 6, the first decoder 7, the address register 8 / first memory block 9 / multiplexer 10 / element 11, the first element OR 12 / the first block of valves 13 / the second block of memory 14 and the matrix of switching elements 15. The device operates as follows.
    From the output of the pulse generator 1, the counting pulses and recording pulses are fed to the inputs of counter 2 / address 8 and counter 6. The output of counter 2 generates a code / which, via decoder 7 together with multiplexer 10, polls the switching elements of matrix 15. As a result, the last at the moment of coincidence of the code from the output of the counter 2 and the associated switching element of the matrix 15 corresponding to it, a readiness to write signal (which is fed to the inputs of the valve block 4 and AND II) is generated. If the decoder 3 detects the presence of a code / representing the usual data (not mixed information signs) when the readiness signal is received at the valve block 4, element 11 is opened. At the same time, the first output valve block 13 / recorded the code with. the output of counter 2 in the memory block 14.
    If there is a code / corresponding to the mixed information signs, at the output of the decoder 3, the permitting level (which) arrives at the input of the gates 4 at the same time as the readiness signal from the multiplexer 10 output / opens the gates. At the same time, at the output of these gates, signals are generated that enter the input of the address register 8 and through the OR element 5 to the counter 6 and the element 11. When a signal arrives at the input of the element 11, it blocks it. In this case, from the output of the memory unit 9, recording signals are output through the element IL12 to the input unit of the valve unit 13 at the moments when the output of the counter 2 forms codes / corresponding to separate information signs, through which mixed information signs are formed. determined by the applicable code.
    Thus, / in the device, the separation of mixed information characters is achieved when the latter are entered from the matrix of switching elements.
