Изобретение относитс к вычислительной технике и может использоватьс в печатающих устройствах.The invention relates to computing and can be used in printing devices.

Известно устройство дл поэлементной записи символов, содержащее разр дные цепи по числу знаков в строке записи, кажда из которых состоит из соединенных последовательно входного регистра и дешифратора кодов символов, блок вертикального поэлементного разложени символов и разр дные группы входных формирователей, подключенные своими выходами к шинам.A device for recording element-by-element characters is known, which contains bit circuits by the number of characters in a recording line, each of which consists of serially connected input registers and a decoder of character codes, a block of vertical element-by-decomposition of symbols and bit groups of input drivers connected to the buses by their outputs.

Однако известное устройство имеет сложную конструкцию и невысокую надежность работы.However, the known device has a complex structure and low reliability.

Цель изобретени - сократить оборудование и повысить надежность работы устройства .The purpose of the invention is to reduce the equipment and increase the reliability of the device.

Это достигаетс тем, что предлагаемое устройство содержит преобразователь, блок горизонтального разложени символов, разр дные элементы ИЛИ, группы разр дныThis is achieved by the fact that the proposed device contains a converter, a block of horizontal decomposition of symbols, bit elements OR, bit groups

и выходных элементов И, причем входы разр дных элементов И соединены с одноHMeHHbpviH выходами кодового преобразовател и дешифраторов кодов символов раз р диых цепей, выходы этих элементов чере разр дный элемент ИЛИ подключены к первым входам групп выходных элементов И, вторые входы которых включены к соответствующим выходам блока горизонтального разложени символов, а выходы - к выходным формировател м, и входы кодового преобразовател соединены с выходами блоков вертикального и горизонтального разложени символов.and output elements AND, and the inputs of the bit elements AND are connected to one HMeHHbpviH outputs of the code converter and decoders of the character codes of the various circuits, the outputs of these elements are alternating the bit element OR, the second inputs of which are connected to the corresponding outputs the horizontal decomposition block of the symbols, and the outputs to the output formers, and the inputs of the code converter are connected to the outputs of the blocks of the vertical and horizontal decomposition of the symbols.

На чертеже изображена функциональна схема устройства. .The drawing shows a functional diagram of the device. .

Дл нагл дности символы (знаки) на чертеже разложены на шесть строк и четыре столбца, а набор различных печатных знаков содер.жит только цифровые обозначеНИИ .For the sake of clarity, the symbols (characters) in the drawing are laid out in six lines and four columns, and the set of different characters in characters contains only numerical designations.

Каждый из выходов (ко/п1чество которых равно числу различных печатных знаков ) блока кодового преобразовани 1 .подключены ко входам групп одноименных разр дных элементов И 2.Each of the outputs (the quality / quantity of which is equal to the number of different printed characters) of the code conversion block 1 is connected to the inputs of the groups of the same name bit elements I 2.

Claims

The number of groups is equal to the number of bit chains, and the number of bit elements AND 2 in each group is equal to the number of different printed characters. Other inputs of the bit elements AND 2 are connected to the corresponding outputs of the codes corresponding to these groups of the decoders, 3, on the inputs of which they are connected to the histories of the 4 character codes by the number of bit circuits. The outputs of the group of bit elements AND 2 are connected through the bit elements of OR 5 to the common pairs of the corresponding groups of output elements of AND 6, the other inputs of the same output elements of AND 6 of the groups are connected to the corresponding outputs of the horizontal decomposition block of symbols 7 connected to the first inputs of the code conversion unit 1, the number of which is equal to the number of columns of the decomposition of the sign, and the other inputs of the block of the code converter 1, the number of which is equal to the number of rows of the decomposition of the sign, are connected to the outputs of the vertical block total number of groups of output elements And 6 is equal to the number of bits, and the number of elements in each group is equal to the number of columns of the decomposition of the sign: the outputs of these elements And 6 are connected to the inputs of the corresponding output drivers 9, the outputs of which, in turn connected to the recording elements. The device works as follows With the arrival of information on the registers. character codes 4 and simultaneously with the appearance at the outputs of blocks 8 and 7 of a pulse sequence, where the pulse transition frequency at the outputs of the vertical character decomposition block corresponds to the time of the information carrier per elementary step (one character decomposition line), and the pulse transition frequency at the outputs the horizontal decomposition block of the symbols corresponds to the clock frequency of the device, the outputs of the block of code conversion 1 appear characters converted during time-pulse codes Each point of any character, which is determined by the row and column numbers, corresponds to its own pulse in the converted time-pulse code, which, in turn, is determined respectively by the time of registration of this row and the number of the th-mta device in this row. With the help of the coincidence of the signals at the inputs of the bit elements AND 2, out of all the transformed moves, in each group one code is selected corresponding to the information recorded in the register. This time, the pulse code is fed to the inputs of output elements And 6, where decomposition occurs; These pulses are arranged in columns using pulses at the outputs of the block of horizontal decomposition of characters 7. Rows are decomposed automatically as the data carrier moves. Later, these pulses trigger the output shapers of which the outputs / writing pulses of certain parameters are triggered. , in turn, cause drawing points on the information carrier, and the totality of these points gives the configuration of symbols. Thus, in parallel recording of decomposition elements 1} of replacing the number of a mosaic memory of a configuration of symbols in the proposed device, one block of a code converter is used, which determines the economic efficiency of this device. An apparatus for writing element-wise characters, containing bit circuits by the number of characters in a recording line, each of which consists of serially connected input registers and a decoder of character codes, a block of vertical element-wise decomposition of symbols and bit groups of input drivers connected to the buses by their outputs records, which is valid so that, in order to increase the reliability of operation and simplify the device, it contains a code converter, a horizontal decomposition block, a symbol o, bit elements OR, groups of bit and output elements, AND, with the inputs of bit elements AND connected to the same outputs of the code converter and. 1difiers of character codes of bit circuits, the outputs of these elements through the bit elements OR are connected to the first inputs of groups of output elements AND, the second inputs of which are connected to the corresponding outputs of the block of horizontal decomposition of characters, and the inputs of the code converter connected to the outputs of the vertical and horizontal decomposition blocks of symbols.
