Definitions
- the invention relates to an apparatus for the recording by the line of symbols on a sheet-like record carrier, utilizing an endless tape-like intermediate carrier upon which the symbols are recorded one after another at a single, locally fixed point, by a recording element, and subsequently applied, a line at a time, to the sheet-like record carrier by means of impression elements, forming parallel lines of printing.
- high speed printers are data-recording devices in which the recording of symbols of one or several lines is simultaneously performed, such as the simultaneous recording of symbols of the same kind of one line. Furthermore, when using chain printers, it is possible to simultaneously print several symbols in one line, dependent on whether the desired symbol merely stands in front of an impression point. It is common to all such apparatus that in line direction, one impression element is set up per impression point so that the symbols of a line may at least theoretically be recorded simultaneously.
- Purely mechanical high speed printing processes are characterized in that a type cylinder, type chain or one or several similar type carriers is conducted past the record carrier to be printed upon, and that impression elements which consist of a constructional unit or of individual elements are disposed in line direction. When the correct symbol passes by the impression point, the impression elements either strike the type carrier, moving it into engagement with the record carrier, or vice versa, whereby the record carrier is moved into engagement with the type carrier.
- Combinations of mechanical and non-mechanical printing processes are employed to enable the use of normal Writing paper for the recording of the information symbols.
- the symbols are recorded in non-mechanical manner on an intermediate carrier which consists of a special paper.
- the symbol recorded in this manner is colored with printing dye, such printing dye, which presents the outlines of the symbols to be printed, then being mechanically applied to the record carrier by means of printing elements.
- Such feature implies that after the information symbol, idle symbols have to be conducted to the recording element so that the total of the information symbols and the idle symbols corresponds to the normal of symbols which can appear on one line of the sheet-like record carrier. Since these idle symbols also have to be produced during the production of the information, an increased transfer time, and simultaneously, also an increased recording time is required because of this feature. Furthermore this recording process has the disadvantage that normally the information is not at hand in a manner suitable for high speed printers in which a printing of the symbols, by the line, is effected.
- the information exists in a form suitable for utilization in normal sheet printing machines in which, following receipt of the last information symbol, the carriage return and the line advancing immediately takes place.
- the transfer time is also restricted to a minimum.
- the problem is solved by an apparatus which is characterized in that in a line direction of the sheet-like record carrier, a number of individual printing hammers, printing the color symbols by the line and in parallel relation, from the intermediate carrier upon the record carrier, and in which said hammers can be operated independently of each other in dependence upon the number of symbol positions registered in the particular line to be printed.
- a counting device is operable to count the symbols of the particular line, enabling the symbols of the next line to immediately operatively follow the last symbol of the preceding line.
- This process has the advantage that only one recording element is required for a single symbol position. Because of the recording of the individual signs one after another an electronic storage installation is not necessary as the symbols may be applied to the intermediate carrier in series as they are delivered from the data processing apparatus. In spite of this, the symbols can be printed on the record carrier by the line. This is advantageous since in the case where the symbols have to be printed mechanically, one after another, the mechanical printing elements are not suitable for high speeds which would occur in this case. However, if the recording of the symbols is done by the line, a correspondingly higher interval of time during which the printing elements can move to and from the printing point is available for the individual symbol impression. In comparison therewith, the impression time is extremely short.
- the expenditure in comparison with known line printing apparatus is not increased, but rather additionally reduced.
- a counting device which counts the number of symbols per line, recorded by the recording element upon the intermediate carrier is provided.
- the following symbols be stored by a storage device for a sufficient time to permit the intermediate carrier to be transported by so many symbol intervals that the information symbols intended for the particular line have been supplemented by idle symbols .so that the entire line width of the sheet-like record carrier is filled.
- such a storage device is not necessary. Only that amount of space actually corresponding to the symbol to be recorded on the sheet-like record carrier is required per line on the intermediate carrier.
- the width of the individual printing hammers, arranged side by side is equal to the width of the number of symbols to be printed which corresponds to the number of symbols required between two lines, received in series with the symbols to be printed, initiating the transfer to the next line.
- the transfer code group or the symbols initiating the transfer to the next line are WR WR Z1. Consequently the width of the individual printing hammers, arranged side by side, is equal to the width of three symbols to be recorded. Because of this feature, the symbol counting device may be simplified and the number of printing hammers set up in line direction may be reduced to one-third. By this selection of the printing hammers, it is assumed that at the end of the line an interval of at least one symbol width will exist between the last operated printing hammer and the next symbol intended for the next line.
- the individual symbols to be recorded on the sheet-like record carrier are recorded on the intermediate carrier by suitable recording elements, arranged transversely to the advance Slift of the intermediate carrier, in a point raster, for forming a point screen across the intermediate carrier.
- the recording of symbols by means of raster points results in the advantage that the same recording elements may be used in like manner for all of the occurring symbols. By means of raster points, symbols can also be reproduced which normally are not included in the usual customary symbol groups.
- the recording elements disposed transversely to the advance direction of the intermediate carrier are offset in relation to each other. Because of this feature, no reciprocal influencing occurs between recording elements lying in side by side relation.
- ink dispensing elements reproduce the shape of the symbols to be printed one after another onto an intermediate carrier, following which the ink symbols are printed on the sheetlike record carrier, by the line, in a flying manner by mechanical means, for example, by individual printing hammers.
- FIG. 1 is a schematic view of a high speed printing installation, wherein a magnetic tape is utilized as an intermediate carrier;
- FIG. 2 is a schematic view of such high speed printing installation in the vicinity of a printing hammer, utilizing an auxiliary electrode;
- FIG. 3 is a schematic view, similar to FIG. 2, of the high speed printing installation in the range of a printing hammer, utilizing a moistener for the record carrier;
- FIG. 4 is a perspective view of such a high speed printing installation.
- An intermediate carrier 1 is provided with a magnetic layer, and carried by two rollers 2, 3 is advanced in the direction of the arrow past seven writing heads 4, located perpendicularly to the transport direction, side-by-side relation, at a fixed position on the path of the intermediate carrier 1 (as best illustrated in FIG. 4).
- the intermediate carrier then moves from the writing heads 4 through a powder chamber 5 which is filled with magnetic printing ink 6, between a sheet-like record carrier 7 and printing hammers 8 disposed opposite to such record carrier, over an erase head 9 and finally over a cleaning brush 10.
- One of the two rollers 2, 3 is driven with constant speed by a suitable motor 18.
- Disposed behind the sheet-like record carrier, opposite to the printing hammers 8, is an auxiliary electrode 11.
- the symbols delivered for example, from a data processing machine, are magnetized in a point raster onto the magnetic material of the intermediate carrier 1.
- the intermediate carrier arrives in the powder chamber 5, where the magnetic printing color or ink 6 (hereafter designated printing ink) in the chamber 5 adheres to the magnetic spots of the intermediate carrier 1. Accordingly, the symbols to be printed appear on the intermediate carrier 1 in the magnetic printing ink.
- the intermediate carrier with the printing ink representing the symbols to be printed arrives in front of the sheet-like record carrier 7.
- the intermediate carrier has advanced sufiiciently that all symbols which are supposed to be printed on the sheet-like record carrier 7 in a single line have arrived between the sheet-like record carrier and the printing hammers 8 disposed opposite thereto, the printing of all of such symbols, by means of the printing hammers 8 upon the sheet-like record carrier, is simultaneously effected in a flying manner.
- the printing is effected in this case by the actual striking of the printing hammers upon the intermediate carrier 1 and at such moment the printing ink is transferred to the sheet-like record carrier 7.
- the motion of the individual printing hammers 8 toward the record carrier takes considerably more time than the actual printing process and is initiated prior thereto.
- the intermediate carrier is conducted around the roll 2 to an erase head 9, at which the symbols recorded magnetically upon the intermediate carrier 1 are removed so that a new magnetizing of the intermediate carrier 1 by the Writing heads 4 can be effected.
- the intermediate carrier is cleaned of any remaining printing ink by means of a cleaning brush past which the intermediate carrier 1 is conducted.
- the auxiliary electrode 11 on the reverse side of the sheet-like record carrier 7, operable during the actual printing may consist of a permanent magnet, or of conductors connected to a voltage of approximately 6 kv. It retains the printing ink on the paper during the hammer impact either by magnetic or by electrostatic forces.
- the auxiliary electrode 11 may be omitted if the face of the paper to receive the printing ink is moistened with water prior to the printing, by means of a moistener 12, illustrated in FIG. 3, so that the printing ink is retained by adhesion.
- the line-byline advancement of the sheet-like record carrier 7, which is withdrawn from a paper stock roll 13 is effected after each printing operation by a caterpillar-type toothed belt 14.
- the time interval available therefor during which the intermediate carrier is advanced by the width of the record carrier, is sufficient for the advancement of the record carrier.
- the record carrier is conducted past a heat source 15 which is screened by an adjustable diaphragm 16.
- An apparatus for the recording, by-the-line, of symbols upon a sheet-like record carrier comprising an endless tape-like intermediate carrier, arranged for movement in a path of a line-direction across the face of the sheet-like record carrier involved; means at a fixed position in the path of the intermediate carrier for recording individual symbols, one at a time, on said intermediate carrier, to sequentially form a line of symbols thereon and providing spaces between successive lines which are representative of transfer code group, said transfer code group comprising at least one carriage return signal and a line feed signal, said symbols appearing on said intermediate carrier in the form of respective inked characters, with the symbols for the next line immediately following the symbols for the preceding line and separated therefrom by a space equal to the width of said transfer code group without regard to the length of such preceding line; and a plurality of individually operable printing elements arranged in line-direction in cooperable relation to said intermediate record carrier, each of said printing elements having a width equal to or less than said space between successive lines, and being operative to simultaneously transfer the inked symbols for an
