Description

The invention relates to a recording-controlled typewriter as described in the preamble of claim I. specified genus.

From US-PS 30 63 536 a typewriter with a standard / eilenkontakt is known, which is for example ^{5 ()} in the column position 60 of the car. If a maximum of 70 characters are to be written in one line, words that have more than nine characters must be provided ^{with a hyphen v> at the hyphen when they are stored on the recording medium.} These »leading hyphens« are not taken into account in the main area of the line. When passing through a contact for the Standardzeilenlänj; e, however, a corresponding circuit is operated, so that automatically di pressing the spacebar; r ^b0 carriage return is triggered. In addition, the "prebincleslriclie" are now also taken into account, so that j: u long words are automatically separated into their syllables. The carriage return is then resolved.

So with this typewriter you have to look at the Words that are too long are stored on the recording medium, separated into their syllables by "leading hyphens" so that there is an automatic hyphenation after passing the corresponding contacts, the however, by a very cumbersome and inexpedient division of these long words when entering them must be bought.

Furthermore, from US-PS 22 97 789 a typewriter is known in which the location of the one provided, right edge area can change, which in the illustrated embodiment has a width of eight characters. SoI! with this typeface-ehine if necessary, automatic carriage return must be used, similar to the typewriter according to US-PS 30 63 536, reserved hyphens are used to automatically separate from to allow long words in syllables. So there is only one area with a variable position in one Automatic hyphenation can be carried out if the words are too long and appropriate hyphens have been coded.

The contact device provided in this typewriter is not one 7 dietary drills, but only about one Device that triggers the automatic hyphenation after passing the right margin stop if a Reservation hyphen occurs.

Finally, from DE-OS 15 61204 and the GB-PS 10 17 967 a record-controlled typewriter of the specified genus, in which the writing surface is divided into three areas. In the main area, the individual functions stored on the recording medium become more common Wise done, d. i.e., in this area the storage of a space bar also indicates actually the space between two characters.

When the car enters a fixed predetermined size / area, which is the case in the procedure according to DE-OS 15 61 204 is ten characters and for the typewriter according to GB-PS 10 17 967 is fifteen characters, when a certain function key occurs, for example the space bar, automarich the carriage return triggered, the carriage finally passes the right margin stop and enters the end area. What for example, it may be the case with words that have more contain as / chn or fifteen / oaks, the Car stopped automatically, and that word then has to be broken down into its syllables by hand. In this In this case, the hyphen key for the end of the syllable must be printed by hand, so that the Carriage return triggered by hand and this word can be reuergeschneben in the next line.

This fixed limit area in which the Carriage return is triggered automatically when certain characters appear, but is then inexpedient if the document contains a large number of long words. Then the car arrives namely relatively often in the end area in which the Control by means of the recording medium becomes ineffective and the control is now carried out by hand must become.

Another disadvantage of this known, recording-controlled typewriters is that in the end of a word that is too long is broken down into its syllables using a hyphen and then the Carriage return key must be pressed, so that two Flandgriffc are required until the other Control can take place again via the recording medium.

The invention is therefore based on the object

in a device for automatic line breaking in a record-controlled typewriter a design of the edge zone that can be adapted to the respective requirements, also known as the editing zone called to enable.

This object is achieved according to the invention by what is stated in the characterizing part of claim 1 Features solved.

Appropriate embodiments are set out in the subclaims compiled.

The advantages achieved by the invention are based on the one hand on the fact that in the editing zone Character yahl can be changed as you like, for example, if the Document contains a large number of long words. Also when inserting drawings, Photographs, diagrams, etc. in a document, it may be useful to measure the length of the editing zone in which the actuation of certain keys automatically triggers the carriage return, to make it variable. Because should For example, insert a drawing or sketch near the right edge of a sheet of paper while the area to the left of this drawing is described in the usual way, so this can only be done in the known devices by the fact that the recording-controlled typewriter is stopped by hand at the desired points. In the case of the typewriter according to the present one In the invention, however, the third margin stop can be moved to the left to such an extent that, for example if you press the space bar, the automatic carriage return results. This leaves a certain, optional adjustable range for such insertions freely.

Another major advantage is finally in the fact that is triggered in the / wide area of Wagenrück- si running also automatically when a / for separation of a word is entered into its syllables serving hyphen. This represents a significant improvement in comparison with the known devices, since with them, after pressing the w hyphen av.e, the carriage return also had to be triggered manually.

The invention is illustrated below with reference to Embodiments explained in more detail with reference to the schematic drawings. It * "> shows

In F 1 g. 1 is a common, electrical, calibration-controlled Typewriter shown in which a device for automatic line breaking according to of the invention is used; it is located between a left margin plate 15 and one right margin stop 10 a third margin stop 4.

In detail, this typewriter includes a carriage 1, a line lock 2, a bracket 5, a Shift lever 6 for the Red'ficrzonc, an actuator 7, an angle lever 9 for operating the loudspeaker, an angled bell U, a holding lever 12 for the right edge adjustment and an actuating element 13.

The operation of this typewriter is to be explained below, with particular reference to F i g. 1A is referred to. In this figure are the left margin stop 15 and the right margin stop 10 as well as the third margin stop 4 for changing the editing zone width shown in certain changeable positions. The area from the right side of a Editing zone lever 3 up to the right margin stop 10 is referred to as "editing zone" by means of a the redigierzone lever 3 coupled microswitch is determined whether the one carrying a write head Car 1 is or is not in the editing zone.

The carriage 1 is moved and operated as a function of the code recorded on a perforated tape or tape. Running the carriage on the third edge of plate 4 by, the sensing lever of the car 1 comes with the Redigierzonenh ^"! Iel 3 of the third edge of the plate 4 in Fingriff, in turn, the volume work lifting! Of Redigierzonenhebels 3 in engagement with the projection of the line lock 2 occurs. The The bell lever presses the crossbar 5 while the editing zone lever 3 blocks the angle lever. If the crossbar 5 is pressed down, the switching lever 6 for the editing edge attached to it rotates clockwise, so that the inclined actuating element 7 is attracted and a microswitch 8. The setting of the device for automatic line breaking within the editing zone is now complete.

When the typewriter is operating in a recording-controlled manner, a certain character, for example the character for the space bar, appears in the editing zone. so the car is automatically brought back to the left edge. If a word is to be split, the hyphen key is pressed so that a hyphen is written. In this case, the carriage return signal (CR) is generated when the binding direction key is pressed in order to return the carriage to the left edge.

If the carriage 1 runs beyond the right margin stop 10, the carriage's feeler lever comes along .nit the Lever 9 so engaged that the Läutverkbügcl 11 is pressed. As a result, a microswitch 14 is closed by a lever 12 attached to the bracket 11, so that the tape reader (not shown) and thus also the carriage is stopped. Will now the If the hyphen key is pressed down by hand, the car is automatically brought back to the left edge.

F i g. ? shows a detail of the typewriter according to F 1 ti. I. About how the editing zone lever works 3 / u explain; this redigierzone lever presses on the cross bracket 5. whereby the microswitch 8 is actuated will.

Fig. 3 shows a detail of the typewriter according to L to the function of the microswitch 14 to explain when the carriage 1 comes into engagement with the lever 9 of the right margin stop, whereby the Tape reader is stopped.

In Fig. Fig. 4 is a circuit for controlling the automatic line breaking device shown; a circuit 16 is switched on, if editing is to be carried out in the case of record-controlled operation; will the

Circuit 16 is switched off, so the electric typewriter works like a normal typewriter, is therefore not controlled via a recording medium.

The binary numbers supplied to the typewriter by a punch tape reader 17 are converted into letters and digits in a matrix 18. If a space bar signal (SP) and a carriage return signal (CR) are found in this sequence of digits, corresponding signals are generated and AND gates 19, 2fr, 21 and 22 are supplied. Output signals are obtained from these AND gates when, in addition to the space bar signal (SP) and the carriage return signal (CR), a signal from the circuit 16 for switching on the editing and a signal EZ == I is on

the AND gates 19 to 22 are applied; the signal EZ = I indicates that the carriage 1 has passed an editing margin circuit 23 and has entered the editing zone.

Depending on the output signals of the AND gates 19 to 22, the carriage return carried out.

To perform hyphen control, the hyphen key becomes a on a particular syllable Word printed on the written line or the hyphen code from the perforated tape or strip read out; as a result, in the Matfix peeling 1 the Carriage return signal generated so that carriage 1 is returned to the left edge.
