The invention according to the parent patent allows dia to be used in the inscribed text sections afterwards to insert, delete or rearrange after the dictation has taken place, using the associated track codes in the main memory rearranged, deleted or inserted v / earth. The track codes are then read out in the new order and in this new order the associated memory tracks and the associated text sections are read out. It is easiest if you put a single sentence of the text dictation in each memory track, then you can Rearrange and delete text sentence by sentence and also JDinschtibe sentence by sentence make. The sentences do not have to be grammatical sentences, they can also be others Act word sequences or just search letters.

When operating such a dictation machine, it may be desirable to move from one sentence track to the next to pass over, for example to listen to the previously dictated sentence again. It is our task to make this possible in a convenient way a further development of the invention according to the parent patent.

The invention is characterized in that a hand-held microphone is provided with a sentence control key for switching on of the carriage drive step by step from track to track transversely to the longitudinal extension of the storage tracks,

The puncture of the controls 33 »35, 36 and 57 results from the following text.

With 12 is a tone generator, with 13 a tone detector, and with 2a the paragraph logic and with 2b the sentence logic of the main memory 2 designated.

The tape store 1 works with an endless magnetic tape with a circumference of approximately 150 cm. On this magnetic tape, a number of paragraphs of 30'8 sentences, i.e. a total of 128 sentences in 128 magnetic tracks arranged next to one another, can be recorded. Access to the individual tracks is possible independently of one another. The tracks that are used to adjust the magnetic transducer to the individual tracks are explained in more detail below.

The main memory 2 contains approximately 512o memory positions for storing digital codes of the addresses under which each Sentences are recorded in the tracks of the magnetic tape. The main memory 2 has four bit positions A, B, C and D, of which the three bit positions A, B and C are used for the ordinal number of the sentence track, while the fourth position D indicates whether the sentence segment in question has been received by the operator has been discussed or not. If sentences are deleted, pasted or moved within paragraphs, then the corresponding addresses of the relevant Records in main memory 2 moved. The address cpden of the individual Sentences of this text are then entered in the main memory, even after the operator has already spoken their words Text sat two so rearranged several times. the shelf arrangement to which the operator has finally rearranged the text.

The main memory 2 has four bit positions E, P, G, H to identify the location of the relevant paragraphs in the main memory and four ireltore bit positions J, K, L, M to indicate under which section the relevant paragraph

is written down on. ViFenn moved the paragraphs, used or deleted, then the ordinal numbers recorded in the four bit positions B, F, G and H become the relevant Paragraphs changed accordingly, so that the new ordinal numbers correspond to the sequence aimed at with the university regulations of the paragraphs.

If the operator depresses the downshift key 23, then the device gets into a switching state in which it can record a completely new sequence of sentences and paragraphs. i The main memory 2 is loaded as if all the segments are read out in the sequence solltorf but the segments are sämtlichst marked as unused. The operator now switches on the recording control circuit 38 by means of the switch T and thus switches the device to recording mode. If the pressure switch 8 is now depressed for dictation mode, the magnetic tape moves in the tape store 1 with respect to a magnetic transmitter and the text spoken into the microphone 17 is written down. The address codes of the sentences of the first paragraph of the sentence memory 42 are stored in the main memory 2. The sentence toggle circuits 50 and the paragraph toggle circuits 51 are switched to "1 ⁿ . The display lights ä under the sentence selection key 26, which is labeled with the number 1 and under the paragraph key 25, which is labeled with the number 1 light up. The addresses of the Sentences being processed are stored in the sentence memory 42. It should be noted that the entire magnetic tape had previously been erased as a result of pressing the Rüokechalt button 23 in a manner as will be described in detail below the dictation key 8 is activated and an amplifier for amplifying the microphone streams is switched on and the amplified microphone streams

At the end of the sentence, the operator tilts the switch 8 backwards and presses the rear end of this switch, so that an end marker is triggered. An audio signal is recorded at the end of the track that has just been labeled. Once this has happened, the tape memory 1 automatically switches to the beginning of the next track on the magnetic tape. The selection switch 4o, the comparator circuit 41 and the record memory 42 are switched, the record memory rather 42 working together with the selection logic 44 which controls the operation of a step control circuit 46 and a motor control circuit 47. The transmitter is moved to the next track of the magnetic tape and the record memory 42 stores the fact that a record is now in operation in position 2 and that this record follows the record. The lighting of the sentence selection button 26 vdrd labeled with the number 2 is then switched to high intensity, while the lighting of the sentence selection button 26 with the label 1 is switched to low intensity. The main memory 2 is activated when. Information relating to a paragraph can be entered.

When dictating, the operator can omit sentence positions by pressing the sentence control key Io forwards, ih. based on Figure 3b pushes up. If the operator does this, a final marking tone is written into the sentence track and the tape memory, controlled by the step control circuit 46, is advanced to the next following track, while at the same time the magnetic tape, controlled by the photo meter 63, which scans a hole marking 67 of the magnetic tape, onto the Beginning

During playback, the audio signal recorded at the beginning of these sentence tracks the transmitter is switched to the next following track until text is recorded on these tracks.

A hand control 8o is drawn in at the top in FIG. The paragraph key 11 and the manual control θα interact with the sentence clapper postures 5o and the Abeatzkippechaltungen 51 and control the step-by-step progression of the main memory 2 so that it can store the localizations of the aSatzsegmente. The paragraph of the section memory 55 controls the indicator lamps of the paragraph keys 25 and the section indicators 57t if such are provided. Section indicators 57 are provided when it is desirable to select larger blocks of information, such as entire letters or the like. The sat memory controls the lanpen for the sat keys 26.

If the operator moves the switch 7 down, a short return is triggered. The magnetic tape then runs back a little along the recording that has just been made, opposite the transmitter. The switch 7 is spring-loaded against the downward displacement and, as soon as it is released, is pushed back into the middle playback position, in which the last part of the dictation just spoken can now be listened to. Meanwhile, the reproduction control circuit 6o controls the reproduction on the loudspeaker 17 or the loudspeaker 16, depending on how the talk button 15 is switched. The changeover switch 7 is not set-oriented, ie it provides the reproduction of information within the set that is currently in operation. The operator cannot therefore access the start of the record that is currently in operation with the switch 7.

When the sentence control key Io is operated in the backward direction, the magnetic head is returned to the beginning of the sentence which is currently in use. This process is also referred to in the following as long reverse. For this purpose, the set control button Io only needs to be pushed down once. If you press the sentence control key Io one more time, the memory switches back to the previously recorded sentence, whereby unlabelled sentence tracks are skipped again. If you keep pressing the sentence control button backwards, the memory switches back segment by segment and the lights under the sentence selection buttons 26 show the current status. If the system is in the recording mode, it will continue to rewind until the operator lets the sentence control key Io go up and the system then displays the selected segment and stops. If, however, the system is in playback mode, the selected segment is noted and playback starts again with the sentence reached at the end of the receding process. A corresponding operation results when the paragraph key is depressed, which results in an intermittent displacement of the magnetic head with respect to the magnetic tape.

Press the sentence control key Io and the paragraph control key 11 upwards, then the memory advances in blocks or in blocks forward.

The operator can arbitrarily select sentences and paragraphs. For this purpose the sentence control key Io and the Paragraph control button 11 pressed so that the transmitter gradually Runs track by track over the magnetic tape until it reaches the one to be selected Has found a sentence or paragraph by pressing the relevant paragraph key 25 or sentence selection key is marked.
