Description

The present invention relates to a device for

  word processing or text editing using a micro-

processor.

  As is well known, a milking device

  text, classic, comprises a keyboard with a number of keys for letters, numbers etc, these keys being distributed as those of a typewriter keyboard, usual, a microprocessor forming a signal processing circuit, a display device to display

  the text introduced by the keyboard and a recording device

  text data for storing the text data on a recording medium such as a tape or a magnetic disk. In a text processing device described above, it is possible to modify or change a selected sentence or text introduced with the help of the keyboard, to put it according to a

  appropriate format while monitoring the display.

  After this editing operation, the final text is saved on a tape or disk. We can also

  print on paper if necessary with an electronic printer

cudgel.

  These word processors, known, use

  usually read a disk and are powered by

  ternative and in addition they ensure the display of a complete page or a complete line, so that it is very difficult to

  take them outside the offices.

  The object of the present invention is to create an apparatus

  portable word processor, with a half-way display

  line, equipped with a keyboard and tape recording device, a pair of display control buttons on the front panel to choose either the first or the second half of a line of text, and in such a way that the overall dimensions of this device correspond practically

to a sheet of A4 paper.

  According to the invention, the treatment apparatus of

  The text must be able to be powered by batteries and recorded

  tracing data page by page on the tape of a micro-

  cassette. When a written document is required, the

  word processing provides output signals to a printer

mantis.

  DETAILED DESCRIPTION OF A PREFERENTIAL EMBODIMENT

  Figure 1 shows a control panel of an exemplary word processor according to the invention; the reference 1 relates to a keyboard with several keys aligned as the keys of a conventional typewriter. The word processor according to FIG.

  display of half a line of characters, 2, with liquid crystals

  des, allowing to display 40 characters each formed of 5 x 10 points. The upper right side of the panel includes a microcassette tape recorder 3 for recording and / or recording.

  reproduction of the user's voice and text data.

  The tape recorder 3 is manually controlled using the function keys 4 and the text data is entered using the keypad 1 or from the tape recorder 3, for editing and modifications using command keys

text editing 5.

  The word processor according to the invention further comprises a loudspeaker 6 below the display 2

  and a microphone incorporated above the tape recorder.

  Word processor can be powered by batteries; the reference 8 according to Figure 1 relates to the on / off switch. A block diagram of the word processor described above will be described with reference to FIG. 2; according to this figure, the block 10 of the keyboard comprises a key encoder 11 for the keys of the keyboard 1 and the text editing control keys 5. The signals of the key codes, coded, are applied to a central processing unit (CPU) 12 via an interface 13 also connected to a display block 14 having a half-line display buffer 15 (in the case of this

  example, the half-line corresponds to 40 characters) and a

  half-line display 2, liquid crystal.

  There is a micro-cassette interface 16 on the control panel 18 with a micro-cassette; this interface is

  connected to the CPU 12. The micro-control panel

  cassette 18 includes a tape recorder or recording apparatus

  3 and the functional keys 4 corresponding to it.

  lay a circuit of silence 17 which makes it possible to suppress

  sea the sound of a data signal from the speaker 6 by a

programmed control.

  The total operation of the word processor is set by a control program written in a read-only memory (ROM) 19 connected to the CPU 12 CPU.

  micro-cassette control panel 18 includes a converter

  a data state (not shown) which transforms a logic state "1" into a burst signal of 600 Hz and a logic state "O" into

  a 300 Hz burst signal and vice versa.

  The word processor according to the invention comprises a text buffer 20 with a capacity of 1800 bytes. The size of the memory 20 depends on the average number of characters entered in the case of a letter of correspondence

  on a sheet of paper of A4 size.

  The operation of the above text processing apparatus will be given below: In the above apparatus, when the desired text or sentence is entered from a keyboard 1, the corresponding coded signal , is transmitted by the interface 13 to the buffer memory 20. As indicated, the memory 20 has a capacity which corresponds to the coded signals of a page, that is to say for example 1800 bytes. When the text data stored in the memory 20 is to be recorded on the tape of a

  micro-cassette, the operator enters the registration orders

  by pressing the keypad 1. The corresponding command signal

  dant is supplied to the CPU 12 CPU; in response to the order of the CPU 12, the text data stored in the memory 20 is read sequentially for application to the recording apparatus 3 in the form of

  salvo, sound via micro-interface

  16. At this moment the order is also provided at

  16 by the CPU 12, so that the magneto-

  phone 3 goes into recording mode. At this moment, immediately

  before reading the buffer merge text data

  , a start code signal and a data request signal.

  with a predefined synchronization signal, a block number, etc. are provided by CPU 12 at the central station.

tape recorder 3 which records them.

  Besides not only the text data but

  also the audio signals of the microphone 7 can be recorded.

  3 by acting on the function keys 4. Indeed, when the operator pushes the recording switch REC among the function keys 4, the unit

  CPU 12 receives a corresponding order signal and applies

  than an order to the tape recorder 3 for it to go into recording mode. During the recording of the data of the text of the memory 20, the audio signal is silenced by the silence circuit 17 under the effect of the order signal of the unit

  CPU 12, to avoid any noise noise.

  Further, when the conventionally read read switch "PLAY" is pressed among the function switches 4, the corresponding read command signal is applied to the CPU 12 CPU. the tape recorder 3 so that it goes into play mode. Immediately after the reproduction of the start code signal and the data control signal, the text data is reproduced and is supported in the

  20. At the reproduction of the text data of the micro-

  cassette, the silence circuit 17 actually removes all

  the annoying noise of the loudspeaker 6.

  When the text data is entered by the keypad 1, the character codes are stored sequentially in the memory 20 with a carriage return code for each of the lines. In the case of the execution of

  display, basically the 40-character code signals

  from the carriage return code are transferred to

the display buffer 15.

  Normally the number of characters in a line is 80 in the case of a sheet of dimension paper

  A4. As indicated, the word processor according to the invention

  The coded text data stored in the memory 20 is provided by the CPU 12 to the display buffer 15 and is displayed on the display device. half line 2. In

  these conditions, as the display device 2 can display

  expensive only 40 characters at a time, the operation of the display device 2 begins with the first 40 characters of a line and if the number of characters introduced by the keypad 1 exceeds 40 characters, the last 40 characters are

displayed second.

  When one of the display control keys a, 5b among the text editing control keys 5 is depressed, the first or second half of data of a selected line, stored in the memory 20, is provided. selectively to the display buffer 20 to be displayed by the display device 2. The sentence can be modified or corrected using the switches 5 and the keypad 1. The operations to modify or correct a sentence

  are almost the same as those of a milking device.

  text according to the prior art.

  In the above apparatus, to display the portion immediately preceding or following the displayed portion, the button of the switches 5 is actuated to ensure the partial change. Before and after this key, there are two keys 5a, b which are respectively represented with symbols in FIG. 1. When the keys are actuated, the CPU 12 performs the following operations: FIG. 3 shows the flowchart from the program

  in memory in the ROM.

  In FIG. 3, when the block [13 of an appropriate key is actuated, the block E2J distinguishes whether the operation corresponds to a change key of a display part, for example the last one (ie say key 5b) and in block [3J we check if the operation corresponds to the key of

  change of a display part for the front part (that is,

  to say the key 5a). When the operation does not correspond to the two cases above, other programs are performed on block [4], then we return to block t. When in block [2) it is found that the commanded key is the change key of the display part for the last part (key 5b), there is a distinction in block f1-3 if the display part is the first half of the line or not. If the display part is the first half, in block! 2i, the second half of the buffer 20 is transferred to the display buffer 15 and it is returned to block E. In addition, when the displayed is the second half of the line, on the block Eil, the text data for the first mc-iti of the next line are transferred aa memore-tapon display 15 at block 5 i then we return to the block When one distinguishes at the level of the block r3l that the request corresponds to a change ponr! - 2arr e previously displayed, we distinguish in the block z2l If the displayed part is the second half of the line or not. If the displayed part is the second half of the line, in the block [22, the first half of the text buffer is transferred to the display buffer 15, then it returns to

  the ruled block. When the displayed part corresponds to the first

  half of the line on the block [21, the data of the second half of the previous line are transferred to the display buffer 15 at block 23, then back to block 11

  Figure 4 shows more clearly the functioning of

  of the invention. This figure consists of Figures 4A, 4B
