Description

The invention relates to a circuit arrangement for automatic information recording in encoded form, with an input device for recording the encoded information characters a tape-shaped recording medium, read-out means for reading out the encoded character information from the tape-shaped recording medium, a printer for printing out the information characters to a recording paper and a controller for controlling the printer.

DE-AS 10 86 072 discloses a circuit arrangement for recording information with writing or printing devices known in which the information to be printed out before it is printed is cached, each information to be corrected is identified by special correction signals which are to be detected by a detector device. When acquiring these correction signals then instead of the information to be corrected, information stored in another memory is used read out and printed out. This known device uses for this purpose z. B. a Tape storage with two different tracks, on one track the information to be recorded and on the other track the information to be recorded instead of parts of the information to be corrected corrected information to be recorded on the first track is stored. When a correction signal is detected At the same time, it is determined at which point of the first track stored information by at which point the information stored on the second track is to be replaced and at which point on the first track with not to corrective information should be continued. But this has a relatively high The result is expenditure on storage capacity and control devices for searching for the storage addresses.

The object of the invention is to provide the circuit arrangement of the type mentioned in the introduction Simplify and develop so that with her depending on one between two successive Words arranged function codes are to trigger certain functions, such as. B. one to be corrected Replace information with correct information or, if one occurs, the printer to shut down corrective information.

In a circuit arrangement of the type mentioned, this object is achieved according to the invention in that the information characters in communication with the input device on the tape-shaped recording medium with pause codes that divide the individual words can be recorded, each time after If incorrect information was recorded, an error code was entered instead of the pause code below and is recorded, and that the control device of the printer has a buffer memory for temporary storage of the character information, means for detecting the pause and error codes in the buffer memory and a device responsive to these codes, by means of which the in the word of the character information stored in the buffer memory depending on whether the dem The following code in question is a pause code or an error code, is printed out or deleted.

Since, according to the invention, both the writing and the reading out of the information with the aid of a takes place on a single recording track, this results in a particularly simple circuit arrangement. In the case of the new arrangement, a respective neighboring word of the character information can be separated from one another pause code separating on the tape-shaped recording medium by an error code are then replaced when recording the information characters on the tape-shaped recording medium the operator makes an error. Immediately after the error code, the Operator record the correct word on the tape-shaped recording medium, which then when the error code is detected, the printer automatically replaces the previously recorded incorrect one Word is read out or printed out. Instead of the error code, the pause code can also go through a stop code are replaced, when detected, the printer interrupts its operation, so that then z. B. by manual intervention a wrong word can be replaced by a correct word.

In the following, preferred embodiments of the invention will be described in more detail with reference to drawings explained. It shows

F i g. 1 is a block diagram of an embodiment of the invention,

F i g. FIG. 2 is a plan view of a portion of the information recording tape used by the machine shown in FIG. 1 the device shown is pretreated or printed,

3 shows a block diagram of a modification of the invention and

F i g. 4 is a plan view of part of the tape for Information recording that is made by the device to according to FIG. 3 was printed.

The in F i g. 1 shown embodiment is so constructed that an error is automatically detected and is removed during the automatic printing when the printed on the recording tape 13 Information contains any error to be corrected

In the following it is assumed that the tape 13 to be attached to the reader 50 of the printing device 14a with the in F i g. 2 characters and code signals shown are printed, which correspond to the character information. If the in F i g. 1 shown on the belt 13 necessarily first the THE characters (space) and then the DOG characters (Space) must be printed, if the characters DEG (space) were printed by mistake, the code signal 011110 following the character G for changed the distance to an error code signal 011110 and the correct DOG (spacing) characters are printed. To get the code signal 011100 for the distance ju to change into a code signal 011110 for an error, a key in the character input section can be designed as an error code key, so that the error key is pressed instead of the distance key. On the other hand, it is possible to change the code by printing the Change spacing codes immediately and then extend a short line that extends the second bit down to the bit with the lowest value of the distance code printed out on the tape 13.

When the tape 13 bearing the information shown in Fig. 2 is given to the tape reader 15, the signals of the character information THE (distance) are successively sent to a buffer memory 101 in sent in the order mentioned above. When a decoder 102 receives this distance code signal 011100 is detected, its output signal is an AND gate circuit 103 free, whereby the contents of the buffer memory 101 in another buffer memory 54a is transmitted. When this buffer memory 54a receives the code signal 011100 for the distance, generated the decoder 56a provides an output signal to the printer 62a which is an instruction signal for printing represents. Based on this print command signal, the printer 62a prints the characters in a space between a left and right margin position. Although the contents of the buffer memory 54 each When character information input is changed, the buffer memory 54a stores interleaved with spacing codes Information, e.g. B. three character information T H and E. After completion or completion of the printing of these characters, the information stored in the buffer memory 54a is replaced by a The clear signal sent from the printer 62a to the buffer memory 54a is deleted.

After the character information D E and G are entered into the buffer memory 101, a The output signal of the decoder 104 is output to the clear input of the buffer memory 101 when the Decoder 104 detects a wrong code, thereby erasing the wrong character information D E and G will. As a result, this misinformation is not applied to the printer 62a. If correct Drawing information DOG together with the Code signal for the distance are given to the buffer memory 101, the UN D gate circuit 103 is through the code signal for the distance or space released and thereby the correct character information applied to the buffer memory 54a.

As described above, such incorrect information can be automatically stored in the buffer memory 101 by entering an error code instead of a function code, such as a distance or Space codes are eliminated even if incorrect information is sent to the character entry section were given. As a result, the information on the tape 13 can be correctly printed on the recording paper without interfering having to leave manual operation, since every misinformation or every incorrect information is automatically removed.

Although the in F i g. 1 embodiment shown, the printing process is prevented when the on the character information printed out on the tape 13 contains an error code signal, it is also possible to use a Use stop code signal in place of an error code signal, so that the operation of the printing device is stopped when a stop code signal is detected in order to manually activate the print correct characters. The use of the stop code signal is also in such a way automatic printing of direct mail effective, in which, for example, only the addresses are different from each other while the main body of the message is the same. With such a Application, a stop code signal is used at a position directly in front of each address. It is then possible to send a large number of messages with the same content, each time only manually entering the Addresses are printed when the work of the printing facility is interrupted to print.

In Fig. 3 shows an example of a printing device 14b which is designed for the use of a recording tape 13. The tape used in this modified embodiment is printed with the same information as shown in FIG. The codes representing the digits 0, 1 and 2 printed on the tape 13 are the same and the space code S following the digit 0 is the same as in FIG. 2, ie 01HOO. To stop printing after the digits 1, 2 and 2 have been printed, a stop code 111100 is printed between the digits 2 and the character A. Since this stop code is different from the space code 011100 - the bit "0" with the highest value of this code has been replaced by "1" - it is easy to convert the code for the space into a stop code 111100 by extending the short On the other hand, instead of extending a short line corresponding to the most significant bit, the part of the band with the short line can be colored black for as long as a code equivalent to code 111100 can be obtained.

The tape 13 prepared in this way is set in the tape reader 50; then a

Start signal to the tape feed 111 from a Key input device 110 applied so that the information on the tape 13 by the tape reading device 112 read out consecutively. The information read in this way will be over an OR gate 113 is given to a buffer memory 101. When the decoder 102 detects a signal or finds which corresponds to the code S for the space, the content of the buffer memory 101 is over the AND gate circuit 103 is transferred to another buffer memory 54a and in this buffer memory stored, as already mentioned in connection with FIG. 1 was described. The in the buffer memory 54 a Stored information is displayed in the same way as was explained in connection with FIG. 1 the recording paper is printed.

If the information given by the tape reading device 112 via the OR gate circuit 113 to the buffer memory 101 corresponds to a stop code, this stop code is decrypted by a decoder 114, so that this decoder 114 sends a command signal to the tape feeder 111 to stop the tape feed. For error correction, a clear signal is applied from the key input device 110 to the buffer memory 101 in order to clear the content stored in the buffer memory 101. New character information is then given from the input device 110 via the OR gate circuit 113 to the buffer memory 101. When the code for the space after the character information is given from the key input device 110 to the buffer memory 101, the decoder 102 generates an output signal which enables the AND gate circuit 103 to thereby display the character information obtained from the key input device 110 was applied to the buffer memory 101 to be transferred to the buffer memory 54a. It is also possible to print a new character by manually operating the printing device after the tape feed 111 is stopped by applying a stop code to the tape feed. In this case it is on

ίο Place of supplying the necessary character information possible from the key input device 110, the characters by manual actuation of the keypad to print on the recording paper, the keypad being provided with the printer 62.

After the new character has been printed, a start signal is sent to the tape feeder 111 of the key input device 110, the characters A and B after the characters 1, 2 and 2 in Figure 4 to be printed.

In this way, when printing characters using the tape 13, it is possible to use the Interrupt tape reader when a stop code signal is detected, so that a correction of the printed Character as well as addition, deletion and confirmation of the information are easily carried out can be. In particular, it is possible to manually activate the code for the space convert to the stop code; after the tape has been provided or prepared, the

jo operation of the printing device without further ado check.
