JPS60239846A - Method for forming list of contents stored in cassette - Google Patents

Abstract

PURPOSE:To enable an operator to observe the 1st of the contents stored in a cassette simply without any specific processing by forming the list of files stored in the cassette in a document memory. CONSTITUTION:The formation of the list of the contents of the cassette 8 is specified through a keyboard 2 and a cassette device 9 is operated so that an external speaker is actuated. The device 9 reproduces the contents of the cassette 8 and outputs the reproduced results successively. Each successive output signal is checked by a file identifier storing part 7 and its file identifier is extracted and stored in a document memory 3. At the storage of the file identifier, the sequential information of the extracted file, the sort of the file, the file No., the titled of the document, and the number of lines are also stored in the document memory 3. Check data are applied to the end of the file, and if an error is detected at the check of reading, the existence of the error is displayed on a position indicating the number of lines of the document.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for creating a list of contents stored in a cassette, particularly,
A cassette for storing the contents of the document memory, character patterns, kana-kanji conversion control information, etc. as necessary in a portable document creation device in which a keyboard, display, and printer are integrated and formed in a compact size. This relates to a method for creating a list of stored contents. A document creation device that is portable and required to input, store, display, edit, and print has a small storage capacity for storing documents. In addition, the document memory is originally equipped with the processing device to display and print the contents of the document memory, and the present invention enables the function to be improved by creating a list of contents stored in the cassette in the document memory. The contents stored in the cassette can be easily grasped in order to make effective use of the cassette.

[Conventional technology]

In recent years, Japanese typewriters have been rapidly developed, and various types have been offered on the market. Most of them are data processing systems equipped with a keyboard, display, external storage device, and printer, and although small, microcontrollers perform a considerable amount of processing.For example, they have overlay functions and automatically run programs in memory. The processing is carried out by changing various ways. Therefore, conventionally, an external storage device is connected as an essential device, such programs are stored in the external storage medium, and automatically overlaid as necessary.
Created documents are stored in the required location while creating a table of contents.

Therefore, if a user wanted to know a document stored in an external storage medium, all he had to do was display the table of contents page on a display or print it out.

[Problem that the invention seeks to solve]

However, as mentioned above, document creation devices that are low-cost, portable, and have multiple functions are configured to operate without an external storage device, and are not required to be connected to an external storage device, making them more compact. Therefore, the conventional method of using an external storage device is not possible, and a method is adopted in which the document content of the document creation device is simply stored in, for example, an audio cassette according to instructions from an operator. This means that a home tape recorder can also be used as an external storage device, which is very desirable since it means that the external storage device, which is usually a high cost factor, can be made at a low cost.

Although this is preferable, as time passes, people tend to forget what contents and what identifiers were used to store the contents in the cassette. Reading from a cassette depends on the identifier, so in such cases, you have to repeat trial and error by setting an appropriate identifier, reading it, and if it is incorrect, setting another identifier and reading it again. In addition to taking time, a situation may arise in which the identifier is not found.

[Means for solving problems]

In the present invention, a list of contents stored in a cassette of a cassette used in a document creation device having a function of storing data input from a keyboard in a document memory and a function of outputting the contents of the document memory is created. In the method,
A cassette that is a readout unit from a document creation device and stores a file that includes at least a file identifier specified by the document creation device at the time of reading, and file content that is the substantial content used by the document creation device. , a cassette device that sequentially outputs the contents stored in the cassette, and a file identifier storage means that extracts a file identifier from the sequentially output stored contents of the cassette and stores it in a document memory, The above problem is solved by creating a list of files stored in the cassette in the document memory.

[Effect]

That is, in the present invention, the contents stored in the cassette are played back by an audio cassette tape recorder, etc., and sent to the document creation device, and the file identifier etc. are extracted from each file from the sent data string. and store it in document memory.

This document memory originally has the function of outputting its contents to a display or printing it because of the nature of the document creation device, and it is possible to use this function as is.
Therefore, it is possible to easily show the list of contents stored in the cassette to the operator without performing any special processing.

〔Example〕

FIG. 1 shows an embodiment of the present invention, in which 1 is a document creation device, 2 is a keyboard, 3 is a document memory, 4 is a display, 5 is a printer, 6 is a control unit, and 7 is a file identifier storage processing means. , 8 is a cassette in which files are stored;
9 is a cassette device for reading and writing from the cassette, and 10 is an interface section for using the counter device in the document creation device 1.

That is, in the document creation device 1, the control unit 6 normally operates based on a signal from the keyboard 2, and data corresponding to the input signal is stored in the document memory 3. That is, the operator creates a document in the document memory 3 by operating the keys on the keyboard 2.

The contents of the document memory 3 can be viewed on a display 4, and when the document is completed, a printer 5 prints the contents of the document memory 3 on printing paper. Although not directly related to the present invention, in order to provide a compact and low-cost document creation device, the display is the size of a few characters, the document memory 3 has only a capacity of, for example, A42 pages, and an external storage is provided. It also does not have a function to automatically overlay the contents of an external storage device as program processing progresses so that it can operate without a device. Therefore, if the operator creates another document after printing the created document, the document memory 3 will be overwritten, and the old document contents and the document memory 3 will be erased.

In this case, even if a part of an old document is to be corrected, the entire text must be entered from the keyboard 2, which is inconvenient to use. Therefore, the contents of the document memo + J 3 are stored in a cassette-type magnetic tape (hereinafter simply referred to as a cassette), and control is performed to read the document contents from the cassette into the document memory 3 as necessary. . In order to facilitate this, it is more preferable to use an audio cassette so that the audio cassette device can be used. An audio cassette device stores a signal from a microphone on a cassette, converts the data on the power source into an electrical signal, and outputs the electrical signal.

When storing the contents of the document memory 3 in the cassette, the document number specified by the operator is entered in the file as part of the identifier; conversely, when returning the document contents from the cassette to the document memory 3, the operator keyboard 2
The document number to be returned is specified in .

The cassette stores not only the contents of the document memory 3 but also character patterns created by the operator and priority word information regarding word conversion at the end of document creation. Of course, an identifier will be added at that time as well. Therefore, an identifier is essential for reading them as well.

In the present invention, an instruction is given to create a list of cassette contents using the keyboard 2, and the cassette device is operated so as to make an external speaker sound. The cassette device begins playing the contents from the cassette and outputting them sequentially.

The sequential output signals are checked by the file identifier storage processing unit 7, the file identifier is extracted, and the document memory 3
Performs the process of storing it in . At that time, the file identifier is
Since the file type and the number assigned by the operator are included, the order information of the extracted file, the file type, the number, and in the case of a document, the title of the document and its line number are also stored in the document memory 3. Since check data is added at the end of the file, the read information is checked, and if an error is found, a message indicating the error is displayed at the position indicating the number of lines in the document.

FIG. 2 is a diagram showing a storage format in a cassette. On the cassette tape 27, first the league part 21 lasts for about 10 seconds, then the header part 22, the document control data part 23, the data part 24 which is the actual file contents, and finally the trailer part 25, which is one part. A file 26 is formed. The league part 21 is used to indicate the beginning of the file, and even if there is a slight difference between the time when the read instruction is given by the keeper F-2 and the time when the cassette device 9 starts to operate and send out the read signal. It is also something that cannot absorb that difference.

The header section 22 includes a file type (document/character pattern/word conversion information@) and a number assigned by the operator. In the document control data section 23, in the case of a document file, as a title, the words in the document memory 3 are sequentially looked at from the upper left corner of the created document to the right, and the first non-blank word is marked with an asterisk (*). The first word includes up to the 25th word (including blanks), and in addition to these, it also includes vertical and horizontal direction information, left end position information, right end position information, etc. The data section 24 also contains character information and control information on the display 4 as the contents of the document.

The trailer section 25 is a file end instruction section that lasts about 1 second.

FIG. 3 is a detailed embodiment of the invention. In the figure, the same symbols as in the previous figure indicate the same things as in the previous figure, 31 is a signal receiving terminal from the cassette device, 32 is a conversion circuit to a digital signal, and generates a data signal and a clock signal from the received signal. do. 43 is a fixed pattern generator. 3
3 is a distribution unit, and when the reader detection unit 34 detects the reader unit 21, the file type and file number from the header unit 22 are extracted, and the document number counter 39 is set by the recent unit 40. It is counted and amplified from the cleared state of "0" and becomes "1". Among the contents of the document control data section 23, the title portion is detected by the title detection section 36.
Extracted at. Then, the data in the data section 24 is output from the distribution section 33, and a parity check section 37 checks the vertical parity of the data. The final data is vertical parity, and if it is reproduced correctly, its value will be all O's, so by checking whether it is all 0's, it can be determined whether or not the reproduction was correct. If it is incorrect, a fixed pattern "medium error" is generated. The clock signal corresponds to the number of data, and the clock signal is counted in synchronization with the parity check, and the number of lines in one document file is counted based on information on the number of characters in one line and line feed information.

The trailer section 25 is a trailer detection section (not shown).
When detected, the "cassette contents list" is stored in the document memory 3 in the first line from the fixed pattern generator, and a line feed is performed twice to leave one line empty. Next, in the storage position of the document memory 3 corresponding to the content of the document number counter 39, the fixed pattern generator writes "隘" and the content of the document counter 39 "1" in the first line, followed by the header detection section. The file type "document" and "01" which are the outputs of 35 are stored in the document memory 3.

Furthermore, if the parity check unit 37 does not display an error, the title detection unit 36 extracts the extracted title “*Patent Manuscript”, the output “22” of the line number counter 42, and the fixed pattern “line”. The content is stored in the document memory 3 at a location corresponding to the content of the document counter 39. However, if the parity check section 37 displays an error, the title detection section 36
The extracted titles, the output of the line number counter 42, and the "lines" of fixed number turns are not stored.

Then, the cassette storage device does not stop (the data on the cassette continues to be reproduced and applied to the signal input terminal 31, so the next file will be processed in the same way.

FIG. 4 is an output example of a cassette contents list.

In Figure 4, the second file stored in the cassette is a dictionary designated as number 01, and the third file stored in the cassette is a document designated as number 02. , the title of the document is "*Latest product development plan" (actually, the first line of the document indicates "Latest product development plan") and the number of lines is 40. It shows that it is something. Hereinafter, the sixth file stored in the same manner is a document, and the number is designated as 03, which indicates that an error occurred during reproduction of the data portion.

In this manner, when an error occurs, the title and line number are not stored in the document memory 3, but instead a fixed pattern of "medium error" is stored.

As mentioned above, the contents stored in the document memory 3 can be corrected using the keyboard 2, viewed on the display 4, or even output to the printer 5 using the document creation function that the document creation device originally has. can do.

〔Effect of the invention〕

According to the present invention, even if the number has been stored in the cassette storage device but has been forgotten, it becomes possible to know the number. Also, since you can know the number of lines, it is possible to know where on the cassette the force is stored, and
(Dictionaries and characters) Always use a specified line) If you want to store a specified file containing the contents of the cursor and throat in a document processing device,
For example, if you use the fast-forward function of the swivel/gutter device to advance the swivel/gutter to a nearby location in advance, you can store the file in the target document processing device in a short time.

That is, in order to output the list, the information is sequentially scanned using the file J and only the necessary information is stored in the document memory 3, so that there is no waste in the processing, resulting in efficient data processing.

Furthermore, since the document is stored in the document memory 3, the printing function, display function, editing function, etc. that the document processing device originally has can be used as is. Because of this editing function, it is possible to create a list of file contents with necessary information added, which is convenient for use as a display display of the contents of the cassette and attaching it to the cassette.
