Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device, and, for example, a sentence input from an input unit such as a keyboard in a document processing device is stored in a memory in association with a keyword, saved and registered, and then registered. The present invention relates to a data processing device such as a document processing device, the contents of which can be read by a keyword input from the input unit.

2. Description of the Related Art A conventional document processing apparatus is provided with an external storage means such as a floppy disk or a cassette with a built-in memory backed up by a battery in order to semi-permanently store a created text. Then, the text data is stored, saved and registered, and read out at appropriate times. At the time of this storage registration, a keyword name is made to correspond to each sentence, and by inputting this keyword from the keyboard device, the corresponding sentence data is read from the external storage means and re-edited.

Therefore, it is desired to interrupt the process of inputting a sentence and temporarily register it in such an external storage means. Conventionally, even in such a case, it is necessary to store corresponding to a keyword in order to store it in the external storage means. Therefore, when many kinds of sentences are input, the number of keywords increases, and the operation for reading is a prank. It becomes complicated.

In order to solve such a problem, it is conceivable that a predetermined store area of the external storage means is simply prepared, and sentences without keywords are stored and temporarily registered in this area. If so, the storage area that can be stored in the external storage means corresponding to the keyword decreases, which is not preferable.

It is an object of the present invention to provide a data processing device capable of performing temporary registration control without providing a fixed area for temporary registration with respect to temporary registration control of data such as sentences.

According to the present invention, an input unit for inputting data such as a document, a first memory for storing data input from the input unit, and a second storage for registering a plurality of data stored in the first memory A data processing device having a memory, wherein the second memory associates a first store area for storing a plurality of data, an address value of the data stored in the first store area, and a keyword of the data. A plurality of second store areas for storing the data stored in the first memory, and a third store area for storing only the address value of the data stored in the first store area, and storing the data stored in the first memory in the second memory. When the storage registration instruction is a keyword registration, data is stored in an empty address position of the first store area, and a keyword and an address value are additionally stored in the second store area. In the case of registration, data is stored in an empty address position of the first store area or in the address position of the temporary registration data when the temporary registration data is already stored, and the address value of the third store area is rewritten and stored. A data processing device comprising registration control means.

A registration key 12 to be executed, a call key 13 for instructing control to call a sentence already registered in the memory 7 to the sentence buffer 41, and an execution key 14 operated to execute the control instruction previously instructed. It has and. The memory 7 may be a floppy disk or a cassette equipped with a memory backed up by a battery or the like. These keys 11-1
When the user operates 4, the corresponding character code or the related code and the control code are generated from the keyboard device 1 and given to the processing circuit 3. The processing circuit 2 performs a processing operation according to a control program, which will be described later, stored in the read-only memory 3. The random access memory 4 includes (a) a text buffer 4 for storing the above text data.
1 and (b) a keyword is input by the character input key 11 when registering the data of the sentence buffer 41, the keyword buffer 42 for temporarily storing the data of this keyword, and (c) the memory 7 Buffers 43 and 44 for temporarily storing the address data and (b) buffers 45 and 46 for temporarily storing the number of bytes of the sentence registered in the memory 7 during the processing of the contents of ,
(e) Counter 47 for counting the number of bytes of text data
And (f) address pointers 48 and 49 for temporarily storing address data, and (g) a store area 50 such as various flag buffers. The printer controller 5 controls the dot printer 6. A display device 9 such as a cathode ray tube display device is controlled by a display control circuit 8. The printer 6 records the data of the text buffer 41, and the display device 9 displays the content of the text buffer 41.

The memory 7 may be a floppy disk as described above, or a cassette including a complementary metal oxide semiconductor random access memory backed up by a battery or the like. In this memory 7, a store area is defined as shown in FIG. In this memory,
A registration area 75 for performing a save registration which is a keyword registration and a temporary registration which is not a keyword registration, and a head address value A of a store area newly saved and registered in this store area
2, a store area 71 for storing 2; a store area 72 for storing the start address A1 of the temporarily registered text stored in the registration area 75; and a text stored and registered with various keywords in the registration area 75. A keyword table 74 in which the keywords are stored, and an index area 73 for storing a head address that can be newly registered in the keyword table 74 are included. No keyword is attached to the temporarily stored text having the head address stored in the store area 72. In the keyword table 74, keyword names and corresponding start addresses of the stored registration sentences A and B are stored in pairs.

The operation procedure will be briefly described. First, a desired sentence is input by the character input key 11, and the sentence is sequentially stored in the sentence buffer 41. When storing and registering this sentence with a desired keyword, a keyword name is input by the character input key 11 after the operation of the registration key 12, and then the execution key 14 is operated. The number of characters to be saved and registered in the text buffer 41, that is, the number of bytes, is counted and output, and the corresponding text data is registered in the registration area 7.
5 and the keywords are the keyword table 7
Stored in 4. When recalling the stored and registered sentence, the call key 13 is operated to input a desired keyword name and the execute key 14 is operated. As a result, the corresponding keyword name is retrieved from the keyword table 74, and this sentence data is retrieved from the registration area 75 in the sentence buffer 4.
1 is read out and stored. Further, when the character input key 11 is operated to temporarily register the input text, the registration key 12
Then, the enter key 14 is immediately operated without inputting the keyword name. As a result, the data of the sentence buffer 41 is recorded after the already-registered sentence with the keyword in the registration area 75.

Referring to FIG. 3, the character input key 1 of the keyboard device 1
1 is operated to input characters at step 110.
In step 111, it is determined whether or not the registration key 12 is operated, and if not, the character data input to step 112 is transferred to the text buffer 41 and stored therein so that it can be edited. A text input process is performed for this purpose. The contents stored in the text buffer 41 are displayed on the display device 9.

While looking at the display screen of the display device 9, the operator saves and registers the sentence data corresponding to the keyword, or sets the sentence to be temporarily registered without the keyword. Thereby, the number of bytes of the text data is counted. By operating the registration key 12 in step 100, a flag provided in the store area 50 of the random access memory 4 is set in step 101, and the registration mode for saving registration or temporary registration is set. To be done.

When temporarily registering, the execution key 14 is operated in step 120 without inputting a keyword name. In the next step 121, it is judged whether or not the mode is the registration mode, and if not, another process is performed. If it is in the registration mode, the process moves to step 122 and it is determined whether or not the data is stored in the keyword buffer 42. Since no data is stored in the keyword buffer 42 when the temporary registration is performed, the process proceeds to step 132 in FIG.

In the temporary registration operation, in step 130, the memory 7
The contents TMP of the store area 72 of the storage area 72 are read out, and thus the TMP has been previously registered temporarily.
It is determined whether or not the temporary registration area is formed. As will be described later, in the content TMP of the store area 72, when the temporary registration area is formed in the registration area 75, its head address data is stored, and if it is not formed, this content TMP is empty. When the temporary registration area is already formed in the registration area 75, the contents TM
New data is written in P and rewritten. If the temporary registration area is not formed in the registration area 75, the process proceeds to step 131, and the address data which is the content TEXT of the store area 71 is transferred as the content TMP of the store area 72. By the execution of this step 131, the address A1 shown in FIG. 2 is stored in the store area 71 and at the same time is stored in the store area 72. In the next step 132, the store area 7
The content TMP of 2 is transferred as the content STMP of the buffer 43 and stored in the sentence buffer 41 as described above.
The number of bytes of the text to be registered is transferred at step 133 as the content TEXTBYT of the read buffer 46. In step 134, the stored contents STMP of the buffer 43 and the contents TEXTBYT of the buffer 46 are added, in other words, the number of bytes of the registration statement is added to the start address of the temporarily registered store area, and the last position of the temporary registration area The address value is determined and stored as the contents STEXT of buffer 44. Furthermore, this buffer 44
In step 135, the content STEXT of the above is compared with the final address n of the memory 7, and when the content STEXT exceeds n, it is determined that registration in the memory 7 is impossible and error processing is performed. When the content STEXT is less than or equal to n, the content TMP of the store area 72 is transferred as the content AP1 of the pointer 48 to the step 136, and the content K of the counter 47 is reset at the step 137. Then, by the operations of steps 138 to 141, the sentences to be registered in the sentence buffer 41 are sequentially transferred and stored in the temporary registration area of the registration area 75. More specifically, in step 138, the content K of the counter 47 is incremented by 1, and
In step 139, the data of the text buffer 41 is stored in the address area corresponding to the content AP1 of the pointer 48 in the registration area 75. The data of the text buffer 41 has the number of bytes of the text to be registered. In step 140, it is determined whether the stored content of the counter 47 and the content TEXTBYT of the buffer 45 are equal, and the content AP1 of the pointer 48 is incremented by 1 charac- ter by 1 in step 141 until the contents match, and the transfer process is repeated. The content TEXTBYT represents the number of bytes.

When a match determination is made in step 140, the process proceeds to step 142, and the content STMP of the buffer 43 storing the start address value of the temporary registration area is stored in the store area TMP of the memory 7 by the step 132. Further, in step 143, the contents STE of the buffer 44 storing the address value which becomes the top address when the next new data is registered by the above-mentioned step 134.
The XT is stored in the store area TEXT of the memory 7. By such an operation, the registration sentence is stored in the registration area 7 of the memory 7.
The registered text before 5, that is, the text indicated by reference numeral B in FIG. 2 is temporarily registered.

The operation of adding and storing a keyword name will be described. When a character is input to input a keyword name, steps 110 and subsequent steps in FIG. 3 are executed, it is determined in step 111 that the mode is the registration mode, and the input character data is transferred to the keyword buffer 42 in step 112. , And each step 110-112 is repeated each time a character is input in this way. If it is determined in step 111 that the mode is not the registration mode, it is processed as a normal text input. After that, when the execution key 14 is operated, the step 12
Operations after 0 are performed. In step 122, it is judged whether or not there is data in the keyword buffer 42. There is data in the keyword buffer 42 now,
Therefore, in order to add the keyword name and perform the storage registration, the process proceeds to step 150 in FIG. The content TEXT of the store area 71 is stored in step 150 as the content STEXT of the buffer 44. That is, the start address of the newly registered area of the registration area 75 is stored as the content STEXT of the buffer 44. Subsequently, the above steps 133, 134, 1
In the same way as in step 35, in step 151, the sentence buffer 4
The number of bytes of the registration text of 1 is the content of the buffer 45 TEXTB
In step 152, the contents STEXT of the buffer 44 and the contents TEXTBYT of the buffer 46 are added and stored as the contents STEXT of the buffer 44, and the final address n of the memory 7 is compared with the step 153.

Now, assume that the temporary registration area of the memory 7 is not yet formed. That is, the content of the store area 72 is blank. Therefore, step 154
To step 155, the contents TE of the store area 71
XT is transferred to pointer 48. After that, the same operations as in steps 137 to 141 are performed in steps 156 to 160, and the registered sentence of the sentence buffer 41 is transferred to the registration area 75 and stored therein. By such an operation, the content STEXT of the buffer 44 stores the start address of the area to be registered next in step 152, and the content STMP of the buffer 43 is blank (Nul in the initial state).
l).

Then, in step 161, a new head address value to be stored in the keyword table 74 stored in the index area 73 of the memory 7 is read out and the corresponding address in the keyword table 74 is selected. In step 162, the keyword data is stored in the keyword buffer 42 in order from the selected position in the keyword table 74. In step 163, following this data, the content TEXT of the store area 71, that is, the start address of the registered area 75 of the sentence just registered is transferred to and stored in the keyword table 74. Next, the address value of the next store area of the keyword table 74 is stored in the index area 73 and updated in step 164. After that, the contents TEXT of the store area 71 is changed to the registration area 7 by the operations of the above-mentioned steps 142 and 143.
5 next address value, ie the contents ST of buffer 44
EXT is stored, and the contents of the store area 72 remain blank and do not change.

The registration operation when the temporary registration area is formed in the registration area 75 at the time of the determination in step 154 will be described. Now, assume that the details of the stored state of the memory 7 are as shown in FIG. 5 (1). The content TEXT of the store area 71 is the start address An of the new registration area 75, and the content TMP of the store area 72 is the start address Am of the temporary registration area. The contents AI are stored in the index area 73. Before the temporary registration, the text of the keyword name "XYZ" is stored as the head address A 1, the keyword table "XYZA" is stored, and the next address AI is stored in the index area 73.

Referring to FIG. 4, steps 154 to 170
Move on to. The content STEXT of the buffer 44 is shown in Fig. 5 (2).
The address Aq indicated by is stored. In this step 170, the address value for one character is subtracted from the content STEXT, and (Aq-1) becomes the address pointer 4
9 content AP2 is stored. At step 171, the number of bytes of the text to be temporarily registered to be stored at the head address of the text to be temporarily registered is read and stored as the content TMPBYT of the buffer 45. In step 172, the address value obtained by subtracting one character from the content TEXT of the store area 71, that is, (An-1).
Is stored as the content AP1 of the pointer 48. At step 173, the content K of the counter 47 is reset, then steps 174 to 177 are executed, and the texts "byte number data" and "Japanese ... ai" to be temporarily registered are set to the lower address with the address (Aq-1) as the final address. Be moved to. More specifically, the contents of the counter 47 are incremented by 1 in step 174, and
5, the data in the registration area 75 corresponding to the position of the content AP1 of the pointer 48 is read and the content A of the pointer 49 is read.
Transfer to the address position (Aq-1) represented by P2. At step 176, it is judged whether the content K of the counter 47 is equal to the content TMPBYT of the buffer 45, that is, the number of bytes of the temporary registration text. If they are not equal, at step 177, the contents AP1 of the pointers 48 and 49, AP1.
AP2 is reduced by one character each. By repeating the operations of steps 174 to 177,
The content AP1 of the pointer 48 changes to An-1, An-2, ... And the content AP2 of the pointer 49 changes Aq-1, Aq-.
It changes with 2, ...

When the content K of the counter 47 becomes equal to the content of the buffer 45 in step 176, the process moves to step 178 and the address data indicated by the content AP2 of the pointer 49 is stored as the content STMP of the buffer 43. That is, the address AR shown in FIG. 5 (2) is the buffer 4
3 will be stored. After that, in step 179, the contents TMP of the store area 72, that is, the address A
m is transferred as the content AP1 of the pointer 48. Then, by executing steps 180 to 184, the same operation as in steps 137 to 141 described above is performed, and the registered sentence of the sentence buffer 41 is sequentially stored in the registration area 75 as the head address Am. Step 1
When the content K of the counter 47 matches the content TEXTBYT of the buffer 46 at 83, the process moves to step 161, the content TEXT of the store area 71 is stored as the content value Aq, the content TMP of the store area 72 becomes AR, and the index area The content of 73 is updated to Aj,
As a result, the store state as shown in FIG. 5 (2) is achieved. In this way, the temporary registration area is always formed in a blank area, and the memory 7 can be used with high efficiency.

The present invention can be implemented not only in the context of a document processing device, but also in other data processing devices that process data other than text data.

Further, in the present invention, a memory having another configuration may be used instead of the random access memory 4, and a memory having another configuration may be used instead of the non-volatile memory 7.

As described above, according to the present invention, the created text data can be temporarily registered in a memory such as a floppy disk. Particularly, the temporary registration data is stored as a plurality of registration data with keywords. In addition to the second store area that manages the storage address of the keyword-added registration data in order to store the temporary registration data uniquely in the first store area, which is the same as the first store area, Since a third store area is provided for storing and managing the new storage address by replacing the old storage address each time the temporary registration data is stored, fixed temporary registration for temporary registration control of data such as text. Since the temporary registration control can be performed without providing a region, there is an effect that the temporary registration control of the data such as text is efficiently performed.
