Abstract

PURPOSE:To suppress a cost to keep information by keeping information with few information amount and a large number of times of access in a first external storage means capable of performing fast response, and the information with a large information amount and few number of times of access in a second external storage means with low responsiveness out of input information separately. CONSTITUTION:Inputted information is stored once in an internal storage means 3. When a control means 1 keeps the information stored in the internal storage means 3, the information is divided into the information with comparatively few in keeping capacity and with the large number of times of access, and the one with comparatively large in keeping capacity and with the few number of times of access, and the former is written on an kept in the first external storage means 4, and the latter in the second storage means 5. When kept information is read out, the readout control of the information kept in the external storage means 4 and 5 are performed corresponding to a processing purpose. In such a way, it is possible to form an information generation memory device with high working efficiency and a profitable cost.

Description

[Detailed Description of the Invention] A. Industrial Application Field This invention stores input information in an external storage means,
The present invention relates to an information creation device that writes and reads input information according to a processing purpose, and particularly relates to a technique for controlling writing and reading to and from external storage means.

B. Prior Art Conventionally, this type of information creation storage device stores, for example, document information (including layout, character 1 figure 5 image information).
an input section for inputting information, a processing section for digitally processing this information, an external storage section for storing a large amount of document information processed by the processing section, a display section for displaying the document information on a screen, etc. There are some that are equipped with.

According to the above device, when document information is input using a keyboard or an image scanner as an input section, the processing section converts the layout of the document information.

Character 1 graphic information is encoded, image information is converted to don't data, and if necessary, CI? Document information is displayed on the screen of a display unit such as T.

When storing the input document information, the processed document information is written to a magnetic disk or optical disk as an external storage connected to the processing section. At this time,
- The entire amount of document information was stored in one document file in the external storage unit.

When processing stored document information such as modification 2 display, printing, etc., the processing section specifies the relevant document file in the external storage section, thereby reading out -the amount of document information.

Problems to be Solved by the C0 Invention However, the above-mentioned conventional device has the following problems.

Of the document information, the layout, text, and graphics information are encoded, so the storage capacity required for storage is relatively small, but image information is don't data, so
Requires large capacity for storage.

Furthermore, since layouts, text, and graphic information are artificially created, they are often subject to frequent revisions; however, image information such as photographs and graph waveforms is a representation of reality, so revisions are not required. It is extremely rare that this is necessary.

A layout with such properties, character 1 graphic information,
If image information is stored all at once in an external storage unit such as a magnetic disk capable of high-speed response, work efficiency can be improved by shortening the access time, but high-speed response is relatively expensive. Since it is necessary to construct an external storage unit with a large capacity, a problem arises in that the cost is high.

In addition, when storing data on a relatively inexpensive external storage device with slow response speed, such as an optical disk, the cost can be lowered compared to a magnetic disk, but the access time becomes longer.
A problem arises in that work efficiency is reduced.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an information creation/storage device that has high working efficiency and is advantageous in terms of cost.

01 Means for Solving the Problems The present invention has the following configuration to achieve the above object.

That is, the information creation device according to the present invention includes a first external storage means with a relatively fast response, a second external storage means with a relatively slow response, and a second external storage means that temporarily stores input information. Among the input information stored in this internal storage, information that has a relatively small amount of information and is accessed frequently is stored in the first external storage. The present invention is characterized in that it stores information that is large in volume and accessed infrequently in the second external storage means, and further comprises a control means for accessing each of the external storage means according to the purpose of processing the input information.

81 Effects According to the present invention, input information is temporarily stored in the internal storage means. When the control means stores information stored in the internal storage means, it divides the information into information that has a relatively small storage capacity and is accessed frequently, and information that has a relatively large storage capacity and is accessed few times, and divides the former into information that has a relatively large storage capacity and is accessed few times. The latter is written and stored in one external storage means and the second external storage means. When reading the stored information, the reading of the information stored in each external storage means is controlled depending on the processing purpose. For example, when only modifying characters in document information that includes image information, only the information in the first external storage device can be read out at high speed by not reading out the second external storage device. The data is temporarily stored in the internal storage means and required processing is performed.

F. Example Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram schematically showing the configuration of a document creation storage device according to an embodiment of the present invention.

In the figure, the symbol l indicates the digital processing of input document information,
A CPU serves as a control means for controlling writing and reading of document information; 2 is a flag register for registering the state of a flag that instructs handling when reading document information; 3 is an internal storage means for temporarily storing document information; buffer memory.

These mainly constitute the microcomputer main body 10.

The buffer memory 3 is an internal memory that has the same operating speed as a relatively high-speed magnetic disk, and has a capacity sufficient to store document information. In this case, the document information includes the document header and layout.

It consists of characters, 2 figures, and image information. The document header is made up of - a document file name of a file that stores document information, and an information pointer that is information on each addressing area in which layout, character, figure, and image information are stored, respectively.

The reference numeral 4 designates a magnetic disk provided outside the microcomputer main body IO and serves as a first external storage means for storing a large amount of document information, and the reference numeral 5 designates an optical disk as a second external storage means. The magnetic disk 4 stores document file names, layouts,
The optical disk 5 is arranged for the purpose of storing character 5 graphic information and information pointers thereof, document file names, image information, and image information pointers.

Reference numeral 7 is an image scanner as an input device for document information, and 8 is a keyboard also as an input device. The image scanner 7 reads input image information and transmits it to the microcomputer main body 10, and the keyboard 8 is configured to input layout and character 1 graphic information by key operations.

Reference numeral 6 indicates a printer as an output device, and 9 indicates a CRT, which also serves as an output device.The printer 6 is configured to print document information, and the CRT 9 is configured to display the document information on its screen.

Next, the operation of the above-described embodiment apparatus will be explained based on the flowchart of FIG.

(1) Write operation (see FIG. 2(a)) Step S1
At step S2, the CPUI reads the document header in the buffer memory 3 and writes it in the buffer memory 3 by adding a document header to each piece of information input using the keyboard 8 or image scanner 7. ,letter.

Each piece of information in the address area where graphic information is stored is transmitted to the magnetic disk 4 along with the document file name and each information pointer. Further, the information in the address area where the image information is stored is transmitted to the optical disc 5 along with the document file name and the image information pointer.

As described above, one piece of document information that is input one after another is sorted and stored on the magnetic disk 4 and the optical disk 5.

(2) Reading operation (see Figure 2)) First, when the name of the document file to be read is designated via the keyboard 8, the reading operation is started. In step Nl, the CPU
I reads the state of flag register 2.

When specifying document information, the operator specifies whether it is necessary to read a piece of document information including image information. When one document information including image information is specified, a flag "l" is set in the flag register 2. When one document information that does not include image information is specified, the flag in the flag register 2 is set to "0".

In step N2, the state of the flag register 2 is determined, and if the flag register 2 stores "1", the process moves from step N2 to step N3.

In step N3, the CPU reads the document header with the specified document file name from the magnetic disk 4 and the optical disk 5, specifies the address area registered in each information pointer, and transfers the layout character 5 graphic information to the magnetic disk. By transmitting the image information from the optical disk 5 to the buffer memory 3 and the image information from the optical disk 5 to the buffer memory 3, all document information is read out.

In step N5, processing such as displaying and printing the document information stored in the buffer memory 3 is performed. At this time, based on the layout information stored in the buffer memory 3, the layout of the characters 9 and the image information is performed.

If it is determined in step N2 that the flag register 2 stores "0", steps N2 to N4
Move to.

In step N4, the CPU 1 reads the document header with the specified document file name from the magnetic disk 4,
The address area registered in each information pointer is designated, and the layout and character 1 graphic information are transmitted from the magnetic disk 4 to the buffer memory 3. At this time, reading from the optical disc 5 is not performed.

In step N6, the document information stored in the buffer memory 3 is displayed, and modifications and the like of the document information are performed.

At this time, the characters based on the layout information.

The graphic information is arranged, and the area where the image information is stored is displayed as an empty frame. The revised document information is stored on the magnetic disk 4 again.

In this way, among the input document information, the layout, character and graphic information are stored on the magnetic disk 4, and the image information is stored on the optical disk 5. When modifying the document information other than the image information, When the magnetic disk 4 is accessed at high speed and one document information including image information is displayed or printed, the magnetic disk 4 and
One document information is read from the optical disc 5.

In the above-described embodiments, a magnetic disk was used as the first external storage means with high-speed response, and an optical disk was used as the second external storage means with low-speed response, but the present invention is not limited to these storage media. Needless to say.

Furthermore, although the embodiments have been described using document information as an example, the present invention can also be applied to other information as long as it is possible to distinguish between large amounts of information that is rarely modified and information that is small and frequently modified.

Effects of the G3 Invention As is clear from the above explanation, the information creation and storage device according to the present invention uses a first external storage means that can quickly respond to input information that has a relatively small amount of information and is accessed frequently. In addition, a large amount of information can be stored by distributing it to the second external memory ↑ and α means with slow response, which can obtain information with a relatively large amount of information and a small number of accesses at a relatively low cost. In doing so, costs can be reduced compared to storing only in expensive high-speed response storage means.

In addition, when reading information, for example, for processing purposes such as modifying document information, reading from the second external storage means is prohibited and only the first external storage means is accessed, making it possible to reduce costs. Compared to the case where information is stored only in a slow-response storage means, access time can be shortened and work efficiency can be improved.
