Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a kanji processing system using a kanji processing device that stores pattern images of kanji and the like.

In addition to a kanji processing device that displays characters and symbols such as kanji, katakana, and alphanumeric characters on a cathode ray tube or paper, a kanji processing system requires a pattern storage unit that stores these characters and symbols. Conventionally, the pattern storage section has been provided individually in each of the kanji processing devices, or provided in common among several kanji processing devices. The former type can be further divided into those in which each kanji processing device, such as a kanji display device, has a built-in pattern storage section, and those in which each device is connected to a dedicated pattern storage section.

By the way, the type in which each kanji processing device is provided with a separate pattern storage section has the advantage that each terminal (kanji processing device) can independently process characters such as kanji even when offline. However, in this case, since the pattern storage section had to individually store a huge number of character patterns, each kanji processing device had the disadvantage of inevitably being expensive and large. In addition, the above-mentioned disadvantage does not exist in a type in which several kanji processing devices share a pattern storage section, but since each kanji processing device does not have its own pattern storage section, each terminal can perform its own kanji processing when offline. The drawback was that it could not be done.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a kanji processing system that can process kanji at a normal level without increasing the size of each kanji processing device. The present invention provides a kanji processing system that accesses a pattern storage unit that stores character patterns and supplies desired character data to a plurality of kanji processing devices, in which the character patterns are classified into blocks according to the usage frequency of each kanji processing device. and supplying the first frequently used block to a dedicated and accessible internal pattern storage provided in each kanji processing device,
The present invention is characterized in that the other second blocks are supplied to an external pattern storage section that can be accessed in common by all of the kanji processing devices based on priority order. achieve this objective.

The present invention will be explained in detail with reference to Examples below.

In FIG. 1, which shows the layout of the pattern storage units, the two kanji display devices 1 and 2 and the two kanji printers 3 and 4 are kanji processing devices located in the same business. It is connected to an external pattern storage device 5 located at a location by data lines 6 to 9. Each of the kanji processing devices 1 to 4 has a built-in pattern storage unit (not shown) that stores character patterns (hereinafter referred to as first block character patterns) that are often used in the respective devices. For example, the pattern storage section in the first Kanji display device 1 and the first Kanji printer 3, which are used for general purposes, stores 2304 characters that frequently appear on newspaper pages.
These 2304 characters are classified as internal characters of the CO-59 code used in the press, and there are 90 characters such as normal kanji written in newspapers etc.
It has an appearance rate of several percent. In addition, the pattern storage section built into the second kanji display device 2 and kanji printer 4 used in science and technology fields contains special kanji characters used as technical terms,
Character patterns for Greek words, symbols, etc. are stored together with general character patterns.

On the other hand, the external pattern storage section 5 has a second
Each kanji processing device 1 is used as a block character pattern.
External characters for ~4 are stored. In other words, tens of thousands of character patterns, including even kanji characters that appear very infrequently, are stored on storage media such as magnetic disks.

FIG. 2 is for explaining the kanji processing operations of these kanji processing devices and external pattern storage devices.

The first kanji display device 1 includes an input section 1
1, control section 12, pattern block switching section 13,
It is composed of an internal pattern storage section 14 and an output section 15. Second kanji display device 2
Similarly, it is composed of an input section 21, a control section 22, a pattern block switching section 23, an internal pattern storage section 24, and an output section 25. The first kanji printer 3 and the second kanji printer 4 have exactly the same configuration, so illustration thereof will be omitted. Further, the description will focus on the first kanji display device 1 to avoid duplication.

Now, the input unit 11 in the first kanji display device 1 is connected to kanji input devices such as a paper tape reader and a card reader, and a central processing unit, and the CO-59 code (hereinafter input code) supplied from these devices is ) will be received. The input code is
The internal characters of the 2304 characters are represented by 6-bit double codes, and the external characters are represented by 7- or 8-bit double codes including external character identification bits. The input code received by the pattern block switching unit 13 is sent to the control unit 12 in order to display a predetermined display on a CRT (cathode ray tube).
, and receives switching control regarding the supply destination. That is, among the input codes sequentially supplied to the pattern block switching unit 13, the input codes related to the character pattern of the first block corresponding to internal characters are supplied to the internal pattern storage unit 14, and the kanji corresponding to the supplied input code is supplied to the internal pattern storage unit 14. Character patterns such as the following are selected. The character data regarding the selected character patterns are then sequentially supplied to the output section 15.

On the other hand, among the input codes supplied to the pattern block switching section 13, input codes corresponding to external characters are supplied to the external pattern storage device 5 through the data line 6A. The external pattern storage device 5 has code input sections 51, 52 and pattern output sections 53, 5 provided as many as the number of connected kanji processing devices.
4, and one external pattern storage section 55. The data line 6A is connected to a first code input section 51 provided corresponding to the first kanji display device, and the supplied input code is supplied to the external pattern storage section 55 via the code input section 51. Ru. The external pattern storage unit 55 selects character patterns such as kanji characters that correspond to the supplied input code, and outputs character data regarding the selected character patterns to a pattern output unit provided corresponding to the first kanji display device 1. 53. The pattern output section 53 supplies the supplied character data to the output section 15 of the first kanji display device through the data line 6B.

The output section 15 performs output processing on the character data supplied from both the internal pattern storage section 14 and the external pattern storage section 55 in accordance with the control operation of the control section 12 . As a result, predetermined characters or sentences are displayed on the CRT in the output unit 1.

Incidentally, there are cases where the two Kanji display devices 1 and 2 access the external pattern storage device at approximately the same time. In this case, the external pattern storage section 5
5 preferentially handles the kanji display device supplied first to the code input units 51 and 52, and first supplies character data to that kanji display device.
Furthermore, a priority order is determined in advance among the kanji display devices, and processing is performed so that character data is supplied in order from the kanji display device with the highest priority. Note that when a large number of kanji processing devices are connected to an external pattern storage device, the sum of the processing speeds required by the individual terminal devices may temporarily exceed the processing speed of the external pattern storage device. If there is such a possibility, for example, the output section of each kanji processing device may be provided with a buffer memory of sufficient capacity to absorb fluctuations in the amount of input character data.

In this way, according to the present invention, there is no need to separately store character patterns for many types of kanji and special symbols that are used infrequently for each kanji processing device, so the overall cost is low and the reproducibility is good. A kanji processing system can be realized. In addition, each kanji processing device has built-in or proprietary character patterns for character types that are used relatively frequently, so if the external pattern storage device is not operating due to a malfunction or the like, or if the external pattern storage device is
Even when connected to the CPU side and offline,
By replacing special characters with hiragana, etc., and outputting them, it is possible to ensure normal usage. Therefore, the present invention is extremely effective for processing kanji in fields where time is limited, such as in the news industry.
Furthermore, if the pattern storage section is divided into a plurality of blocks according to the frequency of use as in the present invention, for example, for customers who only need a small number of character types, a terminal device that accommodates only the pattern storage section of the first block can be used. For customers who require a large number of character types, it is possible to provide a system in combination with an external pattern storage device as in the present invention. Therefore, it is possible to standardize the individual devices in the kanji processing system, and in this respect, it is also possible to reduce the cost of the system.

Furthermore, character patterns of the second block (other than those that are frequently used) are stored in the external pattern storage unit, and the kanji processing device accesses them based on priority order, so that multiple kanji characters can be accessed at the same time. Even if the data is generated from the processing device, accurate access can be guaranteed.
