Abstract

PURPOSE:To reduce a time loss by eliminating unnecessary access to a main frame by an external request through the logic of a terminal equipment in consideration of the frequencies of use of previously registered character patterns. CONSTITUTION:When an area code with a registration number (k) and its pattern are used in the terminal, a microprocessor 28 alters the deletion order of a deletion register 25 and a chain memory 26. Namely, a location corresponding to contents LAST is retrieved in the chain memory 26 and the contents are changed from (l) to LAST to put the registration number (k) at the lowest position of the deletion order. Then, a location where the contents (k) are stored is retrieved in the deletion register 25 and chain memory 26 and the contents are changed from (k) to (l). This operation carries out the maintenance of the deletion order every time a previously registered external character pattern is used.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an external character management system for a terminal device that takes frequency of use into consideration.

[Technical background of the invention and its problems]

In 11 computer systems capable of processing kanji, kanji patterns are often registered in advance in an internal buffer of a terminal device. Normally, the first level kanji no f turn is stored in the internal ROM of the terminal, and the second level kanji and special character patterns are stored in the external character RAM. However, external character RAM
The number of external characters that can be registered is limited due to capacity.
It is usually about 100 characters.・To register 9 turns, when the corresponding code required by the terminal is not in the external character RAM, a request for external character/mother turn is made to the main unit (AT'rU; attention).
This is done by issuing a procedure. (See Figure 1) By the way, when registering new patterns in excess of the number that can be registered, it is necessary to delete the already registered patterns.

A common method for erasing a pattern is to manage the external character RAM in a cyclic manner and erase the oldest registered pattern in terms of time. According to this method, the frequency of use of the pattern is not taken into account, so even if the pattern is frequently used, if the registration is old, it will be deleted. For this reason, after deletion, it is not necessary to issue a turn request again when necessary, resulting in a large loss of time.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned drawbacks, and by considering the frequency of use of registered character patterns in a relatively simple manner, unnecessary access to the main body due to a request for a custom character pattern can be eliminated. The purpose of this invention is to provide a system for managing external characters in a terminal device that reduces time loss.

[Summary of the invention]

In order to achieve the above object, the present invention is characterized in that each time a registered pattern is used, the deletion order is maintained so that the registered pattern is placed at the lowest position in the deletion order. Therefore, in the present invention,
Next, there is a register in which the registration number of the custom character pattern to be deleted is set, a chain memory in which the registration number is set in order of frequency for deletion, and a location where the special code is stored by referring to this chain memory. Search, change the contents to the registered number of the currently used external character/zo turn, and at the same time change the contents of the chain memory corresponding to the changed number to a special code, and delete the currently used registered pattern to the bottom of the deletion order. A microprocessor to be located was prepared.

This eliminates the needless request for 9 turns of characters that requires access to the main body, thereby reducing time loss.

[Embodiments of the invention]

Hereinafter, the present invention will be explained in detail using the drawings.

Figure 1 shows the external character Z issued from the terminal device to the main body.
FIG. 3 is a diagram showing a turn request procedure.

That is, a pattern search is performed in the external character RAM (shaded area in the figure) in the terminal device 3, and the desired character/character is searched here.
If it is confirmed that there is no such turn, a custom character zo turn request (ATTN) is issued. Upon receiving this request, the main body 1 generates the corresponding pattern and sends it to the terminal device (TR).

The terminal device 2 registers the turn in the external character RAM (hatched block in the figure).

FIG. 2 is a block diagram showing an embodiment of a terminal device in which the present invention is implemented. In the figure, 21 is an area indicating a private character registration number, and if the number of registerable characters in the private character RAM is N, then a value of 0.1° . . . (N-1) can be obtained as a serial number. 22 and 23 are code memories 24 for storing the codes of the wards and dots of the private characters for each private character registration number;
is a buffer that stores the external character pattern corresponding to the 1-point code. Reference numeral 25 designates a register indicating the next non-standard character registration number to be deleted when the registration of the non-standard character RAM becomes full, and 26 is a chain memory for managing the priority order of deletion. 27 is a counter indicating the number of external characters registered in the external character RAM. 28 is a memory group in which the microprocessor for managing each buffer memory shown in 21 to 27 above and its program are stored.

Hereinafter, for the sake of simplicity, this block 28 will be simply referred to as a microprocessor.

3, 4, and 5 are operational conceptual diagrams showing the operation of the present invention expanded on the memory, and FIG. 3 shows the register 25.
And the initial setting state of the chain memory 26 is shown in FIG.
FIG. 5 is a diagram illustrating the recombination operation on the chain memory 26 taking into account the lean frequency, and the process of erasing and registering a new custom character/turn when the custom character RAM is full.

The operation of the present invention will be described in detail below.

Assuming that the number of characters that can be registered in the private character RAM is N, when the private character registration counter 27 is smaller than N, there is an empty area, so new private character codes and patterns can be stored in each buffer memory 2.
The contents of 1 to 24 are registered while being incremented sequentially.

When the non-standard character registration counter 27 becomes equal to N, it is necessary to delete the registered pattern and register a new pattern. First, the contents of the erase register 25 and chain memory 26 are
Initial settings are made as shown in the figure. The contents of the deletion register 25 and the chain memory 26 are higher as the non-registered character registration number is smaller.

One point, one C'tan, will be erased.

LAST means the final ranking, so a special code can be assigned to it.

Here, when the code and its pattern are used in the terminal, the microprocessor 28 changes the erasure order in the erasure register 25 and the chain memory 26, as shown in FIG. is carried out, i.e.
First, the chain memory 26 is searched for the location where the content Li5t is stored, and the content is changed from t to 1ist.

This places the private character registration number K at the bottom of the deletion order. Next, the erase register 25 and chain memory 26 are searched for the location where the content K is stored, and the content is replaced with 1+t. Through the above-described operation, maintenance for deletion 11n is performed every time a registered external character pattern is used. That is, when the registered 24 turns are used, the rosock moves its deletion order to the lowest, making it possible to hold frequently used patterns so that they are difficult to delete.

Figure 5 shows how to delete a custom character pattern and create a new pattern as a custom character.
It is a diagram showing the state of registration after the turn request procedure. At this time, the ward, point 1, which corresponds to the private character registration number indicated by the contents of the deletion number register 25, is selected. ．． , 6 turn buffer 22
, 23. Replace the contents of 24. Deletion number register 2
The content of item 5 is convenient for maintenance, since the infrequently used custom character registration number is referenced, and as a result, unnecessary procedures for requesting custom characters and 9 turns can be reduced.

〔Effect of the invention〕

As explained above, according to the present invention, unnecessary character pattern requests that require access to the main body can be eliminated by managing the custom characters in consideration of the frequency of use of registered characters, zo, and turns inside the terminal. Time loss can be reduced.
