Abstract

PURPOSE:To provide a terminal which has no PF key with the same functions with PF keys by holding a key code generated in key operation from the 1st function key to the 2nd function key as retrieval information and outputting the 3rd specific code characteristic to the retrieval information. CONSTITUTION:A code string buffer 14 which enables PF key substitute input operation is stored with respective key input codes between the operations of the 1st and the 2nd specific keys provided to an input part 11 in the order of key input. The 1st specific key is defined as a (can) key and the 2nd specific key is defined as (return) key; and respective key codes between (can) key operation to (return) key operation are stored. For example, key codes are so outputted that (can)+(1)+(return) correspond to (PF1).

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an input control method for connecting a plurality of types of terminal equipment with different function selection mechanisms [L] [L] [Technical field of the invention] .

[Prior art and its problems] In a system that can connect multiple types of terminals, usually
A table (file) defining the functions of each terminal to be connected is prepared, and an application program is programmed to refer to this table and perform processing that matches the functions of the connected terminal.

Conventionally, when making the application program described in 2 above operable on both a terminal equipped with a PF primary key (programmable function key) and a terminal without a PF primary key, it was necessary to Possible methods include creating a program that does not use the PF primary key, and creating a program that operates by referring to the function table of each terminal.

However, these methods have the following problems.

That is, in order to create a program that does not use a PF primary key to suit a terminal that does not have a PF primary key, it is necessary to create a new program that does not use a PF primary key.
This causes the inconvenience that the functions of the terminal having the F primary key cannot be used effectively.

Also, if you want to take advantage of the functions of a terminal with a PF primary key by referring to the function table of each terminal, you will need to perform both the logic when there is a PF primary key and the logic when there is no PF primary key. There is an inconvenience that the program has to be prepared and the amount of programs increases.

[Purpose of the Invention] The present invention enables alternative input to the specific function keys on a terminal that does not have specific function keys, such as PF primary key programmable function keys, without changing the functional configuration of the terminal. In this way, the same specific function key of a terminal that does not have the above-mentioned specific function key can be changed manually using an intermediate and inexpensive configuration without requiring any hardware changes to the terminal or causing an increase in the amount of application programs. The purpose of the present invention is to provide an input control method that makes it possible to perform function selection.

[Summary of the Invention 1 The present invention holds key codes associated with key operations from the first specific function key operation to the second specific function key operation of the input mechanism, and uses the held key codes as search information. The method includes means for outputting a third specific key code unique to the search information from a conversion table prepared in advance, so that the input mechanism does not receive key input information in combination with a preset specific key. It has a configuration that outputs the key code of the function key, so that, for example, on a terminal without a PF primary key, PF primary key alternative input can be performed without changing the functions of the terminal, and the PF primary key function is lost. It is possible to reduce the amount of application programs without having to do so.

[Embodiment] (1), Configuration FIG. 1 is a block diagram showing the configuration of essential parts in an embodiment of the present invention.

In FIG. 1, 11 is an input section such as a keyboard unit without a group of keys, and 12 is a code buffer that temporarily stores key codes input by key operations on the input section 11. 13 is an input control circuit for manually controlling the keys of the input section 11;
Performs key manual determination processing for key manual codes stored in .

14 is a code string buffer for enabling PF primary key alternative input;
The manual codes for each key from the first specific key operation to the second specific key operation are stored in the order of key input, and here,
The first specific key is the [Can] key, the second specific key is the [r8tUrn] key, and the manual codes for each key from the operation of the [can] key to the operation of the [return] key are stored.

15 is a code conversion table for converting the code information stored in the code string buffer 14 into a PF primary key code that is not stored in the input section 11;
r e t ur n, ] With key human power,
A search is made based on the code information stored in the code string buffer 14, and a PF key code unique to the information is output.

FIG. 2 is a diagram showing examples of various PF primary key alternative input key codes in the above embodiment, and here, [Can] + [1

PF9] output the key code, and press [Can] + [C]
+[0]+cpl+[Y]+[returnl key] Outputs the [PFn] key code manually.

(2) 1 When a key is operated on the action input unit 11, a key code unique to that operated key is stored in the code buffer 12.

The input control circuit 13 determines the contents of the key code stored in the code buffer 12, and if the code is not the key code of the [can] key indicating input of a PF primary key alternative code, the code is stored in the code buffer 12. The generated key code is output to a processing device as it is as key manual data.

Further, when the key code stored in the code buffer 12 is the key code of the [can] key indicating input of the PF primary key alternative code, the input control circuit 13 enables the code string buffer 14 and inputs the [can] key code. The key codes stored in the code buffer 12 by key operations after the key are stored in the code string buffer 14 in the order of input.

Thereafter, the key code associated with the operation of the [return] key is stored in the code buffer 12 5, and when the same code is discriminated by the input control circuit 13, the input control circuit 13 inputs the code stored in the code string buffer 14. Based on the information, a PF main key unique to the code information is obtained by referring to the code variation m chifur 15, and the code is output as key manual data. Furthermore, at this time, the input control circuit 13 clears the code string buffer 14 upon completion of the search for the PF main key, and selects the next j['can]
Prepare for PF primary key alternative key manual labor associated with key operations.

Specific examples of various PF primary key alternative input key codes at this time are shown in FIG. Here, [CanJ+[1]+

The [PFn] key code is output by manual operation of the [rn] key.

In this way, [, can] key and [return
] The code conversion table 15 is searched based on the contents of the key manual code stored in the code string buffer 14, which is specified by the key, and a PF primary key code specific to the key manual code is generated. With this configuration, even in terminals that do not have a PF primary key, PF primary key alternative input is possible without changing the terminal mechanism. Therefore, without changing the function (hardware) of the terminal, PF
A system with a primary key selection function can be constructed at low cost.

Furthermore, there is no need to change the logic depending on the presence or absence of the PF primary key on the terminal side, and the program time of the application program can be reduced.

Note that the code conversion table 15 in the above embodiment is RO
It may be configured with M or RAM. Furthermore, although the above embodiment has been explained using the PF primary key alternative input as an example, it can also be applied to other alternative key manual inputs.

[Effects of the Invention] As detailed above, according to the input control method of the present invention, the key code associated with the key operation between the first specific function key operation and the second specific function key operation of the input mechanism is controlled. The stored key code is used as search information to output a third specific key code specific to the search information from a pre-prepared conversion table, so that the key code can be combined with a preset specific key. By having a configuration that outputs the key of the function key that the input mechanism does not have from the key input information by matching, for example, on a terminal that does not have a PF primary key, it is possible to input the PF primary key without changing the function of the terminal. Alternative input can be performed, and the amount of application programs can be reduced without impairing the PF primary key function.
