Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a keyboard input processing device that outputs data corresponding to operated keys on a keyboard.

[Conventional technology]

This type of device has a map in which data corresponding to each key on the keyboard is registered, and when a key on the keyboard is operated, the data of the map corresponding to that key is output, which is a process called mapping. The data obtained is passed to the program that requires the data. That is, it is for inputting data corresponding to a key to a program in response to a key operation on the keyboard.

However, conventional devices generally have only one map, so if you want to change the format of data passed to a program, for example, you have to change the map that corresponds to the keyboard, or Two-step mapping was performed in which other maps were included in the program and data was obtained from the other maps included in the program in response to each data from the map corresponding to the keyboard. Furthermore, even when the type of keyboard is replaced, it is necessary to change the map corresponding to the keyboard or to include another map corresponding to the map in the program to perform two-step mapping.

[Problem to be solved by the invention]

In this way, conventional keyboard input processing devices have only one map, so if you want to change the format of data passed to a program or replace the type of keyboard, you need to change the map or use two maps. It was necessary to perform two-stage mapping based on the above information, resulting in complicated work and double processing.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a keyboard input processing VJI that allows data in a required format to be easily obtained regardless of changes in data format or type of keyboard.

[Means for Solving the Problems] The present invention includes a memory that stores a plurality of types of maps in which data corresponding to each key of a keyboard is registered, and one of the maps stored in the memory. It is characterized by comprising a selection means for making a selection according to a request from a program or the type of keyboard, and a mapping means for reading and outputting data corresponding to a key operated on the keyboard from a map selected by the selection means. shall be.

[Operation] According to the present invention, when one of the maps in the memory is selected by the selection means, data corresponding to the key operated at the time of keyboard operation is read from the selected map. is output.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram schematically showing a first embodiment of a keyboard input processing device according to the present invention.

In the figure, an event input device 1 is a keyboard provided with a plurality of keys, each of which is given an input code in advance.

When any one of the keys is pressed, the input code corresponding to the pressed key is transmitted to the mapping means 2 as event data.

The map storage memory 3 stores a plurality of maps M-1 to Mn, and each output corresponding to each key of the event input device 1 is registered in each of these maps M-1 to Mn. . The map selection means 4 selects one of the maps M-1 to M-1 in the map storage memory 3.

Here, when any key on the event input device 1 is pressed, the input code corresponding to the pressed key is transmitted to the mapping means 2.

When the input code is input, the mapping means 2 accesses, through the map selection means 4, the map in the map storage memory 3 selected by the map selection means 4. For example, when the map M-1 is selected by the map selection means 4, the mapping means 2 selects the event input device 1.
The output code specified by the input code from the map M-1 is read from the map M-1, and this output code is sent to the program 5.
pass it on to Therefore, the output code corresponding to the pressed key on the event input device 1 is read from the map M-1, and this output code is passed to the program 5.

FIG. 2 is a block diagram showing details of the first embodiment shown in FIG. 1. Here, map M-1 and map M-2 are each registered in advance in the map storage memory 3, output codes are sequentially stored in map IVL-1 from the start address MAP10, and map M-2 is Output codes are sequentially stored starting from the first address MAR20. The keyboard 11 corresponds to the event input device 1 shown in FIG. 1, and the keyboard 11 is provided with keys 12 assigned respective input codes. For example, key 12a has an input code "12".
” is given.

Next, the operation of this embodiment will be described according to the flowchart shown in FIG.

First, the map selection means 4 checks whether any map in the map storage memory 3 is to be selected (third
Step 101 in figure (a)). And, for example, Mappu M

Start address MAP of map M-1 selected during this time
10 is stored in the memory area 40 in the map selection means 4 (step 103 in FIG. 3(a)). Thereafter, the map selection means 4 allows event data to be passed from the keyboard 11 to the mapping means 2 (step 104 in FIG. 3(a)).

On the other hand, if the event data passing is permitted in step 104, the mapping means 2 specially inputs the event data from the keyboard 11 (each step 201, 202 in FIG. 3(b)). Here, For example, when a key 12a is pressed on the keyboard 11, the input code "12" corresponding to the key 12a is transmitted from the keyboard 11 to the mapping means 2 as event data.

The mapping means 2 accesses the map storage memory 3 through the mapping selection means 4 based on this input code "12". That is, the mapping means 2 adds the value 12 of the input code tr 1211 to the start address MAP10 of the map M1 previously stored in the memory area 40 of the map selection means 4, and adds the value 12 of the input code tr 1211 to the start address MAP10 of the map M1 previously stored in the memory area 40 of the map selection means 4, and adds the value 12 of the input code tr 1211 to the start address MAP10 of the map M1 previously stored in the memory area 40 of the map selection means 4. The output code of the address, that is, the 13th output code "49" in map M-1 is read (step 203 in FIG. 3(b)). And mapping means 2
passes the read output code "'49" to the program 5 shown in FIG. 1 (step 204 in FIG. 3(b)).
).

Such processing in steps 201 to 204 is performed every time a key on the keyboard 11 is pressed.

Therefore, if, for example, the key 12b is pressed in addition to the key 12a of the keyboard 11, the input code "14" corresponding to this key 12b is transmitted to the mapping means 2, and in response, the mapping means 2 outputs the input code ( L

Read the 15th output code "'51" of map M-1 based on the sum added to ARIO, and write this output code "
Pass the '51' to the program 5.

Further, if another map M-2 is selected in step 101, the map selection means 4 stores the start address MAR20 of map M-2.

In this case, for example, if the key 12a of the keyboard 11 is pressed, the input code "'12" corresponding to this key 12a is transmitted to the mapping means 2, and in response, the mapping means 2 inputs the input code "12". value 12

Therefore, the map selection means 4 selects each map M1, M-
By selecting one of the two types, it is possible to set the format of data to be passed to the program 5 in response to the operation of the keyboard 11 to either one of the two types. Of course, if a large number of maps are stored in the map storage memory 3 in advance, the format of the data passed to the program 5 can be changed in various ways by selecting any one of these maps.

FIG. 4 is a block diagram schematically showing a second embodiment of the keyboard input processing device according to the present invention.

In this embodiment, each map M-1 in the map storage memory 3

It is provided with a name map storage table 41 that stores maps 20 in correspondence with each other, and a name designation map storage memory 42 that stores the top address of the map when the name of the map is designated by the program 5. The mapping means 2 can access the name designation map storage memory 42 in the map selection means 4, and accesses the map storage memory 3 based on the top address of the map stored in this memory 42.

Next, the operation of this embodiment will be described according to the flowchart shown in FIG.

First, the map selection means 4 checks whether the name of the map to be selected has been specified by the program 5 (step 301 in FIG. 6(a)). For example, when the name of map M-2 is specified, the map selection means 4 temporarily prohibits the passing of event data from the keyboard 11 to the mapping means 2 (step 302 in FIG. 6(a)). During this time, it is checked whether the name of the map M2 instructed by the program 5 is stored in the name map management table 41 (step 30 in FIG. 6(a)).
