Abstract

PURPOSE:To use the combination of plural kinds of keyboards by using plural connection parts and keyboard identification (ID) information. CONSTITUTION:Plural connection parts 3, 4 and the keyboard ID information are used for controlling plural kinds of keyboards 1, 2. In the case of storing a hardware code in a hard buffer 6 by a hardware code inputting part 5, the keyboard ID information is added to the hardware code and stored in the code buffer 6. A code conversion part 7 decides which keyboard inputs the code in accordance with the ID information, converts the hardware code into a character code in accordance with a code conversion table 8 when the code is inputted from the keyboard 1, or a code conversion table 9 in the case of the code inputted from the keyboard 2 and then transfers the converted code to a main storage part 10. Consequently, a converted character code can be accurately transferred to the main storage part 10 independently of the sort of the keyboard used for the input of a hardware code.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an electronic computer.

[Prior Art] The configuration of a conventional electronic computer is shown in FIG. A hardware code acquisition section 5 acquires a hardware code generated when a key is pressed from the keyboard 1 connected to the connection section 3, and stores it in a food buffer 6. The code conversion section 7 takes out the stored hardware from the code buffer, compares it with the code conversion table 8, converts the hardware code into a character code in a format that can be processed by the main storage section 10, and passes it to the main storage section 10. The code conversion table 8 needs to have a plurality of tables because different types of keyboards may have different combinations of manually input characters and generated hardware codes. For this reason, the code conversion section 7 normally checks the type of the connected keyboard 1 when the device is powered on, and uses the code conversion table 8 that matches the keyboard 1. For this reason, only one keyboard could be connected to conventional electronic computers.

[Problems to be Solved by the Invention] If the user of the above-mentioned conventional electronic computer wants to use a different type of keyboard, there is a drawback that the user must turn off the power to the device and replace the keyboard.

[Means for Solving the Problems] The present invention provides a computer that includes a connection section, a hardware code import section, a code conversion section, and a code conversion table. The present invention is characterized in that a plurality of keyboards and a plurality of types of keyboards can be controlled using keyboard identification information.

[Example code] Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. This embodiment includes keyboards 1 and 2, connection sections 3 and 4, hardware code import section 5, code buffer 6, code conversion section 7, code conversion tables 8 and 9, and main storage section 10.
and.

In the case of the embodiment shown in FIG.
When storing a hardware code in the code buffer 6, in order to distinguish whether the hardware code is from the keyboard 1 connected to the connection part 3 or the hardware code from the keyboard 2 connected to the connection part 4, The identification information is added and stored in the code buffer 6.

The code conversion unit 7 extracts the code from the two keyboards 1 and 2 and determines whether it is the hardware code from the keyboard 1 or the hardware code from the keyboard 2 based on the added keyboard identification information.

If it is a hardware code from keyboard 1, it is converted into a character code according to code conversion table 8 for keyboard 1, and if it is a hardware code from keyboard 2, it is converted into a character code according to code conversion table 9 for keyboard 2. Pass it to 10. As a result, regardless of whether the two keyboards 1 and 2 use the same code conversion table 8 or different code conversion tables, the correctly converted character code is passed to the main memory no matter which keyboard is used. becomes possible.

Also, since the code conversion tables 8 and 9 are referenced for each code conversion, even if input from keyboard 1 and input from keyboard 2 are mixed, the input to main storage unit 10 is from two keyboards. It is possible to pass the character code without being aware of it.

[Effects of the Invention] As explained above, the present invention has the advantage that a plurality of keyboards can be controlled, and different types of keyboards can be freely replaced, or a plurality of keyboards can be used in combination. .

Claims (1)

[Scope of Claims] 1. In an electronic computer equipped with a connection section, a hardware code import section, a code conversion section, and a code conversion table, keyboard identification information is used to distinguish between a plurality of connection sections and which connection section. An electronic computer characterized in that it can control multiple units and multiple types of keyboards. 2. The electronic computer according to claim 1, wherein there are two keyboards and two types of keyboards.
