Abstract

PURPOSE:To apply simply a code processing at an external device connected to a keyboard by enerating a conversion code of 2-byte form including non- conversion from an input code. CONSTITUTION:When a key is depressed at first, a key state read section 1 reads an input key and the reading is formed to a microprocessor section 2. The processing section 2 discriminates whether the said input data is a data to be subject to Kana (Japanese syllabary)/Kanji (Chines character) conversion, a data to be subject to code conversion because of shift-key depressed at the same time, or a data to be outputted while being converted into a 2-byte form with a predetermined code added simply to a conventional 1 byte code or the like, and various kinds of required code conversion jobs are executed according to the procedure of a program section 3 while a data table section 4 is being referenced. Then only the required data is outputted via an intervace section 5 to an external device while being unified into a 2-byte form code.

Description

[Detailed description of the invention] [Field of industrial application] The present invention performs kana-kanji conversion, code conversion when the shift key is pressed, etc. within the keyboard, and converts all output data to "2".
Regarding keyboards that output bytecode.

〔overview〕

The present invention provides a keyboard equipped with an input key that generates a ``1'' byte format code and a conversion key that generates a conversion command that performs conversion, including no conversion, on this code. By generating converted codes that have undergone conversion, including non-conversion, from input codes, it is possible to easily process the codes in an external device connected to the keyboard.

[Conventional technology]

The code output from the conventional keyboard is JISC62
20 information exchange code is a 7 or 8 unit "1" byte code shown in the extension method of JIS C6228 information exchange code, and the "2" byte code shown in the JIS C6226 information exchange kanji code system is a keyboard code. It is impossible to create and output within. Furthermore, when a large number of functions are required, a method of pressing a function key while holding down a shift key is generally used.

[Problem that the invention seeks to solve]

However, such a conventional terminal control device for reading data output from a keyboard has a disadvantage in that the processing route for data output from the keyboard must be changed depending on the state of the shift key.

The present invention has been made to solve these drawbacks, and aims to provide a keyboard that can handle the various code conversion processes performed by terminal control devices and the like.

[Means for solving problems]

The present invention is a keyboard that is equipped with an input key that generates a code with a length of rlJ bytes, and a conversion key that generates a conversion command that performs conversion, including no conversion, of the input code generated by this input key. As a means for solving the problem, the present invention is characterized by comprising a converting means for converting the input code based on the conversion command to generate a converted code having a length of "2" bytes.

[Effect]

A conversion means that includes a microprocessor built into the keyboard converts an IJ byte length code generated by an input key to ``2'' in response to a conversion request such as kana-kanji conversion or code conversion when the shift key is pressed. A byte-length code is generated, and a "2" byte-length code with rlJ bytes added is generated in response to a no-conversion request.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS A device according to an embodiment of the present invention will be described below with reference to the drawings.

The figure is a block configuration diagram showing the configuration of the apparatus of this embodiment. First, the configuration of this embodiment device will be explained based on the drawings. This embodiment device includes a key type a reading section for reading the pressed state of a key, a microprocessor section 2 for converting various codes and controlling the entire keyboard based on the information obtained from the key state reading section 1; A program unit 3 that records the operating procedures of this microprocessor, a data table unit 4 that has information for performing various code conversions, and an interface unit 5 that interfaces the keyboard with external equipment such as a terminal control device. Equipped with.

Next, the operation of this embodiment device will be explained based on the drawings.

First, when a key is pressed, the key state reading unit 1 reads the input key and notifies the microprocessor unit 2 of the input key. The microprocessor unit 2 determines whether this input data is data to be converted into kana-kanji, data whose code is to be converted because the shift key is pressed at the same time, or data which is simply a conventional "1" byte code. It is determined whether the determined rlJ bytecode is added to this data and converted into a "2" bytecode format to be output. Various necessary code conversion operations are performed accordingly. Thereafter, only the necessary data is sent to an external device such as a terminal control device via the interface section 5 in a unified code in the form of a "2" byte code.

〔Effect of the invention〕

As explained above, the present invention provides "2" that is unified to external equipment such as a terminal control device to which the output of the keyboard is connected.
Since a byte-length code is output, it has the effect of simplifying the configuration of these external devices.
