Description

Description: TECHNICAL FIELD The present invention relates to a data input device for inputting data constituting a document.

2. Description of the Related Art In recent years, as the penetration rate of printers has increased,
In many cases, printing of labels and the like is performed using a printer.

Hereinafter, a printing apparatus using a conventional data input device will be described. FIG. 4 is a control flow of the conventional data input device. First, it is determined whether the operated key is a character key or not, and if so, the character code is output. If it is not a character code, it is determined whether or not it is a long sound key, and if so, a long sound code is output and the process returns. If not, the next step is to identify whether it is a hyphen key, and if so, output a hyphen code and return. Otherwise, a process corresponding to the key is performed.

Problems to be Solved by the Invention However, in the case of the conventional data input device, a key for hyphen input and a key for long sound symbol input are separately provided, and key tops are provided with "-" and "-", respectively. Because similar labels are used, using a prolonged sign where hyphens should be used or using hyphens where a prolonged sign should be used can mean different meanings in the text. there were.

Means for Solving the Problems In order to solve the problem, the present invention provides a symbol key in which a hyphen and a prolonged sound symbol are defined, and when this key is operated, outputs a hyphen data in an alphabet input mode, and inputs a kana. In the mode, there is provided key data generating means for outputting long sound symbol data.

Operation With this configuration, a hyphen and a prolonged symbol are input in a distinguished manner in accordance with the input mode of the symbol key operation character.

Embodiment Hereinafter, a printing apparatus using a data input device according to an embodiment of the present invention will be described in detail.

First, FIG. 1 is a block diagram showing the configuration of the data input device of the present embodiment. Here, 1 is a keyboard having a plurality of key switches. Reference numeral 2 denotes an input control circuit having a key code generation unit for detecting a key operation of the keyboard 1 and outputting a key code corresponding to the operated key, and internally has a mode storage unit for determining whether the alphabet input mode is a kana input mode. Prepare. Reference numeral 3 denotes a central processing circuit which supervises the input control circuit 2 and other controls and performs control according to the flowchart of FIG. Reference numeral 7 denotes a program storage area for storing a control program according to the flowchart of FIG. 3, a Roman character conversion table for converting Roman characters expressed in alphabets to kana data, and a character code for converting key codes to character codes. This is a read-only memory having a table. Reference numeral 4 denotes a random access memory for storing final character data input from the keyboard 1. Reference numeral 5 denotes an output control circuit that controls the output of the contents of the random access memory to the printing unit 6. Reference numeral 6 denotes a printing unit that performs printing under the control of the output control circuit 5.

FIG. 2 is an external view of the operation surface of the keyboard 1. Here, 11 and 12 are mode switching keys, 11 is an alphabetic mode key, and 12 is a kana mode key. 13 is a character key in which the alphabet is defined. 14 is a symbol key in which a hyphen and a prolonged symbol are defined.

The operation of the data input device configured as described above will be described. First, when the alphabet mode key 11 or the kana mode key 12 of the keyboard 1 is operated, the input control circuit 2 stores the set mode in the mode storage unit. When the character key 13 is operated, the key code corresponding to the operated key is output to the central processing unit together with the mode data. Then, the central processing circuit 3 accesses the read-only memory 7 based on the transmitted mode data and key code data,
Get character code. For example, if the removed key code is "K" in the kana input mode, the key code of "A" is waited for after the next operated key code, and the Roman character conversion table is referred to when the next key code arrives. And output the character code of "ka". The output character code is stored in the random access memory 4.

Next, a control procedure when the symbol key 14 is operated will be described with reference to the flowchart of FIG. First, in step s1, the mode data and the key code from the input control circuit 2 which detected the operation of the symbol key 14 are received. Steps
In s2, it is determined whether the input mode is the kana mode or the alphabet mode. If the input mode is the kana mode, the process proceeds to step s3. Step s3, step
In s5, the character code table of the read-only memory 7 is accessed. Then, in step s4, since the long-sound symbol code is obtained, it is stored in the random access memory 4. Since a hyphen code is obtained at step s6, the hyphen code is stored in the random access memory 4 and the routine returns.

In the above description, the input mode has been described for the kana mode and the alphabet mode. However, the present invention is also effective when the katakana mode is included in the kana mode and the numeric mode is included in the alphabet mode.

Effect of the Invention As described above, the present invention defines a hyphen and a prolonged symbol and one key, and outputs the hyphen data or the prolonged symbol data depending on the mode state of the alphabet mode or the kana mode, At the same time as the number of keys is reduced, it is no longer necessary for the operator to discriminate between the key label of the hyphen key and the key label of the long vowel sign, which is apt to be confused in the related art.

Claims (1)

(57) [Claims] 1. A plurality of character keys in which alphabets are defined for each key, and either an alphabet defined in the keys or a kana expressed in Roman characters is input as input data in response to operation of the character keys. Mode switching means for switching the mode of whether or not, a symbol key in which a prolonged symbol and a hyphen are defined, and in the state of the alphabet input mode by the mode switching means, outputs hyphen data in response to operation of the symbol key, And a key data generating means for outputting long-symbol data in response to the operation of the symbol key in a kana input mode state.
