Description

[Detailed Description of the Invention] The present invention is a character processing system that performs processing such as editing on input characters and symbols, and then displays or records them to create any text including kanji, symbols, etc. It is related to the device.

A character processing device is generally equipped with a character input keyboard, encodes and processes input characters, and when displaying or recording further, converts the encoded data into a character pattern signal and converts the input characters into character pattern signals. is reproduced on a CRT, for example.

Because of this configuration, a character pattern generator for reproducing all the characters and symbols existing on the keyboard is incorporated into the device as an essential element.

Generally, however, in such devices, the characters on the keyboard are predetermined standard characters, and accordingly, the character pattern generator is also intended for standard characters.

Therefore, a problem arises in that it is not possible to process external characters that are characters other than the standard characters.

Therefore, in order to be able to process such non-standard characters, a character processing device can be considered in which a non-standard character pattern generator for non-standard characters can be set separately from a character pattern generator for standard characters.

In this case, in order to input a non-standard character, for example, a group of specific keys on the keyboard are associated with a non-standard character on the non-standard character pattern generator by numerical values, and by operating the specific key, a temporary character corresponding to the non-standard character is input. Create and enter a character code.

Then, by inputting the temporary character code to the non-standard character pattern generator, a pattern signal of the desired non-standard character can be obtained.

In the above way, you can also process non-standard characters,
Since external characters are originally special characters, only one part of the external characters is often sufficient when using the device.

Therefore, rather than making it possible to process all external characters with a character pattern generator consisting of one unit, it is possible to process an appropriate number of characters, for example about 60 types, with one unit, and then use other characters as needed. It is preferable to replace the unit with another one from the viewpoint of downsizing and preventing cost increases.

Therefore, in a device using this type of system, when inputting non-standard characters, the non-standard character pattern generator of a predetermined unit is set, and then, depending on the input characters, the unit is replaced as necessary, and the manual input of non-standard characters is performed. We will continue to do so.

However, once the external characters are stored in memory,
If you change the unit to input another custom character, if you leave it as is, it will not be possible to form a character pattern signal for the previously input custom character, and especially as mentioned above, temporary characters will be created for the custom character. In the case where a code is created, there is an inconvenience that an incorrect character pattern signal is formed.

Therefore, in view of the above-mentioned circumstances, the present invention has been developed to provide a system for detecting when an erroneous character pattern signal is generated, i.e., when the correct character pattern generator unit corresponding to the output data from the memory is not set. The purpose of this is to notify the operator of this, thereby preventing display and recording errors.

To summarize the present invention, when an input character is a non-standard character, the character code of the non-standard character is created by adding the unit code of the non-standard character pattern generator that was set at the time of input, and When the output data includes the above unit code, a comparison means is provided to compare the unit code of the external character and No. turn generator set at that time with the above unit code, and furthermore, this comparison means makes it possible to compare both the above unit codes. A notification means is provided to notify the operator if the external character pattern generator unit corresponding to the output data from the memory is not set.

Next, examples of the present invention will be described in detail.

FIG. 1 shows an external view of a character processing device that is an embodiment of the present invention.

In the figure, the main body 1 includes a CR as a display output device.
A T display device 10 and a printer 11 as a recording device are provided, and results of processing such as editing are displayed or recorded on these.

Note that the CRT display device 10 can also display input characters.

An input keyboard 12 is installed at the front of the main body 1, and this keyboard 12 includes a group of standard character keys 12a made up of standard characters and a group of non-standard character keys 12b.

In addition, a unit coupling part 13 for setting the custom character pattern generator unit 20 is provided near the group 12b of characters containing custom characters, and a connector (not shown) for connecting the unit 20 is provided here. ) is attached.

The non-standard character pattern generator unit 20 displays the non-standard characters that the unit has on the unit surface 21, and furthermore, in order to associate these characters with the input key group 12b numerically, each non-standard character is assigned a numerical value. has been done.

Therefore, if you press any key in the group 12b containing private characters, any of the private characters on the unit surface 21 associated with that key by numerical value will be specified, and as a result, the temporary character of the specified private character will be specified. The character code will be input.

In addition, the connector 22 exposed to the outside of the unit 20
is for connecting to the connector attached to the unit coupling section 13 described above.

Next, a block diagram of the main parts of the character processing device of this embodiment is shown in FIG.

In the same figure, the standard character input circuit 30 detects a pressed key of the standard character input key group 12a shown in FIG.
The encoding circuit 31 is a circuit that creates a key signal, and converts this key signal into a character code.

In addition, the external character input circuit 32 inputs external character characters into a group 12.
In the circuit that detects the pressed key of b and creates a key signal, the encoding circuit 33 creates a code for this key signal and adds the currently set unit code of the external character pattern generator to the code. do.

Therefore, the output of the encoding circuit 33 will be different character codes even if the same key is pressed, depending on the set external character pattern generator unit.

The character codes created as described above are both input into the memory 34 and stored in the order of key input.

Then, the input character codes are edited, arranged, and stored again by a control device (not shown).

Next, the operation of converting the character code stored in the memory 34 into a character pattern signal and displaying or storing it will be explained.

The output data from the memory 34 is temporarily stored in the buffer 35 in order for each character code.

The detection circuits 36 and 37 detect whether the character code stored in the buffer 35 is a standard character code or a temporary character code of a non-standard character, and if it is the former, the gate 3
8 is opened, and if it is the latter, one condition is set to open the gate 39.

When the gate 38 is opened, since the character code stored in the buffer 35 is a standard character, the character code in the buffer 35 is input to a standard character pattern generator 40 fixedly provided in the device, and the corresponding character pattern is generated. A signal is formed.

On the other hand, if the content stored in the buffer 35 is a temporary character code representing a non-standard character, the unit code of the non-standard character pattern generator set at the time of inputting the non-standard character should be added.

The comparison circuit 41 monitors the presence or absence of the unit code in the data stored in the buffer 35, and if the code is present, compares it with the currently set unit code of the external character pattern generator 42, and if both unit codes match, the gate is activated. Set one condition for opening 39.

If they do not match, a mismatch signal is sent to the notification circuit 43.
and notify the operator.

When the comparison circuit 41 detects a match, the detection circuit 3
Since a non-standard character is detected in step 7, the two conditions for opening the gate 39 are satisfied, and as a result, the contents of the buffer 35 are sent to the currently set non-standard character pattern generator 42, which generates a fixed character pattern. A signal is formed.

That is, the gate 39 opens when the non-standard character pattern generator unit set at that time and the non-standard character pattern generator unit set at the time of inputting the relevant non-standard character are the same.

Therefore, if the unit of the custom character pattern generator 42 is changed after inputting a custom character consisting of .

The character pattern signal generated by the character pattern generator 40° 42 by the above operation is transmitted to the CRT display control circuit 44.
The signal is then output to the printer control circuit 45, converted into a certain image signal or recording signal, and sent to the CRT display device 10 and printer 11, where it is displayed or recorded as characters.

The unit code of the external character pattern generator 42 is
For example, 16 types of codes can be expressed using four lines.

In this case, the unit code added by the encoding circuit 33 and the two unit codes input to the comparison circuit 41 each consist of 4 bits.

Further, the notification circuit 43 may provide notification by, for example, a lamp display or a buzzer sound, but it may also be provided by blinking the display position of the CRT display device 10.

Furthermore, it is also possible to display the unit number of the correct non-standard character pattern generator at the same time.

In this case, the unit code output from the buffer 35 to the comparison circuit 41 may be detected, the code may be converted into a numerical character pattern signal, and the unit number may be displayed on the CRT display device 10.

As described above, in this embodiment, the encoding circuit 33 adds the unit code of the non-standard character pattern generator.
There are two methods: adding the character code as is to the input key signal from the character code, and creating a character code by using the upper or lower character code as the unit code and the lower or upper character code as the code of the key signal.

In the latter case, for example, if the character code is composed of 8 bits, the upper or lower 4 bits become the unit code area.

In that case, by appropriately setting the unit code, it becomes possible to completely distinguish between the standard character code created by the encoding circuit 31 and the temporary character code from the encoding circuit 33. .

Therefore, in this case, the detection circuits 36 and 37 can be omitted, and the character pattern generators 40 and 42 each independently determine whether the data from the buffer 35 corresponds to a standard character or a non-standard character. You will have to decide what it is.

This determination is not made directly by the character pattern generators 40 and 42, but character pattern generation is usually done in a ROM (Resource).
Since the input data specifies the character pattern stored in the ROM (ad only memory), it can be immediately known whether the input data specifies the character pattern stored in the ROM or not by whether there is an output or not. Therefore, the standard character pattern generator 40
If there is an output to the character pattern generator 42, it can be determined that the data in the buffer 35 is data corresponding to a standard character, and if there is an output to the non-standard character pattern generator 42, it can be determined that the data in the buffer 35 is data corresponding to a non-standard character. This is the translation.

Utilizing this fact, the comparison circuit 41 can also be omitted.

That is, if there is no output from either of the character pattern generators 40 and 42 after data is stored in the buffer 35, the currently set external character character pattern generator unit converts the data in the buffer 35 into a predetermined character. Since it is considered to be different from the unit that converts into a pattern signal, it is possible to detect that the outputs of both character pattern generators 40 and 42 are not output at the same time and operate the notification circuit 43.

However, even in such a case, it can be considered that the unit code of the buffer 35 and the currently set unit code of the non-standard character pattern generator 42 are substantially compared.

As described in detail in the embodiments above, according to the present invention, while incorporating the advantages of a character processing device in which a plurality of units of non-standard character pattern generators are provided and these can be arbitrarily set to process a desired non-standard character, Also, errors in the display or recording of non-standard characters that may occur due to this can be prevented.
