Description

  The present invention relates to an operation data output device, an operation data output method, and a program for converting character string data into operation data and supplying it to an information processing means.

Conventionally, a reading result character string obtained by decoding a code symbol in a reading device such as a code reader is transferred to an information processing device such as a PC (personal computer), and the information processing device counts, edits, etc. A technique for performing the above process is known.
In this transfer, the reading device is connected to a keyboard terminal of the information processing device (may be a general-purpose terminal such as a USB (Universal Serial Bus)), and the key operation of the keyboard corresponding to the character string of the reading result is read from the reading device. A technique for outputting operation data indicating the above is also known.
By using this technique, it is possible to input a character string as a read result for an application operating on the information processing apparatus in the same manner as when inputting characters from the keyboard.

  By the way, code symbols such as barcodes were originally used to symbolize only numerical values and alphabets, so that meaningful information itself has been symbolized and kanji characters have been used as in recent years. However, it can be said that the efficient output method is still developing. Therefore, when trying to output operation data as described above, there are the following problems.

  First, for a single-byte character, the correspondence between the character and the key to be operated is relatively simple. For example, if the reading result is the number “1”, the operation for inputting it is “make” (make: on operation) and break (break: off operation) of the key “1” in this order. Is what you do.

However, in the case of a multi-byte character (for example, a so-called full-width two-byte character), the key operation for inputting the corresponding character is complicated, and character input assist software (Windows ( (Registered Trademark) also called IME (Input Method Editor). Therefore, it has been difficult to appropriately generate operation data for inputting multi-byte characters.
In order to solve this problem, for example, it is conceivable that a dedicated conversion application for processing key operation data transmitted from the reading device is installed on the information processing device side.

Character input in this configuration will be described with reference to FIG.
In the PC 400 of FIG. 9, the keyboard driver 401 has a function of receiving operation data from the keyboard, converting it into a format that can be processed by an OS (Operating System) 410 and passing it to the OS 410. A keyboard driver 401 corresponding to a normal keyboard is generally provided together with the OS 410.

  The conversion application 402 is an application provided by the manufacturer of the reading device 300, and has a function of acquiring operation data passed from the keyboard driver 401 to the OS 410 on the way using a keyboard hook, partially processing it, and passing it to the OS 410. That is, a specific combination of key operations is replaced with data indicating input of a multi-byte character (in the case of Windows (registered trademark), a WM_IME_CHAR message can be used) and passed to the OS 410.

  The OS 410 is basic software for managing the entire PC 400 and provides basic functions that can be used from various applications by controlling the hardware. FIG. 9 simply shows functions related to character input from the keyboard. .

Based on the virtual key code received from the keyboard driver 401, the input processing unit 411 passes information indicating the input content to the active application. For example, when the “1” key is pressed, information indicating that the 1-byte character “1” has been input is given. In the example of FIG. 9, it is assumed that an editor 420 that is an application for counting and editing the character string of the read result is active.
In addition, when receiving a virtual key code or message indicating input of a multi-byte character, the input processing unit 411 passes information indicating input content to the character input auxiliary unit 412 instead of directly passing it to the editor 420.

The character input auxiliary unit 412 shows a function realized by the above-described character input auxiliary software, and provides a function of assisting the input of multi-byte characters such as kana-kanji conversion based on key operations. When the character to be input is confirmed, information indicating the confirmed input content is passed to the active application.
In addition, the input processing unit 411 can directly instruct the input of a multi-byte character by designating the character code directly (without performing kana-kanji conversion) by passing the above-described WM_IME_CHAR message to the character input auxiliary unit 412, for example. It is.

A reading apparatus 300 having a function of reading and decoding a code symbol with respect to such a PC 400 includes a portion including a character code of a 1-byte character in character string data of a read result, and a plurality of bytes (here, 2 bytes). Operation data is output with a different algorithm depending on the part containing the character code of the (byte) character.
First, in the case of a 1-byte character, as the operation data for instructing the OS 410 to input the character, the operation data of the key corresponding to the character code and the break operation data are output in order. For example, if the character string “12A” shown in FIG. 9 is arranged, for “1” and “2”, the operation data of “make” and “break” are output in order for the “1” or “2” key. Good. “Key 1” and “key 2” in the figure indicate this operation data.

  In addition, a shift key operation is necessary for some characters. In this case, the operation data may be output in the order of shift key make → character corresponding key make → same key break → shift key break. In the example of FIG. 9, “A” corresponds to this case, and “Shift + Key A” in the figure represents this operation data.

  On the PC 400 side, the operation data is passed from the keyboard driver 401 to the conversion application 402. The conversion application 402 passes the received operation data to the input processing unit 411 of the OS 410 as it is unless the operation data instructing conversion is included. If the input processing unit 411 is not in the multi-byte character input mode, the received operation data does not include data for instructing the input of the multi-byte character, so that the input instruction for the character corresponding to the operated key is input. And the information that the corresponding character has been input is passed to the editor 420. In this example, “12A” is passed as an input character string corresponding to the operation data. As a result, the character string can be input to the editor 420.

On the other hand, in the case of a multi-byte character, the reading device 300 first transmits key operation data for instructing conversion to the multi-byte character to the conversion application 402, and then selects the character to be input to the conversion application 402. Output key operation data to specify.
The former operation can be arbitrarily determined by the designer of the conversion application 402. Here, the L key is turned on while the ALT key is turned on. Specifically, ALT key make → L key make → L key break → ALT key break. “ALT + key L” indicates this operation data.

  The latter operation can be arbitrarily determined by the designer of the conversion application 402. Here, the operation is to input the character code of the shift JIS of the character to be input as text. For example, the character code of “Rain” Shift JIS is “0x89 0x4A”, so if you want to input “Rain”, send operation data to type “894A” with each byte connected except “0x” To do.

On the PC 400 side, the operation data is passed from the keyboard driver 401 to the conversion application 402 as in the case of single-byte characters. When the conversion application 402 detects operation data of ALT + key L, the conversion application 402 interprets a predetermined number of key inputs thereafter as input of a character code of Shift JIS, and inputs the key operation data. It is converted into data indicating the input of a multi-byte character having a character code and passed to the OS 410.
Then, the input processing unit of the OS 410 passes the received data to the character input auxiliary unit 412 because it is data for instructing input of a multibyte character. The character input auxiliary unit 412 interprets the data as a character input instruction specifying a character code, and passes information indicating that the corresponding character has been input to the editor 420. In this example, “rain” is passed as an input character string. As a result, the character string can be input to the editor 420.

As described above, the reading apparatus 300 can convert both 1-byte characters and 2-byte characters into operation data of the keyboard and transmit them to the PC 400 and input the characters to the editor 420.
However, in the method shown in FIG. 9, it is necessary to install a dedicated conversion application 402 in the PC 400. Further, from the viewpoint of the manufacturer of the reading apparatus 300, it is necessary to develop the conversion application 402, distribute it to the user, and explain the installation method. Furthermore, if the conversion application 402 does not operate depending on the user's environment, it may be necessary to modify the application to solve the problem.
For this reason, the method shown in FIG. 9 is a time-consuming method for both the manufacturer and the user.

As a general rule, additional installation of an application may cause a security problem, and may cause unstable operation due to compatibility with the host. For this reason, with the recent increase in security awareness, there have been cases where application installation is not preferred or difficult.
A similar problem also occurs when a character string obtained by other than reading a code symbol is output to the information processing apparatus.

  The present invention has been made in view of such a background, and an object of the present invention is to make it possible to easily provide a character string including a multi-byte character as operation data of a keyboard for information processing in an information processing means. And

In order to achieve the above object, the operation data output device of the present invention reads character codes and decodes them to obtain character string data in which character codes of 1-byte characters and multi-byte characters are mixed. And a portion including a character code of a 1-byte character and a portion including a character code of a multi-byte character in the character string data acquired by the character string data acquisition means , and a 1-byte character and a plurality of bytes Generating means for generating operation data of a keyboard for instructing a predetermined operating system to input a character indicated by the character code by an algorithm different from the character; and information processing means for generating the operation data generated by the generating means And an output means for outputting to.
Further, another operation data output device of the present invention includes a character string data acquisition unit that acquires character string data in which character codes of 1-byte characters and multi-byte characters are mixed by reading and decoding code symbols, A generating unit that generates keyboard operation data based on a character code included in the character string data acquired by the character string data acquiring unit, and an output unit that outputs the operation data generated by the generating unit to the information processing unit; The generation unit identifies a portion including a character code of a 1-byte character and a portion including a character code of a multi-byte character among the character string data acquired by the character string data acquisition unit, and the character string data (A) As the operation data corresponding to the character code of the multi-byte character, the operation data indicating the make of the special key, the character code For each digit of the value obtained by converting to a hexadecimal number, the operation data indicating the make and break of that key on the keypad is changed from the most significant digit to the least significant digit, and the special key break. (B) As the operation data corresponding to the character code of the 1-byte character, the operation data indicating the operation of the key corresponding to the character code, and the operation of the shift key as necessary Is generated.
In these data output devices, the output means refers to each byte of the character string data in order from the top, and determines whether each byte is a byte of a value that is not used in a 1-byte character. It is preferable to distinguish between a portion including the character code and a portion including a multi-byte character code .
Furthermore, a means for switching on / off the recognition of multi-byte characters is provided, and when the recognition of multi-byte characters is off, the generating means is a character code in which all the character codes included in the character string data are 1-byte characters. The operation data may be generated as follows.
In addition to being realized as an apparatus , the present invention can be realized in any form such as a system, a method, a program, and a medium.

According to the operation data output device and operation data output method of the present invention as described above, a character string including a multi-byte character can be easily subjected to information processing in the information processing means as keyboard operation data.
According to the program of the present invention, the same effect can be obtained by causing the computer to read and execute the program.

It is a figure which shows the function structural example of a reader and PC for demonstrating the subject of this invention.

Hereinafter, embodiments for carrying out the present invention will be specifically described with reference to the drawings.
First, FIG. 1 shows a configuration of an information processing system provided with a reading device which is an embodiment of the operation data output device of the present invention.
The information processing system shown in FIG. 1 includes a reading device 100 that reads a code symbol and outputs the reading result, and a personal computer (PC) that is an information processing device that receives, stores, and analyzes the reading result output by the reading device 100. 200).

  The reading apparatus 100 is connected to a keyboard terminal (may be a general-purpose terminal such as a USB (Universal Serial Bus)) of the PC 200. When the code symbol is read and successfully decoded, the character string of the read result obtained by the decoding is output as operation data indicating a keyboard operation for inputting the character string to the PC 200.

Next, FIG. 2 shows a hardware configuration of the reading apparatus 100.
The reading device 100 is a device that reads a code symbol provided on a reading target and in which modules having different light reflectances from the surroundings are arranged, and includes an optical head unit 110 and a decoder unit 120. In addition to these, an operation unit such as a button for accepting a user operation is also shown, but the illustration thereof is omitted. The format of the code symbol is arbitrary, and codes of any format such as a one-dimensional bar code, a two-dimensional bar code, and a QR code (registered trademark, the same applies hereinafter) can be read according to the setting of the decoder unit 120. It is.

The optical head unit 110 includes a lens 111 and a CMOS that is an example of a solid-state image sensor.
(Complementary Metal Oxide Semiconductor) An image sensor (hereinafter simply referred to as “CMOS”) 112 and a light emitting LED (light emitting diode) 113 are provided.
The lens 111 is an optical lens, for example, for taking an image of a reading object into the optical head unit 110 and forming an image on the imaging area of the CMOS 112.

The CMOS 112 captures an image of an object to be read by reflected light from an object to be read (which is assumed to include a code symbol) taken in by the lens 111, and expresses it as a digital luminance value from an analog image signal obtained by the imaging. The generated image data is generated and output to the decoder unit 120.
The projection LED 113 is an illuminating unit for illuminating the reading object with the irradiated light so that a clear image can be captured by the CMOS 112. However, the projection LED 113 may not be provided depending on the structure of the apparatus.

Next, the decoder unit 120 includes a first input / output interface (first I / O) 121, a control circuit 122, a RAM 123, a nonvolatile memory 124, and a second input / output interface (second I / O) 125.
Among these, the first I / O 121 is an interface for transmitting and receiving control signals, image data output from the CMOS 112, and the like between the optical head unit 110 and the decoder unit 120.

  The control circuit 122 controls the CMOS 112 and the projection LED 113, and performs filter processing for noise removal and image data for decoding preparation on the image data of the reading target input from the CMOS 112 via the first I / O 121. Processing, decoding of code symbols based on processed image data, accumulation of read results after decoding, processing, output processing, and the like are performed. The hardware can be configured by an ASIC (Application Specific Integrated Circuit) or a CPU. In addition, about the detail of a decoding process, what is necessary is just to employ | adopt well-known arbitrary methods, such as the method of Unexamined-Japanese-Patent No. 2005-25417, for example.

  The RAM 123 temporarily stores the image data input from the CMOS 112, is used as a work memory during data processing for decoding preparation, temporarily stores the read results after decoding, and other reading The storage unit stores data that is dynamically changed, such as data necessary for the operation of the apparatus 100. Some may be non-volatile.

The non-volatile memory 124 is a non-volatile storage unit that stores a program for starting the reading device 100, a program for causing the CPU of the control circuit 122 to execute, and the like.
The second I / O 125 is an interface for performing data communication with an external device such as the information processing device 200, and the read result after decoding by the control circuit 122 is transmitted to the external device via the second I / O 125 as keyboard operation data. Can be output.
On the other hand, the PC 200 may have a known configuration including a CPU, ROM, RAM, HDD, communication interface, and the like as hardware. As for software, if only reading results are input from the reading device 100, only software included in advance in the OS is sufficient.

Next, FIG. 3 shows a functional configuration of a part of the reading apparatus 100 related to the feature of this embodiment.
As shown in FIG. 3, the reading apparatus 100 includes a reading unit 131, a decoding unit 132, a character identification unit 133, a 1-byte character corresponding operation data generation unit 134, a multibyte character corresponding operation data generation unit 135, and an operation data output unit 136. Is provided.

Among these, the reading unit 131 has a function of reading a code symbol by imaging or scanning the code symbol.
The decoding unit 132 has a function of decoding code symbols based on image and waveform data obtained by the reading unit 131 to obtain character string data as a reading result.

The character identification unit 133 has a function of identifying a portion including a character code of a 1-byte character and a portion including a character code of a multi-byte character in a character string obtained as a result of decoding by the decoding unit 132. For example, when each byte of the character string data of the decoding result is referred to in order from the top, and there is a byte of a value that is not used in a 1-byte character (or a byte of a value that is used in a multi-byte character), It can be determined that the subsequent byte is a byte indicating a character code of a multi-byte character.
Since this standard differs depending on the type of character code to be used, the type of character code to be used is set in advance in the character identification unit 133. You may enable it to change this according to a user's operation or automatically.

  The 1-byte character corresponding operation data generation unit 134 instructs the OS of the PC 200 to input the character indicated by the character code of the portion that includes the character code of the 1-byte character in the read result according to the determination result of the character identification unit 133. A function for generating keyboard operation data is provided.

The multi-byte character corresponding operation data generation unit 135 instructs the OS of the PC 200 to input the character indicated by the character code of the portion including the character code of the multi-byte character in the read result according to the determination result of the character identification unit 133. A function for generating keyboard operation data is provided.
A specific algorithm for generating these operation data will be described later.
The operation data output unit 136 has a function of outputting the operation data generated by the 1-byte character corresponding operation data generating unit 134 or the multi-byte character corresponding operation data generating unit 135 to the PC 200.

Next, operation data output from the reading device 100 and handling of the operation data on the PC 200 side will be described with reference to FIG.
As shown in FIG. 4, in this embodiment, the keyboard driver 201 and the OS 210 are involved in handling operation data on the PC 200 side. The keyboard driver 201 and OS 210 may be the same as the keyboard driver 401 and OS 410 shown in FIG. However, the conversion application 402 shown in FIG. 9 is not necessary.
Here, the OS 210 is described as being Windows (registered trademark).

The editor 220 is an application that counts and edits the character string of the reading result. A text editor included in advance in the OS may be used as long as the application can input a character string at the minimum.
In addition, the character input auxiliary unit 212 uses a unit suitable for the language to be used. That is, for example, when trying to input Japanese, a Japanese input program is used.

The operation data output from the reading apparatus 100 to the PC 200 is the same as that described with reference to FIG. That is, it is the operation data for the key corresponding to the character code, which is operation data for instructing the OS 210 to input the character indicated by the character code (generated by the 1-byte character corresponding operation data generation unit 134).
However, for multi-byte characters, unlike the case described with reference to FIG. 9, operation data for instructing the OS 210 to input the character indicated by the character code is output (the multi-byte character corresponding operation data generation unit 135 generates To do).

  Here, when the OS is Windows (registered trademark), the input processing unit 211 included in advance in the OS is obtained by converting a hexadecimal character code into a decimal number while pressing the ALT key that is a special key. A function that accepts the operation of inputting the number from the most significant digit to the least significant digit of the numeric value in order with the keypad (numeric keypad) and releasing the ALT key as a multi-byte character input operation of the character code. ing. When the input processing unit 211 receives the operation data indicating this operation, the input processing unit 211 instructs the character input auxiliary unit 212 to input a multi-byte character having the character code specified by the operation instead of the operation data. Pass data.

Therefore, the character “rain” having the character code “0x894A” in the shift JIS format is 35146 when “0x894A” is converted to a decimal number, so that while pressing the ALT key, 3, 5, 1, 4, Input can be performed by pressing the keys No. 6 in this order and then releasing the ALT key.
Using this function, the reading apparatus 100 outputs operation data for instructing the OS 210 to input desired multi-byte characters.

In the case of the example of FIG. 4, in order to input the character “rain” having the character code “894A”, make the ALT key → make 3 keypad and break (“keypad 3” indicates this key operation. In the same manner, operation data is output in the order of make and break of the keypad 5, 1, 4, 6 key → break → ALT key break (generated by the multibyte character corresponding operation data generation unit 135).
When two or more multi-byte characters are to be input consecutively, operation data indicating that the ALT key is pressed, the numeric value is input on the keypad, and the ALT key is released is output for each character.

In this way, without installing a dedicated conversion application on the PC 200 side, if the OS is installed in a general manner, the reading device 100 outputs only using functions that are almost certainly provided. Multi-byte characters can be input by keyboard operation data.
Therefore, it does not take time for development, distribution, explanation, installation, update, etc. of the dedicated application, and it is not affected by the environment on the user side, and multi-byte characters can be easily input.

Next, a process for outputting the operation data shown in FIG. 4 will be described.
FIG. 5 shows a flowchart of processing executed by the CPU of the control circuit 122 when the code symbol is successfully decoded.
When the decoding of the code symbol read by the optical head unit 110 is completed in the control circuit 122, the character string data of the read result can be acquired. Therefore, the CPU of the control circuit 122 starts the process shown in the flowchart of FIG. 5 in order to generate operation data for inputting the character string indicated by the character string data to the PC 200.

In this process, first, the first byte of the read result is set as a processing target (S11).
Next, it is determined whether or not the multi-byte character processing is set to ON (S12). This setting is a setting as to whether or not to output operation data in consideration of multi-byte characters, and can be switched ON / OFF by the user operating an appropriate operation unit. When this is OFF, the operation data is generated and output on the assumption that the data in the character string of the read result does not include a multi-byte character code, that is, the read result includes all 1-byte characters.

Therefore, in the case of NO in step S12, key operation data corresponding to the value of the processing target byte is generated and output from the second I / O 125 (S16), and then the key corresponding to the value of the processing target byte is generated. Break operation data is generated and output from the second I / O 125 (S17).
These operation data are operation data indicating a key operation for instructing the OS 210 to input a character indicated by the character code of the processing target byte. If the character to be input is an uppercase alphabet or a symbol and a shift key operation is required for input, a shift key make is generated before step S16 and a shift key break is generated and output after step S17. The description is omitted for simplification.

After step S17, it is determined whether or not the processing of all the character string data of the decoding result has been completed (S15). If it has been completed, the processing is terminated. If not completed, the next byte of the read result is set as a processing target (S18), the process returns to step S12, and the process is repeated.
If “YES” in the step S12, it is determined whether or not the processing target byte is a part of a code indicating a multi-byte character (S13). This determination can be made based on the value of the processing target byte as described above.

If NO in step S13, that is, if the processing target byte indicates a character code of a 1-byte character, the process proceeds to step S16, and a key operation for instructing the keyboard driver 201 to input the character indicated by the character code The operation data indicating is generated and output.
In the case of YES in step S13, after the multi-byte character output process shown in FIG. 6 is performed (S14), the process proceeds to the determination in step S15 whether or not the process for all the character string data of the decoding result has been completed.

Next, FIG. 6 shows a flowchart of multibyte character output processing.
In this process, the CPU of the control circuit 122 first specifies a place where a character code for one multibyte character including a processing target byte is arranged (S21). Next, the multi-byte character code indicated at the specified location is converted into a decimal number (S22).

  Next, operation data for a special key (for example, ALT key) make is generated and output from the second I / O 125 (S23). Then, while increasing i from 1, for the i-th digit n from the decimal number obtained in step S22, operation data for make and break of the key of the number on the keypad are sequentially generated and output ( S24-S29). Then, after sequentially outputting from the most significant digit to the least significant digit (NO in S29), operation data for the special key break is generated and output (S30).

The operation data generated and output here is operation data indicating a key operation for instructing the OS 210 to input a multi-byte character of the code indicated at the location specified in step S21.
Then, after step S30, the part specified in step S21 in the decoding result is regarded as processing completion (S31), and the processing returns to FIG. In this case, when the process proceeds from step S15 to step S18 in FIG. 5, the next byte after the location specified in step S21 is to be processed.

  5 and 6, the character string data obtained as a result of reading by the control circuit 122 is distinguished from a portion including a 1-byte character code and a portion including a multi-byte character code. The operation data for instructing the OS 210 to input the character indicated by each character code can be generated and output to the PC 200.

Although the description of the embodiment is completed as described above, it is a matter of course that the configuration of the apparatus, specific processing contents, and the like are not limited to those described in the above-described embodiment.
For example, in the above-described embodiment, the OS operating on the PC 200 has been described as Windows. However, the OS may be connected to a PC on which another OS is operating. In this regard, the key operation for instructing the OS to input 1-byte characters is basically the same in any OS. However, it is conceivable that the key operation for instructing the OS to input multibyte characters differs depending on the OS.

  Accordingly, an algorithm for generating operation data for instructing the OS to input a multi-byte character of the code based on the code of the multi-byte character in association with each of the plurality of OSs in the reading device 100. It is good to memorize. Then, according to the OS designation operation from the user, the algorithm used by the multi-byte character handling operation data generation unit 135 to generate the operation data is changed to an algorithm corresponding to the OS designated by the designation operation. Good.

That is, as shown in FIG. 7, an OS designation unit 137 for selecting an OS in accordance with an OS designation operation from the user is provided, and the multi-byte character correspondence operation data generation unit 135 is connected to the OS designated by the OS designation unit. A corresponding algorithm should be used.
In this way, even when the reading apparatus 100 is connected to a plurality of PCs using different OSs, operation data suitable for the connection destination PC can be output. The designation of the OS is not limited to manual operation. An OS operating on the connection destination PC may be detected by some means and automatically performed.

  In the above-described embodiment, an example in which the reading device 100 including the reading unit 131 outputs operation data has been described. However, the present invention is not limited to this. Further, although the example in which the reading device 100 that outputs the operation data is separate from the PC 200 that is the operation data output destination has been described, the present invention is not limited to this.

That is, like the operation data output device 100 ′ shown in FIG. 8, a data input unit 141 for inputting character string data is provided, and the character string data input from the data input unit 141 is used instead of the decoding result by the decoding unit 132. Based on this, operation data may be generated.
Character string data input to the data input unit 141 is received by the communication unit 241 that receives data from an external device, read by the reading unit 242 corresponding to the reading unit 131 and the decoding unit 132 of FIG. The data stored in advance in 243 and read from there can be considered.

Further, as shown in FIG. 8, the operation data output device 100 ′ can be provided as an integrated device with the control device 200 ′ that is the output destination of the operation data. In this case, it is conceivable that the operation data output device 100 ′ is configured as a module and is mounted on a substrate on which the main control unit 211 including a CPU is provided in the control device 200 ′. In this case, it is conceivable that the operation data output device 100 ′ supplies operation data to the CPU in the main control unit 241 via an internal bus.
It is also conceivable that the reading means 242 and the operation data output device 100 ′ are integrated into a module.

  In the above-described embodiment, an example in which Shift JIS is used as a character code of a multibyte character has been described. However, other arbitrary character codes such as GB18030, Big-5, EUC-KR, UTF-16, and UTF-8 are used. The present invention can also be applied to the case where is used.

When the OS is Windows, no matter which character code is used, the special key make → the multi-byte character code indicated by the character in the multi-byte character area is converted into a decimal number, and each digit of the value is obtained. With the operation data arranged in order from the highest digit to the lowest digit in order of the make and break of the key of the number on the keypad in order of the break of the special key, the multibyte character of the code indicated by the character in the multibyte character area Input can be directed to the service program. That is, operation data can be generated using the same algorithm without being conscious of which character code is used in the PC 200.
However, since the standard used for identifying the character code of a 1-byte character and the character code of a multi-byte character is different depending on the type of the character code, which character code is used is set in advance in the operation data output device.

Moreover, the program of this invention can be comprised as a program for making a computer perform the above-mentioned operation data output process. Such a program is stored in advance in a computer memory, and is also recorded on a non-volatile recording medium (memory) such as a CD-ROM or flexible disk, SRAM, EEPROM, memory card or the like as a recording medium. It can also be made available for download via the Internet. Each function described above can be realized by installing the program and causing the CPU to execute the program, or causing the CPU to acquire and execute the program from a memory or a download server.
In addition, the configurations and modifications described above can be applied in appropriate combinations within a consistent range.

As is apparent from the above description, according to the operation data output device, operation data output method and program of the present invention, a character string including a plurality of bytes can be easily processed as information on the keyboard in the information processing means. Can be provided.
Therefore, the operability of the control device can be improved by applying the present invention.
