[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboard composite input device and a POS terminal device which can be connected to a POS terminal device or the like and have a function as a normal keyboard and a function as another input device.

[0002]

2. Description of the Related Art Today, in the distribution process of various products, POS
Various management is performed using (Point Of Sales).
Most conventional POS terminal devices are equipped with a bar code reader for reading the bar code printed on the product or on the packaging of the product, and a magnetic card reader for reading a magnetic card such as a credit card. ing. In addition, a keyboard is provided to input various data, and a keyboard interface is used for connecting the keyboard. The barcode reader and the magnetic card reader use another interface different from the keyboard interface, for example, RS-232C,
You are entering data.

If the keyboard and the bar code reader are treated as separate input devices and an input interface is provided separately, the structure of the information processing apparatus becomes complicated and the number of connection codes and the like increases.

Recently, it has been proposed to use other input devices such as a magnetic card reader by connecting them to a keyboard interface. In such a proposal, data output from another input device to the information processing device is also converted into a code corresponding to character data input from the keyboard. In the host information processing device, in order to distinguish the input data from the keyboard and the input data from other input devices, a special combination of keys is added to the input data from other input devices as an identification code. It is suggested to do so. For example, JP-A-5-8
No. 6023 discloses a prior art in which a magnetic card reader is connected to a keyboard interface to convert character data of a magnetic card into a code corresponding to an output code of the keyboard and output the code. Magnetic card data is
Since it should be kept confidential, it is suggested to add a backspace code so that the display program does not output it to the display device as it is when reading the storage contents stored in the magnetic card. Has been done.

[0005]

In a keyboard composite input device in which another input device is combined with a conventional keyboard, input data generated from an input device different from the keyboard is also converted into data representing a character generated from the keyboard. It is converted and output to an information processing device such as a POS terminal device as a host. As a result, the following problems occur.

Since the input data generated from the input device is converted into the code corresponding to the character generated from the keyboard and then output, the data size of the code of the input data becomes large. When data is transmitted through a general keyboard interface, the transfer speed of the keyboard interface is low, so the time required becomes longer and the processing speed of data from the keyboard composite input device decreases, Will be less efficient.

Since the input data generated from the input device is converted into a code corresponding to the character generated from the keyboard and is output, in the information processing apparatus as the host, the input data is the input data corresponding to the character from the keyboard. It is not possible to accurately determine whether there is data or input data from an input device other than the keyboard. Although it has been proposed to use a specific combination of key code strings as an identification code for input data from an input device different from the keyboard,
Since the identification code itself can be generated by an input operation on the keyboard, it is impossible to accurately determine the input device.

In a keyboard composite input device having a magnetic card reader and the like together with a keyboard, read data from a magnetic card, which should be kept confidential, is converted into a code indicating the same character as the keyboard and is output. The data stored on the card may be easily viewable. JP 6-3
In the prior art of 01825, a backspace code is added after the read data from the magnetic card, and even if the read data is displayed, it is erased by the backspace code and is not displayed. However, if you write a program that sees the key input event as it is, erasing will not occur even if you insert the backspace, and only the code corresponding to the backspace will be displayed, making it easy to read the data on the magnetic card. It will be possible to see.

An object of the present invention is to provide a keyboard composite input device and a POS terminal device capable of promptly inputting data, easily distinguishable from a character code input from a keyboard, and easy to maintain confidentiality. It is to be.

Processing can be performed. Also, since the input data different from the code data representing the character corresponding to the key is output, the input data generated by the input operation to the input device can be easily distinguished from the code data generated by the input operation on the keyboard. it can. Further, the keyboard interface of the information processing device on the host side to which the keyboard composite input device is connected is limited in the range of codes that can be input. Therefore, although it may be impossible to directly transmit the input data generated from the input device, the input data output means performs an operation so that the input data generated from the input device falls within the limit range. As a result, it is possible to easily convert the input data into the output data that can be input on the host side, and input the input data from the input device to the information processing apparatus on the host side as with the keyboard. As a result of the operation, a code indicating the operation is output, so that it can be recognized that the input is from the input device.

Further, in the present invention, the key code output means includes a make code generated at the time of pressing one key and a break code generated at the time of releasing the key and having a certain relationship with the make code. Is output as a pair, and the input data output means outputs a code indicating the type of the input device and the input data itself.

According to the present invention, the key code output means outputs a make code generated when one key is pressed and a break code generated when the key is released in pairs. Since the input data output means outputs a code indicating the type of the input device and the input data itself, it is possible to easily determine whether the keyboard or the input device is operated from the output code.

Further, in the present invention, the input data output means, when outputting the input data itself, also includes additional data having the same relationship with the input data as the pair of the make code and the break code. It is characterized by outputting.

According to the invention, the input data output means is
When the input data itself is output, since additional data having the same relationship as the pair of the make code and the break code from the key code output means is also output to the input data, the keyboard composite input device is connected. In the information processing device on the host side, when the input data is not a pair of break code and make code, it eliminates the possibility of erroneously determining that there is something wrong with the keyboard and transfers data normally. be able to.

The POS keyboard composite device 2 of this embodiment transmits input data in a transmission format as described below.

First, in order to identify whether the transmission data of the POS keyboard composite device 2 is magnetic card read data, keyboard data, or mode switch data, an identification code is added to the beginning of each data. Codes not included in the output code of the keyboard device unit 15 are set as the identification codes of the magnetic card read data and the mode switch data, respectively. The output code of the keyboard device unit 15 is ScanCodeSet 1 as shown in FIGS. 11 to 13, which has the same data format as the standard keyboard. Therefore, no identification code is required for the keyboard. Use keyboard scan code type 1 (ScanCodeSet 1). FIG. 14 shows an example of the device identification code.

FIG. 15 shows a format when the magnetic card read data is transmitted from the magnetic card reader unit 15, and FIG. 16 shows an error code transmission format when the magnetic card cannot be read normally. .
The first byte of FIG. 15 is the magnetic card data head identification code of FIG. The card type of the second byte is shown in FIG.
The types of standards for magnetic cards are shown below. The 3rd byte shows the character data of the actual card. The character data of the card will be described later. The 4th byte is the magnetic card data end identification code of FIG. The first byte of FIG. 16 is the magnetic card error data head identification code of FIG. The error status in the second byte includes the error information shown in FIG. The third byte is a code corresponding to a break code, with the code indicating the error status of the second byte being the make code. The transmission format of the magnetic card read error code shown in FIG. 16 is a fixed size format, and since it is sufficient to identify only the head code, the end identification code is not required.

FIG. 19 shows the format of the mode switch position information data from the mode switch section 17.
The first byte is the mode switch data start identification code in FIG. The second byte is the value of the mode switch position data (1 to 8) shown in FIG. 20 or the position unknown code “30h”. The position unknown code is provided for the purpose of notifying the host side that the position of the key type key 20 is at an intermediate position between the positions or that the position of the key type key 20 cannot be detected and detected due to some trouble. . The mode switch position data has a value of 1 to 8 and indicates the position to which the key type key 20 faces according to FIG.

Finally, in the POS keyboard composite device 2 of the present embodiment, regarding the transmission data when the magnetic data as shown in FIG. 8 read by the magnetic card reader unit 15 is transmitted via the keyboard I / F 3. explain. As described above, the character codes of the JBA standard magnetic card are "20h" to "7Fh" and "0Eh" and "0Fh" indicating SO and SI, respectively. These codes are used as a standard as shown in FIG.
8 calculates and converts it into an output code and sends it to the host side.

FIG. 23 shows an example of data when the data of FIG. 8 is transmitted to the host side in the POS keyboard composite device 2 of this embodiment. The character code "31h" in the first byte and the character code "3D" in the second byte
“H” indicates the characters “1” and “=” of the magnetic card data, which is within the range of 20h to 4Fh shown in FIG. 22, and therefore is transmitted to the host side as it is. Character code "54h" of the character "T" in the 3rd byte
Is within the range of 50h to 7Fh shown in FIG.
Subtract 30h and send as "24h". In the case of subtracting 30h, "01
"h" code is added.

The character code of the character "a" at the 4th byte is "61h".
h ”. Since 30h is subtracted even at the third byte, it is not necessary to add "01h" to the beginning for identification again. Similarly, the characters "r" and "o" at the 5th and 6th bytes are "72h" and "6Fh".
30h is subtracted from the character code of "42h",
It is transmitted as a code of "3Fh". Also in this case, since the previous code is subtracting 30h, it is not necessary to add the identification code "01h".

Since the character code of the last character "." Is "34h", which is in the range of 20h to 4Fh shown in FIG. 22, it is transmitted to the host side as it is. Therefore, the entire code to be transmitted is "31h, 3Dh, 0
1h, 24h, 31h, 42h, 3Fh, 02h, 34
h ”, and the amount of data when transmitting through the keyboard I / F 3 is 9 bytes. If the data communication speed is 2 ms per byte, it can be transmitted in a required time of 18 ms, and the data transmission amount is obviously reduced and the time required is shortened compared with the case of converting to a key code and transmitting. To be done.

FIG. 24 shows, as another embodiment of the present invention, a case where a key corresponding to the character code at the time of transmission in FIG. 23 is used as a make code and a corresponding break code is added. The keyboard I / F 3 normally operates on the assumption that a standard keyboard is connected.
When a key code similar to that of a normal keyboard is not input, if the input code is monitored and checked, the code shown in FIG. 23 may not be accepted. The purpose of this embodiment is to prevent this. The data in FIG. 24 is the amount of data when it is transmitted through the keyboard I / F 3, and is 18 bytes. When the data communication speed is 2 ms per byte, the required time is 36 ms. Compared with the case of converting to a key code and sending,
Clearly, the amount of data transmitted is reduced and the time required is shortened.

The above is a description of the data format used in the POS keyboard composite device 2 of the present embodiment. Next, as still another embodiment of the present invention, FIG.
27 to 27, an example of a control procedure regarding the POS keyboard composite device 2 in the case where the POS terminal device 1 performs sales processing of the POS system and the like will be shown.

In step s1, the POS keyboard composite device 2 or the standard OADG (Open Architect) is used.
ure Developers Group) A keyboard device is connected to the POS terminal device 1 serving as a host via the keyboard I / F 3 to configure a POS system, and the system is powered on. In step s2, the basic guarantee test is executed by the POS keyboard composite device 2 or the standard OADG device.

The basic assurance test is based on the BAT (Basic Assura
Also called "nce Test", the control unit in the keyboard sequentially tests predetermined inspection items and outputs a normal completion code when the inspection is completed normally. If the test finds an error, it outputs an error completion code. In the OADG keyboard device specification, the normal completion code is AAh and the abnormal completion code is “FCh”. The POS keyboard composite device 2 of the present embodiment outputs the BAT normal completion code and then outputs the code “E0h” for identifying the POS keyboard composite device 2 within a predetermined time. The predetermined time is, for example, 25 ms. BAT is performed at the time when the power supply voltage is supplied to the device or when the device is connected to the keyboard I / F 3 on the host side which is already powered on.

In step s3, it is determined whether or not BAT has been completed normally. If it is completed normally, the BAT normal completion code "AAh" is transmitted in step s4, and if it is the POS keyboard composite device 2, then the identification code "E0h" is sent to the POS terminal device 1 on the host side. Send. In step s5, the POS terminal device 1 on the host side receives the BAT normal completion code “AAh”. In step s6, the POS terminal device 1 measures the waiting time with a timer. In step s7, the waiting time is 10
It is determined whether or not it is 0 ms or more. The waiting time is, for example, 100 ms in consideration of a margin from the predetermined time of 25 ms. When the waiting time is less than 100 ms, in step s8, the POS terminal device 1 sets P
Identification code "E0h" of OS keyboard composite device 2
Is received. If not received, the process returns to step s6 to continue waiting for reception.

The maximum waiting time in step s7 is 100.
If ms or more, in step s9, the POS terminal device 1
Determines that a standard OADG keyboard device, not the POS keyboard composite device 2, is connected to the keyboard I / F 3, and executes initialization processing for the standard keyboard device. When the identification code “E0h” is received in step s8, the POS is performed in step s10.
The terminal device 1 determines that the POS keyboard composite device 2 is connected to the keyboard I / F 3, and executes the initialization process for the POS keyboard composite device 2.

If the BAT result is abnormal completion in step s3, the POS keyboard composite device 2 or the standard OADG keyboard device is
BAT abnormal completion code F on the POS terminal 1 on the host side
Send 0h. In step s12, the POS on the host side
The terminal device 1 receives the BAT abnormality completion code, determines that there is an abnormality in the POS keyboard composite device 2 or the standard OADG keyboard device in step s13, warns the user of the abnormality, performs predetermined abnormality processing, and performs control. Finish the procedure.

After the initialization processing for the POS keyboard composite device 2 is executed in step s10, step s
At 14, the process waits for the data transmitted from the device connected to the keyboard I / F 3 to be received. Step s
If there is no transmission data in 15, the reception waiting in step s14 is repeated. If there is transmission data in step s15,
In step s16, data is received from the data receiving port of the keyboard I / F3. In step s17, it is determined from which device the POS terminal device 1 on the host side is the output data based on the value of the received data.

If the head of the received data is the magnetic card data head identification code "E2h" shown in FIG. 14, the POS terminal device 1 on the host side at step s18, the magnetic card data end identification code "E3h" shown in FIG. Until data can be received, data reception is continued and all magnetic card data is received. If all the data shown as the magnetic card data format in FIG. 15 can be received, in step s19, the received data is returned to the original magnetic card data for coding, and the POS application processes it as magnetic card input data. When the data from the magnetic card is received via the keyboard I / F3, the recorded contents of the magnetic card cannot be seen even if it is displayed as it is. The data change is performed by a simple calculation, and the processing load is small and the required time is short as compared with the case of converting to the key code.

If the received data is the magnetic card read error identification code "E4h" shown in FIG. 14 in step s17, data of a fixed size as shown in FIG. 16 is received in step s20. This size is, for example, 3 bytes. The POS terminal device 1 on the host side that has received the error code handles it as a reception error in the POS application. If the received data is the mode switch data start identification code "E6h" shown in FIG. 14 in step s17, data of a fixed size as shown in FIG. 19 is received in step s21. This size is, for example, 3 bytes. In step s22, the POS terminal device 1 on the host side processes the mode switch data with the POS application.

If the received data is the BAT normal completion code "AAh" in step s17, step s23.
Then, it is determined that the POS keyboard composite device 2 connected to the keyboard I / F 3 is disconnected, the POS keyboard composite device 2 is connected again, or the standard keyboard device is connected, and the process returns to step s6.

If the received data is the BAT abnormal completion code "FCh" in step s17, step s24
Then, the POS keyboard composite device 2 connected to the keyboard I / F 3 was disconnected, and the POS keyboard composite device 2 or the standard keyboard device was connected again, but the BAT result of the connected device was abnormal. If so, the process proceeds to the warning / abnormality process for the user in step s13. It is also possible to perform processing that warns the user that the device has transitioned to the state of “connected → not connected → connected”.

If it is determined in step s17 that the received data is not the above-mentioned code, in step s25 the device identification code and the BAT completion code due to disconnection / connection of the device connection, not the input based on the keyboard operation, are input. Judge as data or keyboard device data such as a standard command from the keyboard to the host side other than those mentioned above. In step s26,
The commands from the keyboard to the POS system are processed in the same way as from the standard keyboard, and the keyboard input data is exactly the same as the input data from the standard keyboard.
Process with a POS application or the like. Step s1
9. When step s22 or step s26 is completed, the process returns to step s14 and waits for the next received data.

In step s9, when the POS terminal 1 determines that the standard keyboard is connected and executes the initialization process, it waits for data reception from the device in step s27, and if there is data in step s28. , Data is received in step s29. In step s30, the processing is divided according to the value of the received data.

If the received data in step s30 is the BAT normal completion code "AAh", in step s31,
The host side determines that the connected keyboard device is disconnected and that the keyboard device is connected again, and the process returns to step s6. It is also possible to perform processing that warns the user that the state of “connected → not connected → connected” has transitioned.

If the received data at step s30 is the BAT abnormal completion code "FCh", at step s32,
Although the connected keyboard device is disconnected and the keyboard device or POS keyboard composite device 2 is connected again, the host side determines that the BAT result after the connection is abnormal, and then step s1
Move to the warning / abnormality processing to the user of 3. The device is
It is also possible to perform processing that warns the user that the state of “connected → not connected → connected” has transitioned.

If the received data in step s30 is not the BAT completion code, it is judged that it is input data to the keyboard or a standard command from the keyboard to the system, and the command from the keyboard to the system is executed in step s33. The keyboard input data
It is processed by an OS application or the like. After the process is complete,

As described above, according to the present invention, in a keyboard composite input device in which a keyboard and an input device different from the keyboard are combined, code data representing a character corresponding to an operation on the keyboard and the input data generated from the input device. The input data to be input can be input to the information processing device from the same keyboard interface. Since the input data does not need to be converted into character code data as it is generated from the input device, quick input is possible, and the character and the input data can be easily distinguished. Even if the data input from the input device requires confidentiality, it can be processed separately from the code data from the keyboard so that it cannot be displayed as easily as the data from the keyboard. Even if there is a limit to the range of data that can be input with the keyboard interface, the code that indicates that the operation was performed so that the input data from the input device falls within the range and the operation result And can be input via the keyboard interface.

According to the present invention, the code corresponding to the input operation on the keyboard is generated as a pair of the make code and the break code, and the code corresponding to the input operation on the input device indicates the type of the input device. Since the indicated code and the input data itself are output, the data from the keyboard and the data from the input device can be easily identified.

Further, according to the present invention, the data from the input device output by the data output means is additionally output with the additional code having the same relationship as the pair of the break code and the make code from the keyboard. Even when a pair of a make code and a break code is required for the input processing on the side, the input data from the input device can be treated as normal data.

Further, according to the present invention, the key code output means and the input data output means execute the basic guarantee test under predetermined conditions and output the code according to the test result, and the input data output means further continues for a fixed time. Since the input device identification code is output later, if a basic assurance test is executed on the information processing device on the host side, it is possible to easily determine whether the keyboard composite input device is connected or a normal keyboard is connected. .

Further, according to the present invention, when the power is turned on, the basic guarantee test is executed through the keyboard interface, and it is determined whether the keyboard or the keyboard composite input device is connected according to the output code. Since the data input from the keyboard input interface is processed according to the determination result, appropriate processing can be performed according to the data.

Further, according to the present invention, it is possible to judge whether the input device connected to the keyboard interface is the keyboard or the keyboard composite input device even when the POS terminal device is operating. Appropriate data processing can be performed even if the keyboard and the keyboard composite input device are used while being operated.
