Abstract

PURPOSE:To enable data input processing without any key operation by providing a dedicated connector for a bar code reader, employing the same form with the input from a keyboard for the output of the bar code reader, and adding fixed data and sending the output of the bar code reader. CONSTITUTION:This personal computer is equipped with the main body part 1 of the lap-top personal computer, the bar code reader 2, the dedicated connector for bar code reader connection which meets the RS-232C standard, and the keyboard 4. Then a keyboard input emulating circuit 6 and a fixed data adding circuit 7 are reduced in size by IC implementation and constituted on one board together with the dedicated connector 3, and the board is inserted into a mounting slot provided to the main body part 1 and connected to a data output part 8 inside. Therefore, a bar code reader input function can be added when necessary. Consequently, easy input operation becomes possible without any program for output data input from the bar code reader 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a laptop personal computer, and particularly to a laptop personal computer in which the output of a barcode reader can be directly input without using a data input program.

[Conventional technology]

Conventionally, data input into a computer using a barcode reader has generally been performed via an interface of the R8-232C standard, and therefore it has been necessary to create a data input program. In addition, a conversion unit consisting of hardware that converts the output of a barcode reader into the same code as the number string from the keyboard has also been realized.
This conversion unit is inserted between the computer main body and the keyboard, and is used by connecting an output cable from a barcode reader to it.

[Problem to be solved by the invention]

Among the input methods using the conventional barcode reader described above, the method of inputting via the R8-232C standard interface requires the creation of a data input program, and the barcode contains JAN.

Since there are different types such as NW-7 and C0DE39, there is a drawback that it is not easy to create a program.

On the other hand, a conversion unit that converts using hardware has the disadvantage that it cannot be connected to a laptop-type personal computer in which the keyboard is built into the main body because it is inserted between the keyboard and the computer main body.

SUMMARY OF THE INVENTION An object of the present invention is to provide a laptop personal computer that can easily input the output from a barcode reader without using a data input program.

[Means to solve the problem]

The laptop personal computer of the present invention is equipped with a dedicated connector for connecting a barcode reader to the side of the main body having a keyboard, and converts the output from the barcode reader into a signal in the same format as the output from the keyboard. The main body includes a keyboard input emulation circuit and a fixed data addition circuit that adds fixed data corresponding to a specific key input to the output of the keyboard input emulation circuit.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of one embodiment of the present invention, in which 1 is the main body of a laptop personal computer, 2 is a barcode reader, and 3 is an R8-23 for connecting the barcode reader.
2C standard dedicated connector, 4 is a keyboard.

FIG. 2 is a block diagram showing the configuration of a data input section from a barcode reader. An input data recognition unit 5 that recognizes signals from the keyboard 4, and a keyboard input emulation circuit 6 that converts serial data from the barcode reader 2 into the same parallel data format as data from the keyboard.
, a fixed data adding circuit 7 that adds specific fixed data to the output thereof, and a data output section 8 that combines the outputs of the keyboard 4 and barcode reader 2 and sends them to the input control section 9 of the computer.

Data from the barcode reader 2 is sent to the keyboard input emulation circuit 6 via the R8-232C standard dedicated connector 3 as serial data (for example, serial code in JI38 unit system) of a number string (for example 123) corresponding to the barcode. Here, when the same number string is input from the keyboard 4, the data is converted into a parallel code in the same format (for example, JIS8 unit system) as the data output from the input data recognition unit 5.

The fixed data addition circuit 9 generates a parallel code (J
"0316" in the IS8 unit system is added after the number string (123) and sent to the input control section 9 via the data output section 8. As a result, input processing is performed every time data is read from the barcode reader 2 without operating the execution key.

On the other hand, seven inputs from the keyboard 4 are converted by the input data recognition section 5 into parallel codes used for processing inside the computer, and sent to the input control section 9 via the data output section 8. As a result, in the data output section 8, data input from the barcode reader 2 is handled in the same way as data input from the keyboard 1, and the output is sent to the input control section 9 without distinction. Note that, as a matter of course, input using the keyboard 4 and input using the barcode reader 2 can be used together.

The keyboard input emulation circuit 6 and fixed data addition circuit 7 are miniaturized by IC, etc., integrated into one board together with the dedicated connector 3, inserted into the mounting slot provided in the main body 1, and connected internally to the data output section 8. If you do this,
The configuration allows a barcode reader input function to be added if necessary.

In the above description, the code of the execution key is added as fixed data each time one piece of data is read from the barcode reader, but it may be added to each piece of data instead of each piece of data.

〔Effect of the invention〕

As explained in detail above, the present invention applies to ordinary R8-2
In addition to the 32C interface, it is equipped with a dedicated connector for the barcode reader, and uses a built-in circuit to output the output from the barcode reader in the same format as the input from the keyboard, with fixed data added, so it is not necessary to create a data input program. Data can be input directly from a barcode reader, and data input processing can be performed without key operations, which has the effect of simplifying data input. Therefore, it becomes possible to utilize the mobility of a laptop personal computer more effectively.
