Abstract

PURPOSE:To enable data communication between the different types of devices by receiving the data of a first code system, converting them to the data of a second code system and transmitting the converted data. CONSTITUTION:Data 8 of a JIS code are received from a keyboard 1, which generates the data of the JIS code, to a reception part 3 of a code converting device 2. The received data are passed through a data bus 6 and converted into an ASCII code by a data conversion part 4. The converted data are transmitted through the data bus 6 to a data transmission part 5. The data transmission part 5 transmits ASCII code data 9 to an information processor 7. The information processor 7 recognizes the ASCII code and can process the data. Thus, since this device is connected between the devices of the different code systems, data communication can be executed between the different types of devices.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a code conversion device used for one-to-one device data communication.

0002

2. Description of the Related Art In conventional data transmission and reception of this type, the code format of data transmitted from the other party is determined in advance.

For example, when data is sent from the keyboard 1 in JIS code as shown in FIG. data is received and processed.

0004

[Problems to be Solved by the Invention] In conventional data communication, data may be incorrectly received and processed simply by a difference in the code system between communicating devices, resulting in problems with data reliability. Ta.

[0005]

[Means for Solving the Problems] A code conversion device of the present invention includes a data receiving section that receives data in a first coding system, and converts the data received by the data receiving section into data in a second coding system. and a data transmitter that transmits data whose code system has been converted by the data converter to the outside.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a diagram showing a code conversion device 2 according to an embodiment of the present invention connected between a keyboard 1 and an information processing device 7. As shown in FIG.

JIS code data 8 is received by the receiving section 3 of the code conversion device 2 from the keyboard 1 which generates JIS code data. The received data passes through the data bus 6 and is converted into an ASCII code by the code converter 4. The converted data passes through the data bus 6 and is sent to the data transmitter 5. The data transmitter 5 is an AS
The CII code data 9 is transmitted to the information processing device 7. The information processing device 7 can recognize the ASCII code and perform data processing.

[0009]

As described above, the present invention has the advantage that data communication between different types of devices can be performed by connecting devices with different code systems.

[Brief explanation of drawings]

FIG. 1 is a block diagram showing one embodiment of the present invention.

FIG. 2 is a block diagram illustrating communication between two conventional devices.
