Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for reading data recorded on a data carrier and loading the data into a computer.

[0002]

2. Description of the Related Art For writing / reading between a data carrier and a read / write device by a non-contact method, for example, the one disclosed in Japanese Patent Laid-Open No. 62-8281 is known. A technology for capturing data from outside the computer represented by this technology is formed by including a data carrier storing data, a reader (read device) / writer (write device), and a computer main body. The reader reads the data on the data carrier, sends the data to the computer body, and the computer body uses the data to process the data. If the data carrier is not capable of writing data, the data is a one-way flow from the data carrier to the computer body, but if the data carrier is a data carrier on which computer-processed data can be written, Data is transmitted from the computer to the writer, and the writer writes data to the data carrier. In any case, the transmission function referred to here is generally called a “communication function”.

[0003] Such a technique is used in a production site such as an automated production line or in the processing of patient charts in hospitals. As a data carrier, an individual such as a punched card or a printed matter printed with a bar code is used. A read-only ID tag with an identification display unit,
There is a readable / writable device such as a memory card or a magnetic card incorporating an IC chip or an LSI chip.

[0004]

In the above-mentioned prior art, a communication function for transmitting data read by a reader to a computer main body or transmitting data from a computer main body to a writer is a data processing function in the computer main body. At the same time, application software running on the operating system of the computer itself is running. Therefore, in this kind of application software,
In addition to the data processing section that performs the intended original processing (for example, processing status management at the production site and data storage processing in medical records, etc.), it reads data carrier information or writes new information to the data carrier. Therefore, it is necessary to always provide a communication processing unit for processing a communication operation performed between the reader / writer and the computer main body.

[0005] For this reason, in spite of the fact that the hardware configuration of the reader / writer and the computer main body are the same, if the type of data to be handled and the data processing method are different, each time the data processing function is added to the target data processing function. In addition, the application software must be individually created in such a manner as to always have a communication function or a data transmission function, which places a heavy burden on the software creator.

As a technique for solving this problem, Japanese Patent Application No. Hei.
Japanese Patent Application No. 1-043132, Japanese Patent Application No. 11-244526, and Japanese Patent Application No. 2000-020696 are known. However, in these methods, since the data of the data carrier is stored in a file or stored in a shared memory, the data can be read and written relatively easily, and it is difficult to protect the secret of the data contents. The present invention has been made in view of the above points, and in a technology for performing predetermined processing after reading data recorded on a data carrier and taking it into a computer main body, a communication function and a data processing function are separated. Another object of the present invention is to not only reduce the burden on software creators but also protect the confidentiality of data contents.

Any non-contact type that reads in non-contact can be used. A “write device” is a device (writer) that can write data on a data carrier. Like the read device, the structure differs depending on the type of data to be written, and may be either a contact type or a non-contact type. Note that the read device and the write device may be separate devices, but if a reader / writer having both functions is used, it is preferable that only one transmitting means is used.

Since the contents of the predetermined data transfer procedure are not normally disclosed simply by introducing an operating system or device driver software provided separately, the confidentiality of input data can be easily achieved. .
Therefore, when creating predetermined application software, it is necessary to disclose information on a predetermined data transfer procedure for receiving input data when introducing a computer, operating system, or separately provided device driver software. Must, but by doing so, only the data processing unit needs to be created. In this manner, it is not necessary to create a dedicated communication processing unit for each application software, and the secrecy of input data is ensured.
