Abstract

PURPOSE:To apply an IC card to a device which does not have the reader/writer of an exclusive IC card by setting a data transfer condition by means of the discrimination code of the data transfer condition of an object for data transfer which has previously been written in the IC card. CONSTITUTION:An identification code read means 7 reads the data transfer condition of the data transfer equipment 5 in a connection instrument 3, which has previously written in the IC card 1, and a data transfer condition setting means 9 sets the condition to its own condition. Thus, data can be effectively transmitted and received with the connection instrument 3 since the identification code of the data transfer condition written in the IC card 1 can set its own data transfer condition to be similar to that of the data transfer equipment 5 in the connection instrument 3. Thus, the IC card can be applied to various machines without attaching the reader/writer of the exclusive IC card for respective machines.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an IC card reader/writer.

(Prior art) For example, in the field of metal processing, NC devices and other
In order to exchange data with the device, a reader/writer for an external storage medium such as a floppy disk is sometimes provided.

In addition, in recent years, the superiority of IC cards as external storage media has been pointed out, and there has been a growing desire to attach IC card readers/writers to various devices and to exchange data between devices via IC cards. Ta.

(Problem to be Solved by the Invention) However, when each device is provided with an IC card reader/writer, there is no rotation, but for example, if an IC card reader/writer is installed in a machine that uses a floppy disk as an external storage medium, If you try to connect and transfer data,
There is a problem in that data transfer cannot be performed because the data transfer conditions of the IC card reader/writer and the data transfer device of the connected device as the data transfer target are different.

This includes the data transfer control method, baud rate, number of stop bits, presence or absence of parity, and
This is due to the fact that each manufacturer freely selects data transfer conditions, such as the type of transfer code, when manufacturing data transfer devices.

a. Control method (protocol) - Code control method - Line control method - Code/line mixed control method % - No parity - With parity (even) - With parity (odd) e. Transfer code - ISO code - EIA code・A S Cii code An example of a combination of these transfer conditions is shown in Company X's data transfer device: a. Line control type % type % C. Number of stop bits: 2 d. No parity e. EIA code...・(1
), and for seven companies, a. Code control method % formula % C. Number of stop bits 2 d. No parity e. Iso code ...... (2)
It becomes.

In factories, there are many machines that incorporate these data transfer devices into NCIII for the purpose of communicating internally and externally, so when trying to apply IC cards to each of these devices, it is difficult to The only option is to attach a dedicated IC card reader/writer to each device.

In particular, when creating NC data using automatic programming HM and applying this data to a predetermined NG device,
At present, there is a disadvantage that data cannot be transferred unless an IC card reader/writer is attached to the NCI device.

Therefore, the present invention provides an IC card for various machines without attaching a dedicated IC card reader/writer to each machine.
IC card reader that can apply cards/
The purpose is to provide writers.
