Further, the transfer medium is an IC card. Further, a computer for creating data for performing numerical control, a transfer medium on which the data created by the computer is written, and data read from the transfer medium are read, and numerical control is performed in accordance with the read data. A data transfer control device having a controller that performs
The data is written to the transfer medium, and a command related to control in the computer is written at the head of the data, and the controller reads the data according to the command.

[0008] The controller is characterized in that it has a judging means for judging whether or not the transfer medium is inserted. Further, the determination means is operated by operating a switch provided in the controller and usually used for another purpose. Further, the controller, when the determination unit determines that the transfer medium is inserted,
Reading the command. Further, the transfer medium is an IC card. (Operation) In the present invention configured as described above, when data created by the computer is written to the transfer medium, a command related to control in the controller to which the data is transferred is written at the head of the data. , Commands and data are transferred to the controller using the transfer medium. And in the controller,
Data is read in accordance with the command written in the transfer medium, and thereafter, numerical control is performed in accordance with the read data.

As described above, since the data is read by the controller by reading the command written in the transfer medium, there is no need to perform an external operation when reading the data transferred from the computer.

Thereafter, the IC card 20 in which the data is written is inserted into the controller 30 and the power of the controller 30 is turned on again, or a switch used for another purpose in the controller 30 is operated. In the controller 30, the IC card 2
Data is read according to the command written to 0, the read data is stored in a memory provided in the controller 30, and numerical control is performed according to the read data. Here, the controller 30 determines whether the IC card 20 is inserted when the power is turned on again or when a switch used for another purpose is operated.
When it is determined that the card 20 is inserted, the command written in the IC card 20 is executed.
