PURPOSE:To prevent a selection error and a connection error of a transfer speed of a data, by transferring a data which has been generated from a sensor device, to a processing equipment, by use of a transfer control pulse which has been selected by a speed designating signal. CONSTITUTION:A transfer speed designating code A, B or C is set as an instruction code to a designation register 10 from a processing equipment. Also, a character code (f) for designating a transfer speed is set to the register 10 from a keyboard 5. Subsequently, the speed designating code A, B or C which has been set in advance is read out from a file device 6, and is set to the register 10. As a result, a discriminating circuit 11 checks contents of the register 10, and generates an output sigal a, b or c in accordance with the speed designating code A, B or C which has been set in the register 10. In this way, a transfer speed of a data is controlled by the processing equipments 4, 6, and the keyboard 5, and a selection error, etc. of the transfer speed are prevented. |
