PURPOSE:To improve the efficiency of process of a host processor by sending detecting signals having predetermined discrimination codes added from a first processing unit to a second one and storing them in a memory when articles to be transferred reach the position of a sensor. CONSTITUTION:When an article A set to an inlet of a conveyer RA by a transfer control section 51, the signal S0 of a sensor 10 is recorded in a file 12 through a transmitting section 52 of a microcomputer 5 after a host processor 7 sets discrimination code I1 to the signal S0. When the article A passes by sensors 11, 40, 41, the signals S1, S40, S41 are respectively added to the discrimination codes I2, IB, I4 and recorded in the file 12. The articles B, C are similarly processed. When any abnormal happenings occur in a conveyer system 2 and causes thereof are removed to restore the conveyer to the original condition, the processor 7 cancels the passage record data in the file 12 and limits information amount to reduce a load on the processor 7. |
