The system generally denoted by reference numeral 100 has a host computer 110 for production management, and the host computer 110 has a database 120 that stores inspection reference information. The host computer 110 sends the inspection reference information in the database 120 to the inspection instruction form issuing PC 130.

The inspection instruction form issuing PC 130 issues an inspection instruction form 200 by the printer 132. In the inspection instruction form 200, reference data required for inspection of the completed vehicle P1 sent on the conveyor line 150 is printed as a barcode in the barcode display section 210.

The completed vehicle P1 receives the inspection instruction form 200 at the station S0 and is sent on the conveyor 150,
The first inspection station S1 is reached. The inspection process terminal device 160 installed in the first inspection station S1
A barcode 2 having a barcode reader 162 and printed in a barcode column 210 of the inspection instruction sheet 200
Read 11 In the barcode 211, reference data to be inspected in the first inspection process is written. The inspection reference data is set in the inspection process terminal device 160.

FIG. 2 is an explanatory diagram showing an inspection operation in the first inspection step. The inspection process terminal device 160 reads the barcode 211 of the inspection reference data of the inspection instruction form 200 with the barcode reader 162. For example, torque wrenches 165 and 166 are connected to the terminal device 160. The operator uses the torque wrenches 165 and 166 to inspect whether the bolts and nuts of the completed vehicle P1 are tightened with a predetermined torque.

The inspection result is displayed on a display or the like, sent to a bar code printer 164, and an inspection result label 220 is issued. This inspection result label 220
