PURPOSE: To exclude or rationalize the product inspection work in a post- process, by providing a bar-code detector, a judge and order circuit for judging the acceptability of a bar-code and an inferior product marking device operated by the signal of a main circuit or/and inferior product discharge device.
CONSTITUTION: A bar-code 7 is printed on a corrugated board sheet 6. The printed bar-code 7 is detected by a bar-code detection terminal 8 and the detection signal is transmitted to a bar code discriminator 9 to perform code confirmation as the bar code. Normal desired bar-code information is preliminarily inputted to a central control board 11 and a signal is transmitted to a judge and order circuit 10. Both of the bar-code signals received in the judge and order circuit 10 are compared and, if both signals coincide as the bar-code, a flag '0' is erected and, if both signals do not coincide, a flag '1' is erected. In the case of the flag '1', an order is issued to a marking device 12 and/or a discharge drive apparatus 13 and marking and discharge operations are respectively performed.
