To provide an inspection sorting system capable of preventing uninspected articles from being conveyed to a downstream device when the CPU of the control means of the inspection device has a runaway.

The inspection sorting system includes: conveyers 10 and 11; a weight sensor 65 which weighs the weight of the articles conveyed on the conveyer 11; a weight inspection device control part 61 which determines whether an article is good or defective based on the weighing result of the weight sensor 65, outputs the determination signal to show the determination result and outputs a pulse signal of a certain period by the CPU for carrying out the prescribed program; an abnormality detection circuit 62 which inputs a pulse signal, detects that the weight inspection device control part 61 is in the state of abnormality when the pulse signal is not input for a prescribed time longer than a certain period and stops the conveyers 10 and 11; and a sorting device 7 which inputs the determination signal from the weight inspection device control part 61 and excludes the articles determined as defective from the conveyer 12.
