PURPOSE:To make modulation work ever so easy, by installing a memory circuit capable of modulating the memory time of a rejection signal through modulation for oscillating frequency in an oscillation circuit, in a device which rejects a defective article with a rejector by means of the rejection signal out of a checker judging the defective article. CONSTITUTION:A distance of a rejecting position II rejecting a defective article from a check position I checking its quality is set down to L and maximum dimensions corresponding to a conveying direction of the article to D, respectively, n progress counters 11-14 of the specified number being larger than these L and values are installed. Likewise, a symmetrization circuit 15, which symmetrizes each rejection signal (a) out of a checker and inputs it into each of these counters 11-14 as count starting signals (b)-(e), is installed. And, clock pulses out of an oscillation circuit 16 capable of modulating oscillating frequency are inputted into each clock pulse input terminal of these counters 11-14, and when a signal (g) is outputted from any of these counters 11-14, a rejecter 2 is constituted so as to be operated via a gate circuit G2.
