摘要： An apparatus 1 for determining a kind of a steel material detects a spark pixel from a color picked-up image 2 of a spark 19 produced when a steel material 18 is ground, and detects a pixel, in which the density of any one color component for judgment selected from among RGB color components is low, as a low-density pixel from the spark pixels. The apparatus 1 determines that the steel material is a steel material consisting of the high-strength steel if the ratio of the total number of low-density pixels to the total number of spark pixels is not lower than a threshold value for judgment, and determines that the steel material is a steel material consisting of the ordinary steel if the ratio is lower than the threshold value for judgment.

摘要： A chopper table comprises table bodies for guiding a signature transported by transport belts, and a pair of inlet guides for guiding the signature pushed in by a chopper blade. The table bodies are detachably supported on chopper frames, and the inlet guides are detachably supported on the chopper frames via brackets. The chopper table improves the returnability of the table body and inlet guide when they are removed at the time of a paper jam or replacement of the transport belt, and can easily adjust the gap of a slit between the inlet guides.
