Abstract: PURPOSE:To automatically perform error inspection by counting the numbers of white and black picture elements in the prescribed area of a document, and comparing them with first and second threshold values. CONSTITUTION:A comparator 202 performs binarization by comparing a prescribed threshold value with the output of a light receiver 136. When the number of white level picture elements of a counter 208 is less than a reference value, a digital comparator 212 decides that the setting of the threshold value in the binarization is not performed appropriately and a picture element to be binarized with a white level intrinsically is binarized with a black picture element accidentally, and the number of white picture elements amounts to a value less than the reference value. Meanwhile, when the number of black picture elements of a counter 210 is less than the reference value, a digital comparator 214 judges that the setting of the threshold value in the binarization at the comparator 202 is not performed appropriately, and the picture element to be binarized with the black level intrinsically is binarized with the white level accidentally, and the number of black picture elements amounts to the value less than the reference value.

IPC: B21B13/02
Filed: 1988-06-08
Abstract: PURPOSE:To reduce the load acting on a lift by recomposing an upper intermediate roll and an upper and a lower work roll from old rolls to new rolls on a truck and recomposing a lower intermediate roll by the lift from the old roll to the new roll. CONSTITUTION:The rolls obtained when a recomposition group of rolls are divided and mounted on a roll recomposition truck 8 are made an upper intermediate roll 4B and an upper and a lower roll 2B, 3B so that new and old rolls can be recomposed on this roll recomposition truck. Besides, the lower intermediate roll 5B is made so that it can be recomposed independently from an old roll to a new roll. Consequently, the roll recomposition truck need not be lifted by the lift, recomposition from old rolls to new rolls for the upper intermediate roll or the upper and the lower work rolls can be performed only by running them on a fixed floor. Since it is sufficient to lift only one lower intermediate roll the load of the lift can be reduced.
