Abstract:
PURPOSE:To prevent the omission of a fine line by sending the OR of picture information read at the reading position of a stored sensor and the picture information. CONSTITUTION:After a picture signal for one line in a main scanning direction is binarized by a sensor 1, it is inputted to a line buffer part 3 bit by bit, a control part 5 controls a stepping motor driving circuit part 7, drives a stepping motor by one step, and sends an original by a half of the read width of the sensor 1. When the picture information of the next main scanning line is inputted from the sensor 1 at such a position, a switch 6 is changed over to a (b) side. When the binarization picture information of the current main scanning line is inputted to a logical processing part 4, it is synchronized, and the binarization information of the previous main scanning line is inputted from a line buffer part 3 to the logical processing part 4, and the binarization picture information of the OR is outputted.
