Abstract

Abstract PURPOSE:To reduce the number of data to be transferred, by outputting a data for controlling a scanning distance of a scanning means by a microcomputer, and also making a scanning distance in case of variable magnification correspond to that in case of unmagnification. CONSTITUTION:To a control microcomputer mu1, a copy key signal, a ten key signal, a cassette size signal from a variable magnification command signal 26, etc. are inputted, control signals of copy start, a scanning distance, various displays, etc. are outputted, and a scanning distance controlling data, a repeat controlling data, a stopping data, etc. are sent and received between said microcomputer and a sequence microcomputer mu2. Connecting lines (a), (b) between both the computers are used for sending a scanning data, a variable magnification factor data, etc. are sent by other lines (c), (d), and 4 bits are outputted in parallel as a whole. Also, desired magnification consists of 3 ways such as unmagnification, M1 and M2 so that the scanning distance is limited to 3 ways, and number of data to be transferred is reduced.
