Abstract

PROBLEM TO BE SOLVED: To reduce man-hours in the case of transmission of a double side original and to reduce the cost of copying by allowing the facsimile equipment to be provided with a double side read mode where both sides of an original to be sent are read, the read image is sent sequentially in the order of the image on one side and then the image on the other side. SOLUTION: A double side read mode is selected, where both a front side read head 26a and a rear side read head 26b are operated based on an instruction from an operation section. In this case, the front side read head 26a reads an image on a front side Ma of an original M set to an original read section and the rear side read head 26b reads an image of a rear side Mb of the original M. Since the front side read head 26a and the rear side read head 26b are arranged in a feeding direction of the original M in this order, at first the front side read head 26a reads the front side Ma of the original M and then the rear side read head 26b reads the rear side Mb. Then page numbers are given to the images in the read order and stored in an image memory and the stored image is transmitted from a communication section.
