Claims (1)

[Scope of utility model registration request] A digital copying machine that captures original images and copies them in a specified mode has an image memory with an image storage capacity for the number of originals to be copied, and copies two single-sided originals onto one sheet of transfer paper. mode, the images of each single-sided original are
A reading control unit that captures and stores it in the image memory, and a control unit that determines whether the number of originals to be stored in the image memory is an odd number when a mode of copying two single-sided originals onto one sheet of transfer paper is specified. When the number of originals to be checked is specified and the mode of copying two single-sided originals onto one sheet of transfer paper is specified, if the number of originals is determined to be an odd number by the number of originals detected, then The image is read from the last page of the original stored in the image memory and copied from the second side of the transfer paper, and the number of original sheets is determined to be an even number by the original sheet number detection section. For example, a digital copying machine characterized by comprising: a control unit that reads an image from the last page of a document stored in the image memory and causes copying to be performed from the first side of transfer paper.
