PURPOSE:To execute both-face copying without requiring an exclusive copying machine for both-face copying by providing an auxiliary machine body containing a carrying direction switching plate, a leading-in roller, a return belt, etc., so as to be freely attachable and detachable to and from a copying machine body, and making the length of the return belt flexible. CONSTITUTION:An auxiliary machine body 30 containing a carrying direction switching plate 27, leading-in rollers 29, 29', a return belt 35, etc. is installed so as to be freely attachable and detachable to and from the lower part of a copying machine body 1, and also the return belt 35 is constituted so as to be flexible in accordance with long or short length of the horizontal direction extending from a front wall 1a to a rear wall 1b of the copying machine body 1. Accordingly, a copying paper sheet which has copied a picture on one face by the copying machine body 1 is guided to the carrying direction switching plate 27 of the auxiliary machine body 30, led to inversion rollers 42, 42' from the return belt 35, fed into the second feed paper cassette 4 by forward and backward rotations of the inversion rollers 42, 42', and copying to one face on which a picture is not transferred yet is executed. |
