Abstract

PURPOSE:To shorten the distance by which a form is conveyed individually and prevent paper from jamming by moving one-surface copied forms stored in an intermediate cassette to a paper feeding part for double-face copying together with the cassette by using a moving device. CONSTITUTION:The intermediate cassette 17 is provided while allowed to reciprocate between the position where one-surface copied forms are received and a cassette cradle 18 at the paper feeding part by the moving device 20. A chain 23 driven by the sprocket 24 of the moving device 20 is linked to an end part of the cassette 17. A form from the paper feed cassette 1 is passed under a branch pawl 7 after one-surface copying operation and then stacked in the intermediate cassette (17). The cassette is moved to the cradle 18 by the moving device 20 after a specific number of sheets are copied, and the sheets are discharged into a discharge tray 9 after reverse-surface copying operation. Consequently, the distance by which a one-surface copied form is conveyed is shortened and an accident such as paper jamming is prevented.

Since no transport is required, the mechanism for transporting the transport can be simplified. Therefore, when the copying machine is returned to the paper receiving position of the intermediate cassette, a wide space is formed at the bottom of the copying machine, and even if a failure occurs, work can be done through that space.

さらに、用紙を単独で搬送する距離を短縮できるために
