Claims (1)

[Scope of Claim for Utility Model Registration] (1) In a copying machine that performs the printing process by stacking original sheets of various shapes and sizes with the leading edge of the photosensitive sheet leading the original sheet by a predetermined distance or more, the printing process A guiding direction changing member provided at the exit of the means, a turning guide member provided following the guiding direction changing member for conveying the photosensitive sheet to a developing process, and confirmation of passage of the photosensitive sheet at the turning guide member. at least two catch sensors for transporting the photosensitive sheet to the turning guide, and actuating means for actuating the guiding direction changing member in response to the outputs of the catch sensors, the guiding direction changing member normally being used for transporting the photosensitive sheet to the turning guide. The actuating means is movable between a first position and a second position in which the original sheet is conveyed to the original tray side, and the actuating means is movable between the guiding direction changing means and the guiding direction changing means in response to the detection of passage of the photosensitive sheet by the catch sensor. An automatic document ejecting device for a photosensitive sheet copying machine, characterized in that the device operates to switch the document to the second position. (2) The automatic discharging device according to item 1, wherein the copying machine supplies the photosensitive sheet by means of continuous sheet cutting means.
