Abstract
PURPOSE:To substantially equalize the machine size to the largest original document and make it compact by a light shield plate so as to prevent the exposure to light from the exposure opening when the outside region of the document tray on which the document is placed passes through the region of the exposure to light. CONSTITUTION:When document tray 2 is moved from position 2, home position on the machine body to position 2', the tray 2 moves to the position 2', with the light shield plate 25 immediately before the final end of its shift, namely, after the claw 24 of the tray 2 has been engaged with the claw 26 of the light shield plate 25. Therefore when the tray 2 is positioned at the final end position 2' from immediately before the position 2', the exposure opening 27 is completely covered by the light shield 25. The tray 2 starts to move from position 2' to position 2'' in order to start the exposure to light of the document, but the light shield 25 is always pulled by spring 28 to the left, hence the dxposure is made from the left end 2, because the left end 21 of the tray 2 is not hindered by the light shield. Accordingly, the size of the machine body can be substantially equalized to the largest document so that the machine body can be made compact.
