<p>PURPOSE:To confirm paper size on the paper-feed side easily by providing a cover for a paper feed cassette which is rotationally moved to allow paper feed with feed ports at both right and left ends to be alternatively blocked and the other to be opened and providing both sides of the cover with indication faces which indicate the paper size on the respective open and feed sides. CONSTITUTION:When a cover 7 is rotationally moved to either one side using supporting points 6 as an axis, the cover 7 alternatively blocks one feed port and opens the other feed port. At this time, paper size on the open side always appears on the surface 9 of the cover 7. An insertion preventing member 8 in the vicinity of the tip of the cover 7 is protruded from the cover 7 to prevent insertion into an image forming device on the side of the feed port, alternatively blocked by the cover 7. On the contrary, there is no cover 7 on the open side and therefore no insertion preventing device 8 in a protruded form, thus to allow insertion.</p> |
