<p>PURPOSE:To enable changeover from a position for a paper feeding casette to a position for a mass paper supplying device without detaching a bottom plate life lever by displacing and fixing the lift lever from the position for the paper feeding casette to the position for the mass paper supplying device. CONSTITUTION:A lift lever 2 is attached to a shaft 21 with a stepped screw 22 and moved up and down by turning the shaft 21, and when the lever 2 is lifted up, a bottom plate 23 is lifted up to convey record paper 4 with a contacted pick up roller 3. On the bottom plate lift lever 2, push balls 2a, 2b are provided respectively, and on the shaft 21, a through hole 21a fitted to the push balls is provided. When a paper feeding casette is used, the push ball 2a is inserted in the through hole 21a to fix the lever 2 in a paper feeding casette position, and when a mass paper supplying device is used, the push ball 2b is inserted in the through-hole 21a and fixed in a release condition. Hence at the time of changeover, the lever 2 can be turned and fixed without detaching the screw 22, and thereby operability can be improved and the loss of the lever 2 or the screw 22 can be eliminated.</p> |
