PURPOSE:To achieve selective feeding of required number of sheet paper by moving the section higher than predetermined stage obliquely upward through moving means to expose a predetermined number of sheet containing means then elevating the paper discharge means through pantograph means. CONSTITUTION:Upon selection of paper tray 2 of free size through a selection switch, a motor 10 will rotate forward to turn on the clutch C2 to lift an elevatable member 13 to the highest position through pantograph means 12. Then, clutch C1 is turned on to rotate a cam 8 to the right thus to lower a pull rod 6 to the paper discharge side to accumulate all trays and to turn off the solenoid 7 below the selected tray 2. Thereafter, the motor 10 is rotated reversely to move the pull rod 6 upward to counter-discharge side together with the trays above the selected tray 2 thus to expose the selected tray 2. Then clutch C2 is turned on to lower an elevatable member 14 to the position facing with the selected tray thus to feed the sheet paper 1 one by one through sheet paper carry means 26 to the paper receiving section 37 of copy machine 36. |
