PURPOSE:To achieve selective feeding of sheet paper by moving a sheet paper containing means having more than predetermined stages obliquely upward by means of an elevatable moving means then contacting with a paper discharge means through function of a removable fluid telescopic means. CONSTITUTION:Upon selection of a paper tray 2 of free size by means of a selection switch, a motor 24 will function to drive an air pump 23 while to exchange a three-way valve 22 and to lift an elevating member 26 to the uppermost position through a removable telescopic mechanism 11 and stop. Thereafter, a motor 10 will rotate a cam 8 to the right and to lower a pull rod 6 thus to accumulate the trays. The solenoid 7 below the selected tray 2 is de- energized while the motor 10 will rotate to the left to lift the pull rod 6 to the opposite side of paper discharge together with the tray above the selected stage thus to expose the selected tray 2. Thereafter, the three-way valve 22 is exchanged to lower the elevating member 26 to the selected tray position and contact with the paper discharge roll 31. The discharged paper is fed through carry rolls 42-45 to the paper receiving section 48 of copy machine 47. |
