Abstract: PURPOSE: To stabilize the contact pressure of a piled sheet layer on a feeding roller by providing a rotation supporting point in the center of the length in the sheet- feeding direction and also providing the center of gravity of a sheet-storing box at the back of the supporting point.  
     CONSTITUTION: A rotation supporting point 13 is provided in the center of the length in the sheet-feeding direction. And a box 14 for storing a piled sheet layer 2 is positioned so that the center of gravity of the box itself accords to the rotation supporting point 13. Moreover, by adding a handle 17 or a weight 18 to the back of the sheet-storing box 14, the center of gravity of the box is shifted to the back of the rotation supporting point 13, pressing the piled sheet layer 2 to a paper-feeding roller 3. This can be expressed as the following formula: F×l 2 =W×l 1 ; F= l 1 /l 2 ×W, where the contact pressure is F and the weight is W. In this way, by setting the center of gravity of the sheet-storing box at the back of the rotation supporting point in the sheet-feeding direction, the value of F becomes constantly fixed and thus the contact pressure of the piled sheet layer 2 on the paper-feeding roller 3 can be applied in a stable manner.
