PURPOSE:To make improvements in functionability, equilibration and stability, by coupling a pressure receiving plate, giving pushing force to a paper mounting tray of a paper feeding cassette, loosely within an interval between a pair of paper feeding opposite substances to oppositely come into contact with the pressure receiving plate, and installing it in a way of making its equilibrating motion attainable. CONSTITUTION:A paper feeding cassette 1 is provided with a tray 25 supporting the nearly first half part of paper in its bottom part, and this tray 25 is supported by a spring 34 so as to make it rotatable upward around a pin 33. In this case, a pressure receiving plate 11, giving pushing force to deliver the paper forward, is installed in this tray 25. This pressure receiving plate 11 has a hollow 12 in the central part, and a through hole 16 consisting of both opposed- form concave and convex parts 14 and 15 is formed on this bottom 13, while both upper and lower tension members 17 and 21 are installed with this through hole 16 held in between and coupled together with a screw 20. And, this screw 20 is screwable in any of tapped holes 27-29 formed in a hollow part 26. |
