PROBLEM TO BE SOLVED: To stably feed various recording sheets without generating a mis-feed and a double feed, by arranging a center separation plate in the center and both ends separation plate at both end parts in paper feed direction in orthogonal direction with a varied gradient, in a paper feed direction tip end part of the recording sheets. SOLUTION: Recording sheets with its both sides regulated by recording sheets guides 12 in a recording sheet stacker 11, is layered with the center serving as the reference. The layered recording sheets are fed to be separated into one sheet by a function of a center separation plate 15, both ends separation plate 16, and pickup rollers 13. A gradient of the separation plates 15, 16 is required to be small for preventing so-called mis-feed of no-feeding in thick sheets such as post cards while causing increase of double feed unless increasing the gradient in the thin recording paper. Consequently, the gradient of the center separation plate 15 is set small corresponding to a sheet width of post card size for the thick paper, and the gradient of the both ends separation plate 16 is set large corresponding to the recording sheets similar to thin copying sheets of ordinary size.
