<p>PURPOSE:To miniaturize a device and improve sureness of a sheet feed, in the feeder device used for facsimile or the like, by arranging, to the upstream of a separator roller, a suctin box loaded with negative pressure and made movable vertically and in the feed direction. CONSTITUTION:Simultaneously with start of feeding, a separator roller 3 is driven to both apply negative pressure to the interior of a negative pressure box 11 and rotate by 1/2 vertically movable cams 23, 24. In this way, each friction plate 19 on the suction box 11 is protruded from the level of a mounting bed 1 through horizontal elements 15, 16 and a long hole 10 of the mounting bed 1. Thus the lowermost sheet of a sheet pile 6 can be sucked by the friction plate 19. Then a longitudinally movable cam 25 is 1/2 rotatd, and the suction box 11 and the friction plate 19 are moved forward through a vertical element 17, then the sheet, sucked by the friction plate 19, is fed between the separator roller 3 and a brake plate 4. In this constitution, the height of a device can be reduced to miniaturize the device, and capability of a sheet feed can be increased to surely perform the sheet feed.</p> |
