Sheet refeeding device for use in printing apparatus having a timed pressing member |
摘要 |
A recording sheet feeding device for use in an image forming machine, in which a plurality of sheets on which a first image has been recorded are successively fed from a sheet stacker for a second image to be formed, provided with a sheet pressing mechanism above the stacker which takes a pressing or a non-pressing position with respect to sheets on the stacker. While sheets are being conveyed to the stacker, a pressing operation on the sheets is conducted by driving the mechanism at least twice. Sheet feeding from the stacker is started after the first pressing operation of the mechanism. A feeding timing of the first sheet to be fed after a second pressing operation is delayed compared with a feeding timing of other sheets. In another structure, a periodical pressing operation is conducted each time a predetermined number of sheets are conveyed into the stacker and feeding is started when a sheet preceding by a fixed number from the last sheet in a set number of sheets in the first image forming operation is conveyed into the stacker.
