１項記載のシート供給装置。[Claims for Utility Model Registration] 1. A sheet loading table on which a plurality of sheet bundles are placed;
a sheet feeding means that contacts the lowest sheet of the sheet bundle; a sheet abutting member that causes the sheet bundle fed out by the feeding means to move back from the bottom sheet; and a sheet contacting member that sequentially feeds the fed sheets one by one. It is equipped with a feeding means, a driving means for driving the above-mentioned feeding means, and a control means for controlling the driving of the driving means, and this control means is configured to operate at a low speed for a predetermined period of time after the feeding is started in response to a feeding instruction signal. 1. A sheet feeding device characterized in that a driving means is actuated by a drive means and then controlled to operate at a high speed. 2. The control means operates the drive means at a low speed for a period of time during which only the lowest sheet is fed out after the feed-out is started in response to a sheet feed instruction signal, and then controls the drive means to operate at a high speed. The sheet feeding device according to item 1.
