Patent ID: 8414206

Claim:
A sheet conveying device comprising: a feed tray configured to store a plurality of sheets; a first conveying mechanism comprising a first conveying roller and configured to convey a first sheet that is a topmost sheet of the plurality of sheets in a first direction along a first conveying path such that a second sheet below the first sheet becomes the topmost sheet of the plurality of sheets; a second conveying mechanism comprising a second conveying roller and configured to convey the first sheet in a second direction along a second conveying path which is connected to the first conveying path and to the feed tray, wherein the second direction is substantially opposite to the first direction; a feeding mechanism comprising a feed roller and configured to move such that the feed roller contacts the first sheet at a contact position overlying the feed tray, feeds the first sheet from the feed tray to the first conveying path, and feeds the first sheet from the second conveying path again to the first conveying path; and a multiple feed guide disposed in the second conveying path and comprising: a guide portion configured to guide the first sheet conveyed along the second conveying path to the contact position; and an overlying portion disposed on at least one side of the feed roller in an axial direction and configured to contact the topmost sheet of the plurality of sheets at a more downstream position in the second direction than the contact position, and to move vertically corresponding to a number of the plurality of sheets in the feed tray without contacting the feeding mechanism.
