Patent ID: 8428507

Claim:
A sheet feeding device, comprising: a sheet conveying path in which a sheet is conveyed in a predetermined direction; a first conveying roller pair having a first conveying roller disposed in the sheet conveying path and conveying the sheet in the predetermined direction; a second conveying roller pair having a second conveying roller disposed downstream of the first conveying roller in the sheet conveying path and conveying the sheet, conveyed from the first conveying roller, in the predetermined direction; a first driving gear attached coaxially to the first conveying roller for rotation therewith and having a first number of teeth; a second driving gear attached coaxially to the second conveying roller for rotation therewith and having a second number of teeth; and a drive source driving the first driving gear and the second driving gear, wherein, when an end of the sheet on an upstream side in the predetermined direction is sandwiched by the first conveying roller pair and an end of the sheet on a downstream side in the predetermined direction is sandwiched by the second conveying roller pair, the expression A>B is satisfied, where A is a first meshing frequency defined by multiplication of the first number of teeth and the number of rotations of the first driving gear and B is a second meshing frequency defined by multiplication of the second number of teeth and the number of rotations of the second driving gear.
