摘要： Two paper trays 11, 12 are disposed in such a manner that they are superimposed on top of each other in the vertical direction, a first paper feed roller 13 for feeding out paper from the upper-side paper tray 11 is disposed backwardly of and obliquely upwardly of a second paper feed roller 14 with respect to a direction in which the paper is fed out, and the upper-side paper tray 11 is disposed backwardly of and adjacently to the second paper feed roller 14. The sheets of paper fed out from the upper- and lower-side paper trays are delivered along the upper or lower surface of the second paper feed roller 14 and a are then fed into a common registration roller 10 without providing a delivery roller on the way. A holder 18 for supporting a handling member 16 to be contacted with the second paper feed roller 14 is supported by the paper tray 12 and can be retreated downwardly when pulling out the paper tray 12.

摘要： A registration roller 30 is preferably interposed between a first tangent line L1 passing through a handling portion between a first sheet feed roller 38 and a first handling member 42, and a second tangent line L2 passing through a handling portion between a second sheet feed roller 40 and a second handling member 44 (or the registration roller 30 may also be disposed so as to project out slightly from this range), and also the registration roller 30 may be preferably disposed downwardly of a horizontal line L3 passing through an upper end of the first sheet feed roller 38. In case where the first sheet feed roller 38, the second sheet feed roller 40 and the registration roller 30 are disposed so as to be as close as possible to one another, the height dimensions of a sheet feed apparatus 28 can be reduced to a minimum. Also, according to the above layout, since the registration roller 30 and the second sheet feed roller 40 are allowed to approach each other, a semilunar roller which has simple in structure can be used as the second sheet feed roller 40.
