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