摘要

A sheet feeder for feeding mails includes a mounting table (11) having a slanted top surface for mounting thereon a plurality of sheets (30a) in a substantially upright posture thereof, a transfer belt (11) for transferring the sheets in the slanted posture in the direction (A) perpendicular to the surfaces of the sheets (30), and a take-out section (16) for taking out the sheets (30a) in the horizontal direction parallel to the surfaces of the sheets (30). A mail (30a) having an envelope (31) and a belt wrapper (32) covering the envelope (31) can be taken out as it is, without pulling-off of the belt wrapper (32) from the envelope (31). <IMAGE>
