Abstract

PURPOSE: To make sheet feeding accurately performable even if the insertion of each sheet by manual operation or the like is not sufficient enough by installing a freely retractable projection in a sheet feeding member.
CONSTITUTION: When a start key is pushed after a sheet S1 is inserted thereinto by manual operation or the like, a paper feeding member 1 gets rotating clockwise, and each of projections 10d, 10e comes into contact with this sheet S1. If this paper feeding member 1 is rotating in a arrow C direction, the sheet S1 is fed in an arrow D direction by dint of frictional force out of these projections 10d, 10e. When the paper feeding member 1 is further rotated, since an interval between these projections 10d, 10e and a topmost sheet S0 is narrowed, these projections 10d, 10e receive pressure from sheets S in a housing 3 via the sheet S1. However, since these projections 10d, 10e and an outer layer part 10 have elasticity each, these projections 10d, 10e are sunk in cavities 12, 13 installed at both sides of the paper feeding member 1, so that the sheet S1 receives frictional force of a friction member 10c from its whole surface and conveyed in the arrow D direction.
