Abstract

A sheet feeding mechanism includes a sheet feed roller for transporting a sheet along a paper transport path, and a sheet- pressing member disposed so as to press the sheet feed roller. The sheet-pressing member integrally includes a pressing portion which is formed by increasing the diameter of a part of a coiled portion of a compression coil spring.
