Abstract

An image forming apparatus includes an apparatus main body that carries out an image forming processing with respect to a sheet. A sheet supplying unit is mounted detachably into the apparatus main body and adapted to supply a sheet from a stack of sheets stored therein toward an inside of the apparatus main body. The sheet supplying unit includes a position keeper for keeping the sheet stack in a determined position by contacting sides of the stack. The keeping position is changeable in accordance with the size of a sheet. A lock mechanism locks the position keeper in a keeping position. The locking mechanism releases the locking of the position keeper when the sheet supplying unit is detached from the apparatus main body and placed on a surface. However, the locking mechanism locks the position keeper when the sheet supplying unit is lifted from the surface.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an image forming apparatus provided with a sheet supplying unit detachably mounted into an apparatus main body and adapted to supply a sheet toward an inside of the apparatus main body.[0003]2. Description of the Related Art[0004]An image forming apparatus usually forms an image based on image information read by a scanner or transmitted from an external equipment such as a computer, and prints the image on the sheet. The image forming apparatus includes a sheet cassette (a sheet supplying unit) detachably mounted into an apparatus main body, and the sheet cassette contains a plurality of sheets (a stack of sheets) therein. A sheet is picked up from the sheet cassette to be brought to an image forming processing.[0005]The sheet cassette is formed with a pair of cursor members for positioning the sheet stack in a widthwise direction in accordance with a sheet size, and an end fence for po...
