Abstract

A sheet supply cassette includes a main frame body and an auxiliary frame body slidable with respect to the main frame body. In the main frame body, there is disposed a sheet placement plate which moves up and down according to the residual quantity of sheets placed, and there is disposed a sheet residual quantity display mechanism which displays the sheet residual quantity according to the upward and downward movements of the sheet placement plate. The display mechanism includes a sheet residual quantity detect portion for detecting the residual quantity of sheets, a sheet residual quantity display portion disposed on the front surface cover portion of the auxiliary frame body, and a connecting portion for connecting together the sheet residual quantity detect portion and sheet residual quantity display portion, while the connecting portion can be expanded and contracted according to the expansion and contraction of the sheet supply cassette.

Description

technical field [0001] The present invention relates to a paper feeding cassette for storing sheets therein and an electrophotographic type image forming apparatus including the paper feeding cassette. Background technique [0002] As for the paper feeding cassette used in the image forming apparatus, it is known that the paper feeding cassette includes a main frame body and an auxiliary frame body slidably arranged on the main frame body, while the auxiliary frame body can be adjusted according to the size of the stored paper. Expanding and retracting are performed (see JP-A-5-51136). There is also known a paper remaining amount mechanism which detects the remaining number of sheets in the paper feeder to display the remaining number of sheets in the paper feeder (see JP-A-6-271141 and JP-A-10-194479). [0003] However, there is generally no known method of applying a remaining sheet number display mechanism to an expandable and retractable paper feeding cassette. Since t...
