Claims

[Claims for Utility Model Registration] (1) An image of a paper feed cassette that can store multiple types of paper of different sizes and is equipped with a regulating member that regulates the paper side edge according to the paper size to be stored. A paper feeding device configured to be detachably attached to the image forming apparatus main body includes: a paper size detection circuit provided in the image forming apparatus main body; and a paper size detection circuit provided in the paper feeding cassette to connect the paper feeding cassette to the image forming apparatus main body. a connecting terminal section having a plurality of terminals connected to the paper size detection circuit when attached to the paper size detection circuit; a plurality of signal paths arranged to connect between predetermined terminals of the connecting terminal section; and the signal path. contact portions each provided in the vicinity of a position where the regulating member is fixed according to the paper size, and where the predetermined terminals are connected or disconnected when the regulating member is fixed; A paper feeding device comprising: (2) The paper feeding device according to claim 1, wherein the regulating member is a paper width direction regulating plate or a longitudinal direction regulating plate. (3) The paper feeding device according to claim 1, wherein the signal path is formed of a flexible substrate. (4) The paper feeding device according to claim 1, wherein the signal path is constructed by disposing a conductive pattern directly on the paper feeding cassette. (5) The paper feeding device according to claim 1, wherein the signal path is disposed on the bottom back surface of the paper feeding cassette.
