Claims

[Scope of utility model registration request]

A first state in which a mounting plate lifting tool that lifts and biases the recording paper mounting plate in the cassette case toward the paper feeding means side is lifted toward the paper feeding means side, and a second state in which insertion and removal of the cassette case is permitted. A cam follower for swinging the loading plate lifting tool is provided on the main body side of the device so as to be able to swing freely between the two, and a cam follower for swinging the mounting plate lifting tool is connected to the lifting tool. a first switch for switching the mounting plate lifting tool between the first state and the second state by relative contact;
and in a paper feeding device of an image recording apparatus in which a second cam is provided in the cassette case, the end of the relative movement of the cam follower in the first cam when the cassette case is inserted is equal to the relative movement of the cam follower in the second cam when the cassette case is removed. The first and second cams are formed at different positions in the direction of the swing axis of the mounting plate lifting tool so as to be located upstream of the terminal end in the cassette case insertion direction, and the cam follower is formed at different positions in the direction of the swing axis of the mounting plate lifting tool. a third cam configured to be freely changeable in position over the first and second cams, and to move the cam follower to the second cam side when the cam follower passes the end of relative movement in the first cam; A paper feeding device for an image recording apparatus, characterized in that a biasing means for shifting the cam follower from the second cam side to the first cam side is provided.
