Abstract:
It is an object of the present invention to provide method for receiving sheets for a sheet supplying apparatus. The method includes converting an up and down motion of a tray to a rotational motion of a rotary member by a movement conversion mechanism, converting the rotational motion of the rotary member around a rotational axis to a linear motion of a cylindrical member parallel to the rotational axis by the rotary member and a cam and slider mechanism, and elastically pressing an end portion of the cylindrical member of the cam and slider mechanism in the rotational axis direction to lift the tray by a compression spring.

Claim (Index 1):
A method for receiving sheets for a sheet supplying apparatus having a tray on which plural sheets are stackable, a guide mechanism configured to freely guide the tray in an up and down direction, a movement conversion mechanism configured to convert an up and down motion of the tray to a rotational motion, a rotary member rotatably supported around a predetermined rotational axis and comprising a transmitted portion configured to receive a rotational motion converted from the up and down motion of the tray in cooperation with the movement conversion mechanism and a driven portion configured to receive a rotational driving force from a driving source to lift the tray, a cam and slider mechanism having a protrusion which integrally rotates with the rotary member and a cylindrical member through which the rotary member is inserted, the cylindrical member having a spiral groove formed on an inner surface thereof, and configured to convert the rotational motion of the rotary member around the rotational axis to a linear motion of the cylindrical member parallel to the rotational axis, and a compression spring configured to elastically press an end portion of the cylindrical member of the cam and slider mechanism in the rotational axis direction to lift the tray, the method comprising:\n converting an up and down motion of the tray to a rotational motion of the rotary member by the movement conversion mechanism; converting the rotational motion of the rotary member around the rotational axis to a linear motion of the cylindrical member parallel to the rotational axis by the rotary member and the cam and slider mechanism; and elastically pressing an end portion of the cylindrical member of the cam and slider mechanism in the rotational axis direction to lift the tray by the compression spring.
