Abstract
A print medium supplying device, includes a frame, a mounting plate to mount a print medium, an elevating unit to move upward and downward the mounting plate within the frame, and an elastic unit which comprises an installation unit disposed to one of the frame and the mounting plate, a coupling unit coupled to an other of the frame and the mounting plate, and a spring unit provided between the installation unit and the coupling unit to elastically weaken a falling motion of the mounting plate.
Claims15
An image forming apparatus, comprising:
- a print medium supplying device comprising:
- a frame;
- a mounting plate to mount a print medium;
- an elevating unit to move upward and downward the mounting plate within the frame;
- and
- an elastic unit comprising an installation unit disposed to one of the frame and the mounting plate, a coupling unit to selectively couple to an other of the frame and the mounting plate, and a spring unit provided between the installation unit and the coupling unit to elastically weaken a falling motion of the mounting plate;
- and
- an image forming unit to form an image with respect to the print medium supplied by the print medium supplying device.
An image forming apparatus, comprising:
- a print medium supplying device, comprising:
- a frame;
- a mounting plate disposed in the frame to move upward and downward, and to mount a print medium;
- an elevating unit which is disposed in the frame to adjust a height of the mounting plate based on a number of the print media mounted on the mounting plate;
- and
- an elastic unit to elastically support the mounting plate to reduce a falling impact when the mounting plate which is lifted to a predetermined height falls down according to a release of a driving force to drive the elevating unit, wherein the elastic unit comprises an installation unit disposed in the frame, a coupling unit to selectively couple the mounting plate, and a spring unit provided between the installation unit and the coupling unit to elastically weaken a falling motion of the mounting plate;
- and
- an image forming unit to form an image with respect to the print medium supplied by the print medium supplying device.
A print medium supplying device usable with an image forming apparatus, the print medium supplying device comprising:
- a frame;
- a mounting plate disposed proximate to the frame to store and to supply a print medium;
- and one or more elastic units disposed between the frame and the mounting plate to elastically weaken a falling motion of the mounting plate, wherein the one or more elastic units comprise an installation unit disposed to one of the frame and the mounting plate, a coupling unit to selectively couple at least one of the frame and the mounting plate, when the mounting plate falls below a predetermined height, and a spring unit disposed between the installation unit and the coupling unit to elastically weaken the falling motion of the mounting plate.
A print medium supplying device usable with an image forming apparatus, the print medium supply device comprising:
- a frame;
- a mounting plate disposed in the frame to move with respect to the frame to support a print medium;
- and
- an elastic unit disposed at a position within a moving distance of the mounting plate and comprising an installation unit disposed in the frame, a coupling unit to selectively couple to the mounting plate to apply a variable elastic force to the mounting plate, and a spring unit provided between the installation unit and the coupling unit to elastically weaken a falling motion of the mounting plate.
