Abstract
A cover opening and closing unit includes a cover installed to be opened from and close a main body and a manual paper feed tray that is rotatably installed on the cover. The cover is connected to the main body by a link element and a connection link is connected to the link element and the manual paper feed tray so that, when the cover is opened from the main body when the manual paper feed tray is in an opened state with respect to the cover, an open angle of the manual paper feed tray with respect to a vertical direction is maintained within 90 degrees.
Claims16
A cover opening and closing unit comprising:
- a cover installed to be opened and closed from a main body;
- a manual paper feed tray on which sheets of paper are loaded, the manual paper feed tray being installed on the cover to rotate to a closed position and an opened position, said opened position having an open angle with respect to a vertical direction;
- a link element connecting the cover to the main body;
- and
- a connection link having a first end rotatably connected to the link element and a second end slidably connected to a guide rail installed on a side of the manual paper feed tray, the connection link interacting with a rotation of the link element so that, when the cover is opened when the manual paper feed tray is positioned in the opened position, the open angle of the manual paper feed tray is maintained so as to be equal to or less than 90 degrees with respect to a vertical direction.
A cover opening and closing unit comprising:
- a cover installed to be opened and closed from a main body;
- a manual paper feed tray on which sheets of paper are loaded, installed on the cover to rotate to a closed position and an opened position, and comprising a guide rail;
- a link element connecting the cover to the main body and comprising a plurality of links that rotate with respect to each other in a direction in which the plurality of links are unfolded from each other or folded with each other when the cover is opened or closed;
- and
- a connection link having a first end that is rotatably connected to one of the plurality of links and a second end that is slidably connected to the guide rail, the connection link interacting with the rotation of the plurality of links so that, when the cover is opened when the manual paper feed tray is positioned in the opened position, an open angle of the manual paper feed tray with respect to a vertical direction is maintained so as to be equal to or less than 90 degrees.
