Abstract
A sheet feeding device includes a casing; a door rotatable relative to the casing; a tray configured to stack a sheet thereon and rotatable between a closed position where the tray is closed to the casing, a first open position where the tray opens relative to the casing at a first angle, and a second open position where the tray opens relative to the casing at a second angle larger than the first angle; and a sheet feeding unit provided in the casing and configured to feed the sheet stacked on the tray being in the first position. When the door is opened relative to the casing at an angle exceeding the first angle in a state in which the tray is in the first open position, the door moves the tray to the second open position.
Claims13
A sheet feeding device comprising:
- a casing;
- a door rotatable relative to said casing;
- a tray configured to stack a sheet thereon and rotatable between (a) a first closed position where said tray is closed to said casing, (b) a first open position where said tray opens relative to said casing at a first angle, and (c) a second open position where said tray opens relative to said casing at a second angle larger than the first angle;
- and
- a sheet feeder provided in said casing and configured to feed the sheet stacked on said tray being in the first open position,
- wherein said door is rotatable between (a) a second closed position where said door is closed to said casing, (b) a third open position where said door opens relative to said casing at an angle not exceeding the angle of said tray in the first open position, and (c) a fourth open position where said door opens relative to said casing at an angle exceeding the angle of said tray in the first open position,
- wherein when said door is opened from the second closed position to the third open position in a state in which said tray is in the first open position, said tray keeps in the first open position, and
- wherein when said door moves from the third open position to the fourth open position, said door moves said tray from the first open position to the second open position.

An image forming apparatus comprising:
- a casing;
- a door rotatable relative to said casing;
- a tray configured to stack a sheet thereon and rotatable between (a) a first closed position where said tray is closed to said casing, (b) a first open position where said tray opens relative to said casing at a first angle, and (c) a second open position where said tray opens relative to said casing at a second angle larger than the first angle;
- a sheet feeder provided in said casing and configured to feed the sheet stacked on said tray being in the first open position;
- and
- an image forming portion provided in said casing and configured to form an image on the sheet fed by said sheet feeding device,
- wherein said door is rotatable between (a) a second closed position where said door is closed to said casing, (b) a third open position where said door opens relative to said casing at an angle not exceeding the angle of said tray in the first open position, and (c) a fourth open position where said door opens relative to said casing at an angle exceeding the angle of said tray in the first open position,
- wherein when said door is opened from the second closed position to the third open position in a state in which said tray is in the first open position, said tray keeps in the first open position, and
- wherein when said door moves from the third open position to the fourth open position, said door moves said tray from the first open position to the second open position.

A sheet feeding device comprising:
- a casing;
- a door rotatably provided to said casing;
- a tray configured to stack a sheet thereon and rotatable between (a) a closed position where said tray is closed to said casing, (b) a first open position where said tray opens relative to said casing at a first angle, and (c) a second open position where said tray opens relative to said casing at a second angle larger than the first angle;
- and
- a sheet feeder configured to feed the sheet stacked on said tray;
- a regulating portion including an engaging portion slidably engaging with said tray and configured to be rotatably supported by said casing;
- an urging member configured to urge said engaging portion upward relative to said tray when said tray is in the first open position,
- wherein said tray includes (a) a first guiding passage for guiding said engaging portion between the closed position and the first open position and (b) a second guiding passage for guiding said engaging portion when said engaging portion moves toward the second open position,
- wherein said door includes a contact portion contactable to said regulating portion from above said tray when said tray is in the first open position, and
- wherein said engaging portion is guided from the first guiding passage to the second guiding passage by contact of said contact portion to said regulating portion.
