A sheet conveying apparatus disposed below an image forming unit in a vertical direction and configured to convey a sheet to the image forming unit from below the image forming unit in the vertical direction, the sheet conveying apparatus comprising:
- an apparatus main body including a sheet storing unit configured to store a sheet;
- an opening/closing member configured to be openable and closable with respect to the apparatus main body;
- a conveying member configured to convey a sheet from the sheet storing unit to the image forming unit;
- a first conveyance guide provided in the apparatus main body, wherein the first conveyance guide is part of a conveyance path configured to guide, from a lower portion towards an upper portion of the apparatus main body;
- a second conveyance guide provided on the opening/closing member and configured to form the conveyance path together with the first conveyance guide wherein the second conveyance guide opposes the first conveyance guide and forms the conveyance path in a case in which the opening/closing member is in a closed state with respect to the apparatus main body, and the second conveyance guide is separated from the first conveyance guide and the conveyance path is open in a case in which the opening/closing member is in an open state with respect to the apparatus main body;
- a first support portion provided above the center of the opening/closing member in the vertical direction, wherein the first support portion includes a first projecting portion provided on either of the apparatus main body and the opening/closing member and a first hole portion in the other of the apparatus main body and the opening/closing member and that engages with the first projecting portion, and wherein the first supporting portion rotatably supports the opening/closing member with respect to the apparatus main body by the first projecting portion and the first hole portion relatively moving in a circumferential direction of the first hole portion;
- a second support portion provided below the first support portion in the vertical direction, wherein the second support portion includes a second projecting portion provided on either one of the apparatus main body and the opening/closing member and a second hole portion provided in the other of the apparatus main body and the opening/closing member and that engages with the second projecting portion, and wherein the second supporting portion rotatably supports the opening/closing member with respect to the apparatus main body by the second projecting portion and the second hole portion relatively moving in a circumferential direction of the second hole portion and
- a third support portion provided below the second support portion in the vertical direction, wherein the third support portion includes a third projecting portion provided on either one of the apparatus main body and the opening/closing member and a third hole portion provided in the other of the apparatus main body and the opening/closing member and that engages with the third projecting portion, and wherein the third supporting portion rotatably supports the opening/closing member with respect to the apparatus main body by the third projecting portion and the third hole portion relatively moving in a circumferential direction of the third hole portion
- wherein a difference between a greatest length of the third projecting portion in a predetermined direction, orthogonal to both the vertical direction and a width direction of the sheet conveyed between the first conveyance guide and the second conveyance guide and a greatest length of the third hole portion in the predetermined direction, in a case where the opening/closing member is in the closed state, is larger than a difference between a greatest length of the first projecting portion in the predetermined direction and a greatest length of the first hole portion in the predetermined direction, in a case where the opening/closing member is in the closed state, and
- wherein a difference between a greatest length of the third projecting portion in the predetermined direction and on a straight line passing through a rotation center of the third support portion and a greatest length of the third hole portion in the predetermined direction in a case where the opening/closing member is in the closed state, is larger than a difference between a greatest length of the second projecting portion in the predetermined direction and on the straight line passing through a rotation center of the second support portion, in a case where the opening/closing member is in the closed state.
