Abstract

There is provided a cabling apparatus comprising, a cable connecting a first unit and a second unit which turns around a turning axial line of a hinge portion with respect to the first unit via the hinge portion, a cable guide portion, which guides the cable, in which the cable guide portion is turnably attached to the second unit on one end side of the cable guide portion and is connected to the first unit on the other end side of the cable guide portion, wherein a turning axial line of the guide portion with respect to the second unit and a turning axial line of the hinge portion accord with each other.

Claims

1. An image reading apparatus comprising:

an apparatus body having an image reading unit which reads an original image;

an original conveying apparatus which turns around a turning axial line of a hinge portion with respect to the apparatus body via the hinge portion and conveys an original onto an original image read position in the apparatus body;

a cable connecting the apparatus body and the original conveying apparatus to each other; and

a cable guide portion, which guides the cable, in which the cable guide portion is turnably attached to the original conveying apparatus on one end side of the cable guide portion and is connected to the apparatus body on the other end side of the cable guide portion,

wherein a turning axial line of the guide portion with respect to the original conveying apparatus and a turning axial line of the hinge portion accord with each other.

2. An image reading apparatus according to claim 1,

the guide portion has a first guide member that is turnably attached to the apparatus body on one end of the first guide member, and a second guide member that is turnably attached to the original conveying apparatus on one end of the second guide member

wherein the first guide member and the second guide member are pivotably connected to each other on the other end sides of the first guide member and the second guide member.

3. An image reading apparatus according to claim 2, further comprising:

a moving mechanism configured to move the original conveying apparatus away from the apparatus body,

wherein the original conveying apparatus is brought into a first state in which the original conveying apparatus is closed with respect to the apparatus body, brought into a second state in which the original conveying apparatus is opened with respect to the apparatus body by turning around the turning axial line of the hinge portion, and brought into a third state in which the original conveying apparatus is apart from the apparatus body by moving through the moving mechanism.

4. An image reading apparatus according to claim 3,

wherein when the conveying unit changes from the second state to the third state, the first guide member is turned with respect to the second guide member.

5. An image forming apparatus comprising:

an first unit;

a second unit which turns around a turning axial line of a hinge portion with respect to the first unit via the hinge portion;

a cable connecting the first unit and the second unit to each other; and

a cable guide portion, which guides the cable, in which the cable guide portion is turnably attached to the second unit on one end side of the cable guide portion and is connected to the first unit on the other end side of the cable guide portion,

wherein a turning axial line of the guide portion with respect to the first unit and a turning axial line of the hinge portion accord with each other.

6. An image forming apparatus according to claim 5,

the guide portion has a first guide member that is turnably attached to the first unit on one end of the first guide member, and a second guide member that is turnably attached to the second unit on one end of the second guide member

wherein the first guide member and the second guide member are pivotably connected to each other on the other end sides of the first guide member and the second guide member.

7. An image forming apparatus according to claim 6, further comprising:

a moving mechanism configured to move the second unit away from the first unit,

wherein the second unit is brought into a first state in which the second unit is closed with respect to the first unit, brought into a second state in which the second unit is opened with respect to the first unit by turning around the turning axial line of the hinge portion, and brought into a third state in which the second unit is apart from the first unit by moving through the moving mechanism.

8. An image forming apparatus according to claim 7,

wherein when the second unit change from the second state to the third state, the first guide member is turned with respect to the second guide member.

9. A cabling apparatus comprising:

a cable connecting a first unit and a second unit which turns around a turning axial line of a hinge portion with respect to the first unit via the hinge portion;

a cable guide portion, which guides the cable, in which the cable guide portion is turnably attached to the second unit on one end side of the cable guide portion and is connected to the first unit on the other end side of the cable guide portion,

wherein a turning axial line of the guide portion with respect to the second unit and a turning axial line of the hinge portion accord with each other.

10. A cabling apparatus according to claim 9,

the guide portion has a first guide member that is turnably attached to the first unit on one end of the first guide member, and a second guide member that is turnably attached to the second unit on one end of the second guide member

wherein the first guide member and the second guide member are pivotably connected to each other on the other end sides of the first guide member and the second guide member.

11. The cabling apparatus according to claim 10, wherein the second unit can move away from the second unit by a moving mechanism,

wherein the original conveying apparatus is brought into a first state in which the original conveying apparatus is closed with respect to the apparatus body, brought into a second state in which the original conveying apparatus is opened with respect to the apparatus body by turning around the turning axial line of the hinge portion, and brought into a third state in which the original conveying apparatus is apart from the apparatus body by moving through the moving mechanism, and

wherein when the second unit changes from the second state to the third state, the first guide member is turned with respect to the second guide member.
