1. A pull-out lock device, provided in an image-forming apparatus main body, that allows a sheet container to be pulled out in a predetermined pull-out direction, the sheet container capable of loading a plurality of sheets and including a plurality of sheet containers placed side by side in a vertical direction in the image-forming apparatus main body, the pull-out lock device for the sheet container comprising a lock member including:
a main body that is attached so as to be rotatable around a rotation axis relative to the image-forming apparatus main body;
a rotation member that supports the main body so as to be rotatable around the rotation axis;
a contact member; and
a lock, wherein
while two adjacent sheet containers, among the plurality of sheet containers, are both located at an accommodated position in the image-forming apparatus main body, the contact member is in contact with one of the two adjacent sheet containers, such that the lock member rotates around the rotation axis, and the lock moves to an unlock position to allow another one of the two adjacent sheet containers to move in the predetermined pull-out direction, and
when the other one of the two adjacent sheet containers is located at the accommodated position and the one of the two adjacent sheet containers is pulled out in the predetermined pull-out direction from the accommodated position and a contact between the one of the two adjacent sheet containers and the contact member is removed, the lock member rotates around the rotation axis, and the lock moves to a lock position to prohibit the other one of the two adjacent sheet containers from moving in the predetermined pull-out direction.
