1. A medium transport apparatus comprising:
a first roller that transports a medium;
a second roller that nips the medium together with the first roller;
a first rotating shaft that rotatably supports the first roller;
a second rotating shaft that rotatably supports the second roller;
a support mechanism that supports the first rotating shaft and the second rotating shaft;
a main body that supports the support mechanism;
a door that opens and closes with respect to the main body and the support mechanism; and
a third rotating shaft that allows the door to be rotated between a closed location and an open location, the third rotating shaft extending along a direction intersecting the first rotating shaft, the closed location being a location of the door closed, the open location being a location of the door open,
wherein when the door is rotated from the closed location to the open location, the support mechanism moves the first rotating shaft from a nip point at which the first roller and the second roller nip the medium and an escaped position at which the first roller escapes from the second roller, the escaped point being further from the first roller positioned at the nip point than the nip point, and
wherein the support mechanism comprises:
a first contact section configured to make contact with the door at a first end and being configured to move in an axial direction along the first rotating shaft,
a first moving section that moves a first end of the first rotating shaft by receiving a force generated by contact between the first contact section and the door and applying a biasing force to the first end of the first rotating shaft.
