<p>PROBLEM TO BE SOLVED: To provide a transport mechanism which enables a transport roller to be easily attached and detached and improves the attachment stability of the transport roller, and to provide an image formation device including the transport mechanism.SOLUTION: A paper feeding mechanism 500 includes: a paper feeding roller assembly 330 including a paper feeding roller 335 that transports a sheet and a roller support section 310 which may expand and retract in an axial direction; a bearing 341 which rotatably and detachably supports a first end part 333 of the roller support section 310; a connection section 342 to which a second end part 334 of the roller support section 310 is detachably connected; a pin 345 which supports the bearing 341 so that the bearing 341 swings between a first position where the bearing 341 faces the connection section 342 and a second position where the bearing 341 does not face the connection section 342; and a plate spring 344 which biases the bearing 341 from the first position to the second position. The plate spring 344 is formed by a plate-like elastic body which extends from the bearing 341 at a predetermined opening angle.</p> |
