Printing apparatus

A printing apparatus comprising:

• an apparatus main body;
• a printing unit that performs printing on a medium;
• a medium accommodating member that is detachably provided in the apparatus main body and is capable of accommodating the medium;
• a first roller that is provided in the apparatus main body, and picks up the medium from the medium accommodating member by being brought in contact with the medium which is accommodated in the medium accommodating member mounted in the apparatus main body and being driven to rotate;
• a second roller that is provided in the apparatus main body, is disposed on a downstream side of the first roller in a transporting direction of the medium, and is brought into contact with the medium picked up by the first roller on the same surface as a surface with which the first roller comes into contact and is driven to rotate;
• a third roller that is provided in the apparatus main body, and is brought into contact with the medium picked up by the first roller on a surface opposite to the surface with which the first roller comes into contact and is rotated following the second roller;
• a driving source of the first roller and the second roller;
• and
• a displacing mechanism that displaces a position of the third roller with respect to the second roller depending on attaching and detaching of the medium accommodating member to and from the apparatus main body,
• wherein the medium accommodating member includes a hopper which is movable between a feeding position in which the medium to be accommodated is pressed to the first roller by a pressing force of a pressing member and a standby position in which the medium is separated from the first roller against the pressing force of the pressing member,
• wherein the displacing mechanism displaces the third roller to a contacting position in which the third roller is capable of coming into contact with the second roller when the medium accommodating member is mounted in the apparatus main body, and displaces the third roller to a non contacting position in which the third roller is separated from the second roller when the medium accommodating member is pulled out from the apparatus main body, and
• wherein the first roller is rotatable in a reverse rotating direction opposite to a rotating direction of the driven rotation due to the frictional force with the pulled out medium in accordance with the pulling-out of the medium accommodating member under a circumstance in which the medium is pressed by the hopper present at the feeding position.
