摘要： A medium transport device includes: a feeding roller that feeds a medium mounted on a medium mounting section; a separation roller that nips the medium with the feeding roller to separate the medium and is configured to rotate in a first rotation direction in which the medium is transported downstream and a second rotation direction that is opposite to the first rotation direction; a pressing member that presses the separation roller against the feeding roller; a pressing force change portion that changes a pressing force of the pressing member; and a single drive source that generates a driving force for the separation roller and a driving force for the pressing force change portion.

摘要： There is provided a medium transport device including a placement section on which a medium is placed, a transport path through which the medium is transported, a feeding roller that feeds the medium, a set guide configured to switch between a contact position where the medium and the feeding roller are brought into contact and a separation position where the medium and the feeding roller are separated, a restricting section configured to switch between a restricting position for restricting feeding of the medium by coming into contact with a leading end of the medium and an allowing position for allowing the feeding of the medium, and a drive source that generates power for switching of the set guide and switching of the restricting section. The set guide and the restricting section are provided below the transport path in a direction of gravity.

摘要： A medium placement device configured to have a medium discharged from a discharge unit of a processing device placed therein, and includes: a placement unit including a plurality of placement surfaces, with different angles with respect to a horizontal direction, that are disposed along a discharge direction of the medium, the placement unit being configured to have the medium discharged from the discharge unit placed thereon; and a plurality of restricting members disposed facing the placement unit along the discharge direction, the plurality of restricting members being configured to come into contact with the medium from above. In an initial state in which the medium is not placed, a distance in a gravitational direction between a first end of each of the plurality of restricting members on a placement unit side and one of the plurality of placement surfaces that faces the first end in the gravitational direction is constant.

摘要： A printer includes a recording unit, a support portion, a negative pressure chamber, a first sectioned chamber, a second sectioned chamber, a first suction port, and a second suction port. The support portion includes a support face configured to support roller paper. The negative pressure chamber is disposed at an opposite side of the support portion from the recording unit side. The first and the second sectioned chamber include a first and a second bottom surface. The first and the second suction port cause an outside space and the negative pressure chamber to communicate with each other. An opening area of the second suction port is smaller than an opening area of a first suction portion. The second suction port disposed most upstream in the first sectioned chamber is disposed upstream, in the transport direction, of the first suction port disposed most upstream in the second sectioned chamber.

摘要： A medium feeding device includes an imaging unit which images a medium tip end portion from a position of facing a face of the medium on a downstream side of a nipping position of the medium using a feeding unit and a separating unit; and a determining unit which determines whether or not there is transport disorder by evaluating a state of a boundary between a path member which forms a medium transport path and a medium tip end from image data obtained by the imaging unit, in which the determining unit sets a rectangular determining region including at least a part of the boundary with respect to the image data, and determines whether or not there is transport disorder based on a length of a boundary in the determining region.
