1. A medium feeding device comprising:
a placement unit at which a medium is placed;
a transport path along which the medium is transported;
a feeding roller configured to feed the medium placed at the placement unit; and
a skew correction mechanism configured to correct skew of the medium being fed,
wherein the skew correction mechanism includes:
a first lever member and a second lever member configured to be displaced between an advanced position at which the first lever member and the second lever member come into contact with the medium and are advanced into the transport path and a retracted position at which the first lever member and the second lever member are retracted from the transport path by the medium passing therethrough in contact therewith; and
a first load member and a second load member that are provided downstream of the first lever member and the second lever member in a feeding direction of the medium and are configured to be displaced between a blocking position at which a part of the transport path in a width direction that intersects the feeding direction is blocked and an opening position at which the transport path is opened without being blocked,
the feeding roller is provided between the first load member and the second load member in the width direction,
the first load member and the second load member, when located at the blocking position, overlap at least a part of the feeding roller when seen in the width direction,
the first load member is configured to be located at the blocking position when the first lever member is located at the advanced position and to be displaced from the blocking position to the opening position when the first lever member is located at the retracted position, and
the second load member is configured to be located at the blocking position when the second lever member is located at the advanced position and to be displaced from the blocking position to the opening position when the second lever member is located at the retracted position.
