Medium conveying apparatus including light guide which is bent

A medium conveying apparatus comprising:

• a set guide to set a medium;
• a feed roller to feed the medium set on the set guide;
• a conveying roller to convey the medium fed by the feed roller to a downstream side;
• a moving mechanism located on the downstream side of the set guide in a medium conveying direction, to move the set guide;
• a guide pair including a first guide having a first opening and a second opening provided between the feed roller and the conveying roller in the medium conveying direction to detect the medium fed by the feed roller, and a second guide located so as to sandwich a medium conveyance path together with the first guide, to regulate a vertical direction of the medium conveyance path;
• a light emitting element and a light receiving element located on an outside of the medium conveyance path with the first guide in between, and on the downstream side of the first opening and the second opening so as to be apart from the moving mechanism by a predetermined distance or more in the medium conveying direction;
• a first light guide which is bent so as to guide a light emitted from the light emitting element to the first opening;
• and
• a second light guide which is bent so as to guide the light incident from the second opening to the light receiving element.
