10. A recording device, comprising:
a reading device including a reader configured to read an image of a document;
a placement member at which a medium is placed;
a recorder configured to perform recording on the medium transported from the placement member; and
an edge guide configured to guide the medium by coming into contact with an edge of the medium placed at the placement member, wherein
a size of the medium is determined by emitting light from the reader toward a detection target and calculating a position thereof, the position of the detection target changing in accordance with the size of the medium placed at the placement member,
the placement member is disposed in an inclined posture at a rear surface of a device main body,
the reader reads the image by moving in a first moving direction with respect to the document,
a position of the edge guide, as the detection target, is determined by the reader emitting the light while moving in the first moving direction,
the detection target is a member extending from the edge guide, and
the member is rotatably provided at the edge guide.
