Abstract:
1. A scanner comprising: a main body including a first transparent plate on the top surface; a hinge connected to the main body; a cover member connected to the hinge, wherein the cover member has a bottom surface, the cover member rotates using the hinge with respect to the main body between an opened state and a closed state, and the bottom surface is in contact with the top surface of the main body in the closed state; and first and second sets, each set comprising a protrusion and a recess, wherein the protrusion is formed on one of the top surface of the main body and the bottom surface of the cover member, and the recess is formed on the other of the top surface of the main body and the bottom surface of the cover member, wherein in each of the first and second sets, the protrusion is inserted into the recess when the cover member rotates using the hinge from the opened state to the closed state, and the protrusion is pulled out from the recess in accordance with a rotation of the cover member when the cover member rotates using the hinge from the closed state to the opened state, in a plan view of the first transparent plate, each of the first and second sets is positioned at a different position from where the hinge is arranged, the first set being positioned closer to the hinge than the second set in a direction perpendicular to a rotation axis of the hinge, the first set comprises a first protrusion and a first recess which determine a position of the cover member with respect to the main body in a first direction, and the second set comprises a second protrusion and a second recess which determine a position of the cover member with respect to the main body in a second direction that is different from the first direction, the second recess having a different shape from the first recess, and the second recess having an elongated shape that is elongated in the direction perpendicular to the rotation axis of the hinge.
