Abstract: A sheet conveying device includes a blocking member having a blocking surface with which a leading end of a sheet that is being conveyed comes into contact for obliquity correction. The blocking member is rotated by being pushed by the sheet against an urging force of a positioning unit that positions the blocking member to be in the standby position. The blocking member is rotatable to be in a sheet-passage-allowing orientation in which the sheet is allowed to pass. When a trailing end of the sheet that is being conveyed has passed the blocking member, the blocking member that is in the sheet-passage-allowing orientation rotates in a same direction as a sheet conveyance direction and is positioned to be in a standby position.

Abstract: The present invention is a part positioning mechanism configured to insert a protruding portion constituting a part of a second sheet metal part into an opening formed in a first sheet metal part. The first contact portion which contacts the first convex portion of the first sheet metal and the second contact portion which contacts the second convex portion of the first sheet metal are disposed to be shifted in an orthogonal direction which intersects orthogonally with the plate thickness direction and an insertion direction for the protruding portion. The edge of the opening of the first sheet metal part has a first edge which is distant from the protruding portion increases from the first convex portion to the second convex portion, and a second edge which is distant from the protruding portion increases from the second convex portion to the first convex portion.
