Abstract: A holder supports a separation member. When a sheet cassette is attached to a main body portion, as the sheet cassette is moved in its attachment direction, a moving mechanism causes the holder to move from an initial position to an operation position. When the holder is at the initial position, the separation member is spaced from a feeding member and is able to pass below the feed-out member. When at the operation position, the holder presses the separation member against the feeding member. When the sheet cassette is attached to the main body portion, the moving mechanism causes the holder to move to the operation position after the separation member passes below the feed-out member. When the sheet cassette is drawn from the main body portion, the moving mechanism causes the holder to move to the initial position before the separation member reaches below the feed-out member.

Abstract: A finishing system includes a piercing unit, an image reader, and a controller. The piercing unit includes a piercing member that performs piercing processing on a sheet.
