Abstract: A coupling/uncoupling device includes a columnar member configured by a divided pair of semicircular members, and a pair of coupling members forming a circular holding section that holds the columnar member. The circular holding section includes a circular inner surface section with which an outer circumferential surface of the columnar member is in slide contact, the circular inner surface section being formed from inner circumferential surfaces of a semicircular section in one coupling member and a semicircular section in the other coupling member. The columnar member is configured to be rotatable in both clockwise and counterclockwise directions along the circular inner surface section about a reference position where a contact surface of the pair of coupling members and a dividing surface of the columnar member are flush with each other.

Abstract: A case structure forms a storage space for a first electronic component. The case structure includes a plurality of support posts that are disposed parallel to each other; and a plurality of panels that is provided among the plurality of support posts, the plurality of panels constituting outer walls. At least one panel of the plurality of panels is a panel having an outer surface on which a second electronic component provided, the second electronic component being connected with the first electronic component, and the plurality of panels is attached to the plurality of support posts in a detachable manner along a longitudinal direction of the plurality of support posts.

Abstract: An ink jet recording apparatus performs a print operation by controlling an ink jet recording head to eject ink drops there from against front and back surfaces of a recording sheet at a print position. The apparatus includes a transporting mechanism for transporting a portion of the recording sheet to a location outside of the apparatus after a completion of the print operation on the front surface of the recording sheet and just before printing of the back surface of the recording sheet.
