Abstract: An image reading device has an optical unit and a rail portion formed of sheet metal. The optical unit is scanned in the sub scanning direction to read an image on a document on a contact glass. The rail portion slidably supports the optical unit. The optical unit has a sliding portion which slides on the rail portion while making contact therewith, and at least one pair of gripping portions which grip the rail portion. The surface of the sliding portion has a substantially arc-shaped cross section. The rail portion has two inclined surfaces that make contact with the substantially arc-shaped surface at two points.

Abstract: A cleaning device includes a cleaning unit and a unit moving mechanism. The cleaning unit brings a web into contact with a conveyance member rotating around an axis and removes foreign matter adhered to the conveyance member. The unit moving mechanism displaces the cleaning unit to a cleaning position where the web is brought into contact with the conveyance member and to a separation position where the web is separated away from the conveyance member. When the unit moving mechanism displaces the cleaning unit from the cleaning position to the separation position, the cleaning unit is displaced in a counter direction opposite to a rotational direction of the conveyance member on a contact face between the conveyance member and the web.

Abstract: An inkjet includes a head unit, a blade, and a cleaning liquid supply member. The head unit is provided with a nozzle surface, and supported to be lifted and lowered. The blade is in contact with the nozzle surface and moves in a predetermined moving direction to wipe off the nozzle surface. The cleaning liquid supply member stores a cleaning liquid, and supplies the cleaning liquid between a moving start position of the blade and the nozzle surface. The cleaning liquid supply member has a plurality of supply ports provided between the moving start position of the blade and the nozzle surface. When a direction crossing to the moving direction is defined as a width direction, a width of the blade is set to “a”, and a width of a region where the supply ports are formed is set to “b”, then the next formula is established, a≤b.

Abstract: An inkjet recording apparatus includes a recording head, a blade, and a cleaning liquid supply member. The head unit is provided with a nozzle surface. The cleaning liquid supply member includes a supply port, a sheet member, and a holder. When the cleaning liquid supply member is moved to a supply position and then the recording head is lowered, a tip end of the sheet member comes into contact with the nozzle surface, and then the cleaning liquid supply member is turned from an inclined posture to a supply posture while the tip end of the sheet member is moved along the nozzle surface forward in the moving direction, and the sheet member is disposed between the supply port and the nozzle surface.

Abstract: A conveying roller has a rotary shaft portion, a roller supporting member, and a roller member. The rotary shaft portion is extendable/contractible. The roller supporting member has an interior space. The roller member is supported on the outer circumferential surface of the roller supporting member. The rotary shaft portion includes first and second shafts. The first shaft has one end part inserted into the interior space, and is movable axially relative to a first side surface. The first shaft has a regulating portion displaceable between a permitting position where the regulating portion permits the movement of the first shaft in the insertion direction relative to the roller supporting member without interfering with a rim of an opening and a restricting position where the regulating portion restricts the movement of the first shaft in the insertion direction relative to the roller supporting member by interfering with the rim.

Abstract: A detection system includes a detection target device and a detection device. The detection target device includes a first rotating member rotatable about a first axis, and repeats an operation corresponding to a rotation angle of the first rotating member every time the first rotating member makes a 1/N rotation, N being an integer of 2 or greater. The detection device includes a second rotating member rotatable about a second axis due to a driving force transmitted from the first rotating member, and an output value of the detection device repeats monotonic increase or monotonic decrease in accordance with a rotation angle of the second rotating member every time the second rotating member makes 1 rotation. Every time the first rotating member makes a 1/N rotation, the second rotating member makes 1 rotation.
