    Abstract: A head unit includes a common passage, at least one recording head, and a joint mechanism. The common flow passage has a liquid feed passage through which to pass at least one kind of liquid including ink. The recording head is attachable and detachable to and from the common flow passage, and has nozzles through which to eject the ink. The joint mechanism couples the liquid feed passage to a liquid feed port in the recording head, and has a first valve for opening and closing the liquid feed passage and a coupling member for coupling the first valve to the liquid feed port. In the top surface of the coupling member is a liquid reservoir portion for storing, when the recording head is removed from the common flow passage with the first valve closed, ink left between the first valve and the coupling member.

    Abstract: A sheet discharge device includes a discharge portion, a sheet stacking tray, a pair of alignment members and a pair of width regulation members, a shift portion, and a control portion. The pair of alignment members include an arm portion formed of a rigid body, and an alignment portion formed of a flat-shaped elastic material and fixed to a swingable end of the arm portion. In the sorting processing, when stacking a sheet at a first position, the control portion causes a first alignment member to ride on a top surface of the sheet and a first side edge of a second alignment member to make contact with the sheet, and, when stacking the sheet at a second position, causes the second alignment member to ride on the top surface of the sheet and the first side edge of the first alignment member to make contact with the sheet.

    Abstract: An inkjet recording apparatus includes a sheet conveyance portion, a pair of registration rollers, a recording portion, a plate portion, a suction roller, and an exhaust portion. The exhaust portion is disposed over an area from upstream of the recording portion to upstream of the pair of registration rollers with respect to the sheet conveyance direction and sucks air from above the conveyance belt and the plate portion in the direction away from the conveyance belt. The exhaust portion includes an exhaust hood and an exhaust fan. The exhaust fan guides the air in the exhaust hood through an air inlet into a recording potion housing and then passes the air through an exhaust outlet to discharge it via an air flow passage.

    Abstract: A medium conveying apparatus includes a driving roller, a plurality of driven rollers, a support part, a plurality of upstream restriction parts and a plurality of downstream restriction parts. The support part supports the driven rollers. The upstream restriction parts are provided in the support part between the adjacent driven rollers. The downstream restriction parts are provided in the support part between the adjacent driven rollers. The upstream restriction parts and the downstream restriction parts are arranged on an upstream side and a downstream side in a conveyance direction of the medium across a rotational center of the driven rollers respectively. When the driven rollers are tilted with respect to the conveyance direction, at least one of the upstream restriction parts and the downstream restriction parts comes into contact with side surfaces of the driven rollers to restrict tilting of the driven rollers.

    IPC: B41J2/14

    Abstract: A head unit includes a recording head, a head-side frame, a unit frame, a first head mounting member, a second head mounting member, a head angle adjustment mechanism, and an urging member. The unit frame is configured to hold the recording head on both side surfaces of a main frame standing along a width direction orthogonal to a conveyance direction of a recording medium. The urging member is arranged on a side opposite to an opposing surface of the first head mounting member and the second head mounting member with respect to the main frame, and is configured to urge the head-side frame in a direction of separating away from the main frame, A counteraction of a pressing force that acts on the head-side frame from the urging member acts on the first head mounting member and the second head mounting member from the head-side frame.

    Abstract: A head unit includes a recording head and a unit frame. The unit frame includes a main frame extending along a width direction orthogonal to a conveyance direction of a recording medium, and is configured to hold one or more recording heads on both side surfaces of the main frame. The main frame includes: a main body portion having a flat-plate shape and standing along the width direction; and bent portions formed by perpendicularly bending both end portions of the main body portion in the width direction. The unit frame includes a pair of reinforcing members provided at the bent portions. The reinforcing members each include a side wall portion opposed to the main body portion and a bottom surface portion provided so as to extend in a horizontal direction from a lower end portion of the side wall portion.
