An inkjet recording apparatus (9) includes a recording head (7) and an ink circulation portion (8) including an ink storage container (100). The ink storage container (100) includes a main body portion (1), a lid portion (2), an ink inflow port (3), an ink outflow port (4), and a bubble discharge port (5). The ink circulation portion (8) includes a plurality of ink storage containers (100) for one recording head (7). The recording head (7) has a plurality of ink feed ports (70). The plurality of ink feed ports (70) are connected respectively to the ink outflow ports (4) of the corresponding ink storage containers (100) and feeds the ink flowing out through the ink outflow ports (4) of the corresponding ink storage containers (100) to the recording head (7).

A recording head (17a to 17c) includes an ink ejection portion (41) having a plurality of ejection nozzles (18) for ejecting ink and an ink reservoir (43) coupled to the ink ejection portion (41). The ink reservoir (43) includes an in-head flow passage (46) coupled to a common flow passage (40) for circulating ink, an air bubble separation portion (47) that separates air bubbles contained in ink flowing through the in-head flow passage (46), a valve member (50) that opens and closes an air bubble discharge port (47b) formed in a top part of the air bubble separation portion (47), and an ink discharge flow passage (48) extending downward from an ink inflow port (47a) formed in a lower end part of the air bubble separation portion (47) and coupled to the ejection nozzles (18) in the ink ejection portion (41). The in-head flow passage (46) is coupled substantially horizontally to the ink discharge flow passage (48) and a junction portion (52) between the in-head and the ink discharge flow passages (46, 48) is below the ink inflow port (47a).

A sheet post-processing apparatus (100) includes a discharge port (101), a discharge section (2), a discharge tray (T1), a processing tray (3), a folding section (1), a support member (5) that includes a support portion (50) supporting a part of a sheet (S) placed on the processing tray (3) from below, the part protruding via the discharge port (101) so as to be positioned above a discharge tray (T1), and that is movable between a protrusion position, at which the support portion (50) protrudes so as to be positioned above the discharge tray (T1), and a retraction position, at which the support portion (50) is retracted, and a control section (7). When newly loading a Z-folded sheet (Sz) onto the processing tray (3) in a state in which a sheet (S) is placed thereon, the control section (7) moves the support member (5) from the protrusion position to the retraction position.

When making a folding portion (1) perform a folding process, a control portion (3) drives the folding portion (1) and rotates a pair of first switchback rollers (11) forward. After the leading edge of a sheet (S) passes through a first switchback nip (SN1), the control portion (3) stops driving the folding portion (1) and stops rotating the pair of first switchback rollers (11) forward. The control portion (3) then starts rotating the pair of first switchback rollers (11) reverse and restarts driving the folding portion (1). When a slack part of the sheet (S) is drawn into a first folding nip (FN1), the control portion (3) first starts rotating the pair of first switchback rollers (11) reverse and then restarts driving the folding portion (1).

A packaging member (1) is formed by bending a single sheet material and includes a bottom plate portion (11), a first side wall portion (13), a second side wall portion (14), a top plate portion (12), and a support plate portion (21). The support plate portion (21) is connected to an end of the top plate portion (12) near the first side wall portion (13) in a second direction (D2) and is bent from the top plate portion (12) so as to be folded vertically downward toward the bottom plate portion (11), with a distal end thereof abutting against the article (P) to be packaged. The top plate portion (12) is bent along a first folding line (13b, 13c). The support plate portion (21) is bent from the top plate portion (12) along a second folding line (13a). The support plate portion (21) is positioned on an inner side relative to the first side wall portion (13) in the second direction (D2).

A punching device (PU) includes a punching member (1), a pin (2) that protrudes one end portion (21) and the other end portion (22) thereof in the second direction (D2) from the punching member (1), a holder (3) that is coupled to the one end portion (21) and the other end portion (22), and a guide (4) that accommodates the punching member (1). The guide (4) has pin insertion holes (40). The one end portion (21) and the other end portion (22) protrude to outside the guide (4) through the pin insertion holes (4). The holder (3) has a fitting hole (30), and the guide (4) is fitted into the fitting hole (30) such that the holder (3) is held so as to be movable along an outer circumferential surface of the guide (4). The fitting hole (30) has a recessed portion (31) that is recessed outward in a radial direction. The guide (4) has a protruding portion (41) that is positioned within the recessed portion (31).

The inkjet recording apparatus (100) includes a recording head (1), a cleaning member (2), and a container member (3). The container member (3) includes a containing part (31) which has an upwardly opening recessed area (310) and in which detergent supplied from above is contained in the recessed area (310), and a base part (32) which adjoins the containing part (31) in a first direction (D1) perpendicular to an up/down direction. The containing part (31) has a discharge hole (311) extending through the recessed area (310) in the up/down direction, and supplies the cleaning member (2) with the detergent flowing out downward from the discharge hole (311). An upper surface (32S) of the base part (32) is higher in liquid repellency to the detergent than an upper surface (31S) of the containing part (31).

The inkjet recording apparatus (100) includes a recording head (1), a cleaning member (2), a container member (3) which, by being pressed from above to below, is displaced from a first position to a second position and which, while in the second position, accepts supply of detergent, and a supply member (5) which is placed above the container member (3) to supply the container member (3) with the detergent. The container member (3) includes a containing part (31) for accepting supply of the detergent, and a base part (32) which adjoins the containing part (31) in a first direction (D1) perpendicular to an up/down direction. The supply member (5) presses the base part (32) from above to below without making contact with the containing part (31) so that the container member (3) is displaced from the first position to the second position.

The inkjet recording apparatus (100) includes a head unit (HU), a cleaning member (2), and a container member (3) which, by being pressed from above to below, is displaced from a first position to a second position, the container member (3) functioning in the second position to supply the cleaning member (2) with a detergent. The container member (3) includes a containing part (31) for containing the detergent, and a base part (32) which adjoins the containing part (31) in a first direction (D1) perpendicular to an up/down direction. The head unit (HU) has a head base (11), and the head base (11) presses the base part (32) from above to below without making contact with the containing part (31) so that the container member (3) is displaced from the first position to the second position.
