摘要： A thermal printer (1) includes: a housing (2) including a roll sheet receiving portion (21); a cover (3) which is pivotably attached to the housing (2), and is configured to open and close the roll sheet receiving portion (21); a platen roller (40) which is rotatably supported on the cover (3) via a bearing portion (43A); and a thermal head (31) which is to be brought into press contact with an outer peripheral surface of the platen roller (40). The cover (3) includes a cover main body (50) and a base member (60) which is fixed to the cover main body (50). Directions orthogonal to an axial direction (D3) of the platen roller (40) and also orthogonal to each other are defined as a first direction (D1) and a second direction (D2), respectively. The cover main body (50) includes a first holding portion (51) which supports the bearing portion (43A) from one side in the first direction (D1). The base member (60) includes a second holding portion (62) which supports the bearing portion (43A) from the other side in the first direction (D1). The first holding portion (51) is located on one side in a second direction (D2) with respect to the bearing portion (43A), and includes a first claw portion (51a) protruding to the other side in the first direction (D1) along an outer peripheral surface of the bearing portion (43A). The second holding portion (62) is located on the one side in the second direction (D2) with respect to the bearing portion (43A), and includes a second claw portion (62a) protruding to the one side in the first direction (D1) along the outer peripheral surface of the bearing portion (43A). The first claw portion (51a) and the second claw portion (62a) face each other in the first direction (D1).

摘要： An image is printed on the front surface M1 by discharging the inks to the front surface M from the discharge heads 321 (first head) facing the front surface M1 (recording surface) of the printing medium M from above. Thus, the inks discharged from the discharge heads 321 partially become mist to possibly produce ink mist. Accordingly, the ink cover 51 (first cover) is arranged between the discharge heads 321 and the front surface M1 of the printing medium M before the discharge heads 321 discharges the inks to the printing medium M. By providing the ink cover 51 for the front surface M1 of the printing medium M before printing in this way, the adhesion of the ink mist to this front surface M1 can be suppressed.

摘要： A liquid discharge apparatus (1) includes a first liquid discharge unit (9A) including a first liquid discharge head (20) that moves in a main scanning direction to discharge a liquid onto a recording medium conveyed in a conveyance direction orthogonal to the main scanning direction, a second liquid discharge unit (9B) at a different position with the first liquid discharge unit (9A) in the conveyance direction and including a second liquid discharge head (20) that moves in the main scanning direction parallel to the first liquid discharge head (20) to discharge a liquid onto the recording medium, a first airflow generator (21) between the first liquid discharge unit (9A) and the second liquid discharge unit (9B) in the conveyance direction to generate an airflow flowing in the main scanning direction, and a partition plate (231) between the first airflow generator (21) and the second liquid discharge unit (9B) in the conveyance direction.

摘要： There are provided an ink refill container configured to appropriately refill an ink tank with ink and an ink refill system including such an ink refill container. An ink refill container 63 includes a container main body 64 provided to include an ink chamber 76; an ink outlet forming portion 66 provided at an edge of the container main body to include an ink outlet 65 configured to allow ink to flow out from the ink chamber; a valve 74 provided in the ink outlet forming portion and configured to seal the ink outlet in an openable and closable manner; and a positioning structure configured to abut on part of the ink tank and position the valve relative to the ink tank when the valve is opened. The positioning structure has a positioning surface 84 that is located on an opposite side to a container main body side where the container main body is located, across the valve and that is extended in a direction intersecting with a center axis 85 of the ink outlet.

摘要： A device includes a housing. The housing is capable of accommodating a recording unit (20). The recording unit includes a recording portion that performs recording on a medium, and a loading portion (49) on which a medium is loaded after recording is performed on the medium by the recording portion. The housing includes an extraction portion (70) that demarcates an extraction area (72) from which a medium loaded on the loading portion is removable. The extraction area is an area from which a medium loaded on the loading portion is removable from downstream in a discharge direction in which the medium on which recording is performed by the recording portion is discharged.
