Abstract: A base board includes a board and a controller mounted on the board. A controller is configured to receive signals outputted from a first sensor and a second sensor. A recording head, a case, the first sensor, a maintenance unit, a waste liquid container, the second sensor, and the base board are arranged in an internal space of a housing. The base board has a flat surface extending in a first horizontal direction and in a second horizontal direction. A range occupied by the base board in a vertical direction overlaps each of a range occupied by the first sensor in the vertical direction and a range occupied by the second sensor in the vertical direction. The second horizontal direction is perpendicular to the first horizontal direction. The vertical direction is perpendicular to both the first horizontal direction and the second horizontal direction.

Abstract: A liquid cartridge includes a housing, a circuit board including an electrode, and a liquid supply portion extending from the housing in a depth direction. The housing includes a top wall, and first and second protrusions protruding upward from the top wall. The first protrusion is positioned rearward but the second protrusion is positioned frontward relative to the circuit board. The first protrusion is higher than an upper edge of a front end of the second protrusion. No part of the liquid cartridge is positioned higher than an imaginary plane in a height direction in a region between a first point on the first protrusion and a second point on the second protrusion (the upper edge of the front end of the second protrusion) in the depth direction. The imaginary plane passes through the first and second points, and extends perpendicularly to the depth direction.

Abstract: An image-recording apparatus includes: a first tank defining a first storage chamber; a second tank defining a second storage chamber; a conveying mechanism for conveying sheets along a conveying path extending in a depthwise direction and a widthwise direction perpendicular to a vertical direction and the depthwise direction; and a recording head including a nozzle. Liquid in the first storage chamber is supplied through a communication port to the second storage chamber and then to the recording head through a liquid outlet port. The second storage chamber is positioned further in a first depthwise direction relative to the nozzle and further in a first widthwise direction relative to the conveying path. A volume of a prescribed space above a liquid level equal to a height of the communication port in the second storage chamber is greater than that of a liquid channel between the liquid outlet port and the nozzle.

Abstract: An inkjet printer further includes a printer main body, and an ink-accommodation unit including a first member and a second member. The first member is configured to accommodate ink to be supplied to the printer main body. The first member includes an injection portion for injection of ink. The second member is pivotably movably connected to the first member. The second member is pivotable relative to the first member between a closed position and an open position. When the second member is at the closed position, the injection portion is covered by the second member. When the second member is at the open position, the injection portion is exposed. Here, an axis of the pivot is parallel to a front-rear direction of the first member, and is positioned at a side of the first member, the side being closer to the printer main body.
