Abstract: An image-recording apparatus includes a cartridge including a first storage chamber, a tank including a second storage chamber, a recording portion for ejecting liquid stored in the second storage chamber, a detected portion, and a detector. The first and second storage chambers can communicate with an atmosphere. The tank includes a liquid inlet port and a liquid outlet port positioned lower than the liquid inlet port. Liquid in the first storage chamber is supplied to the second storage chamber through the liquid inlet port, and from the second storage chamber to the recording portion through the liquid outlet port. The detected portion can change in state when a level of the liquid stored in the second storage chamber becomes equal to a vertical position of the liquid inlet port. The detector is configured to detect the change in state of the detected portion.

Abstract: In a state where a supply portion of a cartridge is connected to a connecting portion of a cartridge attachment section, a first base part and a first protruding part of the cartridge and a second base part and a second protruding part of the cartridge attachment section have the following positional relationship: as viewed in the horizontal direction, the first base part is overlapped with both of the second base part and second protruding part, the first protruding part is overlapped with the second base part, but is not overlapped with the second protruding part; and as viewed in the vertical direction, the first base part is not overlapped with the second base part, and is not overlapped with the second protruding part, and the first protruding part is overlapped with the second protruding part, but is not overlapped with the second base part.

Abstract: An image recording apparatus includes: a cartridge; a cartridge attachment portion; and a switching portion. The cartridge includes: a first storage chamber; a first air communication portion; and a first supply portion. The cartridge attachment portion includes: a second storage chamber; and a second air communication portion. The switching portion changes a passage resistance value of air flowing through one of the first and second air communication portions. An inequality of R2>A×R1 is met, in which R1: a passage resistance value obtained by air flowing through the first air communication portion and a passage resistance value of the liquid flowing through the first supply portion; R2: a passage resistance value of air flowing through the second air communication portion; A: a cross-sectional area ratio obtained by dividing an average cross-sectional area of the first storage chamber by an average cross-sectional area of the second storage chamber.

Abstract: In an inkjet type image forming apparatus, a cartridge includes a first storage chamber and a first fluid communication portion. The first air communication portion allows the first storage chamber to be in communication with an atmosphere. A second storage chamber stores the ink supplied from the first storage chamber by hydraulic head difference. The switch portion switches a state of the second air communication portion between a first state in which the second storage chamber communicates with the atmosphere and a second state in which an amount of air flow between the second storage chamber and the atmosphere is smaller than that in the first state. The controller controls the switch portion to switch the state of the second air communication portion from the first state to the second state. After the recording process, the controller controls the switch portion to switch the state to the first state.

Abstract: For an image forming apparatus including first and second storage chambers, an inequality expression of “R2>A×R1” is met. R1 is a sum of a passage resistance value obtained by flowing air through a first air communication portion and a passage resistance value obtained by flowing liquid through a supply portion. R2 is a passage resistance value obtained by flowing air through a second air communication portion. A is a cross-sectional area ratio obtained by dividing a first average cross-sectional area of a first space of the first storage chamber taken along a plurality of horizontal planes by a second average cross-sectional area of a second space of the second storage chamber taken along the plurality of horizontal planes. The first space contains at least a portion adjacent to the supply portion and accumulating the liquid. The second space contains at least a portion accumulating the liquid.

Abstract: An image-recording apparatus includes a cartridge including a first storage chamber and a first air communication portion, a cartridge-attachment portion including a second storage chamber and a second air communication portion, a switching portion, and a controller. The second storage chamber stores liquid supplied from a supply portion of the cartridge connected to a connecting portion of the cartridge-attachment portion through a liquid outlet port. The switching portion switches the second air communication portion between a first state and a second state. An air flow rate through the second air communication portion per unit of time is lower in the second state than in the first state. The controller determines the liquid level of liquid in the first storage chamber and switches the switching portion to the second state when the liquid level in the first storage chamber is lower than a vertical position of the liquid outlet port.

Abstract: In an image forming apparatus, a cartridge includes: a first storage chamber; and a supply portion. A cartridge attachment portion includes: a connecting portion; and a second storage chamber. The connecting portion is disposed at a first height and connectable to the supply portion. A detecting portion is configured to detect one of a level of a liquid stored in the first storage chamber and at a position adjacent to the supply portion and a level of the liquid stored in the second storage chamber and at a position adjacent to the connecting portion. The first storage chamber has a first cross-sectional area taken along a horizontal plane at a predetermined height between the first height and a second height above the first height. The second storage chamber has a second cross-sectional area taken along the horizontal plane. The second cross-sectional area is greater than the first cross-sectional area.

Abstract: An inkjet printer includes a main body. An ink containing unit is disposed in the main body and is configured to contain ink to be supplied. The ink containing unit includes an ink refill portion through which ink is refilled and an ink level display surface disposed on a side surface of the main body. The side surface has an opening through which a jammed sheet is removed and a first cover configured to cover the opening. The ink level display surface and the first cover are juxtaposed on the side surface in a horizontal direction.

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.
