Image-recording apparatus including wall portion provided in storage chamber of tank connectable to liquid cartridge

An image-recording apparatus comprising:

• a cartridge comprising:
• a first storage chamber configured to store liquid;
• and
• a first air communication passage configured to allow the first storage chamber to communicate with an atmosphere;
• a tank connectable to the cartridge and comprising:
• a liquid inlet port through which the liquid stored in the first storage chamber is configure to be introduced;
• a second storage chamber configured to store the liquid introduced thereinto from the first storage chamber through the liquid inlet port;
• a liquid outlet port configured to discharge the liquid stored in the second storage chamber to flow out therefrom;
• and
• a second air communication passage configured to allow the second storage chamber to communicate with the atmosphere;
• a recording portion comprising a nozzle through which the liquid supplied from the second storage chamber through the liquid outlet port is configured to be ejected in a form of liquid droplets;
• a detected portion disposed in the second storage chamber, the detected portion being configured to change in state in a case where a liquid level of the liquid stored in the second storage chamber becomes equal to or lower than a position of the liquid inlet port in a vertical direction;
• a detector configured to detect change in state of the detected portion and output a detection signal upon detection of the change;
• and
• a wall portion partitioning an inner space of the second storage chamber into a first region and a second region, the liquid inlet port being provided in the first region and the detected portion being provided in the second region, the wall portion extending from a position upward relative to the liquid inlet port and the detected portion to a position downward relative to the liquid inlet port and the detected portion in the vertical direction, the first region and the second region being allowed to communicate with each other through an upper communication portion and a lower communication portion, the lower communication portion being formed in a lower end portion of the wall portion in the vertical direction, the upper communication portion being positioned upward relative to the liquid inlet port, the detected portion and the lower communication portion.
