RECORDING APPARATUS CAPABLE OF DETECTING RESIDUAL AMOUNT OF INK IN INK CARTRIDGE |
摘要 |
A recording apparatus includes a controller and a cartridge accommodating section in which an ink cartridge of a predetermined type is mountable. The ink cartridge includes: an ink chamber; a first heat conductor that conducts heat to the ink; a pyroelectric portion that outputs an electrical signal; and a first electrical interface that connects to the pyroelectric portion. The cartridge accommodating section includes: a second electrical interface that connects to the first electrical interface when the ink cartridge is mounted in the cartridge accommodating section; a heater that applies heat; and a second heat conductor that conducts heat to the first heat conductor. The controller determines at least one of the type of the mounted ink cartridge and whether an amount of ink in the ink chamber is less than a predetermined amount based on the electrical signal inputted from the pyroelectric portion via the second electrical interface.
