Abstract
In an ink jet printer, a recording unit in which an ink cartridge is detachably mounted has a cartridge removal preventing member so that the ink cartridge is prevented from being carelessly removed therefrom, and a moving mechanism is provided which, when the recording unit is mounted on the carriage, moves a first electrical connecting section towards a second electrical connecting section so that the first and second electrical connecting section are connected to each other with the aid of an energizing member under pressure, and, when the recording head is removed from the carriage, moves the first electrical connecting section away from the second electrical connecting section against the elastic force of the energizing member, whereby the recording head is detachably mounted on the carriage, and the former is positively electrically connected to the latter.
