Abstract: The present invention provides an ink jet printing apparatus capable of improving reliability of an electrical connecting portion between a carriage side and head cartridge side. When an ink tank is mounted on a head cartridge, a hook of a set lever is obstructed to be operated in a lock releasing direction by a restricting surface of the ink tank. This prevents the head cartridge from being removed from the carriage, and maintains an electrical connecting condition between the carriage and the head cartridge. Therefore, for removing the head cartridge, it is necessary to remove the ink tank.

Abstract: First humidified gas is supplied from a first supply port to a sheet to be conveyed, thereby increasing the moisture content of the sheet. Simultaneously, second humidified gas is supplied to a space where nozzles of the inkjet recording head are exposed, from a second supply port provided at a position closer to the inkjet recording head than the first supply port, thereby increasing the atmosphere humidity of the space. The part of the sheet of which the moisture content has been increased is made to enter the space where the atmosphere humidity has been increased, and recording is performed by the inkjet recording head.

Abstract: A sheet feed tray is openably/closably (or foldably) attached to the main body of a recording apparatus, and a separator, which separates recorded media to be discharged above the sheet feed tray from unrecorded media loaded on the sheet feed tray, is provided so as to be displaceable relative to the sheet feed tray. When the sheet feed tray is pivoted a predetermined distance or more in the direction indicated by an arrow A, the separator is turned in the direction indicated by an arrow B and enters the inside of the sheet feed tray. With the arrangement, the interference between a separator and the main body of a recording apparatus is avoided, without causing a reduction in the permissible number of unrecorded media to be loaded and an increase of the size of the apparatus.
