摘要： An ink jet recording apparatus and method having an ink jet head. The ink jet head includes a housing made of a material having a high coefficient of thermal conductivity, including at least one heat source, and arranged so as to confront a recording medium; an ink holding member arranged inside the housing, the ink holding member transmitting heat generated by the heat source to melt a solid-phase ink put into the housing for holding the molten ink by capillary action; a nozzle formed member being part of the ink holding member and having at least one nozzle orifice arranged so as to confront the recording medium; and a pressure generating member arranged within the ink holding member for generating a pressure which causes ink near the nozzle orifice to jet in the form of ink drops. The ink jet recording method is achieved by the apparatus thus constructed.

摘要： Recording paper fed from a paper feed section comes in contact with a paper detection member of a detector unit and the paper detection member is rotated about a first fulcrum, shading the optical axis of an optical sensor. When the recording paper passes through and the paper detection member is brought out of contact with the recording paper, the paper detection member is restored to the former position and does not shade the optical axis. A carriage/cartridge detection member of the detector unit comes in contact with a carriage engagement part and a cartridge engagement part placed in a carriage and is rotated about a second fulcrum, shading the optical axis of the optical sensor. When the carriage/cartridge detection member is brought out of contact with the engagement parts, the carriage/cartridge detection member is restored to the former position and does not shade the optical axis.
