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.
