摘要:
A paper feed unit includes a hopper on which sheets are stacked and which is turned around a rotation shaft. The hopper is turned to move apart from or move to a paper feed roller. The paper feed unit has three modes: a large release mode in which the hopper is turned to be most apart from the paper feed roller, a non-release mode in which the printing sheet is abutted against the paper feed roller, and a small release mode in which the printing sheet is slightly separated from the paper feed roller, and is at a medium level between the above two modes . When a paper feeding job is still present, a state that the uppermost printing sheet is slightly separated from the paper feed roller is retained by the small release mode, whereby a swing range of the hopper is minimized.

An ink jet recording apparatus includes a paper gap switching portion (200A) for switching paper gaps by moving a recording head (100), a pressing-force adjustment portion (200B) for applying a pressure to a following roller or release the pressure from the following roller (202) so as to adjust a pressing force applied to a recording medium, and an operation member (200G) for operating in series two series of driving operations including a driving operation for the paper gap switching portion and a driving operation for the pressing-force adjustment portion. Thus, the switching of the paper gaps and the adjustment of the pressing force can be performed only by operating the operation member (200G), and therefore they can be smoothly performed without fail, improving user's operability. Also, the adjustments of the recording head and the following roller can be performed simply and uniquely.
摘要:
Recording paper fed from a paper feed section comes in contact with a paper detection member (12) of a detector unit (8) and is rotated about a first fulcrum (35), shading the optical axis of an optical sensor (16). On the other hand, when the recording paper passes through and the paper detection member (12) is brought out of contact with the recording paper, the paper detection member (12) is restored to the former position by the urging force of an spring (37) and does not shade the optical axis. A carriage/cartridge detection member (15) of the detector unit (8) comes in contact with a carriage engagement part and a cartridge engagement part placed in a carriage and is rotated about a second fulcrum (43), shading the optical axis of the optical sensor (16). On the other hand, when the carriage/cartridge detection member (15) is brought out of contact with the engagement parts, the cordage/cartridge detection member (15) is restored to the former position by the urging force of an spring (44) and does not shade the optical axis.
