Abstract: A return spring is constituted of a torsion spring, a spring part is held at a position different from that of a shaft part of a flyweight, and a free end portion of the return spring is hooked to a slide unit of the flyweight. The position of transmission of an urging force to be transmitted from the return spring to the flyweight is different between an angle-closing side and an extending and opening side. By tuning the shape of the slide unit, the position of protrusion of a spring fixing pivot, or the like, the distance from the shaft part to a contact point of the free end portion when the flyweight is located at the angle-closing position is set to be larger than the distance from the shaft part to the contact point of the free end portion when the flyweight is located at the extending and opening position.

Abstract: In a recording apparatus, a recording operation is controlled by being connected to a host computer. The apparatus includes a sheet supporting unit for supporting a plurality of sheets, a feeding unit for feeding a sheet supported by the sheet supporting unit, a manual insertion port for manually inserting a sheet into the main body of the apparatus, a conveying unit for conveying the sheet fed from the sheet supporting unit or the sheet inserted from the manual insertion port, a recording unit for performing a recording operation on the sheet fed by the conveying unit, a sheet detection unit for detecting the sheet inserted from the manual insertion port, and a control unit for causing the apparatus to execute a recording operation in a manual insertion mode based on the detection of the manually inserted sheet by the sheet detection unit, and for temporarily providing an off-line state with respect to the host computer after the recording operation has been completed.

Abstract: A recording apparatus effects a recording operation by scanning a recording medium in a predetermined direction with a recording head provided with discharge openings for recording liquid. A cap member is capable of covering a face with discharge openings of said recording head. A transmission member causes said cap member to cover said face with discharge openings in response to a motion setting said recording head to a predetermined position; and engaging members consisting of a protruding part are provided on one of said recording head and a carriage supporting said head. The protruding part engages a receiving part for said protruding part formed on the other of said recording head and said carriage, wherein said protruding part and said receiving part mutually engage at two points when said cap member covers said face with discharge openings.
