  • Patent number: 11927466
    Abstract: A physical quantity measurement device is configured to seal a cavity portion on a back surface side of a diaphragm of a thermal air flow rate sensor while improving measurement accuracy. The device may include a lead frame having a mounting surface on which a flow rate sensor which is the thermal air flow rate sensor is mounted, and a flow passage forming member disposed on a back surface opposite to the mounting surface of the lead frame. A ventilation flow path is formed by a first through hole in communication with a cavity portion of the flow rate sensor, a second through hole provided in the lead frame and opened in the mounting surface, and a connection flow path that is defined between the lead frame and the flow passage forming member and connecting the first through hole and the second through hole.

  • Patent number: 10618324
    Abstract: A printing apparatus includes a plurality of belt rollers that rotate, a direction in which a rotation axis of each belt rollers extends being a width direction that intersects a transport direction of a medium; a transporting belt that, while wound across the plurality of belt rollers, rotate to transport the medium in the transport direction; a print head that performs printing on the medium transported by the transporting belt; and a control unit that rotates the transporting belt while in a state in which an unrotated state of the transporting belt has continued for a predetermined period. When a rotation position of the transporting belt after application of power and before rotating the transporting belt is referred to as an initial rotation position, in a case in which a rotation of the transporting belt is to be stopped, the control unit stops the transporting belt at a rotation position that is different from the initial rotation position.

  • Patent number: 10362404
    Abstract: A frame is coupled to a magnetic circuit. The frame includes a plurality of holes which are formed outside the coupling portion and opened toward the magnetic circuit. A case covers the magnetic circuit and the frame, and is opened on a sound radiation direction side. An outer circumferential portion of the case is located on the sound radiation direction side beyond the plurality of holes and forms a first gap with respect to the frame. The first gap is communicated with an opening of the case.

  • Patent number: 10343422
    Abstract: A recording apparatus includes a belt conveyor unit that can be switched between a first state in which at least a portion of the belt outer surface of a conveyor belt is located at a recording position at which a line head performs recording and a second state in which the belt outer surface is located more distant than the recording position from the line head. The recording apparatus also includes a wiping device that is in contact with the belt outer surface and wipes the belt outer surface. The belt conveyor unit is switched from the second state to the first state after carrying out of a preliminary operation in which the conveyor belt is moved over a predetermined distance in a reverse direction opposite to a normal direction in which the conveyor belt transports a sheet.

  • Patent number: 9789716
    Abstract: An ink jet printer includes a cleaning blade that cleans the surface of a transport belt that attracts a sheet of recording paper by electrostatic adsorption and transports the attracted recording paper, and a pressing roller. The width of the cleaning blade is smaller than the width of the pressing roller that is located downstream of the cleaning blade, and thus, ink, paper dust, and the like that have escapes from both ends of the cleaning blade to the outside and have not been wiped off are caught by the pressing roller.
