  • Publication number: 20170144456
    Abstract: A printer includes a print head, a platen roller, a frame, a release lever, and a spring. The print head performs printing on recording paper. The platen roller conveys the recording paper held between the platen roller and the print head. The print head and the platen roller are placed on the frame. The frame includes a side plate in which a frame groove is formed. The release lever moves relative to the frame. The spring is provided between the frame and the print head to urge the print head toward the platen roller. The platen roller is placed on the frame while being held between the frame groove and the release lever. The release lever moves to unblock the frame groove.

  • Patent number: 8711089
    Abstract: A position detection device includes an electromagnetic conversion element and a magnetic field generator. The electromagnetic conversion element is arranged on a given plane. The magnetic field generator is arranged facing one side of the electromagnetic conversion element in a direction vertical to the given plane and generates a magnetic field covering the electromagnetic conversion element. A relative position between the electromagnetic conversion element and the magnetic field generator is detected when a relative displacement parallel to the given plane is made by the electromagnetic conversion element and the magnetic field generator based on an output signal of the electromagnetic conversion element. The magnetic field generator has an opposed face that tilts to the electromagnetic conversion element, and generates the magnetic field from the opposed face.
