摘要： A circular surface of a magnet is magnetized to an N-pole, and a back surface is magnetized to an S-pole. A detection unit moves in an X-Y plane at a position apart from the surface of the magnet. An X-direction detection element and a Y-direction detection element are installed in the detection unit. Both the X-direction detection element and the Y-direction detection element are magnetoresistive effect elements each having the bias magnetic field in a B-direction applied to a free magnetic layer directed perpendicular to the surface of the magnet. Each bias magnetic field is stabilized both in the X-direction detection element and the Y-direction detection element such that the detection unit accurately provides position detection output values in the X- and Y-directions.

摘要： A circular top surface of a magnet is magnetized to the N-pole, and a back surface thereof is magnetized to the S-pole. A detector moves within the X-Y plane at positions located away from the top surface of the magnet. A pair of X-direction detecting elements and a pair of the Y-direction detecting elements are provided in the detector. In the X-direction detecting elements, the directions of a bias magnetic field provided to free magnetic layers are opposite to each other. When the detector moves in the Y direction, a decrease in the sensitivity of one of the X-direction detecting elements is compensated for by an improvement in the sensitivity of the other element. This also applies to the Y-direction detecting elements. Accordingly, position detection outputs of the X direction and the Y direction can be accurately obtained from the detector.

摘要： A rotation unit is supported to a device main body unit so as to rotate about a rotation supporting point. The rotation unit is rotated from a closure posture close to the device main body unit until a rotation limit position at 180 degrees. A magnet is fixed to the rotation unit at a position away from the rotation supporting point, and the device main body unit is provided with a detector capable of distinctly detect magnetic fields in two directions. When the rotation unit is rotated from the closure posture at a predetermined angle, a first open detection output is obtained form the detector and a display unit provided to the rotation unit is turned ON. The rotation unit is further rotated and when a second open detection output is obtained from the detector, the display content of the display unit is switched to be turned upside down.

摘要： A thermal head includes a head substrate having a plurality of heating resistors which generate heat by electrical dissipation, a common electrode connected to one end of each heating resistor, and a plurality of individual electrodes connected to the other ends of the respective heating resistors. The head substrate is disposed on a heat-dissipation plate. A wide-gap stepped portion is disposed in correspondence with at least a location of the head substrate directly below the heating resistors, and increases an interval between an adhesion surface of the head substrate and an adhesion surface of the heat-dissipation plate. A resilient adhesive capable of absorbing thermal strain is interposed between the adhesion surface of the heat-dissipation plate and the adhesion surface of the head substrate in an adhesion plane where the wide-gap stepped portion is disposed.
