    • A fixing apparatus can prevent an excessive rise in temperature of a paper non-passage area due to diverted flow of magnetic flux from a paper passage area of a heat-producing element to a paper non-passage area thereof has a small configuration, A center core is rotated by a rotation section, bringing cutaway parts to a magnetic path masking position, and the degree of magnetic coupling between the center core and a heat-producing roller is weakened, suppressing an excessive rise in temperature of paper non-passage areas of the heat-producing roller. With this fixing apparatus, switching of the intensity of magnetic coupling between the center core and heat-producing roller can be performed simply by rotating the center core. Also, with this fixing apparatus, it is not necessary for magnetism suppressing elements to be provided as separate members, enabling the configuration to be made simpler and less expensive.

    • A sensor chip has a substrate and a comb-teeth electrode arranged on the substrate. The sensor chip is fixed to a diaphragm structure to be distorted by receiving pressure, and is fixed to the diaphragm structure only through a predetermined fix area so as to detect the pressure. The fix area is defined on only a part of the sensor chip opposing to the diaphragm structure. The sensor chip is restrained by the diaphragm structure in a direction of transmitting surface acoustic wave. Flexibility of the sensor chip in a perpendicular direction approximately perpendicular to the wave transmitting direction is larger than that in the transmitting direction.
