    摘要: In an acoustic wave filter, a notch resonator is connected in series (or parallel) with a plurality of acoustic wave resonators connected in a ladder shape. The notch resonator has a main resonant frequency that is substantially equal to a sub-resonant frequency of the acoustic wave resonators. With this configuration, the occurrence of sub-resonant responses in filter characteristics can be suppressed, resulting in an improvement in communication characteristics.

In order to achieve this object, magnetic substances which are radially extended with the sliding shaft at the center are provided in the lens holder, and the magnetic substances are located within a plane perpendicular to the plane constituting the magnetic gap and at the outside of the magnetic gap. Still further, in an objective lens driving device it is another object to prevent the occurrence of positional displacement of the objective lens due to resistance force of current supply means such as FPC. To achieve this object, a first objective lens and a second objective lens are arranged so that the objective lens arrangement angle at which the first and second objective lenses are arranged with respect to the shaft center of the sliding shaft is displaced, by a predetermined amount, from the magnetic circuit arrangement angle at which the magnetic substances and the magnets are arranged with respect to the shaft center of the sliding shaft.
