BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of
a movable electrode support structure according to the present invention, and FIG. 2 is a front
view showing an essential part of the same.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a capacitor pickup cartridge, and in particular to the improvement of a movable electrode support assembly.
Conventionally, in a capacitor pickup cartridge, a movable electrode support structure for
supporting a movable electrode on a cantilever has one end of a movable electrode support of an
armature formed of, for example, a metal wire fixed to the cantilever by brazing or the like In
general, the movable electrode is fixed to the other end of the support. However, it is difficult to
stably fix and bond this armature to the cantilever because such a movable electrode support
structure has a minute portion for fixing the movable electrode support and the cantilever by
brazing or the like. Also, since metal is used as the movable electrode support, the vibration
frequency of the cantilever matches the natural frequency of the movable electrode support or
the movable electrode itself, and there is a high risk of resonance and abnormal vibration of the
movable electrode [111111] Was apt to occur. An object of the present invention is to eliminate
the above-mentioned drawbacks and to provide a movable electrode support structure capable of
fixing the movable electrode support and the cantilever extremely stably and in which abnormal

vibration does not occur in the movable electrode. An embodiment of the movable electrode
support structure of the present invention will be described below with reference to the
drawings. That is, as shown in FIG. 1, the rear end of the cantilever 13 having the record needle
12 fixed at its tip is swingably supported by the damper 11 of the capacitor pickup cartridge, and
the cantilever 13 has a movable electrode 15.15. A movable electrode support 16 is provided.
Thus, as shown in FIG. 2, the movable electrode support 16 continuously and integrally has a
substantially semicircular shape of the circumferential surface of the cantilever 13! It has a
substantially triangular prism shape made of an elastic polymer material such as rubber having a
recessed groove 14 provided at the bottom and a movable electrode 15.15. The movable
electrode support 16 is mounted and fixed at a predetermined position on the cantilever 13 such
that the cantilever 13 is fitted by the concave groove 14. In this case, any one of the side surfaces
of the movable electrode support 16 is the bottom surface, and the movable electrodes 15.15 are
respectively provided at predetermined positions on two side surfaces other than the bottom
surface. . Therefore, according to such a movable electrode support structure, a concave groove
14 to which the cantilever 13 can be fitted is provided in the movable electrode support 16
portion to which the cantilever 13 is fixed, and the concave groove 14 is formed with the
cantilever 1. By fitting 3, the movable electrode support 16 and the cantilever 13 can be fixed
very stably and easily.
Also, by using an elastic polymer material such as rubber for the movable electrode support 16,
the resonance of the cantilever 13 and the movable electrode support 16 occurs due to the
properties such as the buffer action accompanied by the loss of the elastic polymer material.
Anomalous vibration of the movable electrode 15 [deg.] 15 resulting from the like can be almost
prevented. [111111] EndPage: 1 In the above embodiment, although the movable electrode
support structure for stereo has been described, the present invention is not limited to this and
can be used also for an apparatus similar to this. Further, since this movable electrode support is
for stereo, the case where it is formed into a substantially triangular prism has been described,
but it is needless to say that the shape is not limited to this shape. As described above in detail,
according to the present invention, it is possible to provide a movable electrode support structure
in which the movable electrode support and the cantilever can be extremely stably and easily
fixed and no abnormal vibration occurs in the movable electrode [ 111111]
