Description l Title of the invention! 411. A pick-up cartridge having a configuration in which a
magnet magnetized in the longitudinal direction of the sensing lever is positioned at the center
position of the armature and on or above the center axis of the player.
3. Detailed Description of the Invention The present invention seeks to provide a pickup cartridge
having a novel configuration. The details of one embodiment of the present invention will be
described below with reference to the drawings. It is a pickup cartridge of the invention. And, as
for the constitution, the magnet 1B magnetized in the longitudinal direction of the sensing lever
1 is provided on the central axis of the amateur at the center position of the wfz 10 formed on
the lever 1 . In this case, it is preferable to position it above the armature and to have a pipe-like
body 1c made of a magnetic material or a rod-like body 1c '. Further, this pipe-shaped body or an
amateur body ID corresponding to the rod-shaped body 10 ', 11 having a flat-plated body 01F
has a film 111' with a sulfo- # piece, and the magnet IB is fixed. The space is supported by a
space -1e. And 11 is a damper which is interposed between magnets. Further, the abovementioned amateur body ID, 1 m is a circular one even in a circular ID "11 °". One thing (11) is
OK. It may be V-shaped In (1 m). EndPage: Since the book of the present invention is configured
as described above, it is magnetized in the longitudinal direction of the armature by the magnet,
and the magnetic flux between the pole piece and the armature changes, and the pole piece Kl!
An output is produced by the retarder coil. Therefore, as shown in FIG. 8, a conventional so-called
IM cartridge 2 (in the figure, 2 indicates a pole piece, 2B indicates a coil, 20 indicates an f lever,
2T3 indicates an amateur, 21C indicates a sensing lever, and 2F indicates a magnet. Because the
distance I between the amateur and the magnet can be made extremely short compared to the
above, and also the magnet can be made compact, the weight of the whole cartridge can be made
light and inexpensive, and both the K and the tracing ability can be improved. It can be done.
Furthermore, since the center of the magnetic field and the center of gravity of the vibration
system are at the same position or very close to each other, the same operation is performed for
the N8 magnetic pole, there is little distortion in the reproduction and waveform, and good
crosstalk characteristics. can do.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view, FIG. 2 is a crosssectional view of another embodiment, and FIG. 3 is a front view of an amateur body. FIG. 5 is
also a sectional view of another embodiment, FIG. 6 is a front view of an armature, and FIG. 8 is a
sectional view of a conventional one. 111. Pickup cartridge, one person ,,. Sensing lever, lB ,,,
