DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement
of a pickup for reproducing an Ify signal in contact with a recording medium (generally called a
video disc) formed by engraving and recording a wide band signal such as a cinematic signal, in
particular The present invention relates to a pickup that is devised to derive an electric signal
taken out to an electrode of a pressure sensitive element, and that is responsible for the
characteristics of the pickup and its fabrication to the same as fabrication. In order to derive the
electrical signal generated at the electrodes of the pressure-sensitive element, generally, a
method of soldering a metal wire directly to the Fi-sensitive pressure-sensitive insulator silverplated electrode is employed, but in this case solder and metal The wire acts as a load on the
pressure sensitive element and its load differs depending on the non-uniformness of the
operation. Therefore, it has not been avoided that the frequency characteristics of the pressure
sensitive element deteriorate or become uneven. In addition, the cutting needle of the video disc
adheres to the reproduction needle while traveling on and off the video disc made of, for
example, polyvinyl chloride. If this cutting mark sticks, it will deteriorate the followability of the
regenerating needle, so it is necessary to carry out cloning of the cut 11 at an appropriate
opportunity. However, as described above, when the sound S edge is soldered directly to the

electrode of the pressure sensitive element, the gold jj I 11! Because there is a risk of accidentally
cutting the gold R line during surface cleaning where iI is branching, the gold stripping line of Z
is connected to the electrode of the pressure-sensitive element whose one side is 100 μ or less.
It is thin, and it receives an external impact at any time other than the above-mentioned IJ-Jung,
that is, it is broken even when it is running. Therefore, in order to output the electric signal t-S
from the electrode direction of the pressure-sensitive element, it is preferable that the gold
outline is not used at least in the vicinity of the regenerating needle. The present invention
proposes a novel pick-up 3 that responds to the belts of the present invention, and will be
described below with reference to the drawings. tJg1 (a) ~ (c) shows an embodiment of the
pickup according to the present invention, IKI (a) is a front view thereof, 1jfi (b) is a side view,
and eile (a bottom view, same view) − Is an oblique view of the holder constituting the present
pickup. In each figure 2 etc., (1) corresponds to the reproduction needle pressed against the
wavelike signal convex part engraved and recorded on the video disc along the groove of the
video disc, (2) corresponds to the vibration picked up by the # reproduction needle Pressuresensitive elements for converting into electric signals, (31 (31 are electrodes facing each other of
the pressure-sensitive elements (2), (4) (4) Fi, for example, a pair of conductive plates made of
phosphor bronze or other metal body, (5 companies: insulating member interposed between
these conductive plates, (6) is a buffer which is housed in a space formed by the base plate
conductive plate and the insulating member and is fixed to the insulating member (5), (7 × 71
For example, a conductive silver coating 47941 made of Dupont is used as an elastic conductive
member which respectively connects the electrodes (, 1 × 3) of the pressure sensitive element to
the conductive plate (n × 4) KW.
(8M8) if shows an adhesive having elasticity, for example, a silicone rubber adhesive, for
retaining the conductive member. As shown in FIG. 1 (b), the @ U-grid conductive plate (41 (4)
and the e-clearing member (5+) have the function of a holder in the conventional pickup. In the
case of this embodiment, the electrical signal generated at the electrode of the pressure sensitive
element is taken out through the elastic conductive member (7) and the conductive plate (4).
Therefore, it is possible that the electrical signal be ejected from the lead a position to be
connected to the required circuit all the time from the regenerating needle (1), for example, from
the other end of the holder (the conductive plate (4) forming the base). it can.! p! Fig. 2 (a) to
(c) show another embodiment of the pickup according to the present invention, and Fig. 2 (a) is a
front view of the main part, Fig. 2 (crying is a side view, Fig. 2 3) is a bottom view of the same,
and FIG. 3 (c) is a perspective view of a support which constitutes the main part of this
embodiment. In the present embodiment, except that the supporting base αO consisting of the
insulating member (5) and the conductive plate (4) (4) interposed between the insulating
member (5) and the supporting member @ is configured separately, It is almost the same as the
example. Therefore, in the case of the present embodiment, conventionally known ones can be
used as the holder. At that time, the electric signal generated at the electrode of the pressure
sensitive element is taken out through the elastic conductive member (7) and the conductive [(4).

Then, the electric signal #i may be derived from a lead wire (not shown) composed of a
reproduction needle of the conductive plate (4), which is 5 <far away from KJI. First, in the case
of the present embodiment, in the case where the holding body configured separately is provided
with a pair of conductive parts including an insulating member as in the example of the adhesive
shown in FIG. When it is connected to the plate (4) with solder or another conductive material
α9, an electric signal generated from the gas other than the holder to the electrode of the
pressure sensitive element can be taken out by k. Thus, according to the present invention, the
electrodes of the pressure-sensitive element are connected to the pair of conductive plates
formed by interposing the insulating member through the elastic conductive member, and the
electric signal generated by the pressure-sensitive element is generated to the required circuit.
Since the lead wire to be connected can be taken out from a position far away from the
regeneration needle, there is no risk of breaking the lead wire as in the conventional example
when cleaning the regeneration needle, and the lead wire As a load of the pressure sensitive
element, the influence on the frequency characteristic of the tII pressure sensitive element can be
reduced and it is practical.
