本考案は、レコードプレーヤ用のピツクアツプ
カートリツジに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pick-up cartridge for a record player.
従来のピツクアツプカートリツジの交換針の方
式は、ムービングマグネツト型（以下MM型とい
う）においては、角穴にパイプを差し込む方式、
ノブがシールドケースをくわえて保持する方式、
樹脂を利用したクリツクストツプ方式等がある。
またムービングコイル型（以下MC型という）に
おいてはスプリングを利用したクリツクストツプ
方式等がある。 The conventional way to replace needles in pick-up cartridges is by inserting a pipe into a square hole in the moving magnet type (hereinafter referred to as MM type).
A method in which the knob holds the shield case in its mouth,
There is a click stop method that uses resin.
In addition, the moving coil type (hereinafter referred to as MC type) includes a click-stop type that uses a spring.
しかし以上はいずれも針の支点を支える構造物
を確固に押える構成ではなく、全て嵌合によつて
いるために若干の遊びがあり、その遊びがガタを
招き、再生特性に悪影響を与えている。 However, none of the above configurations firmly press down on the structure that supports the fulcrum of the needle, and because they all rely on fitting, there is some play, and this play causes play and adversely affects the playback characteristics. .
本考案は斯る点に鑑みたもので、カートリツジ
本体をヘツドシエルに取り付けるに際しカバーを
用い、このカバーによつて同時に振動ユニツト部

ような問題点を解消したピツクアツプカートリツ
ジを提供せんとするものである。 The present invention was developed in view of these points, and uses a cover when attaching the cartridge body to the head shell, and uses this cover to securely attach the vibration unit to the main body, thereby solving the above-mentioned problems. The aim is to provide a pick-up cart storage.
以下、図を参照して本考案の一実施例を説明す

Ｃはカンチレバー４が挿通する孔７、及びヘツド
シエルＤへの取付孔８を有する。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an MC type pick-up cartridge, which consists of a cartridge body A, a vibration unit B, and a cover C. The cartridge body A has an output terminal 1, a yoke 2 serving as a vibration unit mounting portion, and a female connector 3, and the vibration unit B has a cantilever 4, a yoke 5, a male connector 6, and the like. The cover C has a hole 7 through which the cantilever 4 is inserted, and a hole 8 for attachment to the head shell D.

ことができる。 During assembly, the male connector 6 is fitted into the female connector 3 with the yoke 5 of the vibration unit B placed on the yoke 2 of the cartridge body A. As a result, the cartridge main body A and the vibration unit B are electrically coupled and mechanically temporarily coupled. Next, by placing both of them in the cover C and attaching the cover C to the head shell D by inserting a screw into the mounting hole 8, the mechanical connection between the cartridge body A and the vibration unit B is maintained by the cover C. By attaching it, it becomes solid. That is, the distance l 1 between the top of the yoke 5 of the temporarily connected vibration unit B and the bottom of the yoke 2 of the cartridge main body, and the distance l
If the relationship with the bottom depth l2 is such that l1 is slightly longer than l2 , then cover C can be
The vibration unit B can be held in a pressed state against the main body A depending on how tightly the screws are tightened when attaching the vibration unit B to the main body A.

C' is placed over the vibrating unit B', and the holder portion 10 of the vibration unit B' is pressed down by the tip 9 of the cover C'. This presser foot is
This is done by attaching C' to the head shell D by inserting a screw into its attachment hole 11. At this time, if the height l3 of the main body A' is slightly higher than the depth l4 of the cover C', the vibration unit B'
A' is strongly pressed by the cover C' and firmly fixed.
