けることができる点である。[Detailed description of the invention] This invention relates to a structure for positioning a movable body in a pick-up carriage.The feature is that a pin is protruded near the rotating shaft to which the movable body is attached, When attaching the body to the rotating shaft, this pin is used to position the movable body in the rotational direction, and is removed after the attachment is completed, allowing for accurate and easy attachment without the need for a jig.
縦来、可動体を回転軸に取り付け際の回転方向
の位置決めは、治具を用いて行なつていたため、
組み立て工数が多くなり、また、組み立て時のバ
ラツキが発生しやすく精度を高めることがむずか
しかつた。 Traditionally, when attaching a movable body to a rotating shaft, positioning in the rotational direction was done using a jig.
This increases the number of assembly steps, and also tends to cause variations during assembly, making it difficult to improve accuracy.
この考案の目的は、治具を用いることなく、正
確かつ容易に取り付け時の位置決めを行なうこと
である。 The purpose of this invention is to accurately and easily perform positioning during installation without using a jig.
この考案の実施例について、図面を参照しなが
ら説明する。 An embodiment of this invention will be described with reference to the drawings.
第１図は、周知のリニアトラツキングアームの
縦断面図であり、トーンアーム１が、合成樹脂製
またはアルミダイキヤスト製のベース２に回動自
在に支持されている。 FIG. 1 is a longitudinal sectional view of a known linear tracking arm, in which a tone arm 1 is rotatably supported by a base 2 made of synthetic resin or aluminum die-casting.
ベース２の裏面には、トーンアーム１の回転軸
３の近傍にピン４が一体に形成され、また、トー
ンアーム１の回動検出装置のランプ５が設けられ
ている。 A pin 4 is integrally formed on the back surface of the base 2 near the rotating shaft 3 of the tone arm 1, and a lamp 5 of a rotation detection device for the tone arm 1 is also provided.
この回転軸３に、第２図に示されるようなシヤ
ツター６の軸孔７を嵌合し、第３図に示されるよ
うに、ピン挿入ガイド８にピン４をはさんで位置
決めし、ねじ９で固定する。 Fit the shaft hole 7 of the shutter 6 as shown in FIG. 2 into this rotary shaft 3, position the pin 4 by inserting it into the pin insertion guide 8, and screw 9 as shown in FIG. Fix it with.
そして、第４図および第５図に示されるよう
に、ピン４を根本から切断してシヤツター６を解
放し、最後にランプ５と対向する位置に光電検出
装置１０を設置する。 Then, as shown in FIGS. 4 and 5, the shutter 6 is released by cutting the pin 4 from its root, and finally the photoelectric detection device 10 is installed at a position facing the lamp 5.
また、第６図に示されるように、ピン４の根本
に細い部分を形成しておき、指で折り取るように
すれば、組立作業がより簡単になる。 Furthermore, as shown in FIG. 6, if a thin part is formed at the base of the pin 4 and can be broken off with one's fingers, the assembly work will be easier.
