本考案はレコードプレーヤのベルトドライブ用のターン
テーブル装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a turntable device for a belt drive of a record player.
従来ベルトドライブのレコードプレーヤのターンチーフ
ル装置には、ターンテーブル部とプーリ部と自動演奏装
置の操作制御をするギア及び爪部がダイカストで一体と
なったもの、又ターンテーブルとプーリ部がダイカスト
でギヤ部が樹脂成形された別品のもの、ターンテーブル
部とプーリ部とギヤ部が別々に作られたもの等があるが
、前記第一、第二のターンテーブル装置は高師であるこ
と又第三のものは組立て時にプーリ部ギヤ部の回転精度
がでにくい等の欠点があった。Conventional turntable devices for belt-drive record players include those in which the turntable section, pulley section, gears and pawls that control the operation of the automatic performance device are integrated by die-casting, and those in which the turntable and pulley sections are made of die-casting. There are models in which the gear part is molded separately from resin, and models in which the turntable part, pulley part, and gear part are made separately, but the first and second turntable devices are of high quality. The third type had drawbacks such as difficulty in achieving rotational accuracy of the pulley gear part during assembly.
本考案の目的は、上記従来技術の欠点を無くし、安価で
かつ性能の良好なレコードプレーヤのターンテーブル装
置を提供するにある。SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the prior art described above and to provide a turntable device for a record player that is inexpensive and has good performance.
本考案は目的を達成するために、ターンテーブルのレコ
ード載置部と、プーリ部、ギヤ部を分離し、プーリ部と
ギヤ部を一体に樹脂成形したものである。In order to achieve the object of the present invention, the record mounting section, pulley section, and gear section of the turntable are separated, and the pulley section and the gear section are integrally molded with resin.
第１図は本考案の一実施例を示す。FIG. 1 shows an embodiment of the present invention.
第１図において、１はシャフト、２はブツシュ、３は樹
脂成形されたプーリで、ギア部３ａ、ベルトを張架させ
るプーリ部３ｂ 、同一円周上に複数個のボス部３ｃ、
爪部３ｄを有し、インサートされたブツシュ２にシャフ
ト１が圧入され、シャフト１の頂部にセンタースピンド
ル４が圧入されている。In FIG. 1, 1 is a shaft, 2 is a bush, 3 is a resin-molded pulley, which includes a gear portion 3a, a pulley portion 3b for tensioning the belt, a plurality of boss portions 3c on the same circumference,
The shaft 1 is press-fitted into the inserted bush 2, which has a claw portion 3d, and the center spindle 4 is press-fitted into the top of the shaft 1.
ギア部３ａ、爪部３ｄは自動演奏装置の操作制御部であ
り、爪部３ｄは、第１図では図示されていないが、通常
広く採用されている自動復帰装置のクラッチとにより、
レコード終端検出及び起動動作をしており、ギア部３ａ
は自動復帰装置に駆動力を与える動作をする。The gear portion 3a and the pawl portion 3d are the operation control portion of the automatic performance device, and the pawl portion 3d is not shown in FIG.
It detects the end of the record and starts the operation, and the gear part 3a
acts to provide driving force to the automatic return device.
５はアルミ絞り加工されたターンテーブルでボス部３ｃ
と相対する位置に複数の穴５ａを有し、ネジ６でプーリ
３と固定されてターンテーブル装置を構成する。5 is an aluminum drawn turntable with boss part 3c
It has a plurality of holes 5a at positions facing the pulley 3, and is fixed to the pulley 3 with screws 6 to form a turntable device.
ネジ６０代りに第２図の如くモールドボス部の代りにピ
ン部３ｆを形成し、ターンテーブル５を装着後、溶着し
ても良い。Instead of the screw 60, a pin portion 3f may be formed instead of the mold boss portion as shown in FIG. 2, and after the turntable 5 is attached, it may be welded.
このように本考案は、ギヤ部とプーリ部を一体に樹脂成
形したので、ターンテーブルはアルミ板から絞り加工し
たものを使用でき、このためアルミダイカストターンテ
ーブルに比較し安価となる。In this way, in the present invention, the gear part and the pulley part are integrally molded with resin, so the turntable can be drawn from an aluminum plate, and is therefore cheaper than an aluminum die-cast turntable.
筐たターンテーブル全体の重量が軽減でき軸受の負荷を
少くすることができ、又起動特性も良いし、ダイカスト
ターンテーブルと同程度の回転ムラの性能が得られる。The weight of the entire turntable in the housing can be reduced, the load on the bearings can be reduced, and the starting characteristics are also good, and performance with rotational unevenness comparable to that of a die-cast turntable can be obtained.
さらにターンテーブルの外径が異なる仕様に対しても、
他の部品は共用でき、さらにまた製作工程中、ターンテ
ーブル外観部が損傷しても、交換が容易かつ安師である
等の利点がありその効果は大きいものである。Furthermore, for specifications with different turntable outer diameters,
Other parts can be shared, and even if the external part of the turntable is damaged during the manufacturing process, it is easy to replace and can be easily replaced, which is a great advantage.
