Abstract
Description
【発明の詳細な説明】 本発明は、ＶＴＲのリール駆動機構の改良に関する。[Detailed description of the invention] The present invention relates to an improvement in a reel drive mechanism of a VTR.
従来のＶＴＲリール駆動機溝においては、巻戻し、早送

のリール駆動モータ、キャプスタンモータの駆動力を切
換えることによって行なっている。In a conventional VTR reel drive system, the reel is driven by switching the driving force of the reel drive motor and capstan motor on each side during rewinding, fast forwarding, and recording/reproduction.
即ち、第１図に示す如く、記録再生時においては、キャ

イドラー６を送り出しり−ル７に接触させて、リール駆
動モータ８の回転を送り出しリール７に伝えて磁気テー
プを送り出しリールに巻戻すものである。That is, as shown in FIG. 1, during recording and reproduction, the rotation of the capstan motor 1 is controlled by the belt 2. Pulley 3. The information is transmitted to the take-up reel 5 via the clutch idler 4, and the magnetic tape is wound onto the take-up reel 5. During rewinding and far winding, the clutch idler 4 and the take-up reel 5 are connected to each other as shown in FIG. At the same time, the rewind/long winding idler 6 is brought into contact with the feed reel 7, and the rotation of the reel drive motor 8 is transmitted to the feed reel 7 to rewind the magnetic tape onto the feed reel.
このように、従来のＶ Ｔ Ｒリール駆動ｉａ構にあっ

のは、その構造がＩＩ雑であると共に巻戻し・速交用ア
イドラーは、リール駆動モータに圧着されて摩擦力によ

った。In this way, the conventional VTR reel drive IA structure requires a clutch mechanism to switch the power source between recording and playback and rewinding/far winding. However, the rewind/speed transfer idler has disadvantages such as a relatively complicated structure and a large transmission loss because it is crimped onto the reel drive motor and driven by frictional force.
本発明は、以上の欠点を改良すべくなされたものであり
、記録再生１巻゛戻しの際、複雑なりラッチ機構を使う
ことなく、且つ、伝達ロスの少ないＶＴＲのリール駆動
４１ｋ 借を提供せんとするものである。The present invention has been made in order to improve the above-mentioned drawbacks, and provides a VTR reel drive 41K with less transmission loss without using a complicated latch mechanism when rewinding one reel of recording and playback. That is.
以下、図面に従って本発明の一実施例を説明する。An embodiment of the present invention will be described below with reference to the drawings.

一体に形成されている。On the reel winding side, there is a pulley 14 that transmits the rotation of a capstan motor (not shown). Lower gear 15. It consists of an upper gear 16 and a take-up reel stand 17, a lower gear 15 and an upper gear 1.
6 are coaxially rotatably supported, and the lower gear 15 is integrally formed with a pulley 14, and the upper gear 16 is integrally formed with a take-up reel stand 17.

The winding transmission gear 21 is rotatably and slidably supported on the shaft 18 so as to mesh with both or one of the gears 12, and the winding transmission gear 21 is connected to the lower gear 15 and the upper gear 16 on the reel winding side.
It is rotatably and slidably supported on a shaft 21 so as to mesh with both or one of the two.
次に、本発明に係るリール駆動機構の作用について説明
する。Next, the operation of the reel drive mechanism according to the present invention will be explained.
第３図は、記録再生時におけるリール駆動機構の状態を

下ギヤ１１と上ギヤ１２とに噛合し、また、巻取り伝達
ギヤ２１も、リール巻取す側の下ギヤ１５と上ギヤ１６

ヤ２１同志は、噛合していない。FIG. 3 shows the state of the reel drive mechanism during recording and reproduction, in which the supply transmission gear 19 meshes with the lower gear 11 and upper gear 12 on the reel supply side, and the winding transmission gear 21 also meshes with the reel supply side lower gear 11 and upper gear 12. , lower gear 15 and upper gear 16 on the reel winding side
However, the supply transmission gear 19 and the winding transmission gear 21 do not mesh with each other.
従って、図示しないキャプスタンモータの回転は、プー

ットの磁気テープを巻取りリールに巻取るものである。Therefore, the rotation of the capstan motor (not shown) is as follows: pulley 14 → lower gear 15 → winding transmission gear 21 → upper gear 16
The magnetic tape is transmitted to the take-up reel stand 17 via the winding reel, and the magnetic tape of a cassette (not shown) is wound onto a take-up reel.
尚、リール駆動モータｌＯの回転も、下ギヤ１１→供給

第４図は、遠巻時におけるリール駆動機構の状′ 態を
示すものであり、供給伝達ギヤ１９は、リール供給側の
下ギヤ１１のみと噛合し、巻取り伝達ギヤ２１はリール
巻取り側の上ギヤ１６に噛合すると共に、供給伝達ギヤ
１９と巻取り伝達ギヤ２１とは、互に噛合している。FIG. 4 shows the state of the reel drive mechanism during far winding, in which the supply transmission gear 19 meshes only with the lower gear 11 on the reel supply side, and the winding transmission gear 21 meshes with the lower gear 11 on the reel winding side. The supply transmission gear 19 and the winding transmission gear 21 are engaged with each other.
従って、リール駆動モータ１０の回転は、下ギヤ１１→

どの伝達が断たれていることから巻取りリール台１７に
伝わらず、遠巻取りが可能となる。Therefore, the rotation of the reel drive motor 10 is caused by the lower gear 11→
The rotation of the capstan motor is transmitted to the take-up reel stand 17 via the supply transmission gear 19 → take-up transmission gear 21 → upper gear 16, and the rotation of the capstan motor is transmitted to the lower gear 15 and upper gear 16 on the reel winding side.
Since which transmission is cut off, the winding is not transmitted to the take-up reel stand 17, and long-distance winding is possible.
第５図は、巻戻し時におけるリール駆動機構の状態を示

ギヤ１１と上ギヤ１２とに噛合しており、巻取り伝達ギ
ヤ２１は、リール巻取り側の下ギヤ１５にのみ噛合する

The supply transmission gear 19 is in mesh with the lower gear 11 and upper gear 12 on the reel supply side, and the winding transmission gear 21 is in mesh with the lower gear 11 and upper gear 12 on the reel supply side. , meshes only with the lower gear 15 on the reel winding side, and does not mesh with the supply transmission gear 19 and the winding transmission gear 21.
従って、リール駆動モータ１０の回転は、下ギヤ１１→
供給伝達ギヤ１９→上ギヤ１２を介して供給リール台１
３にのみ伝わり、巻取りリール台１７は、から回りの状

ある。Therefore, the rotation of the reel drive motor 10 is caused by the lower gear 11→
Supply transmission gear 19 → Supply reel stand 1 via upper gear 12
3, and the take-up reel stand 17 is in the empty state, making it possible to rewind the magnetic tape.
以上の説明から明らかなように、本発明によれば、複雑
