本発明は、VTRのテープ走行系メカの調整作

はずれる問題がある。 Conventionally, when adjusting the tape running mechanism of a VTR, in order to align the bottom end of the tape with the cylinder lead, a 1st guide pin or a flange was provided on the guide roller to finely adjust the vertical position of the tape.
There was a structure in which the central axes of the guide pins and guide rollers were tilted so that the tape was not guided by those flanges when the tape was running. However, the disadvantages of these structures are that method (1) requires a lot of time to adjust the tape height and the recording section at the top of the tape is damaged quickly. During operation, there is a problem that the tape easily comes off the lead on the cylinder entry side, and also that it comes off the lead on the cylinder exit side when the tape is running at high speed, such as during picture search.

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 new tape running mechanism. That is, it is an object of the present invention to provide a tape running mechanism that has functions such as facilitating the adjustment method, stabilizing tape running, preventing damage to the end of the tape where audio is recorded, and reducing back tension.

したものである。 In order to achieve the above object, the present invention makes the flange intervals of the guide pins and guide rollers in the tape running mechanism longer than the tape width, and tilts the axis in the front, back, left and right directions. By adjusting the lower end of the tape so that it contacts the lower flange and the cylinder lead without making contact between the upper flange and the upper end of the tape, the lower end of the tape can be deflected against the cylinder lead with a constant pressure.

せることができる。 FIG. 1 shows an embodiment of the present invention. On a chassis 1 having a reference surface for a tape running system, an entrance guide roller base 2 is assembled so as to be slidable back and forth by tilting θ to the right and α to the front. On the entrance guide roller base 2, the entrance inclined pin 4, the entrance guide roller lower flange 6, the entrance guide roller 7, and the entrance guide roller upper flange 8 are assembled, respectively. The entry catcher 3 is a stopper for the entry guide roller base 2 and is fixed at a predetermined position on the chassis 1. The exit side has almost the same structure as the entrance side, and includes an exit side inclined pin 10, an exit guide roller upper flange 11, an exit guide roller 12, an exit guide roller lower flange 13, an exit catcher 14, and an exit guide. It is composed of a roller base 15. In addition, 9 indicates an upper cylinder equipped with a rotating head, and 16 indicates a cylinder lead for regulating the position of the tape 5. In the above tape running mechanism, when magnetic recording and reproducing are performed with the tape 5 mounted on a predetermined path, the tape 5 is run with only the lower flange 6 of the entrance guide roller in contact with the lower end of the tape. In this way, the tape 5 can be stably aligned with the cylinder lead 16.

チなど高速走行でも安定となる。 FIG. 2 shows another embodiment of the present invention. The difference from the embodiment shown in FIG. 1 is that the tape 5 is run with the lower end of the tape 5 brought into contact with the lower flange 13 of the output guide roller. That is, the lower flanges 13 and 6 on the inlet and outlet sides are brought into contact with the lower end of the tape 5 to run the tape for recording/reproduction. In this way, the tape 5 can be more stably aligned with the cylinder lead 16, and the tape 5 can be stabilized even during high-speed running such as picture search.

ジを使用する。 Stress is applied to the part where the lower flange 6 of the entrance guide roller and the lower end of the tape 5 contact, causing the lower end of the tape to buckle. To prevent this, the tape 5 is set at an angle equal to the incident angle θ 1 of the tape 5 with respect to the generatrix of the roller 7.
It is assumed that the lower flange 6 is tapered. The upper flange 8 is also tapered at an angle equal to the incident angle θ 2 when the tape 5 comes into contact with the tape 5 during running. Similarly, on the exit side, a flange with tapers of θ 1 and θ' 2 equal to the incident angle of the tape is used.
このように構成することによつて、本発明は下
記のような効果が得られる。 With this configuration, the present invention can achieve the following effects.
(1) 調整作業時間の削減が可能。(1) Adjustment work time can be reduced.
ガイドローラの上フランジを記録再生のテープ
走行中に使用しない構造であるため、従来最も作
業時間を費していたテープ上下端部のカール現象
対策のための微調整作業をする必要がなくなる。 Since the upper flange of the guide roller is not used while the tape is running during recording and playback, there is no need to perform fine adjustment work to counter the curling phenomenon at the upper and lower ends of the tape, which conventionally took the most time.
(2) テープ傷みを少くすることが可能。(2) Possible to reduce tape damage.
ガイドローラの上フランジを記録再生のテープ
走行中に使用しない構造であるため、テープの音
声トラツク部の傷みを少くできる。特に薄いテー
プに有効である。 Since the upper flange of the guide roller is not used during tape running during recording and playback, damage to the audio track portion of the tape can be reduced. Particularly effective for thin tapes.
(3) テープのバツクテンシヨンを小さくすること
が可能。(3) Tape back tension can be reduced.
傾斜させた入側ガイドローラベースを使用し、
入側ガイドローラフランジとテープを接触させて
走行するため、入側で安定なテープ走行性が得ら
れる結果、バツクテンシヨンを小さくすることが
できる。 Using a slanted entry guide roller base,
Since the tape runs in contact with the guide roller flange on the entry side, stable tape running performance is obtained on the entry side, and as a result, back tension can be reduced.
(4) テープガイド機構の削減が可能。(4) Tape guide mechanism can be reduced.

機構があつたが、本発明ではテープ走行の安定性
が向上した結果、それらが不要となる。 In addition to conventional guide rollers and inclined pins on the entrance and exit side,
Although there was a mechanism for adjusting the vertical position of the tape using a tape guide, the present invention eliminates the need for such a mechanism because the stability of tape running is improved.
