関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a guide roller for a VTR that prevents noise generation and uneven rotation due to insertion of foreign matter into the gap between the guide roller and the flange during running of a magnetic tape for a VTR. Regarding assembled products.

ットケース側に傾けている。As shown in Figure 2, a conventional guide roller assembly for a VTR consists of a solid plastic guide roller inserted into a stainless steel shaft, and a metal (mainly stainless steel) guide roller to hold the guide roller. The upper and lower flanges are press-fitted and fixed. At this time, the one-guide roller assembly has its upper side tilted toward the cassette case in which the tape is stored in order to press the upper end of the tape with the upper flange and stabilize tape running.

At this time, if a small amount of foreign matter such as magnetic powder adheres to the gap 5 between the guide roller and the upper flange, although this is rare, the rotation will become unsmooth, resulting in abnormal periodicity or uneven rotation. There was.

ある。SUMMARY OF THE INVENTION An object of the present invention is to provide a guide roller assembly for a VTR that eliminates the drawbacks of the prior art described above and eliminates the influence of foreign matter that has entered between the first guide roller and the upper flange.
本発明の特徴は、ＶＴＲ用ガイドローラ組立品における
ガイドローラの上側フランジと接する面をテーパにして
異物挿入による影響２なくしたことにある。A feature of the present invention is that the surface in contact with the upper flange of the guide roller in a guide roller assembly for a VTR is tapered to eliminate the influence 2 caused by insertion of foreign matter.
以下に、本発明の一実施例について説明する。 An embodiment of the present invention will be described below.

転ムラの発生はなくなる。Like the shape of the solid guide roller 1' shown in FIG.
A taper is provided on the surface 1'α on the upper flange 3 side. Due to this tapered part, most of the minute foreign matter such as magnetic powder is discharged to the outside, and even if it remains and adheres, it is so small that the guide roller 1' can be smoothly moved without any foreign matter coming into contact with the upper flange. Since it can rotate, there will be no periodic abnormal noise or uneven rotation.

効果がある。The present invention eliminates the influence of foreign matter that has gotten into the gap between the upper flange and the guide roller, so periodic abnormalities in the sliding between the upper flange and the guide roller due to foreign matter adhesion, which previously occurred in rare cases, can be eliminated. This has the effect of eliminating sound.
