【発明の詳細な説明】
本発明はテープカセットに関し、テープ走行が円滑に行
なわれるようにしたものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape cassette that allows smooth tape running.
従来、テープカセット内にはテープをカセット前面に形
成された開口部に沿って走行させるために回転可能なテ
ープガイドローラが備えられている。しかしながら、こ

るものである。Conventionally, a tape cassette is provided with a rotatable tape guide roller for running the tape along an opening formed in the front surface of the cassette. However, if the dimensional accuracy of this guide roller is not good, it will rotate with a 1 degree inclination, causing center runout, which will actually worsen the running of the tape.
本発明はこのような従来の欠点を解消したものであり、
以下その一実施例について図面を用いて説明する。The present invention eliminates these conventional drawbacks,
An example of this will be described below with reference to the drawings.

働きをもっている。8.9, 10, 11.12 are openings provided on the front side of the half 1, through which a head, a pinch roller, etc. are inserted and come into contact with the tape. 13.14 is the tape winding layer part, 1
Reference numeral 5 denotes a tape between the winding layer parts 13 and 14, which is guided by the guide pins 2 and 3 and tape guides 4 and 6 to open the openings 8 to 14.
12. Reference numeral 16 denotes a slippery sheet interposed between the tape winding layer part 13.14 and the node 71, which smoothes the rotation of the tape winding layer part 13.14 and smoothes the end surface of the tape winding surface. It has the function of aligning the

てテーパー状に形成されておシ、かつ周面下端部には突
片４ｂが形成されている。Here, to explain in detail the tape guide bodies 4 and 5, the tape guide bodies 4 and 5 are made of fluororesin or the like and have a coefficient of friction with the tape 16 of 0.15 or less, and one of them is particularly shown in FIG. As shown in FIG. 3, the hole 4a has a diameter smaller at the center than at the upper and lower ends, and is tapered from the center in the vertical direction, and has a protruding piece at the lower end of the circumference. 4b is formed.

しである。On the other hand, the protrusion 4b is inserted between the half 1 and the stop bar 1 for preventing the rotation of the tape guide 4.
7b is provided, whereby the tape guide body 4 guides the tape in a state where rotation is restrained. The tape guide 5 side has a similar structure, with the protruding piece being 6b and the stoppers being 18a and 1sb.

行が行なわれ、ヘッドにより記録、再生が行なわれるが
、この場合ヘッド部を走行するテープはそのヘッド等と
ともに挿入されたテープガイドにより高さ規制が行なわ
れる。With the above configuration, the head, pinch roller, etc. are inserted through the openings 8 to 12, the tape is run by the capstan and the pinch roller, and recording and playback are performed by the head, as in a general tape recorder. However, in this case, the height of the tape running on the head section is regulated by a tape guide inserted together with the head and the like.
そして、テープ案内体４，６ではテープ１６がその案内
体４，５０周面に対して傾斜した状態で走行されて来る
と、該案内体４，６はその孔４ａ。In the tape guides 4, 6, when the tape 16 is run in an inclined state with respect to the circumferential surface of the guides 4, 6, the guides 4, 6 close their holes 4a.
６ａの中央部の小径部を支点にしてテープの傾斜に倣っ
て傾き、このためテープ１５の部分的なたるみが解消さ
れ、スムーズなテープ走行が行なわれるものである。The small diameter portion at the center of the tape 6a is used as a fulcrum and the tape 15 is tilted to follow the tape's inclination, thereby eliminating any partial slack in the tape 15 and allowing smooth tape running.
なお、このテープ案内体４，５のテープ走行面に沿う変
位は例えそのテープ案内体４，６の下面が平面によって
受けられていてもこのテープ案内体４，６は非常に軽い
ためテープ１６の走行による偏位張力によって上方に多
少持上げられてテープ走行面に周面が倣うことになる。Incidentally, the displacement of the tape guides 4, 5 along the tape running surface is caused by the displacement of the tape 16 even if the lower surfaces of the tape guides 4, 6 are supported by a flat surface because the tape guides 4, 6 are very light. Due to the deflection tension caused by running, the tape is slightly lifted upward and the circumferential surface follows the tape running surface.

係数が０．１５以下に形成することによって回動するガ
イドローラと同一程度の負荷とすることができ、テープ
走行負荷の増大を解消することができる。Therefore, since the tape guides 4 and 5 are prevented from rotating, there is no possibility of unstable tape running due to the outer periphery wobbling unlike conventional rotating ones. Since the tape is automatically tilted to follow the running surface of the tape that is about to be guided, the tape runs smoothly. In addition, by forming the tape guide surfaces of the tape guides 4 and 5 to have a coefficient of friction with the tape of 0.15 or less, the load can be made to be about the same as that of a rotating guide roller, and an increase in tape running load can be reduced. It can be resolved.
なお、テープ案内体４，６の傾斜が犬きく、テープ走行
位置が大きくずれるような場合はその上下端部に鍔を設
けるとか、テープ案内体の前後にテープ走行高さ規制部
を設けてやればよい。If the inclination of the tape guides 4 and 6 is too steep and the tape running position deviates significantly, it is recommended to provide flanges at the upper and lower ends of the tape guides, or to install tape running height regulating sections at the front and rear of the tape guides. Bye.
本発明は以上のように簡単な構成でテープ走行を安定さ
せることができるとともに各部品に要求される精度も緩
和することができるものである。As described above, the present invention is capable of stabilizing tape running with a simple configuration, and can also reduce the accuracy required for each component.
