高速で走行させると。The conventional tape guide section 10 is molded from the same resin as the main body case 1, for example, a thermoplastic resin such as ABS41 resin or polyacetal. Therefore, if a back coat of carbon or the like is applied to the back of the tape 3, especially if it is run at high speed.

ー特性の低下などテープ特性に悪影響を及ぼしていた。The sliding contact portion of the tape 3 with the back coat in the tape guide portion 10 was easily worn, and the tape running characteristics were deteriorated. Furthermore, shavings are generated from the sliding contact portions of the tape guide portion 10, which adversely affects tape characteristics such as increased dropouts and decreased tape jitter characteristics.
また、熱可塑性樹脂製のテープガイド部１０は。Further, the tape guide section 10 is made of thermoplastic resin.

ジを得るにある。SUMMARY OF THE INVENTION It is an object of the present invention to provide a tape cartridge that eliminates the above-mentioned conventional drawbacks, improves the wear resistance of the tape guide portion, prevents the generation of shavings, and improves and stabilizes dimensional accuracy.
上記の目的を達成するために９本発明のテープカートリ
ッジでは、テープガイド部１０を熱硬化性樹脂で成形し
たものである。In order to achieve the above object, in the tape cartridge of the present invention, the tape guide portion 10 is molded from a thermosetting resin.
熱硬化性樹脂としては、フェノール樹脂が他の熱硬化性
樹脂、たとえばエポキシ樹脂などに比べて射出成形性に
優れる点で好ましい、また、フェノール樹脂単独よりも
ガラス繊維の充填したものを用いれば、引っ張り１曲げ
強度、熱変形温度が向上し、成形収縮が小さくなってよ
り好ましい。As the thermosetting resin, phenolic resin is preferred because it has superior injection moldability compared to other thermosetting resins, such as epoxy resins, and if a phenolic resin filled with glass fiber is used rather than a phenolic resin alone, It is more preferable because the tensile 1 bending strength and heat deformation temperature are improved and the molding shrinkage is reduced.
更に、ガラス繊維の充填が多すぎると成形性が悪くなり
、テープ３を傷める一方、少なすぎると耐摩耗性が低下
するため、２０〜３０％のガラス繊維入りフェノール樹
脂が用いて好適である。Furthermore, if the amount of glass fibers is too large, the moldability will deteriorate and the tape 3 will be damaged, while if the amount of glass fibers is too small, the abrasion resistance will decrease, so it is preferable to use a phenolic resin containing 20 to 30% glass fibers.
テープガイド部１０は本体ケース１とは別体に成形して
もよいし、一体に成形してもよい。The tape guide portion 10 may be molded separately from the main body case 1, or may be molded integrally with the main body case 1.
熱硬化性樹脂製のテープガイド部１０は硬度が高（なり
、バックコートされたテープ３を高速走行させる場合も
、これとの摺接で摩耗することが非常に少なくなり、削
り粉が発生することも無い。The tape guide part 10 made of thermosetting resin has high hardness (so that even when the back-coated tape 3 is run at high speed, there is very little wear due to sliding contact with it, and shavings are generated. No problem.
