従来のテー プガイ ドロ ー ラ は、 例えば第 1 図に示すよ う に、 ス テ ン レ ス鐧ゃ真鍮等か ら成る棒材をス リ ーブ状 に切削 して形成 した外筒 1 内へ、 ポ リ アセ夕 一ル等の合 成樹脂か ら成る棒材を切削 して形成 した内筒 2 を圧入す る こ と に よ り 製作さ れていた。  As shown in Fig. 1, for example, a conventional tape guide roller is placed in an outer cylinder 1 formed by cutting a bar made of stainless steel or brass into a sleeve shape. It was manufactured by press-fitting an inner cylinder 2 formed by cutting a rod made of synthetic resin such as polyurethane resin.
又、 従来のテープガイ ドロ 一 ラ と して第 2 図に示すよ う な構成の も の も あ るが、 こ れは、 ステ ン レ ス鋼等か ら 成る棒材をス リ 一ブ状に切削 した後さ ら に内側に段部 1 c を形成 した外筒 1 を、 第 3 図（a)に示すよ う に金型 3 に 挿入し、 次に金型 3 を閉 じて第 3 図 (b)に示すよ う に溶融 したポ リ アセ 夕 一ルゃポ リ イ ミ ド等の合成樹脂を流 し込 んで内筒 2 を成形する こ と に よ り 、 製作されていた。  FIG. 2 shows a conventional tape guide roller having a configuration as shown in FIG. 2. In this case, a rod made of stainless steel or the like is formed into a sleeve. After cutting, the outer cylinder 1 with the step 1c formed inside is inserted into the mold 3 as shown in Fig. 3 (a), and the mold 3 is closed. As shown in (b), the inner cylinder 2 was manufactured by pouring a synthetic resin such as a molten polycarbonate resin into the inner cylinder 2.
と こ ろで、 第 1 図に示すよ う なテープガイ ドロ ー ラ の 場合、 外筒 1 内へ内筒 2 を圧入する と き圧入力 にば らつ きが発生 し易 く 、 又、 外筒 1 と内筒 2 の両端部が不揃い になる こ とが多かっ た。 又、 外筒 1 内へ内茼 2 を圧入す る と き圧入冶具に よ り 外筒 1 を傷つけて しま う こ とがあ つ た。 In the case of a tape guide roller as shown in Fig. 1, when the inner cylinder 2 is press-fitted into the outer cylinder 1, the pressure input tends to fluctuate. Both ends of 1 and inner cylinder 2 are not aligned Was often the case. Also, when the inner cylinder 2 was pressed into the outer cylinder 1, the outer cylinder 1 could be damaged by the press-fitting jig.
又、 第 2 図に示すよ う なテープガイ ドロ ー ラ の場合は、 外筒 1 の内径が小さいため段部 1 c を切削に よ り 形成す る のは難し く 、 こ のため外筒の製作コ ス トが上昇する と い う 問題があ った。 又、 こ の構造のテ一プガイ ドロ ー ラ は、 使用中に外筒 1 と内筒 2 の結合が外れて、 外筒 1 の みが回転し、 内筒 2 の外周面を傷つけ、 その結果外筒 1 が偏芯 して回転むらを起こ し、 使用上極めて不都合な状 態になっ て し ま う こ とがあ っ た。  In the case of a tape guide roller as shown in Fig. 2, it is difficult to form the step 1c by cutting because the inner diameter of the outer cylinder 1 is small. There was a problem that costs would rise. In addition, in the tape guide roller having this structure, the outer cylinder 1 and the inner cylinder 2 are disengaged from each other during use, and only the outer cylinder 1 rotates, thereby damaging the outer peripheral surface of the inner cylinder 2. The outer cylinder 1 was eccentric, causing rotation unevenness, and was in an extremely inconvenient state in use.
一般にステン レス鋼は高価な材料であ る ため、 ステ ン レス鋼の棒材をス リ ーブ状に切削 して使用する場合は材 料費が極めて高 く なつて しま う とい う 問題はあるが、 ス テ ン レス鐧は耐敏性， 耐摩耗性に優れ、 而も テープ との 摩擦抵抗が小さいため、 テープガイ ドロ ー ラ の外筒と し て望ま しい とい う 要求があ る。  Since stainless steel is generally an expensive material, there is a problem in that if a stainless steel bar is cut into a sleeve and used, the material cost will be extremely high. However, stainless steel has excellent sensitivity and abrasion resistance, and has low frictional resistance with the tape, so there is a demand that it be desirable as the outer tube of the tape guide roller.

First, a 0.2 mm thick sheet of stainless steel is cut into a suitable size by pressing, and a notch lb is formed in the center. Next, the thin plate is drawn and formed into a cylindrical shape so that the notch portion 1b becomes one end of the cylinder, and the end wall provided with the notch portion 1b is formed. The bent portion 1a is formed by bending the inner side of the wire. The outer cylinder 1 thus obtained is inserted into a mold as shown in FIG. 3, and the melted synthetic resin is poured into the outer cylinder 1. The inner cylinder 2 is formed so as to enclose the bent portion 1a. Thus, the inner and outer cylinders can be firmly connected.

This embodiment is different from the first embodiment in that a bent portion 1c is formed at the other end of the outer cylinder 1. The bent portion 1c is not limited to the shape shown in the figure, and may have the same shape as the bent portion 1a shown in FIG. Further, the bent portion 1c may not have the notch extending in the radial direction.
以上各実施例において、 屈曲部 1 a と して種々 の形状 が示さ れ、 又、 半径方向に延びた切 り 欠き部 1 b も互い に異な る数が示さ れたが、 こ れ ら は適宜変更する こ とが 可能であ り 、 特に上記切 り 欠き部は少な く と も一つあれ ばよ く 、 その数は内筒 2 を形成する合成樹脂の種類等を 考慮 して適宜選定される。 又、 外筒を形成する ステ ン レ ス鋼の厚さ も、 0. 2 mmに限定される ものではな く 、 その 材料も非磁性金属であればよ く 、 テープガイ ドロ ー ラ力 使用 されるべき機器に合わせて適宜選定され得る。 In each of the embodiments described above, various shapes are shown as the bent portions 1a, and the numbers of the notched portions 1b extending in the radial direction are also different from each other. It is possible to change it, and in particular, there should be at least one notch, and the number depends on the type of synthetic resin forming the inner cylinder 2 and the like. It will be appropriately selected in consideration of the situation. Also, the thickness of the stainless steel forming the outer cylinder is not limited to 0.2 mm.
