本考案は、オーディオ、ビデオ機器やコンピュター等において、磁気テープを 案内するためのテープガイドのうちの、金属シャフトに取り付けられている回転 ローラに関する。 The present invention relates to a rotating roller attached to a metal shaft of a tape guide for guiding a magnetic tape in audio equipment, video equipment, computers and the like.
【０００２】[0002]
従来のテープガイドローラは、例えば図７に示すように、ステンレス鋼や真鍮 等の棒材をスリーブ状に切り出した外周部１に、ポリアセタール等の部材を切削 加工して作られた内周部２を前記外周部１の内側に圧入固定するという方法で作 っていた。 As shown in FIG. 7, for example, a conventional tape guide roller has an inner peripheral portion 2 formed by cutting a member such as polyacetal into an outer peripheral portion 1 obtained by cutting a rod material such as stainless steel or brass into a sleeve shape. Was fixed by press-fitting inside the outer peripheral portion 1.
【０００３】 また、図８に示すテープガイドローラは、ステンレス鋼等の棒材をスリーブ状 に切り出し、さらに内側に段部１ｃを切削加工した外周部１を、図９に示すよう に、金型３に挿入し、次に溶融したポリアセタールやポリイミド等の合成樹脂を 流しこんで内周部２を成形することで、外周部１と内周部２を一体にするという 方法で作っていた。Further, the tape guide roller shown in FIG. 8 is obtained by cutting a rod material such as stainless steel into a sleeve shape and further cutting a step portion 1 c inside to form an outer peripheral portion 1 as shown in FIG. The outer peripheral portion 1 and the inner peripheral portion 2 were made integral by pouring the melted synthetic resin such as polyacetal or polyimide into the inner peripheral portion 2.
【０００４】[0004]
図７に示すテープガイドローラの場合、外周部１に内周部２を圧入するとき圧 入力にバラツキが発生しやすく、長手方向両端部が外周部１と内周部２で不揃い になることが多かった。 また、上記圧入時に誤って圧入治具でテープガイドローラの外周部１を傷つけ てしまうことがあった。 In the case of the tape guide roller shown in FIG. 7, when the inner peripheral portion 2 is press-fitted into the outer peripheral portion 1, variations in the pressure input are likely to occur, and both ends in the longitudinal direction may become uneven between the outer peripheral portion 1 and the inner peripheral portion 2. There were many. Also, the outer peripheral portion 1 of the tape guide roller may be erroneously damaged by the press-fitting jig during the press-fitting.
【０００５】 図８の場合だと、外周部１の内側の内径が小さいので段部１ｃを切削加工する のが難しく、また、テープガイドローラの使用中、外周部１と内周部２の結合が ずれて、外周部１のみが回転してしまい内周部２の外側を傷つけ、外周部１が偏 芯して回転むらを起こし、使用上大変不都合な状態になってしまうことがあった 。 また、ステンレス鋼は高価な材料なので、ステンレス鋼の棒材をスリーブ状に 加工して使用することは、材料費が極めて高くなってしまう、という問題があっ た。 しかし、テープガイドローラの外周部の材質をステンレス鋼にすると、耐蝕耐 磨耗性がよく、しかもテープとの摩擦抵抗の少ないテープガイドローラを製造す ることができるので、テープガイドローラの外周部の材質としてはステンレス鋼 を用いることが望ましいという要求があった。In the case of FIG. 8, since the inner diameter of the outer peripheral portion 1 is small, it is difficult to cut the step portion 1c, and the outer peripheral portion 1 and the inner peripheral portion 2 are joined during the use of the tape guide roller. However, the outer peripheral portion 1 is rotated, and the outer peripheral portion 1 is damaged, and the outer peripheral portion 1 is eccentric to cause uneven rotation, which may be very inconvenient for use. Further, since stainless steel is an expensive material, there is a problem in that the material cost becomes extremely high when a stainless steel bar is processed into a sleeve and used. However, if the material of the outer peripheral portion of the tape guide roller is made of stainless steel, it is possible to manufacture a tape guide roller that has good corrosion resistance and abrasion resistance and low friction resistance with the tape. There was a demand that it was desirable to use stainless steel as the material.
【０００６】 本考案は、上述の如き高価なステンレス鋼の部分をできるだけ少なくして、さ らに外周部と内周部が別々に回転することを防ぐための機構を設けたテープガイ ドローラを提供することを目的とする。The present invention provides a tape guide roller provided with a mechanism for reducing the above-mentioned expensive stainless steel portion as much as possible and preventing the outer peripheral portion and the inner peripheral portion from rotating separately. The purpose is to

本考案は、外周部をステンレス鋼などの非磁性金属の薄板を絞り加工によって 円筒形に作ると共に、一方の端部に内周部に対する抜け防止と回転防止のための 、内側に曲げられた屈曲部を設け、前記外周部を金型に挿入して、前記屈曲部を 合成樹脂で包み込むようにしてインサート成形することで作ることができるテー プガイドローラによって、上記課題を解決する。 According to the present invention, a thin plate made of non-magnetic metal such as stainless steel is formed into a cylindrical shape at the outer periphery, and one end is bent inward to prevent the inner periphery from slipping out and preventing rotation. The above problem is solved by a tape guide roller that can be formed by providing a portion, inserting the outer peripheral portion into a mold, and wrapping the bent portion with synthetic resin and performing insert molding.
【０００８】[0008]
上記構成により、外周部をステンレス鋼などの薄板で絞り加工により作ること ができるので、材料費の安いテープガイドローラが製造できる。 また、内側に曲げられた屈曲部を内周部内に成形によって埋め込んでしまうこ とで、外周部に対する内周部の抜け止めと回り止めの効果を得る。 With the above configuration, the outer peripheral portion can be formed by drawing with a thin plate such as stainless steel, so that a tape guide roller with low material cost can be manufactured. Further, by embedding the bent portion that is bent inward in the inner peripheral portion by molding, the effect of preventing the inner peripheral portion from slipping off from the outer peripheral portion and preventing rotation can be obtained.

以下、図面に従って、本考案の実施の一例を説明する。 図１は、本考案によるテープガイドローラの一例を示す断面図である。 １はステンレス鋼の厚さがたとえば０．２ｍｍの薄板で作られた外周部で、一 方の端部を内側へ曲げて屈曲部１ａを形成している、２は合成樹脂で作られた内 周部である。 図２は、上記テープガイドローラの外周部１のみの側面図で、屈曲部１ａの４ 等分位置に切り欠き部１ｂが設けられている。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing an example of a tape guide roller according to the present invention. Reference numeral 1 is an outer peripheral portion made of a thin plate of stainless steel having a thickness of 0.2 mm, for example, and one end is bent inward to form a bent portion 1a. 2 is an inner portion made of synthetic resin. It is the perimeter. FIG. 2 is a side view of only the outer peripheral portion 1 of the tape guide roller, in which a cutout portion 1b is provided at four equal positions of the bent portion 1a.
【００１０】 次に、上記テープガイドローラの製造工程を説明する。 まず、ステンレス鋼の０．２ｍｍの薄板を適当な大きさに切断し、一方の長手 方向端部となる部分に切り欠き部１ｂを等間隔に４ヶ所設ける。 そして、絞り加工で上記薄板を、切り欠き部１ｂが一方の端部の側へ行くよう な円筒形に加工すると同時に、切り欠き部１ｂを設けた側の薄板の端部を内側へ 曲げて屈曲部１ａを設けることで、外周部１を作る。Next, a manufacturing process of the tape guide roller will be described. First, a 0.2 mm thin plate of stainless steel is cut into an appropriate size, and four notch portions 1b are provided at equal intervals in one end portion in the longitudinal direction. Then, by drawing, the thin plate is processed into a cylindrical shape such that the cutout portion 1b goes to one end side, and at the same time, the end portion of the thin plate on which the cutout portion 1b is provided is bent inward and bent. The outer peripheral portion 1 is made by providing the portion 1a.
【００１１】 出来上がった外周部１を金型へ挿入し、外周部１の円筒形の内側に溶融した合 成樹脂を流しこんで、屈曲部１ａを包み込むようにして内周部２をインサート成 形することで、図１に示すようなテープガイドローラを作る。The finished outer peripheral portion 1 is inserted into a mold, the molten synthetic resin is poured into the cylindrical shape of the outer peripheral portion 1, and the inner peripheral portion 2 is insert-molded so as to wrap around the bent portion 1a. By doing so, a tape guide roller as shown in FIG. 1 is produced.
【００１２】 屈曲部１ａは、図１に示す形に限定するものではなく、例えば図３、図４のよ うな形状でもよい。切り欠き部１ｂの数も４ヶ所に限定するものではなく、例え ば図５、図６に示すように２ヶ所、３ヶ所など少なくとも１ヶ所あればよく、内 周部を成形する合成樹脂の種類等を考慮して、適宜に設定すればよい。 また、ステンレス鋼の厚さも、０．２ｍｍに限定するものではなく、真鍮等他 の非磁性材料であってもよく、テープガイドローラを使用する機器等に合わせて 、適宜に設定されるものである。The bent portion 1a is not limited to the shape shown in FIG. 1, and may have a shape as shown in FIGS. 3 and 4, for example. The number of cutouts 1b is not limited to four, and for example, as shown in FIGS. 5 and 6, at least one such as two and three may be used, and the type of synthetic resin that molds the inner circumference It may be set appropriately in consideration of the above. Further, the thickness of the stainless steel is not limited to 0.2 mm, but may be other non-magnetic material such as brass, and may be set appropriately according to the device using the tape guide roller. is there.

本考案のテープガイドローラは、外周部自体と内周部に対する外周部の抜け止 め部、及び回り止め部を絞り加工で容易に作ることができ、内周部に対して外周 部の結合がずれてしまい、内周部と外周部が別々に回転してしまうことを防げる また、テープガイドローラ全体に占めるステンレス鋼の割合が少ないので、安 い材料費で、耐蝕耐磨耗性がよく、しかもテープとの摩擦抵抗の少ないテープガ イドローラを製造することができる。 In the tape guide roller of the present invention, the outer peripheral portion and the outer peripheral portion with respect to the inner peripheral portion, the retaining portion and the rotation preventing portion can be easily formed by drawing, and the outer peripheral portion is joined to the inner peripheral portion. It is possible to prevent the inner peripheral part and the outer peripheral part from rotating separately because they are misaligned. Also, since the proportion of stainless steel in the entire tape guide roller is small, the material cost is low, the corrosion resistance and abrasion resistance are good, Moreover, it is possible to manufacture a tape guide roller having a low frictional resistance with the tape.
