本発明は、テープリールの径方向への遊動量を接当規制
する規制壁に特徴を有するテープカートリッジに関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tape cartridge characterized by a regulating wall that abuts and regulates the amount of radial movement of a tape reel.
第４図は従来のテープカートリッジを示しており、プラ
スチック製の上下ケース１ａ−１ｂを突き合わせてなる
本体ケース１の内部に、テープ２が巻かれる一対のフラ
ンジ３付きリール４を有し、リール４は本体ケース１の
底壁に設けた駆動軸挿入孔５上にあって回転自在に収納
されている。FIG. 4 shows a conventional tape cartridge, which has a reel 4 with a pair of flanges 3 around which a tape 2 is wound inside a main case 1 formed by abutting upper and lower plastic cases 1a and 1b. is rotatably housed above the drive shaft insertion hole 5 provided in the bottom wall of the main body case 1.
本体ケース１の底壁の内面には、前記フランジ３の外周
を囲む部分円弧形状（半径Ｒ）の規制壁６が突設されて
おり、この規制壁６でリール４の径方向の遊動量を接当
規制している。A regulating wall 6 having a partial arc shape (radius R) that surrounds the outer periphery of the flange 3 is projectingly provided on the inner surface of the bottom wall of the main body case 1, and this regulating wall 6 controls the amount of radial movement of the reel 4. Contact is regulated.
リール４のフランジ３（半径ｒ）の外周と規制壁６の内
周との間には、リール４の回転時にフランジ３の外周が
接触しない程度の間隙を有する。There is a gap between the outer periphery of the flange 3 (radius r) of the reel 4 and the inner periphery of the regulating wall 6 such that the outer periphery of the flange 3 does not come into contact with each other when the reel 4 rotates.
従って、本体ケース１内において、リール４の径方向の
最大遊動量は、（Ｒ−ｒ）に設定され、デツキ側の駆動
軸が駆動軸挿入孔５を介してリール４に確実に係合する
ことを保証している。Therefore, within the main body case 1, the maximum radial movement amount of the reel 4 is set to (R-r), and the drive shaft on the deck side reliably engages with the reel 4 through the drive shaft insertion hole 5. I guarantee that.
問題は本体ケース１内のスペースなどの関係からフラン
ジ３の全外周囲にわたって規制壁６を連続状に設けられ
ない点にある。図示するごとくフランジ３の外周方向に
所定間隔をおいて断続的に部分円弧形状の規制壁６を設
けているのが実情である。The problem is that the restricting wall 6 cannot be continuously provided around the entire outer circumference of the flange 3 due to the space inside the main body case 1. As shown in the figure, the actual situation is that partially arc-shaped regulating walls 6 are provided intermittently at predetermined intervals in the outer circumferential direction of the flange 3.
そこでは隣合う規制壁６・６間でリール・フランジ３の
円周一部が突き出るため、実際の遊動量は（Ｒ−ｒ）よ
り僅かに大となる。特に、本体ケース１の前面側の左右
に開口したテープ引出ロアの開口幅が広いテープカート
リッジでは、リール４のテープ引出口方向への位置（破
線Ａで示す）において、リール４の遊動量が最大となる
。In this case, a part of the circumference of the reel flange 3 protrudes between the adjacent regulating walls 6, 6, so the actual amount of free movement is slightly larger than (R-r). In particular, in a tape cartridge where the opening width of the tape drawer lower openings on the left and right sides of the front side of the main body case 1 is wide, the amount of free movement of the reel 4 is maximum at the position toward the tape drawer opening of the reel 4 (indicated by the broken line A). becomes.
このようにリール４の遊動ガタが大きい場合は、リール
４と本体ケース１の内壁との摩擦により摩耗粉が発生し
やすく、またテープ２のエツジもフランジ３の先端で傷
つけられやすい。When the reel 4 has a large play as described above, abrasion powder is likely to be generated due to friction between the reel 4 and the inner wall of the main body case 1, and the edge of the tape 2 is also likely to be damaged by the tip of the flange 3.
特に、リール４がテープ引′出ロアの方向へ大きくガタ
ついた場合、不使用時にリール４はブレーキ手段で回転
規制されてテープ２の巻き締まりで前述のＡ位置に固定
されてしまい、リール中央の駆動穴８がデツキ側の駆動
軸と嵌まり合わないという最悪の事態を招きかねない。In particular, if the reel 4 wobbles significantly in the direction of the tape pull-out lower, the rotation of the reel 4 will be restricted by the brake means when not in use, and it will be fixed at the above-mentioned position A due to the tightness of the tape 2, and the reel 4 will be at the center of the reel. This could lead to the worst situation in which the drive hole 8 of the drive shaft does not fit with the drive shaft on the deck side.
このようにリール４がテープ引出ロアの方向へ必要以上
に遊動するのを接当規制するために、本発明者は第、４
図中の二点鎖線Ｆおよび第５図に示すごとくテープ引出
ロア側にも規制壁９を設けることを検討した。In order to prevent the reel 4 from moving more than necessary in the direction of the tape drawer lower, the inventors have developed the fourth
We considered providing a regulating wall 9 also on the tape drawer lower side as shown in the two-dot chain line F in the figure and in FIG.

すく、遊動規制機能を有効に発揮できず、更にその乗り
上がりでテープ２を傷めやすいといった事態が懸念され
る。When such a regulating wall 9 is provided on the inner surface of the bottom wall of the case, unlike the existing regulating walls 6 in other parts, it is necessary to set the protruding height so that it does not come into contact with the lower edge of the tape 2 when the tape runs. Therefore, as shown in FIG. 6, the lower flange 3 of the reel 4 tends to remain on the low regulating wall 9, making it impossible to effectively exert its play regulating function, and furthermore, the tape 2 is likely to be damaged by the lower flange 3 of the reel 4. There are concerns.
そこで本発明の目的は、テープ引出口側に規制壁を設け

きるテープカートリッジを得るにある。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a tape cartridge in which a regulating wall is provided on the tape outlet side, and the regulating wall is further devised to more stably and reliably restrict the movement of the reel toward the tape outlet. It is in.

が形成されていることを要件とする。That is, in the present invention, on the inner surface of the bottom wall of the main body case 1, between the lower flange 3 of the reel 4 and the tape drawer lower, a regulating wall 10 for regulating the amount of radial movement of the reel 4 is provided around the outer periphery of the lower flange 3. The protruding height H of the regulating wall IO is set so as not to contact the tape 2 during tape running, and the inner surface of the regulating wall 10 facing the lower flange 3 has Tapered surface portion 11 that expands upward
is required to be formed.

用を受けて、リール４が該規制壁１０の内側に滑り落ち
る。When the reel 4 receives a strong tensile force due to an external impact or the like while it is close to the tape drawer lower side, the lower flange 3 of the reel 4 tends to ride on the regulating wall 10 at the relevant portion. At this time, the lower flange 3 is subjected to a sliding guide action on the tapered surface portion 11, and the reel 4 slides inside the regulating wall 10.
〔発明の効果）
従って本発明によれば、まず規制壁１０でリール４がテ

４のテープ引出ロア側への大きな遊動を有効確実に規制
でき、下フランジ３が規制壁１０に乗り上がることによ
るテープ損傷などの問題もよく解消できる。At this time, although the regulating wall 10 is formed low to avoid contact interference with the tape 2, even if the lower flange 3 of the reel 4 tries to climb onto the regulating wall 10 due to external vibration, the lower flange Since the outer periphery of the lower flange 3 is stopped by the tapered surface portion 11, the lower flange 3 slides inside the restriction wall 10 due to the guiding action of the tapered surface portion 11, and remains on the restriction wall 10. It will never be. Therefore, large movement of the reel 4 toward the tape drawer lower side can be effectively and reliably restricted, and problems such as damage to the tape caused by the lower flange 3 riding on the restriction wall 10 can be well resolved.
