(産業上の利用分野)
本考案は、カセツトテープのケースの内面とテ
ープ巻回体との間に介挿される滑性シートに関す
る。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a slippery sheet inserted between the inner surface of a cassette tape case and a tape roll.
(従来の技術)
従来、この種の滑性シートとして成形時に弓状
に彎曲形成されたものや複数個の大きなドーム状
の突出部が等間隔に形成されたものが知られてい
る。(Prior Art) Conventionally, as this type of slippery sheet, there are known sheets that are curved into an arch shape during molding and sheets that have a plurality of large dome-shaped protrusions formed at equal intervals.
(考案が解決しようとする問題点)
従来の前記滑性シートの前者は、彎曲度にばら
つきがあると共に長時間使用しているうちに疲労
して平板に近い状態になりテープ巻回体を弾性的
に挟持する機能が減退して摩擦力が大きくなるた
め磁気テープが巻き乱れたり、巻取りトルクのば
らつきを生ずるという不都合があり、また後者
は、ドーム状突出部とテープ巻回体との弾性接触
のため前者より摩擦力が小さいが未だ充分ではな
い不都合があつた。(Problems to be solved by the invention) The former of the above-mentioned conventional slippery sheets has variations in the degree of curvature and becomes fatigued after long-term use, becoming almost like a flat plate, causing the tape roll to become elastic. This has the disadvantage that the magnetic tape is wound unevenly and the winding torque is uneven because the gripping function is reduced and the frictional force increases. Due to the contact, the frictional force is smaller than the former, but it still has the disadvantage that it is not sufficient.
本考案は従来のかかる不都合のないカセツトテ
ープ用滑性シートを提供することをその目的とし
たものである。 The object of the present invention is to provide a slippery sheet for cassette tapes that does not have the above-mentioned disadvantages.
(問題点を解決するための手段)
本考案は、ケースの内面とテープ巻回体との間
に介挿される滑性シートにおいて、多数個のボス
が該滑性シートの内側から外側縁の方向に複数列
に配列されて形成され、且つ内側から外側縁に向
つてボスの間隔が順次広く形成され、該ボスの突
出方向とは反対方向に湾曲していることを特徴と
する。(Means for Solving the Problems) The present invention provides a slippery sheet inserted between the inner surface of a case and a tape roll, in which a large number of bosses are arranged in a direction from the inside to the outer edge of the slippery sheet. The bosses are arranged in a plurality of rows, the intervals between the bosses are gradually widened from the inner side toward the outer edge, and the bosses are curved in the opposite direction to the protruding direction of the bosses.
(実施例)
第1図及び第2図は本考案の一実施例を示す。
同図において、1は滑性シートSの面にプレス成
形された円形、4角形等のボスで、該ボス1は滑
性シートSの長尺辺と平行の中心軸Lから両長尺
辺の方向に複数列に配列されて形成され且つ中心
軸Lから長尺辺に向つてボス1の間隔が順次広く
形成されている。このボス1の配列構成により、
滑性シートSは、中心軸を中心にして左右対称的
にボス1の突出方向とは反対方向に湾曲する。(Embodiment) FIGS. 1 and 2 show an embodiment of the present invention.
In the figure, reference numeral 1 denotes a circular, square, etc. boss press-formed on the surface of the slippery sheet S, and the boss 1 extends from the central axis L parallel to the long side of the slippery sheet S. The bosses 1 are arranged in a plurality of rows in the direction, and the intervals between the bosses 1 gradually become wider from the central axis L toward the long sides. Due to this arrangement configuration of boss 1,
The slippery sheet S curves symmetrically about the central axis in a direction opposite to the direction in which the boss 1 projects.
この湾曲された滑性シートSは、第3図及び第
4図に示すように、ボス1の突出側をテープ巻回
体2に向けて上ケース3及び下ケース4とテープ
巻回体2の間に彎曲されながら介挿される。 As shown in FIGS. 3 and 4, this curved slippery sheet S is attached to the upper case 3, the lower case 4, and the tape roll 2 with the protruding side of the boss 1 facing the tape roll 2. It is inserted in a curved manner in between.
かくてカセツトテープの組立状態において、滑
性シートSのボス1はテープ巻回体2の側面に弾
性的に圧接し、小さな摩擦力でテープの巻き乱れ
を防止する。 Thus, in the assembled state of the cassette tape, the boss 1 of the slippery sheet S comes into elastic pressure contact with the side surface of the tape winding body 2, and prevents the tape from being undone by a small frictional force.
第5図乃至第7図は本考案の他の実施例を示
す。 5 to 7 show other embodiments of the present invention.
同図において、5はテープの駆動軸が挿通する
透孔で、前記ボス1はこの透孔5を中心にしてシ
ートSの長尺辺及び短尺辺に向かつて放射状に複
数列に配列されて形成され、透孔5から長尺辺及
び短尺辺に向かつてボス1の間隔が順次広く形成
されている。このボス1配列構成により、滑性シ
ートSは、透孔5を中心にしてほぼ3方向が対称
的にボス1の突出方向とは反対方向に湾曲する。 In the figure, reference numeral 5 denotes a through hole through which the drive shaft of the tape is inserted, and the bosses 1 are arranged in multiple rows radially toward the long and short sides of the sheet S with the through hole 5 as the center. The intervals between the bosses 1 are gradually widened from the through hole 5 toward the long side and the short side. Due to this arrangement of the bosses 1, the slippery sheet S curves symmetrically in approximately three directions around the through hole 5 in a direction opposite to the direction in which the bosses 1 protrude.
かくて、カセツトテープの組立状態において、
滑性シートSのボス1は、テープ巻回体2の側面
に第3図及び第4図示のものより均一に弾性的に
圧接する。 Thus, when the cassette tape is assembled,
The bosses 1 of the slippery sheet S come into pressure contact with the side surfaces of the tape roll 2 more uniformly and elastically than those shown in FIGS. 3 and 4.

いなどの効果を有する。(Effect of the invention) According to the invention, a large number of bosses are arranged in a plurality of rows from the inside to the outside edge of the sheet, and the intervals between the bosses gradually become wider from the inside to the outside edge. As a result, the sheet is curved in the opposite direction to the protruding direction of the boss, so there is less variation in the degree of curvature compared to conventional sheets, and even after long-term use, it will remain close to a flat plate due to fatigue. Therefore, the frictional force is small over a long period of time, and its variation is small, and there are effects such as less uneven rotation and less irregular winding of the magnetic tape.
