本考案は、本体ケース内に介装されるライナー
シートの形状に特徴を有するテープカートリツジ
に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tape cartridge characterized by the shape of a liner sheet inserted within a main body case.

FIG. 9 shows an example of a conventional tape cartridge (Japanese Utility Model Publication No. 49-6571), between the upper and lower inner wall surfaces of the main body case 1 and the left and right hubs 4, 4 and the tape 3 wound thereon. Two upper and lower liner sheets 6, 6 are interposed therein. Each liner sheet 6 is shaped so that the portion between the front end 6a and the rear end 6b curls in a convex shape toward the sheet surface side, and the front and rear ends 6a, 6b are received and supported by the inner wall surface of the main body case 1. The convex curved surface between the front and rear ends 6a and 6b elastically clamps the hub end face and tape edge from above and below, and this elastic clamping action prevents the tape 3 from being wound around each hub 4 randomly.
しかし、この種のライナーシート６は前後端６
ａ，６ｂ間の距離（スパン）Ｌが大きいため、弾
性押圧力が弱く、使用しているうちに疲労して平
板状態になり、弾性挟持機能が早期に低下すると
ころに問題がある。 However, this type of liner sheet 6 has front and rear ends 6
Since the distance (span) L between a and 6b is large, the elastic pressing force is weak, and the problem arises in that it gets fatigued during use and becomes flat, resulting in early deterioration of the elastic clamping function.
そこでライナーシート６に各種の突条（折目）
を入れることが提案されている。例えば、実開昭
51−33416号公報では、第１０図および第１１図

止め、両突条２２，２２間を中凸状にカールさせ
てハブ端面に弾性接当させるものとなつている。 Therefore, various protrusions (folds) are formed on the liner sheet 6.
It is proposed to include. For example, Akira Jitsukai
51-33416, two parallel protrusions 22, 22 are inserted in the middle of the liner sheet 6 so as to straddle the hub 4, as shown in FIGS. 10 and 11.
Each of the protrusions 22, 22 is received by the inner wall surface of the main body case 1, and the protrusions 22, 22 are curled into a convex shape so as to come into elastic contact with the end surface of the hub.
尤も、第１０図および第１１図に示す従来のラ
イナーシート６は、自由状態において第１２図の
実線で示すように２本の平行な突条（折目）２

１２図の仮想線に示すごとく両突条２２，２２間

い。
However, the conventional liner sheet 6 shown in FIGS. 10 and 11 has two parallel protrusions (folds) 2 in the free state as shown by solid lines in FIG.
2 and 22 to make the cross section trapezoidal,
When assembled into the main body case 1 and subjected to the load of the hub 4 and tape 3, the rigidity of the sheet itself causes the space between the protrusions 22, 22 to curl into a convex shape as shown in the imaginary line in Fig. 12. It's nothing but a thing.
従つて、上記のライナーシート６は両突条２
２，２２間のカール性を長期に維持するのが困難
であり、そのカール高さも低い。更に各突条２
２，２２の両外側も中凸状にカールしておらず、
これら相まつてハブ４およびテープ３の弾性挟持
作用が不十分である。 Therefore, the above-mentioned liner sheet 6 has both protrusions 2
It is difficult to maintain curling properties between 2 and 22 for a long period of time, and the curl height is also low. Furthermore, each protrusion 2
Both outer sides of 2 and 22 are not curled in a convex shape,
Combined with these factors, the elastic clamping action of the hub 4 and tape 3 is insufficient.

イナーシート６の端縁２３がテープ３との摺接で
めくれ上がり、テープ３がライナーシート６の裏
側に回り込んでテープ走行不能を招くことにもな
る不利がある。 In particular, the edge 23 of the liner sheet 6, including the edge of the curled portion in the center, is floating away from the inner wall surface of the main body case 1.
Tape 3 comes into violent contact with the surface. This may cause tape damage or abnormal tape running noise. There is also a disadvantage that the edge 23 of the liner sheet 6 is turned up by sliding contact with the tape 3, and the tape 3 wraps around the back side of the liner sheet 6, causing the tape to become unable to run.

する。 Therefore, the present invention incorporates the advantages of inserting two parallel protrusions into the liner sheet and curling it into a convex shape, and further enhances the elastic clamping action of the hub and tape by the two upper and lower liner sheets. The purpose of the present invention is to securely improve the winding properties of the tape on each hub and the stability of tape running without any problems.

That is, the present invention has drive shaft insertion holes 2, 2 on the left and right sides of the center of the main body case 1, as shown in FIGS. Each drive shaft insertion hole 2, 2
A through hole 8, which corresponds to the drive shaft insertion hole 2, is provided between the upper and lower inner wall surfaces of the main body case 1, the left and right hubs 4, and the tape 3. The present invention is directed to a tape cartridge in which two upper and lower liner sheets 6, 6 each having holes 8 left and right are interposed therebetween.
そのうえで、本考案の内容を原理的に説明する
第１図において、各ライナーシート６には、左右

between each protrusion 14, 15 and the front and rear ends 6a, 6
The portions between the sheets b and b are each formed in a three-mountain shape that curls in a convex shape toward the sheet surface side. That is, the sheet center portion 16 between both protrusions 14 and 15 is formed into a convex curved surface that curls in a convex shape, and
Seat front part 1 between the front protrusion 14 and the front end 6a
7, and the seat rear portion 18 between the rear protrusion 15 and the rear end 6b are each formed to be curled in a convex shape.

According to the present invention, the liner sheet 6 is formed into a triangular shape with two parallel protrusions 14 and 15 on the front and back, each curling in a convex shape toward the sheet surface side. Ends 6a, 6
The four points b are received and supported by the inner wall surface of the main body case 1. Therefore, the front and rear ends 6 of the liner sheet 6
Unlike the conventional form in which a and 6b are curled in a single peak, each peak has a small front-to-back spacing (span) and is supported on both sides, so the curling property can be adjusted to the desired curl height. Can be maintained well over a long period of time. In addition, the front and back spacing S between both protrusions 14 and 15
is larger than the diameter of the through hole 8 and is the diameter D of the hub 4.
Therefore, each protrusion 14, 15 is set smaller than
Since the liner is continuous between the left and right sides, this also contributes to maintaining the shape retention, that is, the curlability, of the liner sheet 6. As a result, the elastic sandwiching function of the hub 4 and the tape 3 by the upper and lower two liner sheets 6, 6 is exhibited extremely well, and the winding performance of the tape 3 on each hub 4 and the stability of tape running are dramatically improved. It has advantages that can be improved.

4, 15 as well as the front and rear ends 6a, 6b are received and supported by the inner wall surface of the main body case 1.
and the rear end 6b are in close contact with the inner wall surface of the main body case without coming apart. Therefore, the tape edge does not come into sliding contact with the front and rear ends 6a, 6b of the liner sheet 6,
It is effective in preventing damage to the tape 3 and the sheet 6, as well as reducing the sliding noise when the tape is running, and also prevents the serious trouble of the tape 3 wrapping around the back side of the sheet 6 and involving the sheet 6. can also be reliably prevented from occurring.

The longitudinal distance S between the protrusions 14 and 15 is determined by the through hole 8.
The diameter of the liner sheet 6 is set to be larger than the diameter of the through hole 8 and smaller than the diameter D of the hub 4, and to roughly divide the liner sheet 6 into three in the front and back.
