本発明は、本体ケースの前面に裏蓋付きの前蓋を備えた
テープカートリッジに係り、前蓋と裏蓋との間のダスト
シール構造に特徴を有する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tape cartridge having a front cover with a back cover on the front of the main body case, and a dust seal structure between the front cover and the back cover. Has characteristics.
この種のテープカートリッジでは、不使用時に外部から
塵埃が侵入してテープに付着すると、ドロップアウトな
どを招くので、前蓋と裏蓋との間のダストシールを確実
に行うことが望まれる。In this type of tape cartridge, if dust enters from the outside and adheres to the tape when not in use, it may cause dropouts, so it is desirable to ensure a dust seal between the front cover and the back cover.

ープ損傷を招くおそれがあった。In the above conventional example, the overlapping part of the lower edge of the front cover and the lower edge of the back cover is located inside the tape loading pocket, which is effective in improving sealing performance, but the brim is located inward from the lower edge of the front cover. It has a prominent structure. For this reason, the rotation locus of the tip of the brim is relatively close to the tape located between the front cover and back cover, and when the front cover is opened with the tape loosened, the tip of the brim will rotate the tape. There was a risk that the lower edge would get caught and cause damage to the tape.

。なお、裏蓋１３の下端は前記鍔２０の上面に近接して
おればよく、必ずしも完全に接触する必要はない。That is, the present invention has M'2413 on the front surface of the main body case 1.
In a tape cartridge equipped with a front lid 9, an inward flange 20 is provided at the lower end of the front plate 17 of the front lid 9, and the flange 20 is provided at an upper part of the flange 20 on the inner surface of the front plate 17.
A recessed portion 21 is formed that connects to the upper surface of. Thus, when the front cover 9 is in the closed position, the lower end of the back cover 13 enters the recess 21 and overlaps the collar 20. Note that the lower end of the back cover 13 only needs to be close to the upper surface of the collar 20, and does not necessarily need to be in complete contact with it.
不使用時に裏蓋１３の下端は、第１図に示すごとく本体

前蓋下端の内向き鍔２０上に重合しており、大気中の浮
塵が前蓋９と裏蓋１３との間のテープ走行空間に侵入し
難いラビリンス構造が得られる。When not in use, the lower end of the back cover 13 overlaps the inward facing flange 20 at the lower end of the front cover inside the pocket 5 formed on the front surface of the main body case 1, as shown in FIG. A labyrinth structure is obtained in which it is difficult for the tape to enter the running space between the front cover 9 and the back cover 13.
鍔２０は凹部２１の下方に連続形成されているので、該

作されても、鍔２０の先端でテープ２の下端を引っ掛け
ることはない。Since the flange 20 is continuously formed below the recess 21, even if the effective longitudinal length of the flange 20 is large, the amount of protrusion of the flange 20 from the inner surface of the front lid is small. The rotation locus is far away from the bottom end of the tape 2. Therefore, even if the front cover 9 is operated to open with the tape 2 slightly loosened forward, the lower end of the tape 2 will not be caught by the tip of the collar 20.
以上のようにした本発明によれば、前蓋下端とＭＷ上下
端の重合シール構造に簡単な改良を加えることで、該当
部位のダストシール性を高めながら前蓋開放時のテープ
の引っ掛は損傷をよく防止することができる。According to the present invention as described above, by adding a simple improvement to the overlapping seal structure of the lower end of the front lid and the upper and lower ends of the MW, the dust sealing performance of the relevant parts is improved, and the tape is not caught when the front lid is opened, causing damage. can be well prevented.
