止を図り、テープ保護の完全性を図る点にある。The problem here is that the front lid, the back lid and the upper lid are connected to each other so that they can be bent freely. In this case, the connecting portion between the front lid and the upper lid, and the upper lid and the back lid are connected. A gap is formed in each of the connecting portions with the dust, and the dust easily enters through the gap, and there is a concern that the function of protecting the tape from dust adhesion by the front lid, the back lid, and the upper lid may be reduced. In particular, in the above-mentioned proposal previously proposed by the present applicant, as shown in FIG.
Is pivotally connected between left and right bearings 40 provided on the inner surface side of the upper lid 11 so as to be rotatable around a pivot 41.
1 and the upper end 10a of the back cover 10, there is a gap for securing the rotation of the back cover 10, and since the gap is in an open state, dust entering from below the pocket 6 is There is a problem in that it easily enters through the gap and adheres to the tape 2. SUMMARY OF THE INVENTION An object of the present invention is to provide a tape cartridge having a front lid, an upper lid and a back lid as described above, in which the inner surface of the upper lid and the upper end of the back lid are improved by improving the pivot connection structure of the upper lid and the back lid. Another object of the present invention is to prevent dust from intruding from between the mating surfaces and to achieve complete protection of the tape.

Can come off. Although a small gap is formed between the lower peripheral surface of the back cover holding wall 27 and the wrapping wall piece 32, the lower peripheral portion of the lower end of the back cover holding wall 27 is covered with the wrapping wall piece 32. Therefore, the gap goes as far as possible inward and outward so as to form a curved passage. Therefore, dust entering from below the pocket 6 or from between the overlapping surfaces of the upper lid 11 and the upper wall of the main body case 1 is exposed to the tape 2 in the pocket 6 from between the inner surface of the upper lid 11 and the upper end 10a of the back lid 10. It is difficult to invade the place where there is. As shown in FIG. 1, a concave portion 36 is provided on the inner surface of the lower end portion of the main face plate 12 of the front lid 9, and the lower end portion of the back lid 10 is abutted against the concave portion 36, thereby preventing dust from entering therefrom.
