[Conventional technology]

The prior art will be explained based on FIG. 6. Figure 6 shows a tape cassette and its storage case. FIG. A small video tape recorder used in video cameras, etc. For example, there is a VHS-C (registered trademark) type tape cassette for players. , the storage case K of this tape cassette G consists of a storage case body 31 and a rotating automatic storage case body 31. It consists of a storage case lid 32 pivotally attached to the front surface of the tape cassette G. A front cover 9 for tape protection on the side is pivoted around a horizontal axis 10 so as to be freely openable and closable. It is equipped with a locking mechanism that locks the lid in the closed state.

0003 The tape cassette G is provided with a pair of reel hubs on which magnetic tape is stretched. The figure shows the hub 16 on the tape supply side and the flange 8 of the reel on the tape take-up side. It is shown. Store the tape cassette G in the main body 31 of the storage cassette case K. When the storage case lid 32 is closed, the hub 16 and the flange 8 are The hub 16 engages with the convex portions 17 and 18 provided on the side of the cover 32, respectively, and Unnecessary rotation of the flange 8 is suppressed. When not using the tape cassette, A locking member for locking the lid 9 in the closed state is built into the tape cassette G. There is. Tape cassette G has a , a lock release protrusion 7 is provided for releasing the front cover 9 from the closed state.

0004 The lock release protrusion 7 is provided outside the case of the tape cassette G so that it can freely protrude and retract. When the tape cassette G is used, the protrusion 7 is attached to the case of the tape cassette G. The front cover 9 is pressed inward, and the front cover 9 becomes freely openable. Cassette G When stored in the storage case K, the protrusion 7 is attached to the storage case main body. An opening C is provided in the storage case main body 31 so as not to receive stress from contact with the side wall of the storage case 31. It is written.

[0005] The above is a general explanation of FIG. 6, but the lid 32 of the storage case K shown in FIG. Since there are the protrusions 17, 18, etc. on the inside of the tape cassette G, Storage in K must be performed in the direction shown in FIG. For example, a tape cassette Even if I tried to store G upside down in storage case K, it would be impossible. , which is very inconvenient for storage and operation.

[0006] Therefore, we removed the protrusion from the storage case to prevent the reel hub from rotating, and the tape cassette A tape cassette has been proposed that allows tape storage from multiple directions. this is , a pair of reel hubs with magnetic tape stretched over them, and unnecessary parts of the pair of reel hubs.
