Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a tape cassette, and more particularly, to a tape cassette containing a magnetic recording and reproducing tape used in a magnetic recording and reproducing apparatus such as a video tape recorder (VTR).

(Prior Art) As is well known, a conventional tape cassette of this type is constructed as shown in FIG. 1, for example. That is, as shown in the figure, the tape cassette 1 has a housing 2 formed in a rectangular shape, and both ends of the magnetic recording/reproducing tape 3 are placed at symmetrical positions in the housing 2. A tape supply reel 4 and a tape take-up reel 5 are fixed and wound respectively.
are arranged so as to be rotatable. The upper surface of the housing wall facing the left and right halves of both reels 4 and 5 is formed of a transparent material, and both reels 4 and 5 are made of transparent material.
The rotating state of the tape and the amount of tape wound around each can be seen from the outside. Further, an index sheet 6 for displaying the recorded contents of the built-in magnetic tape is attached to the back surface of the housing 2. In the figure, reference numeral 7 indicates a well-known erroneous erasure prevention claw.

By the way, in the above-mentioned conventional tape cassette 1, once the index sheet 6 is used to write a title and an index for displaying the contents according to the recorded contents of the magnetic tape, the next time other things are written on the magnetic tape 3. In order to record and rewrite the title and index, it was necessary to remove the sheet 6, leave it as is and stick a new index sheet, or delete the title, index, etc. and rewrite. but,
In any case, the work is extremely troublesome, and the product has the disadvantage that it ends up looking unsightly.

(Purpose) In view of the above points, the purpose of the present invention is to store a plurality of spare sheet-like index display bodies in a part of the cassette, so that it is extremely easy to store the previous index when it is no longer needed. A sufficient amount of index display can be stored in the tape cassette itself so that it can be replaced with a new display and can handle repeated index rewriting without having to reload a new display. We provide tape cassettes.

(Summary) The tape cassette of the present invention is provided with a display body storing means in a part of the cassette for storing a plurality of spare sheet-like index display bodies for displaying the recorded contents of the built-in magnetic tape. Depending on changes in the recorded contents of the magnetic tape in the tape cassette,
The present invention is characterized in that a new index display body can be taken out from the storage means, replaced with the previous display body, and fixed at a predetermined position.

(Example) The present invention will be explained below based on the illustrated example.

FIG. 2 is a partially cutaway plan view of a tape cassette showing one embodiment of the present invention;
This figure is a rear view of the tape cassette shown in FIG. 2 above. In Figures 2 and 3, components similar to those of tape cassette 1 in Figure 1 above are simply numbered.
10 will be added, and the explanation will be omitted unless there is a particular change.

Housing 12 in tape cassette 11 of the present invention
As shown in FIG. 2, an index display storage section 18 is disposed in the lower right corner of the display.
This storage section 18 is formed of a circular storage chamber, and a reel 19b rotatably fitted to a support shaft 19a is provided in the same chamber. A plurality of sheet-like index display members 23 are connected together and wound around the reel 19b in a tape-like manner. A display pull-out hole 20 penetrating toward the back surface 12a of the casing 12 is provided in the side wall on the back side of the storage chamber of the index display storage section 18. Further, as shown in FIG. 3, the tip of the index display 23 pulled out from the display pull-out hole 20 along the back surface 12a of the casing 12 is inserted into the back surface 12a of the casing 12. A fixing member 21 made of a vertically elongated piece of transparent plastic or the like is provided in parallel in the vertical direction near the center and left and right ends of the rear surface 12a of the casing to be attached and fixed to the rear surface 12a. There is. As one configuration of the fixing member 21 is shown in FIG. 4A, a cylindrical bearing portion 24a is formed on the inner surface of the upper end portion and projects in parallel with the upper side. The pin shaft fits into the notch 22 (see FIG. 4B) formed near the center and left and right ends of the upper end of the casing back 12a (see FIG. 4B), and the pin shaft extends horizontally in the center of the notch 22 21a
(See Figure 4B).
Further, a locking protrusion 24b is provided on the inner surface of the lower end of the fixing member 21.
In the state shown in FIG. 4A, that is, in the state in which it is in contact with the back surface 12a of the casing, it is press-fitted into the locking holes 25 provided at opposite positions on the back surface 12a of the casing, and the casing is in the state shown in FIG. 4A. A fixing member 21 is fixed to the back surface 12a of the body.

Next, the operation of the tape cassette 11 of the present invention constructed as described above will be explained.

FIGS. 2 and 3 show that the index display 23 wound around the reel 19b is inserted into the index display housing 18 from the display pull-out hole 20 along the back surface 12a of the casing. The magnetic tape 13 is pulled out and fixed by the fixing member 21 on the back surface 12a of the casing, and a display corresponding to the recorded content of the magnetic tape 13 built into the casing 12 is displayed, for example, "BIG-WEDNESDAY." ”, etc. are written. From this state, you can add recordings on the magnetic tape 13,
If it is necessary to change the display on the index display 23 by erasing and recording a new one, move the fixing member 21 from the state shown in FIG. 4A to the state shown in FIG. 4C. After rotation, the next index display 23 is pulled out from the spare display 23 wound around the reel 19b in the storage section 18 through the display pull-out hole 20, and the first one is pulled out. After cutting out one piece of magnetic tape and writing an indication according to the recording contents of the new magnetic tape on the next one, and attaching the same indicator 23 to the rear surface 12a of the casing, attach the fixing member 21 to the second piece. When the state shown in FIG. 4C is changed to the state shown in FIG. 4A, the new display body 23 is pressed against the rear surface 12a of the casing and is stably fixed.
That is, in response to changes in the recorded contents of the magnetic tape 13, the previous index display can be replaced with a new index display very easily.

(Effects) As explained above, according to the present invention, a spare index display is stored in the cassette housing, and the index can be displayed many times without having to reload a new display. The tape cassette itself contains a sufficient amount of index display that can be rewritten, and it is also extremely easy to replace the previous index display that is no longer needed. It is possible to provide a tape cassette which completely eliminates the drawbacks of the tape cassettes described above.
