Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an audio or video tape cartridge, and more specifically, it is characterized by how to attach an index card to the outer surface of a main body case.

[0002]

[Prior Art]

 Recently, as a tape cartridge of this type, unlike the conventional analog compact cassette (CC) in which drive shaft insertion holes are formed through both upper and lower sides of the main body case, the drive shaft insertion hole has a lower surface of the main body case. A digital compact cassette (DCC) is proposed, which is opened only on the wall and has no drive shaft insertion hole on the upper wall (Japanese Patent Laid-Open No. 3-44857). Since there is no drive shaft insertion hole in the top wall of the case, almost the entire surface can be used as a space for the title label. In addition, there is a tape cartridge for data backup of a computer that has a hole cover plate that covers the drive shaft insertion hole on the top wall of the main unit case and allows you to write a title on the hole cover plate. It has been proposed (JP-A-3-134879).

[0003]

[Problems to be solved by the device]

 However, in any of the above tape cartridges, the title label and the hole cover plate are attached to the concave portion provided on the upper surface wall of the main body case in an exposed state, so that the written characters can be displayed with a finger or the like with long-term use. It is rubbed and becomes thin or disappears. Especially in a high temperature environment such as in a car in the summer, the title label is easily lifted or peeled off, which may cause troubles when putting it in or out of the player. However, if the title label is covered with a transparent cover on the outer surface of the main body case, that is, if the transparent cover is integrally bonded to the main body case by ultrasonic welding, etc., the title label can be inserted and removed. In addition, it is inconvenient because it cannot be written or rewritten. The purpose of the present invention is to solve these problems, improve the durability of the index card, and prevent the characters written on the index card from fading or disappearing. Another object of the present invention is to facilitate the taking in and out of the index card, and the writing and rewriting of the index card.

[0004]

[Means for Solving the Problems]

 In the tape cartridge of the present invention, as shown in the illustrated example, a recess 17 for accommodating the index card 16 is formed on the outer surface of the top wall 5 of the main body case 1, and the recess 17 is opened and closed by a transparent cover 19. It was done.

[0005]

[Action]

 In the closed state of the transparent cover 19, the index card 16 is covered in a see-through manner so that the index card 16 can be protected from scratches, stains, fading or loss of characters. By opening the transparent cover 19, the index card 16 can be easily taken in and out of the recess 17.

[0006]

[Effect of the device]

 According to the present invention, since the transparent cover 19 which covers and protects the index card 16 is opened and closed with respect to the recess 17 of the upper surface wall 5 of the main body case 1, the index card 16 can be inserted into the recess 17. It is convenient because it can be easily put in and taken out, and writing and rewriting to it are possible.

【Example】

 The drawing shows an embodiment applied to a digital compact cassette (DCC). The basic form of this tape cartridge is substantially the same as that of the analog type compact cassettes used so far. 1 to 4, the main body case 1 is formed by abutting upper and lower plastic cases 1a and 1b and integrally connecting them with each other with screws or the like. As shown in FIG. 3, a drive shaft insertion hole 4 is formed in the lower surface wall 3 of the lower case 1b at the left and right of the central portion of the lower case 1b, but the DCC is not turned over by auto-reverse and is not used. Is in a blind wall state having no drive shaft insertion hole 4. In the main body case 1, a hub 7 around which a tape 6 is wound on each drive shaft insertion hole 4 is rotatably accommodated and arranged. The tape 6 is unwound from one hub 7 and is wound around the other hub 7 via guide rollers 9 arranged on the left and right of the front surface side in the main body case 1. As shown in FIG. 4, a magnetic recording / playback magnetic head insertion window 11 is opened at the center of the front wall 10 of the main body case 1 in the horizontal direction facing the tape running path between the left and right guide rollers 9. A pinch roller insertion window 12 is opened on the left and right of the window.

Since the DCC is a high-density recording, as in the case of DAT, a slide type shutter 14 is used to open the drive shaft insertion hole 4 of the lower wall 3 and the insertion windows 11 and 12 of the front wall 10 as shown in FIG. It is closed when not in use to protect the tape 6 from dust and scratches. As shown in FIG. 3, the shutter 14 includes a bottom plate 14a formed on the outer surface side of the lower surface wall 3 by a stainless steel plate or the like having a U-shaped cross section, and a front plate 14b located on the outer surface side of the front surface wall 10. , The upper plate 14c located on the front end side of the upper surface wall 5 is integrally formed, and slides in the left-right direction between a position where the drive shaft insertion hole 4 and each insertion window 11 and 12 are closed at the same time, and an opening position. It is freely incorporated.

Almost the entire outer surface of the upper surface wall 5 of the body case 1 and substantially the entire outer surface of the rear surface wall 15 are used as a space for accommodating the index card 16. As shown in FIG. 1 and FIG. 3, recesses 17 and 18 for accommodating the index card 16 bent into an L-shaped cross section are communicated from almost the entire outer surface of the upper wall 5 to almost the entire outer surface of the rear wall 15. A transparent cover 19 that is formed in a shape and covers the index card 16 is attached to the recess 17 so as to be openable and closable. The transparent cover 19 is made of hard transparent plastic and has an L-shaped cross section. The upper plate 19a is fitted in the recess 17 of the upper wall 5 and the rear plate is fitted in the recess 18 of the rear wall 15. It has 19b and one. As shown in FIG. 5, small protrusion-shaped pivots 20 are provided on both left and right front sides of the upper plate 19a, and the pivots 20 are engaged with the shaft holes 21 formed in the recesses 17 to pivot the shafts. The transparent cover 19 can be freely opened and closed around 20. In the opening / closing operation, the rear plate 19b can be used as a handle. A cutout 28 is provided on one side of the recess 17 of the upper surface wall 15 so that the index card 16 can be easily picked up from the recess 17 with a fingertip.

The transparent cover 19 can also pivotally connect the rear plate 19b to the body case 1 in a rotatable manner. That is, as shown in FIGS. 6 to 8, the transparent cover 19 is provided at the front end of the upper plate 19a with an engaging piece 23 that can be inserted and removed in the front-rear direction with respect to a thin hole 22 that is opened in the recess 17 of the main body case 1 on the front end side. To provide. Then, as shown in FIG. 8, a pair of left and right shaft support arms 25, which are inserted from the inner surface of the rear plate 19b into the holes 24 of the rear wall 15 of the main body case 1, are provided so as to project forward, and the shaft support arms 25 are also provided. A pivot 20 is provided in the left-right direction at the tip of the shaft 20, and the pivot 20 is inserted into a shaft hole 27 opened in the left and right side walls 26 of the main body case 1. The shaft hole 27 has circular hole portions 29 and 30 at the front and rear that are slightly larger than the diameter of the pivot shaft 20, and is formed in a shape in which the circular hole portions 29 and 30 are connected by a long hole portion 31 that is slightly smaller than the diameter of the pivot shaft 20. is doing. At this time, the transparent cover 19 inserts the engaging piece 23 into the thin hole 22 of the main body case 1 and engages it, and the pivot 20 is positioned in the circular hole 29 on the front side of the shaft hole 27.・ Keep 18 closed. When the transparent cover 19 is moved a little rearward from this closed state as shown by the chain double-dashed line in FIGS. 6 and 8, the engaging piece 23 is pulled out from the thin hole 22 and the pivot 20 is circular in the front side. It moves from the hole 29 to the circular hole 30 on the rear side through the long hole 31, and in this state, the transparent cover 19 can be opened and rotated upward around the pivot 20 as shown in FIG.

If the transparent cover 19 is pivotally connected to the main body case 1 as in the above-described embodiment, it is advantageous that the transparent cover 19 is not detached from the main body case 1 and lost. The cover 19 may be locked to the main body case 1 in the normal state, and may be completely removed from the main body case 1 when opened. In the above-mentioned embodiment, since the index card 16 is bent into an L-shaped cross section, the recess 18 for accommodating it is also formed in the rear surface wall 15. However, if the index card 16 is flat, the rear surface wall is formed. It is not always necessary to provide the concave portion 18 in 15. Therefore, the transparent cover 19 may open and close at least the concave portion 17 of the upper surface wall 5.
