Description

[Detailed explanation of the idea] [Industrial application field]

The present invention is used in the field of cassette tapes for recording, recording, etc. The present invention relates to a cassette tape with a re-recording plug, which is provided with a re-recording plug that is detachable.

[Prior art and its problems]

A conventional cassette tape has a hole at both ends or one end of the back of the case to prevent re-recording, and a recording claw is provided integrally with the case at the opening of the hole. With this cassette tape, after recording, if the content is important, the claws can be broken to allow the recording/recording machine to record.
The recording button is locked to prevent re-recording. However, if the recorded content is no longer needed, there is a problem that it cannot be re-recorded or re-recorded and the only option is to dispose of it. Furthermore, in the case of cassette tapes on which sound and video have been recorded in advance and the claws have been broken to prevent re-recording, there is a problem in that the tape cannot be re-recorded or re-recorded and must be disposed of. In order to prevent this waste, cassette tapes that enable re-recording by filling the hole provided in the opening with a plug have already been published in Japanese Patent Laid-Open No. 48-3514 and Utility Model Laid-Open No. 48-34517. Publication No. 49-45517
It was proposed in Japanese Utility Model Application No. 50-3525. However, the cassette tape disclosed in the above publication uses a hole to prevent re-recording and re-recording, and a latching recess is provided inside the hole, and the plug has a latching hole provided at the insertion end rather than the base end to prevent re-recording. Since the claws are wider, they have the following problems. (a) In all of the cassette tapes disclosed in the above publications, the plugs are buried in the holes, and the plugs are hooked to the cassette tape body, making it difficult to remove the filled plugs with bare hands. Therefore, a plug removal tool as shown in Japanese Utility Model Application Publication No. 48-34517 is required. (b) In the case of cassette tapes with extra holes, it is difficult to create a latching recess inside the hole, making it difficult to attach a plug and easy to remove the attached plug.

[Purpose of invention]

Therefore, the purpose of this invention is to remove the fixed idea that the re-recording prevention structure of a cassette tape forms a hole, and to fundamentally change the structure of the cassette tape without compromising compatibility, and to prevent the re-recording plug. To provide a cassette tape that is easy to attach and detach.

[Means to achieve the purpose]

The technical means of the present invention taken to solve the above problems are as follows. That is, the present invention provides a cassette tape having: a cassette tape main body in which a recess is formed on the back side of the case, penetrating from the top surface to the bottom; a reprinting plug fitted into the recess; and both side walls of the recess. A narrow portion is formed between the top and bottom surfaces of the case by narrowing the distance between both side walls, and the reprint plug has a narrow portion that engages with the narrow portion of the recess. This cassette tape with a reprinting plug is provided with a clamping surface that is flush or substantially flush with the top and bottom surfaces of the case when the tape is formed and mounted on the cassette tape body.

【Example】

The present invention will be explained in more detail based on embodiments shown in the drawings. The drawings show an embodiment of the present invention, and FIG. 1 is a perspective view showing a state in which one of the reprinting plugs is removed. In FIG. 1, reference numeral A indicates a cassette tape body, which houses a reel 11 and a magnetic tape 12 wound on the reel 11 in a case 1. A recess 3 for preventing reprinting is formed on the back surface 2 of the case 1. The recess 3 is formed in the shape of a groove penetrating the case 1 from the top surface 6 to the bottom surface 5. In the drawing, the recesses 3 are formed at both ends of the back surface 2 of the case 1,
It is not necessarily limited to both ends, and its position and number differ depending on the relationship with the audio/video recorder. Narrow width portions 30 are formed on the inner surface of the recess 3 so as to face each other in a raised manner. An elastically deformable reprinting plug 4 made of rubber, soft plastic, or having properties equivalent to these is fitted into the recess 3. The reprint plug 4 has a recess 3.
A narrow part 40 is formed to engage with the narrow part 30 formed on the inner surface, and the top surface 6 and bottom surface 5 of the case 1 are formed when the tape is attached to the cassette tape main body A.
Clamping surfaces 41 and 42 are provided which are flush with or substantially flush with. Furthermore, by further developing this example, reprint plug 4
By color-coding the re-recording plugs 4 filled into the left and right recesses 3, it is possible to easily identify the recording side or recording side of the cassette tape depending on whether one color is placed on the left or right side. It is convenient to be able to distinguish between Operation When performing audio/recording, the re-recording plug 4 is filled in the recess 3 and the tape is set in the audio/video recorder. If the recorded content is to be saved, the re-recording plug 4 can be removed from the recess 3 and the lock mechanism will operate to prevent re-recording even if the cassette tape is set in the audio/recorder. When attaching and detaching the re-recording plug 4, the holding surfaces 41 and 42 may be held between fingers. If the recording/recording content becomes unnecessary, re-recording or re-recording becomes possible by filling the re-recording plug 4 into the recess 3. It should be noted that the present invention is not limited to the above-mentioned embodiments, and many modifications can be made within the scope of the claims of the utility model registration.

[Effect of the idea]

The present invention has the following effects. (1) The cassette tape main body has a recess formed in the back of the case that passes through from the top surface to the bottom surface, and the re-recording plug that is fitted into the recess has a re-recording plug that is attached to the cassette tape main body. A clamping surface is provided which is flush with or substantially flush with. Therefore, the re-recording plug can be attached and removed by holding the gripping surface between the fingers, and additional re-recording plugs can be easily attached to the cassette tape body without the need for any equipment. (2) Further, a narrow width portion of the reprint plug is formed on the inner surface of the recess, and the reprint plug has a narrow portion that engages with the narrow width portion. For this reason,
The position of the re-recording plug does not shift when it is attached to the cassette tape body. (3) Compatible with conventional cassette tapes, requiring no modification to the tape recorder.
