Description

[Detailed description of the invention]

[Field of Industrial Application] The present invention provides a cassette tape adapter that has the same size and shape as a normal cassette tape, and a small and thin cassette tape. This relates to cartridge-type cassette tapes used for tR.

[Conventional Techniques] Using a cassette tape for recording and playback as an example,
Generally, cassette tapes for recording and playback are magnetic tapes, 2
It has two hubs and a frame called a half. The currently most popular cassette tape has a magnetic tape width of 3. It is called a 81 mm compact force set, and the magnetic tape is usually made of a polyester resin film base coated with needle-shaped magnetic metal crystals with a binder. That is, as shown in FIG. 17, the compact power center 50 for recording and reproducing is formed into a box shape and includes cassette halves 51, 51 made of thermoplastic resin and the cassette half 51.
, 51 rotatably supported within the hub 52 . 53 and
A magnetic tape 54 is wound around these hubs 52 and 53. [Problem that R-mei is trying to solve] Recently, portable Q-sweat playback tape recorders have become smaller and lighter, and their size has been reduced to the extent that the size is - around - larger than the size of a cassette tape. has also been developed, and the space used to store information has come to occupy a larger proportion than the hardware itself that performs recording and playback. Now that hardware is becoming more compact, there has long been a demand for smaller information storage spaces. On the other hand, as shown in FIG. 17, in the rear surface 57 of such a conventional compact cassette 50, recording/extinguishing detection recesses 55 are provided at both lengthwise ends of the cassette half 51. (In addition, in this recessed portion 55 for detecting recording erasure, a cutout piece 56 for preventing recording from sweating is provided at each end of the upper and lower two cassette halves 51, 51. When loaded into the recorder/player, the recording erasure detection protrusion (not shown in the figure) provided at the part corresponding to the upper recording sweat detection re-J cutout 56 is pressed by the Q.W detection cutout 56. The cassette 50 is configured so that a desired recording can be performed on the magnetic tape 54 by operating a recording switch 2 linked to this recording erasure detection protrusion. If you have recorded the content and want to save it without erasing it,
Break off the recording erasure detection notch 56 provided in the recording erasure detection four parts 55. In this case, the compact cassette 5 with the recording erasure detection notch 56 broken off
Even if the compact cassette 50 is loaded into the recorder, the recording erasure detection protrusion provided on the recorder will detect recording erasure when the compact cassette 50 is loaded into the recorder. As it moves into the recording recess 55, it becomes impossible to operate the recording switch of the recorder that is linked to this recording erasure detection protrusion, and the recording contents recorded on the magnetic tape 54 are further It is configured to prevent overlapping recording of other content. By the way, when a cassette tape is made smaller, the thickness of the cassette tape becomes thinner, and as a result, the length of the notch for detecting recording volume also becomes shorter. Therefore, in a miniaturized cassette tape, when trying to break off the Q-erasure detection notch to prevent recording contents from being erased, it becomes difficult to break it off, and the base end of the recording erasure notch becomes In some cases, it may not be possible to completely break off the tape, and a portion of the notch for detecting recording erasure may remain. In this way, when a compact force set 1.50 with a part of the notch for detecting recording erasure remaining is loaded into the recorder/player,
Because the protrusion for detecting recording and canceling is pressed against the remaining notch for detecting recording and canceling, the recording button becomes operable and there is a possibility that the recorded content may be erased by mistake. On the other hand, the Rffl erasure detection protrusion provided on the recorder/player was made smaller in order to accommodate the shorter recording erasure detection notch provided on the back of such miniaturized cassette tapes. Although it is conceivable that the recording erasure detection protrusions of the 15 recorders loaded with such small cassette tapes would have to be reinstalled, the manufacturing cost would be high. ．． In addition, in order to avoid such so-called double-erase erasure, an appropriate hole is prepared in advance on the back of the miniaturized cassette tape, and if you wish to save the recorded content, The configuration is such that the user can close the hole by pasting tape on the hole each time and prevent the recording erasure detection protrusion from entering the hole when loaded into the recorder/player. However, it is extremely troublesome to paste tape over the hole in the back of the cassette tape every time you want to save the recorded content. Therefore, the technical problem of the present invention is to miniaturize a cassette tape as an information storage space, and to make it possible to use the miniaturized cassette tape by loading it into a conventional compact cassette recorder/player. By using the recording erasure/erasure detection mechanism installed in the compact cassette recorder/player as is, the recording contents recorded on magnetic tape can be easily and reliably prevented from being erased by mistake without increasing manufacturing costs. The purpose is to do the following. [a! [Technical Means for Solving the Problem] In order to solve such a technical problem, the present invention provides a cassette tape body, a cassette tape body that can be housed and fixed, and a playback-only machine or a recorder. The cassette tape adapter has a set tape adapter that can be loaded, and a hole in the back of the cassette tape body into which a recording erasure prevention body can be removably inserted. A cassette tape adapter that is provided with a recording erasure detection member whose inner side surface abuts the end of the inserted recording sound erasure prevention body, and houses a cassette tape body in which the recorded sound erasure prevention body is inserted and disposed in a hole. is loaded into the recorder/player, the recording erasure detection protrusion provided on the recorder/player is pressed against the recording/erase detection member, and can operate the recording switch linked to the Q-blind erasure detection protrusion.

Therefore, it is possible to reduce the magnetic deterioration of the recorded magnetic tape 101, making it possible to prevent the recorded content from spontaneously erasing, and further minimizing the adhesion of dust to the magnetic tape 101 due to static electricity. This makes it possible. In addition, the cover panel portion 120 similarly deals with the itching heat generated by the high-speed running of the magnetic tape 101.
, 130, and as a result, the heat can be naturally radiated, making it possible to effectively prevent thermal deformation of the magnetic tape 101. Furthermore, the material of the magnetic tape 101 housed in the cassette tape body 100 according to this embodiment includes polyester, metal, and the like. Furthermore, the cassette tape body 100 according to this embodiment is configured so that it can be used alone without being housed and fixed in the cassette tape adapter 400. Recording/playing machines or playback-only machines with a configurable structure include:
The cassette tape wooden body 100 can also be used alone. Further, in the above embodiment, the cassette tape main body 10
The cover panel parts 120 and 130 constituting 0 are made of stainless steel, and are made of a metal with high magnetic permeability and conductivity. It may be configured. Furthermore, in each of the above embodiments, the cartridge type cassette tapes 10, 20, . 30 has been described as an example of recording audio, but the present invention is not limited to the above embodiments, and can also be applied to a VTR or DAT that also records or plays back images. Also,
It can be used not only for recording audio and images, but also as a storage medium (ROM) for electronic devices such as personal computers, word processors, and electronic still cameras. [Effects of the Invention] As described above, the present invention is capable of storing a cassette tape body and a wood body of the cassette tape, and can be loaded into a playback-only machine or a recording/playback machine. Because it is constructed from a cassette tape, the external dimensions of the standard size compact cassette are secured by a cassette tape adapter, and the size of the cassette tape body as an information storage space is larger than that of a conventional compact cassette. It can be made much smaller. Therefore, the cassette tape itself as a recording medium,
You can store far more cassettes in a limited space than conventional compact cassettes. Furthermore, the cassette tape itself as a recording medium is much smaller and thinner than conventional compact cassettes, making it possible to ensure good transportability and portability. Furthermore, according to the present invention, when the cassette tape body is housed in a cassette tape adapter, it can be used by loading it into a conventional cassette tape recorder/player. Further, in the present invention, a recording erasure prevention body is removably disposed on the back side of the cassette tape body, and a recording erasure detection member that can come into contact with the recording erasure prevention IL body is provided on the cassette tape adapter. When the cassette tape adapter containing the cassette tape body is loaded into the recorder/player, the recording erasure detection projection provided on the recorder/player is pressed by the recording erasure detection member. It is designed to be able to detect whether or not the person has deleted the recording. Therefore, the size of the cassette tape wooden body as an information storage space is much smaller than that of conventional compact cassettes, but the recording erasure detection mechanism of the recorder/player currently in use must be modified or remodeled. Moreover, it can be used as is, and it is possible to easily and reliably prevent the contents recorded on the magnetic tape from being erased by mistake without reducing the manufacturing cost of the cassette tape recorder/player.
