この発明はカセットテープの消去禁止と消去可能の切り
替え構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for switching a cassette tape between erasable and erasable.
この適用は音楽用、音声用、情報処理□用、ＶＴＲ用等
、他方面のカセットテープに可能である。This application can be applied to cassette tapes on the other side, such as those for music, audio, information processing, VTR, etc.
カセットテープは第１図に示すような外観をしており、
使用方法はカセットテープ１をカセットデツキに装着し
カセットテープ内に装填されている磁気テープに音声等
を録音したり、録音されている内容を再生したりするも
のである。A cassette tape has an appearance as shown in Figure 1.
The method of use is to load the cassette tape 1 into a cassette deck, record audio, etc. on the magnetic tape loaded in the cassette tape, and play back the recorded contents.
従来、録音されている内容を、ある期間消去できなくし
たい場合には消去禁止ツメ３を根元より折り、誤ってカ
セットデツキを操作ミスしても当該カセットテープに録
音されている内容を消去することの無いようにしていた
。Conventionally, if you want to prevent recorded content from being erased for a certain period of time, you can fold the erasure prohibition claw 3 from the base, and even if you accidentally operate the cassette deck, the content recorded on the cassette tape will be erased. I tried to make sure there wasn't any.
しかし、この構造の場合、一度折った消去禁止ツメ３は
、再度使用することが出来ないために下記の不具合点が
あった。However, in the case of this structure, the erasure inhibiting claw 3, once broken, cannot be used again, resulting in the following disadvantages.
（１）誤って消去禁止ツメ３を折ってしまった場合、当
該カセットテープは録音用としての機能を有しなくなる
。(1) If the erasure prohibition tab 3 is accidentally broken, the cassette tape will no longer have a recording function.
（２）ある期間に限定し、一時的に録音内容を消去禁止
にしたい場合には、細心の注意を払って、カセットテー
プの装着、カセットデツキの操作をする必要がある。(2) If you want to temporarily prohibit erasure of recorded content for a certain period of time, you need to be very careful when loading the cassette tape and operating the cassette deck.
（３）上記（２）でも心配な場合、思い養って消去禁止

がある。(3) If you are still worried about (2) above, try to think carefully and intentionally break the erasure prohibition claw 3, and once you have achieved your goal, block the erasure inhibition detection switch space 4 with duct tape or sellotape, etc. to prevent erasure. There is a method of using it as a substitute for the claw 3, but there is a risk that duct tape or cellophane tape may adhere to the erasure prohibition detection switch section on the cassette deck side, causing a malfunction.

Instead of the traditional one-time use system, the erasure lock can be switched between recording prohibition and recording as many times as the user needs, without removing the erasure prohibition tab from the main body of the tape. Inventor Guo was
This is the erasure inhibited section 2 of the cassette tape shown in FIG. The specific structure of this is shown in Figures 3, 4, 5, and 6.
The tree explained based on each figure of FIG.
始めに第３図の構造例−１について説明する。First, structural example-1 shown in FIG. 3 will be explained.

きをし、録音テープは録音可能状態になる。One end of an opening/closing plate A5 that can freely open and close the erasure inhibition detection switch space 4 is attached to an opening/closing plate mounting shaft 8. As a result, the opening/closing plate A5 can freely move in the direction of the arrow shown in the drawings around the opening/closing plate mounting shaft 8. By tilting the opening/closing plate A5 all the way to the left, the stopper A6 and the stopper B
7, the opening/closing plate A5 functions as an erasure prohibition/removal mechanism 3, and the recording tape becomes ready for recording.

より可能となる。Next, in order to temporarily prevent the recorded content from being erased due to erroneous operation of the skein, notebook, etc., insert your fingernail or the tip of a mini dry knife into the opening/closing plate removal opening A9. Erasing can be easily inhibited by removing the opening/closing plate A5 fixed therebetween, tilting it toward the right direction of the arrow, and storing it in the stopper A6. Next, if the recorded content of the recording tape that has been temporarily set to erasure-inhibited status is no longer used and you wish to store it again as a recordable tape, remove the opening/closing plate A5 from the stopper 6 and push it all the way to the left in the same way as described above. This becomes possible by fixing again between the tilting stopper A6 and the stopper 87.
次に第４図の構造例−２について説明する。Next, structural example 2 shown in FIG. 4 will be explained.

It has a structure that allows it to move freely in the direction of the arrow.As explained in Figure 3, moving the opening/closing plate BIO all the way to the left enables recording, and moving it all the way to the right disables recording. become a state. The gap between the opening/closing plate B1, 0 and the opening/closing plate guide All is designed to have a frictional force to the extent that the opening/closing plate BIO does not shift due to shock during normal use. In addition, if this gap is widened to reduce the frictional force, it is necessary to provide a stopper to prevent the opening/closing plates from shifting when the opening/closing plates are set in both left and right directions.
次に第５図の構造例−３について説明する。Next, structure example 3 shown in FIG. 5 will be explained.

The switch space 4 is provided, and the opening/closing plate C13 is structured to move freely in the direction of the arrow.As explained in FIG. If you move all at once, recording will be disabled. In addition, the opening/closing plate C゛13 and the opening/closing plate guide B
The gap 14 is the same as that explained in FIG.
次に第７図の構造例−４について説明する。Next, structural example 4 shown in FIG. 7 will be explained.

。In the case of a cassette tape in which a high-gain magnetic tape such as metallic or chrome is loaded on the right side of the erasure inhibition detection switch space 4 of the cassette tape as shown in FIG. 6, this is the high-gain magnetic tape. This is an explanation of a method of applying the present invention to a cassette tape in which a 1-gain magnetic tape detection switch space 16 is provided so that the cassette deck side can identify this.

出スイッチ空間１６を設けることにより可能である。This is an opening/closing plate in which a high gain magnetic tape detection switch space 16 is added to the right side of the erasure inhibition detection switch space 4 in Structure Example 2 of FIG. 4, and the opening/closing plate guide All is extended to the right end of the high gain magnetic tape detection switch space 16. It has a structure with a guide C17, and as in the explanation in FIG. 4, by passing the opening/closing plate BIO over the high gain magnetic tape detection switch space 16 and moving it all the way to the left, it becomes ready for recording, and then moves to the right. If you move all at once, recording will be disabled. Incidentally, the gap between the opening/closing plate BIO and the opening/closing plate guide C17 is the same as that explained in FIG. 4. , On the other hand, regarding the structure of FIG. 5, in the case of a cassette tape having a high gain magnetic tape detection switch space 16, the right end of the erasure inhibit detection switch space of FIG. This is possible by providing a high-gain magnetic tape detection switch space 16 in.

も、かつ任意の期間、設定したり解除したりできる。In this case, as described in 1 above, when setting the cassette tape in erasure-prohibited state, there is no need to remove the erasure-inhibiting tab from the cassette tape body, which corresponds to the opening-closing plate of the present invention. This opening/closing plate can be moved freely in the direction of the arrow in each figure as many times as desired, and is structured so that it will not come off due to shock during normal use. (1) Depending on the user's needs. , the same cassette tape can be put in or out of the recordable state any number of times and for any period of time on the cassette tape side.

ープの節約に結びつく。(2) Because of this, we want to reliably prevent erroneous recording for a certain period of time, so we have no choice but to use the deletion prohibition tab 3.
Since the cassette tape is folded, it can only be used for playback, which eliminates waste and saves cassette tapes.
（３）カセットテープを節約するために消去禁止検出ス

。(3) In order to save cassette tapes, the erasure inhibition detection switch space 4 is covered with duct tape, sellotape, etc., so that it is no longer used as a substitute for the erasure inhibition claw 3, and the erasure inhibition detection switch section on the cassette deck side is covered with duct tape. This eliminates malfunctions caused by adhesion of cellophane or cellophane tape.
（４） ハイゲイン磁気テープ検出スイッチ空間を有

（６）本発明は現状の一製造工程を大幅に変更すること
