ることにある。[Detailed Description of the Invention] The present invention includes a head substrate that is slidably provided so that the magnetic head can approach and separate from the cassette tape, and a head substrate that is provided on the head substrate to apply tension when the cassette tape reaches the end. Regarding a cassette type tape recorder equipped with a tape end detection member for detecting an increase in tape end detection member, the purpose thereof is to prevent the tape end detection member from malfunctioning.
従来におけるこの種のカセット式テープレコーダでは、

と、テープ終端検出部材がカセットに近づきすぎて誤動
作し、テープの走行を停止させてしまうという欠点があ
った。In conventional cassette tape recorders of this type,
When moving the head board forward and locking it at the playback position, if there is a lot of play (backlash) in the forward movement of the head board, the tape end detection member will come too close to the cassette and malfunction, causing the tape to stop running. There was a drawback.
特に重載用のテープデツキに多いスライドインカ式のテ
ープレコーダでは、カセットを勢いよく本体内に挿入し
た際、テープ終端検出部材にカセットが衝撃的に当たっ
て誤動作を起こし、挿入したカセットが直ちにインジェ
クトされてしまう等の問題があった。Especially in slide-in type tape recorders, which are often found in heavy-duty tape decks, when a cassette is forcefully inserted into the main body, the cassette hits the tape end detection member, causing a malfunction, and the inserted cassette is immediately injected. There were problems such as storage.
そこで本考案はこのような従来の問題を解消しようとす
るものであり、以下にその一実施例について図面と共に
説明する。The present invention is intended to solve these conventional problems, and one embodiment thereof will be described below with reference to the drawings.

付けられたテープ終端検出レバー、１０はテープ終端検
出レバーの一端Ｉこ設けられた検出子である。In the figure, 1 is a reel-to-type tape with built-in magnetic tape 2.
A reel-type normal tape cassette 3 is equipped with a magnetic head 4 for both recording and playback, and is moved toward and away from the tape cassette 1 in the force direction of arrow AB using a shaft 5°6 embedded in the main board as a guide. 7 is a tension spring that urges the head substrate 3 in the direction of arrow A; 8 is a tape end detector rotatably attached to a shaft 9 implanted on the head substrate 3; The lever 10 is a detector provided at one end of the tape end detection lever.
この検出子１０は図示の如く再生状態で磁気テープ２に
当接し、テープが終端した時の張力増加によって押移動
される。As shown in the figure, this detector 10 comes into contact with the magnetic tape 2 in the reproducing state, and is pushed and moved by the increase in tension when the tape ends.

ている。The movement of the detector 10 causes the lever 8 to rotate in the counter-0n-r direction, and the normally closed switch 11 is turned off at the other end of the lever 8, thereby stopping power supply to, for example, a tape drive motor. It is designed to stop the tape recorder.
１２は検出子１０をテープ２に軽く接触させるための引
張ばねである。12 is a tension spring for bringing the detector 10 into light contact with the tape 2.
さら（こ上記ヘッド基板３の前端、テープカセット側に
は折曲片（テープカセット移動阻止片）１３が設けられ
ており、テープカセット１とテープ終端検出レバー８の
回動支軸９との間の距離が一定値以上小さくなるようｆ
こなされている。Furthermore, a bending piece (tape cassette movement blocking piece) 13 is provided at the front end of the head board 3 on the tape cassette side, and is arranged between the tape cassette 1 and the pivot shaft 9 of the tape end detection lever 8. so that the distance of f becomes smaller than a certain value
It is being done.
なおりセット１は傾斜しないようにガイドされている。The guide set 1 is guided so as not to tilt.
このような構成であるので、テープカセット１を接着す

当接し、テープ２によって検出子１０が過度に押される
ことはなく、レバー８の誤動作を防止することができる
。With this configuration, when adhering the tape cassette 1, even if the tape cassette 1 is bonded vigorously, the cassette 1 will not come into contact with the blocking piece 13, and the detector 10 will not be pushed excessively by the tape 2, preventing the lever 8 from malfunctioning. can be prevented.
以上説明したように本考案のカセット式テープレコーダ
によれば、ヘッド基板にカセット移動阻止片を設けると
いう至って簡単な構成で、テープ終端検出部材の誤動作
を確実に防止することができる。As explained above, according to the cassette type tape recorder of the present invention, malfunction of the tape end detection member can be reliably prevented with a very simple configuration in which a cassette movement blocking piece is provided on the head substrate.
