このように構成されたテープレコーダ１は例えば録音操
作中テープカセットｃの供給側リールに磁気テープがな
くなると、テープが終端に達した事を使用者に知らせる
ために警報音などを発する事ができるものである。The tape recorder 1 configured in this manner can, for example, emit an alarm when the supply reel of the tape cassette c runs out of magnetic tape during a recording operation to notify the user that the tape has reached its end. It is something.
ｆｆＤちテープ力セントｃを装填した状態で録音操作釦
を操作すると操作レバー１５が上方に移動し、操作レバ
ー１５による誤動作防止片１４のロックを解除する。When the recording operation button is operated with ffD and tape force cent c loaded, the operation lever 15 moves upward, and the lock of the malfunction prevention piece 14 by the operation lever 15 is released.
このためテープ終端検出レバー１０は回動可能とｔよる
がバネ１６により反時計方向に偏寄されているので終端
検出作動は行わない。Therefore, although the tape end detection lever 10 is rotatable, it is biased counterclockwise by the spring 16 and therefore does not perform the end detection operation.
しかして供給側のテープが終端に達するとテープの張力
が急激に供給軸８に加わるので、この軸８を固着してい
るテープ終端検出レバー１０はバネ１６に抗して時計方
向に回動する。When the tape on the supply side reaches its end, the tension of the tape is suddenly applied to the supply shaft 8, so the tape end detection lever 10, which is fixed to the shaft 8, rotates clockwise against the force of the spring 16. .
このため検出レバー１０の先端部分に連結ピン１８を介
して連結された検出スイッチ１２が反時計方向に回動さ
れ検出スイッチ１２に設げである摺接子１９がフライホ
イール１１の内周面に当接する。Therefore, the detection switch 12 connected to the tip of the detection lever 10 via the connecting pin 18 is rotated counterclockwise, and the sliding contact 19 provided on the detection switch 12 is brought into contact with the inner peripheral surface of the flywheel 11. come into contact with

まま切欠部２１に入って終端報知作用をなすものである
が、通常はテープが終端に達し、供給軸８が時計方向に
回動した後、フライホイール１１の一回転以内でテープ
の終端報知を行うものである。In this case, when the sliding contact 19 is about to come into contact with the tip, that is, the lowest part, of the notch 21 provided in the flywheel 11, it enters the notch 21 and performs the termination notification function, but normally, the tape does not reach the end. After the supply shaft 8 rotates clockwise, the end of the tape is notified within one revolution of the flywheel 11.
即ちテース終端検出レバー１０の回動に伴って摺接子１
９がフライホイール１１の内周面に押圧されたままの状
態となるが、フライホイール１１やその他の駆動系はい
ぜんとして作動状態にある。That is, as the tooth end detection lever 10 rotates, the sliding contact 1
9 remains pressed against the inner peripheral surface of the flywheel 11, but the flywheel 11 and other drive systems are still in operation.
このためフライホイール１１は摺接子１９を当接させた
ままの状態で回転し、上記切欠部２１が摺接子１９の位
置までくると、摺接子１９はテープテンションによる棒
出レバー１０の回動力により押圧されているので直ちに
切欠部２１の最低部分に入り込む。Therefore, the flywheel 11 rotates with the sliding contact 19 in contact with it, and when the notch 21 reaches the position of the sliding contact 19, the sliding contact 19 is moved by the tape tension to the protruding lever 10. Since it is pressed by the rotating force, it immediately enters the lowest part of the notch 21.
上記摺接子１９が切欠部２１内に入った後もフライホイ
ール１１は回り続けるので摺接子１９は切欠部２１の傾
斜に沿って押し上げられ所定の位置で動作部材１２ｃを
接点部材１２ｂに当接させ、検出スイッチ１２をオンさ
せる。Since the flywheel 11 continues to rotate even after the sliding contact 19 enters the notch 21, the sliding contact 19 is pushed up along the slope of the notch 21, and the operating member 12c is brought into contact with the contact member 12b at a predetermined position. and turn on the detection switch 12.
図示しないが、この検出スイッチ１２は電源と報知装置
との間にあり、検出スイッチ１２がオンすることにより
発振器等を作動させて、スピーカ４から警報音を発する
ようになっている。Although not shown, the detection switch 12 is located between the power source and the notification device, and when the detection switch 12 is turned on, an oscillator or the like is activated to emit an alarm sound from the speaker 4.
このようにして摺接子１９がフライホイール１１の切欠
部２１に入って終端警報用のスイッチ１２を作動させた
状態になると、その抑圧作動状態はフライホイール１１
の突出平面で継続されるので報知音は連続的になり使用
者に容易にテープ終端を知らしめる事ができるものであ
る。In this way, when the sliding contact 19 enters the notch 21 of the flywheel 11 and the termination alarm switch 12 is activated, the suppressing operation state is set to the flywheel 11.
Since the notification sound continues on the protruding plane, the notification sound becomes continuous and the user can easily be informed of the end of the tape.
なお報知音を継続的に発したい場合には摺接子が必ず切
欠部から外れ、次の一回転で再び切欠部の最低部に入り
、その最高部で外れるようにしておけば検出スイッチが
オン−オフ動作を繰り返すので報知音は断続的となる。If you want to emit the notification sound continuously, make sure that the sliding contact comes off the notch, enters the lowest part of the notch again in the next rotation, and comes off at the highest part, then the detection switch will turn on. -The notification sound becomes intermittent as the off operation is repeated.
上記の如く、テープが終端に達した事を知った使用者は
ストップの操作釦を操作する事によりテープレコーダの
全ての機能を停止させる事ができる。As mentioned above, the user who knows that the tape has reached its end can stop all functions of the tape recorder by operating the stop operation button.
この場合、操作レバー１５が再び誤動作防止片１４に当
接し、検出レバーの回動を阻止しているので振動による
誤動作や、早送り、巻戻し等のテープ送り操作時にあっ
てもテープ終端検出機構は何ら作動するものではない。In this case, the operating lever 15 comes into contact with the malfunction prevention piece 14 again and prevents rotation of the detection lever, so even if malfunction occurs due to vibration or during tape feeding operations such as fast forwarding or rewinding, the tape end detection mechanism will not work. It doesn't work at all.
