極性反転リレー４、切替スイッチ５，６、電源端子７、
ダイオード８，９よりなっている。FIG. 1 shows the configuration of a conventional fast forward/rewind device for a general cassette tape recorder, including a fast forward/rewind motor 1, a fast forward switch 2, a rewind switch 3, a motor polarity reversal relay 4, Selector switches 5, 6, power terminal 7,
It consists of diodes 8 and 9.
そして、速送りを行なう場合は、速送りスイッチ２を閉

５を通してモータ１に供給し、モータ１を順方向に高速
回転させる。When performing fast feed, the fast feed switch 2 is closed, the power supply voltage from the terminal 7 is supplied to the motor 1 through the diode 8 and the switch 5, and the motor 1 is rotated at high speed in the forward direction.
また、巻戻しを行なう場合は、巻戻しスイッチ３を閉じ
て、極性反転リレー４を動作させて切替スイッチ５，６
を図とは反対方向に切替えて、端子７からの電源電圧を
ダイオード９、スイッチ６を通してモータ１に供給し、
モータ１を逆方向に高速回転させる。When rewinding, close the rewind switch 3, operate the polarity reversal relay 4, and switch the changeover switches 5 and 6.
is switched in the opposite direction to that shown in the figure, and the power supply voltage from terminal 7 is supplied to motor 1 through diode 9 and switch 6.
Motor 1 is rotated at high speed in the opposite direction.
ところで、オートリバース式カセットテープレコーダで
は、速送り・巻戻し操作というのは、順方向と逆方向駆
動時では、その機能が逆になってしまうので、速送り・
巻戻しという言葉は意味がなくなってしまう。By the way, in an auto-reverse type cassette tape recorder, the functions of fast forward and rewind operations are reversed when driving in the forward and reverse directions.
The word "rewind" has lost its meaning.
そのために、第１図の装置をオートリバース式カセット
テープレコーダに適用した場合、順方向か逆方向かの判
断をし、逆方向の場合は、速送りおよび巻戻しをそれぞ
れ逆に解釈して操作しなければならず、操作が面倒であ
るばかりか、操作誤りを起す可能性があった。For this purpose, when the device shown in Figure 1 is applied to an auto-reverse type cassette tape recorder, it is necessary to judge whether the direction is forward or reverse, and if it is the reverse direction, fast forward and rewind are interpreted and operated in reverse. Not only is the operation cumbersome, but there is also the possibility of operational errors.
本考案は、このような欠点を除去するために、順方向、
逆方向に応じて切替えられるスイッチを設け、順方向、
逆方向に応じてモータの極性を切替えられるようにした
速送り・巻戻し装置を提供するものである。In order to eliminate such drawbacks, the present invention aims to
A switch is provided that can be switched depending on the reverse direction, and
A fast forwarding/rewinding device is provided in which the polarity of a motor can be switched depending on the reverse direction.
第２図は本考案による速送り・巻戻し装置の一実施例の
回路図で、順方向および逆方向駆動に応じて切替えられ
る切替スイッチ１０が設けられ、それが、モータ極性反
転リレー４と速送り・巻戻しスイッチ２，３との間に接
続されている。FIG. 2 is a circuit diagram of an embodiment of the fast forwarding/rewinding device according to the present invention, in which a changeover switch 10 is provided which can be switched according to the forward direction and reverse direction driving, and it is connected to the motor polarity reversing relay 4 and the fast forwarding/rewinding device. It is connected between the forward/rewind switches 2 and 3.
すなわち、順方向駆動時には図のように巻戻しスイッチ
３が切替スイッチ１０を介して極性反転リレー４に接続
され、逆方向駆動時には速送りスイッチ２が切替スイッ
チ１０を介して極性反転リレー４に接続されるようにな
っている。That is, when driving in the forward direction, the rewind switch 3 is connected to the polarity reversal relay 4 via the changeover switch 10 as shown in the figure, and when driving in the reverse direction, the fast forward switch 2 is connected to the polarity reversal relay 4 through the changeover switch 10. It is supposed to be done.
このような構成において、順方向駆動時における速送り
・巻戻し操作は、巻戻しスイッチ３がモータ極性反転リ
レー４に接続されていることから第１図の動作と同じで
ある。In such a configuration, the fast forwarding/rewinding operation during forward direction driving is the same as the operation shown in FIG. 1 because the rewinding switch 3 is connected to the motor polarity reversing relay 4.
一方、逆方向駆動時に速送りを行なうために速送りスイ
ッチ２を閉じると、電源電圧が極性反転リレー４に供給
され、切替スイッチ５，６が図と逆方向に切替えられ、
電源電圧がダイオード８、切替スイッチ６を介してモー
タ１に供給され、モータ１が逆方向に高速回転する。On the other hand, when the fast feed switch 2 is closed to perform fast feed during reverse direction driving, the power supply voltage is supplied to the polarity reversal relay 4, and the changeover switches 5 and 6 are switched in the opposite direction to that shown in the figure.
Power supply voltage is supplied to the motor 1 via the diode 8 and the changeover switch 6, and the motor 1 rotates at high speed in the opposite direction.
また、逆方向駆動時に巻戻しを行なうために巻戻しスイ
ッチ３を閉じると、電源電圧はダイオード９、スイッチ
５を介してモータ１に供給され、モータ１は順方向に高
速回転する。Further, when the rewind switch 3 is closed to perform rewinding during reverse direction driving, the power supply voltage is supplied to the motor 1 via the diode 9 and the switch 5, and the motor 1 rotates at high speed in the forward direction.
したがって、順方向および逆方向駆動に応じた速送り・
巻戻しが可能となる。Therefore, rapid feed and
Rewinding becomes possible.
