    • Apparatus is provided for switching between recording and playback modes of a tape recorder having a single input/output jack to which an output plug for an earphone, a headphone or the like, or an input plug for a microphone or the like can be connected. The jack is compatible with two channels. When a remote-control unit having a remote-control switch and connected to an input/output transducer is connected to the jack, one channel is used as an input channel for a remote-control signal, and the other channel is used as an input/output channel for an audio signal. In another embodiment, the tape recorder has a control circuit for discriminating between insertion of a 1-channel plug and insertion of a 2-channel plug into the 2-channel jack to control the operation of switches included in this tape recorder.
    • 提供了用于在具有单个输入/输出插孔的磁带录音机的记录和重放模式之间进行切换的装置,用于耳机,耳机等的输出插头或用于麦克风等的输入插头可以连接到该记录和重放模式。 插孔与两个通道兼容。 当具有遥控开关并连接到输入/输出换能器的遥控单元连接到插孔时,一个通道用作遥控信号的输入通道,另一个通道用作输入 /音频信号的输出通道。 在另一个实施例中,磁带录音机具有一个控制电路,用于区分1声道插头的插入和2声道插头插入到2声道插孔中,以控制包含在该磁带录音机中的开关的操作。

    • In a recording medium playback device, such as a tape recorder, the playback speed is changed from the speed used during recording but the sounds and voices being reproduced can be listened to at the normal pitch, as if the playback tape speed was the same as the recording speed. A frequency generator (FG) system is not required and the playback signal is converted in pitch based on a capstan motor drive signal that is converted to a voltage value and that controls a pitch converting circuit. Alternatively, the pitch converting circuit is controlled by a signal derived from a speed control system, whereby the capstan motor speed is controlled by the user of the tape recorder. By converting the pitch of the playback signal in this way a recording of a conference, for example, can be scanned at high speed yet the reproduced voices are provided with a normal pitch.
    • 在诸如磁带录音机之类的记录介质重放设备中,重放速度从记录期间使用的速度改变,但是可以以正常音调来聆听正在再现的声音和声音,就好像重放磁带速度与 录音速度。 不需要频率发生器(FG)系统,并且基于被转换为电压值并且控制音调转换电路的主导轴电动机驱动信号来转换播放信号。 或者,音调转换电路由来自速度控制系统的信号控制,由此主导轴电动机速度由磁带录音机的用户控制。 通过以这种方式转换播放信号的音调,例如可以高速扫描会议的记录,而再现的声音被提供有正常的音调。
