    Abstract: THE INVENTION CONCERNS DICTATING TRANSCRIBING APPARATUS USING A MAGNETIC BELT RECORD MEDIA AND HAVING A VARIETY OF AUTOMATIC AND SEMIAUTOMATIC FEATURES. THE TRANSCRIBING UNIT HAS AN ASSOCIATED HEAD SET AND FOOT CONTROL AND IS ARRANGED FOR LOADING AND UNLOADING OF THE MAGNETIC BELT FROM THE FRONT OF THE UNIT. VARIOUS OPERATING CONTROLS ARE ALSO PROVIDED ON THE FRONT OF THE TRANSCRIBING UNIT. TRANSCRIBING OPERATIONS ARE UNDER CONTROL OF A FOOT PEDAL AND INCLUDE STARTING AND STOPPING OF THE BELT MOVEMENT, A MEASURED REVIEW WHICH IS REPEATABLE, A FORWARD REVIEW, AND OTHER OPERATIONS REQUIRED FOR TRANSCRIBING. THE UNIT FEATURES AUTOMATIC RECALL STRUCTURES AND CIRCUITS FOR RELATIVELY REPOSITIONING THE SOUND HEAD AND BELT UP TO FIVE (5) WORDS OF PRIOR DICTATION FOLLOWING RELEASE OF THE FOOT CONTROL IN A PLAYBACK OPERATION IN ORDER TO REPEAT THE WORDS WHEN STARTED AGAIN. A RACK AND TIMER COOPERATE WITH RELAY CIRCUITS TO CONTROL THE EXTENT OF RECALL.

    Abstract: The invention concerns dictation systems having facilities for selectively connecting remote stations to a central recording unit, and recognizing control tones generated at a connected remote station to effect all operations required including recording and playback of audio (voice) signals. The systems include, in several versions, circuits responsive to presence or absence of voice signals to start and stop the recording unit (respectively), an intermediate voice buffer to prevent loss of voice signals during startup time and features circuitry to insure that control tones are recognized properly, but not recorded on the media in the central recording unit.

    Abstract translation: 本发明涉及具有用于将远程站选择性地连接到中央记录单元的设备的听写系统，以及识别在连接的远程站产生的控制音调以实现所需的所有操作，包括音频（语音）信号的记录和回放。 该系统在几个版本中包括响应于存在或不存在语音信号的电路来分别启动和停止记录单元（分别），中间语音缓冲器，以防止在启动时间期间语音信号的丢失，并且具有确保控制音调的电路 正确地识别，但不记录在中央记录单元的介质上。
