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.
