Abstract
Abstract A control device for controlling the operation of a transcribing machine so that successive transcribing intervals are overlapped by a predetermined amount to facilitate transcription. A circuit is provided for automatically causing the dictation recording medium to move a predetermined amount in a transcribing reverse direction in response to termination of recording medium movement in a transcribing forward direction. The automatic transcribing reverse movement is controlled by a capacitor charging current which occurs when the recording medium stops moving in a transcribing forward direction. The amount of overlap of successive transcribing intervals is proportional to the duration of the capacitor charging current.
