ABSTRACT:
In the recorder disclosed, a recorder assembly includes playback and motor control circuits and a signal generating device generates a signal proportional to the amount of tape travel. A counter interprets the signal from the generating device and an electro-optical display arrangement with an indicator displays the value of the signal at the counter. A power source serves for energizing both the assembly and the electro-optical display equipment, while a connecting arrangement connects the electro-optical display equipment to the power source. A tape travel detection circuit detects tape travel in response to the signal generating device. A switching element controlled by the output of the tape travel circuit is located between the assembly and the connecting arrangement so as to maintain the output of the electro-optical display equipment whether or not the recorder assembly is energized.
