Abstract
PURPOSE: To control a tape speed and tension securely and easily even in high-speed tape running state by detecting the driving current of a take-up reel motor and by controlling the servo circuit of a supply reel motor by the output of the detection.
CONSTITUTION: As the driving current of reel motor 1 varies with the load of the tape path system, the voltage across resistor 6 that detects the driving current of reel motor 1 varies and is compared to a reference voltage by voltage comparator 8, etc. Voltage comparator 8 decreases in output level when the detected voltage is greater than the reference voltage and increases when not. Therefore, as fluctuations of the load increase the driving current of reel motor 1, its rotating force also increases, but the back tension of reel motor 2 decreases to the contrary. Thus, constant rotating force torque is held and the constant speed of the take-up reel turntable can be attained. This constitution can exercise control over the tape speed and tension easily and securely even in high-speed tape run mode.
