Filed: 1981-08-03
Abstract: PURPOSE:To decrease overload of a capstan and to perform stable control, by increasing a supply voltage to a motor driving a take-up reel of a video tape, when a current value to the capstan motor exceeds a specified value. CONSTITUTION:A signal from an error voltage amplifier 3 is applied to a motor driving amplifier 4 and a capstan motor 6 is rotated. When a tape tension is increased and the load of the capstan motor 6 is increased, since a current flowing to a resistor 8 is increased, a voltage across the resistor 8 is made higher. When this voltage exceeds a specified value, the voltage turns on an analog swtich 10 with an output signal of a current detector 9 to sum a voltage from a voltage generating circuit 11 and a reference voltage 12 at a voltage adder 18. Thus, the supply voltage of a take-up reel motor 16 is increased and the tension for a tape can be increased, allowing to reduce the overload of the capstan motor 6 and the keep stable control system.
