Abstract: PROBLEM TO BE SOLVED: To drive a control target irrespective of a control method whether the control target is mode-driven or command-driven, by automatically converting an instruction transmitted in a target mode into a command instruction, and sending it out to a command communication interface. SOLUTION: A mode-command converter 10 comprises a mode comparison means 16 configuring a mode-command conversion part 9 and a command generating means 17. The mode comparison means 16 compares a target mode TM1 from a mode drive generating device 11 with an operation mode AM1 from a control target 13 and sends out the comparison result CR. The command generating means 17 sends out a control command CC to the control target 13 via a command communication interface 18 based on the comparison result CR, the target mode TM1, the operation mode AM1 outputted from the command communication interface 18 via the control target 13, and a control permission signal CP.

Abstract: PURPOSE:To provide a controller for allowing quick rise of rotational speed and rotational phase of a rotator upto target levels. CONSTITUTION:A controller is started to raise the rotational speed of a rotator upto a first target speed which is different by 1/5-1/6 from a final target speed (Step ST1, 2). When the first target speed is reached, phase difference is monitored between an external reference signal corresponding to the final target speed and the rotator. When the difference comes within a predetermined range, acceleration from the first target speed to the final target speed is started (Step ST3, 4). The phase difference range is set such that the rotational phase is matched with that of the reference signal upon reaching the final target speed.

Abstract: PROBLEM TO BE SOLVED: To control fully automatically and to eliminate fear of generating human errors and the like. SOLUTION: An FG(frequency generator) 4 is provided in a capstan 2 for moving a magnetic tape 1 and a capstan motor 3. The positive and negative outputs of this FG 4 are supplied to a comparator 6 through an amplifier 5, and compared with a voltage level (a), with waveform shaping performed. In addition, with a shaped pulse signal supplied to a micro computer 7 for servo processing, a driving signal formed by this micro computer 7 is supplied to the capstan motor 3 through a driving circuit 8. Further, the arbitrary voltage level (a) formed by the micro computer 7 is supplied to the comparator 6 through a low-pass filter 9. As a result, waveform shaping is performed for the output signal from the FG 4 by this comparator 6 and also, the duty ratio of this shaped pulse signal is adjusted by arbitrarily controlling the voltage level (a) by the micro computer 7.

Abstract: PROBLEM TO BE SOLVED: To enable a sub-tape to be automatically made out when the dubbing is made for the master tape by stopping the recording operation of a recorder in accordance with the output detected by a detecting circuit when the unrecorded section of the master tape is reproduced by a reproducing device at the time of dubbing. SOLUTION: The recorder 12 is made to the recording pause state by supplying a control signal S12 to the recorder 12 from a microcomputer 13, and the reproducing device 11 is made to the reproducing state from the head of the master tape by supplying a control signal S11 to the reproducing device 11. Since the begining part of the master tape is the unrecorded section, the detected signal 22 is in the 'L' level, and the reproducing state is continued for the reproducing device 11 and also the recording pause state is continued for the recorder 12. When the reproduction of the reproducing device 11 is progressed to the leader of the recorded section of master tape, the recorder 12 is transferred to the recording state by the control signal S12 as the result that a video signal SPB is reproduced to become S22='H', then the dubbing for the recorded section of the master tape is progressed from the head of the sub-tape.

Abstract: PURPOSE:To surely shorten the time elapsed until a rotary drum reaches a steady operation. CONSTITUTION:The synchronous state of a video signal is detected by a synchronous-state detection part 16. When it is detected by the synchronous-state detection part 16 that the state is externally synchronous, the rotational speed of a rotary drum 1 is set at the speed of an output (the signal of a first target speed) from a speed-reference-signal generation part 12. When the rotary drum 1 reaches the first target speed, the rotary drum 1 is accelerated so as to become a final target speed. In addition, the phase of the rotary drum 1 synchronized with a synchronizing signal which is output from a synchronizing-signal generation part 14. On the other hand, when it is detected by the synchronous- state detection part 16 that the state is internally synchronous, a trigger pulse which is output from a reset-trigger generation part 19 is supplied to a phase- difference-signal generation part 13. Thereby, a phase reference signal as an output from the phase-reference-signal generation part 13 is reset, and the phase of the phase reference signal is adjusted to the phase of the rotary drum 1.

CONSTITUTION:PG, FG signals of the drum 100 are outputted from detection circuits 1, 2, and the error amounts are detected by error detection circuits 3, 4, and after the outputs of gain adjusters 5, 6 are added by an adder 7 to be supplied to an amplifier 8 and a motor driver 9, and a voltage applied to the drum 100 is controlled. In this device, a phase error is formed by comparing a synchronizing signal from a phase reference generator 10 with the PG signal, and a speed error signal is formed by comparing a reference signal from a speed reference generator 11 with the FG signal. Further, a reset means 12 for the synchronizing signal from the phase reference generator 10 is provided, and the signal from the error detection circuit 4 is supplied to an operation circuit 200 of a speed and acceleration, and the reset means 12 is driven by the output of the circuit 200.
