Claims

[Scope of utility model registration request]

A plurality of magnetostrictive delay lines provided according to control items, a plurality of drive coils that drive each magnetostrictive delay line, means for periodically applying a drive pulse to each drive coil, and a magnetostrictive device that advances each magnetostrictive delay line. a detection coil that selectively detects vibration; a detection means that detects the selected magnetostrictive delay line; and a counter circuit that is reset at a predetermined period and stops counting based on the detection pulse obtained from the detection coil. A control device characterized in that the control device is characterized in that it obtains a control signal based on the count value of the counter circuit.
