The system has a comparing unit comparing a detection signal from a current-detecting unit with a preset reference current. A current amplifier/limiter (36) limits current to be supplied to a rotary driving source (12) such that the current does not exceed the reference current, when a load is applied to the source in an energized state, and a drive shaft of the source is stopped and restricted by a movement of a slider. |
