Abstract

A driver (18) comprises a direction-switching means (34) which switches a rotation direction of a rotary driving source (12) based on a direction instruction signal, a current amplifier/limiter (36) which converts a voltage outputted from the direction-switching means (34) into a corresponding current and which limits the current to a preset reference current IMAX (threshold value), a current sensor (38) which detects the current supplied to the rotary driving source (12), and a current loop (40) which feeds back a detection signal supplied from the current sensor (38) to an upstream side of the current amplifier/limiter (36).
