SOLUTION: In the power supply unit for supplying power to a drink guide apparatus being carried on the circulation carrying passage of a carrier, a primary coil being supplied from an AC power supply to generate an AC magnetic field toward the upper part of the circulation carrying passage is arranged at least at a part thereof. The drink guide apparatus mounted on the circulation carrying passage incorporates a secondary coil arranged oppositely to the primary coil and generating induction power through electromagnetic coupling with the primary coil, and a means for supplying the induction power generated from the secondary coil to the drink guide apparatus as required power.
