PURPOSE:To make a trial run of various kinds of products efficiently by feeding a.c. supply voltage of the required frequency to a pallet transported along rails selectively from a plurality of sliding power supply buses different in frequency of power. CONSTITUTION:When a pallet 6 transported on rails 2, 2 by a conveyer 4 is stopped by a stopper 22, a short conveyer 11 rises in response to a stop signal, so that a mover 13 stopped on the conveyer 11 and the pallet 6 are electrically and mechanically connected to each other. The required frequency and voltage are selected by operating push-botton switches 18, 19. In such a condition, the stopper 22 is turned in a 90 deg. arc to a virtual line position to disengage the stopper 22 from the roller 31, so that the pallet 6 and the mover 13 are connected together and moved to the right by the conveyer 4. Thus, a.c. supply voltage of the required frequency is applied to television, video and so on on the pallet 6 through the mover 13 from the sliding power supply buses 16, 16' so as to make a test run or running in trial thereof. |
