Abstract

PURPOSE:To minimize power consumption by supplying driving current only to the coil in such region as requiring driving power during the movement of moving member. CONSTITUTION:Rollers 3,4 installed on moving member 2 in free-rotating state are connected to a pair of straight-line guide rails 1a and 1b. A pair of magnets 5a, 5b as moving elements are fixed at the lower end of moving member 2 leaving a prearranged space. In addition, yoke 6 wound with plural coils 7 is extended in parallel with guide rails 1a and 1b inside the clearance of magnet 5a,5b. Photocoupler 8 is provided near the intermediate position of the coil 7 as detection means for the position of magnets 5a, 5b. Then shield plate 9 to shield light between luminescent and light-receiving elements on photocoupler 8, is installed on the moving member 2. Under this constitution, the turning on of coil 7 is controlled according to the positions of the magnets 5a, 5b.
