Supporting mechanism for a movable member of linear pulse motors

In a supporting mechanism for a movable member of a linear pulse motor in which a magnetic flux is generated in a gap defined between opposing faces of a stator and a movable member so that the movable member is movable parallel to the opposing face of the stator along a linear passage, the improvement which comprises:

• (a) a pair of holding members, disposed above the stator;
• (b) a plurality of first rolling members, rotatably held in the holding members to be in rolling contact with the movable member and the stator and to form the gap, for movably supporting the movable member;
• (c) a pair of guide members, opposingly disposed on the stator across the linear passage, for defining opposite sides of the linear passage;
• and
• (d) a plurality of second rolling members, rotatably held in the holding members to be in rolling contact with the guide members and opposite lateral edges of the movable member wherein one of the guide members are provided to be movable in a direction to cross the linear passage, and wherein there is provided means for urging the one guide member toward the other.
