摘要： In a lens mounting mechanism, by rotating a ring member through touching lugs of the ring member and aligning grooves of a base member and recesses of the ring member in the circumferential direction, and then inserting a lens barrel into a hole portion, the lens barrel is moved to the hole portion without being interfered by projections of a barrel mounting member, so that the lens barrel can be inserted into the hole portion until a flange portion abuts against an opening end surface. Then, by touching the lugs of the ring member and rotating the ring member to displace the recesses from the grooves of the base member in the circumference direction, the projection of the barrel mounting member is locked by the ring member and the barrel mounting member is fixed to the base member, so that the lens barrel can be mounted to the apparatus body.

摘要： The present invention offers a universal guide device capable of using the sliders of conventional straight guide devices intact. The universal guide device does not need a different slider for each different radius of track rail. The universal guide device can be manufactured at lower cost than heretofore. This universal guide device in accordance with the invention comprises a track rail and sliders mounted to the rail via balls circulating through endless circular paths. The rail has at least one straight region and at least one curved region shaped in an arc with a given radius of curvature. Each of the sliders is of saddlelike cross section. The sliders span the rail. The sliders have ball-rolling surfaces shaped linearly. The curved region of the rail is set narrower than the straight region of the rail.
