Abstract
A support for an optical device such as an optical read head, permits the optical device to be positionable along a linear path. The support includes a precision bar and two gibs, with first and second adjustable means for securing the gibs to one another and slideably to the bar.
Claims21
Linearly positionable apparatus, comprising in combination:
- a bar having a longitudinal dimension, first and second flat side surfaces extending along said longitudinal dimension, and first and second edge surfaces extending along said longitudinal dimension between said first and second side surfaces;
- and
- a clamping device including
- a first clamp member having a channel for receiving a portion of said bar including a portion of said first edge surface,
- a second clamp member having a channel for receiving a portion of said bar including a portion of said second edge surface,
- first adjustable means for securing said clamp members to one another with said bar being retained by said channels and for controlling the drag force between said clamp members and said edge surfaces when said bar is retained by said secured clamp members and said secured clamp members are slideably urged longitudinally along said bar, and
- second adjustable means carried by said clamp members and said side surfaces for controlling the drag force between said clamp members and said side surfaces when said bar is retained by said secured clamp members and said secured clamp members are slideably urged longitudinally along said bar,
- said first adjustable means being adjustable to secure said clamp members to one another with said bar retained by said channels independently of adjustment of said second adjustable means, and said first adjustable means and said second adjustable means being adjustable independently of one another for separately controlling the drag forces respectively controlled thereby.
