Abstract
The invention relates to an installation for exposing a double-sided printed circuit card to light through artworks. The installation comprises a first artwork-support (10) that is fixed, a second artwork (14) that is movable, vertical displacement means (26, 28) for moving the second support, and mechanical connection means between the displacement means and the second support, the first and second supports having relative positioning members (12, 24) suitable for mutual co-operation when the two supports are in the working position. The mechanical connection means comprise a first horizontal connection surface (42, 44) mechanically connected (38, 40, 46, 48) to the vertical displacement means, a second horizontal connection surface (20, 22) secured to the second support, support means (50) for establishing substantially frictionless co-operation between the first and second connection surfaces (42, 44; 20, 22), and controllable locking means (50) for temporarily locking the first and second connection surfaces together.
