Device for positioning an object relative to a carrier means

Claim 1

Device for positioning an object, particulary a photographic film being provided with at least one positioning mark, relative to a surface of a cylinder rotatable about an axis, comprising: a recess in said cylinder extending to said surface of said cylinder in parallel to said axis, a mounting piece displaceably arranged in said recess in parallel to said axis, a seating being arranged at one end of said recess, a displacing means for displacing said mounting piece in and along said recess, said displacing means being seated in said seating, a connecting member having two end portions, one end portion being connected to said displacing means, the other end portion being connected to said mounting piece, a first bar being resiliently connected and substantially in parallel to said mounting piece, a second bar being displaceably arranged relative to said cylinder surface and being secured to said cylinder, said first bar and said second bar being substantially in parallel to each other in spaced relation, two strips being arranged between neighboring end portions of said first and said second bar and being secured thereto, said film being tensioned between said first bar and said mounting piece and being arranged between said second bar, said two strips and said cylinder surface, drive means for rotating said cylinder about said axis of rotation, and a measuring microscope for observing and aligning said reference mark on said film relative to the optical axis of said microscope, said measuring microscope being arranged in spaced relation to said cylinder, the optical axis of said measuring microscope being substantially at right angles to the axis of rotation.
