Claim Text:
1. An exposure apparatus for causing an exposure pattern formation region of a member to be exposed continuously conveyed by a conveying apparatus to be irradiated, via masks, with an exposure light emitted from an exposure light source, whereby said exposure pattern formation region is exposed to a mask pattern corresponding to each of said masks, the exposure apparatus comprising: a first mark-forming unit for forming a meandering-detection mark on said member to be exposed, the first mark-forming unit being arranged further upstream than an irradiation position for said exposure light in a direction of movement of said member to be exposed; a first detection unit for detecting a position of said meandering-detection mark in a direction intersecting the direction of movement of said member to be exposed, the first detection unit being arranged between said first mark-forming unit and the irradiation position for said exposure light in the direction of movement of said member to be exposed; a first meandering computation unit for computing an amount of meandering by said meandering-detection mark on the basis of the position of said meandering-detection mark as detected by the first detection unit; a second mark-forming unit for forming an alignment mark for adjusting a position of said masks, the second mark-forming unit being arranged so as to be capable of moving in a direction perpendicular to the direction of movement of said member to be exposed, at a position corresponding to a position of said first detection unit in the direction of movement of said member to be exposed; and a first control unit for moving said second mark-forming unit so as to negate the amount of meandering by said meandering-detection mark as found by said first meandering computation unit.
