Abstract
A laser beam emitted from a laser diode of each of detectors is applied to a partly cut region of a photosensitive sheet film which is spread toward the detectors by a film bending roller. Part of the laser beam which is reflected from the partly cut region is detected by an amount-of-light sensor. The laser beam that is applied to a surface of the photosensitive sheet film other than the partly cut region is reflected outside of a light-detecting area of the amount-of light sensor, and is not detected by the amount-of-light sensor.
Claims20
A detecting device which detects a recess purposely formed in a sheet body which defines a peeled laminate region of said sheet body exposed to be boned with a substrate, comprising:
- spreading means which deforms said sheet body to spread said recess;
- illuminating means which applies illuminating light to said sheet body with said recess being spread by said spreading means;
- and
- light-detecting means which detects said illuminating light reflected by said sheet body;
- wherein said recess is detected based on said illuminating light detected by said light-detecting means.
An apparatus for manufacturing a laminated body by forming a recess in a predetermined area of a sheet body having a plurality of laminated sheet layers, supplying said sheet body to a substrate, and laminating said sheet body onto said substrate based on said recess, comprising:
- a detecting unit which detects said recess;
- and
- a laminating unit disposed downstream of said detecting unit, which laminates said sheet body onto said substrate;
- said detecting unit comprising:
- spreading means which deforms said sheet body to spread said recess;
- illuminating means which applies illuminating light to said sheet body with said recess being spread by said spreading means;
- and
- light-detecting means which detects said illuminating light reflected by said sheet body;
- wherein said recess is detected based on said illuminating light detected by said light-detecting means.
