OPTICAL FILM CUTTING DEVICE, METHOD FOR CUTTING OPTICAL FILM AND RECORDING MEDIUM

摘要

An optical film cutting device is provided with: a transfer unit for transferring a belt-like optical film from a first position to a second position; an imaging unit for imaging a third position on the transfer track for the optical film; a control unit which transfers the optical film with the transfer unit by a first transfer amount from the first position toward the second position, images the optical film with the imaging unit, calculates a second transfer amount on the basis of the second position and the position of the optical film imaged by the imaging unit, and further transfers the optical film toward the second position with the transfer unit by the second transfer amount; and a first cutting unit for cutting the optical film transferred by the transfer unit by the first and second transfer amounts at a fourth position on the transfer track.
