Lens layout block device

A lens layout block device comprising a seal feeding device that supplies an elastic seal to a seal sticking position (A). The elastic seal is loaded in a tape loading part in the form of a seal tape covered by a mount and a protective sheet and wound in a roll shape and fed by driving a motor. The protective sheet is separated by a protective sheet separating mechanism. At the seal sticking position (A), a sensor detects the leading edge of a positioning hole in the mount and stops the conveyance of the seal tape after the seal tape is fed from the detection position for a specified time. The stop position is determined as the reference sticking position of the elastic seal and a lens holder is pressed against the elastic seal from above. The mount is pulled down by the seal separating mechanism to separate the mount from the elastic seal.
