PURPOSE: A roller type pattern forming device is provided to improve optical properties by preventing the inconsistency of a pattern formed on a sheet according to the thickness difference of a stamper. CONSTITUTION: A roller type pattern forming device includes a pair of roller members on the upper and lower parts. The roller member includes an upper roller(10) and a lower roller(20). The upper roller includes a stamper transferring a pattern on a sheet. The lower roller is formed from a roller group to which a plurality of unit rollers is connected. The unit roller independently generates displacement according to the thickness difference of a sheet when the pattern transferred. |
