Hot stamping method and apparatus for photo film spool

摘要

A photo film cassette has a spool (13) about which photo film (14) is wound. A data disk (27) is disposed near to an axial end of a core of the spool. To record a bar code (28) on the data disk in manufacturing the photo film cassette, a hot stamping apparatus includes at least one spool holder for holding the spool in a slidable manner while the core is erect and the data disk is oriented upwards. A disk support (73,74,75) supports the data disk (26). A slider (66) shifts the disk support between a retracted position away from the spool holder and an advanced position close to the spool holder. The disk support (73,74,75) has the advanced position to lift the data disk in contact with a bottom of the data disk. A hot stamping head (58) is pressed against a top of the data disk, and records a bar code thereto. Cushion springs (76,77,78) are biasing the disk support up toward the hot stamping head.
