ABSTRACT:
A photo film cassette has a spool about which photo film is wound. A data disk is disposed near to an axial end of a core of the spool. To record a bar code 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 supports the data disk. A slider 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 in the advanced position is adapted to lift the data disk by contact with a bottom of the data disk. A hot stamping head is pressed against a top of the data disk, and records a bar code thereto. Cushion springs are biasing the disk support up toward the hot stamping head.
