Abstract: A dye ribbon package for use with a thermal printer and containing for that purpose in spaced parallel relation therein a supply spool wound with dye ribbon and a take up spool for rewinding the dye ribbon as it is unwound from the supply package, a leading end of the dye ribbon on the supply spool being attached to the take up spool, each spool having a winding core with a free end portion, in which the package has a bottom wall and at each of the opposite sides of the bottom wall normal to the spool axes upstanding lateral wall integral with the bottom wall. Each lateral wall has two laterally spaced apart panels, both cut out downwardly from their edges opposite the bottom wall to removably receive the free end portions of the spool cores and permit free access to the end faces of the spool cores.

Abstract: A daylight reloadable lighttight plastic cassette for holding and dispensing a roll of light sensitive material is formed of a hollow open-ended tubular housing having lighttightly mating hingedly connected base and lid sections which pivot apart on the hinge to open the housing, A dispensing slot lighttightly sealed, e.g. by plush fabric, is present on the housing side opposite the hinge, preferably defined between suitably spaced longitudinal edges of the housing sections. The opposite housing ends are lighttightly closed by end caps, each molded in two mating sections, which are telescopingly fitted on end margins of the housing sections. The end cap sections can be carried by the respective housing sections to pivot therewith in clam-shell fashion. The housing sections can be latched in closed position, preferably with latches engaging the end cap sections.
