The apparatus comprises a light-tight dispenser for rolled sheet materials, such as negative stock, emulsified paper, and like photographic supplies, having nipping rollers for paying-out of the rolled materials, and a translatable blade for severing a selected length of payed-out material. The dispenser is suspensible from a vertical surface, such as a wall of a room or a panel of a camera unit (which latter may have an entry access for a severed length of the material). The dispenser has a channel which defines a rectilinear frame in which a sheet material cassette is light-sealingly nested and restrained. The cassette intimately engages the innermost portion of the channel to feed sheet material therefrom to the aforesaid nipping rollers, which are in adjacency thereto. The aforesaid frame has a given depth which assures light-sealing of the nested cassette, and the latter and the channel have camming structures cooperative, upon the cassette being inserted into the frame, to cause a sheet material-discharging, leading portion of the cassette to open slightly to facilitate pay-out of the material therewithin.
