Abstract

This invention provides for a print roll cartridge for a camera system. The cartridge includes a cylindrical internal core portion having a former dividing said core into a plurality of longitudinal ink supply reservoirs. The former also locates a paper supply roll thereon. The cartridge includes a covering unit which defines a slot and which houses the core portion, as well as a roller assembly attached to the covering unit to feed paper from the supply roll through the slot to the camera system.

Claims

1. A print roll cartridge for a camera system, said cartridge comprising:

a cylindrical internal core portion having a former dividing said core into a plurality of longitudinal ink supply reservoirs, the former locating a paper supply roll thereon;

a covering unit which defines a slot and which houses the core portion; and

a roller assembly attached to the covering unit to feed paper from the supply roll through the slot to the camera system.

2. The cartridge of claim 1, wherein the internal core portion terminates in a sealing cap having apertures in fluid communication with the respective supply reservoirs.

3. The cartridge of claim 2, wherein the covering unit defines an aperture for receiving a pronged adapter so that the respective reservoirs can be brought into fluid communication with a printer of the camera system.

4. The cartridge of claim 1, wherein the supply reservoirs each include hydrophobically treated sponge portions for suspending ink therein.

5. The cartridge of claim 1, wherein the roller assembly includes two pinch rollers and a drive roller, the pinch roller to pinch the paper against the drive roller to provide for a de-curling of the paper around the core portion when the paper is fed to the camera system.

6. The cartridge of claim 1, wherein the covering unit includes an end protuberance to align the slot with a printing platen structure within the camera system.

7. The cartridge of claim 1, wherein the core portion includes a series of air breathing channels sealed by hydrophobically treated sealing tape which is placed over an end of the core portion to inhibit the entry of any fluid into such air breathing channels.

8. The cartridge of claim 1, wherein the core portion includes a series of ribs on an outer surface thereof to allow for minimal frictional contact between the core portion and the paper.
