ABSTRACT:
A portable camera system comprising an image sensor device for sensing an image; a processing means for processing the sensed image; a print media supply means provided for the storage of print media in a roll form; a print head for printing the sensed image on print media stored internally to the camera system; and a cutter mechanism for cutting the printed sensed images comprising a worm screw extending the length of the printed sensed image; and a worm gear attached to the worm screw and adapted to be driven the length of the printed sensed image, the worm gear including a cutting blade for cutting the print media into separate sheets. The cutting blade can comprise a rotatable wheel having a sharpened outer edge and the cogged wheel can have a series of usage indicators printed on one surface thereof and the worm gear can includes a lever arm wherein the traversal of the worm gear along the length of the printed sensed image results in the engagement of the lever arm with the cogged wheel print indicator so as to rotate the cogged wheel print indicator so that it maintains a current indication of the number of images printed out on the print media. The camera can further comprise a pawl mechanism which interacts with the coggs of the cogged wheel print indicator in the form of a rachet and pawl mechanism and the lever arm can includes a flexible portion for engagement with the cogged wheel print indicator.
