ABSTRACT:
A take-up chamber for receiving an elongated filmstrip having a predetermined width between the longitudinal edges thereof and an image area less than the width. The take-up chamber has a chamber housing for accommodating the filmstrip within the chamber. The housing has first and second side walls spaced apart to accommodate the width of the filmstrip, a lateral wall extending between the first and second side walls, and a slit extending through the lateral wall and between the first and second side walls through which the filmstrip may be introduced or withdrawn from the chamber. Two parallel laterally spaced generally circular guides extend the inside of said chamber from adjacent one side of the slit to the other side of the slit. Each guide has a substantially continuous inner surface, to contact only respective longitudinal edges of a filmstrip and cause the filmstrip to wind into a roll within the chamber as the filmstrip is advanced through the slit.
A scanner having using such a take-up chamber is also provided.
