Abstract: A photographic copying machine has a copying unit which must receive a web of unexposed photosensitive web material well above the floor level. The web material is confined in cassettes which must be lifted before they reach a level in which the web material which is confined therein can be drawn into the copying unit. In order to facilitate manual manipulation of a relatively heavy and bulky cassette, the latter is provided with handless and with one part of a separable coupling which constitutes a hinge and enables the person in charge to pivot the cassette to an upright position subsequent to manual lifting approximately to the chest level. If necessary, the pivoted cassette is thereupon pushed into a chamber of the copying unit. A cassette for reception and storage of freshly exposed photosensitive web material can be manipulated in the same way.

Abstract: A copying apparatus has a receiving station, an exposure unit, a developing unit, an inspection station and a pricing unit with a memory. A master to be reproduced arrives at the receiving station together with an order for the reproduction thereof. The order has a coded order number which is read by a scanner at the receiving station and entered in the memory to establish a data set. The exposure unit is inoperative upon arrival of the master at the receiving station and is activated only upon entry of the order number. The master is then drawn into the exposure unit where copy material is exposed to light which has illuminated the master. The copy material is developed in the developing unit and the resulting copies are delivered to the inspection station where they are inspected for quality. The number of copies made is entered in the memory and incorporated in the data set with the order number.

Abstract: A band of exposed and developed photographic film is transported longitudinally along a predetermined path. The film carries a series of images and each of the images has a pair of edges which are spaced longitudinally of the band and extend transversely of the latter. Transverse, strip-shaped segments of the band are photoelectrically scanned to detect abrupt density changes associated with the edges of the images. In addition, the band is sensed at a predetermined location of its path in order to ascertain the length of the band travelling by the predetermined location. The density and length data are sent to a microprocessor which uses the data to assign a position coordinate to each detected edge and its corresponding image. The position coordinates represent the positions of the images longitudinally of the band.
