Abstract: A stereopticon lantern (2) is fitted to one per se known color photocopying machine (1) operating by utilizing a photochemical process, so as the diapositive is projected onto the same reproduction screen (15) thereof, thus obtaining a double possibility of reproduction. The color photocopying machine (1) to which said stereopticon lantern (2) can be fitted comprises a horizontal shooting plane (11) constituted by a thoroughly transparent glass plate onto which the image to be reproduced is put, which image is illuminated below by adequate lamps (12) and the so illuminated image is horizontally reflected by a mirror (13) disposed at a 45.degree. angle inclined beneath said shooting plane and is projected, through a relative optical control unit (14), onto a vertical screen (15) constituted by a photosensitive paper sheet (16), obtained from a band wound about a respective roller (17).
Abstract: A film accumulating device for a film developing machine of an industrial kind in which the films are entrained by leaders. The collecting unit is situated at the outlet side of the developing machine and includes a box-like envelope (9), a series of pairs of rollers (19, 20) supported in the envelope which drive the leaders and the subsequent films connected thereto toward a subsequent roller (32). Two lateral guide supports (33, 34) deflect the leaders upwardly into guide slots (16) of lateral forks (10, 11), which are substantially extended from the end portion of the box-like envelope (9). When the leaders are completely disengaged from the roller (32) and the relative lateral guide supports (33, 34) they fall into recesses (17, 18) provided at the lower ends of the lateral forks (10, 11) and the trailing ends of the leaders are laterally supported by such recesses (17, 18).
Abstract: A machine for treating photosensitive material in the form of disc films including an enclosure having a series of treating tanks for conducting treatments of disc films, a rotatable support for holding at least one disc film and a support rotatably supporting the rotatable support. A mechanism is provided for moving the support and for placing a disc film held on the rotatable support into solutions contained in the treating tanks. The disc film held on the rotatable support SR is rotated when placed in the treating solutions contained in the treating tanks by the action of a fluid jet against blades on the rotatable support. A first member supported in the enclosure is movable up and down in a vertical direction to respectively remove a disc film from and place a disc film in one of the treating tanks. A groove in the first member slidably engages the support so that the support can move in a longitudinal direction with respect to the first member.
Abstract: Device for transferring the film holders in a film developer which was described by the Italian patent application No. 45731 A/82 of the same Applicant. Such a device is constituted by an arm (1) formed by two rods, a first fixed rod (2) which is applied in the same manner and is actuated by the same means provided to actuate the transferring arm of the above film developer, and a second movable rod (3) which is longitudinally slidable with respect to said fixed rod (2) and may assume two operating positions, a first position in which all the fork elements (21-31) which are arranged on both rods are equally spaced each other, so as to be able to catch a respective film holder (7) and to transfer it for each time in which said arm (1) is actuated.
Abstract: An apparatus for connecting a strip of photographic paper to a flat conveyor belt includes an elongated member having at a first end thereof a hook for fitting over one edge of the flat conveyor belt. The elongated member has a supporting portion spaced from the hook and adapted to have attached thereto a strip of photographic material. A slide member is mounted for longitudinal sliding movement along a portion of the length of the elongated member between the hook and the supporting portion thereof. The slide member has projecting therefrom an integral inclined tab for engaging the other edge of the flat conveyor belt. A toggle and spring structure constantly urge the slide member toward the hook, thereby ensuring that opposite edges of the conveyor belt continuously are clamped between the hook and the tab.
