A scanner is operative with an imaging system for inducing a mechanical movement of a subject during an optical scanning of the subject to provide an image of the subject. The subject which is in the shape of a card is advanced along a travel path past an optical viewing site by means of a drum, the scanner including a first roller and a second roller which urge the subject against the drum. Initially, the first roller is located between the viewing site and the entry port for receipt of the subject in a first nip between the first roller and the drum. The second roller is positioned fixed on the opposite side of the viewing site. The first roller is supported by an arm which swings about a rotational axis of the drum to vary the spacing between the two rollers. Upon rotation of the drum in a forward direction for induction of the subject, a brake located between the drum and the arm drags the arm and the first roller towards the second roller to facilitate a transference of a leading edge of the subject from the first nip to a second nip defined by the second roller and the drum. Preparatory to optical scanning of the subject which is accomplished during reverse rotation of the drum, the arm swings the first roller away from the second roller to present the viewing site to the optical scanning beam.

A chair which is fixed in a single location yet which may be selectively positioned to face any direction includes a seat member, a back member, and two or three legs, a first leg of which is structured to provide an approximately vertical pivot axis disposed at the rear of the chair midway between its sides. A cross member secured perpendicular to the first leg proximate the upper edge of the seat back defines a horizontal axis about which the chair can be pivoted. Arm rests provide grip means disposed toward the front of the chair at a position which gives the user a mechanical advantage so as to easily effect simultaneous pivotal movement about the horizontal and vertical pivot axes. Lightweight in construction, the chair can be readily positioned by the user in any desired direction with an easily executed movement.

A unitary frame for mounting a film transparency having leading and trailing ends and spaced parallel sides which surround a picture area. The frame includes first and second members which are adapted for movement between a film transparency loading position and an operative position wherein they enclose and support the transparency. The frame includes, in the transparency loading position, a pair of laterally spaced open-ended guides for slidably receiving the parallel sides of the transparency as it is advanced into its proper relationship relative to the frame, and a pair of surfaces which extend forwardly of the open end of each of the guides and which function to direct the leading end of the transparency into the open end of each of the guides.

Frame for transparency film

A manually operable, compact apparatus for sequentially cutting sections of film, each of which includes a visible photographic image and mounting the same in a frame for subsequent use in a projector or viewer. The apparatus is specifically adapted for use with frames of the type which have a pair of open-ended guides for receiving the film. The apparatus includes structure for supporting the frame at an acute angle relative to a plane containing the path of movement of an advancing section of film. By so inclining the frame relative to the path of movement of the film, the leading edge of the advancing film is deflected by a portion of the frame in a predetermined direction and along a well-defined path into the open end of each of the two film guides. The apparatus also includes means for maintaining a trailing edge portion of the section of film to be mounted in a generally horizontal plane during the deflection of the film's leading edge. Accordingly, after the leading edge of the film bottoms out at the closed end of each guide, and the trailing edge is severed from the remainder of the roll of film, the trailing edge moves in a direction to relieve the stresses in the severed section caused by the deflection of the leading edge of the film. This latter movement results in the trailing edge of the severed section being automatically located in operative relation with the aforementioned frame portion.

Apparatus for mounting transparency film

A photographic film assemblage including an elongate composite film structure of the self-developing or instant type for use in conventional still type cameras of the non-self-developing or non-instant type. The composite film structure includes first and second sheets which are coiled within a cylindrical cassette such that only the first sheet is uncoiled and photographically exposed within such camera. A rupturable container of processing liquid is carried by one of the sheets. After the first sheet has been exposed, it is recoiled into the cassette and the latter is then removed from the camera and placed in a processor. The processor removes the first and second sheets from the cassette in a sequence which eventually locates the second sheet in engagement with the first sheet such that the former functions to aid the spreading of the processing liquid between the two sheets as they move between a pair of rollers to initiate the formation of a visible image within the composite film structure.

Photographic film assemblage

A compact, manually operable apparatus for sequentially cutting sections of an elongate strip of photographic film containing a plurality of distinct, individual exposures or images and mounting the same in individual frames for subsequent viewing, e.g. in a slide projector. The apparatus includes structure for folding an apertured portion of a frame onto another apertured portion of the frame so as to enclose a section of the film therebetween as the frame is being moved toward a station whereat the two frame portions are fixedly secured to each other.
