A cassette, particularly for a printing mechanism provided with a thermal printing head, with a ribbon reel and a ribbon take-up reel, includes a housing composed of two wall portions which are spaced apart from each other, wherein the wall portions have grooves, integrally formed indentations or slots, wherein outer portions of the ribbon reel or take-up reel are supported in the grooves or indentations or slots so as to be slidable essentially transversely of the axis of the respective reel.

A cassette in which a radiographic image converting plate is accommodated, comprises a case having an opening; a tray on which the radiographic image converting plate is loaded; and a cap capable of being fitted with the opening, the cap connected with the tray so that the tray is moved together with the cap so as to be inserted into or drawn out from the case through the opening, the position of the cap capable of being displaced relative to the tray.

A cassette comprises a movable member supported on a box member for movement in a direction normal to an swing axis, around which a cover member swings, and an engaging claw combined with the movable member. The movable member is urged to one side of the direction along which the movable member moves. A stopper secured to the box member receives the urged movable member and holds it at a locking position. An engaged claw, which is mounted on the cover member, is engaged with the engaging claw of...

A cassette for use in an apparatus for the recording and/or playback of recording on or from a strip-shaped record carrier, which cassette contains a take-up core and a supply core for the record carrier and a single, flanged, freely rotatable, and displaceable, guide roller which is mounted so as to be floating and engages the outer circumferences of the record carrier rolls wound on the supply and take-up cores. The flanges of the roller simultaneously guides the outer turns of both record car...

This invention relates to a cassette for taking and identifying X-ray radiographs comprising means defining an access slot in the cassette, a film identification chamber in a portion of the cassette communicating with said slot, electroluminescent means in said chamber capable of emitting visible light upon electrical excitation, and means to provide electrical connection between the electroluminescent means and means for supplying electrical excitation.

A cassette having a rectangular body made from plastic material including a marginal frame bounding a pair of film compartments separated by a radiation barrier and opening outwardly through opposite faces thereof. A pair of covers also made from plastic material and hingedly connected to opposite ends of the frame provide closures for the two film compartments. Each cover has a peripheral bead which is received within an associated groove in the frame when the cover is in a closed position. A U...

A film cassette for daylight handling of X-ray film. The cassette includes a flat, thin profiled housing with an opening along one edge through which film sheets may be inserted and removed. Internally of the housing are opposed intensifying screens, one of which is movable away from the other to permit insertion and removal of the X-ray film sheets. A plate member having a lifting mechanism cooperates with the movable intensifying screen to urge it against the other intensifying screen when a f...

A cassette and associated spool for film, sound track and like material, with means for supporting the outer areas of the spool flanges to prevent sagging and warping of the spool flanges. The support means comprises interengaging formations on the cassette and on the spool. The interengaging formations may include projections on one of the cassette and the spool and recesses on the other of the cassette and the spool. Alternatively, the formations may comprise resiliently and radially displacea...

This invention relates to an X-ray film holder and more particularly to a cassette for holding low dosage, soft tissue, X-ray film, for use in association with a mammography machine.

A magnetic tape cassette having two tape winding reels with associated brake levers pivotable between a disengaged position and a braking position for rotating the reels slightly and tensioning the tape when the cassette is not on a tape apparatus. To obtain a maximum rotation of the winding reels within the available cassette space, the levers are each journalled on a lever mount which can be actuated from outside the cassette to move from a rest position to an operating position in which the b...
