A cassette and method of use, which cassette can receive and rotatably mount a roll of photosensitive medium web. The cassette includes a housing having a first section and a second section with respective, mating margins extending in a transverse direction between opposite ends of the cassette. The second section is movable with respect to the first section between a closed position in which the mating margins abut one another so that the housing is maintained light tight, and an open position in which the margins are spaced apart. The margins can define between them a slit through which the web of photosensitive medium can pass. The cassette further has a lock assembly with at least one lock member movable between a locked position in which it restrains the second section from moving from the closed position, and a released position in which the cassette can be opened. The lock assembly further includes a handle adjacent a first end of the cassette connected to the at least one lock member so that the at least one lock member can be moved between the locked and released positions by manual movement of the handle.

Photosensitive medium cassette and method of use

An intercore for mounting a hollow photographic web roll core and to transmit rotation from an elongated spindle to the core, which spindle has one or more axially extending ramps which slope radially outward in a direction away from a front end. The intercore includes a bore to removably receive the spindle by insertion of the spindle front end first into the bore. At least one slot is present in the intercore, carrying a lug which can move radially within the slot and which is positioned such that insertion of the spindle front end first into the bore causes each lug to ride on a corresponding ramp and be urged radially outward through its carrying slot and into engagement with a hollow core positioned over the intercore. An elongated spindle is provided in another aspect, for insertion into a bore of an intercore which mounts a hollow photographic web roll core for rotation. The spindle has a front end, a rear end adapted to be rotationally driven, and one or more axially extending ramps which slope radially outward in a direction away from the front end. A drive assembly can use the intercore and the spindle together.

Paper roll drive

An adjustable self-aligning tensioner, for a drive belt, the belt tensioner being self-aligning and readily adjustable. Such belt tensioner includes a pair of idler pulleys and a support for the pair of idler pulleys. A mount rotatably carries the idler pulley support. The mount is adjustably positioned relative to the drive belt, whereby the support carried by the mount locates the idler pulleys so as to be respectively engageable with the drive belt on opposite sides thereof. A mechanism reactive with the support and the mount urges the idler pulleys into engagement with the drive belt with a force so as to provide an adjustable preselected tension on the drive belt.
