Abstract
An apparatus comprising a reproduction machine and a casing therein to hold a spool of light sensitive paper. The casing has a movable cover which forms an opening together with the casing for the light sensitive paper. The cover, when in a closed position has a light tight relationship with the casing. The cover is provided with at least one recess to avoid interference with the internal structure of the machine when the cover is opened.
Claims25
Apparatus comprising a reproduction machine including internal structure, a casing releasably located within said machine, a spool for light-sensitive paper within said casing, a movable cover on said casing and having open and closed positions relative thereto, said cover and casing forming an opening for the light sensitive paper on said spool to leave said casing and enter into the internal structure of said reproduction machine, said cover, when in a closed position with the light sensitive paper leaving said casing, having a light-tight relationship with said casing, means on said casing to cooperate with the cover to maintain said light-tight relationship, and locking means for locking said cover in said closed position, said locking means comprising a latch means and a recess means, said latch means and recess means being associated with said cover and said casing, said latch means being movable between a first position in which it is released from said recess means and a second position in which it is engaged with said recess means, said latch means being constructed to prevent admission of light into said casing when the cover is closed and said latch means is in its first and second positions.
A paper holder for light sensitive paper to be used in a reproduction machine comprising a casing, a spool for light sensitive paper within said casing, a movable cover on said casing and having an open and closed position relative thereto, said cover and casing forming an opening for the light sensitive paper on said spool to leave said casing and enter into the internal structure of said reproduction machine, said cover when in a closed position with the light sensitive paper leaving said casing having a light tight relationship with said casing, means on said casing to cooperate with the cover to maintain said light tight relationship, and locking means for locking said cover in said closed position, said locking means comprising a latch means and a recess means, said latch means and recess means being associated with said cover and said casing, said latch means being movable between a first position in which it is released from said recess means and a second position in which it is engaged with said recess means, said latch means being constructed to prevent admission of light into said casing when the cover is closed and said latch means is in its first and second positions.
A method for installing a roll of light sensitive reproduction paper into a reproduction machine having an internal structure comprising placing an openable substantially light tight casing into said machine, opening said casing, positioning the roll of reproduction paper into said casing, inserting one end of the light sensitive paper into the internal structure of the reproduction machine, closing said casing and releasably locking said casing by moving a closure latch to a closed position, the latch blocking light entry into the casing in locked and unlocked conditions of the casing.
