Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
123 words
A roll fed copying machine comprising a frame; a bed for receiving a roll of sensitized copy paper, said bed including: a pair of rollers for supporting said roll, a pair of arms extending along either end of said roll for maintaining said roll therebetween, a pair of idler pulleys, a loop of flexible cord looped around said idler pulleys; said arms being attached to said loop, said pulleys and arms being disposed in alternating positions around said loop, the movement of one of said arms with respect to the other arm acting to move said other arm in a symmetrical fashion with respect to said one arm; and means for cutting and feeding sheets of said sensitized copy paper from said roll.
Claim 2
Dependent Claim
123 words
A roll fed copying machine comprising a frame; a bed for receiving a roll of sensitized copy paper, said bed including: a pair of rollers for supporting said roll, a pair of arms extending along either end of said roll for maintaining said roll therebetween, a pair of idler pulleys, a loop of flexible cord looped around said idler pulleys; said arms being attached to said loop, said pulleys and arms being disposed in alternating positions around said loop, the movement of one of said arms with respect to the other arm acting to move said other arm in a symmetrical fashion with respect to said one arm; and means for cutting and feeding sheets of said sensitized copy paper from said roll.
Claim 3
Dependent Claim
95 words
The copy machine of claim 1 in which the original to be copied is passed through said copy machine and wherein said cutting and feeding means include: switch means for initiating the feeding of said copy paper from said roll upon sensing the leading edge of said original and for controlling the cutting of said copy paper upon the sensing of the trailing edge of said original, and means for inhibiting the cutting of said copy paper until a predetermined length of copy paper has been fed indipendently from the sensing of said trailing edge.
