Printed paper feeding device for photograph processing apparatus

Claim 1

A print paper feeding device for photograph processing apparatus comprising a cut marker which can make a cut mark between two adjacent picture frames of a tape-shaped print paper simultaneously with printing it, a first roller means which can intermittently feed said print paper by a length corresponding to one picture frame, a stocker which is set in the rear of said first feeding roller and can contain said print paper portion fed out of said first feeding roller means, a second feeding roller means which is arranged in the rear of said stocker and is to pull said print paper within said stocker out of said stocker, a cut mark senser which is set in the rear of said second feeding roller means and can detect said cut mark and issue a signal to stop said second feeding roller means whenever a length portion corresponding to one picture frame of said print paper is fed, a cutter which is set in the rear of said cut mark senser and can cut the print paper in the position of said cut mark, a third feeding roller means which is arranged in the rear of said cutter and is rotated at a velocity lower than of said second feeding roller means to form a loop of said print paper between it and said cutter, a loop senser which is arranged between said cutter and third feeding roller means and can issue a signal to start said second feeding roller means when said loop becomes smaller than a predetermined size, and a controller which can receive signals from said cut mark senser and loop senser to control the respective operations of said cut marker, first feeding roller means, second feeding roller means and cutter; the size of said loop being maintained between a predetermined lower limit and an upper limit obtained by adding a length corresponding to one picture frame portion to said lower limit by said loop senser; and said print paper being cut in the position of said cut mark by said cutter when the number of said cut marks of the print paper portion which has been fed into a processor by said third feeding roller means attains a predetermined value and said second feeding roller means is stopped.
