away from the exposure station 48 and the unprinted paper 10 is set at the exposure station 48 if the loop sensor d4 turns off during this frame feeding because of a reduction of the loop amount at the first loop forming section 38 the controller 100 causes the auto load motor 32 to rotate normally so that the paper 10 is pulled out of the magazine 13 until a predetermined loop amount is obtained in the meantime the negative film 53 also is fed by one frame so that the next original picture frame to be printed is set at the printing station the above operations are repeated to print one frame after another on the paper 10 the printed paper 10 is recorded with a cut mark between frames and a sort mark for each order by means of the cut sort marker 61 when a predetermined amount of loop is formed at the second loop forming section 77 the second and third paper feeding units 80 and 90 start operating so that the paper leading end is fed toward the processing section 78 when the paper leading end reaches the outer circumference of the roller 91 the roller 91 stops and the guide plate 87 changes its position therefore a loop is formed at the third loop forming section 86 when a predetermined amount of loop is formed the roller 91.
