IPC: G06K13/103
Filed: 1979-06-14
Abstract: PURPOSE: To miniaturize a paper feeder by making it possible to supply sheets of cut paper, contained by stacking, like a roll of paper.  
     CONSTITUTION: On an electronic desk-top calculator, printer 9 is mounted and printer 9 prints information out on cut paper 5. Through the turning of deformed axis 19, print-type ring 15 is turned to obtain character position signals by a detector (not shown in the figure) corresponding to character of print types 16 on the outer circumference. Then, those signals are compared with arithmetic results and when the both agree, frame 20 is slid as shown by arrows C and D to print desired characters, digit by digit. Frame 20 is shifted by steps as shown by arrow E to print other digits as well. On one-line print, paper feeding rolls 13 and 14 are turned at the same time as much as one line to feed cut paper 5 as shown by arrow F. The above-mentioned print operation is repeated and when cut paper 5 is not fed to the print position any more, the paper existence detector generates a signal, by which paper supply roll 10 is turned to supply uppermost paper 6' of stacked sheets of paper 6 to the print position.
