Title:
AUTOMATIC PAPER SHEET CARRYING MECHANISM OF PRINTER
Document Type and Number:
Japanese Patent JP3295830
Kind Code:
B2
Abstract:
PURPOSE: To reduce the friction load at the paper sheet reverse turn time and also save a space by reducing the number of parts of a roller in the automatic paper sheet carrying mechanism of a usual printer.
CONSTITUTION: A paper feed roller 4 stops under a state contacted to a loading paper sheet 9. By the rotation of a paper feed roller drive shaft 1, the loading paper 9 is fed by the rotation of the paper feed roller 4 and carried to a tension roller 15. When the loading paper sheet 9 reaches the tension roller 15, a roller position control gear is rotated and the paper feed roller 4 generates an off-centered motion around the paper feed roller drive shaft 1 and is rotated in a right direction. At this time, the rotary motion is given to the paper feed roller 4 through a roller drive gear 2 and an inner teeth planet gear 3 by the paper feed roller drive shaft 1. When the paper feed roller 4 is press-contacted with the tension roller 15 and reaches upto a position in which a paper sheet extracting force can be generated, only the rotation of the roller position control gear is stopped.
