Abstract
A paper feeding device that feeds a sheet of a paper roll to a printing device includes two spaced-apart side plates having opposed first notches for rotatably bearing-supporting a first paper roll and opposed second notches for rotatably bearing-supporting a second paper roll that may have a different diameter in an unused state from that of the first paper roll. A near end sensor for detecting the remaining amount of the paper rolls is slidably positioned in a linear groove formed in one of the side plates. The linear groove having a longitudinal axis that passes through a midpoint of a straight line connecting a rotation center of a first paper roll bearing-supported in the first notches and a rotation center of a second paper roll bearing-supported in the second notches. When first and second paper rolls of different sizes are used, if both paper rolls are wound on paper tubes of the same size, the position of the near end sensor need not be changed, which is a great convenience for the user.
