ABSTRACT:
This invention relates to a remaining paper rewinding device for a paper feeding apparatus in a printing system. This device has a simple structure with a compact size, which can be easily assembled and whose maintenance can be easily carried out.
The remaining paper rewinding device comprises a rotary shaft rotatively driven, a pair of Y-form paper roll support members which are oppositely arranged on the rotary shaft, a plurality of paper roll support stems each of which is pivotally arranged on the same circumference of the paper roll support member and in parallel to the rotary shaft so that the opposite support stems are aligned with each other, a plurality of drive units each of which is assembled on the paper roll support stem arranged on at least one side of the paper roll support members, and a drive power transmission unit which can be selectively engaged with the drive unit to transmit the rotating drive force from a power unit to the engaged drive unit.
