Image forming apparatus

Abstract

The invention discloses an image forming device, comprising at least one paper feeding part and a horizontal rotation shaft, the paper feeding part has: a paper roll accommodating part, which is suitable for holding a paper roll formed by winding long paper on the shaft; a roll holding portion on which a paper roll is temporarily placed; and a paper conveying portion adapted to feed out paper from the paper roll accommodated in the paper roll accommodating portion. The paper roll accommodating part includes: a holding part; a guide part arranged on a substantially horizontal line together with the paper roll holding part to guide the paper roll to the paper roll accommodating part when the paper feeding part is rotated and pulled out; A suppressing portion that suppresses the spontaneous rotational movement of the paper roll when the paper feed unit is rotated and pulled out. The horizontal rotation shaft is suitable for supporting the paper feeding part in the main body of the image forming apparatus. When the paper roll is replaced, the paper feeding part is pulled out from the main body of the image forming apparatus by rotating the paper feeding part, wherein the paper feeding part can be rotated The paper feeding part is thus pulled out to replace the paper roll.

Description

technical field [0001] The present invention relates to an image forming apparatus capable of reducing the burden of replacing paper rolls. Background technique [0002] Heretofore, in an image forming apparatus such as a large paper copying machine or a printer, a paper roll is used by installing a shaft in a core of a paper roll wound with long paper as a recording medium. In the case where the paper roll is wound with A0-sized or A1-sized paper, since the paper roll has a large width and a large weight, the operation of changing the paper roll is difficult and dangerous. JP-A-2000-289896 has proposed such a paper feeding device: that is, the paper feeding device has a paper roll holding part on its housing upper part, and the paper roll holding part allows a paper roll to be temporarily placed thereon. After the paper roll is temporarily placed on the paper roll holding member, the shaft is installed in the paper roll, and then the paper roll is lowered to the paper roll...
