摘要： PROBLEM TO BE SOLVED: To solve the problem that in the case where a rear end of rigid/stiff paper such as thick paper passes through a conveyance path divided part of a conveyance path with a small curvature, when the rear end of the paper is moved from a guide plate in the upstream side to a guide plate in the downstream side, harsh collision noise of flapping the paper against the guide plate in the downstream side and a conveyance belt of a belt conveyance means (flapping noise) is generated. SOLUTION: A driven side pulley 84 of the belt conveyance means 8 is arranged such that a relationship between a distance R1 between a paper guide outlet (downstream end 71b) and the axial center of a pulley 83 and a distance R2 between the axes of the respective pulleys 83, 84 satisfies R1 COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：解决的问题为了解决在厚纸等刚性/刚性纸的后端通过具有小曲率的输送路径的输送路径分割部分的情况下，当后端纸张从上游侧的导向板向下游侧的引导板移动，将纸张向下游侧的引导板拍打和皮带传送装置的传送带（拍动噪声）的严酷碰撞噪音为产生。解决方案：带传送装置8的从动侧滑轮84被布置成使得导纸器出口（下游端部71b）与滑轮83的轴心之间的距离R1与第一各滑轮83,84的轴线满足R1

摘要： PROBLEM TO BE SOLVED: To provide a paper carrying device, and an image forming device, capable of carrying recording paper of high stiffness and high rigidity such as thick paper without causing problems such as springing sound while maintaining advantages of space saving and low cost. SOLUTION: The device is provided with a first carrying means to hold and carry paper, a first guide member provided upstream of the first carrying means to guide to the first carrying means, a second guide member provided upstream of the first guide member to project into a carrying passage over a guide surface of the first guide member, and a third guide member provided downstream of the first carrying means to guide the paper in a different direction from the guide direction of the first guide member. As the tip of the paper is positioned at the third guide member 70 and 71, with the paper held by the first carrying means 6, the rear end of the paper is carried from the second guide member 74 to the first guide member 73, when the rear end of the paper gets in contact with the first guide member 73 with time difference along the width to reduce contact sound by means of a contact sound reducing means 76 or 77 provided on the first guide member.
