Embodiment Construction

[0055] The first embodiment of the paper discharge base of the image forming apparatus of the present invention will be described in detail below with reference to the accompanying drawings.

[0056] figure 1 is a view of the internal structure of a stencil printing machine as an image forming apparatus, to which a discharge base 10 in an embodiment of the present invention is applied.

[0057] Inside the main body 14 of the stencil printing machine 12, a plate cylinder 16 is arranged, which is formed in the shape of a cylinder rotating about its own axis. On the outer peripheral surface of the printing plate cylinder 16, there is provided a clamp member 18 for clamping an end portion of a stencil 48 which will be described later. The stencil 48 clamped by the clamp element 18 passes through the plate cylinder 16 in the figure 1 It rotates in the counterclockwise direction and is wound and fixed on the outer peripheral surface of the plate cylinder 16 .

Abstract

When the damping plate 78 of the collision wall 70 is provided on a paper discharge base 10, the paper discharge base 10 is applied with a sponge plate 84. The protection board 16 is pasted on one surface of the sponge board 84 . When the damping plate 78 is impacted by the printed sheet P, the impact force is transmitted from the protection plate 86 to the sponge plate 84 and is cushioned by the sponge plate 84 . In addition, the sponge board 84 is protected by the protection board 86 , and therefore, the sponge board 84 is not damaged by the impact of the printed sheet P. As shown in FIG.

Description

technical field [0001] The present invention relates to a sheet discharge base of an image forming apparatus such as a copying machine or a printing machine for accommodating printed sheets discharged from a printing area of ​​the image forming apparatus in a stacked state. Background technique [0002] With the rapid development of image forming devices such as copiers or printing machines in recent years, printed sheets discharged from their printing areas are discharged toward the paper discharge base at high speed, and collide against the collision wall of the paper discharge base with a large momentum. In this case, when the collision wall is a rigid structure, there is a disadvantage that a loud collision sound occurs when the printed sheets collide. [0003] Therefore, in Japanese Patent Laid-Open No. 183553 / 1997, there is disclosed a discharge base for reducing the impact sound of printed sheets. Such a paper discharge base is provided with a paper mounting table an...
