Image forming device and paper discharging mechanism thereof

Abstract

The invention discloses an image forming device and a paper discharging mechanism thereof. The paper discharging mechanism comprises a first tray, a pushing part, a second tray, a pressure part and a protrusion part, wherein the first tray is used for bearing paper discharged from a paper outlet in the discharging direction; the pushing part is used for pushing out the paper on the first tray in the paper discharging direction; the second tray is located on the downstream part of the first tray in the paper discharging direction to bear the paper pushed out by the pushing part, and the upstream end of the second tray is lower than the downstream end of the first tray; the pressure part is used for pressing the paper on the first tray; the protrusion part is located on the side, near the second tray, of the first tray in the paper discharging direction, and the paper can be supported on the protrusion part when discharged in the paper discharging direction and forms an arch shape extending in the paper discharging direction. The novel paper discharging mechanism is invented and does not damage paper, and the problem that the waist part collapses when the paper is discharged in the paper discharging direction is avoided.

Description

technical field [0001] The invention relates to an image forming device and a paper discharge mechanism thereof. Background technique [0002] With the rapid development of science and technology, human beings have already entered the information age. Computer peripheral products and other related image forming devices, such as copiers, printers, scanners, fax machines, photocopiers or multi-functional ones with functions such as copying, scanning, printing and faxing The MFP can not only help improve the efficiency of people's processing information, but also speed up the communication between people. [0003] As user needs become more and more diverse, the functions of existing image forming devices are not limited to forming images on paper, but can also implement the following function: post-processing the paper on which images are formed. For example, the post-processing may be punching, stapling, clamping and so on. [0004] An existing image forming apparatus capabl...

Problems solved by technology

[0006] However, the paper discharge mechanism of the above-mentioned conventional image forming apparatus has the following problem: in the process of pushing the paper P on the first tray 1 to the second tray 3 by the pushing part 2, if the paper P is not bound or clamped, Then the paper may be skewed (that is, the rear end of the paper is no longer completely attached to the ejection part 2), and the paper P cannot be discharged neatly.

This will not only cause the rear end of the paper P to escape from the pressure part 4 before the paper P is completely discharged (that is, the pushing part 2 stops pushing the paper P), so that the paper P cannot be discharged smoothly, but also cause: Figure 4 As shown, even if the paper P is discharged smoothly, the rear end of the paper P will be placed on the second tray 3 in a bent state, which will affect the next discharge of paper and the stowage performance of the second tray 3
