Impact reduction device and image forming apparatus

Abstract

The invention is aimed to provide an impact reduction device capable of reducing the impact of two members which can be independently rotated and an image forming device.An impact reduction device includes a pressing mechanism in an open-close device to press a first member in a direction in which the first member returns to an initial state. The open-close device includes the first member independently rotatable around a shaft from the initial state to a first angle, and a second member integrally rotatable with the first member around the shaft from the initial state to a second angle greater than the first angle. The pressing mechanism presses the first member in the direction in which the first member returns to the initial state using a first force until the first angle is reached, and presses the first member in the direction in which the first member together with the second member returns to the initial state using a second force greater than the first force between the first angle and the second angle.

Description

technical field [0001] The present invention relates to a shock mitigation device and an image forming device. Background technique [0002] Many image forming apparatuses are equipped with a member such as a cover or a door that can be opened and closed around an axis for the user to replace paper or consumables, or to remove jammed paper. When operating a cover or a door in such an image forming apparatus, since the user's force to open and close the cover or door varies, a shock absorbing device is mounted to limit the shock during opening and closing within an allowable range. [0003] Patent Document 1 describes an image forming apparatus in which a sheet feeding tray is provided so that it can be pulled out to the front side of the apparatus. In this image forming apparatus, the paper feed tray is positioned in the front-rear direction by a pressing mechanism that pushes the paper feed tray toward the front from the rear of the paper feed tray, and by the pushing mech...

Problems solved by technology

However, when a plurality of covers with different required loads are aligned with one shock absorber to buffer one load, it may cause damage to the other part or cause one cover to not be fully opened.

Therefore, it is usually necessary to install a dedicated impact mitigation device for each component, which increases the space due to the installation of the impact mitigation device, or cannot reduce the number of parts.
