AI Technical Summary

Problems solved by technology

When the distance between the fan and the holding member is further increased, the sealing area becomes wider, making it difficult to ensure the degree of sealing
Therefore, the possibility of intake / exhaust loss increases, and intake or exhaust efficiency becomes poor

Abstract

An image forming device whose damping component is composed of a clamping part and a main body part, wherein the clamping part is clamped to a surface (8) of a maintaining component located at an opposite side of a maintaining surface of a vibration source and is formed at one end of the main body part; the main body part is inserted into to form in a through hole on the maintaining component, and when the vibration source is fixed by a fixing part, the main body elastically distorts and forms a pressure contact with the vibration source at the same time, and the diameter of the main body part is less than that of the through hole. When the vibration source is fixed, the damping component is clamped to a surface of a maintaining component located at an opposite side of a maintaining surface of a vibration source and is inserted in it with the condition of not forming the contact with the through hole on the maintaining component, and forms the pressure contact with the vibration source (3) so as to enlarge the distance of the propagation path of the vibration.

Description

technical field [0001] The present invention relates to an imaging apparatus, and more particularly, to a vibration damping structure for preventing noise caused by vibration of a vibration generating source. Background technique [0002] Heretofore, image forming apparatuses such as printers, copiers, and the like have sheet feeding devices for feeding sheets one by one from a sheet accommodating portion in which a plurality of sheets are loaded. As for the sheet feeding device, there is an apparatus of an air sheet feeding system in which a plurality of sheets are floated by blowing air to an edge portion of a sheet bundle accommodated in a sheet accommodating portion, only one The sheet is sucked onto the suction conveyor belt arranged at the upper position and conveyed. This technique is disclosed in Japanese Patent Application Laid-Open No. H07-196187. [0003] The sheet feeding device of this air sheet feeding system has: a motor as a driving source of a suction conv...
