Problems solved by technology

[0013] However, in the case of open-and-close type multifunction peripherals, the length of the ground cable is long, and the impedance of the ground cable increases sharply in the 10MHz and higher frequency bands
Therefore, the ground cable cannot be used as an electromagnetic noise transmission path to radiate electromagnetic noise into the space

Abstract

A multi-function peripheral is provided. The multi-function peripheral comprises an image printing unit, an image scanning unit which is openably provided on the image printing unit and scans an image, and a ground unit which is electrically disconnected or connected by opening or shutting the image scanning unit from the image printing unit and delivers electrical noise generated from the image scanning unit to the image print unit via a shortened conductive path.

Description

technical field [0001] The present invention relates to multifunction peripherals. More particularly, the present invention relates to a multifunction peripheral having a ground structure for preventing electrical noise transmitted from an image scanning unit to an image printing unit from being radiated into a space. Background technique [0002] Generally, an imaging device receives a digital image signal, forms an electrostatic latent image on a photosensitive medium through an exposure unit such as a laser scanning unit (LSU), develops the electrostatic latent image into a toner image with toner, and converts the toner image into a toner image. Transferred to a recording medium, and the toner image is fixed to the recording medium using high temperature and high pressure, thereby forming a desired image. [0003] Image forming devices are generally classified into wet type image forming devices and dry type image forming devices according to the state of toner and carri...
