  • Patent number: 10474073
    Abstract: A fusing device includes a driving roller and a fusing unit including a heat insulating component, a heat generating component, a heat conducting component connected to the heat insulating component, a heat reflecting component, a metal reinforcing component and a fusing component. The heat generating component and the heat reflecting component are located inside the heat insulating component. The metal reinforcing component is located outside the heat insulating component and separated from the heat conducting component. The fusing component movably surrounds the heat conducting component, the heat insulating component and the metal reinforcing component. The heat reflecting component reflects heat generated from the heat generating component to the heat conducting component. The heat conducting component conducts the heat to the fusing component. The fusing component contacts with a printing media to fuse toners onto the printing media by heating when the driving roller drives the printing media to move.

  • Patent number: 10274343
    Abstract: A rotary encoder includes a rotating shaft, first and second encoder wheels, first and second detectors and a processor. The first encoder wheel includes coaxially disposed first and second portions. The first portion has first graduation features. The second portion has a first positioning structure. The second encoder wheel includes coaxially disposed third and fourth portions. The third portion has second graduation features. The fourth portion has a second positioning structure meshing with the first positioning structure, so that the first graduation features and the second graduation features are staggered, and the first encoder wheel and the second encoder wheel are coaxially mounted on the rotating shaft. The first and second detectors detect the first and second graduation features and output first and second signals, respectively. The processor calculates a rotating angle of the rotating shaft according to the first and second signals.

  • Patent number: 10185284
    Abstract: A disassemblable imaging apparatus includes a photo sensing assembly and a toner cartridge. The photo sensing assembly has an accommodating space, a photosensitive side and a fastening side. The photosensitive side and the fastening side are respectively located at two sides of the accommodating space, which are opposite to each other. The toner cartridge includes a main body and a handle. The handle is swingably connected to a side of the main body in order to move an end of the handle, which is away from the main body, close to or away from the main body. The toner cartridge is detachably installed in the accommodating space, and the handle is detachably fastened to the fastening side of the photo sensing assembly.

  • Patent number: 10185282
    Abstract: A disassemblable imaging apparatus includes a photo sensing assembly, a toner cartridge, and at least one torsion spring. The photo sensing assembly includes a casing and a photosensitive drum. The casing has an accommodating space. The photosensitive drum is installed on the casing and located at a side of the accommodating space. The toner cartridge is detachably located in the accommodating space. The at least one torsion spring is located in the accommodating space. A part of the at least one torsion spring is installed on the casing, and another part of the at least one torsion spring presses a side of the toner cartridge facing away from the photosensitive drum for pushing the toner cartridge toward the photosensitive drum.

  • Patent number: 9815299
    Abstract: An imaging apparatus includes frame, rotatable member, exposing and imaging assembly. The frame includes accommodation space, lower and upper surfaces on the accommodation space. The rotatable member includes pressed portion, pivoting portion and arm. The pivoting portion pivots to the frame. The scanning assembly assembled to the arm and has image capturing position and lifted position. The scanning assembly at the image capturing position is away from the upper surface. The scanning assembly at the lifted position is close to the upper surface. The imaging assembly includes toner cartridge and photosensitization unit. The toner cartridge has pressing surface facing the upper surface. The imaging assembly is rotatable relative to the frame to move the toner cartridge to be alternatively close to or away from the upper surface. When the toner cartridge is close to the upper surface, the pressing surface presses the pressed portion to lift the scanning assembly.
