Patent number: 11827477Abstract: A medium passage switching mechanism disposed on a casing of an image forming device, includes a medium tray, a guiding component and a resilient component. An entrance passage, a first exit passage and a second exit passage are formed inside the casing. The medium tray is pivoted to the casing and can pivot between a first position and a second position. The guiding component is pivoted to the casing and can pivot between a third position and a fourth position. The resilient component abuts against the guiding component and the casing. When the medium tray pivots between the first position and the second position, the guiding component can be driven by cooperation of the resilient component and the medium tray to pivot between the third position and the fourth position for guiding a medium to enter into the first exit passage or the second exit passage from the entrance passage.Type: GrantFiled: September 14, 2021Date of Patent: November 28, 2023Assignee: AVISION INC.Inventors: Wei-Lun Tsai, Min-Hao Chang

Patent number: 11588947Abstract: An image scanning device includes a casing, a paper feeding wheel, a transparent plate, a light bar, and an elastic support member. The transparent plate includes a first surface and a second surface, and the first surface faces the paper feeding wheel. The light bar is located on the second surface of the transparent plate and includes a plurality of light-emitting elements. A position at which the paper feeding wheel is tangent to the first surface defines a tangent position, a position at which the light-emitting elements are projected onto the first surface in a normal direction of the first surface defines a scanning position, and a scanning spacing exists between the tangent position and the scanning position.

Patent number: 11553096Abstract: A flip-cover multifunctional image forming device includes a lower body, a first image forming module, a cover body, at least one pivoting mechanism, an upper body and a second image forming module. The first image forming module is disposed inside the lower body. The at least one pivoting mechanism is connected to the lower body and the cover body and for pivoting the cover body relative to the lower body between a folded position and an unfolded position. The upper body is detachably disposed on a side of the cover body away from the lower body. The upper body is driven by the cover body to move relative to the lower body when the cover body pivots relative to the lower body. The second image forming module is disposed inside the upper body. The present invention has advantages of simple structure, easy operation and flexibility in use.Type: GrantFiled: September 23, 2021Date of Patent: January 10, 2023Assignee: AVISION INC.Inventors: Min-Hao Chang, Hung-Chih Lee, Chao-Yu Peng

Publication number: 20220070319Abstract: A flip cover device is provided and includes a cover, a main body and a hinge. The hinge is disposed on the main body and pivotally connected to the cover in a detachable manner for allowing the cover to pivotally unfold relative to the main body. The hinge includes a hinge body and a notch structure formed on the hinge body. The cover abuts against the main body when the cover pivotally unfolds relative to the main body to an unfolded position along a first pivoting direction. When the cover is located at the unfolded position and forced by a torque along the first pivoting direction, the cover is driven by a reaction force provided by the main body to disengage from the hinge, which prevents a damage of the cover caused by an improper and excessive pivotal movement of the cover. Besides, a related hinge is further provided.Type: ApplicationFiled: August 5, 2021Publication date: March 3, 2022Applicant: AVISION INC.Inventor: Min-Hao Chang
