Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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. The elastic support member pushes the light bar and the transparent plate toward the paper feeding wheel. An image scanning equipment with an image scanning device is also provided.

Abstract: An image forming device with a collapsible paper guide is provided. The image forming device includes a casing, a first tray structure and a paper guide. A medium gateway opening is formed on the casing. The first tray structure is disposed on the casing and adjacent to the medium gateway opening. The paper guide includes a first base disposed on the first tray structure and a first guiding component pivotally connected to the first base. The paper guide is switchable relative to the first tray structure between a used position and a stored position. A first included angle included between the first guiding component and the first base is less than 90 degrees when the paper guide is located at the used position, so that the first guiding component can be interfered and driven to pivotally fold for preventing the paper guide from being broken or damaged.

Abstract: A paper separating roller, including a shaft body, a first friction member and a second friction member is provided. The first friction member covers a first surface of an outer periphery of the shaft body. The second friction member covers a second surface of the outer periphery of the shaft body, wherein the first friction member and the second friction member are formed of two different materials. With the design of the friction members being formed of composite materials, the paper separating roller has the advantages of two different material features at the same time, such that a wider range of performance capabilities can be achieved.
