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: A multi-mode scanning device for scanning an original includes a non-transparent element, a first light source, a second light source and an optical module. The first light source outputs visible light to irradiate the non-transparent element and the original to generate first light and second light, respectively. The second light source outputs invisible light to irradiate a combination of the non-transparent element and the original to generate third light and fourth light. The optical module receives the first light, the second light, the third light and the fourth light and generates sensing signals representative of visible light information and invisible light information of the original. The original is disposed between the non-transparent element and the optical module. The first light source and the optical module are disposed on a same side of the non-transparent element.
