Abstract: An overhead scanner 1 includes an imaging unit 22 that images a medium S placed on a mount surface 2 to be read from above and a light source 21 that is arranged to be able to irradiate the medium S with light during imaging by the imaging unit 22. A control device 40 of the overhead scanner 1 performs anti-glare control when detecting that the medium S is glossy. This prevents glare from occurring to the user during operation of the overhead scanner 1.

Abstract: Imaging devices and methods that permit the capture of digital images of an original document sequentially illuminated by a plurality of light sources. In one aspect, a first digital image is captured using illumination from a first illumination angle, a second digital image is captured using illumination from a second illumination angle, and the first and second digital images are combined to obtain a composite digital image of the document. The obtained composite digital image is free of reflection artifacts corresponding to the first and second illumination angles.

Abstract: An optical scanning device with a dustproof function includes a shell defining a first receiving room and a second receiving room communicating with the first receiving room through an open window defined on the shell for scanning light beams passing therethrough. An optical scanning module is mounted in the first receiving room. A glass platform is located on the second receiving room at a position facing the open window for insulating the first receiving room from the outside of the shell. A correcting plate is stuck on the bottom of the glass platform. Such structure of the optical scanning device enables the glass platform to be firstly assembled with the shell in a dustless chamber, which prevents the suspending dust from falling in the first receiving room and attaching to the optical scanning module during the subsequent assembly process and ensures the scanning quality of the optical scanning device.

Abstract: An optical reading device of a scanning apparatus includes two light sources and a movable lens. The first light source emits a first light when the optical reading device is operated in a flatbed scanning mode. The second light source emits a second light when the optical reading device is operated in a sheetfed scanning mode. The movable mirror is selected to allow for passing the first light without being obstructed by the movable mirror in the flatbed scanning mode or allow for reflecting the second light coming from the second mirror in the sheetfed scanning mode. Due to the special design, the overall volume of the scanning module is reduced.

Abstract: A focus adjusting device (50) for an image sensor (1) is provided for ensuring precise focusing of the image sensor. The focus adjusting device includes a contact element (51) in direct contact with the bottom of a scanner cover plate, a focus varying element (53) engaging with the contact element, and a focus fine adjusting element (55) movably mounted on a housing of the image sensor. The focus varying element and the contact element are driven to correspondingly move vertically together with the vertical movement of the focus fine adjusting element, whereby the distance between an upper surface of the housing and the bottom of the cover plate is thus changed for precise focusing.
