Abstract: An optical device detachably disposed on a scanner is provided, including a housing, a first opening, a second opening, a lens module, and a fixing member. The housing has a first surface and a second surface connected to the first surface. The first opening and the second opening are respectively formed on the first surface and the second surface. The lens module is disposed in the housing. The fixing member is detachably affixed to the scanner and pivotally connected to the housing. The light provided by the scanner enters the housing through the first opening, and the lens module guides the light to leave the housing through the second opening. The light leaving the housing through the second opening can fall on a scanned object.

Abstract: A circuit board and a layout structure are provided. The layout structure includes a plurality of chip carrying areas, a plurality of inner layer connection pads and a plurality of outer leading wires. The chip carrying areas respectively carry a plurality of chips. The outer leading wires are disposed between the inner layer connection pads and the chip carrying areas. The layout structure is disposed on at least one circuit board and connects to a plurality of wires of the at least one circuit board through the outer leading wires, and the outer leading wires and the wires of the at least one circuit board are formed by sharing at least one metal layer.
