摘要： The present invention is an imaging module including a frame supporting various optical components and a circuit board, which, in one embodiment, carries essentially an entirety of illumination and aiming LED's of the module. The frame may include resilient fingers which enable the frame to receive certain optical components in a snap-fit arrangement. Further, the module may be arranged so that the outer walls of the module provide a containment for preventing structural damage to sensitive internal components of the module.

摘要： The invention is optical assembly for use in a barcode reader that includes a frame having a rear housing and a pair of arms outwardly extended from the housing. An optical card containing an imaging lens is slidably received in a rear guideway situated between the arms. An aperture card is slidably received in a front guideway situated between the arms in front of the lens. Lamp support brackets are also mounted to either side of the arms. Each bracket contains a pair of LEDs that are aligned in coplanar relation with the imaging lens. A cylindrical lens is mounted in front of the lamp support brackets within the arms of the frame to magnify and focus the illumination from the LED upon a target in barcode space. A horizontally extended field stop aperture is positioned in front of each LED.

摘要： The present invention is an imaging module including various optical components and a circuit board, which, in one embodiment, carries essentially an entirety of illumination and aiming LEDs of the module. The module includes a combination of features which result in the size of the module being reduced. The module may comprise a refractive optic diffuser plate manufactured using a textured surface mold.
