    摘要： An imaging based bar code reader for imaging and decoding a target bar code. The reader features a housing including a scanning head defining a horizontal axis and an imaging system supported by the housing for imaging the target bar code. The imaging system including a 2D sensor array and focusing optics receiving reflected illumination from the target bar code through the window and focusing the reflected illumination onto the sensor array. The sensor array includes an orthogonal array of pixels and defines a horizontal axis. The reader further features a decoding system for decoding an image of the target bar code. The sensor array is oriented such that the horizontal axis of the sensor array is at an acute angle with respect to the horizontal axis of the target bar code when the target bar code is being presented to the scanning head such that the horizontal axis of the target bar code is substantially parallel to the horizontal axis of the scanning head.

    摘要： The invention relates to a scanning device for reading bar code symbols, wherein the scanning device comprises a housing having a substantially horizontal surface and a substantially vertical surface. A motor rotates a polygon mirror, which reflects a light beam from a light source and redirects it toward a mirror array and out a window in the substantially horizontal window. Another motor rotates another polygon mirror, which reflects a light beam from a second light source and redirects it toward a second mirror array and out a window in the substantially vertical surface. A plurality of sensors detects light reflected back from a bar code and generates a plurality of electrical signals proportional to the intensity of the reflected light.
