An optical pattern reading apparatus includes a housing with a light projecting means located within the housing for projecting a line of light onto an optical pattern located external to the housing and wherein the line of light is cyclically swept across an optical pattern to be read. A reflecting mirror located in the housing, posteriorly of the light source is moved in synchronism with the line of light projected onto the optical pattern to receive a line of light reflected from the optical pattern and projecting its reflected light via a light receiving and condensing optics assembly onto a linear image sensor. The information present within an area can thus be sensed using a linear image sensor.
