An optical code scanner (105) is described. The scanner (105) comprises: a cashier side window (230); a customer-side window (235); an image capture device (145) for reading optical codes (245,250); and an image directing device (155). The image directing device (155) is selectively movable between (i) a cashier-scanning position at which light is directed from the cashier-side window (230) to the image capture device (145) and (ii) a customer-scanning position at which light is directed from the customer-side window (235) to the image capture device (145). The scanner (105) also comprises: a light level detector (150) for detecting an amount of ambient light passing through the customer-side window (235); and a processor (111) for moving the image directing device (155) from the cashier-scanning position to the customer-scanning position in response to the light level detector (150) indicating that the ambient light detected is below a threshold. |
