US Patent 7451917 Transaction terminal comprising imaging module

A transaction terminal including a display, a housing, an imaging module assembly wherein the imaging module assembly comprises a control and decode circuit, an imaging module, and a light pipe disposed optically forward of the imaging module. The light pipe may be in a tubular configuration and may include a first end disposed inside the housing and a second end extending to an exterior of the housing. The transaction terminal may include a motion detector generating a motion detection signal that serves as a trigger signal. When a motion detection signal changes state from OFF to ON, light sources of the LEDs are actuated so that a user is notified of a decoding function of the terminal.
