Abstract
A mobile telephone includes an optical sensing arrangement enabling the telephone to decode tags of coded data printed on media fed through the telephone via internal and external media pathway defined by a body of the telephone; a beam splitter deflecting incoming light onto an image sensor of the telephone; a first infrared LED directing light onto media present in the external pathway; a filter and lens arrangement receiving and directing light reflected from the external media onto the beam splitter; a second infrared LED directing light onto media present in the internal pathway; and a mirror arrangement directing light reflected from the internal media into the beam splitter. The coded data contains printing instructions for the printhead, and the filter and lens arrangement includes an infrared filter for removing non-infrared ambient light, whereby a signal to noise ratio of the reflected light is improved.
