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.

Claims

1. A mobile telephone comprising:

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, wherein

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.

2. The mobile telephone of claim 1, wherein the mirror arrangement includes a first turning mirror and a second turning mirror for turning light reflected from the internal media through an aperture onto the beam splitter.

3. The mobile telephone of claim 1, wherein the mobile telephone includes a non-marking nib slidably mounted to be selectively moveable between a retracted position and an extended position by manual operation of a slider of the mobile telephone.

4. The mobile telephone of claim 1, further comprising an internal inkjet printhead arrangement fed with print media via the internal and external pathways defined by a body of the telephone, and an ink cartridge supplying ink to the printhead, wherein the coded data contains printing instructions for the internal inkjet printhead.

5. The mobile telephone of claim 3, wherein the slider is biased outwardly from the mobile telephone and includes a ratchet mechanism for retaining the nib in the extended position.

6. The mobile telephone of claim 5, wherein one end of the nib abuts a switch which is operatively connected to circuitry controlling operation of the LEDs and the image sensor.

7. The mobile telephone of claim 6, wherein the switch is configured to activate the LEDs and image sensor when the nib is in the extracted position and is pressed against the external media.
