## Abstract

A miniature high speed bar code scanning element is detachably mounted within an industry standard PCMCIA card for implementation in personal computing devices.

## Claims

### Claim 1

A scanning device for reading bar code symbols comprising:
(a) a light source for generating a light beam; and
(b) a sensor for detecting the intensity of reflected light from said light beam and generating an electrical signal proportional to the intensity of said reflected light;
wherein said light source and sensor are integrally and exteriorly attached to a PCMCIA card.

### Claim 2 (depends on 1)

The scanning device of claim 1 further comprising signal processing means to receive said electrical signal and to produce a digitized signal corresponding to the bar code symbol.

### Claim 3 (depends on 2)

The scanning device of claim 2 wherein said signal processing means is located exteriorly to said PCMCIA card.

### Claim 4 (depends on 2)

The scanning device of claim 2 wherein said signal processing means is located on said PCMCIA card.

### Claim 5 (depends on 1)

The scanning device of claim 1 further comprising a scanner for scanning said light beam along a scan line across the bar code symbol.

### Claim 6 (depends on 1)

The scanning device of claim 1 further comprising an optical means for directing and focusing said beam of light.

### Claim 7 (depends on 2)

The scanning device of claim 2 further comprising a control circuit for de-energizing said light after said signal processing means has produced a digitized signal corresponding to a valid bar code symbol.
