ABSTRACT:
A scan velocity detector for detecting scan velocity when a surface of an object is scanned with a beam of light generated by a light-projecting element; the scan velocity detector comprising light-receiving element to receive light which is reflected, threshold-level setting element for setting threshold levels, delay element for delaying the output of the light-receiving element and counting element for counting the time from when the output of the delay element exceeds a certain threshold level until it reaches a different threshold level; the scan velocity detector being an integral part of a bar code scanner, or similar device.
