Abstract
A hand held bar code scanning device having a tactile feature in which the hand held device vibrates upon indication of a successful bar code scan. The bar code scanning device includes a scanning circuit, which outputs an acknowledge signal that indicates a successful scan. This acknowledge signal is received by a switch, which closes when the acknowledge signal is in an active state. The input of the switch is connected to a reference potential, and the output of the switch is connected to a vibration motor. When the switch closes, the reference potential is applied to the vibration motor, thereby causing the hand held bar code scanning device to vibrate. This vibration notifies the hand held operator of a successful scan.
Claims3
A tactile vibration scanning system, comprising:
- a scanner, which includes:
- a housing unit;
- a scanning device contained in said housing unit and operable for scanning an object;
- means for generating a signal when said scanning device has successfully scanned said object;
- and
- an external port mounted on said housing unit and coupled to said generating means, said external port configured to output said signal;
- and
- means external to said scanner for creating a tactile vibration in response to said signal output from said external port of said scanner.
