ABSTRACT:

TECHNICAL FIELD
The present invention relates to optical data readers such as bar code readers.
BACKGROUND OF THE INVENTION
Many forms of handheld devices having an integrated optical data reader are presently available. These forms include a wand form, a gun form, a card form, and a handheld computer form.
Wand-shaped devices are typically sized and shaped like a cigar. An optical data reader such as a bar code reader is accessible at an end of the device. The wand-shaped device is held like a pencil for swiping the optical data reader across a printed code such as a bar code. Data read by the optical data reader are transmitted from the wand-shaped device to a computer via either a wireline connection or a radio frequency interface.
Gun-type devices have a handle for holding like a gun. The device includes an optical data reader such as a scanning bar code reader. An end user aims the optical data reader toward a printed code. The optical data reader is activated and deactivated by a trigger promimate to the handle. Data read by a gun-type device are typically transmitted to a computer via a wireline connection.
Examples of a card-shaped optical code readers are described in U.S. Pat. No. 4,721,849 to Davis et al. and U.S. Pat. No. 4,801,789 to Davis. U.S. Pat. No. 4,721,849 discloses a card-shaped reader having an input/output connector for interfacing with a host computer.
The handheld computer form has a bar code reader accessible at an end of a single housing. The single housing supports a keypad and a display in a manner similar to a handheld calculator.
