Abstract
An optical information reading apparatus is provided which is made of an assembly of a barcode reader and a personal digital assistant (PDA). The barcode reader and the PDA are joined through an attachment. The barcode reader includes a joint detector working to detect the joint to the PDA and a communication system establishing communication with the PDA. The barcode reader works to transmit barcode data to the PDA through the communication system only when the joint detector has detected the joint to the PDA, thereby providing ease of operability, useability, etc.
Claims63
An optical information reading apparatus comprising:
- a handheld optical information reading unit working to read optical information and output data on the optical information;
- a portable information terminal designed to receive and process information to output the information;
- and
- an attachment establishing a joint between said optical information reading unit and said portable information terminal,
- wherein said optical information reading unit includes a joint detector working to detect the joint between said optical information reading unit and said portable information terminal and a communication system establishing communication with said portable information terminal, said optical information reading unit working to transmit the data on the optical information to said portable information terminal through said communication system when the joint detector has detected the joint between said optical information reading unit and said portable information terminal, and said joint detector includes a joint sensor which senses the joint between said optical information reading unit and said portable information terminal and outputs a joint signal indicative thereof, and wherein said optical information reading unit determines that said optical information reading unit is joined to said portable information terminal when the joint sensor outputs the joint signal.
