Abstract
A business card reader includes a scanning module, a USB detecting/switching unit and two USB ports. The business card reader is connected to at least one of a personal computer and a PDA through the two USB ports, respectively. The USB detecting/switching unit controls the data transmission path among the scanning module, the personal computer and the PDA. The business card reader has a socket electrically connected to an external power source for charging a PDA connected to one USB port.
Claims15
A business card reader connected to at least one of two external electronic devices, the business card reader comprising:
- a scanning module;
- and
- a transmission module having a first USB port and a second USB port connected to the two external electronic devices, respectively, and a USB detecting/switching unit connected between the scanning module and the two USB ports;
- when only one external electronic device is connected to the business card reader, the USB detecting/switching unit provides a data transmission path for the scanning module and the connected external electronic device;
- when both two external electronic devices are connected to the business card reader, the USB detecting/switching unit can selectively perform a data synchronization mode for the two external electronic devices or at least one data transmission mode.
A transmission module for connecting a business card reader to at least one of two external electronic devices, the transmission module controlling data transmission among a scanning module of the business card reader and the two external electronic devices, the transmission module comprising:
- a first USB port and a second USB port connected to the two external electronic devices, respectively and a USB detecting/switching unit connected between the scanning module and the two USB ports;
- when only one external electronic device is connected to the business card reader, the USB detecting/switching unit provides a data transmission path for the scanning module and the connected external electronic device;
- when both two external electronic devices are connected to the business card reader, the USB detecting/switching unit can selectively perform a data synchronization mode for the two external electronic devices or at least one data transmission mode.
