Patent attributes
An image acquiring device includes a scanning module, an optical signal transmission medium and a mainboard module. In the scanning module having a rechargeable battery, a scanning unit scans a document to obtain an electrical document signal, a first signal converter is connected to the scanning unit and converts the electrical document signal into an optical document signal, and a first signal transmitting unit is connected to the first signal converter and receives and outputs the optical document signal. The optical signal transmission medium is connected to the first signal transmitting unit. On a mainboard of the mainboard module, a second signal input/output unit is connected to the optical signal transmission medium and receives the optical document signal, and a second signal converter is connected to the second signal input/output unit and converts the optical document signal into the electrical document signal.
