The invention relates to a scanning tablet, pertaining to the field of computer peripheral input equipment. The device comprises a tablet panel; the tablet panel is fixedly connected with an electromagnetic pressure sensor circuit board and a pressure-sensing processor; the device also comprises a scanner, a function switch and a concentrator which consist of a mechanical driver, an optical imager and an photoelectric converter connected in sequence, and one end of the photoelectric converter and one end of the pressure-sensing processor are respectively connected with the concentrator and the function switch. The invention comprises the functions including pressure-sensing tablet operation and scan input of picture and text; therefore, the tablet can recognize large-size words and images. The conversion between the two functions of tablet operation and scan input is simple and quick. Furthermore, tablet operation and scan input are respectively connected with a USB interface concentrator, so as to accomplish input into a computer by the USB concentrator, thus reducing connecting wires and solving the problems of large volume and inconvenient operation in the prior art. The tabletcombines the two functions of tablet operation and scan input in a single product, thereby greatly saving operation space.
Description
technical field [0001] The invention belongs to the field of computer external equipment input, and relates to an input device, in particular to a digital board with a function of large-scale scanning. Background technique [0002] The digital board is the external input device of the computer, and the scanner is to realize the scanning input of text images. For image processing and text workers, the two are undoubtedly irreplaceable computer assistants. The existing digital board technology is relatively mature, and the widely used digital boards include electromagnetic induction boards and capacitive touch panels. The electromagnetic induction board emits electromagnetic waves through the transmitting circuit of the digital board, and the high-order harmonics of the electromagnetic waves cause the resonant circuit in the digital pen to resonate, and the resonant electromagnetic waves are received by the receiving circuit in the digital board to obtain the position and pres...
