Abstract: A data sending program in a first microprocessor system of a data sending intelligent instrument includes a sending action command judging program. If the sending action command judging program judges that an action for operating an image by a user matches a preset data transmitting command, data corresponding to the image is transmitted. A data receiving program preset in a second microprocessor system of a data receiving intelligent instrument includes a receiving action command judging program. If the receiving action command judging program judges that an operating action by the user matches a preset data receiving command, the data is received. The image corresponding to the data received is generated in a page which the use executes the operating action on. Instead of executing operations by the user in prior art, the program controls a sending and receiving process and executes the operations.
