In a wireless input transmission device, data is entered by input means such as pointing device, the value of the data is checked when transmitting the data, and when the data value is small and does not require the specified number of bits, the number of bits is decrease to one half or one quarter, or the difference from the previous time is transmitted, or the data is omitted if the present data is same as the previous data, and such information is given to the data quantity information bit, and data to be transmitted, data quantity information bit, and necessary data for transmission are added, and the transmission data is composed by decreasing the data quantity in one-input information depending on the data value and transmitted to the wireless receiver, where the transmission data is decoded according to the data quantity information bit and the received result is sent by wire to the main apparatus such as personal computer, word processor, other information processing apparatus, or household game machine, thereby preventing increase of current consumption used in communication in the wireless input transmission device and extending the battery life.
