In the recording sheet of the invention, an ink-permeable layer contains a filler and a surfactant of 9.0 or less in HLB value and surface of the filler particles is in a state of being covered with lipophilic groups of the surfactant, and thus an ink applied to the surface of the ink-permeable layer does not spread on the surface of the ink-permeable layer but is absorbed into the ink-permeable layer and, in the ink-permeable layer, the ink does not diffuse in the surface direction but migrates straight in the depth direction. Further, addition of a cation group-containing compound as a fixing agent to the ink-receiving layer of the recording sheet serves to improve fixing properties of the colorant in the ink-receiving layer, thus no banding occurring within the ink receiving layer as well.

Abstract: A variety of information is transmitted to an electronic apparatus by using a microcomputer for low-speed processing and with saved power. A CPU acquires detection data of a thermistor, and detection data, such as the terminal voltage or the discharge current of a battery, at intervals of 10 seconds, through respective interfaces, calculates the remaining capacity and the total capacity of the battery, stores the results and the acquired data as transmission data in a RAM, and transmits this stored transmission data at intervals of one second from a communication interface to an electronic apparatus. Since the CPU transmits the data in one direction independently of the operation of the CPU on the electronic apparatus side, it is possible to greatly lower the operating clock of the CPU and to greatly reduce the consumption of power thereof.
