A radio apparatus capable of downloading predetermined data such as music data from a download site through a radio communication line in which data is downloaded from a download site and sequentially written in a recording medium. When a voltage value of a battery becomes smaller than a threshold value required by a recording and reproducing section to write data in the recording medium, the downloading is interrupted. Thereafter, when an apparatus body is placed on a charging stand so that the voltage value becomes greater than the threshold value, the downloading of remaining data of the above-mentioned music data is resumed automatically. Thus, the radio apparatus can be miniaturized and made light in weight by using a battery of a small capacity as the battery. Further, the music data need not be downloaded over again from its beginning so that the communication charge can be avoided from being wasted. Furthermore, the downloading can be easily resumed by only placing the apparatus body on the charging stand. |

DETAILED DESCRIPTION It is an object of the present invention to provide a radio apparatus which can be miniaturized and made light in weight by using a battery of a small capacity and in which a communication charge can be avoided from being wasted.
According to an aspect of the present invention, there is provided a radio apparatus powered by a rechargeable battery and which is capable of downloading predetermined data through a radio line.
This radio apparatus is comprised of a data transmission request means for requesting the download site to transmit said predetermined data, a data reception means for receiving the predetermined data transmitted from the download site, a data recording means for sequentially writing the predetermined data received at the data reception means in a recording medium, a voltage detection means for detecting a voltage value of the battery, a write interrupt control means for interrupting the data recording means to write the predetermined data when a voltage value detected by the voltage detection means becomes smaller than a threshold value required by the data recording means to write data in the recording medium, line disconnection means for disconnecting a line between the radio apparatus and the download site when the writing of the predetermined data is interrupted, a memory means for memorizing a telephone number of the download site and information of the predetermined data the writing of which was interrupted, a line connection means for connecting a line between the radio apparatus and the download site by using the download site telephone number memorized in the memory means when the voltage detected by the voltage detection means becomes greater than the threshold value after the line was disconnected, a data resend request means for requesting the download site to transmit remaining data of the predetermined data the writing of which was interrupted by informing the download site of information of the predetermined data memorized in the memory means after the line was connected and a resume control means for controlling the data recording means such that the recording means writes the remaining data received at the data reception means in the recording medium
