In the drawing, reference numeral 101 denotes a portable radio telephone, and 102 denotes a battery unit in which a battery or the like of the portable radio telephone is built. A power supply terminal 102a for supplying power to the battery is provided at the bottom. The power supply terminal 102a is exposed on the bottom surface of the battery unit 102 and cannot be normally viewed from the side surface of the portable wireless telephone 101, and therefore its presence is indicated by a broken line in the figure. Reference numeral 103 denotes a holding table for holding the portable wireless telephone 101, and has a concave portion 103a which is fitted and held and fixed to the portable wireless telephone 101. Reference numeral 104 denotes a power supply terminal for supplying power by contacting the power supply terminal 102a of the portable wireless telephone 101 when the portable wireless telephone 101 is mounted in the concave portion 103a of the holding base 103.

Next, the operation will be described. As shown in (a), the portable wireless telephone 101 is inserted into the concave portion 103a from above the holding base 103. Next, as shown in (b), the portable wireless telephone 101 is fitted and held in the recess 103a of the holding base 103.
