PROBLEM TO BE SOLVED: To obtain a wrist portable receiver with a valid antenna shape within a limited size by arranging integrally an antenna made of a conductor material to a case and incorporating a reception circuit in the case. SOLUTION: An antenna input section pattern 33 of a board 27 has a feeding port 15 from which an antenna current is supplied and a side face opening 13 to which a pushbutton 35 for operating the receiver is inserted, the receiver has an antenna 11 made of a conductor material looped horizontally to an arm, a case 17 having a pushbutton hole 23 to which the pushbutton 35 is inserted, and using the antenna 11 as a core material on which a resin being a nonconductive material is coated, a reception circuit 29 and a liquid crystal display device 25 or the like are mounted. Through such a constitution, a radio wave received by the antenna 11 is given to the antenna input section pattern 33 of the board 27 via the feeding hole 15 and demodulated by a reception circuit 29 mounted on the board 27, sent to the liquid crystal display device 25 via a transmission line 31, on which a reception message and accurate corrected time are displayed. |
