<p>PURPOSE: To provide a transmitter-receiver unit, in which a cover can be attached surely to a frame and which is suitable for miniaturizing and making it light-weight. CONSTITUTION: In this transmitter-receiver unit, a solder-rise preventing means H is installed at the frame 4 between a circuit board 1 and a book and stop part 4c. The rising of solder 5 is prevented by the solder-rise preventing means H, and the solder 5 will not reach the hook or stop part 4c. As a result, it is possible to provide a transmitter-receiver unit, in which a coupling part 6c can be coupled surely to the hook and stop part 4c, as compared with the conventional cases.</p> |
