<p>A transmitter-receiver unit is disclosed wherein a frame is provided with solder-rise preventing means (H) between a circuit board (1) and retaining portions (4c), thereby preventing solder from rising up to the retaining portions. Thus, the engagement between engaging holes and the retaining portions is ensured in comparison with the prior art. The transmitter-receiver unit permits a cover to be mounted positively to the frame and is suitable for the reduction of size and weight. <IMAGE></p> |
