ている。(Embodiment) FIG. 1 shows a configuration of an embodiment of the present invention, in which 1 is a receiver-side housing in which a receiver (not shown) and the like are mounted, 2 is a transmitter ((not shown) and the like, In addition, the handset-side housing having the operation unit 3 and the like exterior is used, and the grip portion 2 of the transmitter-side housing 2 is provided.
The length a is longer than the length of the grip portion 1a of the receiver-side housing 1. Reference numeral 4 denotes an insulating housing that is interposed between the receiver-side housing 1 and the transmitter-side housing 2 to electrically insulate them. Reference numeral 5 denotes the receiver-side housing 1 and the transmitter-side housing. The antenna feeding point 5 electrically excites the antenna 2 and the antenna feeding point 5, which is actually installed in the receiver side casing 1 or the transmitter side casing 2.
