PROBLEM TO BE SOLVED: To prevent the wave stop of the transmitting signal without using a jig. SOLUTION: A cover part 16 and a casing part 23 are formed freely to be connected and separated to/from each other. The cover part 16 is provided with an input terminal 1, an output terminal 7 and a branch circuit 4 for dividing a part of the signal, which flows between the input terminal and the output terminal 7, and the casing part 23 is provided with a distribution circuit 18, which is to be connected to the branch circuit 4 in a state that the casing part 23 is connected to the cover part 16 and which decides the divided variable and the number of branching, and dividing output terminals 19, 20, 21, 22 for outputting the signal distributed by the distribution circuit 18. With this structure, up/down signal lines are always maintained in the connecting condition even in the case where the cover part 16 and the casing part 23 are separated from each other. |
