PURPOSE:To cut exactly a part whose cut is required by placing a disconnection part which is required in case of adding a sub-circuit member as an additional circuit, at a position for obstructing to mount the sub-circuit member. CONSTITUTION:In case of installing sub-circuit members 411, 412... provided with circuit blocks 141, 142..., to a main substrate 40 provided with a synthesizer 6, an eliminating circuit 12, etc., slits 421, 422 for mounting the sub-circuit members 411, 412... are provided on the main substrate 40, and also a wire 43 for connecting the synthesizer 6, etc. and the circuit blocks 141, 142... is provided. Also, this wire 43 is placed so as to corss a slit 42 of the next stage. Accordingly, in case of installing an additional block by using this main substrate 40, wiring lines 43, 43b are always cut when mounting the sub-circuit member 412 of the next stage. |
