<p>PURPOSE:To ensure smooth confirmation and adjustment when the module units of an electronic circuit are exchanged, by setting a display part which shows the signal state of a data way in an attachable/detachable way to the data way and a signal processing unit. CONSTITUTION:A data way part 12 has a display part 16 where the light emitting diodes 14-1-14-N for display use are connected between an 0V line 11' led by a junction part 13 and a signal line group 10'. The distance is set long among the three parts 12, 13 and 16, and the part 12 is located so that the part 16 can be monitored while the part 12 is put into the slot of a housing. As a result, both adjustment and confirmation are possible for the working just by attaching a module unit 18 to a junction part 17 and without inserting the unit 18 into the slot.</p> |
