<p>PROBLEM TO BE SOLVED: To obtain an electronic-circuit monitoring apparatus by which more packages can be monitored without mounting a plurality of packages for monitoring even when a connector whose number of terminals is comparatively small is used. SOLUTION: In the electronic-circuit monitoring apparatus, a plurality of packages on which electronic circuits are mounted are mounted on an apparatus body via respective connectors 32 so as to be freely detachable, and at least one package 10 for monitoring monitors the state of a package 20 to be monitored. A signal selection means 22 by which a plurality of kinds of signals are output selectively at mutually different timings to a single signal line 54 which is monitored by the package 10 for monitoring is mounted on the package 20 to be monitored.</p> |
