自動起動装置。 A device that makes it possible to avoid erroneous program startup due to incorrect connection of the test object when testing multiple test objects using a dedicated connection cable for a test device equipped with a function to test the test object. The object under test has a built-in resistor for identifying the object under test, and is connected to a plug to which a specific resistance for identifying the cable of each connection cable is connected in advance, and after the plug is connected to the receptacle. The test device, in which signals are transferred via the receptacle, includes a switching circuit having a plurality of switching elements connected to the receptacle and switching signals, and a switching circuit connected to the switching circuit and having a plurality of switching elements connected to the switching circuit and switching signals according to the operation of the switching elements. When the resistance measurement circuit that measures the resistance value at that time and the switch element can be controlled, and the cable recognition resistor and the test object identification resistor have a predetermined relationship from the input of the resistance measurement circuit, , and an object-under-test identification section that outputs a signal capable of requesting startup of the test program of the corresponding object under test to a program-under-test starting section that starts the test program. Automatic startup device.
