PROBLEM TO BE SOLVED: To switch a mode to a manufacturing time mode only by means of extracting/insertin1g a connector and to shorten work time by supplying a manufacturing time mode start trigger signal to a port for manufacture time mode start trigger signal input when an external unit is connected to a port for external unit with the connector for external unit connection. SOLUTION: When a unit is in a non-connection state where a male connector 7B is extracted from a female connector 7A, the port for manufacturing time mode start trigger signal TERM is opened and it becomes a high level when CPU 6 becomes an active state by means of the supply of power. A regular operation modes is started with such state as a regular operation mode starting condition. When the female connector 7A is inserted into the male connector 7B and the unit is made into a connection state, the port TERM is grounded and it becomes a low level since the connection terminals 7A3 and 7A4 of the female connector 7A are shorted by the connection terminals 7B3 and 7B4 of the male connector 7B. Consequently, CPU 6 detects the level change of port TERM and starts the manufacturing time mode. |
