PURPOSE:To easily check the validity/invalidity of signal transmission from a function part such as a keyboard to an information processing means such as a CPU in an electronic apparatus provided with a segment display like an electronic charge balance. CONSTITUTION:Since the existence of an output signal from a function part 17 to an information processing means 12 is detected and the display state of a prescribed display element on a segment display 7 which is previously set up in each function part 17 is varied, complicated work for detaching a body housing and connecting a tester to execute test work is not required. |
