Abstract
An operation state display apparatus is disclosed having a first memory device for memorizing a time from an operation initiation reference time when an input signal is switched from the ON state to the OFF state or from the OFF state to the ON state wherein each input signal is for each operation state of a controlled object. A second memory device is provided for memorizing a last time of the OFF state or the ON state after switching from the ON state to the OFF state or from the OFF state to the ON state as the time from the operation initiation reference time. The apparatus includes a display device for displaying the operation state of the controlled object depending upon the data of the first and second memories in the form of a time chart.
