Further, in the above-described embodiment, the IC card is used as the portable external storage device, but in addition to this, it is of course possible to use a magnetic or magneto-optical storage medium of the floppy disk type. Is. Furthermore, in the above-described present embodiment, the case where the present invention is applied to a construction machine such as a hydraulic excavator has been described in detail, but it is needless to say that the present invention is not limited to this and can be applied to other working machines. .

[0057]

As described in detail above, the present invention (claim 1)
According to (4), since the detection means, the interface section, and the portable external storage member are provided in association with the work machine, the work content of the work machine by the operator can be recorded in the portable external storage member. After the work is done, the operator can be educated by analyzing the work contents in the arithmetic unit, the workability of the operator can be improved, and the productivity can be improved. There is also an advantage that data management for evaluating such as can be easily performed.
