<p>PROBLEM TO BE SOLVED: To reduce the possibility of a theft of a construction machine by shortening a collation time of fixed data for identifying a worker and reinforcing a theft prevention mechanism. SOLUTION: When a discrimination code is selected by selection switches 21-24 of a display screen 13, the discrimination code is transmitted to a monitor controller 15, an identification code corresponding to the selected discrimination code is transmitted from the monitor controller 15 to a fingerprint collation unit 6, and the fingerprint collation unit 6 selects fingerprint data corresponding to the selected discrimination code. The finger print data detected by a fingerprint sensor 7 of the fingerprint collation unit 6 and the selected fingerprint data are collated with each other and, when they coincide each other, a working machine is set in a prescribed state. The fingerprint collation unit 6 is detachably attached to a fingerprint collation unit installation part 5a of a driver's seat 3. When a shutter 8 of the fingerprint collation unit 6 is open/ closed, the display screen 13 is shifted to a fingerprint input guide screen.</p> |
