Abstract

PURPOSE:To make recording charts of accurate excavating courses by recording the laser beam position information from a main body detected at very fixed interval with a photodetector arranged with the multiple photoelectric elements provided at the leading end of an excavator in matrix. CONSTITUTION:A transit type laser oscillator 21 provided to a main body 4 of an excavator emits a laser beam C. The beam C is detected with a photodetecting part 22 arranged with multiple photodetectors in a matrix shape, by which the digital signal (d) of the photodetected position is obtained. This signal is converted to an analog signal (e) by a signal processing circuit 23. The position signal (a) emitted at every fixed distance movement of the body 4 is converted to a pulse signal (b) for marker by a signal processing circuit 26, and this signal drives a paper feed signal generating circuit 27, which emits a data holding signal (f) and a paper feed signal (g). An analog data holding circuit 24 feeds photodetected position data (h) to a recorder 28 by means of the signal (e) and (f). Thereby, the photodetected position signal is fed to the recorder 28 in synchronization with the movement for the fixed distance of the body 4, by which it is recorded and the making of the accurate excavation course charts is made possible.
