PCT No. PCT/JP91/00450 Sec. 371 Date Nov. 26, 1991 Sec. 102(e) Date Nov. 26, 1991 PCT Filed Apr. 4, 1991 PCT Pub. No. WO91/15329 PCT Pub. Date Oct. 17, 1991.A maintenance schedule monitoring device is provided for a laser beam machine system, which is designed to monitor the maintenance schedule of the laser beam machine system. A time measuring unit (A) measures the time for which an object requiring maintenance is operating, according to information on the operation of the object requiring maintenance in the laser beam machine system. A time alarm unit (B) detects that the measured time has reached a preset time, and causes a maintenance schedule display control unit (C) to display an instruction that it is time to carry out a maintenance of the object, on a display unit (D). Thus, the maintenance and inspection schedule of the object requiring maintenance is automatically managed by automatic chronological time measurement, and when it is time to carry out the maintenance and inspection, an indication that it is time to carry out the maintenance of the object requiring maintenance is automatically shown on the display unit (D).
