PURPOSE:To prevent a report, which indicates that reservation is possible or impossible, from being delayed for a long period, by retrieving equipment data and time data by not a central control unit but a CPU. CONSTITUTION:A central control unit 11 prepares a reservation information retrieval request command in a main storage 15 to start a CPU 12. When receiving this command, the CPU 12 takes out a task registered in a reservation impossibility report queue 143 or a reservation possibility report queue 144 in a RAM 14 in accordance with a retrieval result report program in a ROM 13. Then, a retrieval result report status is generated. The CPU 12 writes this status in the main storage 15 and reports the retrieval result to the central control unit 11. If the program in the ROM 13 runs away because of trouble or the like, the central control unit 11 causes the CPU 12 to execute a reset acceptance execution program in the ROM 13. |
