Done in. L in the LED display board device 3 by the temperature sensor 6
The temperature of the ED board is measured and monitored by the failure detection unit 208. When the temperature of the LED board exceeds a certain temperature, the failure detection unit 208 sets the corresponding failure flag and failure notification flag of the failure status storage unit 210 to 1 (step 22).
When abnormal heating of the LED display board is detected, the LED board display unit 202 does not perform display processing until the normal temperature is restored.

Detection of printer power-off, printer offline, and printer input abnormality is performed by the fault detection unit 208 using the printer status storage unit 211. The fault detection unit 208 refers to the printer status storage unit 211 and detects an abnormality in the printer 5. The printer status storage unit 211 has a printer status flag and stores the return value from the printer 5. The fault detection unit 208 determines which of the above faults is hit based on the value of the printer state flag, and sets the corresponding fault flag and the fault notification flag of the fault state storage unit 210 to 1. However, when the printer runs out of paper, no processing is performed on the failure status accumulating unit 210 except when an abnormal printer input / output is detected. Fault detection unit 20 is also used to detect when the printer is out of paper.
8. However, there is a difference from the above case. The detection of paper shortage is performed once every 10 minutes, and is performed only when the terminal control device unit 100 requests the paper shortage state monitoring. The failure detection unit 208 is the printer status storage unit 2
If the paper is not stored, the paper status flag 11 is set to 1 and the corresponding failure flag and failure notification flag of the failure status storage unit 210 are set to 1.
