Deformed example 1

[0065] For example, in the above embodiment, the controller 24 retries steps S01 to S06 when the read voltage management flag F is "1" (step S07: YES), but the control method of the information display device Not limited to this. The information display device may skip steps S01 to S04 and retry only steps S05 and S06 when it can be confirmed that the transmitted display information is recorded in the recording unit 31 as display data. In addition, the information display device may not execute the retry process when the read voltage management flag F is "1", and may only present an error message.

Deformed example 2

[0067] For example, in the above-mentioned embodiment, the communication control unit 2 and the display control unit 3 are independent of each other, but the configuration of the information display device is not limited to this. In the information display device, the communication control unit 2 and the display control unit 3 may be configured integrally.
