PROGRAMMABLE DISPLAY DEVICE

摘要

A programmable display device main body includes an address file detecting section for detecting whether a memory card stores a MAC address file, a password file detecting section for detecting whether the memory card stores a password file, and an activation control section for reading data from the memory card. The activation control section does not read data in a case where the memory card stores neither a MAC address file nor a password file.

主权项

1. A programmable display device, comprising:
a programmable display device main, body having a self-identifier as an identifier unique to the programmable display device main body; and an external storage medium attachable to and detachable from the programmable display device main body, the external storage medium storing data to be read by the programmable display device main body and further storing at least one of (i) an identifier-storing file containing a record identifier associated with the data and (ii) a setting-information-storing file capable of containing setting information associated with the data, the programmable display device main body including: an identifier-storing-file detecting section for detecting whether the external storage medium stores the identifier-storing file; a setting-information-storing-file detecting section for detecting whether the external storage medium stores the setting-information-storing file; and a data reading section for reading the data, the data reading section not reading the data in a case where the external storage medium stores neither the identifier-storing file nor the setting-information-storing file.
