Abstract
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.
Claims6
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.
