ジ。[Claims for Utility Model Registration] A memory cartridge comprising a semiconductor memory for storing data and a battery as a power source for the semiconductor memory, comprising voltage detection means for detecting a drop in voltage of the battery, and a liquid crystal display. and a warning display surface with a warning mark are stacked on top of each other, and the display surface of the liquid crystal is provided so as to be exposed to the outer surface of the memory cartridge, and when the liquid crystal is driven, a warning display surface with a warning mark is stacked on top of the other. The warning mark becomes invisible from the outer surface of the memory cartridge when the liquid crystal is turned off, and when the liquid crystal is not driven, the display disappears from the display surface of the liquid crystal, so that the warning mark becomes visible from the outer surface of the memory cartridge. and a liquid crystal drive means that drives the liquid crystal when the voltage detection means does not detect a drop in the voltage of the battery, and stops driving the liquid crystal when it is detected. Characteristic memory cartridge.
