Abstract

PURPOSE: To ensure an visual recognition for the back-up breakage of the memory and thus avoid the mixture with other display or print or prevent the misrecognition, by giving the print or display for the message warning the breakage of the memory information.
CONSTITUTION: When the service interruption or power supply off deciding part BJ decides the off of power supply, the transfer control part SC transfers the contents of the ROM register X to the memory M in the RAM via the gate G. At the same time, the recovery of the voltage after the on of the power supply or the service interruption is decided by the deciding part AJ, and thus the coincidence deciding part J gives a decision by the control part RC between the contents of the register X and that of the memory M. And in case no coincidence is obtained, the character code generating part CRG sends the character code "LOW BATTERY" indicating the "breakage of back-up of RAM" to the print/display control part. Thus the back-up breakage of the memory can be recognized visually to avoid the mixture with other display or print or prevent the misrecognition.
