Abstract

PURPOSE:To hold data stored in a control part even when a power source to be supplied has caused a power source disconnection or a power source abnormal state, by providing a power source abnormality detecting means, and a means for supplying a backup power source to the control part. CONSTITUTION:When a power source disconnection or a power source abnormal state of a power source supplied to a control part 1 and a mechanism part 2 from a power source part 4 is detected in a backup power source supplying circuit 7, the backup power source supplying circuit 7 gives an instruction to a backup power source part 6 so as to supply a backup power source to the control part 1 and the mechanism part 2. In accordance with this instruction, the backup power source part 6 starts to supply the backup power source to the control part 1 and the mechanism part 2. In such a way, even when the power source disconnection or the power source abnormal state of the power source supplied to a printer device has been generated, data stored in the control part is held.
