<P>PROBLEM TO BE SOLVED: To provide an electronic apparatus which can perform predetermined treatment accompanying the break of power, when an operation of disconnecting an electric joint provided in a power supply path from an external power source to the electronic apparatus is made. <P>SOLUTION: When the plug 10 of an AC adaptor is inserted into the jack 20 of a printer, the positive electrode 13 of the plug 10 is connected to the first and second joining terminals 23 and 24 of the jack 20, and the negative electrode 14 of the plug 10 is connected to the third joining terminal 25 of the jack 20, whereby the printer is supplied with DC power. The voltage applied to the second joining terminal 24 is monitored at all times by being taken in a CPU 30 via an AD converter 36. When the plug 10 is pulled out, the second joining terminal 24 and the positive electrode 13 are disconnected in its early stage, and when the state is detected, the CPU30 is driven by DC power which is supplied while the plug 10 is pulled out of the jack 20, and data stored in an RAM 32 is written in a flash memory 33. <P>COPYRIGHT: (C)2009,JPO&INPIT |
