The main body door opening / closing control means 500 according to the present invention configured as described above first supplies a commercial AC power input from the AC / DC adapter 501 to a predetermined DC voltage to supply the system. Here, when AC power is not supplied to the AC / DC adapter 501, the voltage charged in the battery 502 is discharged and supplied to the system.

The DC voltage output from the AC / DC adapter 501 or the battery 502 is rectified through the rectifier 505 and then supplied to the microprocessor 511 as a driving voltage.
