PURPOSE:To obtain a stable data in any service started simultaneously with the operation of a power key by connecting an internal circuit direct to a power source plug except for the display section, which is connected to the power source through the power key. CONSTITUTION:A power key is provided on a front panel provided with a display section 7 in a case of an equipment. A power source cord is extend to be provided with a power source plug and an internal circuit is connected direct to the power source plug except for the display section 7, while is connected to the power source through the power key. With such an arrangement, when the power source plug is inserted, the power source is connected to the internal circuit except for the display section to stabilize the internal circuit and the display section indicates zero upon the operation of the power key thereby providing a stable data even in the service started simultaneously with the operation of the powerkey. |
