An emergency send button(105) is configured for emergency calls in case of battery discharge. A micro computer(106) outputs a control signal to supply emergency power to the body(100) as a signal of the button(105) is inputted. A power switch(107) switches a supply voltage into the emergency power. The battery(200) comprises as follows. A supply voltage storage(201) provides the supply voltage to the body(100). An emergency power storage(202) provides the emergency power to the body(100).
