Abstract

PROBLEM TO BE SOLVED: To confirm residual amount of battery power by the lighting pattern of a back light section. SOLUTION: When any one of the buttons is depressed (S1), parameters V0 and V1 are initially set to a fully charged up state of the voltage of a battery 6 (S2). When it is fully charged up, they are set so that the back light section is completely lighted (S5). When it is not fully charged up (S3) and the amount of the consumption of the battery 6 exceeds an offset value, the value of addition of the offset value to the parameter V1 becomes smaller than the parameter V1 (S4), the light pattern of the back light section is changed based on the residual value of the battery power (S6) and displayed.
