That is, 0 to 100% of the electric energy is divided into first to fourth levels, the first level is 10% or less, the second level is 11-30%, the third level is 31-90%, and the fourth level. The level is assigned to 91-100%. At the first level, the light source repeats red flashing, at the second level, the light source repeats orange flashing, at the third level, the light source repeatedly flashes yellow, and at the fourth level, the light source is yellow. It comes to light up.

  Further, the voltage level of the secondary battery 31 (remaining power of the secondary battery 31) in the output mode, that is, when the device is charged is determined as follows. That is, the amount of electric power 0 to 100% of the secondary battery 31 is divided into two stages of a first level and a second level, and the first level is divided into 0-5% and the second level is divided into 6-100%. At the first level, the light source repeats blinking red until the remaining power is exhausted. At the second level, the light source is turned off after a set time (a fixed time after the switch is pressed), but the device continues to be charged. In addition, at the second level, for several minutes when charging is completed (remaining power 100%), the light source repeatedly flashes red to notify the completion of charging.

  In this embodiment, the light source of the light-emitting display unit 34 depends on the voltage level of the secondary battery 31 (remaining power of the secondary battery 31) by the action of the display unit control circuit 35 when charging the secondary battery or charging the device. Although the operation that is performed as illustrated in FIG. 4 has been described, the operation of the light source is not limited to the case of FIG. For example, the level of the voltage level can be increased or decreased, and the light emission color and operation mode of the light source can be determined to other light emission colors and operation modes.
