Below, the flash-over characteristic of above-mentioned battery supply and the condition of extremely knowing the inside story of battery remaining amount are described.

Figure 39 (a) is the current sinking one discharging voltage characteristic ideograph regularly that the discharging current of battery promptly installs.As shown in the figure, beginning, cell voltage remains rated value basically, and as time passes, voltage begins to land lentamente, descends sharp at last.

Consider such discharging voltage characteristic, utilize the voltage setting circuit of voltage monitor 133, set the voltage level of warning battery capacity to reduce to the user.

Figure 39 (b) is the discharging voltage characteristic ideograph of the discharging current of battery when changing.

The current sinking of picture unit during, when transmission, operate condition and different, in addition, also different such as when accepting, when duplicating with the kind of original copy with standby.Therefore, shown in Figure 39 (b), even battery also has residual volume, if increase load suddenly, cell voltage will reduce.Here, if less than the warning voltage of setting by the voltage setting circuit of voltage monitor 133, owing to also have battery capacity that LED134 is flashed.So cell voltage can rise once more, LED134 stops flash of light, becomes always and lights.

After action continued to use usually, during once more less than warning voltage, LED134 began again to flash.At this moment, because battery allowance seldom, so cell voltage no longer rises, LED134 glistens always, warns to the user.

Like this, just can urge the user to charge the battery to the user notification battery consumption.

In above the 1st embodiment, be to utilize the flash of light of LED134 to notify battery consumption, still, also can notify with buzzing sound.This can be in above-mentioned structure shown in Figure 1, utilizes the output signal of voltage monitor 133 to drive buzzer 131 and realizes.At this moment, can not need LED134 in the main body structure.

Figure 40 (a) and (b) are ideographs of reporting action of the flash-over characteristic and the residual amount of battery of battery supply.Except flash of light, identical with the action shown in above-mentioned Figure 39 (a) and (b) with the above-mentioned LED134 of buzzing sound-substitution of buzzer.

In addition, in the present embodiment, LED134 is specifically designed to the residual amount of battery of reporting, still, also can represents the demonstration usefulness of energized with the LED double as.

Figure 41 (a) and (b) are that the residual amount of flash-over characteristic, battery that battery supply at this moment is described is reported the ideograph that shows with power supply.

Figure 41 (a) is discharging current one discharging voltage characteristic regularly of battery, and is identical with the foregoing description, beginning, and cell voltage keeps rated value basically, and As time goes on, voltage begins to reduce lentamente, reduces sharp at last.

Consider such discharging voltage characteristic, utilize the voltage setting circuit of voltage monitor 133, set the voltage level that shows the demonstration warning battery consumption that is converted to LED134 generation flash of light from the power supply of lighting continuously of LED134.

Figure 41 (b) be the discharging current of battery when changing discharging voltage characteristic and monitor the ideograph of LED drive waveforms of the voltage monitor 133 of this discharging voltage characteristic.

Under common user mode, when cell voltage is very high, utilize voltage monitor 133 to make LED134 remain continuous illuminating state.When load increase suddenly, cell voltage reduction, as if the warning voltage of setting less than the voltage setting circuit of voltage monitor 133, then LED134 flashes.But owing to also have battery capacity, so cell voltage can rise once more, LED134 stops flash of light, and becomes lasting illuminating state.

After continuing the use of action usually, cell voltage is during once more less than warning voltage, and LED134 begins to glisten.At this moment, because the residual amount of battery seldom, so cell voltage no longer rises, LED134 glistens always, warns to the user.

Therefore, drive output as can be known by the LED shown in the bottom of Figure 41 (b), the state of LED134 remains " 1 " greater than warning voltage the time, driving LED 134 is lighted, and during less than warning voltage, the state of LED134 is " 0 " repeatedly, " 1 ", driving LED 134 is glistened.
