PURPOSE:To obtain a power supply prevented from the disconnection of power supply voltage at the replacement of a battery by connecting a diode to each battery in parallel in the reverse bias direction. CONSTITUTION:The dry batteries 201-204 are connected in series and diodes 205-208 are connected to respective batteries in parallel in the reverse bias direction to obtain about 6V power supply voltage. Even if the battery 202 is removed, the battery 201 is connected with the battery 203 by the diode 206, so that about 4.5V power supply voltage can be generated. If each battery is removed and replaced by a new one repeatedly at the replacement of batteries, about 4V or more power supply voltage can be maintained. |
