PORTABLE DEVICE AND IMAGE RECORDING DEVICE
First Claim
1. A portable device operated by a rechargeable battery, the portable device comprising:
- a connecting unit configured to connect the portable device and a power supply that supplies a driving current for driving the portable device and a charging current for charging the rechargeable battery;
a detection unit configured to detect a battery voltage of the rechargeable battery; and
a charging control unit configured to control starting and stopping of charging of the rechargeable battery,wherein, when the battery voltage is greater than or equal to a predetermined threshold value, the charging control unit causes the power supply to stop supplying the charging current to the rechargeable battery until the battery voltage becomes less than the predetermined threshold value, andwherein, when the battery voltage is less than the predetermined threshold value, the charging control unit causes the power supply to start supplying the charging current to the rechargeable battery until the rechargeable battery is fully charged.

Abstract
A portable device operated by a rechargeable battery includes a connecting unit that connects the portable device and a power supply that supplies a driving current and a charging current; a detection unit that detects a battery voltage of the rechargeable battery; and a charging control unit that controls starting and stopping of charging of the rechargeable battery. When the battery voltage is greater than a predetermined threshold value, the charging control unit causes the power supply to stop supplying the charging current until the battery voltage becomes less than the predetermined threshold value. When the battery voltage is less than the predetermined threshold value, the charging control unit causes the power supply to start supplying the charging current until the rechargeable battery is fully charged.
