Abstract
In a recording apparatus, a charging function is turned on when it is detected that a recording head is capped. It is thereby possible to automatically prevent charging during periods in recording processing when a motor and the recording head are driven.
Claims12
A recording apparatus for performing recording by driving a recording head using electric power supplied from an external power supply or a battery, said recording apparatus comprising:
- a charging circuit for charging the battery using the electric power supplied from the external power supply;
- and
- control means for controlling said charging circuit based on retraction information indicating whether or not the recording head is at a retracted position where recording is not performed.
A method for charging a recording apparatus which performs recording by driving a recording head using electric power supplied from an external power supply or a battery, and which includes a charging circuit for charging the battery using the electric power supplied from the external power supply, said method comprising:
- a control step of controlling the charging circuit based on a result of detecting whether or not the recording head is at a retracted position.
A recording apparatus comprising:
- a recording head;
- a power supply circuit capable of supplying power to the recording apparatus when external power is provided to said power supply, and capable of supplying power to the recording apparatus when power is provided to said power supply from a battery;
- and
- a charging circuit that charges the battery from the external power only when the recording head is capped, and inhibits charging of the battery when the recording head is uncapped.
