| 发明名称 | Apparatus for charging power storage unit provided in carriage having printhead, and charge control method and storage medium storing program thereof | ||
| 摘要 | An apparatus including: a control unit configured to control a switch that performs switching between a charging path for charging a first power storage unit provided in a carriage having a printhead mounted thereon by power supplied from a power source and a charging path for charging the first power storage unit by power supplied from a second power storage unit that is provided in a main body of the printing apparatus equipped with the carriage and has a capacity higher than the first power storage unit; and a determining unit configured to determine whether or not the second power storage unit has a power storage capacity less than a threshold value, wherein the control unit controls the switch such that the first power storage unit can be charged by the power supplied from the power source if it is determined by the determining unit that the power storage capacity of the second power storage unit is less than the threshold value. | ||

| 主权项 | 1. An apparatus comprising: a control unit configured to control a switch that performs switching between a charging path for charging a first power storage unit provided in a carriage having a printhead mounted thereon by power supplied from a power source and a charging path for charging the first power storage unit by power supplied from a second power storage unit that is provided in a main body of a printing apparatus equipped with the carriage and has a capacity higher than the first power storage unit; and a determining unit configured to determine whether or not the second power storage unit has a power storage capacity less than a threshold value, wherein the control unit controls the switch such that the first power storage unit can be charged by the power supplied from the power source if it is determined by the determining unit that the power storage capacity of the second power storage unit is less than the threshold value. | ||
