Cradle for printhead cartridge having power storage interface
View Patent ↗A cradle unit for a printhead cartridge, the cradle unit comprising: an interface at which the cradle unit is removably engageable with a printhead cartridge, the interface comprising connections for connecting the printhead cartridge with a power supply which is remote from the interface; and a power storage circuit incorporated in the interface for storing at least some of the power being supplied to the printhead cartridge from the power supply.
1. A cradle unit for a printhead cartridge, the cradle unit comprising:
a support bay for removably receiving the printhead cartridge;
an interface mounted on a slanted face within the support bay, the interface comprising connections which are movably tilted on said slanted face so as to be exposed within the support bay for connection with connections of the printhead cartridge when received in the support bay, the connections of the interface connecting the printhead cartridge with a power supply which is remote from the interface; and
a power storage circuit incorporated in the interface for storing at least some of the power being supplied to the printhead cartridge from the power supply.
2. A cradle unit according to claim 1 , wherein the interface incorporates a first printed circuit board, the connections and power storage circuit being arranged on the first printed circuit board.
3. A cradle unit according to claim 2 , wherein the connections of the interface are arranged to connect the printhead cartridge with print control circuitry of the cradle unit.
4. A cradle unit according to claim 3 , wherein the print control circuitry is incorporated on a second printed circuit board, the first and second printed circuit boards having complementary connectors which cooperate to provide the connection of the printhead cartridge and print control circuitry.
5. A cradle unit according to claim 4 , wherein the first printed circuit board is arranged so as to substantially orthogonally project from the second printed circuit through the cooperation of the complementary connectors.
6. A cradle unit according to claim 5 , wherein the complementary connectors are arranged so that the first printed circuit board is able to pivot with respect to the second printed circuit board.
