Printhead chip incorporating double action shutter mechanisms |
摘要 |
A printhead chip includes a substrate that incorporates a drive circuitry layer and defines a plurality of ink inlet channels. A plurality of nozzle chamber structures is positioned on the substrate. Each nozzle chamber structure defines a nozzle chamber and an ink ejection port in fluid communication with the nozzle chamber. The nozzle chambers are in fluid communication with respective ink inlet channels. A plurality of shutter members is positioned in respective nozzle chambers. Each shutter member is displaceable in a plane substantially parallel to the substrate between a closed position in which the shutter member closes the respective ink inlet channel and an open position in which ink is permitted to flow into the respective nozzle chamber. A plurality of actuating mechanisms is connected to the drive circuitry layer and the respective shutter members to displace the shutter members between the open and closed positions on receipt of a signal from the drive circuitry layer.
