摘要:
An ink jet printer includes a print head having a plurality of piezoelectric driving elements selectively energizable to cause ejection of droplets of ink through nozzles in a nozzle plate. Ink is supplied to the print head from an ink reservoir which is connected to a bellows device. The ink reservoir and the bellows device together form an air-tight container. The bellows device has a resilient form of construction so as to tend to increase the volume of the container. As a result, an appropriate underpressure is maintained in respect of the ink in the nozzles, such underpressure being necessary to prevent ink escaping from the nozzles under quiescent conditions. In operation, the bellows device progressively collapses so as to reduce the rate at which the underpressure increases as ink is ejected, thereby prolonging the period for which the underpressure is maintained within a desired operating range. In two other embodiments, the reservoir is enclosed by a piston or a membrane, both biased against collapse by a compression spring. In yet another embodiment, underpressure within the reservoir is maintained by a capillary tube that at one end is immersed in ink and at the other end is open to the exterior of the printer.

Printing of characters in non-impact manner by means of ink droplets which are driven through the nozzle of an inking device is optically sensed and the existence, the position, the size and the condition of each ink spot or mark are determined. The desired printing signals are generated and input in a signal shaping circuit and these signals are compared with the actual signals from the optical sensor and the ink droplet drive means is changed or altered to correct the printing.
摘要:
Means for supplying ink to a plurality of individually-spaced movable print heads is caused to be moved in a direction therewith but which ink supply means is positioned and directed in a manner perpendicular to the direction of movement of the print heads. An ink container is fixed at a distance from the print heads and a separate flexible ink supply tube, extending substantially in a vertical direction, connects the container with each individual print head. The ink supply tubes are movably swung or pivoted as the print heads are caused to be laterally moved and the swinging or pivoting movement of the supply tubes prevents interruption of the flow of ink to the print heads upon reversal of travel thereof at the ends of the printing lines.
