摘要： An ink jet recorder includes a recording head having an ejection nozzle, and a purging apparatus for recovering the ejecting condition of the nozzle. The recorder further includes a timer for clocking the time having passed after the last purging by the purging apparatus, and a controller for controlling the head and the purging apparatus. If a command for operating the head is input in the recorder, and on condition the time clocked by the timer exceeds a predetermined time period, the controller starts the head ejecting ink. The air bubbles produced in the head by purging can vanish naturally during the predetermined period. It is therefore possible to improve the ejecting characteristic and secure high recording quality.

摘要： An ink jet recorder includes a recording head having an actuator for ejecting ink from a nozzle by changing the volume of an ink passage, an ink cartridge, a purging device, and a control unit. The control unit controls the purging device so as to effect a first purge and a second purge having a greater sucking force than that in the first purge, and controls the actuator during the first purging operation. Ink passage walls and ink are vibrated, and by virtue of a synergistic effect with the flow of ink flowing due to the first purging operation, bubbles and foreign objects attached to the passage walls are easily separated from the walls. The operation of the actuator can be executed by lagging behind a purging start for a predetermined time duration.

摘要： A device for driving a recording head comprises select data input elements, a waveform signal selector, and a drive signal supplier. To the select data input elements, select data sets corresponding to recording elements included in the recording head are inputted in a serial manner. Each one of the select data sets indicates which one among waveform signals is to be employed for a corresponding recording element in a single printing cycle. The waveform signal selector selects, for each of the recording elements, one among the waveform signals on the basis of a corresponding one among the select data sets inputted to the select data input. The drive signal supplier supplies, based on the selected waveform signal, a drive signal to each of the recording elements. The number of the select data input elements is greater than the number of bits included in each of the select data sets. The number of signal lines through which the select data sets are inputted to the select data input elements in a serial manner is the same as the number of the select data input elements.

摘要： In a switch provided in a driver device and connected to a driver, a terminal and a lever is separated from each other (in the separated state) when a predetermined electric potential is not applied to a gate electrode. When a predetermined electric potential is applied to the gate electrode, the lever of the corresponding switch is deformed by electrostatic force between the gate electrode and the lever and comes into contact with the terminal, and thus the terminals are connected with the lever (in the contact state). A plurality of drivers are connected to the terminals of two or more of switches, respectively, and, when a driving potential is outputted from a driver, the driving potential is applied to a surface individual electrode connected to the switch in the contact state.

摘要： A plurality of lands and a plurality of conducting wires connected independently to each land are formed on one side surface of an insulating substrate of a flexible printed circuit board. Through-holes are formed through the insulating substrate for exposing the lands to the other side surface. Solder is provided in the through-holes. The solder connects the lands to the head terminals on an inkjet head, which is located facing the other side surface of the insulating substrate. The insulating substrate separates the solder from areas between the conducting wires and from areas between the lands, thereby preventing short circuits from occurring when manufacturing the connecting structure with a low tolerance grade.
