摘要： An ink-jet printer includes an ink-jet head assembly which has a modular structure. The head assembly includes a generally bathtub-shaped bottom case in which an ink head for ejecting a series of charged ink droplets is mounted and a pair of top and bottom deflection electrodes is also mounted. The head assembly also includes a similarly bathtub-shaped top case which is mounted on the bottom case upside down to define a substantially enclosed space therebetween. The ink head is supported so as to be adjustable in orientation. And, one end of the ink head is supported as a pivotal point so that the other free end may be oriented in any desired direction. In another structure, a print head assembly is detachably mounted on a carriage and the print head assembly includes an inner ink mist absorbing member formed with a slit and formed from a metal. A carriage cover is detachably mounted on the carriage to cover the print head assembly set in position. The carriage cover is provided with an outer ink mist absorbing member formed with a slit and formed from a resin material.

摘要： An apparatus for removing air from ink which is fed under pressure to a nozzle of an ink ejection head is disclosed. A first solenoid-operated valve is disposed between an ink pressurizing source and the nozzle. Located between the valve and the nozzle is a deaerating unit which has therein a bore for causing air entrained by the ink to surface. An air outlet is formed in an upper portion of the bore and opened and closed by a second solenoid-operated valve. Upon a stop of ink ejection, the first valve is closed (ink supply blocked) while the second valve is opened. Heaters are installed in the bore of the deaerating unit to heat ink inside the bore to a predetermined temperature, so that air in the ink is expanded to become readily separable from the ink.

摘要： In an ink jet printing apparatus wherein an ink ejection head is loaded on a carriage and, while the carriage moves relative to a sheet of paper, ink droplets are ejected from the head to be charged and deflected to impinge on the sheet of paper, a shape or a position of a conductive member carried on the carriage is varied to develop an electric field which is asymmetrical with respect to a predetermined plane in which charged ink droplets coming out from a charging electrode are to be deflected. The conductive member is constituted by a cover of the carriage, a shield plate, a gutter, a compensating electrode plate, a deflection electrode or the like.

摘要： An ink mist collection apparatus for an ink jet printer comprises an ink mist adsorptive member interposed between a paper sheet and an ink jet head in order to adsorb an ink mist which is produced by an ink droplet ejected from the ink jet head upon impingement of the ink droplet on the paper sheet. The adsorptive member may be made up of a first adsorptive member and a second adsorptive member. The first member is disposed between the paper sheet and deflection electrodes to adsorb an ink mist while the second member is held in contact with the first member. The adsorptive member may be detachably mounted on a guide member which is located between the paper sheet and the ink jet head. The front end of the guide member adjacent to the paper sheet is protruded beyond the front end of the adsorptive member. The adsorptive member on the guide member may have its front surface spaced from the paper sheet more at its intermediate portion than at its opposite end portions.

摘要： A device incorporated in an electrophotographic image recorder for collecting toner particles, paper dust and so on which are removed from a photoconductive element by a cleaning device. The collecting device is constructed independently of the cleaning device. In a portion where the collecting device and cleaning device are connected to each other, a first and a second shutter which open and close respectively an opening formed through the cleaning device and an opening formed through the collecting device cooperate with each other. When the collecting device is connected to the cleaning device, the second shutter unblocks the associated opening before the first shutter does so. Conversely, when the collecting device is disconnected from the cleaning device, the second shutter blocks the associated opening after the first shutter has done so.

摘要： A charge detecting electrode unit is disclosed which is coupled to a platen shaft of an ink jet printer so as to be rotatable relative thereto for detecting a deflected position of charged ink particles. It includes a housing having an internal space in which a charge detecting electrode is centrally located. The housing is formed with an opening which receives flying ink particles, in its front surface. An electrically conductive layer is formed on and continuously extends across the internal wall surfaces and the external surface of the housing around the opening, and an electrically conductive and water absorbing sheet is attached to the outer periphery of the housing and is in contact with the conductive layer located around the opening which is connected to a grounding wire. The housing also includes a compartment which houses a water absorbing pad and which is open to the exterior of the housing. The water absorbing sheet extends into the compartment, and the pad housed within the compartment is in contact with the sheet. The compartment is normally closed by a closure. An isolating plate is disposed in the opening to divide it into an upper and a lower area, thus preventing an ink which has found its way into the lower area from being dispersed into the upper area.
