摘要:
A liquid ejection recording apparatus has a carriage, a liquid ejection recording unit, a lever biased by a spring for mounting the unit on the carriage, and a communication hole portion formed in an ink tank in the unit. When the unit is fixed on the carriage for printing, a projection presses the communication hole portion to provide a communication hole for communicating the interior of the ink tank with the outer atmosphere. Stable ink ejection is guaranteed without clogging of a nozzle or the like and regardless of the amount of ink remaining in the ink tank.

This invention provides a nozzle-restoring suction device provided with a suction unit for generating a negative pressure, a capping unit provided with closing caps for tightly closing respective nozzles formed on a recording head, and a connection unit for connecting the suction unit with the capping unit for enabling suction of the front ends of the nozzles by means of the negative pressure generated in the suction unit.
摘要:
An ink jet type recording apparatus is disclosed which comprises a carriage slide movable along a shaft, a recording head for jetting recording liquid in response to an electric signal, a subsidiary container for supplying the recording liquid to the recording head and a main container connected with the subsidiary container through a flexible supply line. The subsidiary container and recording head are mounted on the carriage. Supply of the recording liquid to the subsidiary container from the main container is carried out making use of the space under the shaft along which the carriage is slide moved.
摘要:
An ink jet apparatus comprises an ink jet nozzle, a cap capable of fitting said ink jet nozzle, and a suction means for supplying negative pressure to the ink jet nozzle and a ink-storage vessel in communication with said ink jet nozzle, characterized in that the suction means is provided with at least two independent suction chambers, with at least one of the suction chambers being in communication with the ink-storage vessel, and with at least the other suction chamber being in communication with the cap.
摘要:
There is an ink jet printer in which an electrostriction element is associated with at least a part of an ink chamber for causing ink emission from an ink nozzle connected to said ink chamber in response to a voltage applied to the electrostriction element. Said voltage is changed in response to the ambient temperature and made higher or lower respectively in a low or high temperature.

The present invention provides a liquid jet recording apparatus, comprising: an open/close means arranged in an ink supply path supplying ink to a discharge opening of a recording head, for permitting and blocking the communicaiton between the ink supply path and the discharge opening; an absorption recovering device for absorbing the ink from the discharge opening by a negative pressure; and a control means for controlling the open/close means in accordance with absorption modes of the absorption recovering device.
摘要:
An ink jet recovery device comprises an elastic cap that is movable between a retracted position, in which it is spaced from a recording head, and a contact position, in which it is pressed against and seals the recording head. The recovery device also includes a rotatable drive gear having a cam surface, with a retracting cam and a compression cam, for moving the cap. When the drive gear is in a first angular position the retracting cam moves the cap to its retracted position, and when the drive gear is in a second angular position the compression cam presses the cap against the recording head. The drive gear has a third angular position for disengaging the pin from the cam surface so that a spring can press the cap into the contact position. In operation, the compression cam further presses the cap toward the recording in order to force air into the recording head to aid recovery.
摘要:
An ink-jet printer has a tank holding ink therein, an ink-jet printing head for printing on a paper sheet, an ink cartridge for holding a supply ink, electrodes for detecting an ink level in the tank, a feeder for feeding the ink in the ink cartridge to the tank when the electrodes detect that the ink level in the tank is below a predetermined level, a timer circuit for allowing the feeder to supply an extra amount of ink to the tank even after the ink level reaches a normal level, and a warning device for warning the operator if the ink level is not recovered to the normal level within a predetermined period of time after the feeder is operated.
