The present invention concerns an ink jet unit detachably mounted to the carriage of an ink jet recording apparatus. The ink jet unit includes an ink container for storing ink and a casing for retaining the ink container, wherein the casing and ink container are independent from each other so that the ink container can be exchangeably installed in the casing. The casing includes an ink jet recording portion, an opening for mounting the ink container thereto, a guide portion for installing the ink container into an accommodating portion through a rotary motion, a shoe portion generating a resistive feel when the ink container is inserted into the accommodating portion, and a dislocation preventive member. The shoe portion has a pressing device for maintaining fluid communication between the ink container and an ink supply tube contained in the casing.

Ink container, installing-removing method therefore and apparatus usable with the same

A mounting method of an ink container to an ink jet unit mountable to an ink jet recording apparatus, wherein the ink container is mounted while a corner portion of the ink container between a top surface and a rear side is slid in contact with an urging member and while a corner portion of the ink container between a front side and a bottom side is slid toward a front side of the ink jet unit in contact with an inner bottom surface of the ink jet unit.

Method of mounting an exchangeable ink container

An ink jet unit to which an ink container is detachably mountable, and which is further mountable to an ink jet recording apparatus so as to effect ink jet recording. The ink jet unit includes an ink jet head for ejecting ink for recording, an ink supply tube for receiving ink from the ink container and being provided at a bottom portion of the ink jet unit in fluid communication with the ink jet head, and an opening for permitting mounting of the ink container thereto. The opening is formed continuously, in such sides of the ink jet unit as take top and front positions when the ink jet unit is mounted to the ink jet recording apparatus. A cover is provided, at the top side of the ink jet unit. The cover includes at an inside thereof a substantially non-elastic material provided at least at an inner corner between the top side and a rear side of the ink jet unit, and further includes an inclined portion which increases resistance against insertion of the ink container through the opening during mounting of the ink container as well as a substantially horizontal portion, all for urging the ink container downwardly to mount the ink container for fluid communication with the ink supply tube.

Ink jet unit for a detachably mountable ink container

An ink filling method in which ink is filled to an ink container provided with a porous material for retaining the ink to be supplied to a head portion for ejecting the ink and a container casing for accommodating the porous material, including the steps of compressing the porous material accommodated in the container casing, and filling the ink using restoring force of the porous material when it is released from compression state

Ink cartridge for printer

An ink container cartridge detachably mountable to an ink jet recording head, includes a main body of ink container cartridge; an ink retaining member, in the main body, for retaining the ink; wherein the ink retaining member is contained in the ink container cartridge so that a compression ratio A of the ink retaining member by a side having an ink supply opening of the ink container cartridge and a side opposite therefrom, and a compression ratio B by other two opposite sides thereof, satisfy A&gt;B, and 1.1.ltoreq.A.ltoreq.1.6.

Ink container cartridge

A film-forming apparatus is provided with a particle prevention means, whose structure prevents a drop in film-yield due to particle formation. The particle prevention means does not need to be cleaned as frequently as known particle prevention means, thus increasing film production efficiency. This particle prevention means has a tongued-and-grooved surface. When the particle prevention means having a tongued-and-grooved surface is set in the film-forming apparatus, the film-forming material is deposited in a discontinuous manner on the particle prevention means, which can extend the time of film exfoliation, and in turn, extend the cycle for cleaning the particle prevention means, and prevent a drop in film-yield due to the film exfoliation.

Film forming apparatus with particle prevention plate

An ink jet recording apparatus includes a recording head having plural discharge openings for discharging ink, a liquid chamber for storing the ink to be supplied to the discharge openings, a liquid flow path for communicating the discharge openings with the liquid chamber, and plural energy generating elements for generating energy to be used for discharging the ink from the discharge openings. The head also includes a substrate having the energy generating elements provided thereon and a transfer molded structural member made of thermosetting resin. The structural member has a concave portion for forming a liquid flow path, and the structural member is fused to the substrate.
