Description

Ink Jet Recording Device with Felt Ink

The present invention relates to an ink jet recording apparatus, and more particularly, to an ink jet recording apparatus to which felt ink is attached to prevent ink ejected upon replacement of an ink cartridge onto the frame base assembly.

In general, recording methods such as wire dot, thermal transfer, ink jet, etc. among the methods of recording an image on paper such as paper or overhead project (OHP) film use a unique recording head. . Among the above recording methods, the ink jet method is a method of recording an image by ejecting ink onto paper. The recording head provided in the recording apparatus employing such an ink jet method includes a plurality of nozzles each having fine ejection holes for ejecting ink. The ink in the nozzles is expanded by the heating of a heating element installed correspondingly to each nozzle one by one and is ejected out of the nozzle. An ink jet recording apparatus records a desired image on paper by selectively driving nozzles while moving the recording head in a horizontal direction corresponding to the image to be recorded.

Hereinafter, an engine mechanism structure of the ink jet recording apparatus will be described with reference to FIGS. 1 and 2.

1 is a front perspective view for explaining the structure of the engine mechanism of a conventional ink jet printer. Referring to FIG. 1, the printer engine includes a line feed mechanism 102, a carriage mechanism 104, a home assembly 106, a friction roller assembly 108 and a carriage. It consists of a motor 116 and a line feed motor, these are assembled to the frame (frame) (100). The line feed mechanism 102 is composed of a frame base assembly 120 and a feed roller 114, as shown in the exploded perspective view of Figure 2, the carriage mechanism 104 to feed the paper from the ASF (not shown) Is transferred toward a recording head (not shown) mounted on the carriage 112. Typically, the recording head is provided as an ink cartridge integrated with the ink container. The ink cartridge is replaceable, and the recording head is provided on the bottom of the ink cartridge so as to face the paper surface. When the paper according to the feeding reaches the contact surface between the feed roller 114 and the friction roller 122 and is inserted, the paper is conveyed toward the recording head by the feed roller 114 rotated by the line feed motor so that the image is recorded. After being discharged to the outside. At this time, whether the paper reaches between the feed roller 114 and the friction roller 122 is detected by a paper sensor consisting of a transmission type optical sensor and the actuator feed 128. The actuator feed 128 is installed directly in front of the feed roller 114 and the friction roller 122, and is pushed by the leading edge of the paper being fed while blocking the optical path between the light emitting element and the light receiving element of the optical sensor. Lose. Accordingly, the light of the light emitting element of the optical sensor is received by the light receiving element to detect that the paper has reached between the feed roller 114 and the friction roller 122. The carriage mechanism 104 then moves the ink cartridge mounted in the carriage 112 horizontally by the carriage motor 116 as described above. At this time, the carriage 112 moves horizontally along the left and right along the carrier shaft 110 installed to extend horizontally. The home assembly 106 also caps the recording head as the carriage 112 is moved to the home position when the printer is not used.

On the other hand, the friction roller assembly 108 is composed of a plurality of sub-assemblies consisting of the friction roller 122, the friction roller guide 124 and the spring 126 in the same manner to closely adhere the paper to the feed roller 114 Let it be. In each sub-assembly, the friction roller 122 is installed on an axis parallel to the feed roller 114 and is in contact with the feed roller 114. One side of the friction roller guide 124 is connected to the friction roller 122 and the other side is connected to the tension spring 126 is fixed to the frame 100. Accordingly, the friction roller guide 124 elastically closes the friction roller 122 to the feed roller 114.

In the conventional ink jet recording apparatus having the engine mechanism configuration as described above, there are only a few grooves 121 at the ink replacement position of the frame base assembly 120, so that the ink ejected when the ink is replaced is transferred to the frame base assembly 120. You will be asked directly. Due to this phenomenon, the frame base assembly 120 is contaminated due to the ejected ink every time the ink cartridge is replaced.

Accordingly, an object of the present invention is to provide an ink jet recording apparatus having felt ink capable of absorbing ink sprayed during replacement of an ink cartridge to prevent contamination of the frame base assembly.

The present invention for achieving the above object is an ink jet recording apparatus,

A hole is formed in the frame base assembly perpendicular to the ink replacement position, and felt ink is attached to the cover burr facing in the vertical direction of the formed hole to absorb the ejected ink.

1 is a front perspective view showing the structure of the engine mechanism of a conventional ink jet printer.

2 is an exploded perspective view of the line feed mechanism and friction roller assembly;

3 is a perspective view of a cover bottom to which a felt ink is attached according to an embodiment of the present invention.

Hereinafter, an operation according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following description and drawings the same components have been given the same reference numerals and many specific details, such as cloth or sponges, cited as the material of the felt ink are shown to provide a general understanding of the subject innovation. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

3 is a perspective view of a cover bottom (118) with a felt ink is attached according to an embodiment of the present invention, a hole 121 in the ink replacement position of the frame base assembly 120, By attaching the felt ink 134 to the cover gap 118 in the downward direction of the perforated hole 121, contamination of the frame base assembly 120 may be prevented when the ink cartridge is replaced. Hereinafter, the frame base assembly 120 according to an embodiment of the present invention will be described in detail with reference to FIG. 3.

First, when the ink replacement button of the printer panel is pressed to replace the ink cartridge of the ink jet printer, the carriage 112 moves to the ink replacement position. The user then has to press the ink replacement button again to replace the ink cartridge and move the carriage 112 back to the home position. In this case, ink must be ejected to check whether the ink cartridge is correctly installed, the color ink is installed or the black ink is installed. Therefore, when the ink is ejected at the ink replacement position, the ejected ink is absorbed by the felt ink 134 attached to the cover gap 118 through the hole 121 drilled at the position where the ink of the frame base assembly 120 is ejected. The user can then check the ink absorbed in the felt ink 134 to identify whether the ink cartridge is correctly mounted or the color of the ink that is mounted. That is, when the ink cartridge is repeatedly replaced in the same printer, the ink ejected due to the felt ink 134 attached to the lower direction of the hole 121 drilled at the ink replacement position of the frame base assembly 120 is injected into the frame base assembly ( 120) can be prevented.

As described above, the present invention has an advantage of preventing ink from being contaminated with ink by injecting ink through the shaped holes in the frame base assembly and absorbing the injected ink into the felt ink.
