Description

Auxiliary Paper Support of Automatic Paper Feeder

The present invention relates to an inkjet printer, and more particularly, to an auxiliary paper support of an automatic paper feeder.

Inkjet printers are typically one of the representative computer peripherals for outputting computer data. Ink cartridges, which are disposable consumables, are used as the most economical computer peripheral because they are easy to replace, inexpensive, and advantageous for miniaturization.

The ink cartridge, which is a disposable consumable and detachable from the carriage, is filled with ink, the print head is installed, and ink is transferred to the paper through the nozzle hole using pressure and heat. The printing process is performed by spraying.

1 is a perspective view showing an automatic paper feeder ASF of a conventional inkjet printer, Figure 2 is a perspective view showing an auxiliary paper support according to a conventional embodiment.

As shown in Figures 1 and 2, the auxiliary paper support 720 is installed between the frame 700 and the rear of the knock-up plate 710 in the automatic paper feeder ASF. The paper support 720 is immersed. When not in use, the paper support 720 stays immersed and, if necessary, is exposed. The paper support 720 uses a sliding method that is extended or immersed.

As shown in FIG. 2, in the conventional auxiliary paper support 720, the first tension holes 722 are formed in parallel in the longitudinal direction, and the pedestals have the same elastic force by the tension holes 722. In addition, a tension portion 726 is formed by forming a second tension hole 724 at an end portion thereof. The tension unit 726 is formed to face two. An end portion of the tension portion 726 is formed with a semicircular cross section to provide a force to a corresponding contact surface (bottom surface of the knock-up plate). Accordingly, the paper support 720 may be removed as much as desired by being separated or inserted into a surface or groove corresponding to the protrusion, or may be kept in a locked state when not needed.

However, the above-mentioned elongated or submerged paper support should be in charge of a very useful function from the point of view of the user who actually uses the inkjet printer, but it has become an indisputable structural element that is rarely used.

That is, the user rarely operates the paper support, and has been using the fixed paper support state as it is until the product is shipped and the user first encounters the device.

Due to this problem, the installation of a paper tray of a separate complicated structure becomes very unnecessary, and for this reason, only the burden on manufacturing costs is added.

This structure has become one of the factors against the miniaturization of products.

The present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is to provide a secondary paper support with a simple structure, reducing the manufacturing cost.

Another object of the present invention is to provide a fixed auxiliary paper support.

In order to achieve the above objects, the present invention projects a guide having a shape corresponding to the auxiliary paper support on the bottom of the paper support, and the auxiliary paper support is fixedly detachable by the guide.

Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention. First, in describing each of the drawings, only the same components have the same reference numerals as much as possible even if shown on different drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

3 is a front perspective view showing a state in which an auxiliary paper support is installed in the paper feeding device ASF of the inkjet printer according to an embodiment of the present invention. Figure 4 is a rear partial perspective view showing the mounting state of the auxiliary paper support according to an embodiment of the present invention. Referring to Figure 3,

Generally, the automatic paper feeder ASF is essentially provided with a paper feed roller assembly 30, a guide 40 for adjusting the paper width, and an auxiliary paper support 20.

At this time, the paper support 10 of the present invention is formed integrally with the automatic paper feeder of the inkjet printer. The existing knock-up plate is moved around the axis, but the paper support 10 of the present invention is a fixed type. In addition, although the conventional movement in the sliding movement to enable the infiltration or extension, the auxiliary paper support 20 of the present invention is fixed to the rear of the paper support 10.

As shown in FIG. 4, in order for the auxiliary paper support 20 to be fixedly installed on the paper support 10, a guide 12 corresponding to the shape of the auxiliary paper support 20 protrudes parallel to the bottom of the paper support 10. By this, the auxiliary paper support 20 is fixed. The guide 12 extends in the vertical direction. The locking jaw 14 protrudes from the upper end of the guide 12. Therefore, when the auxiliary paper support 20 is inserted into and fixed to the guide 12, the auxiliary paper support is not moved back and forth by the locking step 14. In addition, the auxiliary pedestal 20 has an elastic force because it is a plastic material,

In addition, if not necessary, the auxiliary paper support is separated from the main body in the direction of the arrow.

On the other hand, in the detailed description of the present invention has been described with respect to specific embodiments, it will be apparent to those skilled in the art that various modifications are possible without departing from the scope of the present invention.

As described above, the present invention is fixed by installing the auxiliary paper support in the automatic paper feeder of the inkjet printer, the structure is simple, cost reduction, it is advantageous in miniaturization.
