The present invention relates to a paper feed cassette, and more particularly, to a paper feed cassette having a paper fixing guide for guiding and setting a recording paper that can be used in a machine such as a printer, a copier, a fax machine, and the like.

In general, a device such as a printer, a copier, a fax machine, or the like is provided with a paper feed cassette for stacking a plurality of recording sheets. These paper feed cassettes have a single-size cassette for fixing only one size of recording paper, and a universal size that can freely use various sizes of paper by adjusting the loading size according to the size of the recording paper. It is divided into cassettes (Universal Cassette).

The single-size cassette has the advantage that the paper size is fixed according to the size of the recording paper so that the paper can be fed with certainty.However, when using different sizes of paper, the cassette must be replaced. In addition, since separate paper cassettes must be prepared for each size, the total number of paper cassettes increases, and there is a need to secure a place to separately store cassettes used. Therefore, in recent years, there is a tendency to use a universal cassette capable of using recording paper of various sizes as one paper feed cassette.

Referring to FIG. 1, there is shown a general universal paper feed cassette in which a user can move a side guide and a rear guide to adjust and load recording paper for each size.

Conventional universal paper feed cassette is coupled to the case 10, both sides of the case 10 so as to be rotated in the vertical direction by the pin (P), the paper pressing plate 12, the paper pressing plate 12, the recording paper is seated on the upper surface A pair of side guide members 14 installed in the case 10 and a rear end portion of the recording sheet seated on the paper pressing plate 12 so as to slide along the width of the recording sheet while supporting the side ends of the recording sheet seated on the sheet). While being guided by the rear guide member 16 and the side guide member 14 and the rear guide member 16 installed in the case 10 so as to slide along the length of the recording paper, the recording paper seated on the paper pressing plate 12. It is provided with a pair of finger members 17 for crimping and supporting the leading edge portion of the. The lower portion of the paper pressing plate 12 is provided with a spring 18 for pressing the paper pressing plate 12 in the upper direction. In addition, the side guide member 14, the rack 15 is installed, respectively, the pinion (not shown) is engaged between the rack 15 and the side guide member 14 to guide the sliding movement of the side guide member 14. do.

Referring to the operation for accommodating the recording paper of the conventional universal paper cassette configured as described above, first, the side guide members 14 on both sides are sufficiently separated to accommodate the recording paper, and the recording paper is placed on the paper pressing plate 12. Is loaded on. After the recording paper is loaded, the side guide member 14 is moved in the direction of the arrow B to closely hold the recording paper from the side. The rear guide member 16 is also moved in the direction of the arrow A to support the rear end of the recording paper. At this time, the leading end of the recording paper is adjusted to coincide with the leading end of the paper pressing plate 12, and the leading end of the recording paper is adjusted between the paper pressing plate 12 and the finger member 17. The recording paper loaded in this way is made to stand in a state of being pressed against the finger member 17 by the elastic force of the spring 18 provided below the paper pressing plate 12.

Thereafter, in the case of using a different size of paper, the used recording paper is taken out, and the recording paper to be used is placed on the paper pressure plate 12, and the side guide member 14 and the rear guide member 16 are operated in the same manner as described above. Adjust the to load the recording paper.

However, in the conventional universal cassette, the side guide member 14 and the rear guide member 16 are slidably arranged so that the user can easily adjust the size of the recording paper having different sizes so that printing or copying proceeds. As a result, the position of the side guide member 14 and the rear guide member 16 could be easily shifted due to the vibration of the paper feed roller and the force to feed the recording paper, and thus the recording paper could not be firmly supported. . In this case, a problem arises in that the recording paper is fed in a misaligned state and the content to be printed or copied is skewed.

In addition, since the side guide member 14 and the rear guide member 16 are separately configured, the side guide member 14 and the side guide member 14 and the side guide member 14 have not only hassle to adjust separately in the longitudinal direction and the width direction. In order to configure the rear guide member 16 to be slidable, complicated components such as racks and pinions have to be installed, thereby increasing the number of parts for manufacturing the paper feed cassette, thereby increasing the manufacturing cost.
