Description

Paper guide fixing unit of paper cassette

The present invention relates to a paper cassette in which a plurality of sheets are fed in an electrophotographic processor using an electrophotographic developing method including a printer, a copying machine, and a laser beam printer. In particular, the paper is set by adjusting the width of the sheet. It relates to a fixing device of the paper guide.

1 is a perspective view showing a paper cassette according to a conventional embodiment. 2 is a cross-sectional view showing a paper guide according to a conventional embodiment. As shown in FIG. 1,

The paper feed cassette 200 is a place where a plurality of sheets are loaded, and serves to provide a force to hold the paper loaded by the paper support 210 and the elastic means installed under the paper support in the pickup position. In addition, a paper guide 100 corresponding to various paper widths is installed, and the paper guide 100 for setting the paper corresponding to the paper width should be designed according to the width or length of the paper due to the variety of paper. In case of setting, the paper guide 100 should be designed to move back and forth, and to be fixed while moving smoothly. In addition, no flow should occur when picking up the paper after setting the paper, and it should be configured to be easily operated by the user.

As shown in FIG. 2, the conventional paper guide 100 has a tension unit 120 having a tension protrusion 130 on one side thereof, and a tension hole 110 corresponding to the tension unit 120. The tension protrusion 130 is slightly movable up and down due to the characteristics of the material, the end is formed in a curved surface, it is possible to forcibly move the hole in the bottom of the paper cassette.

However, the above paper guide has the following problems.

Conventional paper guides are inconvenient to be moved by the user by force. Moreover, such a paper guide has a problem that the tension applied to the left and right by the longitudinal direction of the paper is large, or is affected by the size of the paper. Due to this problem, fixing the paper guide is not easy.

The present invention is devised to solve the above-described problems, the object of the present invention is to provide a paper guide fixing device that is easily fixed, easily released.

In order to achieve the above objects, the present invention is a paper guide fixing device of the paper cassette, the paper guide having a first hinge protruding to face each other on both sides of the rear bottom surface, and the hinge hole inserted into the first hinge The provided hinge arm is formed to face the rear, and the hinge arm having a hinge hole in the front is provided to face each other, the fixing protrusion protrudes in the center of the bottom, and is assembled to the paper guide to be rotatable about the first hinge axis. The lock guide, a handle coupled to the front hinge arm of the lock guide, and a tension coil spring provided between the paper guide and the handle to provide a force for returning the handle to its original position. Is inserted and fixed.

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.

Figure 3 is a perspective view showing a paper guide fixing device according to an embodiment of the present invention. 4 is a cross-sectional view showing a paper guide of the present invention is installed paper feed cassette.

Paper guides for setting paper corresponding to paper width should be designed according to the width or length of paper due to the variety of paper. When setting paper, the paper guide should be designed to move back and forth and left and right. Should be fixed. In addition, no flow should occur when picking up the paper after setting the paper, and it should be configured to be easily operated by the user.

The paper guide fixing device of the present invention includes a paper guide 10, a lock guide 30 assembled to the paper guide, a handle 20 assembled to the lock guide, and a tension coil spring 40 installed between the paper guide 10 and the handle 20. It consists of.

The paper guide 10 has a first hinge 11 protruding from both sides of the rear inner surface to be coupled to the lock guide 30, and hinge arms 31 corresponding to the hinge 11 are formed at both ends of the lock guide rear. The hinge arm 31 is formed with a hinge hole 32 into which the first hinge 11 is inserted. In addition, the second hinge 21 protrudes on both sides of the lower end of the handle so that the handle 20 is assembled with the lock guide 30, and hinge arms 33 corresponding to the second hinge 2 are formed on both sides of the front of the lock guide.

In addition, fixing parts 22 and 12 protrude from the tension coil spring 40 so as to be installed between the handle 20 and the paper guide 10. The upper end of the tension coil spring 40 is fixed to the fixing part 22 of the handle, and the lower end of the tension coil spring 40 is fixed to the fixing part 12 of the paper guide.

In the assembly state as described above, the lock guide 30 is rotatable about the first hinge 11, and the handle 20 is rotatable about the second hinge 21.

At this time, the bottom surface of the lock guide 30 is inserted into or removed from the hole 51 of the paper feed cassette 50, so that a protrusion 54 for maintaining the fixed state of the paper guide 10 is formed.

In order to move the paper guide 10 in the direction of the arrow, the user first lifts the handle 20 upward. At this time, since the elastic coil is provided by the tension coil spring 40, it is in a state of receiving a force to return to its original position. Since it is coupled to the handle 20 by the second hinge 21, it moves upward together, and the lock guide 30 rotates about the first hinge shaft 11. The rotational movement of the lock guide 30 is limited. At the same time, the fixing projection 34 is released from the hole 51 of the paper feed cassette, so that the paper guide 10 is free. The user can move the paper guides.

When the force applied is removed after setting the paper guide 10 corresponding to the width of the paper, the handle 20 is moved downward by the tension coil spring 40, and simultaneously the lock guide 30 is lowered about the second hinge axis 21. Rotate to return to home position. At this time, since the fixing protrusion 34 of the lock guide 30 is inserted into the hole 51, the paper guide 10 is fixed.

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 convenient for fixing the paper guide of the paper feed cassette from the user's point of view. Also, it appropriately corresponds to various paper sizes.
