Abstract

The present invention in preventing the feeding of copy paper,

A plurality of separation rolls 14 having outer circumferential surfaces formed of a rubber member on both sides of the feed roll 8 are provided, wherein the separation rolls 14 are rotated by the rotation of the shaft 55 to be transferred to the copy paper 16. And the separation roll 14 is symmetrically mutually inclined at a predetermined angle so that the copy paper 33 to be transported next and spaced apart from each other may be prevented in advance. It is to be done.

The present invention relates to a non-feeding device for copier paper, and more particularly, to a non-feeding device for copier paper having rolls on both sides of a feed roll for transferring copy paper for the first time when copying. It is about.

In general, copiers are used at home or office in order to facilitate the convenience of life.

1 is a perspective view showing a general copier.

As shown, the upper part of the copier 88 is roughly provided with a cover 77 and an operation button 66 so as to be functionally performed according to each use. In addition, the front of the copier 88 is provided with a cassette (2) for storing copy paper of different sizes. Therefore, when using the copier 88, pressing the operation button 66 provided on the top of the copier 88, the copy paper (not shown) stored in the cassette 2 is conveyed one by one You can copy it.

2 is a plan view showing a copy paper cassette mounted in a conventional copier, wherein the copier cassette 2 is roughly composed of a cassette case 4 and a plate 6. At this time, the plate 6 is provided in the lower portion of the cassette case 4 and is supported by a compression spring (not shown) to be in contact with the feed roll 8 of the copier 88.

The feed roll 8 is provided with a plurality of shafts 55 connected to a motor (not shown) driven by the application of power.

In addition, it is provided with a snubber 10 and a snubber bracket 12 provided on both sides of the front side of the cassette case 4 so as to separate copy by sheet while transferring the copy paper only in the front direction.

Conventional copier cassettes configured as described above are transported while the copying paper is grounded with the rubber member surrounding the outer circumferential surface of the feed roll which is rotated by the drive of the shaft 55. At this time, copy papers loaded at a predetermined height in the cassette case are sequentially transferred from the top. In this process, the other copy papers directly below the copy papers are closely adhered to each other, so that a plurality of sheets are overlapped and transferred. It was.

Therefore, there is a problem that the paper other than the copy paper to be copied is wrinkled or, in some cases, the paper is torn, resulting in surface damage of the feed roll.

Therefore, the present invention was devised to solve the above problems, and prevents the transport of copy paper so that the copy paper can be separated into sheets on both sides of the feed roll for transporting the copy paper for the first time when the copying machine is used. It is an object to provide a device that can.

In order to achieve the above object, the present invention provides an apparatus for transferring copy paper for the first time when using a copier,

Characterized in that a plurality of separation rolls formed with a rubber member on the outer circumferential surface on both sides of the feed roll.

In addition, the separation roll is formed by the separation roll is inclined at a predetermined angle so that the copy paper to be transported and the copy paper to be transported next to be spaced apart from each other when rotated by the rotation of the shaft, the separation roll provided on the left and right Are arranged symmetrically with each other.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, FIGS. 3 to 5 to realize the above-mentioned objects in detail.

The same parts as those of the prior art components shown in Figs. 1 and 2 are given the same reference numerals, and only differences from the prior art will be described.

Figure 3 is a plan view of the subject innovation, the outer peripheral surface of the rubber member on the feed roll 8, which is provided on the shaft 55 that is rotated by the drive of the motor to prevent the conveying of the copy paper 16 is the same as the conventional rubber member A plurality of separation rolls 14 are provided.

In addition, the separation roll 14 is formed with the separation roll 14 is inclined at a predetermined angle so that the copy paper 16 to be transported and the copy paper 33 to be transported next are transported apart from each other. At this time, the separation rolls 14 provided on both sides of the feed roll 8 are provided symmetrically.

4 is a plan view showing that the contact surface in contact with the copying paper 16 to which the separation roll 14 provided as described above is moved in accordance with the rotation of the separation roll 14. As shown, the copy paper 16 first contacted with the separation roll 14 is mounted on the separation roll 14 at a predetermined angle so that the separation roll 14 simultaneously with the rotation of the shaft 55. As it rotates, the contact surface of the conveyed copy paper 16 changes.

The present invention as described in the accompanying drawings, as shown in FIG. 5, when the copy paper 16 is moved in one direction in contact with the feed roll 8 to be inclined at a predetermined interval on both sides of the feed roll (8) It is conveyed while being grounded to the separation roll 14 formed.

At this time, the separation roll 14 is inclined to face each other so that the first contact point with the copy paper 16 is changed at the same time as the rotation of the separation roll 14, and then the copy paper 16, which is conveyed, is instantaneously transferred to the lower copy paper. Slightly apart from (33). Therefore, the contact force with the next copy paper 33 is weakened so that only the desired copy paper 16 is smoothly conveyed without overlapping at the same time.

As such, the present invention has an effect of preventing the feeding of the copy paper in advance since the separation rolls provided at a predetermined distance from the feed roll are inclined at a predetermined angle when the copy paper is transported.

Claims (2)
