Abstract

PURPOSE:To feed a sheet while maintaining specific position and direction, by providing a rising guide extending in feeding direction of sheet and means for entirely shifting the sheet material to the direction of rising guide. CONSTITUTION:A manual feed paper casset 10 has one end section A to be mounted in an opening made in the body of copier, where many ridges 1b are projected from the surface of cover 1 while a guide 1a is rising from one side. Here, said ridges 1b are extended in the direction to approach to the guide 1a when viewed in advancing direction of sheet. The manually fed sheet is guided by many ridges 1b and shifted automatically toward said guide 1a. Consequently, it is not required to place the sheet along the guide 1a resulting in facilitation of feeding while maintaining specific position and direction.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a manual feeding guide suitable for use in copying machines, blinkers, etc.

When forming a single image using a copying machine, etc., a large number of sets of cassettes and other cassettes for forming an image group are stored in each case. It is normal to take out this material in sequence according to the 8 pulls, but sometimes the size of the sheet material stored in a cassette etc. is different.

I thought about using a few sheets with different thicknesses, t;, i, , l history, so that I could process this notebook with one manual feed. It's normal.

In recent years, copiers and printers have become increasingly smaller.

They are becoming more and more compact, and in small copy machines and the like, transfer paper is used so much that a large amount of paper of a certain size is always stored in a cassette. In addition, printers have been proposed in which the paper feed cassette is set outside the device and the lid of this cassette is used as a guide when manually feeding paper.

As devices become more compact, the ways in which they are used by their users become more diverse.As the size of the sheet material cannot be reduced, it is inevitable that when a cassette 1- is used, it will protrude from the main body of the device. To avoid this problem, there has been a significant increase in the need for manual feeding mechanisms to be simple and reliable.

However, although it is natural that a notebook for image formation must be fed to an accurate position within an image forming apparatus, it is difficult for a user to manually feed a sheet from outside the apparatus. Of course, it tends to be accurate, and this causes skewing of the sheet, sheet l
It was not easy to prevent troubles such as damage to the 7-1-1. In order to avoid the above-mentioned drawbacks due to the planar arrangement, there are two functions: one to propel the sheet to be fed in the direction of the lateral end face of the sheet to be fed, and the other to advance it in the original sheet feeding direction. Manual paper feeding had to be done carefully and carefully because it was necessary to make a directional effect.

The present invention eliminates such cumbersome handling when manually feeding paper, and allows individual users to: 1. To provide a feeding kite that can be easily and reliably carried out without any problems.

The present invention will be described below with reference to an embodiment that takes advantage of differences in cassettes I and I used in image forming apparatuses.

FIG. 1 is a perspective view showing a well-known cassette in which a paper feed kite is formed with a cover positioned opposite to an opening BY for inserting a cassette provided in the main body 13 of a copying machine or the like; When the cassette 10 is inserted into the opening 1-31, the cassette is inserted IDζ into the main body 13 and is held approximately up to the portion indicated by the line XX in the figure. Is it the sheet stored in the cassette 10 that activates the copying machine, etc.]
Whether the sheet is supplied into the main body while the image forming operation is being carried out or not is not directly related to the present invention, so a description thereof will be omitted.

In this way, the cassette JO installed in the main body B of a copying machine etc.
On the surface of the lid 1, there are many protrusions 1b, 1-b, IL)... in the direction of movement of the manual feed No. l
A is formed. Sea 1-P is that side 111Ai
After pressing the edge against the rising kite 1a, the operator securely presses the sheet +-13 onto the paper feed roller or other paper feed means in the main body B along the direction of the protrusion 11 in the same direction n:j. We must move forward until we have it.

Therefore, the operator must push the sear +-1) toward the side edge and always maintain that direction while moving it forward. If he is not careful, he may overdo it and cause a jam, or the inside of the main body may jam. Even if the sheet passed through it, there was no risk of damage or damage to the sheet itself.

The present invention has been made in view of the current situation, and FIG. 2 shows an embodiment of the present invention, which is a cassette used in the same manner as the one shown in FIG.
Corresponding parts are indicated by the same reference numerals. What about this thing? A large number of protrusions are provided on the lid 1, which has a flat surface.
..., when viewed in the direction of travel of the manual sheet, all of them stand up and extend in a direction approaching the kite 1a.

Therefore, if the sheet P is placed on this surface and the user moves it forward while holding it, the sheet becomes a protrusion] b
Kite 121 stands up guided by , J, b...
As the position of the seat is shifted in the direction of The sheet can be easily fed into the main body B while maintaining a predetermined position and direction without being attentive.

The figures shown in Figure 3 and below all show other embodiments in which the present invention is applied to the lid of a cassette, similar to Figure 2; b... is tilted in the direction of the rising guide in the same way as shown in the second figure, and the lid surface itself is tilted so that the side on which the rising kite 1a exists is the lowest, and placed on this. The structure is such that the sheet is biased in the direction of the rising guide by its own weight.

The one shown in FIG. 74 has a slope similar to that shown in FIG. The one shown in Fig. 5 is the step part l shown in Fig. 4.
c, lc, . . . are constructed so that they gradually deflect in the direction of the rising guide ]a when viewed in the traveling direction of the sea I.

In the embodiment shown in FIG. 6, a plurality of (two in the illustrated example) protrusions 1d, Ic, etc. are provided on the surface of the lid 1. In this case, it is convenient to keep the height of the risers close to I and Ja low. Like this+
By forming 11゛f, as shown in the same figure, by placing sheets h, P+, P2, etc. of individual sizes on one of the corresponding protrusions, one edge of the sheet can be raised up to h. It can be automatically brought into contact with the object and fed in the correct direction.

m The one shown in Fig. 7 has an inclined surface 1" that is lowered in the vertical direction on a part of the surface of the lid at a suitable place.
In this case, one bit is secured in the direction of sea i.

As explained above, in the present invention, when feeding the manual sheet 1- to the image forming apparatus, the sorting process 161. In order to determine the direction, the operator of the manual feed sheet h can write a note on the guide part M (vertical Nilinonoid, etc.) provided for N-1 and guide +Xp, and it is configured so that it is automatically brought to without special attention,
This seal can be fed into the device very easily and accurately.

Note that although an embodiment in which the present invention is applied to a cassette lid has been described, the present invention is not limited to this and can be applied to other manual feed mechanisms, and the present invention can be applied not only to image forming apparatuses, but also to other manual feeding mechanisms. It is easy to understand that the present invention can be applied to document feeders, printing machines, and other types of paper feeding mechanisms for sheet materials.
