Description

[Detailed description of the invention] <Technical field> This invention relates to a paper feeding device in a copying machine.
More specifically, the present invention relates to a paper feeder into which copy paper can be fed manually.

<Prior art> Copying machines have conventionally used devices for temporarily storing and placing originals for copying, such as devices with a mounting table protruding from the side of the copying machine, or devices that store originals on an openable document holder. In the former case, in a copying machine in which the document table moves back and forth, it is either impossible to form such a pocket, or even if it is formed, it is not placed in a suitable position because it interferes with each other. The problem was that it could not be set up. Further, in the latter case, it is necessary to open and close the document presser, making it troublesome to take in and take out the document, making it inconvenient to use.

On the other hand, in recent years, in addition to a cassette-type automatic paper feeder, copying machines equipped with a manual paper feeder have been provided, and in such a copying machine, the paper feed Some models have a document storage section in the stand (for example, see Japanese Utility Model Application Publication No. 142045/1983), but in all of them, the input section for manual copy paper is open, so the document can be stored in the copying machine itself. Otherwise, scraps, pencils, etc. may easily fall into the copying machine body from the above-mentioned input section, which may cause trouble. A type of copying machine in which the document storage section runs along the side of the copying machine body covers the cooling air suction port formed in the side, resulting in a problem of poor air suction.

<Objective> The object of this invention is to provide a paper feeding device for a copying machine that can solve the above-mentioned conventional disadvantages, has a simple structure, and can easily place a document.

<Structure> The structure of the paper feeder of this invention to achieve the above purpose is that it has a manual paper feed tray that can be turned toward the main body of the copying machine and then folded back to the top of the paper feed tray. The present invention is characterized in that an auxiliary part is extended to cover at least the upper part of the copy paper input part and can be used as a temporary document mounting table.

<Examples> Examples will be described in detail below with reference to the accompanying drawings showing examples.

FIG. 1 is a perspective view of a copying machine equipped with a paper feeder 1 of this invention, showing a copying machine in which a document table a moves back and forth. The paper feed tray 10 of the paper feed device 1 is installed in an inclined manner to protrude from the input section c for manually fed copy paper above the paper feed cassette b, and the paper feed tray 10 has its inclined lower end located inside the copying machine. It is held by fitting into the insertion part e.

Reference numeral 20 denotes an auxiliary part extending from the sloping upper end of the manual paper feed tray 10, which is rotatably fixed to the paper feed tray 10, and when turned toward the main body of the copying machine. A temporary document mounting table can be constructed by covering the copy paper input section c. That is, as the auxiliary part 20, an extension part 22 is formed on a rectangular main body part 21 provided flush with the upper surface of the paper feed tray 10 to be stored under the paper feed tray 10 in a paper feeding state. At the same time, inclined side plates 23 are erected on both sides of the main body part 21, and an extensible plate 24 that can be freely moved in and out of the extension part 22 is constructed, and a long hole formed in the side plate 23 is provided. A stop shaft 11 formed upright at the end of the paper feed tray 10 at the 23' portion.
(See Fig. 3) is provided so that it can be rotated toward the copying machine main body side by inserting the main body 21 and the side plates 23 on both sides of the main body 21 and the side plates 23 on both sides of the main body 21. It covers both sides and allows documents to be placed on the top surface of the rotation. The above-mentioned extensible plate 24 is used by moving it in and out as appropriate depending on the size of the original, and can also place a copied original. This telescopic plate 24
is attached to the extension part 22 so as to be freely removable and removable by a bolt passing through the long groove 24'. 25
is a cushion member made of rubber urethane or the like provided on the extensible plate 24, and acts as a buffer against the paper feed table 10 when the auxiliary part 20 is returned from the rotated state to its original state. In addition, the auxiliary part 20
In the rotating state, the end of the main body part 21 is brought into contact with the main body of the copying machine to prevent rotation,
In the rotated state, the main body 21 is positioned below the air suction port d of the copying machine main body so as not to block it. Therefore, the flow of air within the main body of the copying machine is not obstructed. In addition, when turning the auxiliary part 20, in order to prevent the top of the side plate 23 from protruding into the main body of the copying machine, during the rotation, pull the copying part 20 along the elongated hole 23' and move it away from the main body. and finally return it to the main body. Since the upper side and both sides of the copy paper input section c are covered when the auxiliary section 20 is rotated, it is possible to completely prevent the inconvenience of clips, pins, and pencils falling from the input section c into the main body of the copying machine. become.

On the other hand, a pair of guide members 12 are formed on the paper feed tray 10 to guide both sides of the copy paper to be input. The mechanism allows the guide to slide evenly from side to side, making it easy to adjust the guide width.

Note that the auxiliary part 20 includes at least the main part 2.
In addition to cases where the side plate 23 is provided only on the front side, there are also cases where the side plate 23 is not formed at all, and when it is not formed at all, the copy paper input section c is placed on the top side. only will be covered.

Further, in the embodiments described above, the auxiliary part 20 may be configured so that in the rotated state, the auxiliary part 20 is horizontal or the side of the main body of the copying machine is lowered.

Furthermore, the above-described paper feeding device 1 is applicable to not only a copying machine of the type in which the illustrated manuscript table moves back and forth, but also
Of course, it can also be installed in a type of copying machine where the original table is fixed and the optical system moves back and forth.

<Effects> According to the paper feeding device for the copying machine of this invention configured as described above, the manual paper feeding tray is provided with an auxiliary part that can be turned upward toward the copying machine main body and then folded back and turned upwards. The auxiliary part can be rotated toward the main body of the copying machine to cover at least the upper part of the copy paper input section and used as a temporary document placement table. In addition to this, the original can be easily placed without being drawn into the copying machine main body.

In particular, since the auxiliary section covers at least the upper side of the copy paper input section in the rotating state, there is no fear that clips, pencils, etc. may fall into the copying machine body from above, and troubles caused by falling clips, etc., can be prevented. This can be prevented.

Further, the overall structure is simple and the price is low, which provides unique practical effects.
