Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet loading table used as a document loading table, a paper ejecting tray, or a copy sheet receiving tray of a paper feeding device in a facsimile machine, a copying machine, etc., and particularly relates to a foldable sheet loading table. .

Various types of foldable seat mounting tables have been proposed in the past. The purpose of folding these sheet rests is often to keep the sheet rest out of the way when not in use, and for this reason, conventional sheet rests cannot be used as sheet rests when folded. Many things are useless.

SUMMARY OF THE INVENTION An object of the present invention is to provide an improved foldable sheet mounting table that can be used as a sheet mounting table even in a folded state and can be used depending on the size of the sheet to be placed.

According to the present invention, this purpose is achieved by:
a roller shaft that is provided near an end of the main mounting table and carries a guide roller; a folding position that is pivotally supported near the end of the roller shaft and superimposed on the main mounting table; and the end of the main mounting table. This is achieved by a sheet mounting table having an auxiliary mounting table which is rotatable between a section and an extended position extending substantially in the direction of extension thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings.

FIGS. 1 and 2 show one embodiment in which the sheet placing table according to the present invention is applied as a transmission document placing table of a facsimile paper feeder, of which FIG. 1 shows an auxiliary placing table that is foldable. FIG. 2 shows the state when the auxiliary mounting table is in the extended position. Further, FIG. 3 is a perspective view of the auxiliary mounting table seen from above when it is in the folded position, and FIG. 4 is a perspective view of the same seen from below. In these figures, reference numeral 1 indicates a main mounting table which is provided with a relatively gentle slope. In the figure of the main mounting table 1, there is a shaft 2 at the left end.
A rotatable separation roller 3 carried on a shaft 4 and a non-rotatable brake roller 5 carried on a shaft 4 are arranged opposite to each other so as to be in contact with each other. Further, openings 6 and 7 are provided in the middle portion of the document mounting table 1. As shown in FIG. A rotatable feed roller 9 carried on a shaft 8 is located in the opening 6 . Further, a rotatable guide roller 11 supported by a shaft 10 is provided near the right end of the main mounting table 1 in the drawing. The shafts 2 and 8 are each rotatably supported by a side plate of the device not shown in the figure, and are each rotated counterclockwise in the figure by an electric motor not shown in the figure. It is designed to be rotationally driven. Further, a stopper plate 12 is provided near the left end of the main mounting table 1 in the figure, and this stopper plate 12 holds several sheets of transmission documents between the lower end of the stopper plate 12 and the main mounting table 1. A relatively small gate gap 13 is defined that allows only the passage of.

Reference numeral 14 indicates an auxiliary mounting table, and this auxiliary mounting table 14 has brackets 15 on both side edges near the end thereof, and the shaft 10 is connected to the shaft 10 via a bearing sleeve 16 at this bracket 15. supported,
As shown in FIG.
As shown in the figure, the main mounting table 1 is rotatable between an extended position extending substantially in the extending direction from the right end in the figure. When the auxiliary mounting table 14 is in the extended position, the stopper piece 17 formed at the end thereof closes the main mounting table 11.
It comes into contact with a rubber plate 18 attached to the lower bottom surface of the holder, thereby determining the extending position. Further, the auxiliary mounting table 14 has a grip portion 19 at the other end. Further, the auxiliary mounting table 14 has an opening 20 near the one end thereof into which a part of the guide roller 11 can rotatably enter. The auxiliary mounting table 14 has an opening 21 in the middle thereof, and a guide roller that can freely rotate via a shaft 23 pivotally supported by a bracket 22 integral with the auxiliary mounting table 14 is installed in this opening 21. 24
is provided. This guide roller 24
As clearly shown in the drawings and FIG. 4, it protrudes from both the front and back surfaces of the auxiliary mounting table 14, and when the auxiliary mounting table 14 is in the folded position as shown in FIG. 1 said opening 7
It is becoming more and more engaged.

As shown in FIG. 1, the auxiliary mounting table 1
4 is in the folded position, the auxiliary mounting table 14 is in a state where it is tightly overlapped with the upper surface of the main mounting table 1 as shown in the figure, so even in this state, the main mounting table 1 and Auxiliary mounting table 1
The original to be transmitted can be placed on the image forming apparatus 4 in such a manner that it can be automatically fed. At this time, the guide roller 11 is
Together with the guide roller 24, the document to be transmitted is moved smoothly. When the auxiliary mounting table 14 is in the folded position, if you wish to send a relatively long document that cannot be placed on the auxiliary mounting table 14, hold the gripping portion 19 and move the auxiliary mounting table 14 around the axis 10 as shown in FIG. It is sufficient to rotate it clockwise as viewed from the top and bring it to the extended position as shown in FIG. With the auxiliary platform 14 in the extended position, the main platform 1
When a relatively long transmission document extending over the auxiliary mounting table 14 is placed on them, the transmission document comes into contact with the guide roller 11 by its own weight, so that the transmission document teeth,
The actions of the guide rollers 11 and 24 and the feeding roller 9 ensure smooth feeding.

Further, at this time, the guide roller 24 also functions effectively to smoothly send out the transmitted document.

Further, according to the present invention, since the auxiliary mounting table 14 is pivotally supported on the shaft 10 of the guide roller 11, there is an advantage that a compact design can be achieved and the structure is simple.

Although the present invention has been described in detail with respect to specific embodiments above, it is understood that the present invention is not limited thereto and that various embodiments are possible within the scope of the present invention. This will be obvious to businesses.
