Abstract

PURPOSE:To make a manually fed paper sheet feeding guidable easily and smoothly into a paper sheet feeding part, by setting one side of a paper sheet guiding member down to a feeding device of paper sheet from the outside and the other side to an enclosure part covering the paper sheet feeding part from outside. CONSTITUTION:A plate spring 10 and a paper feeding roller 11 attached to a manual feeding table 9 are lightly brought in contact with each other in a state of manual operation. Likewise, a paper feeding part enclosure 12 is supported on a paper feeding part stay 13 by a retainer plate spring 15. And, one end part of the paper feeding closure 12 causes clearance between it and the manual feeding table 9 being in a state of annual operation to be gradually narrowed, while being bent as a guide part 121 to advance the paper sheet up to a contact part between the roller 11 and the plate spring 10. According to this method, even when the paper sheet inset by manual operation and the like is curled or of a sizable one in thickness, this guide apparatus can guide the paper sheet into the feeding part smoothly and accurately without suffering any damage so that not only unevenness at the rear end side of the paper sheet can be checked but smooth paper feeding can be achieved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a manual receipt guide device for copying machines, printing machines, and other machines having a mechanism for conveying sheets (hereinafter referred to as "copying machines, etc.").

Conventionally, in this type of manual sheet guide device, for example, as shown in FIG. 1, when manually feeding paper, when the manual feed tray 1 is pulled down to the dot position (position at, indicated by the two-dot chain line in FIG. 1), the manual feed tray l
The transfer paper 3 in the cassette 2 is pushed down, and the manual feed stand l enters between the paper feed roller 4 and the transfer paper 3,
It makes light contact with the leaf spring 5 attached to the paper feed roller 4. Then, the leading edge of the transfer paper 3 is placed along the manual feed table l into the paper feed roller 4.
The transfer paper was set by sliding it until it stopped when it was caught between the and plate spring 5, and by pressing the print button, the paper feed roller 4 was rotated to manually feed the paper. In such a case, 11 the transfer paper will hit the paper feed section cover 6 supported by the main body 7 and cannot be set properly, and when feeding thick transfer paper, the paper feed section cover 6 may be This has the disadvantage that it rubs against the transfer paper and damages the transfer paper, or causes jams.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a new manual sheet guide device that is improved in view of these drawbacks.

Another object of the present invention is to provide a manual sheet guide device that can easily and smoothly guide manual sheets to a sheet feeding section.

That is, the main structure of the present invention that can achieve the objective 1-1 is a manual sheet guiding device that has a guide member that guides sheets one by one from outside the machine to a conveyance path outside the machine, and the single force of the guide member is This is a manual receipt guide device characterized in that a kite part guides sheets from outside the machine to a feeding means, and the other part is a part of a cover that covers the sheet feeding part from the outside.

Hereinafter, a specific embodiment of the present invention will be described in detail with reference to FIG. FIG. 2 is a small sectional view of an embodiment of the invention. In the figure, 9 is a manual feed stand, 1O is a leaf spring, 11
12 is a paper feed roller, 12 is a paper feed section cover, 13 is a paper feed section stay, 14 is a machine main body stay, and 15 is a presser plate spring.

The leaf spring lO attached to the manual feed stand 9 with screws or the like and the paper feed roller 11 are in slight contact with each other in the manual feed state as shown in FIG. The paper feed section cover 12 is connected to the paper feed section stay 13.
The machine main body stay 14 is supported by a screw (not shown).

As shown in the figure, the gap between one end of the paper feed unit cover 12 and the manual feed table 9 in the manual feed position gradually narrows, and the transfer paper is placed in contact with the paper feed roller 11 and the leaf spring 10. It is bent to form a kite section 12 □ that allows the kite to be advanced to the desired location. Also, this guide part 12□
Next, another embodiment will be described with reference to FIG. 3, in which the paper feed roller 11 rotates and acts to press down the rear end side of the transfer paper during manual paper feeding.

Components that function in the same way as the embodiment shown in FIG. 2 are given the same numbers and their explanations are omitted.
A thin shaft 123 is fixed to the tip of the shaft 12, and a roller 122 is rotatably supported on the shaft 12. axis 1
The inner diameter of the roller 122 is slightly larger (preferably 1 to 1.5 am) than the diameter of the paper feed section cover 12, so that the transfer paper that is in contact with the manual feed table 9 due to its own weight will be placed under the paper feed section cover 12. The tip is guided along the guide portion 12 □, enters between the roller 122 and the manual feed stand 9, and is smoothly advanced to the point where the paper feed roller 11 and the leaf spring 10 are in contact. Thereafter, paper feeding is performed in the same manner as in the previous embodiment. Further, in this embodiment (FIG. 3), the transfer paper does not directly touch the paper feed section cover 12, so the transfer paper is not damaged. Furthermore, if the rollers 122 are too light, they will not be able to sufficiently press down the transfer paper, so it is desirable to use a material such as metal with a high specific gravity. In place of this roller 122, a soft and thin needle is attached to the tip of the paper feed section cover 12 so as not to obstruct the progress of the transfer paper, and is perpendicular to the direction of force or the direction of movement of the transfer paper, or at a certain angle. A similar effect can be expected even if a large number of them are attached facing the same direction.

As explained above, according to the configuration of the present invention, even if the sheet inserted by hand or the like is curled or thick, it can be easily guided without damage. Furthermore, it is possible to suppress fluttering on the rear end side of the sheet, thereby enabling smooth feeding.
