Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a document insertion device such as a copying machine.

[Conventional technology]

2. Description of the Related Art Conventionally, as an example of a document insertion device such as a copying machine in which a document is inserted manually, there has been known a device having a configuration as shown in FIG.

In FIG. 5, 10 is the main body of the copying machine, 11 is the document insertion slot, 12 is the feed roller, 13 is the document insertion device, 14 is the shelf body, and 15 is a movable body, and the document a is placed on the movable body 15. Place the movable body 1
5 and the original a are moved in the original insertion direction by an operator, and are transferred from the original insertion opening 11 to the feed roller 12. Note that FIGS. 6 and 7 are a plan view and a sectional front view of essential parts of the document insertion device 13 shown in FIG. 5.

[Problem that the invention attempts to solve]

However, in the above conventional structure, as shown in FIG. 6, the tip of the movable body 15 is formed in a straight line, and as shown in FIG. 7, the movable body 15 itself has a certain thickness. Therefore, even if you place the original a with the leading edge of the original a aligned with the leading edge of the movable body 15 and try to push the movable body 15 to bring the leading edge closer to the grips of the feed rollers 12, 12, The tip of the movable body 15 is the feed roller 12,
12, making it impossible to reduce the distance between the grip and the leading edge of the document to less than a certain distance. Therefore, in order to hold the original document a in the grip portions of the feed rollers 12, 12, it is necessary to place the original document a so that the leading end thereof protrudes from the leading end of the movable body 15. However, since the original position of the original a is regulated by manual feeding with the leading edge of the document a aligned with the leading edge of the movable body 15, the position of the leading edge of the movable body 15 and the original are If the position of the leading edge of document a shifts, a problem arises in that document a cannot be maintained in the correct orientation.

The present invention solves the above-mentioned problems by ensuring that the document placed on the document shelf is firmly held by the feed rollers of the conveying device in a document insertion device having a sliding document shelf, thereby allowing the document to be inserted smoothly. The purpose is to solve the problem.

[Means and actions for solving problems]

The present invention uses a copying machine, etc., which has a document shelf that is slidable in the document insertion direction outside the document insertion slot, and a feed roller or feed belt that transports the document placed on the document shelf to the platen section. In the document transport device, a notch is provided at the tip of the document shelf to accommodate a grip portion of a feed roller or a feed belt, so that the document placed on the document shelf is securely held between the upper and lower feed rollers at the notch. , which allows for easy insertion of originals.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

1 is a plan view of the main parts of the document insertion device according to the present invention, FIG. 2 is a sectional front view taken along the line - in FIG. 1, FIG. 3 is a plan view of the document insertion device according to the present invention, and FIG. The figure is a sectional front view taken along the - line in FIG. 3.

In FIGS. 1 to 4, A is a main body of a copying machine, and a document insertion device 1 is disposed in the upper part of the main body A. In FIG. Then, the document insertion device 1 transports the document a from the document insertion opening 2 to a platen portion (not shown).

The document insertion device 1 described above is configured as follows. That is, a rectangular horizontal plate-shaped document shelf 3 on which a document a is placed and slides in the direction of the document insertion port 2 is provided in front of the document insertion port 2. Rotary wheels 4, 4, . wheel 4,
4... is supported by the manuscript shelf support 5,
The folding plate portion 3a of the document shelf 3 is locked to the rotating wheels 4, 4, .

Furthermore, as shown in FIG.
Notches 7, 7, etc. are provided in the corresponding portions, and when the document shelf 3 is pushed in the document insertion direction, the grip portions G of the upper and lower feed rollers 6, 6
enters the notches 7, 7 . Therefore, the document a aligned with the leading end 3b of the document shelf 3 is securely held between the upper and lower feed rollers 6, 6, as shown in FIG. 2, and is transferred to a platen section (not shown). Note that at this time, the original sheet 3 does not come into contact with the feed rollers 6, 6, etc. at all.

The present invention is constructed as described above, and when the leading edge of the original a is aligned with the leading edge 3b of the original shelving 3 and the original a is aligned in the correct posture, and the original a and the original shelving 3 are pushed, the feed roller 6 ，
The grip portion G of No. 6 enters the cutout portions 7, 7, . . . and grips and conveys only the document a.

In the embodiment of the present invention, the document a is conveyed by the feed rollers 6, 6, but a feed belt (not shown) may be used instead, and in this case, the document sheet 3
A notch for accommodating the grip of the feed belt may be provided at the tip of the feed belt.

[Effect of idea]

As described above, the present invention has the following effects.

(i) Since the leading edge of the original can be placed with the leading edge of the original shelf, the orientation of the original can be set correctly.

(ii) The document is securely held by the feed roller in the notch of the document shelf, and the document can be inserted properly.

(iii) There is no possibility of the document sheet coming into contact with the feed roller.
