Abstract

PURPOSE:To set an original without drooping it by providing a magnet which is adsorbed so as to be freely attachable and detachable to the front end part of an original guide table, on both ends of a cylindrical original containing body having a slit-shaped original feeding port extending in the axial direction. CONSTITUTION:A titled device is provided with a cylindrical original containing body 12 having a slit-shaped original feeding port 11 extending in the axial direction, side plates 13, 14 are fitted to both ends of its containing body 12, and arm parts 15, 16 are formed as one body on the side plates 13, 14. Nearly L- shaped magnets 17, 18 are fixed to the lower face of the arm parts 15, 16, and the magnets 17, 18 are adsorbed so as to be freely attachable and detachable to the front end part of an original guide table 19 made of a sheet metal. Also, a mark 21 for designating a placing position of an original 20 is put on the upper face of the original guide table 19.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a document feeding device used in a moving document copying machine.
Regarding. 2 [Prior Art] A copying machine that copies long or large originals automatically transports the original placed on an original guide table to make copies. Long manuscripts include Char 1, etc. of various 3I instrument recorders. l2 dog J+1 yen! The manuscript includes drawings in F3 size and above.

FIG. 1 shows an example of such a conventional copying machine.

When copying with this duplex machine, first place the original 3 on the original guide table 2 provided on the front of the main body 1 of the copying machine, and insert the leading edge of the original into the original insertion slot 4 provided on the main body 1 of the copying machine.
Insert as appropriate. When the start button on the operation panel 5 is pressed in this state, the feed roller provided in the copying machine main body 1 begins to rotate, the conveyance of the original 3 is started, and copying is performed in a well-known manner. When copying is completed, the original 3 and copy paper (not shown) are discharged to the rear or above of the copying machine main body 1.

By the way, in order to reduce the size of such copying machines,
The length of the document guide table 2 in the front-rear direction is made relatively small. For this reason, do you use a long manuscript or a fake manuscript 3 as a manuscript guide? If you place it on the
, - [Shimau. If the document 3 sags, it is likely to be soiled or damaged, and scratches or scratches may occur, so the operator's assistance is required.

Therefore, some conventional copying machines have a document guide table 2 of a pull-out type so that its substantial length can be increased.

However, even if the document guide table 2 is of a pull-out type, its actual length cannot be made sufficiently long, so that the document 3 still protrudes and hangs down. Furthermore, since the document guide table 2 is pulled out in front of the copying machine main body 1, it becomes a hindrance to the operation.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a document feeding device that can set documents without hanging them down.

[Invention +I? ]

In the present invention, a cylindrical document storage body having a slit-shaped document supply 1 is provided, and a document is stored in a roll in the +xis of the container, and the tip thereof is protruded from the document supply port. The magnets provided on both sides of the document storage body are detachably attracted to the ridi portion (in front of the document guide table).

〔Example〕

The present invention will be described in detail with reference to Examples below.

FIGS. 2 to 4 show a document feeding device according to an embodiment of the present invention.

This device includes a cylindrical document storage body 12 having a slit-shaped document supply port 11 extending in the axial direction. Side plates 13 and 14 are fitted to both ends of the document storage body 12. The arm portion 15 is attached to the guide plate 13.14.
．． 16 are integrally formed. A substantially L-shaped magnet 17.18 is fixed to the lower surface of the arm 15.16.

The magnets 17 and 18 are detachably attracted to the front end of a plate-shaped document guide table 19 provided on the front surface of the main body of the copying machine (not shown). When the magnets 17 and 18 are attracted to the A41 document guide table 19, the document supply port 11 is located in front of the document guide table ■9. iNi
It is located near the area. On the lower surface of the document guide table 19, a document 20, (Dil'I2
"j3. (57m 'c += :1iT14'°"
0'-1"11.

When using this device to place a long or large original 20 on the original guide table 19, the original 20 is first rolled into a roll and stored in the original storage unit 12, and the leading end of the original is placed in the original supply port 11. Protrude as appropriate. After this, the stones 17 and 18 are attracted to the front end of the document guide table 19. At this time, both sides of the document 2σ- protruding from the document supply port 11 are made to match the marks 21 corresponding to its size. Thereafter, the original 20 is pulled out by holding the leading edge thereof, and is appropriately inserted into an original insertion slot (not shown) provided in the main body of the copying machine. In this state, the leading end of the document 20 is placed on the document guide table 19, and the remainder is stored in the document storage body 2 in the form of a roll.

Thereafter, when the start (not shown) is pressed, the document 20 is smoothly conveyed by the rotation of the feed roller (also not shown).

〔Effect of the invention〕

As described above, according to the present invention, the original can be set without hanging down, so it is possible to effectively prevent the original from being soiled or damaged. Further, since the original is stored in the original in the form of a roll, it can be transported without causing skew, and operator assistance is not required, improving operability.

Also, since the space occupied by the document storage unit is relatively small,
It does not interfere with operation. Furthermore, since the document storage body is attached to the document guide table with a magnet, it is extremely easy to attach and detach it. Furthermore, the document storage body can also be used for storing documents. In addition, if the original is stored in a roll, it can be set without straightening the curl.
