Abstract

PURPOSE:To automate postprocessing in case of a paper jam, and eliminate troublesome postprocessing operation for the paper jam by providing the 1st group which inverts and sends an original into a stand-by means when only one surface is copied, and the 2nd roller group which sends a both-surface original directly into the stand-by means. CONSTITUTION:An original 5 which is copied at a copying position on a platen 3 is sent to the 1st roller group 14 by a conveyor belt 11, and further inverted and carried in the stand-by means 17 through the 2nd roller group 16. When a copy form is discharged without any jam, the original 5 is carried in an original storage part 4 from the stand-by means 17, but if a paper jam occurs, a following original 5 which is already carried onto the platen 3 is discharged onto the original tray 12 and the original 5 held in the stand-by means 17 is sent onto the conveyor belt 11 by the 5th roller group 21 and further sent to the copying position on the platen 3 by the conveyor belt 11 to take a copy.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a visual document feeder for conveying a document onto a platen of a copying machine.

PRIOR ART In conventional manual document feeders used in copying machines, etc., when a paper jam occurs after copying, a worker first removes the subsequent abrasive paper set on the platen, and then removes the preceding document that has already been ejected. Either set the fc original on the platen again and make a copy, or recirculate the set original (-IJ), which may cause a paper jam, and then set the fc original on the platen and make a copy again, which is a very complicated operation. Met.

Purpose of the Invention The present invention was made for the purpose of improving the above-mentioned problems, and it provides an MIh document feeder u that automatically performs post-processing when a paper jam occurs. This eliminates the need for complicated post-processing operations.

A document stored in a KL bucket storage section is carried to a copying position above the platen of the 44-form copying machine of the invention.

A carry-out belt is provided to carry out the copy from above the platen after copying, and on the document carry-out side, a copy of the document carried out by the conveyor belt is ejected from the copying machine. A standby means is provided to wait for 4 years, so that if a paper jam occurs, the paper that has already been loaded onto the platen will be ready for use. At the same time, the previous original is returned to the platen from the upper standby means to remove the paper jam from the original AI4, and the double-sided original In the case of 1-sided f&iM entertainment bale means, the original is
An excitation source 41 and a roaring feed device are arranged so as to pass through the 0-ra group and the upper side of the conveyor belt and onto the platen.

An embodiment of the present invention will be described in detail with reference to FIG. 1i1. 1 is placed on the platen 3 of the copying machine 2. In the main body of the apparatus a, there is a door 4 with an open top in the center of the upper part. 145 is stacked on this cool + TJ storage part 4 and fc

Reference numeral 6 denotes a vacuum feeder provided at the lower part of the document transport lower side of the document storage section 4, which includes an endless feed belt 8 rotated by a drive system (not shown) in the direction of the rainbow arrow, and a vacuum feeder 6 that sucks the document 5 and feeds the document 5. A suction means 9 such as a blower pressed onto the belt g and a strong force;
The raw materials 845i stored in the raw material Mj storage section 4 are sucked up one by one from below and sent out by the feed belt 8 through the conveyance path 10 to the lower conveyance between the platen 3 and the conveyor belt +1 installed above this. It looks like it's going to be stolen. An original 4 insertion tray 12 is provided in the middle of the conveyance path IQ, and the original 4 insertion tray 12 allows the original 5 to be copied by manual insertion. It is ready for import. The conveyor belt 11 is baked between rollers 13 provided on both sides of the platen 30 ψ1! The lower side ■α is in contact with the upper part of the platen 3, so that the document 5 carried between the platen 3 and the transport belt H is conveyed to the copying position on the platen 3. It has become. 1st place fk in doubles
The original document 5 is made into a temporary copy 2 and copied, and the copied original 5 is transferred onto the conveyor belt H to the 10th group 14. The 10th line IP I4 is located at the original transport position 0Ill, and when the placed end of the transported IGI 4M 5 crosses the branch path 15, it is reversed to the turn 113 and the original 5 is transferred to the branch Y615↓. 20
When the -ra vertical position 16 is inverted by 4 degrees into the standby means 17 installed above the 10th -r group 14 (1 l is inserted), the standby means +7 is the above-mentioned 'J: The 30th-7th group 18 is almost as simple as the upper side 116 of the i-feeding belt 11.

When the copy paper/JX Copy 2 is ejected without a paper jam, the ejection No. 16 is used for waiting means 17 The 3rd g-ra IJ418 sends out the raw material 4i45 to the conveyance path 19. A 40th-light 1 2o is provided in the downward feeding path 19, and the 1st, 20th-ra 4f4''l 4',
It is reversed by I b and moves to the top of the original t1.115 stored in the grinding storage part 4 of the main body 1. - When a paper jam occurs in the copying machine 2 when a copy of the original 5 waiting in the standby means 17 after 10,000 copies has been completed, the conveyor belt 1 is reversed by the paper jam signal and the original 5 has already been carried onto the platen 3. The subsequent document 5 that has been inserted is ejected onto the document insertion tray 12. Thereafter, as the conveyor belt 11 rotates forward, the document 5 waiting in the waiting means 17 is transferred to the 50th-ra'tF.
+21, the document is conveyed to the upper side 11b of the conveyor belt I+, and further conveyed by the conveyor belt 11 to the copying position on the transverse platen 3, where the preceding document 5 is copied again. The original 5 that has been copied is placed in the first page. 20th - La Z (Hand 14.16)
It is then carried into the waiting means I7. If no paper jam occurs again, the document is carried into the document storage section 4 via the 41st I-ra group 20'e.

Thereafter, the user's operation is repeated to copy all the originals 5 stored in the original storage unit 4.

The above is a case of copying a single-sided original 5, but in the case of a double-sided original 5, first, the single-sided original (original) rr = 5 passes through the 20th-A group 16, and then is transferred to the standby means as shown by the chain line. +7
Transported to. After that, the 20th group 18 and the 50th group 2I feed the conveyor belt Il to the upper side 11A, and then the conveyor belt 11 carries it to the copying position on the sieve laten 3, where it is transferred to the surface that has already been copied. The other side of is copied. After the legal copying of both sides has been completed, the 7'ic original copy 5 is the same as the one-sided original 5. Second. 30th-A group 14°+6. +
8 and is carried into the document storage section 4 by the 40th group 20.

If a paper jam occurs while conveying the fit document 5 by the conveyor belt 11 to copy both sides, the document 5
The opposite side is not photographed and is conveyed from the top of the platen 3' to the standby means 17 via a plumb line path, and then transferred to the 50th-ra group 21.
The paper is then transported via the transport belt 11 to the copying position on the platen 3, and the copy on the side where the paper jam occurred is again copied.

Note that the subsequent operations are the same as those in the case where no paper jam occurs, so the explanation will be omitted.

Effects of the Invention As described in detail above, the present invention provides the following advantages:
Waiting means I until the paper is ejected from the copying machine 2
7, and if a paper jam occurs, use the standby means +
The document 5 that is waiting at 7 is fed back onto the platen 3 for copying, and all the post-processing is done manually, so it is no longer necessary to copy the document 5 that has already been set. There is no need for troublesome steps such as re-centing the original 5 that has been removed and a paper jam occurs, and productivity is greatly improved. Furthermore, even if a paper jam occurs during double-sided original copying, subsequent processing is carried out manually, making it much easier to align the pages after a single paper jam occurs than in the past.
