Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a copying machine provided with an automatic document feeder for feeding a long document such as computer foam paper having continuous pages to a platen of the copying machine.

[Conventional technology]

2. Description of the Related Art A copier in which a long original having continuous pages such as computer foam paper is automatically conveyed to a copier so that each page of the original can be continuously copied is disclosed in, for example, JP-A-58-137854. And the like.

[Problems to be solved by the invention]

However, in the conventional copying machine, for example, an arbitrary page N, N + 1, N + 2 portion in the middle of the original as shown in FIG. 4 is copied, or as shown in FIG. And N + n cannot be copied.

[Means and actions for solving the problems]

The present invention has been made for the purpose of improving the above-mentioned conventional problems, and comprises an automatic document feeder for feeding a long document such as computer foam paper having continuous pages onto a platen of a copying machine one page at a time. Judging from the feed amount of the document by the feeder, a copy control device that issues a copy command each time a document of one page is fed onto the platen specifies an arbitrary copy start page of the document. Copy start page input means to perform, page count means to count the number of pages conveyed on the platen,
When the count value of the page counting means and the copy start page specified by the copy start page input means are input, the input copy is performed even though the original of one page is fed onto the platen. By providing the copy control device configured not to issue a copy instruction up to the page before the start page, a long document such as computer foam paper can be copied from any page. .

〔Example〕

One embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes a main body of the apparatus installed on a copying machine 2, which feeds a document 3 accumulated in a folded state toward a sheet carrying side. A feed roll 4, a registration gate 6 opened and closed by a solenoid 5, an endless transport belt 8 and a transport belt 8 for transporting the original 3 carried in by the feed roll 4 along an upper surface of a platen 7 of the copying machine 2. The roll 3 on which the original 3 is wound and the original 3 which is provided on the original discharge side and whose copy is completed by the copying machine 2
A document detector 12 for detecting the position and presence / absence of the document 3 is provided between the feed roller 4 and the transport belt 8.

A drive motor 13 is connected to one of the rolls 9 on which the transport belt 8 is wound. The drive motor 13 rotates the transport belt 8 in the direction of arrow A. A disk 14 having a large number of slits 14a in the peripheral portion and a pulse encoder 16 composed of a photo interrupter 15 are connected, and a pulse signal is sent to a control device 17 of the main body 1 with the rotation of the drive motor 13. I have.

As shown in FIG.
And the mode selection signals a, b, and c, the page designated for copying, the document size, etc., which are input from the keyboard 18, and the drive motor 13 and the registration The solenoid 5 of the gate 6 and the copying machine 2 are controlled.

Now, when the original 3 such as computer foam paper is set on the original loading side of the main body 1 and the continuous original copy mode is selected on the keyboard 18, the control flow proceeds from the step of FIG. 3 to determine whether all pages are copied. Is done. If all page copying has been selected in advance, the process proceeds to step S, where the transport belt 8 is intermittently driven by the drive motor 13 at a constant cycle, and the copying machine 2 starts from the first page of the document 3.
Are sequentially fed onto the platen 7 to perform copying (step), and at the same time, the presence or absence of the original 3 is determined based on the original detection signal sent from the original detector 12, and the last page of the original 3 is sent onto the platen 7 Steps (1) to (4) are repeated until the last page is copied, and the control flow is terminated.

On the other hand, when the partial copy is selected in the step, the process proceeds to any of the steps according to the modes a, b, and c.

The mode a is a mode for designating a copy start page and an end page. When this mode a is selected, the start page is entered in the step and the end page is entered in the keyboard 18 in the step. Subsequently, if there is no change in the input page in the step, the process proceeds to the step, in which the number of feed pulses up to the start page is calculated, the transport belt 8 is rotated by the drive motor 13 until the number of pulses is reached, and the document 3 is fed. .

Then, when the copy start page is set on the platen 7, the process proceeds to the step to start the copy, and the step → step → step is repeated until the last page is copied. When the last page is reached, the process proceeds to step to determine whether the next copy page is designated. If there is, the process returns to step and repeats the above flow. Send to

On the other hand, mode b is a mode in which copying is performed by designating a specific page. When this mode b is selected, a desired copy page is input in step and the process proceeds to step. If there is no change, the process proceeds to step and the original 3 is sent by the transport belt 8 to the copy page, and then copying is performed in the step.

After copying, the process proceeds to the step to determine whether the next page is designated. If not, the process proceeds to the step to discharge the remaining originals 3 to the paper output tray 10. If the next page is designated, the process proceeds to the step. After the original 3 is sent until the specified page is reached, the process returns to the step and copies the page. The above flow is repeated until the next page is no longer specified, and the process proceeds to the step when the next page is no longer specified.

Mode c is a mode for copying only the specified number of pages from the current page. When this mode c is selected, the number of pages to be copied is input in step, and the document 3 is conveyed at a constant cycle in step. A copy is made.

Then, it is determined in a step whether or not the designated number of pages has been copied. If the number of designated pages has not been copied, the process returns to the step and repeats the above flow. Is discharged to

In the above-described embodiment, the original 3 is fed by the conveyor belt 8. However, in the case where the feed holes are opened on both sides, such as computer foam paper, the original 3 is made use of the feed holes.
A tractor system may be employed, and a transport means such as a transport roll or a vacuum transport device may be used.

Further, the detection of the document feed amount is not limited to the pulse encoder 16, and the feed holes may be counted, or the rotation time of the drive motor 13 or the transport roll may be detected.

In addition, if a frequently used program is stored in advance in executing the program, it is not necessary to execute the program every time a part of a certain manuscript is called and copied. The document feeder of the present invention can transport not only continuous paper but also cut paper.

[Effect of the invention]

As described in detail above, the present invention provides an automatic document feeder for feeding a long document such as computer foam paper having continuous pages onto a platen of a copying machine one page at a time, and a feed amount of the document by the automatic document feeder. A copy start page input means for designating an arbitrary copy start page of the original, wherein the copy control device issues a copy instruction each time a one-page original is fed onto the platen. A page counting means for counting the number of pages conveyed onto the platen, and, when the count value of the page counting means and the copy start page specified by the copy start page input means are input, 1 is put on the platen. Before a copy command is issued, up to the page before the input copy start page is not issued even though the page has been fed. Because equipped with a copying control device, it can be a long document, such as a computer form paper copying from a desired page without performing the work in advance on the document itself. Further, even if a desired page is changed, it can be easily coped with simply by changing the input value.
