Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying machine, and particularly to a copying machine with a long original copying function that can easily copy any part of a long original.

[Conventional technology]

There are times when it is necessary to copy long originals, such as computer embossing paper, special blueprints such as city planning maps, etc., but until now, there have been no copiers that can copy all of the long originals. They used regular large copy machines and reduced copies of them.

In addition, as a copying machine that facilitates the copying of long originals, an exposure lamp is lit near the center of the platen glass, and the long original is run in that area to prevent scanning by running the original. A copying machine equipped with a document feeder for copying documents has been proposed.

[Problem that the invention seeks to solve]

When copying a long original using a conventional copying machine, the operator extracts the necessary part of the original for each copyable area of the copying machine used, and places this part on the platen glass surface. However, since the originals are long, they are difficult to handle, and the originals may be damaged or smeared while being handled.

In addition, in the case of a copying machine with a document feeder, the inconvenience in handling documents is considerably improved, but only the first part of the document is copied according to the copyable area determined by the copying machine. If the original is very long, such as roll paper, it is not possible to copy the part after the middle part. Therefore, in this case as well, when copying the part after the middle part, the operator must set the required part of the original on the platen glass in advance, which causes inconvenience in handling the original, etc. This has the same problems as when using a copying machine.

The present invention was made in order to improve the above-mentioned problems, and it is an object of the present invention to provide a copying machine with a long original copying function that can easily copy any part of a long original. purpose.

[Means and actions for solving problems]

In order to solve the above-mentioned problems, in this invention, the exposure lamp is stopped at a position below the platen glass so that it can be turned on, and a document feeder is provided to run a long document. In a copying machine that enables scanning,
a start button for starting the traveling of the original; a copy start button for turning on an exposure lamp and starting copying; and when the start button is pressed, the original feeder is always driven at a predetermined speed;
The apparatus is characterized by comprising a control means for starting copying when the copy start button is pressed at any time during the driving.

This eliminates the inconvenience of handling manuscripts,
It is extremely easy to copy any part of a long original.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a diagram showing a copying machine according to the present invention, and FIG. 2 is a diagram showing a control device.

In FIG. 1, a copying machine 10 has a platen glass 2 on the front, a control panel 3 having an operation section and a display section, and a long original document 1.
is placed. A long document 1 is stored in A, D, and H including a document feeder and a drive motor (not shown).
It is held movable in the direction of arrow A by an auto document handler (auto document handler) device. The document feeder may be composed of, for example, two rollers provided on the document supply side and the document receiving side, and
As seen in computer printers, a sprocket may be used to sequentially feed folded originals, and the receiving side may receive the folded originals. In addition, an appropriate feeding device such as paper feeding using friction of a rubber roller can be used.

Needless to say, the control panel 3 is provided with an L/D/C (long document copy) mode selection button for selecting the mode for copying long originals, a start button, and a copy start button. .

Such a copying machine is controlled by a control device shown in FIG. In FIG. 2, a central processing unit 21 receives outputs from various sensors 25, such as a sensor for detecting a long original, via an I/O controller 22. Also, via the I/O controller 22', the control panel 3
Displays messages related to copying machine operation on the display section and receives operation information from the operation section. 24 is a ROM that stores a control program, and 23 is a RAM that serves as a work area.

Next, the operation of the copying machine according to the present invention will be explained with reference to FIG.

First, turn on the copier and place the original in A.
Set it in the D/H device and start the machine. When the L/D/C mode selection button on the operation unit is pressed to select the L/D/C mode, the exposure lamp moves to near the center of the platen glass and stops there. Next, press the start button, A.
The drive motor of the D/H device is started, and feeding of a long original is started (step 1). Therefore, when the part of the document you want to copy passes the pointer provided on the appropriate part of the copying machine, press the copy start button, the exposure lamp will turn on, and the document will move Scanning is performed to obtain copies of the necessary parts (Step 2, Step 3). The installation position of the pointer is selected so that the time required for the document to move from that position to the position of the exposure lamp is equal to the time required for the copying operation to become possible after pressing the copy start button.

It goes without saying that a copy can be obtained by the process described above by pressing the copy start button each time the pointer position comes to the location that requires copying.

The copying machine detects whether the necessary copies have been output (step 4), continues operating only the A, D, and H portions (step 5), and detects that all originals have been ejected (step 4). 6) to finish copying.

〔Effect of the invention〕

As described above, in the present invention, by simply moving a long original and pressing the copy start button each time the pointer passes the pointer where the copy is required, copies of the required portions can be obtained very easily.
