The present invention relates to a multi-integrated apparatus in which an original reservoir and a paper guide are integrated, and in particular, an integrated document storage reservoir and a paper guide for integrating the original reservoir and the paper guide in a multi-function apparatus using an inkjet printer to reduce and simplify the installation area. It relates to a composite device.

In general, facsimile is widely used as a recording device because of the high quality recording, easy maintenance, and low cost for recording a large amount of data. In addition, the ink quality of an inkjet printer that forms letters and prints on paper by heating the ink stored in the print head and generating bubbles like soap bubbles and spraying the bubbles through nozzles It is increasing significantly.

For this reason, recently, facsimile or multi-function devices adopting a printing method of a serial inkjet printer have emerged.

Using the accompanying drawings to explain, for example, US Pat. No. 5,359,423, the transfer process of recording paper or paper in a multifunction device employing the printing method of such an inkjet printer is as follows.

1 is a cross-sectional side view of a composite apparatus using a conventional inkjet printer. As shown, the devices mounted in the composite apparatus are supported by a main body 1. In order to transfer the paper supported by the main body 1 and recording the text or information, the paper on which the text or information is recorded is stored in the document holder 2a. The paper on which the information stored in the document holder 2a is recorded is guided through the document guide 2b and the document table 2c and conveyed by the document automatic separation transfer roller 2d.

At this time, the paper recording the information conveyed by the rotation of the document automatic separating and transporting roller 2d is to feed a large amount of paper stored in the document support 2a one by one due to the frictional force generated by the friction pad 2e. do. When the sheet on which information is recorded by the friction pad 2b is fed one by one, the sheet fed by the contact sensor 2f is sensed.

The sheet on which the information fed by the contact sensor 2f is recorded reads the information recorded by the white roller 2g. The information read by the white roller 2g is converted into transmission data in the main board 4. When the read operation is completed, the paper conveyed toward the direction "A" and the information recorded through the discharge port 5 is discharged.

In addition, when a fax signal is applied, the main board 4 generates a print control signal according to the applied fax signal. In accordance with the print control signal generated from the main board 4, the recording paper stored in the cassette 3a is brought into close contact with the spring 3a-1 and fed by the pickup roller 3c along the recording paper guide 3b.

At this time, the print head 3i reciprocates through the carriage shaft 3i-1, and prints the information according to the fax signal on the recording paper.

When the print job is completed through the print head 3i, the recording paper conveyed in the direction " B " is conveyed through the direction " E " and transferred to the stacker 6 for storage.

On the other hand, when print data is input from a computer (not shown), the input print data is received from the main board 4. The main board 4 receiving the print data generates a print control signal according to the applied print data. The print sheet fed along the direction "D" in accordance with the generated print control signal is fed through the feed roller 3g through the feed guide 3f.

At this time, the printing paper fed through the friction roller 3h is fed one by one. The printing paper fed one by one by the friction roller 3h has a bubble sprayed through the nozzle of the print head 3i which reciprocates through the carriage shaft 3i-1 according to the print control signal. Thus, the print job according to the print data is completed. The printing paper on which such a printing operation is completed is discharged through the direction "E" and stored in the stacker 6 to be stacked.

In addition, the print paper fed in the direction "C" through the paper feeding section 8 is fed through the pickup roller 3d and supported by the support piece 3e to print through the print head 3i according to the applied print data. Will run The print paper on which this print job is completed is also discharged in the direction "E" and stored in the stacker 6.

The selection of all these tasks is selected and output according to the contents input by the user through the operation panel 1a supported by the main body 1. In addition, the front cover 1b is used to open and close the inside of the composite apparatus to solve the operation error when an operation error or the like occurs.

In such a conventional multi-function machine, as the device for reading information recording paper is located at the top of the print head, the center of gravity moves upward, there is no sense of stability, and the document guide is located at the top of the print head. Therefore, the document guide should be higher than the print head, and there is a problem of causing a mistake of the user when storing the recording paper in the cassette.

In addition, the print head, which is a printing device, and the stacker for recording the printed paper are located on the same plane, so to check the printing device, it is inconvenient to remove the stacker and open the front cover. , Due to the increase in height of the installation location of the stacker (Stacker) there is a problem that gives inconvenience and anxiety to the user.

Therefore, in order to solve the conventional problem, the present invention is to place a device for reading the paper on which information is recorded, at the bottom of the printing apparatus, and to integrate the document transfer table and the document guide with a stocker of printed recording paper. An object of the present invention is to provide a multi-purpose device in which a document store and a paper guide are integrated.

The present invention having such an object transfers a document stacker installed on the lower side of the front side of the main body of the multifunction apparatus and a paper on which information stored in the document stacker is recorded to store a paper recording information. In order to read and feed along a path, a scan unit installed in the lower part of the main body of the multi-function device with respect to the side center of the document stacker, and a fax signal or print data or a copy signal are applied to the authorized signal.
