It is about.

In recent years, in line with the pursuit of more efficient office environment and automation trend, devices incorporating various functions have emerged. For example, an image forming apparatus having a facsimile function, a copy function, or a print function in combination.

In other words, office equipment such as fax machines and copiers existed separately according to their functions, but due to the development of various electronic industries and the development of parts thereof, the functions of fax machines, printers, copiers and printers are integrated. Multifunction devices have emerged.

It is common to have a facsimile copy function at present, and the functions common to all three office devices mentioned above may be called printing (forming images on a print medium). The fax includes a scanner unit (reading original) for receiving the original to be sent, an output unit for printing the received original, a fax control circuit unit for controlling overall operations for performing the fax transmission / reception function, and a power unit. At least the branches are structured.

The copying machine has a scanner section for receiving an image to copy, an output section for printing the scanned image, a copy control circuit section and a power section for collectively controlling the overall operation for performing the copy function. The printer has an output unit which receives the image information signaled from the computer and prints it, a print control circuit unit which collectively controls the overall operation to perform the print function, and a power unit.

The commonalities of these devices are that they have both an output and a power. Therefore, if the control circuit unit can be implemented by combining only parts for performing unique functions that are not in common, one multifunction apparatus that performs all three functions may be constructed.

However, these multifunction devices have been reduced in volume rather than having three functions separately, but still have a problem of being larger in size than a single function, and the problem of miniaturization still remains.

Therefore, in order to solve the above problems, a composite device as shown in FIG. 1 has emerged. That is, the composite apparatus includes a paper feeding cassette 126 on which a plurality of recording papers 40 are loaded, and a lever 30 for rotating the recording paper 26 loaded on the paper feeding cassette 126 while rotating in a counterclockwise direction. ) Is installed. On one side of the paper feed cassette 28, a pickup roller 32 for separating and feeding the recording paper 26 is provided. Then, at one side of the pickup roller 32, a feed roller 34 for transferring the fed recording paper 26 to the ink cartridge 14 side is provided. On the upper portion of the feed roller 34, an ink cartridge 14 for forming an image on the recording paper 26 is mounted to the carrier 92.
