2. Description of the Related Art In a laptop type document processing apparatus having a built-in printing apparatus, an LCD as shown in FIG.
Since the printing device is disposed behind the display unit 41 composed of (liquid crystal display plate) and the insertion port 42 for the printing paper is also behind the display unit 41, when printing, for example, the display unit 41 is moved forward. The print head 43 is turned over to insert the print paper 43 through the insertion slot 42, and the print head 44 prints. 45 is an ink ribbon for printing. The printing paper 43 inserted from the insertion port 42 is fed to a predetermined position by the paper feed roller 46 and printing is performed, but in the case of a laptop type, the printing apparatus is also required to be downsized from the viewpoint of portability, A paper feed roller 46 having a small diameter is used. Therefore, the printing paper 43 is
The paper may be bent by 46, and depending on the type of the paper (eg, envelope, postcard, etc.), the paper may be taken out in a warped state (warp), and the warp may have to be corrected after printing. Further, since the insertion port for the printing paper is located behind the display unit 41, the display unit 41 has to be tilted forward as described above during printing, which makes it difficult to see the print menu or the like displayed on the screen. .

The document processing apparatus main body 1 is placed on the paper feeding device 2 in an overlapping manner. Reference numeral 3 is a keyboard, and 4 is a display unit including an LCD or the like. 5 is a print head, 6 is an ink ribbon for printing, 7 is a printed printing paper, and the printing paper 7 is supplied along a guide piece 9 from a paper feed port 8 formed in the bottom surface of the document processing apparatus main body 1. Then, it is transferred upward by the transfer roller 10, printed by the print head 5, and sent out from the sending port 11 in the direction of the arrow. Reference numeral 12 denotes a signal output terminal portion for outputting a paper feed signal or the like to the paper feeding device 2, which is provided on the bottom surface of the document processing device main body 1.
By placing the document processing apparatus main body 1 on the paper feeding device 2, the document processing device main body 1 is connected to the signal input terminal portion 13 on the upper surface of the paper feeding device 2. In these input / output terminal portions, for example, at least one of the contact pieces has a curved shape and is arranged so as to face the other contact piece and is connected by pressing.

Reference numeral 14 is a paper tray, which is pulled out and inserted in front of the housing of the paper feeding device 2 (left in the drawing). Reference numeral 15 is a sheet push-up plate, one end (left side of the figure) of which is rotatably supported by the sheet tray 14, and the other end of which is biased upward by a biasing spring 17.
The upper surface of the printing paper 16 is pressed against the paper guide 18 so that the mounted printing paper 16 is drawn into the paper feed roller 19. The paper feed roller 19 is driven by a paper feed motor (not shown) in response to a signal output from the document processing apparatus main body 1 via the signal input terminal portion 13, and holds the print paper 16 with the transfer roller 20 to feed the paper upward. .

Is placed in the recess 23 so that the position of the paper feed port 8 of the document processing apparatus body 1 coincides with the position of the print paper feed port of the paper feed device 2.

Reference numerals 31 and 32 in FIG. 2 denote sheet partition plates which can be manually moved in the directions of the arrows and are moved to appropriate positions according to the size of the printing sheet. 33 in FIG. 3 is a pointer,
It can be seen from the outside through a hole 34 provided on the side of the sheet push-up plate 15 and formed in the side surface of the housing of the sheet feeding device 2. The upper and lower positions of the sheet push-up plate 15, that is, the remaining amount of printing paper. Since it moves in accordance with, the approximate remaining amount of printing paper is notified by the position indicated by the scale 35. It should be noted that in the above description, the connection portion of the paper feed signal or the like from the document processing apparatus main body 1 to the paper feeding apparatus 2 is automatically connected by placing the document processing apparatus main body 1 on the paper feeding apparatus 2. However, a connector socket may be provided on the side surface of the housing of the document processing apparatus main body 1, and a connector plug from the sheet feeding device 2 may be inserted and connected.
