Description

TECHNICAL FIELD The present invention relates to an image forming apparatus that has an image display and can use the display as a document.

2. Description of the Related Art A copying machine is an example of a device that optically reads a document and performs image processing. In a typical copying machine, a document placed on a document table made of transparent material is illuminated from below the document table, and the reflected light according to the density of the document is focused by an optical system using lenses, etc. For example, an apparatus has been proposed that can make a hard copy of the output of a computer, etc. (images displayed on a display device or the like without an original) in the same way as a general original.

In the case of display panel copying, a reflective liquid crystal panel arranged in high density is placed on the original holding plate of the copier, and when the original holding plate (original platen cover) is open, the liquid crystal panel displays information. Operate as a display medium for FA
It is used as a form of information transmission as an output terminal for a word processor, etc. from outside the company, connected to an office computer, and if necessary, the information can be transmitted to
・-Put down the cover and scan the display with the illumination as if you were making a normal copy in order to keep it as a copy.

FIG. 1 shows an external view of a writable image forming apparatus. 5ah This is a reflective liquid crystal display for writing the date and time in the margins of originals by copying. This is a case where a large-screen reflective liquid crystal panel manufactured by Company 5b is incorporated into the document cover. Also, it is the same whether the display is the entire cover or a part of the cover, but if the display is a part of the cover, the part to be written at the same time is fixed, so it is necessary to prepare the original for this purpose. The format was determined automatically, and it was impossible to write on arbitrary parts of the manuscript at the same time.

In addition, either cut off the portion of the document that is written simultaneously on the screen in advance, or display the document at 0HP (overhead projector).
) It must be made of a transparent material such as a sheet.1. There was a drawback.

OBJECTS In view of the above points, one object of the present invention is to eliminate the above-mentioned drawbacks and provide an image forming apparatus that can write an image on a display device at an arbitrary location on a document at the same time as an image on the document.

Example The present invention will be described below with reference to the drawings.

FIG. 2 is a perspective view of an electrophotographic copying machine according to an embodiment of the present invention. 1 is the electrophotographic copying machine main body as described above, 2 is a document cover that holds the document in close contact, 5 is a diffused reflection plate, 6 is a document platen made of transparent film) 7 is assembled into the document platen B. It is a reflective type liquid crystal display. This reflective*liquid crystal display 7 does not itself have a reflective plate. This is a knob for moving the document table 6 and the reflective liquid crystal display 7 incorporated in the document table 6 in the horizontal direction (in the direction of the arrow). Note that this is a connection part with an external device such as a 12Fi computer.

In order to explain the principle of movement of the original platen A made of the transparent film, a configuration diagram thereof is shown in FIG. 3.

Reference numeral 6 denotes a document table made of a transparent film, and 7 denotes a reflective liquid crystal display having the length of one side of the document placement area built into the document table B. However, this liquid crystal lO 2 display does not have a reflective plate. The actual manuscript is placed within the frame indicated by the toga.

9L and 9R are rollers for winding up the transparent film constituting the document table 6, and by moving the knob 8 in the direction of the arrow (transverse direction), the transparent film and the liquid crystal display 7 move in that direction. Note that the transparent film rollers 9L and 9 are connected by a stopper 10.

For example, prepare a document with a blank area where you want to write simultaneously with the displayed content as shown in FIG. Move to the simultaneous writing part of the displayed content, enter the characters you want to write on display 7 from an external device (for example, a personal computer with a keyboard: not shown), and place the original on the document table B as in normal copying. If a copy is made using ε, a copy as shown in FIG. 4(b) can be obtained.

Note that, as described above, the reflective liquid crystal display is not equipped with a reflective plate. In other words, as mentioned above, original ii 1°
When display contents are simultaneously written on a part of S, the blank part of the document is used as a diffused reflection plate of the display 7.

Also, when copying onto copy paper that is larger than the original,
When display contents are written in the margins of the photographic paper, the diffused reflection plate attached to the document cover 2 is used as the diffused reflection plate of the display 7, thereby making it possible to write the display contents at the same time.

Furthermore, in this apparatus, if the screen of the display 7 is set to a normal margin, the copying machine 1 can of course be used for general document copying.

In addition, the moving direction (horizontal direction) of the display 7 shown in FIG.
The position of the displayed content in the direction perpendicular to the display can be specified by an external device, such as a personal computer with a keyboard (not shown), which is connected to the display 7 by a cable or the like. Therefore, the horizontal position of the displayed content is determined by the moving device shown in FIG. 3, and the vertical position is determined by an external device.

In addition, if you do not want to copy a part of the document for reasons such as security protection, you can display that part on the screen of the display unit 7 (in other words, display it in black) and copy it. It becomes possible to take a masked copy.

In the embodiment described above, the display is movable in the horizontal direction, but the same effect can be achieved even if one moving device is attached to the display so as to move it in the vertical direction.

Further, by using the above-described masking of the original, for example, the copying machine 1 uses a filter or the like to filter light reflected from the original into 3.
(In the case of a so-called color copier, which has 6 cycles to separate the primary colors and develop them with complementary color toners) If you mask the original in only 1 of the 3 cycles, you can make the masked part a different color from the original. You can make developed copies. For example, it is possible to make a copy of a white and black document with the parts to be emphasized colored red, blue, or green.

Effects As explained above, the present invention has a planar display device, the display device can be used as a document, it can be moved to any place on the document table, and it can be used in general It has become possible to provide an image forming apparatus capable of making a copy by writing on the screen of the display device simultaneously with the original on an arbitrary part of the original or a margin part of copy paper.
