Then, between the vicinity of the paper feed roller 14 and the vicinity of the transfer device 9, the paper in the cassette case 13 is transferred to the transfer device 9.
A paper feed path 15 is provided for conveying the paper to.

A portion of the guide plate constituting the paper feed path 15 is cut out, and a pair of upper and lower registration rollers 16 are disposed in the cutout portion.

A fixing device 19 is provided on the other side of the inner lower part of the main body 1, and a paper conveyance path 20 is provided between the fixing device 19 and a separation device 10 provided near the photosensitive drum 5. A paper discharge section 21 is provided on the opposite side of the fixing device from the conveyance path 20, and a paper discharge tray 22 is provided outside of the paper discharge section 21.

A scale plate 25 is placed on the upper left end of the original glass stand 2 of the electrophotographic copying apparatus configured as described above, and a liquid crystal display is provided between the scale plate 25 and the original glass stand 2. A section 26 is provided.

That is, as shown in FIG. 11, this display section 28 includes a transmission type liquid crystal section 76 located on the top surface of the original glass table 2, and an EL (electroluminescence) 77 provided on the top surface.
These are integrated into the scale plate 25.
It is arranged in the lower opening 7B of.

The display section 26 is connected to a central processing unit (CPU) as shown in FIG. An operation panel 58 of the electrophotographic copying apparatus that causes the liquid crystal display section 26 to display information is connected thereto.

When obtaining a copied image using the electrophotographic copying apparatus configured as described above, an original is first placed on the upper surface of the original glass stand 2. In this case, the edge of the document is brought into contact with the scale plate 25 to set the document at a proper placement position, and then the document is covered with the platen cover 3 and the operation panel 58 is operated.

This operation panel 58 is as shown in FIG.
When the number of copies is selected using the numeric keypad 70, the selected number is displayed on the set number of copies display LED 69. Also 68
is the auto mode key, and when pressed, the mechanism (APS) detects the original size and automatically determines which size paper to feed, and automatically determines the original density and adjusts the copy density. The cassette selection key 6 operates the mechanism (EEv!A mechanism) for setting the

Furthermore, a plurality of other groups of keys are added to the operation panel 58, and the functions of these keys will be described later.
1 and a print key 62.

Then, by turning on the numeric keypad 70 and auto mode key 68 and then turning on the copy start key 72, the copying operation is started, the photosensitive drum 5 starts rotating, and the charging device 6 is also started, and the photosensitive drum 5 Electrification is applied to the outer peripheral surface of the At the same time, the paper feed roller 14 also starts rotating, and the uppermost paper among the papers in the cassette case 13 is conveyed through the paper feed path 15, and when this paper reaches the registration roller 16, the micro It is detected by a detection member (not shown) such as a switch and stops at that position.

At the same time that the paper reaches the registration rollers 16, the exposure lamp of the exposure device 4 turns on and illuminates the lower surface of the original glass table 2, and the exposure optical system consisting of the exposure device 4 and the lens group 24 starts moving. Then, an electrostatic latent image corresponding to the original image is formed on the circumferential surface of the photosensitive drum 5.

Thereafter, as the photoreceptor drum 5 rotates, the electrostatic latent image is developed by a developing device 8 to become a toner image and positioned opposite to a transfer device 9.

On the other hand, the paper is conveyed through the paper feed path 15 by the activation of the registration roller 16 to a position facing the transfer device 9, so that the toner image on the outer peripheral surface of the photoreceptor drum 5 is transferred to the paper by the transfer device 9. After being separated by the separation device 10, the paper is conveyed to the fixing device 19 via the conveyance path 20, where it is fixed and discharged onto the paper discharge tray 22.

Further, the photoreceptor drum 5 is cleaned by the static eliminator 11 and the cleaning device 12, and one stroke is completed.
And the charging device 6 stops operating.

The above operation is then performed for a set number of sheets.

In an electrophotographic copying apparatus that operates as described above, various types of additional information are written on a copied image in the following manner.

First, when the print key 62 of the operation panel 58 is pressed, the central processing unit (CPU) enters a state in which additional information is written on a normal copy image, that is, a state is displayed on the display section 26.

Further, when the print key 62 is pressed, a reduction mode is entered in order to write additional information on a part of the copied image.

A suitable reduction rate is about 2%, and the magnification is Xo, 9B. With this magnification, the size will not change much from the original manuscript, and moreover, you will have enough space to write additional information.

As an example of this reduction, if a 2% reduction is included in the general magnification, ×1.0 becomes Xo, 9B, and Xo, 81 becomes ×0°7.
9, x0.71 is Xo, 69 is Xl, 24 is X 1
．． 22, and the method of moving the lens group 24 to this reduction ratio is to use a pulse motor, and it is possible to provide a home position sensor (for example, Xl, 0) and control the motor with the number of pulses from there. It is possible.

Then, as described above, the document information and additional information can be copied by automatically reducing the size and speeding up the feeding of the registration rollers 16 when the print key 62 is pressed.

After turning on the print key 62 on the operation panel 58, the next step is to input additional information from the keys on the operation panel 58 and display it on the display section 26, or display it using a card on which additional information, which will be described later, is recorded. The display on the section 26 is selected by turning the character entry key 59 ON or OFF.

Therefore, when the character input key 59 is turned on, the character input mode is selected, and since this character input mode is further divided into a katakana mode and an alphabet mode, for example, the katakana mode is selected by the mode switching key 61. In katakana mode, input is performed using the following method.

First, a character is selected using the numeric keypad 70 according to the address in the code table shown in FIG. For example, 4 on the numeric keypad 70.
If you input 2, this 4.2 will display the set number of sheets LED 69.
is displayed, and if you press the set key 60 after this, this 4,
The address corresponding to 2, ie, "S" is input and displayed on the display section 26 (FIG. 9(a)). Similarly, 2.0
And when the cent key 60 is turned on, "tsu" is displayed (Fig. 9(b))
), and when 2, 6 and set key 60 are turned on, "mu" is turned on (FIG. 9(c)), and then 0, 1 and set key 60 are turned on.
When the button is turned on, "power" is input (FIG. 9(d)), and the display section 26 displays "So", "Tsu", "Mu", and "Power".

Furthermore, before the set key 60 is turned on, a cursor 75 is located at the bottom of the display section 26;
A display corresponding to the input is displayed in the upper row where is located. Furthermore, when erasing the upper row of characters where the cursor 75 was located, the stop clear key 71 may be turned on.

This cursor 75 is designed to move to adjacent display positions one by one by inputting two numbers to specify an address as described above and then pressing the SET key 60. If you want to create a blank, press any one of the density setting keys 67 to move the cursor 75 in the direction of the arrow shown on the surface of the density setting key 67.

Furthermore, when switching from katakana mode to alphabet mode, turning on the mode switching key 61 changes to alphabet/nod mode.

As a result, even in the alphabet mode, input is made according to the address in the code table shown in FIG. 10, as in the katakana mode.

In this case, in Katakana mode and Alphabet mode, the addresses of numbers and various symbols are shared, making it easier to handle them.

After displaying an arbitrary display on the display section 26 through the above operations, if a copying operation is started using the copy start key 72, an electrostatic latent image corresponding to the display section 26 and document information will be displayed on the photoreceptor drum 5 during exposure. After that, it becomes a toner image in the developing device 8, and when it passes through the transfer and separation area, the document information and the contents of the display section 26, that is, additional information are recorded.

In this case, the display section 26 includes a transmissive liquid crystal section 76 and an EL
7'7, when an arbitrary display is performed on the transmissive liquid crystal section 76, the EL 77 provided on the upper surface is also energized, so the EL 77 emits light, while the transmissive liquid crystal section 76 Since an electric field is applied to 76, the parts other than the displayed content such as characters are transparent, so the emitted E
Since the light of L77 is transmitted through the transmissive liquid crystal section 76 for exposure, image fogging of the copied image due to the ground color of the transmissive liquid crystal section 76 does not occur. Further, the exposure device 4
Since the distance from the display unit 26 matches the document information on the document glass table 2, a clear copy image can be obtained.

The position of the additional information in this copied image is determined by the scale plate 25.
If the position is as shown in Fig. 12 (a), the first
3 (a), in the case of (b) of Fig. 12, it is shown in Fig. 13 (b), and in the case of (C) of Fig. 12, it is shown in Fig. 13 (C).
It is recorded as 1.

In this case, when the leading edge of the original is brought into contact with the scale plate 25, it appears at position I, and when the trailing end is brought into contact with it, it appears at position -. If the additional information is the distribution destination, position I in Figure 13 (C) is located, if the additional information is the publisher and date, it is located in Figure 13 (a), and if it is a page, it is in Figure 13 (b). ) is suitable, and the display section 26 is located at (b) in Fig. 12.
It can be applied to all document sizes if the position is as follows.

Next, the display part 26 uses the card that stores the additional information.
When displaying, first turn off the character input key 59.
state. As a result, only the print key 62 is turned on, and preparation for reading the card is completed.

Then, by simply placing a plurality of cards on a tray in the card reading device 30 shown in FIGS. 3 to 6, the stored contents of the cards are displayed on the display section 26. That is, when a plurality of cards 54 are placed on the tray 39 and the door 49 is closed, both trays 39 and 40 are raised by drive members (not shown), and one tray 39 has a stack of cards 54 on the upper surface of the conveyor belt 34. When it comes into contact with the lower surface, a sensing member (not shown) stops the driving member at that position. Further, the other tray 40 stops at a distance of one card from the conveyor belt 34.

Next, when the copy start key 72 is pressed, the movable stopper 35 is lowered and at the same time the conveyor belt 34 is activated to convey the card on the tray 39. Further, since the movable stopper 36 is in a protruding position, the conveyed card comes into contact with the movable stopper 36, and when the card reaches the upper part of the reading member 41 is detected by the detection member 42, the conveyor belt 36
4 stops, and the movable stopper 35 rises to prevent the next card from being conveyed. The memory contents of the card are read by the central processing unit (C) by the reading member 41.
PU), the contents are displayed on the display section 26 via the driver. As a result, the contents of the display section are copied together with the original image.

When processing of the first card is completed, the movable stopper 36 is lowered, the conveyor belt 34 is moved to the top of the tray 40, the tray 39 is raised by the thickness of one card, and the tray 40 is The next card is moved down by one thickness and is moved by the conveyor belt 34 and positioned above the reading member 41 in the same manner as before. and conveyor belt 3
When the tray 39 finishes feeding the last card, the tray 39 descends to the initial state, and when the ejection of the last card is completed, the tray 40 also descends to the initial state.

In addition, when using only one card, if the card is inserted into the insertion slot 55 of the door 49 of the reading device 30, the card will be located on the top surface of the reading member 41, and the detection member 43 will be located on the back side in the insertion direction. After the card is read, the conveyor belt 34 transfers the card to the tray 40 by a driving member.
It is placed at the top.

Therefore, even if a card is used, the display section 2
6 is configured to be able to display the contents stored on the card.

Note that the central processing unit (C, P U) has a buffer RA.
Since M is connected, the contents of the display section 26 can also be registered on the card via the card reading device 30 (also used as a writing device).

〔Effect of the invention〕

By configuring the present invention as described above, even when additional information is copied together with original information, image fogging or distortion does not occur in the image portion corresponding to the additional information.
Furthermore, since EL is used, the entire display section can be made thinner and the platen cover can be prevented from lifting up, which has excellent effects such as the ability to obtain high quality copied images.
